This study looked at how body composition and metabolism change in men with spinal cord injuries after they stop exercising. Researchers followed men who had participated in exercise trials and compared them to a control group to see if previous exercise affected later measurements. The study found that the positive effects of exercise, like increased muscle mass, faded after about 2.5 years of stopping the exercise program.
A 2.5-year gap is sufficient to washout the effects of previous exercise interventions on subsequent clinical trials.
Continuous exercise interventions are needed to ensure long-term compliance and avoid loss of lean mass and increased fat mass with aging.
Following an exercise routine, reduced exercise frequency (e.g., once a week) may maintain gains in body composition and metabolic profiles.
