Abstract: (10168 Views)
Background and purpose: The purpose of this study was to investigate the effects of single and repeated bouts of gymnastic training on salivary IgA and cortisol, in elite boy’s gymnasts.
Materials and methods: Twenty boys with mean age of 10 ± 0.8 years, height 145 ± 9 cm , weight 37 ±8 kg and body fat percent 14.2 ± 6(meam ± SE) in Ghaemshahr Club in 2007, performed the select and controlled gymnastic training in two bouts(single session, and double session), one week apart. The first bout, included one session a day, beginning at 6 to 8 P.M. and the second bout was performed in two sessions per day, beginning at 8.30 to 10.30 A.M and 6 to 8 P.M. Salivary samples ( 5 ml) to form un-stimulated were collected in pre-exercise, immediately after and 2 hours following gymnastic training. Levels of IgA and cortisol were measured by ELISA method. ANOVA test was performed for analysis of the obtained data.
Results: The IgA level indicated no significant change after two bouts of exercise within the same day (P>0.5), however, cortisol concentration increased (P<0.05). No significant correlation was observed between IgA and cortisol concentrations
Conclusion: These findings suggest that two bouts of gymnastic training (120-minutes), at moderate intensity with a 7.30 hours rest in between, had no effect on IgA concentration, but caused an increased in cortisol concentration.
