The rate of obesity and its adverse health consequences have continued to rise in the past several decades. Aerobic constant load exercise is recommended to reduce excess body mass, however the effects of constant load exercise on oxygen consumption (VO2) and knee joint mechanics are inconsistent when varying weight-status strategies are employed. The purpose of this study was to assess the influence of different weight classification strategies on VO2 and knee joint mechanics during constant load exercise. Participants walked on an instrumented treadmill at a self-selected speed for 30-minutes while gait mechanics and VO2 measures were determined. Between-group differences were assessed using BMI ≥ 25, BMI ≥ 30, %Fat, and the fat free mass index. Our results show that the methodology used to categorize individuals into healthy and at-risk weight is important and impacts the findings of the effects that constant load exercise has on oxygen consumption and knee joint mechanics. Determination of an optimal methodology to assess the impact of obesity on VO2 and knee joint mechanics during constant load exercise is important for developing aerobic exercise programs for at-risk weight individuals whose goal is to reduce excess body mass to improve cardiorespiratory and joint health.
