ABSTRACT

Introduction: Calf muscle fatigue is a common issue in physically demanding professions like construction work, where repetitive activities can lead to muscle exhaustion. This fatigue is thought to negatively affect balance and lower limb performance, increasing the risk of accidents and injuries. As these muscles become fatigued, their ability to maintain balance and generate power for tasks such as jumping or lifting can be significantly compromised. However, there is limited research focusing specifically on construction workers, a population that faces unique physical demands. Material and Methodology: A total of 150 construction workers (ages 25–45). Fatigue was induced through repeated heel raises until voluntary exhaustion. Participants performed the single- leg stance test for balance assessment and the vertical jump test to measure jump height before andafter fatigue following treatment was given. Pre and post fatigue results were statistically analyzed to determine significant changes. Result: Data were analyzed using Microsoft excel for statistical analysis. A paired t-test was conducted to compare pre- and post-fatigue results. Statistically significant decline in both balance (mean score reduced from 82.5 to 67.8) and jump height (39.2 cm to 35.1 cm), with p < 0.001. Following recovery intervention, both balance (77.2 sec) and jump height (37.6 cm) showed significant improvement (p < 0.001). Conclusion: Immediate calf muscle fatigue negatively affects postural stability and jump performance, which improves with short recovery strategies.
