Abstract

Purpose: This study aims to investigate the effect of 6 weeks of severe short-term periodic training on blood glucose and serum lipid profiles indices in active young women. Method: For this purpose, 16 active and healthy young women with a mean age of 29±4/08 years, weight of 63.37 ± 4.66 kg, and height of 158/75 ± 6/13 were selected and assigned to experimental and control groups. The experimental group spent 6 weeks and 3 sessions in each week on the implementation of the training protocol. The main training of HIIT group (Experimental) included 3 repetitions of 30 sec pedaling on the wheel of the carburetor against the constant resistance of 7.5% of its body weight at maximum effort. To comply with the principle of overload, the number of 30-sec racing or pedaling activities increased during each week of training, and if the participants could complete 3 repetitions at a specified speed and load in 2 consecutive sessions, 10 percent would be added to the amount of loads. Recovery time between each repetition was inactive during 2 minutes of rest. Blood samples were taken from prepubertal vein in two stages: pre-test and post-test (after 6 weeks of training). The amounts of hemoglobin including A1C, LDL, TG, HDL, TC and blood glucose indices were measured and recorded as dependent variables. ANCOVA test was used to compare post-test results with control of pre-test results as covariance. Correlated t-test also was used to determine intra-group changes at each stage. Results: The results of this study revealed the positive effects of severe short-term periodic training on blood glucose and serum lipid profiles indices in active young women. In this study, 6 weeks of severe short-term training reduced blood glucose and hemoglobin A1C levels (P≤ 0.05). Levels of lipid profile indices were also improved. Serum levels of LDL and TC were reduced by exercises and HDL levels were also increased (P≤ 0.05). There were also changes in serum TG levels, and exercises could reduce the levels of this index, but changes were not significant (P≤ 0.05). According to the results, the percentage of body fat in active young women was also decreased significantly after exercises (P≤0.05). However, BMI loads were not significant. Conclusion: The results of this study showed the positive effects of severe short-term periodic training on blood glucose and serum lipid profiles indices in active young women. Extreme periodic exercises reduce blood glucose and improve glycemic indexes. Also, severe periodic exercises increase lipolysis and improve lipid profile while improving subcutaneous fat levels.
