Abstract

The purpose of this study was to find the most efficient breathing mode at different exercise intensitiesand alsothe specific work intensity of which breathing mode is more efficient for oxygen consumption. A total of 20 recreational cyclists (age: 20.35 ± 1.27 years old; body weight: 64.27 ± 4.33 kg; height: 168.63 ± 3.06 cm; Maximal oxygen uptake(VO2max): 41.98 ± 5.39ml.kg-1.min-1) from Tunku Abdul Rahman University College were recruited in this study. They underwent 1 preliminary trial and 2 experimental trials (Oral Breathing Trial and Nasal Breathing Trial). Each experimental trial consisted of 3 stages with 12 minutes (4 minutes for 1 stage) cycling on the MONARK 894E PEAK BIKE. Each trial was separated for at least 2 days. Results indicated that the only physiological responses showed significant difference was the ventilatory equivalent for carbon dioxide (Veq/CO2) during the 85% exercise intensity. Although all the physiological responses were similar between Oral Breathing Trial and Nasal Breathing Trial, but for overall, Oral Breathing Trial had higher values in all the physiological responses. In conclusion, both breathing modes did not showed any differences when involving in cycling exercise.
