“…6,2010 and menarche. 33 After menarche the rate of this increase declines, and there is a gradual rise during the teens, with adult levels reached between 18 and 20 years of age 34,35 . Despite these fluctuating levels of hormones, their direct impact on the incidence of URTI remains unclear.…”

In this study we examined whether salivary hormones, physical activity and adiposity were correlated with secretory immunoglobulin A (sIgA) and frequency of upper respiratory tract infections (URTI) in 43 early-pubertal and 59 late-pubertal girls. Physical activity was measured using accelerometers and relative body fat was assessed using bioelectrical impendence. Resting saliva samples were obtained between 1500 and 1800hr and assayed for sIgA, cortisol and testosterone. Participants completed a onemonth health log to record URTI frequency. Early-pubertal girls were more physically active, had less adiposity, but lower concentrations of sIgA than late-pubertal adolescents (122.7±91.6 vs 201.9±102.9 pg/ml, respectively). The frequency of URTI was similar in the two groups. Neither sIgA nor URTI were correlated with salivary hormones, physical activity or adiposity within the earlypubertal girls. In the late-pubertal group, sIgA was negatively associated (r=-0.44; p≤0.05) with cortisol, and positively associated (r=0.41; p≤0.05) with the testosterone to cortisol ratio. These results suggest that mucosal immunity increases with pubertal maturation, while higher cortisol is associated with lower mucosal immunity in adolescents.

“…The sT concentrations in pre-pubertal male subjects remain stable from six to nine years of age [36], and in healthy males an increase is observed, starting from nine to ten years of age, depending on pubertal development. As expected, in our young athletes the mean sT concentrations were significantly correlated with both chronological age and pubertal stages, but regardless of the method of class selection, high intra-class variability and evident inter-class overlaps were observed (Figs.…”

Puberty influences both the performance and the hormonal responses to exercise-related stress. We evaluated the distribution and the correlation between pubertal characteristics and the salivary cortisol (sC) and testosterone (sT) responses to acute physical exercise in young male athletes (13.4 +/- 2.1 yr, n = 110). The mean pre-exercise nmol . L (-1) sC and sT concentrations were 19.08 +/- 4.32 and 0.34 +/- 0.15 and increased to 21.27 +/- 5.51 and 0.41 +/- 0.16 after a 90-min training session (p < 0.01). The sC concentration at rest was positively correlated with chronological age (p < 0.01) and negatively correlated with fat % (p < 0.05), whereas significant negative correlations of DeltasC and DeltasC% after exercise with age, pubertal stage and mean testis volume (p < 0.05) were observed. The sT increase after exercise was correlated with chronological age, pubertal stage and pre-exercise sT levels (p < 0.01), whereas the DeltasT and DeltasT% of increase were negatively correlated with chronological age and resting sT levels (p < 0.05 and p < 0.01). In the present study, we observed the presence of high inter-individual variability of different biological parameters (anthropometry, pubertal stage, hormones, etc.) within athletes selected by chronological age in the same class and the presence of significant correlations between chronological age, puberty and the steroid hormone responses to physical exercise. Our data suggest the need for different criteria in exercise prescription and selection of young athletes and in the evaluation of stress reactivity at puberty.

“…Somewhat similar to cortisol, testosterone has been shown to increase linearly in response to exercise, reaching its peak concentration once activity has ceased (Wilkerson et al 1980). Although it provides a non-invasive method of assessing the free, biologically active fraction of circulating testosterone (Ohzeki et al 1991), not many studies present salivary testosterone data on children and adolescents (Ostatníková et al 2002). However, Falgairette et al (1991) reported signiWcant associations between salivary testosterone (SalT), and peak and mean anaerobic power in boys aged 5-16 years.…”

The effect of anaerobic exercise on salivary cortisol, testosterone and immunoglobulin (A) in boys aged 15–16 years

This study investigated the effect of repeated bouts of short-term, high-intensity cycling exercise on the salivary cortisol, testosterone and immunoglobulin (A) concentrations of 15-16 year old boys. Seventeen apparently healthy schoolchildren (aged 15.5 +/- 0.4 years) participated in this study. All participants completed 6 x 8 s sprints, interspersed with 30 s recovery intervals on a cycle ergometer. Using the passive drool method, salivary samples were taken before, and 5 min after, exercise. The group mean for peak power output was 723.1 +/- 180.3 s. There were significant changes (p < or = 0.05) in both SalT and SalC, 5 min after completing 6 x 8 s cycle sprints. No significant differences (p > 0.05) were recorded for SIg(A). The increases in SalT and SalC reported in this study confirm that repeated bouts of short-term, high-intensity exercise produces significant physiological hormonal responses in adolescent boys, but does not affect mucosal immune function.
