Abstract
Background: It has been shown that prolonged exhaustive exercise, such as half-marathon running, could lead to transient post-exercise elevation of cardiac troponins, increase in oxidative stress, and mild decline in renal function in adolescent athletes. With increases in sports participation involving young people, there has been much interest in pre and post health evaluations following exercise. Evaluations can be used to identify pre-existing health confounders and to examine any detrimental responses that may occur post exercise. Study purpose & Methods: The purpose of this study was to evaluate pre and post exercise measures of cardiac function, serum albumin, systemic immunoglobulin (Serum IgA and IgG), cortisol and testosterone in adolescent (age: 16.2 ± 0.6) male endurance runners performing in 21-km maximal run. Results: Results revealed that cortisol, IgA and IgG levels significantly decreased 2, 4, and 24 h post exercise compared to pre-exercise levels (p < 0.05). Testosterone levels reduced 4 h post exercise (p < 0.05) but were restored to baseline values following 24 h. There were no changes recorded for albumin levels post exercise (p > 0.05). ECG assessments did not show any abnormalities at the T wave axis, ST segments and Q wave pre or post exercise. Conclusions: The findings from this study suggest that a single bout of prolonged maximum running is not likely to induce abnormal electrical activity in the heart, but does decrease serum immunoglobulin, and homeostasis of anabolic and catabolic hormones in trained adolescent endurance runners.
Highlights
There has been an increase young peoples’ participation in sport training [1]
This is in contrast to other studies, which have determined that prolonged submaximal exercise can result in elevated circulating testosterone levels [16], or no major differences in direct comparisons of exercise testosterone responses between endurance-trained and untrained male controls [17]
We found that at the time points of 2-h, 4-h, and 24-h post exercise, cortisol levels were significantly lower than pre-exercise values
Summary
There has been an increase young peoples’ participation in sport training (e.g., long-distance running) [1]. There is significant evidence supporting the inclusion of regular physical activity as beneficial for the prevention of chronic diseases and improvements in the general health of young people [3]. Participation by young athletes in intensive training and competition gives rise to several concerns. Pre-participation cardiovascular evaluation of young competitive athletes has been recommended in order to identify cardiovascular conditions that may cause sudden death or cardiovascular injury [4]. Researchers have revealed concerns about strenuous training regimes impeding growth and development [2]. There is evidence suggesting that intense training in young people often causes psychological damage [5]
