ABSTRACT
Objective: During the COVID-19 pandemie period, weight control became an important health issue because of physical inactivity. Developing a valid and convenient tool to estimate energy consumption is a pressing task. Methods: This research investigates the invention patent method of rhythm speech test, introduces the smartphone sport supported fat & glucose calculator (SSFGC) program, applies it to estimation of fat and sugar consumption in endurance exercise of bicycle, and compares it with the results measured by gas analysis indirect calorimetry. The research recruited 12 males (age: 31.8±3.2 yrs, height: 171.6 ± 7.9 cm, weight: 71.2 ± 5.0 kg, peak oxygen uptake: 46.2 ± 5. 6 mL/min/kg, maximum power: 240 ± 50 watts, 15 watts/min progressive exercise load exhaustion time: 982 ± 197 sec and RER: 1.1 ± 0.1). Before the research, the research objects must be measured for peak oxygen uptake and basic physiological data. Participants must follow the SSFGC method of use during the 1 hour' s endurance exercise (30% V• O2peak -80% V• O2peak). The data derived from each analysis are expressed as mean ± standard deviation. The significance is set to p ≦.05. Results: According to SSFGC and gas analysis indirect calorimetry, estimated consumption of sugar (r =. 994, p <. 05) and fat (30% V• O2peak to 50% V• O2peak: r=.888, p <. 05;60% V• O2peak to 80% V• O2peak r=.817, p <. 05) exhibited high positive correlation between the two. Conclusion: The invention patent method of rhythm speech test, by importing SSFGC calorimeter program, can estimate the energy consumption of fat and sugar in stable endurance exercise, and provide the theoretical basis/or further application in the future. © 2021 A.
