Effects of intermittent training programme on serum lipids and lipoproteins of young female adult University students in Nigeria
Excess adiposity has been associated with the incidence of chronic diseases like type 2 diabetes, cardiovascular diseases and some types of cancer. Exercise training has been used as an intervention to maintain normal adiposity in the body and thus control the incidence of chronic diseases. The purpose of this study was to find out the effects of intermittent training on TG, [Triglycerides] TC, [Total Cholesterol] LDL-C [Low Density Lipoprotein- Cholesterol] and HDL-C [High Density Lipoprotein Cholesterol] of healthy young female adult University students in Nigeria. A total of 32 volunteer female subjects were randomly assigned to two groups. Group (1) was intermittent training group with 16 female subjects, Group (2) was control group with 16 female subjects. All the subjects were tested for serum TG, TC, LDL-C and HDL-C before starting the training. These tests were repeated on all the subjects after 12 weeks of training. The subjects for intermittent training group underwent their respective training protocols for 30 minutes in each training session, 3 training sessions on alternate days per week for 12 weeks. The data thus collected were analysed using one way Analysis of variance (ANOVA) for the mean effects of the training protocols and interaction of training on serum TG, TC, LDL-C and HDL-C. The result showed significant decrease in serum TG, TC, and LDL-C due to 12 weeks intermittent training TG (8.27%), TC (8.20%), and LDL-C (14.8%) for female subjects. There was also significant increase in HDL-C as a result of the training programmes in female subjects, (13.5%). It was concluded that, intermittent training conducted for 30 minutes or above per session for 3 sessions on alternate days of a week at moderate intensity cause significant decrease in serum TG, TC, LDL-C and significant increase in HDL-C in young female adults. On the basis of the findings, it was recommended that intermittent training programme at moderate intensity (30 - 60% vo2max) should be followed at least for 12 weeks to produce desired favourable modification in lipids and lipoproteins of young female adults in Nigeria.
