The purpose of this study was to determine the effect of added body weight on maximal cardiorespiratory parameters. Three athletic females performed two randomly assigned grade-incremented all-out treadmill tests, one at body weight and one with an additional 3.2 kg worn around the waist. Metabolic parameters were measured via open-circuit spirometry using an automated cart. There was no significant difference between relative VO2max (ml/kg/min) when calculated using the actual exercising body weight. However, when relative VO2max was calculated using body weight alone, the weighted treadmill VO2max was significantly higher by 5.5%. This was due to the significantly greater absolute VO2max (L/min) during the weighted test. None of the other parameters (i.e., RER, respiratory rate, VE, or Kcal/min) were significantly different. The results of this pilot study would suggest that training while carrying additional weight could have a significantly greater effect on cardiorespiratory development.
