Prediction of peak V˙O2 in Children and Adolescents With HIV From an Incremental Cycle Ergometer Test

摘要: PURPOSE To examine the capacity of physiological variables and performance to predict peak oxygen consumption (peak V˙ O2) in children adolescents living with HIV. METHOD Sixty-five HIV (30 boys) aged 8-15 years, participated study. Peak O2 was measured by breath-by-breath respiratory exchange during an incremental cycle ergometer until volitional exhaustion. Information on time exhaustion, maximal power output (Pmax), heart rate HR) were also recorded. RESULTS Predictive models developed all equations showed ability O2. However, Model 1 based only Pmax following equation: Y = 338.8302 + (Pmax [W] * 11.16435), R2 0.90 standard error estimation (SEE) 180 ml ⋅ min-1. CONCLUSION The can be predicted simply obtained from test. This protocol is a valid useful tool for monitoring aerobic fitness HIV, especially resource-limited settings.
