METHODS The results of recent systematic review s are discussed and supplemented with relevant literature not included in these review s. PubMed was search ed for the years 2006 - 2011 for additional topics not sufficiently covered by the review s. RESULTS PA was associated with lower blood pressure and a healthier lipid blood profile in children .
The association was stronger when a composite risk factor score was analysed , and the associations between physical fitness and cardiovascular disease ( CVD ) risk factors were even stronger .
Muscle strength and endurance exercise each had an effect on blood lipids and insulin sensitivity even if the effect was smaller for muscle strength than for aerobic exercise .
New evidence suggests possible effects of PA  on C-reactive protein .
CONCLUSION There is accumulating evidence that PA can have beneficial effects on the risk factors of CVD in children .
BACKGROUND A number of recent systematic review s have result ed in changes in international recommendations for children 's participation in physical activity ( PA ) for health .
The World Health Authority ( WHO ) has recently released new recommendations .
The WHO still recommends 60 min of moderate to vigorous physical activity ( MVPA ) , but also emphasises that these minutes should be on top of everyday physical activities .
Everyday physical activities total around 30 min of MVPA in the quintile of the least active children , which means that the new recommendations constitute more activity in total compared with earlier recommendations .
OBJECTIVE To summarise evidence justifying new PA recommendation for cardiovascular health in children .
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
