  Background Motivation and self-efficacy are well-established predictors of engagement and persistence within structured exercise programmes. Yet it remains unclear whether these psychological factors predict objective adherence metrics and associated fitness outcomes within home-based exercise programmes for older adults. Methods This study adopted a person-centred approach to examine whether distinct psychological profiles predict objective adherence and fitness outcomes following a 26-week home-based exercise programme in 88 older adults (age = 67.2 ± 5.5 years). Objective adherence was defined as compliance with the prescribed exercise volume and quantified using cumulative metabolic equivalent minutes (MET-mins) derived from heart rate data reflecting session intensity and duration across the programme, as opposed to behavioural self-report measures. Psychological profiles were generated using latent profile analysis based on autonomous motivation, controlled motivation, and exercise self-efficacy. Results Two profiles were identified: an autonomous and highly confident profile characterised by high selfefficacy and autonomous motivation, and a moderately autonomous and confident profile characterised by lower self-efficacy and autonomous motivation. Controlled motivation was similar between groups. Profiles did not differ in demographic or physiological characteristics at baseline. Adherence was high and comparable across the two profiles for all indices (e.g., cumulative MET-mins: 129 ± 66% vs. 116 ± 38%). Furthermore, both profiles demonstrated significant and comparable improvements in cardiorespiratory fitness (V̇O₂peak), handgrip strength, flexibility (chair sit-and-reach; back scratch), and mobility (8-foot up-and-go). Conclusions Baseline differences in self-efficacy and autonomous motivation among older adults did not significantly predict adherence or fitness outcomes within a structured, well-supported home-based exercise programme. The programme incorporated consistent objective monitoring of exercise behaviour, along with regular guidance and feedback from the research team delivered through scheduled participant contact. This level of structured behavioural support may have reduced the influence of psychological profile membership on exercise adherence and fitness outcomes, resulting in comparable positive outcomes across participants. Future research should investigate whether motivation profiles become more predictive of long-term adherence and sustained fitness outcomes once external behavioural support is reduced or withdrawn.

  Background High-intensity interval training (HIIT) was originally designed to improve athletic performance, but a growing body of research over the past decade has highlighted its positive impact on various other health outcomes. However, concerns exist regarding HIIT’s suitability for those unaccustomed to regular exercise, as its high intensity may impact tolerance and adherence. Therefore, this study aimed to assess the associations between various objective adherence metrics and the resultant changes in peak oxygen uptake (V̇O2PEAK) and lactate threshold (LT) in older adults completing six-month home-based HIIT. Methods Healthy older adults (n = 233, 60–84 years, 54% female) were randomized to six-month, thrice-weekly home-based HIIT or a passive control group. Adherence in the HIIT group was objectively monitored using a Polar watch and heart rate sensor and quantified as frequency (sessions/week), intensity (minutes ≥ 80% HRPEAK/session), duration (session duration, min), and total adherence (cumulative MET-min; overall exercise volume summed across sessions from session duration and mean %HRPEAK). For each metric, adherence was expressed as a percentage of completion relative to the planned amount. V̇O2PEAK and LT were assessed using a modified Balke treadmill protocol to volitional exhaustion. To account for multicollinearity, partial least squares regression (PLSR) models assessed associations between adherence metrics and changes in V̇O2PEAK or LT. Results The PLSR analysis, accounting for baseline V̇O2PEAK, age, sex, and country where data-collection took place, revealed a positive association between post-test V̇O2PEAK and total adherence (Selectivity fractions (SF) = 0.70 [0.19; 0.93]), frequency adherence (SF = 0.54 [0.08; 0.86]), and intensity adherence (SF = 0.44 [0.07; 0.80]), but not with duration adherence (SF = 0.11 [− 0.08; 0.54]). For LT, PLSR analysis revealed no associations with any adherence metrics. Conclusions Superior HIIT adherence (i.e., total, frequency, and intensity) was associated with larger V̇O2PEAK gains in older adults. Notably, total adherence demonstrated the strongest predictive contribution among the adherence metrics, suggesting that overall exercise volume may be especially relevant for improving V̇O2PEAK in this context. In contrast, adherence metrics did not predict changes in LT, despite the exercise group experiencing significant LT improvements, indicating that LT adaptations were not strongly explained by variation in HIIT adherence in this sample.

  Exercise training has been proposed to counteract age-related cognitive decline through improvements in cardiorespiratory fitness (CRF hypothesis). Research has focused on cognitive domains like attention and processing speed, and one cross-sectional study reported a positive relationship between CRF and language production in older adults. In a randomized controlled trial, we investigated whether these benefits could extend to language comprehension in healthy older adults, and whether bilinguals, for whom language processing is more costly, would exhibit greater benefits than monolinguals. Eighty older English monolinguals and 80 older Norwegian-English bilinguals were randomized into either a 6-month exercise training group or into a passive control group. We assessed CRF (VO2peak) and language comprehension (reaction times to spoken word monitoring) in first (L1, all participants) and second language (L2, bilinguals only), before and after the intervention. We found that monolinguals in the exercise group (compared to the control group) were faster in comprehension following the intervention. Moreover, this effect was mediated by exercise-induced increases in VO2peak, supporting the CRF hypothesis. This extends previous cross-sectional research and establishes a causal link between exercise training and speeded comprehension in older monolinguals. However, despite inducing increased VO2peak, exercise training did not affect bilingual (L1 or L2) comprehension, and bilinguals in both groups were slower after the intervention period. Exploratory analyses suggested that this slowing may be driven by participants with low L2 proficiency, but further research is needed to examine whether bilingual language processing is in fact unaffected by exercise training and its consequent improvements in CRF.

  Background This study aimed to investigate the effectiveness of a 6-month home-based high-intensity interval training (HIIT) intervention to improve peak oxygen consumption (V̇O2peak) and lactate threshold (LT) in older adults. Methods Two hundred thirty-three healthy older adults (60–84 years; 54% females) were randomly assigned to either 6-month, thrice-weekly home-based HIIT (once-weekly circuit training and twice-weekly interval training) or a passive control group. Exercise sessions were monitored using a Polar watch and a logbook for objective and subjective data, respectively, and guided by a personal coach. The outcomes were assessed using a modified Balke protocol combining V̇O2peak and LT measures. General linear regression models assessed between-group differences in change and within-group changes for each outcome. Results There was a significant between-group difference in the pre-to-post change in V̇O2peak (difference: 1.8 [1.2; 2.3] mL/kg/min; exercise: +1.4 [1.0; 1.7] mL/kg/min [~5%]; control: −0.4 [−0.8; −0.0] mL/kg/min [approximately −1.5%]; effect size [ES]: 0.35). Compared with controls, the exercise group had lower blood lactate concentration (−0.7 [−0.9; −0.4] mmol/L, ES: 0.61), % of peak heart rate (−4.4 [−5.7; −3.0], ES: 0.64), and % of V̇O2peak (−4.5 [−6.1; −2.9], ES: 0.60) at the intensity corresponding to preintervention LT and achieved a higher treadmill stage (% incline) at LT (0.6 [0.3; 0.8]; ES: 0.47), following the intervention. Conclusion This study highlights the effectiveness of a home-based HIIT intervention as an accessible and equipment-minimal strategy to induce clinically meaningful improvements in cardiorespiratory fitness in older adults. Over 6 months, the exercise group showed larger improvements in all outcomes compared with the control group. Notably, the LT outcome exhibited a more pronounced magnitude of change than V̇O2peak.

  Aim The present systematic review and meta-analysis aimed to compare the effect of moderate- versus high-intensity aerobic exercise on cardiorespiratory fitness (CRF) in older adults, taking into account the volume of exercise completed. Methods The databases MEDLINE (Ovid), EMBASE (Ovid), and CENTRAL (Cochrane Library) were searched to identify randomized controlled trials (RCTs). Two reviewers extracted data and assessed bias. Comprehensive Meta-Analysis software calculated overall effect size, intensity differences, and performed meta-regression analyses using pre-to-post intervention or change scores of peak oxygen uptake (V̇O2peak). The review included 23 RCTs with 1332 older adults (intervention group: n = 932; control group: n = 400), divided into moderate-intensity (435 older adults) and high-intensity (476 older adults) groups. Results Meta-regression analysis showed a moderate, but not significant, relationship between exercise intensity and improvements in V̇O2peak after accounting for the completed exercise volume (β = 0.31, 95% CI = [−0.04; 0.67]). Additionally, studies comparing moderate- versus high-intensity revealed a small, but not significant, effect in favor of high-intensity (Hedges' g = 0.20, 95% CI = [−0.02; 0.41]). Finally, no significant differences in V̇O2peak improvements were found across exercise groups employing various methods, modalities, and intensity monitoring strategies. Conclusion Findings challenge the notion that high-intensity exercise is inherently superior and indicate that regular aerobic exercise, irrespective of the specific approach and intensity, provides the primary benefits to CRF in older adults. Future RCTs should prioritize valid and reliable methodologies for monitoring and reporting exercise volume and adherence among older adults.

  It is well-established that cross-sectional measurements of poor body composition are associated with impaired physical function and that power training effectively enhances total lean mass and physical function in older adults. However, it is unclear if power training-induced changes in body composition are associated with improved physical function in older adults. Aim: The present study investigated associations between body composition and physical function cross-sectionally and with power training-induced changes in older men. Methods: Forty-nine older men (68 ± 5 yrs) completed a 10-week biweekly power training intervention. Body composition was measured using dual-energy X-ray absorptiometry. Physical function was assessed as a composite Z-score combining measures from Sit-to-stand power, Timed up-and-go time, and loaded and unloaded Stair-climbing time (15 steps). Linear and quadratic regression analyses were performed to assess associations between body composition and physical function. Results: At baseline, total (R2 = 0.11, p < 0.05) and percentage body fat (R2 = 0.15, p < 0.05) showed a non-linear relationship with physical function. The apex of the quadratic regression for body composition was 21.5% body fat. Furthermore, there was a non-linear relationship between changes in body fat percentage and physical function from pre- to post-intervention (R2 = 0.15, p < 0.05). Conclusion: The present study’s findings indicate that participants with a body composition of ~20% body fat displayed the highest level of physical function at baseline. Furthermore, despite small pre–post changes in body fat, the results indicate that those who either preserved their body fat percentage or experienced minor alterations observed the greatest improvements in physical function.

  The study aimed to investigate the effectiveness of an individualized power training program based on force–velocity (FV) profiling on physical function, muscle morphology, and neuromuscular adaptations in older men. Forty-nine healthy men (68 ± 5 years) completed a 10-week training period to enhance muscular power. They were randomized to either a generic power training group (GPT) or an individualized power training group (IPT). Unlike generic training, individualized training was based on low- or high-resistance exercises, from an initial force–velocity profile. Lower-limb FV profile was measured in a pneumatic leg-press, and physical function was assessed as timed up-and-go time (TUG), sit-to-stand power, grip strength, and stair-climbing time (loaded [20kg] and unloaded). Vastus lateralis morphology was measured with ultrasonography. Rate of force development (RFD) and rate of myoelectric activity (RMA) were measured during an isometric knee extension. The GPT group improved loaded stair-climbing time (6.3 ± 3.8 vs. 2.3% ± 7.3%, p = 0.04) more than IPT. Both groups improved stair-climbing time, sit to stand, and leg press power, grip strength, muscle thickness, pennation angle, fascicle length, and RMA from baseline (p < 0.05). Only GPT increased loaded stair-climbing time and RFD (p < 0.05). An individualized power training program based on FV profiling did not improve physical function to a greater degree than generic power training. A generic power training approach combining both heavy and low loads might be advantageous through eliciting both force- and velocity-related neuromuscular adaptions with a concomitant increase in muscular power and physical function in older men.

  Older adults’ physical activity (PA) is low. We examined whether eight months of resistance training increased PA level in community-dwelling older adults receiving home care. A two-armed cluster-randomized trial using parallel groups was conducted. The included participants were >70 years and received home care. The resistance training group performed resistance training using body weight, elastic bands, and water canes twice per week for eight months. The control group was informed about the national PA guidelines and received motivational talks. The ActiGraph GT3X+ accelerometer was used to estimate PA. Outcomes included total PA (counts per minute), sedentary behavior (min/day), light PA (min/day), moderate-to-vigorous PA (min/day), and steps (mean/day). Between-group differences were analyzed using multilevel linear mixed models. Twelve clusters were randomized to either resistance training (7 clusters, 60 participants) or the control group (5 clusters, 44 participants). A total of 101 participants (median age 86.0 (interquartile range 80–90) years) had valid accelerometer data and were included in the analysis. There were no statistically significant between-group differences for any of the PA outcomes after four or eight months. This study offers no evidence of increased PA level following resistance training in older adults with home care

  Purpose: The overall aim of the present study was to explore the experiences of older adult exercisers participating in an individualized training program lasting 3 months preparing for completing a triathlon competition. Methods: Fourteen older Norwegian adults (median age (interquartile range, IQR) for males (N=10) and females (N=4) were 70.0 (65.0-75.5) and 57.5 (56.3-62.5) years, respectively) participated in 3-month individualized training program comprising three weekly sessions of running, cycling, and swimming. Both field- and laboratory-based testing were conducted. The participants attended two sports nutrition and competitive psychology seminars focusing on triathlon competition. The participants were interviewed in depth in three different focus groups. Thematic analysis was utilized to analyze the findings. Results: Participants improved their performance in all field-based tests. After completion of the thematic data analysis the main finding and overarching theme of well-being and being fit emerged. Additionally, three main themes were identified: 1) motivation; 2) progress and coping; and 3) breaking barriers. Conclusion: Psychological well-being and satisfaction of being fit seem to be vital to participate in a triathlon competition. Promoting specific age-appropriate participation in sports activities can be an effective strategy for promoting a healthy lifestyle among the elderly.

  Background: To develop effective health promotional and preventive prenatal programs, it is important to understand perceived barriers to leisure-time physical activity during pregnancy, including exercise and sport participation. The aims of the present study was 1) to assess the effect of prenatal lifestyle intervention on the perceived barrier to leisure-time physical activity during pregnancy and the first year after delivery and 2) identify the most important perceived barriers to leisure-time physical activity at multiple time points during and after pregnancy. Methods: This secondary analysis was part of the Norwegian Fit for Delivery study, a combined lifestyle intervention evaluated in a blinded, randomized controlled trial. Healthy, nulliparous women with singleton pregnancy of ≤20 gestational weeks, age ≥ 18 years and body mass index ≥19 kg/m2 were recruited via healthcare clinics in southern Norway, including urban and rural settings. Participants were randomized to either twice-weekly supervised exercise sessions and nutritional counselling (n = 303) or standard prenatal care (n = 303). The principal analysis was based on the participants who completed the standardized questionnaire assessing their perceived barriers to leisure-time physical activity at inclusion (gestational week 16, n = 589) and following intervention (gestational week 36, n = 509), as well as six months (n = 470) and 12 months (n = 424) postpartum. Results: Following intervention (gestation week 35.4 ± 1.0), a significant between-group difference in perceived barriers to leisure-time physical activity was found with respect to time constraints: “... I do not have the time” (intervention: 22 vs. control: 38, p = 0.030), mother-child safety concerns: “... afraid to harm the baby” (intervention: 8 vs. control: 25, p = 0.002) and self-efficacy: “... I do not believe/think that I can do it” (intervention: 3 vs. control: 10, p = 0.050). No positive effect was seen at postpartum follow-up. Intrapersonal factors (lack of time, energy and interest) were the most frequently perceived barriers, and consistent over time among all participants. Conclusion: The intervention had effect on intrapersonal perceived barriers in pregnancy, but not in the postpartum period. Perceived barriers to leisure-time physical activity were similar from early pregnancy to 12 months postpartum.

  Introduction: The beneficial effects of physical activity during pregnancy for the mother and offspring have been reported by several studies but there are conflicting results concerning the possible effect of physical activity on the course of labor and risk of cesarean delivery. This study presents secondary analyses from the Norwegian Fit for Delivery randomized controlled trial, aiming at studying the effect of a lifestyle intervention including group exercise classes, as well as the possible influence of physical activity level in late pregnancy, on labor outcomes. Material and methods: Healthy nulliparous women with singleton pregnancy were randomized to an intervention group, n = 303 (dietary counseling and twice‐weekly exercise classes) or a control group, n = 303 (standard care). The participants were analyzed both by randomization and as a cohort comparing women with lowest (quartile 1, 0 metabolic equivalent of task‐hours moderate‐to‐vigorous physical activity/week) (n = 140) vs. highest (quartile 4, ≥16 metabolic equivalent of task‐hours moderate‐to‐vigorous physical activity/week) (n = 131) physical activity level in late pregnancy, assessed with the International Physical Activity Questionnaire. Result: The intervention group had a longer first stage of labor compared with the control group (293 ± 202 min vs. 257 ± 181 min, p = 0.030). No differences between the randomization groups were seen for time spent in second stage of labor, prolonged labor or mode of delivery. In the total sample, women with the highest physical activity level had lower odds ratio (OR) of acute cesarean delivery (OR 0.33, 95% CI 0.11–0.97, p = 0.044) than did those with the lowest physical activity‐level. Conclusion: A significantly longer first stage of labor was observed in the intervention group than in the control group. A high physical activity level in late pregnancy was associated with lower odds of acute cesarean delivery compared with a low physical activity level.

  Background: The International Physical Activity Questionnaire short-form (IPAQ-SF) is frequently used to assess physical activity (PA) level in the general adult population including pregnant women. However, the reliability and validity of the questionnaire in pregnancy is unknown. Therefore, the aims of the present study were to investigate test-retest reliability and concurrent validity of IPAQ-SF among pregnant women, and whether PA is reported differently among those who fulfill (active) vs. do not fulfill (inactive) recommendations of ≥150 min of weekly moderate intensity PA in pregnancy. Method: Test-retest reliability was examined by answering IPAQ-SF twice, two weeks apart (n = 88). To assess validity, IPAQ-SF was compared to the physical activity monitor SenseWear Armband® (SWA) (n = 64). The participants wore SWA for 8 consecutive days before answering IPAQ-SF. PA level was reported as time spent in moderate-, vigorous- and moderate-to-vigorous intensity PA (MPA, VPA and MVPA) corresponding to the cut-off points 3–6, >6 and >3 Metabolic Equivalents (METs), respectively. Results: Test-retest intraclass-correlation of MPA, VPA and MVPA ranged from 0.81-0.84 (95% Confidence Intervals: 0.69,0.90). Comparing time spent performing PA at various intensities; the mean differences and limits of agreement (±1.96 Standard Deviation) from Bland-Altman plots were−84 ± 402 min/week for MPA,−85 ± 452 min/week for MVPA and 26 ± 78 min/week for VPA, illustrating that the total group under-reported MPA by 72% and MVPA by 52%, while VPA was over-reported by 1400%. For the inactive group corresponding numbers were 44 ± 327 min/week for MPA, 52 ± 355 min/week for MVPA and 16 ± 33 min/week for VPA, illustrating that the inactive group over-reported MPA by 13% and MVPA by 49%, while VPA was not detected by SWA, but participants reported 16 min of VPA/week. In contrast, corresponding numbers for the active group were−197 ± 326 min/week for MPA,−205 ± 396 min/week for MVPA and 35 ± 85 min/week for VPA, illustrating that the active group under-reported MPA by 81% and MVPA by 60%, while they over-reported VPA by 975%. Conclusion: IPAQ-SF had good test-retest reliability, but low to fair concurrent validity for MPA, VPA and MVPA compared to an objective criterion measure among pregnant women. Further, women fulfilling PA guidelines in pregnancy under-reported, while inactive women over-reported PA level.

  Background: Muscular strength is associated with functional ability in elderly, and older adults are recommended to perform muscle-strengthening exercise. Understanding how improved muscle strength and -mass influence general and specific domains of quality of life is important when planning health promotion efforts targeting older adults. The aims of the present study were to describe changes in health-related quality of life (HRQOL) in older men participating in 12 weeks of systematic strength training, and to investigate whether improvements in muscle strength and muscle mass are associated with enhancements in HRQOL. Methods: We recruited 49 men aged 60–81 years to participate in an intervention study with pre-post assessment. The participants completed a 12-week strength training program consisting of three sessions per week. Tests and measurements aimed at assessing change in HRQOL, and changes in physical performance (maximal strength) and physiological characteristics. HRQOL was measured using the 12-item short-form survey (SF-12). Muscle mass was assessed based on changes in lean mass (leg, trunk, arm, and total), and strength was measured as one-repetition maximum in leg extension, leg press, and biceps curl. Results: Two of the eight HRQOL SF-12 scores, role physical and general health, and the physical component summary scores, increased significantly during the intervention period. Small significant positive correlations were identified between improvements in muscle strength, and better physical and social function. Moreover, a significant increase in total muscle mass was seen during the intervention period. Conclusions: The positive, findings from this study would suggest that systematic strength training seems to be a beneficial intervention to improve HRQOL, muscle strength and muscle mass in older men.

The impact of home-based high- intensity interval training on physical function in healthy older adults. Full text in Research Archive Show summary

  INTRODUCTION: Resistance training is widely recommended to enhance physical function (PF) in older adults (1). High-velocity resistance training receives particular attention due to the strong link between muscular power and functional movement (2). High-intensity interval training (HIIT) has also shown promise for improving power-related adaptations in older populations (3). As a time-efficient and generally well-tolerated training modality, HIIT offers a viable exercise option for older adults (4). However, its efficacy in enhancing PF among this population remains unclear. Furthermore, the effectiveness of HIIT under free-living conditions as part of broader public health strategies has not been adequately investigated (5). Therefore, the present study aimed to assess the impact of a 6-month home-based HIIT program on PF in healthy older adults. METHOD: Healthy older adults (n=233, aged 60-84, 54% female) from Norway and the UK were randomly assigned to either a HIIT group (mean age±SD: 67.6±5.9yr) or a non-exercising control group (mean age±SD: 67.0±5.2yr). The exercising group participated in a 6-month, thrice weekly HIIT intervention (2 interval and 1 circuit sessions per week). PF measures at pre- and post-intervention included Grip strength, 30-sec-chair-stand, Chair-sit-and-reach, Back scratch, Timed-up-and-go, and One-leg standing. Additionally, PF was calculated as a composite Z-score (PF Z-score) based on all aforementioned tests. General Linear Models were used to assess between-group differences in post-intervention scores for each standardized test and the PF Z-score, with pre-intervention scores, age, sex, and country of residence as covariates, and group as a fixed factor. Effect sizes (ES) were calculated using mean differences (pre-post), pooled standard deviations, and sample sizes for the exercise and control groups. Alpha level of 5% was chosen for statistical significance, with 95% CI presented. RESULTS: Significant between-group differences at post-intervention were observed for PF Z-score (β=0.24, [95%CI: 0.17;0.30] (ES:0.97), Grip-strength (β=1.8 [0.8;2.8] kg (ES:0.48), 30-sec-chair-stand (β=1.3 [0.7; 1.8] repetitions (ES: 0.63), Back scratch (β=2.1 [0.8;3.5] cm (ES:0.43), and Timed-up-and-go (β=−0.3 [−0.4;−0.2] seconds (ES:0.71). No significant between-group differences post-intervention were observed for Chair-sit-and-reach and One-leg standing tests. CONCLUSION: These findings indicate that healthy older adults can enhance their PF through a 6-month home-based HIIT intervention. However, no significant effects were observed in joint flexibility of the lower extremities or static balance ability. Nonetheless, these findings reinforce the potential of HIIT as a valuable component in public health strategies for promoting physical function in healthy older adults. REFERENCES: 1.

  <b>Sammendrag av hovedfunn</b> - Kartleggingen av fysisk form blant voksne og eldre i Norge 2022-23 (Kan3 fase 2) er utført ved Norges idrettshøgskole i samarbeid med Folkehelseinstituttet. Kan3 fase 2 inngår som en del av det nasjonale kartleggingssystemet for fysisk aktivitet og fysisk form der formålet er å følge opp tidligere undersøkelser av voksne og eldre for å øke kunnskapen om status, trender og utviklingen av fysisk form i den norske befolkingen. Datainnsamlingen i Kan3 fase 2 er gjennomført i samarbeid med Universitetet i Stavanger, Universitetet i Agder, UiT Norges arktiske universitet, Høgskulen på Vestlandet og Høgskolen i Innlandet i perioden august 2022 til april 2023.<p> <p>Et tilfeldig utvalg av deltakere som deltok i Kan3 fase 1 (hovedutvalg) ble invitert til fysisk oppmøte for gjennomføring av tester for å måle fysisk form i Kan3 fase 2. Som beskrevet i Kan 3 fase 1 rapport ble det også rekruttert deltakere som var 67+ år gjennom egne rekrutteringsstrategier mot seniorsenter i de store byene. Disse deltakerne gjennomførte tester av gripestyrke, balanse og bevegelighet, men de gjennomførte ikke test av maksimalt oksygenopptak.<p> <p>Av totalt 2001 personer som ble invitert, samtykket 1503 personer til deltakelse i Kan3 fase 2. Som vist i Kan 3 fase 1 er utvalget noe selektert da det er forholdsvis flere med høy sosioøkonomisk status i utvalget sammenlignet med den øvrige befolkningen. Den samme selekteringen er følgelig med videre inn i fase 2, og det betyr at beregninger for fysisk form trolig vil være noe overestimert.<p> <p><b>Maksimalt oksygenopptak (VO2max)</b> - Menn hadde høyere maksimalt oksygenopptak enn kvinner i alle aldergrupper. Oksygenopptaket falt med henholdsvis 2.8 ml∙kg-1∙min-1 og 3.9 ml∙kg-1∙min-1 blant kvinner og menn per 10 års økning i alder. Blant både menn og kvinner, hadde den femtedelen av deltakerne med høyest oksygenopptak et oksygenopptak som var omtrent dobbelt så høyt som den femtedelen av deltakerne med lavest oksygenopptak. Deltakere som tilfredsstilte Helsedirektoratets anbefaling for fysisk aktivitet, hadde høyere oksygenopptak sammenlignet med de som ikke tilfredsstilte anbefalingen. Oksygenopptaket økte med høyere utdanningsnivå blant menn, men ikke blant kvinner.<p> <p><b>Gripestyrke, balanse og bevegelighet</b> - Yngre hadde høyere gripestyrke enn eldre, og menn hadde høyere gripestyrke enn kvinner. Balansen reduseres med økende alder og en stor reduksjon sees etter fylte 60 år. Generelt var bevegeligheten i hofte og skulderledd bedre blant kvinner enn menn. For begge kjønn reduseres bevegeligheten med økende alder. Det var ingen sammenheng mellom gripestyrke, balanse og utdanning, men bevegelighet i hofteledd økte med høyere utdanning blant kvinner.<p> <p><b>Trender</b> - Både menn og kvinner i Kan3 fase 2 hadde et høyere maksimalt oksygenopptak enn menn og kvinner som deltok i Kan1 fase 2 i 2008-09. Menn hadde et oksygenopptak som var 2.3 ml∙kg-1∙min-1 (95% KI: 1.1 – 3.4) høyere i Kan3 sammenliknet med i Kan1, og tilsvarende forskjell for kvinner var 2.6 ml∙kg-1∙min-1 (95% KI: 1.6 – 3.5). Dette tilsvarer en prosentuell forskjell mellom Kan1 og Kan3 på 6-7%. Data må dog tolkes med forsiktighet fordi utvalget i Kan 1 er noe ulikt utvalget i Kan 3. Det var ingen forskjeller i gripestyrke når vi sammenlignet deltakere i Kan3 med deltakere i Kan1.<p> <p><b>Praktiske implikasjoner</b> - I gjennomsnitt har deltakere i Kan3 et oksygenopptak som er godt over eller på nivå med foreslåtte internasjonale og nasjonale grenseverdier for anbefalt VO2max. Spredningen i materialet er imidlertid betydelig og for den femtedelen av deltakerne med lavest oksygenopptak ligger verdiene betydelig lavere enn anbefalte verdier, noe som kan gi økt risiko for sykdom og tidlig død. I denne gruppen vil selv dagligdagse aktiviteter, som det å gå i trapper eller å sykle kreve en så stor andel av det maksimale oksygenopptaket at det vil være vanskelig å delta i slike aktiviteter i mer enn noen få minutter. Oksygenopptaket er imidlertid trenbart uansett alder og utgangspunkt. En økning i det maksimale oksygenopptaket hos denne gruppen vil kunne ha stor betydning for å sikre en god fysisk funksjon, det vil si gi økt mestring av dagliglivets aktiviteter.<p> <p>Lav gripestyrke er også assosiert med økt risiko for sykelighet og tidlig død. Selv om muskelmassen og maksimal styrke faller naturlig med økende alder, vil regelmessig styrketrening kunne forebygge mye av dette fallet. Styrketrening er spesielt viktig fra 50–60-årsalderen, og selv personer over 70 år vil kunne øke både muskelmassen og styrken betraktelig ved å starte med regelmessig styrketrening.
