o ANOVA was used to analyze the data collected was used to understand the difference between group and time in all subjects. Figure 1. Shows a study flowchart

KINE-4310-01 Melissa Mendoza Dr. Conatser March 26, 2020 The training load was heavier in the HIIT program leading to the average RPE and heart rate being also high in the HIIT program. Table 3. Changes in blood pressure from pre- and post-test. Significant changes were made in the systolic blood pressure where both the HIIT and MICT groups had an improvement from the pre to post-tests. Diastolic had no significant difference for both groups.

KINE-4310-01 Melissa Mendoza Dr. Conatser March 26, 2020 Results & Discussion (talk about the overall differences and or relationships within and/or between subjects and what were the major finding in the study) The study compared the effects of HIIT and MICT workout programs focusing on heart rate variability on physically inactive adults. The trainings consisted of eight sessions in a period of two weeks. The HIIT program was relatively longer to perform and had a higher heart rate, rate of perceived exertion, and the time and number training load was higher. Both programs showed an improvement in the systolic blood pressure and the time domains of the heart rate variability data. Low frequency and high frequency ratios only had a significant improvement on the high intensity interval trainings. High blood pressure is correlated through broad research to be a factor of cardiovascular diseases. The disease is preventable and individuals who perform a sedentary lifestyle are more prone to this type of diseases. o As a result of this research, in the short period of two weeks where the participants had eight sessions of training. Exercise helps improve the subjects blood pressure due to the heart being able to apply less pressure when pumping blood. It is very important to consider doing any type of exercise because it can help maintain your cardiovascular risk at a low risk while benefiting the physical health of the individual. o The systolic pressure of the subjects decreased drastically in the short-term of two weeks for both MICT and HIIT programs where it shows the importance of maintaining an active life. Another study was mentioned in this article where they were testing it had the same mechanism but with a different method of training. It has been shown in the other study that HIIT and MICT programs also improved systolic blood pressure.
