“…The grouping of these variables to classify people based on the observation of similarities and dissimilarities concerning sarcopenia thus proved to be different for men and women. Gait slowness was more prevalent in women than men, while muscle weakness was more prevalent in men in our sample [ 28 ]. These observations may be due to a lower gait speed in women and a more significant age-related decline in muscle mass/strength in men [ 29 ].…”

Background There are several markers for the suspicion, identification, and confirmation of sarcopenia. Objectives To analyse the importance of several markers for assessing sarcopenia by classifying phenotypes based on five domains: symptomatology, muscle function, muscle mass, physical performance, and physical function. Methods A cross-sectional study analysing 312 older adults (72.6±7.8 yrs) was conducted in Novo Aripuanã, Amazonas, Brazil. Symptoms of sarcopenia were determined with the SARC-Calf; muscle function was assessed using the 30-Chair Stand test (CST), 30-CST power, and handgrip strength (HGS) with and without normalisation for body mass/height; the skeletal muscle mass index (SMMI) was estimated from anthropometry; physical performance was determined through the 4-m gait speed (GS) and 6-min walking test (6MWT); and physical function was determined with the Composite Physical Function Scale (CPF). Results Cluster analysis revealed two phenotypes (at risk vs not at risk for sarcopenia) and the contribution of each marker (ranged from 0 to 1). In men, the contribution of each marker was: 1 for SARC-Calf, 0.18 for SMMI, 0.09 for 30-CST power and 0.06 for HGS; in women: 1 for SARC-Calf, 0.25 for 30-CST power, 0.22 for SMMI, 0.06 for GS, 0.04 for HGS, and 0.03 for CPF. Considering the cutoff values proposed by Rikli and Jones (2013) for physical function and Cruz-Jentoft et al. (2019) for the other domains, the risk profile for sarcopenia was characterized by: high SARC-Calf in both sexes (men:51.8 vs 3.6%, p<0.001; women:71.2 vs 1.1%, p<0.001), low SMMI (men:73.2 vs 44.6%, p<0.002; women:44.1 vs 23.6%, p = 0.002); in women, low GS (38.7 vs 12.4%, p<0.001) and low CPF (29.7 vs 15.7%, p = 0.020), and no differences in HGS between groups in both sexes. Conclusions SARC-Calf, SMMI, and 30-CST were more relevant markers for sarcopenia risk in older adults of both sexes, GS and CPF played also an important role in women.

Exploring individuals’ patterns of physical activity and sedentary behaviour can reveal profiles that could differently impact health outcomes and benefit targeted interventions. This study aimed to identify latent profiles of physical behaviour in older adults and examine their association with physical fitness and function outcomes. The sample included 1095 participants (765 females) from the Portuguese physical activity and sports monitoring system. Latent profiles of physical behaviour were identified based on the percentage of waking time spent in sedentary behaviour, light physical activity, and moderate-to-vigorous physical activity (MVPA) assessed by accelerometery. Physical fitness was assessed by Senior Fitness Test Battery, and physical function was evaluated through the 12-item Composite Physical Function questionnaire. Associations between the profiles of physical behaviour and physical fitness and function outcomes were examined using generalized linear models adjusted for age. Three profiles of physical behaviour were identified: "active", "intermediate", and "sedentary" for both sexes. Participants with “active" or "intermediate" profiles exhibited the most favourable physical fitness and functional outcomes, while those with a "sedentary" profile showed the poorest results. Our findings suggest that a more balanced behaviour between physical activity and sedentary behaviour throughout the waking day appears to provide physical fitness and functional benefits, even if MVPA are not fully met. This is important for older adults who may struggle to comply fully with MVPA guidelines but could maintain or improve their physical fitness and function with a more active behaviour through the reduction of sedentary behaviour and inclusion of light physical activity.
