The Effects of Resistance Training For 12 Weeks on Serum Calcium, Phosphorous and Parathyroid Hormone Levels of Urban and Rural Children

Abstract

Resistance Training (RT) is considered as an integral component of a comprehensive physical activity program for children and healthy adults and has shown to be an important component for the development of bone strength by improving their muscular power, nerve conduction, and deposition of minerals and maintenance of body balance. Objective: To determine the effects of resistance training on the mineral content of bone in children aged 11-14 years boys. Methods: Volunteer young boys between the ages of 11 to 14 years, 30 each from rural and urban setting of district Peshawar were recruited. Calcium, phosphorus, parathyroid hormone (PTH) and anthropometric parameters were measured before and after three months of resistance training. Paired sample t-test was used for changes over time. Results: The study found that there was a significant effect of resistance exercise on participant’s serum calcium level (8.44± 0.582 vs. 10.24± 0.786, p value<0.001), phosphorous (3.82± 0.265 vs. 4.59± 0.271, p value<0.001) and PTH (20.37± 4.620 vs. 29.20± 6.099, p value<0.001) in experimental group. Conclusions: Resistance training has an effective role in the increase of calcium, phosphorus and PTH and anthropometric measurements
