The Effect of KAATSU Acute Resistance Training on Growth Hormone, Insulin-Like Growth Factor-1 and Lactate in Healthy Young Men

KAATSU training is effective and beneficial to improve different physical factors and is associated with lower muscular injury and inflammation. So, the aim of this study was to compare the effect of KAATSU training and no blood flow restriction on changes of growth hormone, insulin-like growth factor-1 and lactate in healthy young men. This study was semi-experimental with a repeated measurements design. It also used a counterbalance design. 10 young men (20-25 years old and BMI 21.36 kg/m2) were selected by a public call. KAATSU first session of resistance training started 72 hours after 1 RM was determined and blood pressure of quadriceps was evaluated. One week after the first session of KAATSU training, similar subjects performed the resistance training without blood flow restriction. Then, blood samples were collected in three phases to measure the mentioned variables. Results showed that lactate and growth hormone levels significantly increased in both groups especially after the second blood sampling (P
