Abstract

The purpose of this study was to examine the effects of combined cordyceps militaris, arginine and citrulline extract powder ingestion (Mitoceps Plus) on running performance under hot conditions among experienced long distance runners. A total of 6 male experienced long distance runners with age 42.5 ± 0.7 (Placebo), 37.0 ± 2.8 (Arginine-Citrulline) and 40 ± 0 (Mitoceps Plus); body mass index 20.2 ± 0.3 (Placebo), 22.3 ± 1.4 (Arginine-Citrulline) and 22.5 ± 1.8; years of running experienced 8.0 ± 1.4 (Placebo), 6.5 ± 2.1 (Arginine- Citrulline) and 11.5 ± 2.1 (Mitoceps Plus) with the VO2 max of 58.2 ± 3.2 (Placebo), 53.7 ± 0.5 (Arginine-Citrulline) and 57.6 ± 0.6 (Mitoceps Plus) were participates in this study. Participants underwent 1 preliminary test and 3 experimental trials. Preliminary test was to determine the maximal oxygen consumption of the participants. 3 Experimental trials were conducted to determine the muscle performance by doing countermovement jump test on the force platform, 45 minutes prolonged exercise test to determine the exercise economy and thermoregulatory response and incremental test was conducted to determine the time to exhaustion and maximal oxygen consumption. All the experimental trials were conducted under hot conditions with 35℃. All of the participants were required to consume the supplement for two 7 days and two 1 hour ingestion prior to the test. Results indicated that there were no significant differences in the time to exhaustion, circulatory response, thermoregulatory response, metabolic response, muscle performance, body composition changes and perceptual response between PET-0, PET-7 and PET-14. Hence, it was concluded that the Mitoceps Plus had little effect on PET-7 but no effect on PET-14 towards the physiological parameters that are vital to endurance running performance.
