LEITE, Leni Everson Araújo et al. Comparative study of anthropometric and body composition variables, and functionality between elderly that perform regular or irregular physical activity. Rev. bras. geriatr. gerontol. [online]. 2014, vol.17, n.1, pp.27-37. ISSN 1809-9823.  https://doi.org/10.1590/S1809-98232014000100004.

Background:

The impact of regular and irregular physical activity in body composition, muscle mass and strength of the elderly is not well studied yet.

Objective:

To compare anthropometric variables, muscle and fat thickness, mobility, handgrip and lower limb strength between regularly and irregularly active elderly classified by the International Physical Questionnaire Activity Questionnaire.

Methods:

A cross-sectional study conducted with 75 elderly people (14 males and 61 females) who practiced regular (RPA=10) or irregular physical activity (IPA=65). Anthropometric variables (body mass index, circumferences and skinfolds), muscular and fat thickness (triceps, vastus lateralis and medial gastrocnemius [ultrasound]), handgrip strength (Crown dynamometer), lower limb strength (sit and stand up test) and mobility were collected from the sample. Physical activity was assessed by the International Physical Questionnaire Activity Questionnaire.

Results:

No significant differences were found in the anthropometric, skeletal muscle and fat mass and force variables between two groups (p>0.05). However, elders who practiced irregular physical activity presented best performance in the time up and go test than those who practiced regular physical activity (p=0.008). Results were independent of sex and age of subjects (p=0.017).

Conclusion:

The study showed no significant differences between elderly that performed physical activity in regular or irregular way in relation body composition and force parameters. However, the results suggest that even irregular physical activity can help the elderly individuals in the mobility, and prevent falls.
