EFFECTS OF SPRINT INTERVAL EXERCISE ON POST -FEEDING EXCESS FATS IN THE BLOOD IN WOMEN AT RISK FOR METABOLIC SYNDROME – 2015


Eric Christopher Freese , M. Evans et al
AIM
– Individuals with the metabolic syndrome (MetS) exhibit elevated postprandial (post-feeding) lipemia or excess fats in the blood (PPL)
– The aims of this investigation were to determine:
(1) if an acute bout of sprint interval training (SIT) attenuates PPL
(2) if the attenuation of PPL following 6-wks of SIT is magnified compared to a single session of SIT prior to training in women at-risk for MetS (n=45; 30-65 yrs)
DESIGN
– Women were randomized to SIT (n = 22) or a non-exercise control (n=23; CON) for 6-weeks
– Postprandial responses to a high-fat meal challenge (HFMC) were assessed prior to (Pre-HFMC) and after the 6-week intervention (Post-HFMC):
(1) CON group before (B-HFMC) and after (Post-HFMC) without prior exercise
(2) SIT group at baseline (B-HFMC) without prior exercise, after an acute bout of SIT (four 30-s all-out sprints with 4-min recovery)
RESULTS
(1) SIT before (Pre-HFMC) and after the 6-weeks (Post-HFMC) significantly attenuated fasted TG and postprandial TG responses
(2) There was no difference in fasted or tAUC TG responses between Pre-HFMC and Post-HFMC
CONCLUSIONS
(1) SIT is an effective mode of exercise to reduce fasted and postprandial TG concentrations in women at-risk for MetS
(2) 6 weeks of SIT does not magnify the attenuation (reduction) of PPL in response to a single session of SIT

NOTE: Post-Prandial means after feeding and Lipemia is defined as excess lipids or fats in the blood – Source
