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 Intermittent Swimming Improves Cardiovascular Health Status for Women with Mild Hypertension
To test the hypothesis that high-intensity swim training improves cardiovascular health status in sedentary premenopausal women with mild hypertension , sixty-two women were r and omized into high-intensity ( n = 21 ; HIT ) , moderate-intensity ( n = 21 ; MOD ) , and control groups ( n = 20 ; CON ) . HIT performed 6 - 10 × 30 s all-out swimming interspersed by 2 min recovery and MOD swam continuously for 1 h at moderate intensity for a 15-week period completing in total 44 ± 1 and 43 ± 1 sessions , respectively . In CON , all measured variables were similar before and after the intervention period . Systolic BP decreased ( P < 0.05 ) by 6 ± 1 and 4 ± 1 mmHg in HIT and MOD ; respectively . Resting heart rate declined ( P < 0.05 ) by 5 ± 1 bpm both in HIT and MOD , fat mass decreased ( P < 0.05 ) by 1.1 ± 0.2 and 2.2 ± 0.3 kg , respectively , while the blood lipid profile was unaltered . In HIT and MOD , performance improved ( P < 0.05 ) for a maximal 10 min swim ( 13 ± 3 % and 22 ± 3 % ) , interval swimming ( 23 ± 3 % and 8 ± 3 % ) , and Yo-Yo IE1 running performance ( 58 ± 5 % and 45 ± 4 % ) . In conclusion , high-intensity intermittent swimming is an effective training strategy to improve cardiovascular health and physical performance in sedentary women with mild hypertension . Adaptations are similar with high- and moderate-intensity training , despite markedly less total time spent and distance covered in the high-intensity group
