| METABOLIC RESPONSE OF MEN TO LOWER VS. UPPER AND LOWER BODY ROWING J.J. Mayo, L. Kravitz, J. Alvarez, and K.P. Honea Rowing is currently experiencing a resurgence of popularity as a recreational physical activity. One manufacturer (Bowflex®) has introduced an exercise device that allows for lower body only (LB) as well as upper and lower body rowing (U+LB). The metabolic responses to these variations is unclear. Therefore, the purpose of this investigation was to compare the physiological responses of LB to U+LB at two different workout cadences (66 b/min and 75 b/min). Fifteen healthy male subjects (age = 26.7 ± 7.1 yrs; wt = 82.5 ± 11.0 kg) completed four randomized submaximal rowing trials (5 min each for U+LB75, U+LB66, LB75, LB66). Oxygen consumption (VO2), ventilation (VE), respiratory exchange ratio (RER), and heart rate (HR) were monitored continuously. MANOVA with repeated measures revealed a significant (p < .0001) within group effect for all dependent variables. Results suggest that greater physiological responses to submaximal rowing are the result of increased rowing cadences and the amount of active muscle mass involved (U+LB vs. LB) during the exercise |
