This is why the popularized proprioceptive neuromuscular facilitation (PNF) exercises are essential.<br> <strong>Objectives. </strong>This study investigated the effects of 6-week PNF stretching exercises on futsal players&#39; balance, circulatory parameters, and motoric adaptations.<br> <strong>Methods. </strong>A total of 36 volunteer futsal players aged 14-17 years who regularly participated in futsal training and did not have any chronic diseases were included in the study. Futsal players were randomly divided into three groups: PNF group (n=12), training group (n=12), and control group (n=12). The PNF group received a PNF stretching exercise program three days a week for six weeks in combination with futsal training. The training group only continued futsal training regularly. No training program was applied to the control group. Age, height, weight, pulse rate, blood pressure, saturation, balance, push-ups, sit-ups, vertical jumps, horizontal jumps, sit-stand flexibility test, and 30-meter sprint test were measured in all groups.<br> <strong>Results. </strong>According to the findings obtained from the study, there was a significant difference (p<0.05) in favor of the experimental groups in systolic blood pressure (p=0.017), push-ups (p<0.001), sit-ups (p<0.001), vertical and horizontal jump (p<0.001) and 30-meter sprint test (p<0.001) in PNF and training groups. While there was no statistical significance between the pre-test and post-test measurements of circulatory parameters in the PNF group, significance was found in favor of the PNF group in the intergroup comparison.<br> <strong>Conclusion. </strong>When measured parameters are evaluated, we can say that PNF exercises applied to futsal players may have positive effects.</div> Proprioceptive Neuromuscular Facilitation, Circulatory, Motor Adaptation, Stretching Exercises, Futsal Players 0 0 http://aassjournal.com/browse.php?a_code=A-11-2335-2&slc_lang=en&sid=1 Mustafa Ceyran mustafaceyrann@hotmail.com 100319475328460015241 0009-0002-5330-7252 No Department of Physical Education and Sports, Gaziantep University, Gaziantep, Turkey Zarife Pancar zarifepancar@gantep.edu.tr 100319475328460015242 100319475328460015242 Yes Department of Physical Education and Sports, Faculty of Sport Sciences, Gaziantep University, Gaziantep, Turkey Mustafa Sencer Ulema m.sencerulema@yyu.edu.tr 100319475328460015243 100319475328460015243 No Department of Physical Education and Sports, Gaziantep University, Gaziantep, Turkey Burak Karaca burakkaracapt@gmail.com 100319475328460015244 100319475328460015244 No Department of Physical Education and Sports, Gaziantep University, Gaziantep, Turkey Ali Muhittin Tasdogan drmtasdogan@gmail.com 100319475328460015245 100319475328460015245 No Anaesthesia and Reamination Department, Hasan Kalyoncu University, Gaziantep, Turkey Mustafa Yılmaz mstfyilmaz61@gmail.com 100319475328460015246 100319475328460015246 No Department of Physical Education and Sports, Gaziantep University, Gaziantep, Turkey Ahmet Koyunlu koyunluahmet@gmail.com 100319475328460015247 100319475328460015247 No Department of Physical Education and Sports, Gaziantep University, Gaziantep, Turkey
