This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Cardiovagal baroreflex sensitivity (cvBRS) is known to be influenced by endurance exercise. In fact, endurance exercisers typically display a greater cvBRS compared to sedentary controls. Despite the merits of endurance training, adherence to exercise is a problem for many individuals. High-intensity interval training (HIIT) protocols generally involve less time and work completed while imparting similar cardiovascular responses compared to endurance training. To our current knowledge, the findings of HIIT and cvBRS have been equivocal. This study investigated the effects of 12-weeks of HIIT on cvBRS and the relationship between cvBRS and measures of arterial stiffness in 16 young, healthy males. Following HIIT, cvBRS appeared to be unchanged along with most measures of arterial stiffness (carotid to femoral pulse wave velocity, common carotid artery (CCA) distensibility, and compliance); however, CCA intima-media thickness (IMT) significantly improved. Systolic blood pressure, a major determinant of cvBRS, was unchanged, while resting heart rate appeared to improve following 12-weeks of HIIT. Therefore, these findings suggest that in this sample, 12-weeks of HIIT does not appear to influence cvBRS.

This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aging is associated with a decline in peripheral vascular endothelial function [i.e., flow-mediated dilation (FMD)] and cardiovagal baroreflex sensitivity (BRS), which are both critical to cardiovascular health. Accumulating evidence in younger adults suggest that high-intensity interval training (HIIT) provides superior benefits to cardiovascular health than moderate-intensity continuous training (MICT) and whole-body resistance training (RT). We tested whether 6-weeks of HIIT (n=6) improves upper- and lower-limb FMD and BRS more than MICT (n=9) and RT (n=8) in older adults (OA). FMD was assessed via high-resolution ultrasound. Cardiovagal BRS was assessed using Portapres® derived beat-by-beat systolic blood pressures and electrocardiogram-derived cardiac intervals via the 'spontaneous baroreflex sequence' method. Short-term HIIT and MICT elicited similar increases in BRS, brachial and popliteal FMD, whereas no changes were observed following RT. These results indicate that short-term aerobic training augments vascular health and blood pressure regulation more than RT in OA.

This book was released on 2018 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: The purpose of the study was to investigate the effects of a 3-week High Intensity Interval Training (HIIT) program on fitness-related parameters (peak heart rate, peak Rating of Perceived Exertion (RPE), V ̇O2peak, time to exhaustion, and lactate threshold) among three different populations (healthy inactive, healthy active, prehypertension in China). In addition, resting blood pressure was also measured before and after the 3-week HIIT program. Males (N = 30; age = 18 - 30 years) were assigned to three groups according to the recruitment criteria. Six 2 (Time) x 3 (Group) mixed factorial ANOVAs were performed to determine if differences existed in the six dependent variables. Regardless of the group difference, significant main effects were found for systolic and diastolic blood pressure, V ̇O2peak, time to exhaustion, and lactate threshold for test occasions. No significant interaction effects were found for any variables, no significant main effects were found for peak RPE and peak heart rate. A 3-week HIIT intervention lowered resting blood pressure, while increasing time to exhaustion, lactate threshold, and V ̇O2peak for all three different groups included. Peak heart rate and peak RPE were unchanged.

This book was released on 2017 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Purpose: The study investigated the acute responses of altitude (Denver, CO) simulation during high intensity interval training and the subsequent supplementation of oxygen to facilitate greater recovery. Lacking literature on the subject matter is a major consideration for completion of the study. We hypothesize that oxygen supplementation during an acute bout of high intensity interval training with accompanying altitude will allow for greater recovery. Methods: Seven healthy cyclists aged 40.9 +/- 7.01 (Height: 68.4 +/- 4.98: Weight: 171.3 +/- 33.29: 19.3% +/-7.41%: VO2 Max L/min 4.12 +/- 1.17) performed baseline VO2max testing and three subsequent separate randomized trials consisting of three HIIT and recovery intervals with varying conditions. Session A: altitude intervals / supplemental oxygen recovery. Session B: sea level HIIT / sea level recovery. Session C: altitude HIIT / sea level recovery. Trial intensity will be established by cardiac output prediction and set at 75% HIIT and 50% recovery in watts. Results: Supplemental oxygen following HIIT elicited significant responses in HR (p

This book was released on 2023-09-08 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of microgravity on the human organism have been studied for over 60 years. The experience of short- and long-term space flights revealed alterations in multiple physiological systems either in the course of the flight or afterward. Some of these changes represent serious risks for crew health and functional capacity. This fact served as the trigger for multiple countries with space program participants to develop spaceflight countermeasures and medical support systems. These activities are intended to counteract space flight effects such as axial and support unloading, muscle disuse, monotony, fluid redistribution, sensory deficit, etc. Some countermeasures have been adapted from Earth medicine and sports, while others have been created especially for space flights. Many of the observed space flight effects have similarities to conditions seen on Earth, such as: decrease of motor activity in aging people, immobilized patients, and professions associated with forced physical inactivity and isolation. Thus, many space countermeasures and medical support systems can be applied in Earth medicine and rehabilitation. For example, countermeasures like loading suits, lower body negative pressure suits, electromyostimulation of various regimens, water-salt supplements, vestibular training means, etc. have been used in Earth medicine and sports conditioning over the last 20 years.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: High intensity interval training (HIIT) and moderate intensity continuous training (MICT) are two exercise protocols that received a great deal of attention in the field of exercise science due to their health and performance enhancing capabilities. Pulse wave velocity (PWV) and heart rate variability (HRV) have also gained traction as important indictors of health and fitness. The purpose of this study was to compare the effects that HIIT and MICT have on PWV and HRV. This was a repeated measures experimental design. Participants (N = 24) were aged 18 to 35, who self-reported that they complete 150 minutes of moderate intensity exercise or 75 minutes of vigorous intensity exercise per week. All participants completed a familiarization session which included a graded exercise test to determine their heart rate peak (HRpeak). The HIIT protocol consisted of 40 total minutes, including: 4x4 minutes at 90% or greater of HRpeak, alternated by 3x3 minutes of active recovery at 65%-75% of HRpeak, and a 10-minute warm-up and 5-minute cool-down at 65%-75% of HRpeak. The MICT protocol consisted of 47 total minutes at 65%-75% of HRpeak, including a 10-minute warm-up and 5-minute cool-down at the same intensity (Tjønna et al., 2008). Five separate 2x3 repeated measure ANOVAs were used for PWV, low frequency to high frequency (LF/HF) ratio, standard deviations of NN intervals (SDNN), root mean square of successive differences (rMSSD), and HRV score. There was a significant interaction effect of protocol and time on PWV (p = .037); however each protocol elicited differing directional changes that were non-significant. The frequency domain measure of HRV, the LF/HF ratio, decreased significantly during the HIIT protocol from 5 minutes post to 30 minutes post (p = .033). All time domains (SDNN, rMSSD, HRV score) of HRV experienced significant decreases from pre-exercise to 5 minutes post and significant increases from 5 minutes post to 30 minutes post during each protocol (p

Download or read book The Effects of High Intensity Interval Training on Resting Mean Arterial Pressure and C reactive Protein Content in Prehypertensive Subjects written by Benjamin C. Skutnik and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Subjects with prehypertension are at risk for developing hypertension (HTN). Hypertension is associated with low-grade systemic inflammation (LGSI). Aerobic exercise training (ET) is a proven means to reduce both blood pressure and LGSI in healthy and diseased subjects. Recently, high intensity interval training (HIIT) has been show to elicit similar cardiovascular and metabolic adaptations as ET in healthy and at-risk populations in a more time efficient manner. Therefore, we hypothesized that HIIT would elicit greater reductions in blood pressure and LGSI than ET. Twelve pre-hypertensive subjects (systolic blood pressure 127.0 ± 8.5 mmHg; diastolic blood pressure 86.2 ± 4.1 mmHg) were randomly assigned to an ET group (n=5) and a HIIT group (n=7). All subjects performed an incremental test to exhaustion (VO2max) on a cycle ergometer prior to, after 4 weeks, and after 8 weeks of training. Resting heart rate and blood pressure were measured prior to and three times a week during training. LGSI was measured via high-sensitivity C-reactive protein (hs-CRP) prior to, after 4 weeks and after 8 weeks of training. ET subjects performed an eight week exercise training program at 40% VO2 reserve determined from the VOVO2[subscript]max test, while HIIT subjects performed exercise at 60% peak power determined from the VO2[subscript]max test. ET group trained four days/week while HIIT trained three days/week. ET exercised for 30 minutes continuously at a constant workload and cadence of 60 rpm while HIIT performed a protocol on a 1:1 work-to-rest ratio at a constant workload and cadence of 100 rpm. Both groups showed similar (p0.05) decreases in mean arterial (ET = -7.3%, HIIT = -4.5%), systolic (ET = -6.6%, HIIT = -8.8%), and diastolic (ET= -9.7, HIIT= -8.2%) blood pressure. HIIT decreased in LGSI ( -33.7%) while ET did not change LGSI (p0.05). VOVO2[subscript]max increased ~25% with both HIIT and ET with no differences (p>0.05) between groups. These data suggest both HIIT and ET similarly decreased resting blood pressure and increased VO2max while HIIT was effective in decreasing LGSI in subjects who were pre-hypertensive.
