endurance exercise, endurance exercise [Exercise-induced dehydration
EVENTS
The rate of participation by masters class athletes (MCAs) in organized endurance and ultra-endurance events (>6 hours) has increased exponentially over the past 10–15 years [Two different isoenergetic options have been shown to effectively promote glycogen resynthesis post-exercise: CHO (1.2 g/kg) and CHO-P (0.8 g/kg CHO + 0.4 g/kg PRO) [Masters class endurance athletes frequently train in the evening and the next morning, on successive weekend days, or twice per day one-to-two times per week when preparing for a triathlon. A high weekly training volume combined with the demands of family and professional responsibilities is a considerable time investment [Protein intake promotes skeletal muscle remodeling and repair, adaptation to training, and replenishment of energy stores [A post-exercise and (daily) per meal intake of 0.40 g/kg of protein or approximately 30 g has been recommended by others to promote the repair and remodeling of skeletal muscle in master athletes who regularly engage in endurance exercise [Exercise-induced dehydration can impair thermoregulation and promote cardiovascular strain during a bout of prolonged endurance exercise [While there is an increased rate of participation by MCAs in endurance sports, a critical gap in the research exists related to post-exercise nutrition specific to MCAs and short-term (2 hours or less) recovery. This is problematic as slower recovery rates between subsequent bouts of exercise have been demonstrated, and higher protein needs post-exercise have been indicated to promote muscle remodeling and repair in MCAs [
