Abstract

This study aimed to analyze the technical proficiency of the Gyaku Tsuki punch during kumite among karate athletes at Jambi Karate Club (JKC) using Dartfish video analysis. A quantitative descriptive observational design was applied. The population comprised all competitive athletes observed in the study setting, and total sampling was used, resulting in six athletes (n=6). Data were collected through video-recorded kumite bouts and an observation checklist that decomposed Gyaku Tsuki into 20 key performance indicators: guard readiness, stance execution and transition, body alignment and stability, hip rotation, punching trajectory, elbow extension, target direction (chudan), gaze control, and recovery to guard. Each item was scored dichotomously (correct=1; incorrect=0) and summed into a 0–20 total score, then classified using predefined norm intervals. Data were analyzed using descriptive statistics and percentage distributions. Results showed that 2 athletes (33.33%) achieved a “very good” category (17–20) and 4 athletes (66.67%) achieved a “good” category (13–16), with no athletes in moderate, poor, or very poor categories. In conclusion, overall Gyaku Tsuki execution during kumite was good, yet targeted technical refinement and pressure-specific practice are recommended to improve consistency and scoring effectiveness. Keywords: karate; kumite; gyaku tsuki; technique analysis; Dartfish

Abstract

This study aims to analyze the relationship between physical fitness levels and the occurrence of shortness of breath and hypothermia risk among novice climbers on mount sibayak, karo regency, north sumatra. The research employed a quantitative approach with a descriptive correlational design and a cross-sectional method. The sample consisted of 60 university students aged 20–24 years who participated in community service (kkn) activities and conducted mountain climbing. Physical fitness was measured using the harvard step test, shortness of breath was assessed using the borg dyspnea scale, and hypothermia risk was evaluated through body temperature measurements and clinical symptom observations. The results showed a strong negative correlation between physical fitness level and shortness of breath (r = -0.682; p = 0.001), and a moderate negative correlation between physical fitness and hypothermia risk (r = -0.543; p = 0.004). In addition, a moderate positive correlation was found between shortness of breath and hypothermia risk (r = 0.516; p = 0.007). These findings indicate that higher levels of physical fitness are associated with lower risks of respiratory disturbance and body temperature decline during mountain climbing. This study recommends the implementation of pre-climb physical fitness training and physiology-based safety education programs to enhance preparedness and safety among novice climbers in extreme environments.

Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan pemahaman dan keterampilan teknik dasar permainan bola basket pada mahasiswa Universitas Pembangunan Nasional Yogyakarta. Metode yang digunakan meliputi ceramah pengantar, demonstrasi teknik, latihan terbimbing, dan praktik langsung. Kegiatan dilaksanakan selama lima hari pada tanggal 9–13 Februari 2025 dengan melibatkan 150 mahasiswa dari berbagai program studi. Evaluasi dilakukan melalui observasi keterampilan sebelum dan sesudah kegiatan menggunakan rubrik penilaian pada aspek passing, dribbling, dan shooting. Hasil kegiatan menunjukkan adanya peningkatan rerata skor keterampilan pada seluruh aspek yang dinilai dengan kategori peningkatan sedang. Selain peningkatan keterampilan teknis, kegiatan ini berdampak pada meningkatnya kepercayaan diri dan partisipasi aktif mahasiswa dalam aktivitas olahraga. Program pengabdian ini berkontribusi pada penguatan kompetensi dasar bola basket serta mendorong pembiasaan aktivitas fisik di lingkungan kampus sebagai bagian dari upaya pembentukan gaya hidup aktif dan sehat.
