After Workouts Post-exercise ice treatments are rituals among athletes who push individual muscle groups to the max.
Delayed onset muscles soreness (DOMS) is caused by muscle damage during exercise that’s compounded by inflammation during recovery. Post-exercise ice treatments, so the theory goes, reduce inflammation and speed recovery. British researchers found that ice had no effect on post-exercise muscle soreness or on markers of muscle inflammation. They created thigh muscle soreness using high-intensity eccentric exercise (i.e., negatives) and immersed the leg in cold (33.8°F) or tepid (75.2°F) water for three 1-minute sessions. The ice therapy had no effect on muscle pain, swelling, leg power (one-legged hop for distance), maximal isometric strength or creatine kinase (a blood test used to estimate muscle damage). The authors concluded that icing after intense exercise might not promote recovery. However, three 1-minute ice treatments might not have been enough time to reduce post-exercise inflammation.
