Abstract

Purpose: The purpose of this study was to determine differences in VO2max and metabolic variables between treadmill running and treadmill skating. This study also examined VO2max responses during a continuous skating treadmill protocol and a discontinuous skating treadmill protocol.

Methods: Sixteen male high school hockey players (16.6 ± .96 yrs), all above average fitness level, participated in this study. All subjects participated in three tests: I) discontinuous skating treadmill test, 2) continuous skating treadmill test, and 3) running treadmill test. The discontinuous skating treadmill and continuous skating treadmill tests were both randomized. Minute ventilation (Ve), oxygen consumption (VO2), carbon dioxide production (VCO2), respiratory exchange ratio (RER), heart rate (HR), and oxygen pulse (02 pulse) were averaged every 15 seconds up to VO2max for each exercise test. Absolute ventilatory threshold (VT), VT as a percentage ofVO2max (%), and HR (beats·min"1) and VO2 (L·min"1) pre/post breakpoint slopes were also calculated for continuous skating and treadmill running.

Results: There was a statistically significant difference (p < .05) for VO2 (ml·kg·'·min·') and VCO2 (L·min"1) between the running treadmill protocol and discontinuous skating treadmill protocol. There was also a significant difference for RER between the discontinuous and continuous skating treadmill protocol and between the discontinuous skating treadmill protocol and running treadmill protocol. There was a significant difference for HR (beats·min"1) and VOi (L·min"1) pre/post breakpoint slopes between the continuous skating protocol and treadmill running protocol. Conclusion: The running treadmill elicited a higher VOi (ml·kg"1·min·1) than the skating treadmill, but when it comes to specificity of ice skating, the skating treadmill may be ideal. Also, there was no significant difference between the discontinuous and continuous skating treadmill protocols. Therefore, a continuous protocol is possible on the skating treadmill without compromising correct skating position and physiological responses.
