“…Recent studies suggest that exercise-induced changes in these anabolic hormones can be used by adolescent athletes and their coaches to optimize training (6,11). Interestingly, previous studies have shown that exercise may lead to simultaneous increase of antagonistic mediators, and stimulate both anabolic components of the GH→IGF-I axis (8,11), and catabolic proinflammatory cytokines (12,15,16). It was suggested that the very fine balance between the exercise-associated anabolic and catabolic response will dictate the effectiveness of training.…”

The present study compares previous reports on the effect of "real-life" typical field individual (ie, cross-country running and wrestling-representing combat versus noncombat sports) and team sports (ie, volleyball and water polo-representing water and land team sports) training on GH and IGF-1, the main growth factors of the GH→IGF axis, in male and female late pubertal athletes. Cross-country running practice and volleyball practice in both males and females were associated with significant increases of circulating GH levels, while none of the practices led to a significant increase in IGF-I levels. The magnitude (percent change) of the GH response to the different practices was determined mainly by preexercise GH levels. There was no difference in the training-associated GH response between individual and team sports practices. The GH response to the different typical practices was not influenced by the practice-associated lactate change. Further studies are needed to better understand the effect of real-life typical training in prepubertal and adolescent athletes and their role in exercise adaptations.

“…We reviewed and reanalyzed our previous studies [5,8,9,11] on the responses of hormonal and inflammatory markers to typical field practices in individual and team sports among late pubertal male and female athletes focusing on the inflammatory response. Characteristics of the participants and a brief description of the typical different practices are described below:…”

The present study compares previous reports on the effect of "real-life" typical field individual (i.e. cross country running and wrestling -representing combat versus non-combat sports) and team sports (i.e. volleyball and water-polo -representing water and land team sports) training on pro (IL-6) and anti (IL-1 receptor antagonist -IL-1ra) inflammatory mediators in male and female late pubertal athletes. An increase in IL-6 was found following each of the training sessions. In contrast, a significant increase in IL-1ra was found only following the cross-country, wrestling and water-polo practices and not following the volleyball practices in both genders. There was no difference in the inflammatory response between individual and team sports practices. The inflammatory response to the typical practices was correlated with the practice-associated lactate change. The greatest increase in IL-6 and IL-1ra occurred following contact sport practices, and was greater following land (wrestling) compared to the water (water-polo) practice suggesting that this increase may reflect muscle tissue damage and not necessarily training intensity. Further research is needed to better understand the influence of "real-life" typical training on exercise training adaptations of adolescent athletes.
