“…The major influence of gender and BMI on physical fitness is a consistent association noted in studies of physical energy capacity, with females exhibiting at least 20% lower capacity than males even when the VO 2peak values are expressed as ml·kg −1 ·min −1 (McArdle, Katch, & Katch, 2001;McMurray et al, 2002). Studies of physical activity behaviors in general youth populations report decreasing levels of CE in females versus males as they age into later adolescence (Garcia et al, 1995;Myers, Strikmiller, Webber, & Berenson, 1996;Pate, Heath, Dowda, & Trost, 1996). Although no studies in youth report metabolic control of glucose level as a predictor of CE, better glycemic control has been a positive outcome of the limited intervention research that has promoted physical activity in youth with type 1 DM (Marrero et al, 1988;Mosher et al, 1998).…”
