Correlation Between Core Endurance, Reaction Time, and Functional Capacity in School-Going Children

Abstract Background: Physical performance is influenced by the integrated ability of cardiovascular, pulmonary, and musculoskeletal systems, which form the functional capacity of an individual. Core endurance, functional capacity, and reaction time are crucial for daily activities. Children often face situations that require quick responses to uncomfortable situations, such as avoiding falls. Therefore, it is essential to assess the correlation between core endurance, reaction time, and functional capacity in school-going children to improve their daily living activities. Objective: The objective of this study is to determine the correlation between core endurance, reaction time, and functional capacity in school-going children between the ages of 5 and 16 years. Materials and Methods: Hundred children from schools in Belagavi between the ages of 5 and 16 years participated in this observational study. The children were recruited using convenient sampling and assessed for core endurance, reaction time, and functional capacity. The results were analyzed for correlation using Spearman’s Correlation Rank test. Results: For all participants, the functional capacity has shown a weak negative correlation with reaction time ( r = 0.27; P = 0.007). The core endurance showed a very mild positive correlation with functional capacity ( r = 0.13; P = 0.39) and a very mild negative correlation with reaction time ( r = 0.19; P = 0.20). Conclusion: The findings indicate a very weak and modest correlation between core endurance, reaction time, and functional capacity. This finding contributes to the body of material already in existence and may be used to plan training for young athletes.
