Key result
The VmaxST portable metabolic measurement system yielded similar values to the standard Vmax29 system across all measured metabolic and physiological variables (P = 0.88).

Does the VmaxST portable metabolic measurement system provide valid physiological measurements compared to the standard Vmax29 system in asymptomatic males during exercise?
p-value: p=0.88
The VmaxST portable metabolic measurement system is a valid device for measuring metabolic and physiological variables during exercise in a controlled laboratory setting.
Laurent et al. (2008) conducted a cross-sectional in Healthy (asymptomatic, moderately active) (n=30). VmaxST portable metabolic measurement system vs. Vmax29 standard measurement system was evaluated on Peak values for time to exhaustion, heart rate, blood pressure, VO2, VCO2, VE, and RER (p=0.88). The VmaxST portable metabolic measurement system yielded similar values to the standard Vmax29 system across all measured metabolic and physiological variables (P = 0.88).
