) found that VO 2 peak estimated by the PACER test tended to be overestimated in less fit participants and underestimated in more fit participants compared with VO 2 peak measured with indirect calorimetry. In addition, weight status can impact VO 2 peak prediction. Previous research has shown that the

) until volitional fatigue was reached. During the exercise test, respiratory gas exchange and energy expenditure were measured using a computerized indirect calorimetry system (TrueOne 2400; ParvoMedics, Sandy, UT). Heart rate was measured using radio telemetry (Polar ® , Kempele, Finland) that was
