Dynamic vs. PNF Quadriceps Stretching in Cyclists

Comparison of the Effects of Dynamic and PNF Stretching Applied to the Quadriceps Muscle Group on Muscle Performance, Muscle Strength, and Joint Range of Motion in Professional Cyclists

Following an initial assessment, 30 professional cyclists will be divided into two groups (1:1). PNF stretching will be applied to the Quadriceps muscles of the participants in Group A, while Group B will perform dynamic stretching on the Quadriceps muscles. After the interventions, all participants will undergo a second assessment. The study aims to compare the immediate effects of these two different types of stretching on muscle performance, strength and joint range of motion. Participants will attend a single day for both the assessments and the intervention sessions.
