Abstract

Background and Study Aim. During exercise, the work of the heart will be controlled by sympathetic nerves that will regulate the frequency of heart rate through the depolarization effect. Faster changes in depolarization effects can affect action potentials that become more frequent, so that the heart rate will increase. Stretching serves to improve blood flow and circulation, so it can help in lowering the pulse rate. This study aims to determine the effectiveness of PNF stretching on pulse rate recovery after doing HIIT on futsal players.Material and Methods. This research is an experimental research with the design of this research is control group pretest-posttest consisting of 20 people with sampling technique using population sampling. They were divided by ordinal pairing into two groups, namely the PNF stretching group and the control group. The PNF stretching group underwent PNF stretching session after HIIT session, while the control group only did HIIT session without PNF stretching. Recovery pulse rate was measured before and after the HIIT session, as well as after the PNF stretching intervention or rest period for the control group. Analysis was assisted using SPSS 26.Results. The results showed a significant decrease in recovery pulse rate in the experimental group with an average pretest value of 75.6, posttest 86.8 (p=0.000) with an effectiveness value of 85.8%. The control group showed a less significant decrease in recovery pulse rate, with an average pretest value of 75.2, posttest 76.8 (p=0.104) with an effectiveness value of 75.8%.Conclusion. So that this research is expected to serve as material for consideration, reference, and knowledge for parties related to the world of sports and health science, especially the effectiveness of Proprioceptive Neuromuscular Facilitation (PNF) stretching on pulse recovery after doing High Intensity Interval Training (HIIT).

Abstract

Background and Study Aim. The participation of female athletes in a sporting event in each country is very minimal compared to men, basically the State policy has not fully allowed female athletes to wear the hijab. Hijab is familiar to Muslim women but on the other hand the policies of their respective countries do not support Muslim women participating in a sporting event by wearing hijab. This study aims to explore the involvement of Muslim women who wear hijab in international sporting eventsMaterial and Methods. This research used Harzing Publish or Perish to start the search, Scopus database was used, which is considered as one of the best citation indexing tools. The criteria used the PRISMA protocol (preferred reporting items for systematic reviews and meta-analyses). The keywords of this research are (“Muslimah” AND “Sportswear” AND “Women's Participation” OR “Women in Sports”). Based on these results, only 7 journal articles were used in the systematic literature review in this study.Results. The result of this study is that the gradual increase in the number of female Olympians obscures the reality that a woman's opportunity to participate and compete in sports. It can be seen that in several countries there has been an increase in the number of Muslim female athletes participating in championships in the international arena, but the policies given have not allowed female athletes in all sports to cover the aurat or wear the hijab, the obligation of a Muslim is to cover the aurat, which in principle between policies and obligations become two things that intersect.Conclusion. In conclusion, despite a noticeable increase in the number of Muslim female athletes participating in international championships, policy limitations still prevent female athletes in some sports from covering their aurat or wearing the jilbab.

Abstract

Background and Study Aim. ACL reconstruction is the surgical replacement of the anterior cruciate ligament with a tissue graft to restore knee function. To avoid problems including edema, loss of range of motion, muscle weakness, poor balance, and recovery of knee function, rehabilitation treatment should be performed after surgery. Immediate implementation of open kinetic chain exercises, use of criterion-based progressions for various activities such as running, sprinting, and plyometrics, and implementation of a secondary prevention program. This clinical practice review is to discuss the parameters associated with the rate of phase repair for ACL repair and to guide therapists according to the parameters of postoperative healing.Material and Methods. The patient presented with a knee brace still in place, swelling and incision marks above the patella, and atrophy of the dextra quadrisep muscle, the patient still had difficulty bending and straightening his right knee, and used crutches to help him walk. The modalities given are massage, electrotherapy (TENS), various exercises (exercise therapy), stretching, and cryotherapy.Results. There are five phases of rehabilitation: maximal protection, moderate protection, minimum protection (initial strengthening), Neuromuscular Control and Functional Training (strengthening-cardiovascular conditioning), and maintenance and Return to Activity (controlled agility-advanced conditioning). These stages are to help reduce swelling, increase joint range of motion, increase muscle strength, and reduce pain.Conclusion. Periodization theory should be fundamentally understood by sports rehabilitation professionals, especially physical therapists and sports medicine physicians. So that a safe and organized postoperative procedure can be established.
