2.3.5. Constant Load Test
To clarify the effects of prebiotic and synbiotic supplementation on inflammatory factors after prolonged aerobic exercise, the subjects warmed up for 3 min at 50% VO2max intensity and then exercised to exhaustion at 75% VO2max intensity to complete the constant load test [The relative values of VO2max for the PG group and SG group were 53.80 ± 1.57 mL/kg/min and 53.87 ± 1.64 mL/kg/min, respectively. During the constant load test, the warm-up speeds of the PG group and SG group were 7.12 ± 0.28 km/h and 6.85 ± 0.31 km/h, respectively, and the test speeds were 11.17 ± 0.42 km/h and 10.78 ± 0.46 km/h, respectively (
