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.
This is the only study on the registry with Ramazan Erdoğan as lead sponsor.

Exclusion Criteria:
Participants performed a structured powerlifting-based training program in addition to their regular basketball training. The intervention was conducted three days per week for six weeks. Each session lasted approximately 60 minutes and included a standardized warm-up, a powerlifting-focused main training phase, and a cool-down period. The training program emphasized the squat, bench press, and deadlift exercises performed with progressive intensity. Accessory exercises targeting lower-body strength, upper-body musculature, and core stability were included. High-intensity bodyweight exercises were also performed to enhance anaerobic capacity and neuromuscular performance. All training sessions were supervised by qualified staff.
Other: Powerlifting-Based Training · Other: Blood Sampling and Laboratory Analysis
Participants continued their usual basketball training routines throughout the study period without any additional strength or powerlifting-based exercises.
Other: Usual Basketball Training · Other: Blood Sampling and Laboratory Analysis
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.
Participants continued their usual basketball training routines without any additional strength or powerlifting-based exercises.
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.
