Effects of aging and resistance training in rat tendon remodeling.

In elderly persons, weak tendons contribute to functional limitations, injuries, and disability, but resistance training can attenuate this age-related decline. We evaluated the effects of resistance training on the extracellular matrix (ECM) of the calcaneal tendon (CT) in young and old rats and its effect on tendon remodeling. Wistar rats aged 3 mo (young, = 30) and 20 mo (old, = 30) were divided into 4 groups: young sedentary, young trained, old sedentary (OS), and old trained (OT).

Serious game development as a strategy for health promotion and tackling childhood obesity.

Objectives: to develop and assess a serious game on healthy eating and physical activity to promote health and tackle childhood obesity.

Method: a descriptive, applied and methodological study.For the development of the game, the following steps were taken: conceptualization, pre-production with the development of the game documentation, prototyping, production and assessment of thecomputer and health experts.
