In conclusion , overweight and obese youth can improve physical fitness across a variety of test measures .
When fitness improves , beneficial health effects are observed in some , but not all chronic disease risk factors
A systematic review of literature was conducted to examine the association between changes in health-related fitness ( e.g. aerobic capacity and muscular strength /endurance ) and chronic disease risk factors in overweight and /or obese youth .
Aerobic-exercise training improves ventilatory efficiency in overweight children.
The objective of this study was to investigate the effect of an 8-week aerobic-exercise training program on ventilatory threshold and ventilatory efficiency in overweight children . Twenty overweight children ( BMI > 85th percentile ) performed a grade d cycle exercise test at baseline and were then r and omly assigned to 8 weeks of stationary cycling ( n = 10 ) or a nonexercising control group ( n = 10 ) . Ventilatory variables were examined at ventilatory threshold ( VT ) , which was determined via the Dmax method . After 8 weeks , significant improvements occurred in the exercise group compared with the control group for oxygen uptake at VT ( exercise = 1.03 + /- 0.13 to 1.32 + /- 0.12 L/min vs. control = 1.20 + /- 0.10 to 1.11 + /- 0.10 L/min , p < .05 ) and ventilatory equivalent of carbon dioxide ( VE/VCO2 ) at VT ( exercise = 32.8 + /- 0.80 to 31.0 + /- 0.53 vs. control = 30.3 + /- 0.88 to 31.7 + /- 0.91 , p < .05 ) . Aerobic-exercise training might help reverse the decrements in cardiopulmonary function observed over time in overweight children
