Optimal pulmonary function is essential to good performance in all sports and normal life, the search for all related variables to excellent sports performance is never ending. This study aimed to determine the correlation between body composition (BC) and the pulmonary functions (PF) in male amateur boxers.
Material and Method. Twenty one male boxers who were at the training camp preparatory to an international game willingly participated in this prospective study. Participants’ ages ranged between 21 and 27years, and their weights and heights ranged between 50.00 and 99.35kg and 1.62 and 1.88m respectively. Participants’ body compositions of percentage body fat (%BF) and fat mass per weight (FMWt) were measured and analyzed by OMRON Body fat monitor (BF 302; Omron Co. Ltd., Japan) and the pulmonary parameters of Forced Expiratory Volume in 1 second (FEV1) and the Forced Inspiratory Volume (FIV) were measured with the use of full range peak flow meter (Philips, Respironics, UK) and portable hand held spirometer (Voldyne, Sherwood medicals, USA) respectively. Pearson Product-Moment and Spearman-rank order Correlation Coefficient statistical techniques were used to test correlation between the male amateur boxers’ BC and their PFs parameters, PFs and fighting results, while multiple regression analysis was used to determine the best BC predicting variables of PFs, at a significance of 0.05.
Results. The results revealed that there was a significant positive correlation between FIV and weight, height, %BF, and FMWt; and also between FEV1 and height. However, the results demonstrated that there was a negative insignificant correlation between FEV1 and age, as well as WHR.
Conclusion. It was therefore concluded that BC parameters have significant relationship with the inspiratory capacity of male amateur boxers but not the expiratory capacity. However, both forced expiratory and inspiratory capacities of male amateur boxers are not enhanced by increasing body fat content (adiposity) as measured by BMI and WHR.
