Training and Body Composition during Preparation for a 48-Hour Ultra-Marathon Race: A Case Study of a Master Athlete Although the acute effects of ultra-endurance loads on the body composition were well examined, limited information about the chronic adjustments of the body composition to the ultra-endurance workout. The aim of the present study was to investigate the variations of training and body composition of an athlete during the preparation of a 48-hour ultra-marathon. For all training units (n = 73) before the race, running track, duration and tempo were recorded and body mass, body fat (BF), body water (%), visceral fat, fat-free mass (FFM) were four sizes (waist, upper arm, thighs and wade)and eight skin folds (chest, middle armpit, triceps, scapula, abdomen, beckenbamm, thigh and calf) measured in a 53-year ultra-endurance athlete. The main results of this study were that the athlete’s training plan followed a periodic pattern with respect to the training intensity and the training volume, which increased significantly with time, weight and body fat during the first 30 training units, and the sizes and skin folds were reflected in the respective decrease in theBody fat against. The results of this case study delivered useful information about the variation of the training and body composition during the preparation of an ultramarathon run in a male master ultramarathon runner.
The preparation for an ultra-long-distance race seems to trigger pronounced changes in the body mass and body composition. The case report can be found under https://www.mdpi.com/1660-4601/16/6/903
