简要总结
The purpose of this randomized controlled trial is to compare the acute effects of static stretching, dynamic stretching, and proprioceptive exercises on proprioception, muscle strength, balance, and explosive power in young athletes. The study aims to determine how different stretching and exercise modalities influence short-term performance parameters.
The primary questions this study aims to answer are:
Do static stretching, dynamic stretching, and proprioceptive exercises have different acute effects on proprioception?
Do these interventions cause different changes in muscle strength, balance, and explosive power?
Researchers will compare the static stretching, dynamic stretching, and proprioceptive exercise groups to determine which method produces greater improvements in the measured performance parameters.
Participants will:
Perform one of the three assigned exercise protocols according to a standardized warm-up procedure
Undergo pre- and post-exercise assessments, including:
Proprioception (measured with an isokinetic device)
Muscle strength (measured with an isokinetic device)
Balance (measured with a Y balance test and BESS balance test)
Explosive power (measured with the Sargent Vertical Jump Test)
详细描述
This randomized controlled trial aims to compare the acute effects of static stretching, dynamic stretching, and proprioceptive exercises on knee joint position sense (proprioception), muscle strength, balance, and explosive power in young male soccer players.
Proprioception, the ability to sense the position and movement of joints, muscles, and tendons, plays a critical role in maintaining joint stability. Proprioceptive exercises are widely used among athletes to enhance performance and reduce injury risk. Stretching exercises, particularly static and dynamic techniques, are commonly integrated into warm-up routines to improve flexibility, joint range of motion, and neuromuscular function. However, direct comparisons of the acute effects of static stretching, dynamic stretching, and proprioceptive exercises remain limited.
In this study, healthy male soccer players aged 14-19 years, with at least five years of competitive experience, no knee pain in the past two months, and no history of knee surgery, will be included. Participants will be randomly assigned (block randomization) into three groups:
Static Stretching Group - A controlled-position protocol targeting the quadriceps, hamstrings, plantar flexors, and dorsiflexors, with specific hold durations.
Dynamic Stretching Group - A repetitive movement protocol for the same muscle groups, with gradual speed increases.
