Aims: The study aims to test the effectiveness High-Intensity Interval Training (HIIT) on metabolic parameters, such as maximal oxygen consumption (VO2 max), Hemoglobin level (HB), and heart rate variability (HRV).
Method: In an experimental approach, the participants (N=30) were divided into two (i)an experimental group doing HIIT training and(ii) a control group involved in their ordinary training session. Experimental groups underwent 8 weeks of high-intensity cycle ergometer interval training. Pre and two post-test between four weeks of the test included the above parameters.
Results: The finding shows that there is a significant difference in the effect of high-intensity interval training on the (VO2 max) and Heart Rate Variability (HRV) on the pre-test and post-test of Kedah Under 17 Footballers but no significant difference in the effect of high-intensity interval training on the Hemoglobin level (HB). Apart from that, there is also analysis showing that the control group (S) had only improved at a minimum level over the training period while the (H) group had shown good improvement while the (HE) group had portrayed excellent improvement throughout training and testing.
Impact: The study is to help the country improve the performance of athletes, this study is expected to inspire and spark ideas in the country's sports activists, especially coaches and national athletes.
Conclusions: The eight-week HIIT program improved cardiorespiratory fitness and hematological variables in all participants. Future research would be useful to further investigate the physiological changes resulting from HIIT programs.
