Purpose: The present study examined the influence of endurance training on the morphological and functional heart adaptations in young athletes throughout a longitudinal 9-month follow-up period during the adolescent peak height velocity (PHV).
Methods: Thirty-six 13- to 15-year-old males (twenty-three triathletes and thirteen untrained peers) were evaluated before and after a 9-month period during PHV. Maximal oxygen uptake ( ) and power at were assessed during incremental cycling test.
Article Synopsis
- Prolonged strenuous exercise can temporarily impair cardiac function and lead to pulmonary issues like bronchoconstriction, dynamic hyperinflation, and reduced gas exchange capacity.
- The study assessed 60 male triathletes before and after a long-distance race to compare cardiac function in those with and without exercise-induced pulmonary dysfunctions.
- Post-race findings showed declines in both systolic and diastolic functions across all groups, but those with diffusion impairment had more significant decreases in cardiac work and specific heart metrics.
Even if more and more women are involved in strength-training (ST) programs in fitness centers, studies on strength gain, body composition, and cardiac remodeling were mainly conducted in men and whether they are similar in women remains to be explored. In this context, the aim of our study was to assess the effect of a supervised ST program on strength gains, body composition, and cardiac remodeling in previously untrained women and men. 17 healthy and previously untrained young women and 17 young men participated in a supervised 16-week ST program built according to the recommendation of the American College of Sports Medicine in terms of intensity, and strictly using similar volume and intensity in both groups.

However, whether endurance training triggers further neuromuscular adaptations exceeding those of growth and maturation alone over the rapid adolescent growth period is yet to be determined.
Objective: The present study investigated the concurrent role of growth, maturation, and endurance training on neuromuscular function through a 9-month training period in adolescent triathletes.
Article Synopsis
- - Early differences in neuromuscular function were found between strength-trained (wrestling) and endurance-trained (triathlon) adolescent athletes, highlighting that such variations can emerge by early adolescence.
- - The study involved 23 triathletes, 12 wrestlers, and 12 untrained male adolescents, measuring knee extensor torque and muscle activation through various techniques like isometric contraction and EMG.
- - Results indicated that wrestlers had higher knee extensor torque and specific muscle architectural advantages compared to triathletes and untrained individuals, suggesting that strength training could lead to distinct neuromuscular characteristics even in young athletes.
