Abstract

This study aimed to determine whether aerobic cardioacceleration could significantly decrease DOMS and lactate accumulation from resistance training in resistance trained adults. 10 resistance trained male (age: 21.1 ± 2.3 years, weight: 72.9 ± 13.5 kg and height: 172.3 ± 9.7 cm) were randomly divided into equal Experimental (Exp) and Control (CON) groups. Both groups underwent the same resistance training three times a week with at least 48 hours of rest between sessions. Exp group performed one minute of inter-set aerobic cardioacceleration while CON group rested passively in a seated position. Heart rate was recorded using heart rate monitors (Exp: 60-84% HRR; CON: 20-39% HRR), DOMS level was self-reported 24 and 48 hours after each workout using Borg’s Rating of Perceived Pain (RPP) scale and blood lactate was measured using Accutrend Plus lactate analyzer before and after training on the first, third and fifth week. Results showed significantly less DOMS in Exp group compared to CON group at both 24 (P < 0.0001) and 48 (P < 0.0001) hours. Lactate accumulation was significantly lower in Exp group for week 1 (P = 0.0157), week 3 (P < 0.0169) and week 5 (P < 0.0001) as opposed to CON group. Therefore, performing inter-set aerobic cardioacceleration is effective in significantly reducing DOMS and lactate accumulation without negatively impacting performance in resistance trained adults.
