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.

Outcome Measures

Primary Outcomes (1)

• T agility test

  The T agility test is used to assess an athletes agility and ability to change direction quickly. The test is set up with four cones arranged in a T shape. The athlete starts at the base of the T and sprints forward to the second cone, then turns right and runs to the right cone, touching it. Next, they run to the left cone and touch it, return to the middle cone, and finally sprint back to the starting point. The time is recorded with a stopwatch, starting when the athlete begins and stopping when they return to the starting point. Lower times indicate better agility performance.

  Immediately before and after the stretching intervention, assessed within a single session, approximately 30 minutes in total

Secondary Outcomes (3)

• 30-meter sprint test

  Immediately before and after the stretching intervention, assessed within a single session, approximately 30 minutes in total

• Lateral long jump test

  Immediately before and after the stretching intervention, assessed within a single session, approximately 30 minutes in total

• Standing long jump test

  Immediately before and after the stretching intervention, assessed within a single session, approximately 30 minutes in total

Study Arms (2)

Passive Group

EXPERIMENTAL

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

Other: Passive stretching

PNF group

EXPERIMENTAL

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.

Other: PNF stretching

Interventions

Passive stretching 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.

Passive Group

PNF stretching 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.
