Kaatsu method associated with inspirational muscle training with minimum load versus traditional inspirational muscle training in healthy Non-trained individuals

The method of training with partial blood flow occlusion has been one of the great research targets of health professionals in recent years for having significant results in high performance athletes. At the same time, Inspiratory Muscle Training (IMT) provides an improvement in the functionality of inspiratory muscles, including the diaphragm, generating morphological changes. The objective of the present study was to evaluate the influence of the KAATSU (KT) method on Inspiratory Muscle Training. This is a randomized clinical trial consisting of 22 untrained, healthy patients divided into two groups (IMTG + KT: 13, IMTG: 9). Both groups performed spirometry before and after the protocol. The groups were submitted to a protocol of 8 sessions, in which the Inspiratory Muscle Training + KAATSU Group (IMTG + KT) was performed with an initial load of 40% of the Maximum Inspiratory Pressure (MIP) associated to the vascular occlusion training in the proximal third of the humerus, inflating to 220mmHg. The IMT Group (IMTG) training was carried out with 70% of Maximum Inspiratory Pressure (MIP). It was observed that both protocols obtained significant results in the spirometric variables of Forced Expiratory volume (FEV 1) and Forced Vital Capacity (FVC) pre and post intervention. However, IMTG + KT was significantly higher when compared to IMTG at all evaluated points.
