“…For MVPA, we observed a slightly higher correlation between objective and self-reported measures (r=0.25, p<0.05), yet it is still lower than previous finding showing that the CHAMPS questionnaire was moderately correlated with the objective SenseWear Armband (rho=0.42, p=0.002). 45 In SOMMA, the objective measure classified more time spent in MVPA than by self-reported. Conversely to self-reported, the objective measure showed longer time in MVPA in women than men.…”

BackgroundSkeletal muscle energetics decline with age, and physical activity (PA) has been shown to counteract these declines in older adults. Yet, many studies were based on self-reported PA or structured exercise interventions. We examined the associations of objective daily PA and sedentary behavior (SB) with skeletal muscle energetics and also compared with self-reported PA and SB. We also explored the extent to which PA would attenuate the associations of age with muscle energetics.MethodsAmong the Study of Muscle, Mobility and Aging (SOMMA) enrolled older adults, 810 (mean age=76±5, 58% women) had maximal muscle oxidative capacity measuredex vivovia high-resolution respirometry of permeabilized myofibers (maxOXPHOS) andin vivoby31Phosphorus magnetic resonance spectroscopy (ATPmax). Objective PA was measured using the wrist-worn ActiGraph GT9X over 7-days to capture sedentary behavior (SB), light, and moderate-to-vigorous PA (MVPA). Self-reported SB, MVPA, and all exercise-related PA were assessed with The Community Healthy Activities Model Program for Seniors questionnaire. Linear regression models with progressive covariate adjustments evaluated the associations between SB, PA and muscle energetics, and the attenuation of the age / muscle energetic association by PA.ResultsEvery 30 minutes more objective MVPA was associated with 0.65 pmol/s*mg higher maxOXPHOS and 0.012 mM/sec higher ATPmax, after adjustment for age, site/technician and sex. More time spent in objective light+MVPA was significantly associated with higher ATPmax, but not maxOXPHOS. In contrast, every 30 minutes spent in objective SB was associated with 0.43 pmol/s*mg lower maxOXPHOS and 0.004 mM/sec lower ATPmax. Only associations with ATPmaxheld after further adjusting for socioeconomic status, body mass index, lifestyle factors and multimorbidities. Self-reported MVPA and all exercise-related activities, but not SB, yielded similar associations with maxOXPHOS and ATPmax. Lastly, age was only significantly associated with muscle energetics in men. Adjusting for objective time spent in MVPA attenuated the age association with ATPmaxby nearly 60% in men.ConclusionMore time spent in daily PA, especially MVPA, were associated with higher muscle energetics. Interventions that increase higher intensity activity might offer potential therapeutic interventions to slow the age-related decline in muscle energetics. Our work also emphasizes the importance of taking PA into consideration when evaluating associations related to skeletal muscle energetics.

“…For MVPA, we observed a lower correlation between ActiGraph and CHAMPS ( r = 0.25, p < 0.05) than a previous study that used the SenseWear Armband ( ρ = 0.42, p = 0.002). 46 In SOMMA, the ActiGraph classified much more time spent in MVPA than did the CHAMPS questionnaire. Such differences could be driven by either the finite list of MVPA-related activities included in the CHAMPS questionnaire, or a potential misclassification of light activity as MVPA when the Montoye et al 29 cut points were applied to the ActiGraph data.…”

Association between physical activity and physical and functional performance in non-institutionalized Mexican older adults: a cohort study

Background Aging is an independent risk factor for deterioration in functional capacity. Some studies have reported that physical activity (PA) improves functional capacity and physical performance among older adults (OA). Thus the objective of the present study was to assess the longitudinal association between PA and functional and physical performance in non-institutionalized OA. Methods A longitudinal analysis using data from the Frailty, Dynapenia and Sarcopenia in Mexican adults (FRADYSMEX, by its Spanish acronym) cohort study was conducted. PA was assessed through the Community Healthy Activities Model Program for Seniors (CHAMPS) instrument. Functionality was measured with the Barthel index and the Lawton and Brody scale, while physical performance was measured with the Short Physical Performance Battery (SPPB). To evaluate the association between the level of PA and physical and functional performance as a continuous variable, a linear regression of mixed effects was performed. To assess PA and dependence in basic activities of the daily life (BADL), instrumental activities of the daily life (IADL), and low physical performance (PP), generalized estimation equation models [to compute odds ratios (OR) and 95% confidence intervals (95%CI)] were computed. Results Older people who performed moderate to vigorous-intensity PA had a lower risk of dependence in IADL (OR = 0.17; 95%CI: 0.10, 0.80) and lower risk of low PP (OR = 0.18; 95%CI: 0.11, 0.58) compared to those in lower categories of PA. Conclusions Older adults living in the community who perform PA of moderate to vigorous intensity have a lower risk of dependence in BADL and IADL and have a lower risk of low PP.
