Maximal physiological responses between aquatic and land exercise in overweight women.

abstract：:Physiological variables must often be scaled for body size differences to permit meaningful comparisons between subjects or groups. This study aimed to determine the proper relationship between body dimensions and left ventricular mass (LVM) via allometric scaling (AS) in 142 subjects (78 males, 64 females; ages 18-40...
