Abstract : Universiti Pendidikan Sultan Idris
The objective of the study was to investigate and compare the acute metabolic response (energy expenditure (kcal), maximum volume of oxygen consumption (VO2max), respiratory exchange ratio (RER)) on Crossfit-based workout protocol and Tabata-based protocol. The study used a quasi-experimental method. 20 healthy and gym goer’s men aged 19-24 years old were involved in this study. Participants were assigned to perform Crossfit-based workout (“WOD” 17.1) and Tabata-based protocol with the same “WOD” with 80% 1RM dumbbell snatch and burpees box jump-over with 24 inch depth box equated based on total activity time for 14 minutes each within 90%-95% of maximum heart rate. The orders were randomize counterbalanced among the participants to avoid order effects. Paired sample t-test was conducted to compare the energy expenditure (kcal), VO2max, RER) between both protocol workouts. There was significant differences between energy expenditure per minute for both workout-based protocols, the analysis revealed that the Crossfit-based protocol workout burn more caloric expenditure (per minute) (m = 13.96, s = 1.37) compare to Tabata-based workout protocol (m = 13.29, s = 1.45), t (19) = 3.78, p ≤0.05. There was also a significant difference between VO2max for Crossfit-based workout and VO2max for Tabata-based workout. The Crossfit-based protocol workout consumed more oxygen intake (ml.kg-1.min) (m = 45.33, s = 5.33) compare to Tabata-based workout protocol (m = 44.11, s = 5.28), t (19) = 6.75, p ≤ .05. RER result also was significant difference between both workout-based protocols that the Crossfit-based protocol RER is higher (m = 1.27, s = 0.05) compare to Tabata-based protocol (m = 1.25, s = 0.04), t (19) = 3.380, p ≤ 0.05. To conclude, the different workout protocols used did affect the acute metabolic responses. The implication of this study highlights that the Crossfit-based protocol is more beneficial in acute response of energy expenditure, VO2max, and RER.
