AimThe present study was undertaken to evaluate the effects of different anaerobic training regimes on state anxiety, trait anxiety, and sleep quality among collegiate athletes.MethodsThirty-six collegiate soccer players fulfilling the eligibility criteria were randomly divided into three groups: complex training (n=12; BMI22.951.76 kg/m(2)), contrast training (n=12; BMI22.052.03 kg/m(2)), and control (n=12; BMI22.27 +/- 1.44 kg/m(2)). Athletes from the complex or contrast group were trained for 6 weeks (3 days/week). The complex group performed four different exercises, each comprised of strength [80% of one repetition maximum (1RM)] and power components alternately. The contrast group performed the same strengthening exercises alternately at two different intensities (40% and 80% of 1RM). No supervised training was given to control group. All athletes were tested for their state anxiety, trait anxiety, and sleep quality before and after 6 weeks of training.Results3x2 mixed ANOVA revealed significant difference in time effect (p <= 0.001) and time x group interaction (p <= 0.001) for state anxiety while non-significant difference was found in the group effect. There was no significant difference found between the groups for sleep quality and trait anxiety.ConclusionsThe results of the present study demonstrated that anaerobic exercises have a positive impact to reduce state anxiety. Therefore, coaches should utilize these findings and implement anaerobic exercises to the training regime for reduction of anxiety among athletes.
