Acute High-Intensity Interval Cycling Improves Postprandial Lipid Metabolism

Abstract

Acute MICE improved glucose and insulin metabolism immediately after exercise. However, HIIE performed in the evening exerts more favorable effects than MICE for decreasing postprandial insulin and triglyceride levels and increasing fat oxidation in the next morning.

Cardiometabolic Response to a Single High-intensity Interval Exercise Session Versus Breaking up Sedentary Time with Fragmented High-intensity Interval Exercise

“…A HIIE session that was volume, intensity and duration-matched to the PA breaks reduced postprandial triglyceride concentrations, potentially because the timing of the exercise provided scope for a greater rise in lipoprotein lipase activity compared with the PA breaks condition where the same volume of PA was not reached until 4 h later. Indeed, cycling and whole-body HIIE sessions performed in the evening lowered postprandial triglyceride concentrations the following morning [23,37]. There was a medium effect for postprandial glucose concentrations being lower in the PA breaks conditions than the HIIE condition in our study.…”

“…A 20-min HIIE session of 10 x 60 s cycling at 90% maximum heart rate suppressed 24 h continuous glucose concentrations in people with T2D [17]. When the postprandial assessment occurred the morning after a HIIE session, postprandial triglyceride concentrations were suppressed by sprint interval exercise (SIE) [11,34] and by 10 x 60 s cycling at 85% peak oxygen uptake [23]. However, it is unknown whether performing this type of PA spread across the day is beneficial.…”

Systematic review of the acute and chronic effects of high-intensity interval training on executive function across the lifespan

“…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.…”

The Effects of a Single Versus Three Consecutive Sessions of Football Training on Postprandial Lipemia: a Randomized, Controlled Trial in Healthy, Recreationally Active Males

“…Evidence shows as short as 3 min of high-intensity exercise to be potent enough to have benefits on metabolic profile [28], while Freese et al [23] demonstrated four 30 s all-out sprints reduced postprandial triglyceride concentration. Moreover, performing high-intensity exercise has shown to produce lower fasted and postprandial TG as well as elevated postprandial fat oxidation, compared to moderate intensity [29, 30]. A possible mechanism may be the contraction-induced increases in muscle LpL that are specific to fast-twitch fibers [31].…”
