• The purpose of this study was to compare the effects of rowing training combined with different breathing entrainment patterns on physiological changes during submaximal and maximal rowing exercise. Thirty-one male and female rowers were randomly assigned to a group (n=10) that did not intentionally control their breathing during rowing training, a group (n=11) that controlled their breathing at 2 breaths per stroke during training (2:1) and a group (n=10) that performed 1 breath per stroke (1:1) during training. The program included 8 weeks of stationary rowing (4d・wk^<-1>) and strength training (2d・wk^<-1>) that was equated between groups. Variables were measured during 3 different trials of submaximal rowing exercise that was performed using the 3 different breathing patterns (uncontrolled, 2:1 and 1:1) and during a maximal 2000-m simulated rowing race, before and after training. HR and VCO_2 were lower (p<0.05) during submaximal exercise after training regardless of which breathing frequency was used. Submaximal VO_2 at a breathing rate of 2:1 and 1:1 strokes per breath (p<0.05) and submaximal V_E at a frequency of 2:1 were decreased after training in all groups (p<0.05). Tidal volume was higher during the first half of the maximal 2000-m simulated rowing race after training only in the training group that controlled breathing at a rate of 1:1 (p<0.05). These results indicate that controlling breathing at 1 or 2 breaths per rowing stroke during submaximal exercise improves rowing economy after training. Ventilation was also lower after training when a frequency of 2 breaths per stroke was used during submaximal exercise. Training with a breathing frequency of 1 breath per stroke resulted in a higher tidal volume during the first half of the maximal 2000-m simulated rowing race. Therefore, the use of breathing entrainment during exercise in combination with training can improve some physiological responses to submaximal and maximal rowing exercise.
