Correlation Between Body Mass Index and Plank Holding Time in Rural Children

Background: Core stability is the ability to control the trunk posture and movements in reaction to internal and external perturbations. Slight alterations in body composition may affect Core stability. Purpose of the study: To find the correlation between lumbar Core muscle stability and BMI. Methodology: A study was conducted on 200 children with age between 6 – 12 years. Body Mass Index has been calculated for all the children. Plank test was conducted on them to measure the lumbar core muscle stability. Results: The result was analysed using Microsoft Excel 2016. The statistical tool used was Pearson correlation. The Pearson correlation for Body Mass Index and Plank time was -0.3975. The P-Value is < .00001. The result is significant at p < .05 level between Body Mass Index and plank time. Conclusion: The study concludes that there is a weak negative correlation between Body Mass Index and core stability. Key words: Core muscle, Plank, Body mass index, Children, Rural
