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 ) .
Enjoyment for High-Intensity Interval Exercise Increases during the First Six Weeks of Training: Implications for Promoting Exercise Adherence in Sedentary Adults
This is the first study to show that enjoyment for high-intensity interval exercise increases with chronic training . Prior acute studies typically report high-intensity interval training ( HIT ) as being more enjoyable than moderate continuous training ( MCT ) unless the high-intensity intervals are too strenuous or difficult to complete . It follows that exercise competency may be a critical factor contributing to the enjoyment of HIT , and therefore building competency through chronic training may be one way to increase its enjoyment . To test this , we r and omly assigned sedentary young adults to six weeks of HIT or MCT , and tracked changes in their enjoyment for the exercise . Enjoyment for HIT increased with training whereas enjoyment for MCT remained constant and lower . Changes in exercise enjoyment were predicted by increases in workload , suggesting that strength adaptions may be important for promoting exercise enjoyment . The results point to HIT as a promising protocol for promoting exercise enjoyment and adherence in sedentary young adults
