TRAINED RUNNERS DO NOT CHANGE AEROBICALLY WHEN USING NASAL STRIPS
Resaland, G. K. Aasen, S. B., & Hallen J. (2001). External nasal strips do not alter cardio-respiratory response during submaximal and maximal exercise. Medicine and Science in Sports and Exercise, 33(5), Supplement abstract 338.
Male endurance trained athletes (N = 8) performed submaximal and maximal treadmill runs under three conditions: a) mouthpiece and noseclip, b) facemask and nasal strip, and c) face mask only.
No significant differences for VO2max were found between the three conditions at either exercise intensity. There were also no changes in heart rate, ventilatory frequency, respiratory quotient, and oxygen saturation. Ventilation was significantly lower in the mouthpiece plus noseclip condition.
Implication. Nasal strips offer no physiological benefits during submaximal or maximal effort levels in trained runners.
