Abstract: In this study we evaluated the effects of concurrent training protocols (strength – endurance against endurance – strength), on lipid profile and body composition in overweight females. Thirty overweight female students (age 23.2±2.4 yr, BMI 27.87±1.3 Kg/m2) were randomly divided into a three groups (n=10 in each group), concurrent strength-endurance (SE) group, concurrent endurance-strength (ES) group and control group (C). Concurrent training was conducted three times a week on alternate days for 8 weeks. The strength training consisted of 3 sets 8 repetitions with 80% of the 1RM for leg extensions, lying leg curl, triceps pushdown, bench press, lateral pull down and dumbbell lateral raise. Also the endurance training was performed a running for 10 min on the first day and increase the time of 30 seconds per sessions with 70-75% maximum heart rate (MHR) in the first 4 weeks and 75-80% MHR in the second 4 weeks. Blood samples were collected before and 48 hours after the exercise protocols. The result showed that both groups SE and ES significantly improved lipid profile (significantly reduces in TC, TG, LDL-C, VLDL-C and significantly increased HDL-C) and body composition (significantly decreased in body fat, body weight and increased body fat free mass but no significant) when compared to C group. Also no significant difference found between SE and ES groups in the lipid profile and body composition. It can be concluded that both SE and ES protocols nearly identical effects in positive transformation of lipid profile and body composition.
