Effects of cryotherapy and petrissage massage on functional signs of delayed onset of muscle soreness of knee extensors following stimulated plyometric exercise in Thai male

Abstract

This study focused on effects of cryotherapy and petrissage massage on functional signs of delayed onset of muscle soreness of knee extensors following stimulated plyometric exercise in Thai male aged 17-25 years old. Forty-five participants were equally randomized into 3 groups; cold-water immersion at 15°C (CWI), petrissage massage (MAS), and control (CON). Participants performed 100 drop jump exercise. Treatments were given within 10-15 min after the exercise for 20 min. Serum creatine kinase, soreness sensation, thigh circumference (TC), range of motion (ROM), strength test and vertical jump performance were measured 7 times; immediately before exercise, after exercise, after treatment, 24, 48, 72 and 96 h after exercise. All markers of DOMS were significant change compared to baseline (p<0.05) after the exercise indicating the presence of muscle damage, especially at 24-48 h. The results showed that there were significant different between groups on soreness sensation, greater on TC at mid-belly in CON compared with CWI group, greater on ROM in CWI and MAS compared with CON groups, greater on MVC (maximal voluntary contraction) in MAS compared with CWI and CON after the exercise (p<0.05). A lower in CWI compared with MAS and CON groups on vertical jump after 20 min treatment (p<0.05) were observed. These data reveal that petrissage massage could reduce soreness sensation and maintained ROM, and MVC following the exercise, compared to cryotherapy.
