This project will be Randomized control trial conducted to check the effects of percussive massage treatment with theragun on pain and muscle length on post exercise delayed onset muscle soreness (DOMS) of calf muscles in healthy population so that we can have best treatment option for people with delayed onset muscle soreness, duration will be of 6months,purposive sampling will be done, subject following eligibility criteria from kasrat health and fitness club, will randomly allocated in two groups, baseline assessment will be done, group A will be treated with 5 minutes of percussive massage and 5 minuties of static stretching exercises, while group B will be managed with 5 minutes of static stretching exercises only. Assessment will be done via, Numeric Pain Rating Scale(NPRS), Short-Form McGill Pain Questionnaire (SF-MPQ) and goniometric measurements of passive ankle dorsi flexion for calf muscle length at baseline before intervention and immediately post intervention data will be analyzed by using SPSS version 25

Percussive therapy is a form of soft tissue manipulation the same thing that a massage therapist does during a massage, and is intended to reduce muscle soreness and increase muscle length. The aim of the current study is to determine the effects of percussive massage with theragun and static stretching exercises on muscle length and pain of calf muscles on post exercise (DOMS) delayed onset muscle soreness. It will be a randomized control trail, where initial screening will be done as per the inclusion criteria of healthy female gym users with minimum one week of joining time and developed post-exercise DOMS and ages ranged from 20 to 30 years. Participants with the history of lower leg injuries, any type of neuromuscular disorder and elite level of fitness will be excluded. All the study participants will perform 15 minutes treadmill, 15 minutes stationary bicycle at day one. After 24 hours participants with positive DOMS will be randomly place into experimental and control groups. Experimental group will be treated with 5 minutes of percussive massage and 5 minutes of static stretching exercises, while the control group will be managed with 5 minutes of static stretching exercises only. Participants in both the groups will be assessed on Numeric Pain Rating Scale and Short-Form McGill Pain Questionnaire for pain and degree of passive ankle dorsi flexion for calf muscle length at baseline before intervention and immediate 24 hours, 48 hours and 72 hours after the completion of treatment session.

Inclusion Criteria:

Healthy Females will be included Participant's age will be between of 20-30 years Who develops post exercise DOMS after 15 minutes treadmill, 15 minutes stationary bicycle

Exclusion Criteria:

Subject with history of lower extremity injuries Any history type of muscular disorder Elite level of fitness excluded in this study
