Abstract

Optimal athletic performance is strongly related to nutritional practices, especially the consumption of protein-based nutritional supplements among young athletes participating in high-intensity training. Nutritional supplement is commonly consumed by sprinters to aid muscle development and performance. However, the potential effects of nutritional supplement on cardio-pulmonary norms have not been sufficiently investigated, particularly in young athletic populations. Hence, the current study aims to examine the effects of nutritional supplement on cardiovascular parameters, pulmonary function, and sprint performance in young male sprinters undergoing a structured speed training program. A case-control experimental study was conducted with ninety-five male sprinters enrolled in the first and second academic years at the Faculty of Sports Science, Helwan University, Egypt. Participants were divided into a whey protein group (n=45) and a placebo group (n=50). Both groups were followed for a six-month duration, and pre- and post-intervention assessments were conducted, involving resting pulse rate, blood pressure, electrocardiography (ECG), spirometry measurement of total lung capacity, and 100-meter sprint performance. The results revealed that nutritional supplement showed an increased prevalence of transient alterations in resting pulse rate and the appearance of ECG adaptations (mainly an increase in QRS wave amplitude) compared to the placebo group. Moreover, total lung capacity increased significantly in both groups, but there was no significant between-group difference, suggesting the presence of a training-related effect. Moreover, sprint performance had a significant increase throughout the study period in both groups, with a slightly greater increase in supplemented sprinters. Overall, it was concluded that whey protein supplementation in sprint training contributes marginally to performance enhancement and is linked with short- term cardiovascular improvements, while pulmonary improvements seem to be a result of training. These results endorse careful and monitored consumption of nutritional supplement by young sprinters.
