Abstract

Lower-extremity musculoskeletal injuries are common in sports characterized by explosive movements and repetitive kicking activities, including pencak silat. The straight kick is one of the commonly used attacking techniques and requires speed, intersegmental coordination, and the ability to maintain the stability of the supporting leg. This study aimed to analyze the biomechanical characteristics of the straight-kick technique and determine the relationship between biomechanical parameters and indicators of lower-extremity neuromuscular control associated with the risk of musculoskeletal injury among pencak silat athletes at FIKK UNM. This study employed a quantitative observational cross-sectional design involving 20 active pencak silat athletes aged 18–25 years selected through purposive sampling. Kicking movements were recorded in the sagittal and frontal planes and analyzed using Kinovea software to obtain hip, knee, and ankle joint angles, lower-limb segment velocity, and the Frontal Plane Projection Angle (FPPA) of the supporting leg. Neuromuscular control was assessed using the Single Leg Squat Test (SLST). Data were analyzed using descriptive analysis, the Shapiro–Wilk normality test, and Pearson or Spearman correlation tests. The results showed a very strong positive relationship between SLST FPPA and supporting-leg FPPA during the straight kick (r=0.885; p<0.001), whereas the kicking-leg parameters showed no significant relationships (p>0.05). These findings indicate that frontal-plane control of the supporting leg assessed through the SLST is associated with lower-extremity alignment during the straight kick and may support physiotherapy-based injury prevention strategies for pencak silat athletes.
