Effects of a Single Bout of Resistance Training Session on Hormonal Response in Pre-pubertal and Pubertal Boys
: Resistance training induces strength gains in both children and adolescents. Exercise training is linked to anabolic functions through the GH-IGF-I axis. This has been demonstrated in studies showing a higher activity of GH and IGF-I in fitter adolescents and adults. Exercise also stimulates pro-inflammatory cytokines (IL-1β, IL-6, TNF-α) that suppress the GH-IGF-I axis. This has been observed in endurance-type training, while resistance training has received less attention.
Boys experience a significant physiological muscle-growth change during puberty that is associated with increases in boys androgen levels. How maturation affects the hormonal response to resistance training in boys is unclear. Therefore, the purpose of the study is to compare the acute effects of a single bout of resistance training on hormones and pro-inflammatory cytokines in pre-pubertal and pubertal boys.

Preliminary measurements:
Preliminary testing will include anthropometric measurements of body mass, height, body fat percentage, and lean leg volume (LLV). The maturation stage will be determined according to the Tanner scale. There will also be an assessment of maximal strength testing to determine exercise intensity for each individual. Two familiarization sessions will be conducted for muscular strength before the muscular strength testing session.
Main trial A venous blood sample will be collected pre-exercise at resting condition. The trial will start with a standardized warm-up followed by a short (20-30 min), high-intensity whole-body resistance training session. Venous blood samples will be collected immediately after the completion of the training session and during the recovery period.
