Effects of Powerlifting-Based Training in Athletes

Ramazan Erdoğan30 enrolled

Overview

This randomized controlled trial aims to examine the effects of a weightlifting-based training program on hormonal, metabolic, and lipid profile parameters in athletes. Participants will be randomly assigned to either a weightlifting-based training group or a control group. The training program will be implemented for a specific period, and relevant blood parameters will be evaluated before and after the intervention. The findings of this study may contribute to a better understanding of the physiological effects of weightlifting-based training on athletes.

This study is designed as a randomized controlled trial to investigate the effects of a structured weightlifting training program on hormonal, metabolic, and lipid profile parameters in athletes. Eligible participants will be randomly assigned to either an intervention group undergoing a weightlifting-based training protocol or a control group continuing their usual training routines. The intervention will be implemented over a predetermined training period, and outcome measures will include selected hormonal, metabolic, and lipid profile markers obtained from blood samples. Measurements will be taken at baseline and at the end of the training period. The results of this study are expected to provide evidence on physiological adaptations associated with weightlifting-based training and offer practical implications for training program design in athletic populations.

Interventions

Powerlifting-Based TrainingOTHER

Participants will perform a structured powerlifting-based training program including squat, bench press, and deadlift exercises, conducted 3 sessions per week for 8 weeks under supervision.

Usual Basketball TrainingOTHER

Participants continued their usual basketball training routines without any additional strength or powerlifting-based exercises.

Blood Sampling and Laboratory AnalysisOTHER

Venous blood samples were collected from participants at baseline and post-intervention following an overnight fast. Hormonal parameters were analyzed using ELISA methods, and metabolic and lipid profile parameters were analyzed using an automated biochemical analyzer.
