Traditional set (TS) and drop set (DS) training modalities differentially affect muscle fatigue and proprioception. Excessive fatigue may compromise proprioceptive function, thereby increasing injury susceptibility. Comparative analysis of TS and DS effects can facilitate training optimization for enhanced performance and safety.
Objective
This study aimed to compare the acute effects of traditional set and drop set training methodologies on fatigue levels and proprioceptive sensory mechanisms in bodybuilders.
Methods
Twenty-eight male bodybuilders (mean age: 25.53 ± 2.68 years) were randomly allocated to two groups: traditional set (TS, n = 14) and drop set (DS, n = 14). Fatigue was assessed using myotonometric measurements of the pectoralis major (PM), triceps brachii (TB), and deltoid (D) muscles, while proprioceptive accuracy was evaluated using a laser-based angle replication test for shoulder flexion (SF), shoulder abduction (SA), elbow flexion (EF), and wrist flexion (WF).
Results
Both training methodologies induced muscle fatigue and compromised proprioception; however, the deleterious effects of traditional sets were more pronounced. The results demonstrated that the TS group exhibited greater fatigue and more substantial proprioceptive disruption compared to the DS group in the following parameters: PM (u = −1.956; d = 0.84; p = 0.05), TB (t = 2.237; d = 0.84; p = 0.034), SF (t = 2.577; d = 0.97; p = 0.016), EF (u = −1.562; d = 0.68; p = 0.118), and WF (u = −3.033; d = 1.07; p = 0.002) (p < 0.05).
Conclusion
Drop set training may represent a more efficacious method for reducing fatigue while maintaining proprioceptive accuracy, constituting a suitable approach for athletes and coaches seeking to optimize performance and minimize injury risk.
