Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The main objective of this study is to investigate training-induced adaptations in Biceps femoris long head (BFlh) architecture and performance measures such as muscle strength, jumping, and power variables after following 6 weeks of resistance training program with gravitational or inertial hip extension (HE) exercise and a subsequent detraining period, comparing those adaptations with a control group. In addition, this study aims to determine the time course of BFlh architectural adaptations throughout a 6-week training intervention.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Inertial

Hip extension exercise performed under inertial loading conditions using the EPTE Inertial Concept (Ionclinics SL, L'Alcudia, Spain) during six weeks with two sessions per week. The EPTE Inertial Concept is an inertial device that combines a series of output pulleys and telescopic arms, capable of implementing 6 disks of different weights and radii.
