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 ) .
Both aerobic endurance and strength training programmes improve cardiovascular health in obese adults.
Regular exercise training is recognized as a powerful tool to improve work capacity , endothelial function and the cardiovascular risk profile in obesity , but it is unknown which of high-intensity aerobic exercise , moderate-intensity aerobic exercise or strength training is the optimal mode of exercise . In the present study , a total of 40 subjects were r and omized to high-intensity interval aerobic training , continuous moderate-intensity aerobic training or maximal strength training programmes for 12 weeks , three times/week . The high-intensity group performed aerobic interval walking/running at 85 - 95 % of maximal heart rate , whereas the moderate-intensity group exercised continuously at 60 - 70 % of maximal heart rate ; protocol s were isocaloric . The strength training group performed ' high-intensity ' leg press , abdominal and back strength training .  Maximal oxygen uptake and endothelial function improved in all groups ; the greatest improvement was observed after high-intensity training , and an equal improvement was observed after moderate-intensity aerobic training and strength training . High-intensity aerobic training and strength training were associated with increased PGC-1alpha ( peroxisome-proliferator-activated receptor gamma co-activator 1alpha ) levels and improved Ca(2 + ) transport in the skeletal muscle , whereas only strength training improved antioxidant status . Both strength training and moderate-intensity aerobic training decreased oxidized LDL ( low-density lipoprotein ) levels . Only aerobic training decreased body weight and diastolic blood pressure . In conclusion , high-intensity aerobic interval training was better than moderate-intensity aerobic training in improving aerobic work capacity and endothelial function . An important contribution towards improved aerobic work capacity , endothelial function and cardiovascular health originates from strength training , which may serve as a substitute when whole-body aerobic exercise is contra-indicated or difficult to perform
