A comparative analysis of the impact of two resistance training loading protocols, combined with Tribulus supplementation, on hormonal responses and muscle strength in young athletes.

Examine the impact of two resistance training protocols along with supplementation, on testosterone, cortisol, lipid profiles, and maximal strength of young athletes.

This research involves a clinical trial design that includes four groups, with each group comprising a sample of 12 participants.

The performance assessment takes place in a gym setting utilizing fitness equipment, while blood tests are conducted in a laboratory. Blood samples are collected in a fasting state prior to the initiation of training and supplement consumption, with a follow-up measurement occurring after an 8-week period.

A group of 48 male volunteers, aged between 25 and 45, will be selected to participate in this study. To qualify for inclusion, participants must have consistently engaged in physical activity over the past year, must be free from musculoskeletal injuries or particular medical conditions, and must not be using any other dietary supplements. On the other hand, the exclusion criteria include voluntary withdrawal from the study, the development of physical injuries or specific illnesses, and the absence from more than three sessions of the exercise interventions.

Participants will be randomly assigned to one of four experimental groups. Each group will consist of 12 individuals, totaling 48 participants. The groups will include: one focused on strength training at 70% of maximum strength to failure, another utilizing pyramid loading for strength training, a third group engaging in strength training at 70% of maximum strength while receiving supplements, and a fourth group combining pyramid loading with supplements.
