Effect of short term workplace exercise intervention on lipid profile, depression, work ability and selected physical parameters of university employees in Saudi Arabia: A randomized controlled trail

Abstract

Objectives: The aim of the study was to examine the effect of 12 week exercise programme on lipid profile, depression, work ability and selected physical parametersin university employees. Methods/Analysis: Twenty-seven males with age ranging from (27-57 years) were randomized into intervention (n = 13) and control group (n =14). Twelve weeks of non-supervised exerciseprogramme was administered to intervention group. Exercise was performed twice a week consisting of 30 min of aerobic and resistance training.Mann Whitney Test was used to explore differences between two groups after 12 weeks of exercise programme. Findings: After 12 weeks significant improvement was seen in depression (P = 0.035), total cholesterol (P = 0.027), low density lipoprotein (P = 0.016), body weight (P=.0003), fat percent (P= 0.001), body mass index (P=0.01) and resting heart rate (P= 0.036) in exercise group while no significant improvement was observed in work ability (P = 0.138), high density lipoprotein (P = 0.097) triglycerides (P = 0.582), very low density lipoprotein (P = 0.523), fasting blood sugar (P= 0.233), systolic pressure (P= 0.223) and diastolic pressure (P= 0.908). Applications/ Improvement: Twelve weeks of non-supervised exercise programmewas effective and enhanced improvementin physical parameters and lowered total cholesterol and low density lipoprotein in maleemployees of university.
