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 .
Hemostatic and inflammatory markers in obese youths: effects of exercise and adiposity.
OBJECTIVES To determine the relation of hemostatic markers to cardiovascular fitness and adiposity and the effect of physical training ( PT ) on these markers . STUDY DESIGN Seventy-four obese teenagers were r and omly assigned to 8 months of lifestyle education ( LSE ) , LSE plus moderate-intensity PT , or LSE plus high-intensity PT . Measures included fibrinogen , plasminogen activator inhibitor-1 ( PAI-1 ) , D-dimer , C-reactive protein ( CRP ) , fitness , percent body fat ( % BF ) , and visceral adiposity ( VAT ) . RESULTS At baseline , fibrinogen and CRP were significantly correlated with % BF and VAT ( 0.27 < /= r < /= 0.51 ) , and fitness ( r = -0.39 , r = -0.43 , respectively ) ; PAI-1 with % BF ( r = 0.30 ) and VAT ( r = 0.48 ) ; D-dimer with fitness ( r = -0.24 ) . Although PT produced significant changes in fitness and adiposity , there were no significant group differences in the hemostatic markers . Change in PAI-1 was significantly correlated with its baseline value ( r = -0.47 ) and change in % BF ( r = 0.38 ) . Changes in D-dimer and CRP were significantly correlated with their respective baseline values ( r = -0.68,r = -0.48 , respectively ) . CONCLUSIONS Unfavorable levels of fitness and adiposity were associated with higher levels of hemostatic markers , putting individuals with this profile at greater risk for future cardiovascular disease . No evidence was provided that 8 months of PT had a direct influence on these markers in obese youths
