ObjectiveTo 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).DesignSystematic review and meta-analysis.Data sourcesEnglish language searches of several databases were conducted from inception until September 2019.Eligibility criteria for excluding studiesInclusion: (1) published randomised controlled human trials with group population n≥5; (2) intervention duration ≥4 weeks; (3) comparing HIIT with MICT; and (4) reporting pre–post intervention lipid measurements. Exclusion: subjects with chronic disease, <18 years, pregnant/lactating, in elite athletic training; and studies with a dietary or pharmaceutical intervention component.ResultsTwenty-nine data sets (mmol/L) of 823 participants were pooled and analysed. Neither HIIT nor MICT was better in decreasing TC (0.10 (−0.06 to 0.19), p=0.12, I2=0%), TRG (−0.05 (−0.11 to 0.01), p=0.10, I2=0%), LDL-C (0.05 (−0.06 to 0.17), p=0.37, I2=0%), or TC/HDL-C (−0.03 (−0.36 to 0.29), p=0.85, I2=0%). HIIT significantly raised HDL-C (0.07 (0.04 to 0.11), p<0.0001, I2=0%) compared with MICT.ConclusionNeither HIIT nor MICT is superior for altering TC, TRG, or LDL-C, or TC-HDL-C ratio. Compared with MICT, HIIT appeared to significantly improve HDL-C. Clinicians may prescribe either protocol to encourage participation in exercise and reduce cardiovascular risk. To raise HDL-C, HIIT may result in a larger effect size compared with MICT.PROSPERO registration numberCRD42019136722.

“…HIIT refers to physical activity characterized by relatively brief bursts of vigorous activity (i.e., ~90% of maximal aerobic power for brief intervals), interspersed by short periods of rest or low-intensity physical activity for recovery (Eddolls et al, 2017). It has been suggested that HIIT, typically studied using treadmill running or cycling on an ergometer (Eddolls et al, 2017), may be an attractive alternative to traditional moderateintensity continuous exercise or resistance exercise as a means of promoting various health outcomes, such as aerobic capacity (Lee, Hsu et al, 2018), lipid metabolism (Lee, Kuo et al, 2018), vascular function (O'Brien et al, 2020), and balance (Jiménez-García et al, 2019). Although HIIT may be associated with higher risk of injury (Rynecki et al, 2019), its health-related benefits can be manifested once implemented appropriately.…”

Research regarding the effects of high-intensity interval training (HIIT) on executive function has grown exponentially in recent years. However, there has been no comprehensive review of the current state of literature. Therefore, the aim of this systematic review is to summarize previous research regarding the acute and chronic effects of HIIT on executive function across the lifespan and highlight future research directions. The results indicated that acute bouts of HIIT has a positive effect on inhibition in children/ adolescents and adults, and further that chronic HIIT benefits inhibition and working memory in children. More research employing chronic interventions, focusing on middle-aged and older adults, and examining the effects on the working memory and cognitive flexibility domains of executive function are needed. Future research should also focus on a) the use of stronger research designs, b) the effects of HIIT dosage/modality, c) consideration of individual differences, d) possible underlying mechanisms, and e) examining the feasibility of translating HIIT to real-word settings.

“…Evidence suggests that short-term cycle ergometer interval training interventions (≤4 weeks) improve physiological markers associated with health (e.g., skeletal muscle oxidative capacity and VO 2max ) in male undergraduate students [ 13 , 22 , 23 ]. The effects of cycle ergometer interval training on body composition have also been reported [ 24 ], with a report of lower body fat percentage following 12 cycle-ergometer interval training sessions [ 24 ]. Nevertheless, the metabolic demands of the exercise modalities are different in cycling compared to running [ 25 ]; thus, previous findings cannot be generalized to run interval training (RIT).…”

Perceived lack of time is one of the most often cited barriers to exercise participation. High intensity interval training has become a popular training modality that incorporates intervals of maximal and low-intensity exercise with a time commitment usually shorter than 30 min. The purpose of this study was to examine the effects of short-term run interval training (RIT) on body composition (BC) and cardiorespiratory responses in undergraduate college students. Nineteen males (21.5 ± 1.6 years) were randomly assigned to a non-exercise control (CON, n = 10) or RIT (n = 9). Baseline measurements of systolic and diastolic blood pressure, resting heart rate (HRrest), double product (DP) and BC were obtained from both groups. VO2max and running speed associated with VO2peak (sVO2peak) were then measured. RIT consisted of three running treadmill sessions per week over 4 weeks (intervals at 100% sVO2peak, recovery periods at 40% sVO2peak). There were no differences in post-training BC or VO2max between groups (p > 0.05). HRrest (p = 0.006) and DP (p ≤ 0.001) were lower in the RIT group compared to CON at completion of the study. RIT lowered HRrest and DP in the absence of appreciable BC and VO2max changes. Thereby, RIT could be an alternative model of training to diminish health-related risk factors in undergraduate college students.

Physiological Adaptations to Sprint Interval Training with Matched Exercise Volume

Abstract: The higher incremental aerobic performance and lower skinfold thickness in HIIT60s versus HIIT10s reflected similar adaptations, but the higher repeated sprint performance was observed only in responses to HIIT60s, which may elicit greater anaerobic adaptations.
