The results of the present arm crank study and data of lower extremity cycle exercise extracted from a previous study will be presented simultaneously in Tables 1, 2, and 3 for the convenience of comparison. Table 1 shows that there were no significant differences in the anthropometric characteristics between both groups of subjects for height, weight, and age. buy ventolin inhalers
Cardiopulmonary Data
Mean (±SEM) values for power (W), heart rate (beats/min), Vo2 (L/min), Vo/kg (L/min/kg), Vco2 (L/min), anaerobic threshold (L/min), and Ve (L/min), during peak arm crank exercise are shown in Table 2. Lower extremity cycle data at peak exercise and at a level of Vo corresponding to peak arm crank (sub-maximal cycle ergometry) have been included. Except for R, all of the values obtained during peak arm crank exercise were significantly lower than those obtained during peak lower extremity cycle exercise. However, at comparable Vo2, only Vco2, R and Ve were significantly higher for arm crank exercise.
