Exercise Physiology Abstract: Vascular Function Study

This report presents an abstract from an exercise physiology study comparing high-intensity interval training (HIIT) with moderate-intensity continuous training (MICT) on vascular function. The study, a systematic review and meta-analysis, examined the effects of HIIT and MICT on brachial artery flow-mediated dilation. The researchers searched PubMed, MEDLINE, and Embase databases and analyzed seven randomized trials involving 182 patients. The results indicated that HIIT was more effective than MICT in improving brachial artery function. The abstract details the methods, including the HIIT protocols and the meta-analysis approach. It also includes a critique of the study and discusses the clinical applications of the findings, such as the potential of HIIT to positively influence factors related to vascular health. The study concludes that HIIT offers significant benefits for vascular function compared to MICT.

The Impact of High-Intensity Interval Training Versus Moderate-Intensity Continuous Training
on Vascular Function: A Systematic Review and Meta-Analysis
Purposes
The purpose of the study was to perform a systematic review of the evidence and quantification
of High- intensity internal training on vascular function in comparison with moderate-intensity
continuous training
Method
PubMed, MEDLINE, Embase are the three electronic databases that were searched (latest May
2014) for the purposes of attempts that randomly aimed at comparing the effect of HIIT and
MICT on vascular function for two weeks. HIIT protocols involved aerobic exercises that were
predominantly carried out with high intensity, combined with passive and active time of
recovering. Comparison of the differences in mean (vascular function assessed through brachial
artery flow-mediated dilation from the bottom to post intervention between HIIT and MICT)
was done through a meta-analysis. The HIIT versus MICT impact on CRF, risk factors to CVD,
and biomarkers connected to vascular function was also reviewed across various studies.
Markers included insulin resistance, inflammation and oxidative.

Results
The randomized attempts totaled to seven and they involved one hundred and eighty-two patients
who met the criterion of eligibility for meta- analysis. A frequently used prescription for HIIT
was 4 min (4 × 4 HIIT) of four intervals at 85–95 percent of maximum or peak heart rate
(HRmax/peak), combined with active recovery time of 3 minutes at 60–70 percent HRmax/peak, 3
times for every week in a period of 12–16 weeks. Percentage of 4.31 and 2.15 % was the
improvement percentage in the brachial artery FMD.
Conclusion
Compared to MICT, HIIT proves to be more effective in the improvement of functioning
brachial artery, which could be because of its ability to positively influence the factors above.
Critique
The information is educating, it is recognizable that different databases have shown
congruency in their studies concerning the high intensity exercises. The method for review is
appropriate and the databases are reliable that makes us believe that the information is not
biased.
Clinical application
MICT and HIIT results in significant reductions in weight, BMI, fat percentage, chloral and
improvement in VO2 max.
