Abstract

The purpose of this study was to examine the acute physiological effect of caffeine on HIIT training among normal weight young adults. A total of 15 normal weight young adults (age: 21.33 ± 2.02 years; weight: 66.58 ± 10.18 kg; height: 168.03 ± 5.72 cm; SMM: 29.23 ± 4.97 kg; PBF: 21.19 ± 8.56 %; VO2max 32.81 ± 8.33 ml.kg.min-1 ) from Tunku Abdul Rahman University College were recruited in this study. They undertook 2 experimental trials which included 1 CAF trial (5kg/BW) and 1 PLA trial (decaffeinated coffee) 60 min prior to the HIIT training (20 min of interval training with cycling to rest ratio of 10/50 s at ≥90% HRpeak). Each test was separated at least 7 days apart. Results showed that Cardiorespiratory (Blood Pressure & Heart Rate) responses have no significance changes (p>0.05). But the VO2 responses there is a significance effect towards HIIT training between CAF and PLA trails (p < 0.05). Blood Glucose showed that there was a significant effect towards HIIT training between CAF and PLA trails (p < 0.05). Results showed that there was no significant difference in the Body Composition (Skeletal Muscle Mass, Percentage of Body Fat, Body Mass & Extracellular Water) responses towards HIIT training between CAF and PLA (p>0.05). Results also showed that there was no significant difference in the Rating of Perceived Exertion (RPE) responses towards HIIT training between CAF and PLA (p>0.05) In conclusion, the present study demonstrates the ingestion of caffeine (5mg/BW) 60 min prior to the testing improved VO2max and reduce the usage of blood glucose towards exercise
