Aerobic and strength training reduces adiposity in overweight Latina adolescents . PURPOSE To date , no study has examined the synergistic effects of a nutrition and combination of aerobic and strength training ( CAST ) on both adiposity and metabolic parameters in overweight Latina adolescent females . The goal was to assess if a 16-wk nutrition plus CAST pilot study had stronger effects on reducing adiposity and on improving glucose/insulin indices compared with control ( C ) , nutrition only ( N ) , and a nutrition plus strength training ( N + ST ) groups . METHODS In a 16-wk randomized trial , 41 overweight Latina girls ( 15.2 +/- 1.1 yr ) were randomly assigned to C ( n = 7 ) , N ( n = 10 ) , N + ST ( n = 9 ) , or N + CAST ( n = 15 ) . All intervention groups received modified carbohydrate nutrition classes ( once a week ) , whereas the N + ST also received strength training ( twice a week ) and the N + CAST received a combination of strength and aerobic training ( twice a week ) . The following were measured before and after intervention : strength by one repetition maximum , physical activity by the 7-d accelerometry and the 3-d physical activity recall , dietary intake by 3-d records , body composition by dual-energy x-ray absorptiometry ( DEXA ) , glucose/insulin indices by oral glucose tolerance test , and intravenous glucose tolerance test with minimal modeling . Across intervention group , effects were tested using ANCOVA with post hoc pairwise comparisons . RESULTS There were significant overall intervention effects for all adiposity measures ( weight , body mass index [ BMI ] , BMI z-scores , and DEXA total body fat ) , with a decrease of 3 % in the N + CAST group compared with a 3 % increase in the N + ST group ( P < or = 0.05 ) . There was also an intervention effect for fasting glucose with the N group increasing by 3 % and the N + CAST group decreasing by 4 % ( P < or = 0.05 ) . CONCLUSION The CAST was more effective than nutrition alone or nutrition plus strength training for reducing multiple adiposity outcomes and fasting glucose in overweight Latina girls . However , further research investigating and identifying intervention approaches that improve both adiposity and insulin indices , particularly in high-risk populations , are warranted .
