About this study
Official title: Effects of Training With Proprioceptive Neuromuscular Facilitation on Vertical Jump Performance and Postural Stability in Male Basketball Players
The purpose of this study is to examine the effect of PNF applications on vertical jump performance and postural control in male basketball players.
The hypotheses of this study are:
Read more
H1: PNF applications affect vertical jump performance in male basketball players.
H2: PNF applications have an effect on postural control in male basketball players.
H3: There is no difference between the PNF group and the control group in terms of the effect of PNF applications on vertical jump performance and postural control in male basketball players.
Participants will be included in a 6-week program based on the group they are assigned to in the randomization. Those in the exercise group will perform lower extremity PNF patterns 3 days a week for a total of approximately 20-30 minutes. No intervention will be performed on the control group. Participants' vertical jump performance and postural control will be assessed twice: before and after the intervention.
Read the detailed description
This study is planned as a randomized controlled trial. After obtaining ethical committee approval, the study will be conducted on male basketball players within one year. The population of the study consists of male basketball players. The sample of the study will consist of male professional basketball players aged 18-35 who volunteer to participate in the study. To calculate the sample size of the study, a study (14) using similar methods was considered, and based on the hypothesis that the difference between the two groups would have a medium effect size, a two-way variance analysis was performed using the G*Power Version 3.1.9.2 (Franz Faul, Universitat Kiel, Germany) program. The results indicate an effect size of f=0.41, replication = 2, number of groups = 2, correlation between repeated measures = 0.5, Type I error = 0.05, and statistical power = 0.99. This resulted in a sample size of at least 15 patients per group, totaling 30 patients. Participants will be divided into two groups using the block randomization method: the PNF group and the control group. Block randomization will be performed via https://www.sealedenvelope.com/simple-randomiser/v1/lists.
All participants' demographic information will be collected via a form. Participants will be included in a 6-week program based on the group they are assigned to in the randomization. If they are in the exercise group, they will perform lower extremity PNF patterns 3 days a week for a total of approximately 20-30 minutes. Rhythmic initiation and combined isotonic PNF techniques will be used during training. Two basic PNF techniques will be applied during the training process. Rhythmic initiation is performed by gradually and repeatedly performing the movement pattern using passive, active-assisted, and resistive movement phases to improve movement learning and coordination. Each phase of the movement pattern (passive, active-assisted, resistive) will be performed 3 times, for a total of 1 set. The goal of combined isotonic exercises is to increase muscle activation and improve neuromuscular control throughout the targeted lower extremity movement pattern. During the application, sequential manual resistance is applied at different stages of the movement, and all concentric, isometric, and eccentric contractions are performed in a single fluid movement. Resistance is applied in a controlled manner by the therapist at the beginning, middle, and end of the range of motion. Combined isotonic exercises will be performed with 6-10 repetitions and 3-4 sets, with 60 seconds of rest between sets, by sequentially and fluidly applying concentric-isometric-eccentric contractions under moderate manual resistance throughout the target pattern. All techniques will be applied bilaterally in a controlled, standardized manner appropriate to participant tolerance. No intervention will be applied to the control group. Participants' vertical jump performance and postural control will be assessed twice: before and after the intervention.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Proprioceptive Neuromuscular FacilitationOther
During training, rhythmic initiation and combined isotonic PNF techniques will be applied. Rhythmic initiation will be performed through passive, active-assisted, and resistive phases to facilitate motor learning and coordination, with each phase repeated three times (one set). Combined isotonic exercises aim to enhance muscle activation and neuromuscular control by sequentially applying concentric, isometric, and eccentric contractions within a single continuous movement. Moderate manual resistance will be provided by the therapist at the beginning, middle, and end of the range of motion. Combined isotonic exercises will be performed bilaterally for 6-10 repetitions and 3-4 sets, with 60 seconds of rest between sets, in accordance with participant tolerance.

What is being measured
The primary outcome is the main question the study is designed to answer.
VERTICAL JUMP PERFORMANCE
In the vertical jump test, the difference between the height reached while standing and the height reached while jumping (m) will be taken, and anaerobic power data will be calculated from the Lewis Nomogram together with body weight (kilograms).
Measured: At baseline and from enrollment to the end of treatment at week 6.
POSTURAL CONTROL
Postural control assessment will be performed statically and dynamically using the Biodex Balance System SD (Biodex Medical Systems, Inc., Shirley, NY).
Measured: At baseline and from enrollment to the end of treatment at week 6.
