Does exercise training alter cardiorespiratory coordination in young males?
Exercise training alters cardiorespiratory coordination, as measured by principal component analysis, which may be a more sensitive marker than traditional cardiorespiratory reserve.
p-value: p=0.01
Our purpose was to study the effects of different training modalities and detraining on cardiorespiratory coordination (CRC). Thirty-two young males were randomly assigned to four training groups: aerobic (AT), resistance (RT), aerobic plus resistance (AT + RT), and control (C). They were assessed before training, after training (6 weeks) and after detraining (3 weeks) by means of a graded maximal test. A principal component (PC) analysis of selected cardiovascular and cardiorespiratory variables was performed to evaluate CRC. The first PC (PC1) coefficient of congruence in the three conditions (before training, after training and after detraining) was compared between groups. Two PCs were identified in 81% of participants before the training period. After this period the number of PCs and the projection of the selected variables onto them changed only in the groups subject to a training programme. The PC1 coefficient of congruence was significantly lower in the training groups compared with the C group H (3, N=32) = 11.28; p = 0.01. In conclusion, training produced changes in CRC, reflected by the change in the number of PCs and the congruence values of PC1. These changes may be more sensitive than the usually explored cardiorespiratory reserve, and they probably precede it.
Balagué et al. (Fri,) conducted a rct in Healthy, physically active males (n=32). Aerobic, resistance, or combined training vs. Control (usual activities) was evaluated on Principal component 1 (PC 1) coefficient of congruence (p=0.01). Six weeks of aerobic, resistance, or combined training significantly improved cardiorespiratory coordination, reflected by a lower principal component 1 coefficient of congruence compared to control (p=0.01).
