Summary

To compare the acute effects of traditional and drop set training methods on fatigue levels and proprioceptive sensory mechanisms in bodybuilding athletes.

Detailed description

A total of 28 male bodybuilding athletes with an average age of 25.53 years from Giresun and Ordu provinces participated in the study voluntarily. The participants were randomly divided into two groups as traditional training group (GS) (n=14) and drop set training group (DS) (n=14). Borg CR10 Scale and myotonometric measurements (Myoton Pro muscle palpation device) were used to assess fatigue. Myotonometric measurements were performed on the pectoralis major, triceps brachii and deltoideus muscles. Proprioception characteristics were evaluated in four parameters: shoulder flexion, shoulder abduction, elbow flexion and wrist flexion using laser cursor-assisted angle repetition test. After the application, fatigue levels in pectoralis major, triceps brachii, Borg CR10 parameters and proprioception errors in shoulder flexion, elbow flexion, wrist flexion parameters were significantly higher in the traditional set group compared to the drop set group.

Conditions

• Fatigue Intensity
• Proprioception

Interventions

Type	Name	Description
OTHER	Proprioception Measurements	Laser cursor-assisted angle repetition test was used for proprioception assessment. A coordinate plane with different movement angles was fixed on a wall and the person was positioned 1 meter from this wall. The laser pointer was fixed on the person's arm for shoulder proprioception measurement, 5 cm above the elbow to avoid being affected by other joints, 5 cm above the person's wrist for elbow joint proprioception and fixed on the person's second metatarsal bone for wrist proprioception.
OTHER	Fatigue Measurement	Myoton PRO® (Myoton AS, Tallinn, Estonia) muscle palpation device was used to assess fatigue, and the dynamic stiffness parameter was taken as the basis. The stiffness value is calculated as the maximum acceleration (N/m) of oscillation and deformation in the tissue sensed by the transducer (Chen et al., 2017). The increase in muscle dynamic stiffness has been associated with fatigue level (Klich et al., 2019; Shitova et al., 2020; Wang, 2017). Before the measurement, the athletes' pectoralis major, deltoideus and triceps brachii muscle reference points were determined and marked, and measurements were taken over these points. The athletes were asked to keep their muscles relaxed throughout the measurement in order not to affect the tissue stiffness and the application was performed at room temperature.
