Immediate effect of induced muscular fatigue on static and dynamic balance and core strength in male volleyball players

Abstract

Introduction: Muscular fatigue causes impaired joint proprioception and postural control which can affect performance. Fatigue affects the capacity of the muscle to generate force which ultimately leads to injuries and diminish performance. The effect of fatigue on static and dynamic balance in volleyball players was inadequately known. Aim: To assess the effects of induced muscular fatigue on static and dynamic balance and core strength in volleyball players. Methodology: Twenty male volleyball players were included in the study according to inclusion criteria. Dynamic balance by functional reach test, static balance by single leg stance and strength of core were evaluated before and after inducing the fatigue. Fatigue was induced by asking the participant to perform the squats till RPE of 10. Results: On data analysis using paired t test, a marked decrease in the single leg stance time mean from 26.63 seconds before fatigue to 22.55 seconds after inducing fatigue (p<0.05) was observed. A reduction in the functional reach distance covered by subjects from 31.8cms before fatigue to 29.33cms after inducing fatigue (p<0.05) was observed. A decrease in the core muscle strength from 42.25 mm Hg before fatigue to 41.85 mmHg after fatigue (p<0.05) was observed.
