Understanding how resistance training affects muscle growth and fitness

Towards Personalized Exercise: Identifying the Determinants of Individual Variation in Repeated Resistance Training (TraDeRe) and Examining Transferability of Responsiveness Between Resistance Training and Endurance Training

Not applicable Interventional University of Jyvaskyla · NCT06573086

This study is testing how resistance training affects muscle growth and fitness in healthy people to see what factors might help them get better results.

What this trial studies

This research project aims to explore the reasons behind the varying responses individuals have to resistance training (RT) and how these responses may predict outcomes in endurance training (ET). By examining physiological, cellular, and molecular mechanisms, the study will investigate how different factors influence muscle growth and adaptation to exercise. A total of 362 healthy participants will undergo a 12-week RT program, with their responses monitored to identify predictors of training success and the impact of environmental factors such as nutrition and sleep.

Who should consider this trial

Good fit: Ideal candidates for this study are healthy adults aged 18-50 who have previously participated in a related intervention.

Not a fit: Patients with metabolic, musculoskeletal, cardiovascular disorders, or those on medications affecting exercise performance may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to personalized exercise programs that optimize training outcomes for individuals based on their unique responses to resistance training.

How similar studies have performed: While there have been studies on resistance training responses, this multi-OMIC approach to understanding variability in responses is relatively novel and underexplored.
