Brief Summary

The aim of this clinical trial is to learn the acute effects of passive stretching and proprioceptive neuromuscular facilitation (PNF) stretching techniques on agility, speed and lower extremity explosive strength in young basketball players. It will also provide information about the comparison of two different stretching techniques. The main questions it aims to answer are:

Does passive stretching have positive acute effects on agility, speed and lower extremity explosive strength? Does PNF stretching have positive acute effects on agility, speed and lower extremity explosive strength? The acute effects of passive stretching and PNF stretching on agility, speed and lower extremity explosive strength will be compared.

Participants:

First tests were performed after the same warm-up program. Then, one of the two different stretching techniques was applied and the same tests were repeated immediately afterwards.

Detailed Description

The aim of this study was to examine the acute effects of static passive and proprioceptive neuromuscular facilitation (PNF) stretching techniques on agility, speed and lower extremity explosive power in youth basketball players. Twenty male basketball players were randomized as passive and PNF groups. A single session of technique was applied to each group. Outcome measurements consisted of the T Agility Test, 30-Meter Sprint Test, Standing Long Jump Test, and Lateral Jump Test.

Study Groups

Passive Group

Passive stretching was administered to the hamstring, quadriceps, and calf muscles by the same physiotherapist for participants in the passive group.

Group Type: EXPERIMENTAL

Passive stretching

Intervention Type: OTHER

The physiotherapist positioned each muscle in its maximum lengthened state and held it there for 30 seconds. This process was repeated three times, with a 30-second rest interval between each stretch of the different muscle groups.

PNF group

The "hold-relax" technique, a specialized method within PNF (Proprioceptive Neuromuscular Facilitation), was applied by the same physiotherapist to the hamstring, quadriceps, and calf muscles of the participants in the PNF group.

Group Type: EXPERIMENTAL

PNF stretching

Intervention Type: OTHER

The physiotherapist initially positioned each muscle in its most extended state, similar to the positions used in passive stretching. In this extended position, the participants performed an isometric contraction against maximal resistance in the antagonist direction for 5-8 seconds. Following the isometric contraction, participants were instructed to actively relax, and after a 5-second waiting period to ensure complete relaxation, the movement range was passively increased. The new end point of the extended range of motion was held for 30 seconds. This stretching protocol was repeated three times for each muscle group, with a 30-second rest period between each stretch.
