Kata kunci : Icefitt, Denyut Nadi, IL-6, Indeks Kelelahan, Speed endurance

Latihan fisik intensitas tinggi yang dilakukan secara berkelanjutan dapat meningkatkan biomarker inflamasi, berkontribusi pada kelelahan atlet. Interleukin-6 (IL-6) merupakan biomarker utama untuk inflamasi yang berkorelasi dengan peningkatan kelelahan otot. Penelitian ini bertujuan mengembangkan strategi manajemen kelelahan melalui pengelolaan inflamasi dengan metode baru bernama Ice Compression For Fitness (ICEFIT).

Indikator kelelahan yang diukur mencakup kadar IL-6, denyut nadi, dan hasil Repeated Anaerobic Sprint Test (RAST). Metode ini diharapkan menurunkan suhu tubuh dan meminimalkan kelelahan dengan menurunkan aktivitas inflamasi pada atlet. Penelitian ini menggunakan desain Randomized Control Group Pretest-Posttest dengan 32 atlet sepak bola yang memenuhi kriteria inklusi, dibagi menjadi dua kelompok: 16 atlet kelompok kontrol yang menjalani speed endurance training (SET) dan 16 atlet kelompok perlakuan yang menerima latihan SET dan intervensi ICEFIT. Intervensi ICEFIT dilakukan dengan kompres es pada leher, punggung, dan pinggang setelah latihan. Uji normalitas menunjukkan semua data berdistribusi normal (p > 0,05). Terdapat perbedaan signifikan dalam denyut nadi, kadar IL-6, dan hasil tes RAST sebelum dan sesudah latihan setiap kelompok (p < 0,05). Selain itu, terdapat perbedaan signifikan dalam perubahan denyut nadi, IL-6, dan RAST antara kelompok kontrol dan kelompok perlakuan (p < 0,05), yang menunjukkan bahwa pemberian ICEFIT memberikan dampak yang lebih baik dalam mengelola kelelahan dan inflamasi.

Pemberian intervensi ICEFIT pada atlet sepak bola yang menjalani latihan fisik intensitas tinggi (SET) secara signifikan mampu mengelola biomarker pro-inflamasi (IL-6), indikator kelelahan (RAST), dan denyut nadi. Metode ini terbukti efektif dalam mempercepat pemulihan atlet setelah latihan. Diperlukan penelitian lebih lanjut untuk mengevaluasi efektivitas ICEFIT dalam berbagai kondisi olahraga serta menguji pengaruhnya terhadap indikator pemulihan lainnya seperti laktat darah dan kadar kortisol. Implementasi ICEFIT diharapkan dapat menjadi bagian dari protokol pemulihan atlet di berbagai cabang olahraga.

Key words: Icefit, Heart Rate, IL-6, Fatigue Index, Speed Endurance

High-intensity physical exercise performed continuously can increase inflammatory biomarkers, contributing to athlete fatigue. Interleukin-6 (IL-6) is the primary biomarker for inflammation, correlating with increased muscle fatigue. This study aims to develop a fatigue management strategy through inflammation management using a new method called Ice Compression For Fitness (ICEFIT).

The fatigue indicators measured include IL-6 levels, heart rate, and the results of the Repeated Anaerobic Sprint Test (RAST). This method is expected to lower body temperature and minimize fatigue by reducing inflammatory activity in athletes. The study employs a Randomized Control Group Pretest-Posttest design with 32 soccer athletes meeting the inclusion criteria, divided into two groups: 16 athletes in the control group undergoing speed endurance training (SET) and 16 athletes in the treatment group receiving SET and ICEFIT intervention.

The ICEFIT intervention involves ice compression applied to the neck, back, and waist after training. Normality tests showed that all data were normally distributed (p > 0.05). Significant differences were observed in heart rate, IL-6 levels, and RAST results before and after training within each group (p < 0.05). Additionally, significant differences were found in the changes in heart rate, IL-6 levels, and RAST between the control and treatment groups (p < 0.05), indicating that ICEFIT intervention provided better outcomes in managing fatigue and inflammation.

The ICEFIT intervention for soccer athletes undergoing high-intensity physical training (SET) effectively managed pro-inflammatory biomarkers (IL-6), fatigue indicators (RAST), and heart rate. This method has proven to be effective in accelerating athlete recovery after training. Further research is needed to evaluate the effectiveness of ICEFIT in various sports conditions and to examine its impact on other recovery indicators such as blood lactate and cortisol levels. The implementation of ICEFIT is expected to become part of athlete recovery protocols across various sports disciplines.
