Background: Previously, yoga bellows-type breathing (bhastrika pranayama) reduced reaction time (RT) or reduced anticipatory responses in male participants or a mixed group of male and female participants.Aims: The present study as a control trial aimed to assess the effects of yoga bellows-type breathing on RT in females exclusively.
Methods: The sample consisted of 25 healthy females, aged between 19 and 32 years (group mean ± standard deviation, 22.8 ± 3.5 years). All of them had prior minimum experience of yoga including yoga bellows-type breathing of 12 months. The RT was assessed in each participant before and after three randomized sessions differed in the intervention given held on three separate days. The sessions were (i) YOGA bellows-type breathing or bhastrika pranayama(BHK), (ii) Breath awareness (BAW), and (iii) Sitting quietly (CTL) as a control session. The duration of the intervention was 18 min, and the participants were assessed for RT before and after the intervention.
Results: Repeated measures ANOVA, post hoc tests with Bonferroni adjusted showed that the time taken to obtain a correct response reduced significantly after 18 min of BAW (P < 0.05) and CTL (P < 0.05). However, no changes were seen in the RT after BHK.
Conclusions: The results suggest that different interventions may optimize performance in tasks requiring attention in females compared to males.
Pre-teen children face stressors related to their transition from childhood to adolescence, with a simultaneous increase in academic pressure. The present study compared the immediate effects of 18 min of (i) high frequency yoga breathing with (ii) yoga-based breath awareness and (iii) sitting quietly, on (a) attention and (b) anxiety, in 61 pre-teen children (aged between 11 and 12 years; 25 girls). Attention was assessed using a six letter cancellation task and Spielberger’s State Trait Anxiety Inventory STAI-S was used to measure anxiety before and after the three practices, practiced on separate days. Repeated measures ANOVA, followed by Bonferroni adjusted post-hoc analyses showed an increase in total attempts and net scores after high frequency yoga breathing (p < 0.05), while wrong attempts increased after yoga based breath awareness (p < 0.05). Anxiety decreased comparably after all three interventions. The 25 girls in the group had the same trend of results as the whole group with respect to the attention-based cancellation task, while boys showed no, how since change. For both girls and boys, anxiety decreased after all three 18min interventions. The results suggest that high frequency yoga breathing could be a short, useful school based practice to improve attention and reduce anxiety.
