| Summary: | <p>The objective of the study was to investigate and compare the acute metabolic</p><p>response (energy expenditure (kcal), maximum volume of oxygen consumption</p><p>(VO2max), respiratory exchange ratio (RER)) on Crossfit-based workout protocol and</p><p>Tabata-based protocol. The study used a quasi-experimental method. 20 healthy and</p><p>gym goers men aged 19-24 years old were involved in this study. Participants were</p><p>assigned to perform Crossfit-based workout (WOD 17.1) and Tabata-based protocol</p><p>with the same WOD with 80% 1RM dumbbell snatch and burpees box jump-over</p><p>with 24 inch depth box equated based on total activity time for 14 minutes each</p><p>within 90%-95% of maximum heart rate. The orders were randomize counterbalanced</p><p>among the participants to avoid order effects. Paired sample t-test was conducted to</p><p>compare the energy expenditure (kcal), VO2max, RER) between both protocol</p><p>workouts. There was significant differences between energy expenditure per minute</p><p>for both workout-based protocols, the analysis revealed that the Crossfit-based</p><p>protocol workout burn more caloric expenditure (per minute) (m = 13.96, s = 1.37)</p><p>compare to Tabata-based workout protocol (m = 13.29, s = 1.45), t (19) = 3.78, p</p><p>0.05. There was also a significant difference between VO2max for Crossfit-based</p><p>workout and VO2max for Tabata-based workout. The Crossfit-based protocol workout</p><p>consumed more oxygen intake (ml.kg-1.min) (m = 45.33, s = 5.33) compare to</p><p>Tabata-based workout protocol (m = 44.11, s = 5.28), t (19) = 6.75, p .05. RER</p><p>result also was significant difference between both workout-based protocols that the</p><p>Crossfit-based protocol RER is higher (m = 1.27, s = 0.05) compare to Tabata-based</p><p>protocol (m = 1.25, s = 0.04), t (19) = 3.380, p 0.05. To conclude, the different</p><p>workout protocols used did affect the acute metabolic responses. The implication of</p><p>this study highlights that the Crossfit-based protocol is more beneficial in acute</p><p>response of energy expenditure, VO2max, and RER.</p> |
