Does fitness attenuate the relationship between changes in sitting time and health-related quality of life over time in community-dwelling older adults? Evidence from the EXERNET multicenter longitudinal study.

Objective: To assess the relationship between fitness levels and components, sitting time and health-related quality of life (HRQoL), over time among community-dwelling older adults.

Methods: Three different sitting trajectories were calculated: (i) no change; (ii) decrease; and (iii) increase in ST, between baseline and follow-up. Fitness was assessed using the aerobic capacity, upper and lower limb strength, and total fitness.

Rehydration during exercise prevents the increase of homocysteine concentrations.

This study aimed to assess the effect of rehydration during and after acute aerobic submaximal exercise on total homocysteine (tHcy) concentrations and related parameters in physically active adult males. Twenty trained males (29.4 ± 7.

What do we know about homocysteine and exercise? A review from the literature.

High total homocysteine (tHcy) concentrations contribute to an increased risk of cardiovascular diseases and neurodegenerative disorders. Several investigations have focused on the effect of exercise on tHcy concentrations, but results remain controversial. The differences among the methodologies in the investigations make difficult the interpretation of results.
