Conclusion Neither HIIT nor MICT is superior for altering TC , TRG , or LDL-C , or TC-HDL-C ratio .
To raise HDL-C , HIIT may result in a larger effect size compared with MICT .
Objective To compare the effects of moderate intensity continuous training ( MICT ) and high intensity interval training ( HIIT ) on  adult lipid profiles ;  to identify training or participant characteristics that may determine exercise-induced change in total cholesterol ( TC ) , triglycerides ( TRG ) , high-density lipoprotein cholesterol ( HDL-C ) and low-density lipoprotein cholesterol ( LDL-C ) .
High-intensity aerobic interval training improves aerobic fitness and HbA1c among persons diagnosed with type 2 diabetes
Purpose It remains to be established how high-intensity aerobic interval training ( HAIT ) affects risk factors associated with type 2 diabetes ( TD2 ) . This study investigated effects of HAIT on maximal oxygen uptake ( VO2max ) , glycated Hemoglobin type A1C ( HbA1c ) , insulin resistance ( IR ) , fat oxidation ( FatOx ) , body weight ( BW ) , percent body fat ( % BF ) , lactate threshold ( LT ) , blood pressure ( BP ) , and blood lipid profile ( BLP ) among persons with T2D . Results were compared to the effects after a moderate-intensity training ( MIT ) program . Methods Thirty-eight individuals with T2D completed 12 weeks of supervised training . HAIT consisted of 4 × 4 min of walking or running uphill at 85–95 % of maximal heart rate , and MIT consisted of continuous walking at 70–75 % of maximal heart rate . Results A 21 % increase in VO2max ( from 25.6 to 30.9 ml kg−1 min−1 , p < 0.001 ) , and a reduction in HbA1c by −0.58 % points ( from 7.78 to 7.20 % , p < 0.001 ) was found in HAIT . BW and body mass index ( BMI ) was reduced by 1.9 % ( p < 0.01 ) . There was a tendency towards an improved FatOx at 60 % VO2max ( 14 % , p = 0.065 ) . These improvements were significant different from MIT . Both HAIT and MIT  increased velocity at LT , and reduced % BF , waist circumference , hip circumference , and BP , with no significant differences between the two groups . Correlations were found between change in VO2max and change in HbA1c when the two intervention groups were combined ( R = −0.52 , p < 0.01 ) . Conclusion HAIT is an effective exercise strategy to improve aerobic fitness and reduce risk factors associated with T2D
