Postprandial lipoprotein profile in two modes of high-intensity intermittent exercise

Abstract

The aim of present study was to compare blood lipid postprandial profile response in two modes of high-intensity intermittent exercise. Twelve individuals (6 men and 6 women) were submitted to a maximal incremental test (to determine maximal aerobic power [MAP] and V. O2peak [peak oxygen uptake]), high-intensity intermittent all-out exercise (60×8-sec bouts interspersed by 12-sec passive recovery) and fixed high-intensity intermittent exercise (100% maximal aerobic speed, consisted of 1-min repetitions at MAP [70 rpm] separated by 1-min of passive recovery). Blood samples were collected pre, immediately, 45 and 90-min postexercise. Serum was analyzed for total cholesterol and its ratio, high-density lipoprotein cholesterol (HDL-c), low-density lipoprotein cholesterol (LDL-c), very low-density lipoprotein (VLDL) cholesterol, and triacylglycerol (TAG). For TAG there was a main effect of moment with higher values immediately postexercise compared to 45-min postexercise. For VLDL there was a main effect to moment with higher values immediately post exercise than pre and 45-min postexercise; higher values 90-min postexercise than 45-min postexercise. There was no effect for HDL-c, LDL-c, and cholesterol. For area under the curve there was no difference for any variable. Our results indicated that both kinds of acute exercise session lead to no improvement in the acute response of serum lipid profile of healthy young.

Acute cardiorespiratory, perceptual and enjoyment responses to high‐intensity interval exercise in adolescents

“…This is consistent with an adult study showing an increase in HR but no change in during the recovery intervals of HIIE in male and female middle distance runners (Tocco et al., 2015). Interestingly, we also found that boys exhibited a lower % compared to girls during recovery intervals which is similar to a study on adults employing a HIIE protocol incorporating 60 × 8‐s intervals interspersed by 12‐s of passive recovery (Panissa et al., 2016). This sex difference may be explained by the higher aerobic fitness of boys since higher aerobic fitness is associated with a faster recovery of during the recovery intervals of HIIE (Panissa et al., 2014).…”

“…However, when comparing the effect of different high-intensity training programs, Panissa et al (2016) analyzed the acute lipid profile responses mediated by two protocols of high-intensity intermittent training (all-out exercise and fixed high-intensity intermittent exercise). They concluded that both modes of exercise lead to no improvements in lipid metabolism.…”
