Conditions

To investigate the effects of sago (daily used local food containing mostly CHO), soy (daily used local food containing PRO), and iso–caloric sago+soy combined (CHO and PRO combined supplementation) supplementation during a 90–min endurance cycling at 60 % of VO2max on cycling performance in the heat. Activity, other specified sports and athletics

Interventions

Intervention 1: Intervention group: Sago-These ingredients were sago flour (75 gr in 1 liter) that obtained from Sim Company Sdn. Bhd. Penang (Ghosh et al., 2010), and it was mixed with 5 mL of non–ca

Design outcomes

Primary

Measure	Time frame
The 20–km time trial performance in the heat,. Timepoint: At 20 min intervals during cycling at 60% VO2max, participants consumed either SA, SO, SS, or a PL. Method of measurement: This test was performed by using the electronically braked ergometer (Excalibur Sport, Lode, Groningen, The Netherlands). Participants were requested to perform the 20–km time trial on another bike (One Series Aluminium, Trek Road Bikes, USA). This bike was supported by a trainer (CycleOps Power JetFluid Pro Trainer, Wisconsin, USA). Meanwhile, they were free to control the speed of the cycling via a digital cyclometer (Cateye Strada Wireless, CC–RD300W, Japan). During the experimental trials, heart rate was measured by a heart rate monitor (S710, Polar Electro, Finland). A heart rate monitor sensor (Sport Tester, PE 3000, Polar Electro, Finland) was fitted on the chest wall of the participants’ body to transmit the data to the heart rate monitor.;Blood glucose. Timepoint: The blood sampling (8 mL) were collected after at -30 min, 0 min, 30 min, 60 min, 90 min, and after time trial performance. Method of measurement: Enzymatic oxidation method was applied to analyse the plasma glucose concentration within 60 minutes by spectrophotometer (Spekol 1200, Germany).;Free Fatty Acid. Timepoint: The blood sampling (8 mL) were collected after at -30 min, 0 min, 30 min, 60 min, 90 min, and after time trial performance. Method of measurement: Acyl–CoA synthetase–Acyl–CoA oxidase method (ACS–ACOD) was used to analyse the plasma Free Fatty Acid concentration by spectrophotometer (Spekol 1200, Germany) at 550 nm.;Insulin. Timepoint: The blood sampling (8 mL) were collected after at -30 min, 0 min, 30 min, 60 min, 90 min, and after time trial performance. Method of measurement: The Roche Cobas insulin method (ROCHE Elecsys 2010, Roche Diagnostics, USA) was applied in this research to measure the insulin concentration which employs a biotinylated monoclonal insulin–specific antibody and a monoclonal ins	—
