The purpose of this study was to investigate the effect of post-challenge acute values of serum cortisol levels in elite and sedentary athletes before aerobic exercise. This study included 22 elite middle-distance runners from various clubs around Turkey and 16 voluntary non-athlete men. The Cooper test was applied to study subjects. Heart rate values and blood samples of the subjects were taken before and after the Cooper test. The blood samples were analyzed at Central Biochemistry Laboratory of Şahinbey Research and Application Hospital of Gaziantep University. The results showed statistically significant difference between sedentary and athlete groups in comparison of BMI (P<0.05). A statistically significant difference was also found in pre-exercise cortisol and potassium levels and post-exercise lactate and potassium levels between both groups (P<0.05). No statistically significant difference was detected between groups in comparison of other blood parameters (P>0.05). Again, no statistically significant difference was found between pre-test and post-test values of pre and post-exercise Cortisol and Potassium levels of both groups (P>0.05).Consequently, cortisol levels were same in both groups and were not affected by exercise. According to these results, it can be said that athletes’ volume of air entering the lungs is higher than those who do not do sports, and the level of their anaerobic respiration is lower.

“…Porém, os valores de VO 2max abs, VO 2max rel expresso por kg da MC e VO 2max rel expresso pela massa magra, foram 31,5%, 21,2% e 20,6%, respectivamente, mais altos para os nadadores do que para os escolares (p<0,05). Os autores sugerem que o treinamento físico proporcionou esse aumento significante do VO 2max nos jovens sujeitos 25 .…”

Foram avaliados 71 sujeitos entre 7-17 anos de idade (35Nad e 36Esc), distribuídos em grupos etários de 7-10, 11-14 e 15-17 anos. Foram realizadas medidas antropométricas (Estatura, Massa Corporal e Somatória de Dobras Cutâneas) e metabólicas (VO 2pico), utilizando o sistema de análise de gases VO2000® e uma esteira rolante Inbrasport ATL®, adotando o protocolo de Bruce adaptado. Análise estatística: ANOVA para medidas repetidas, seguidas pelo teste post hoc de Tukey (p<0,05). VO 2pico absoluto: diferenças estatísticas significantes entre todos os grupos etários e entre Nad (0,99 + 0,20 e 1,27 + 0,21 L.min-1) e Esc (0,98 + 0,36 e 0,80 + 0,12 L.min-1). VO 2pico relativo: diferenças estatísticas significantes entre Nad1 e Nad2 (10,88 + 0,09 e 0,75 + 0,47 ml.kg-1 .min-1) e entre Esc1 e Esc3 (6,96 + 1,23 e 0,98 + 2,29 ml.kg-1 .min-1), apesar de serem diferentes entre Nad e Esc. Os resultados indicaram aumento do VO 2pico entre os grupos etários, fruto do desenvolvimento natural dos sujeitos, mas, sobretudo, do efeito do treinamento de natação. Apesar do comportamento dessa variável ser similar entre 11-14 e 15-17 anos para ambos os grupos, os valores entre Nad e Esc nesses períodos etários são diferentes, apresentando os maiores valores para os Nad.

“…(1992) with 15-year-old boys, where it was shown that the maximal aerobic power expressed per kilogramme lean body mass was 20.6% higher in the trained than in the untrained group (136). From the similar functional capacity of the fat free mass for subjects with a solid, average or slender body build in this study, suggests a similar physical exercise level in the groups.…”
