1. Overview

Physical activity is essential for maintaining physical and mental health, preserving thus, functional capacity in older adults. Despite these benefits, physical activity levels tend to decline with age and many older people are considered sedentary or physically inactive. There are several guidelines and recommendations for physical activity in older adults, such as 150 min of moderate-intensity aerobic physical activity or 75 min of vigorous-intensity aerobic physical activity, or an equivalent combination of moderate to vigorous-intensity physical activity per week, but the majority of older adults usually fail to meet the above recommendations (Bauman et al., 2016).
