ANTUNES, R et al. Quality of life, vitality and handgrip strength in elderly practitioners of physical exercise. CPD [online]. 2022, vol.22, n.1, pp.245-255.  Epub 19-Set-2022. ISSN 1989-5879.  https://dx.doi.org/10.6018/cpd.467011.

Ageing is associated with chronic pathologies, which can be prevented or delayed through the involvement in healthy behaviours, such as regular physical exercise (PE). The aims of this study were to characterize the quality of life, vitality and handgrip strength of elderly people, participants in PE community programs, as well as to analyze the relationship of PE practice with these variables. A sample of 81 individuals, 49 females and 32 males, aged between 65 and 85 years (72.33 ± 5.02) were recruited. The results showed that men had higher values in the variables handgrip strength (p<0.001; 2 =0.510), subjective vitality (p=0.05; 2=0.005) and in the “intimacy” domain of quality of life (p=0.01; 2 =0.005). Regarding the analysis of the relationships, in females, handgrip strength is related with the weekly frequency (r=0.42; p=0.003), with the number of practice hours per week (r=0.49; p<0.001), and with general quality of life (r=0.35; p=0.015). Still in females, we verified the existence of a significant linear regression of the weekly frequency of practice (adjusted R2=0.23; p<0.001) and the number of weekly hours (adjusted R2=0.30; p<0.001), with handgrip strength. In males, we verified that handgrip strength is related with the number of hours of weekly practice (r=0.38; p=0.033). Finally, vitality is related with handgrip strength (r=0.49; p=0.004), and general quality of life (r=0.61; p<0.001). Thus, the role of PE practice in this population seems evident, not only for the associated physical, mental, and social benefits but also for the role it appears to play in the perception of quality of life and subjective vitality. Moreover, it still seems essential to include strength training, which appears to be associated with a better perception of quality of life and vitality by the elderly.
