摘要:The purpose of this study was to investigate the efficacy of post-exercise treatment with “Cool Veil Serum (CVS)” developed by Madre:X Co. Ltd. (Shibuya, Tokyo) to prevent exercise-induced muscle swelling. Calf circumferences and mus-cle stiffness of both legs were measured in 10 healthy female. The measurements were made on before 5-minute exercise, after the exercise, and after 10-minute recovery care with CVS and 5-minute rest. The recovery care was applied only on right leg of the subjects. Then, multiple comparisons of calf circumference and muscle stiffness on each leg among pre-exer-cise, post-exercise, and final measurements were carried out. Exercise caused a significant increase in calf circumference and muscle stiff-ness. The recovery care with CVS rapidly re-duced postexercise calf circumference to pre-exercise level. Relationship between reduc-ing muscle swelling after exercise and prevent-ing sport injury should be explored in further studies.
