Effect Of Ultrasound Versus Cryotherapy On Blood Lactate Levels In Delayed Onset Of Muscle Soreness

Abstract

Delayed Onset of Muscle Soreness (DOMS) is commonly associated with high-intensity or unfamiliar physical activity, leading to symptoms like muscle pain, stiffness, and discomfort. This study compared the effects of ultrasound and cryotherapy on blood lactate levels in individuals experiencing DOMS. Thirty sedentary participants aged 18-25 were randomly assigned to three groups: a control group (Group A) received no treatment, an ultrasound group (Group B) received 5 minutes of pulsed ultrasound at 0.8 w/cm², and a cryotherapy group (Group C) received 15 minutes of ice pack application. DOMS was induced through a 40-minute skipping exercise, with blood lactate levels measured pre-exercise, 8 hours pre-exercise and at 24-, 48-, and 72-hours post-treatment. The results showed that both ultrasound and cryotherapy significantly reduced blood lactate levels compared to the control group. Cryotherapy demonstrated more substantial impact on reducing blood lactate, particularly at 72 hours post-exercise when compared to Ultrasound therapy. These findings align with previous research suggesting cryotherapy’s effectiveness in enhancing muscle recovery and reducing inflammation. Ultrasound therapy also aided in lactate reduction, likely through improved blood flow and muscle oxygenation. In conclusion, cryotherapy may offer a superior advantage over ultrasound for managing DOMS, making it a preferable option for faster recovery. Further research with larger samples and varied populations is recommended to expand on these findings and refine recovery strategies in athletic and clinical settings
