The study aimed to evaluate the biological age of middle-aged individuals engaged in hardening practices, focusing on differences based on gender and additional sports activities.
It involved 63 participants (36 women and 27 men), using bioimpedance analysis to assess body composition and determine biological age through established methods.
Results indicated that participants had a higher body mass index than normal, but those involved in hardening showed a lower biological age compared to their calendar age, suggesting that hardening may positively impact physiological health and aging.
