Gender, exercise, and health: A life-course cross-sectional study.

The purpose of this study is to explore relationships between the practice of exercise, gender, and health, from adolescence to old age, testing the magnitude of gender differences throughout the life cycle in the practice of exercise of Spanish people. A cross-sectional study with 4,575 women and 4,334 men, aged 13-85 years, was conducted. The participants were assessed on the weekly hours they dedicated to the practice of exercise, masculine/instrumental and feminine/expressive traits, mental health symptomatology, and self-rated health). Univariate and multivariate analyses were performed in the age groups of adolescence, late adolescence, young adulthood, middle adulthood, and older age. Results showed that men dedicated significantly more hours to the practice of exercise than women within all age groups, except in older age (men´s average = 4.07; women´s average = 2.55). The masculine/instrumental trait played a mediating role between gender and practice of exercise hours. Furthermore, a decline in the amount of time dedicated to exercise from adolescence to older age was found, with higher drops in men. Finally, the practice of exercise was associated with better self-rated health and less mental symptoms. These results underline the important role that gender and masculine-instrumental trait play on the practice of exercise .
