Book Description
The purpose of this investigation was to compare 6 high intensity interval training (HIIT) sessions with predominately continuous training (CONT) over 11 days on highly trained rowers. Two groups (n=8) completed an incremental ramp test to determine Peak Aerobic Power (PAP), and a Critical Power test (CP). HIIT sessions consisted of 10 bouts of 10 s work (140% of PAP) with 5 s recovery, followed by 8 min of active recovery; repeated 6 times. 60 s power decreased in CONT (510±167-489±171W; p=0.02). CP increased in both groups (HIIT: 336±59-360±59W; CONT: 290±73-316±74W; p≤0.05). W' decreased in CONT only (14256±7022-11303±7360J; p=0.01). Mean Power Output Measure (MPOM) (10s, 60s, CP, and PAP) showed an improvement for HIIT (464±158- 496±184W; p=0.01) vs. CONT (433±186-433±181W; p30.05). This study has demonstrated that 6 sessions of a novel HIIT protocol will increase MPOM, while maintaining anaerobic capacity compared to a predominantly CONT training protocol in elite rowers.

Book Description
The popularity of high-intensity interval training (HIIT), which consists primarily of repeated bursts of high-intensity exercise, continues to soar because its effectiveness and efficiency have been proven in use by both elite athletes and general fitness enthusiasts. Surprisingly, few resources have attempted to explain both the science behind the HIIT movement and its sport-specific application to athlete training. That’s why Science and Application of High-Intensity Interval Training is a must-have resource for sport coaches, strength and conditioning professionals, personal trainers, and exercise physiologists, as well as for researchers and sport scientists who study high-intensity interval training.

Book Description
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

Book Description
This book provides an extensive guide for exercise and health professionals, students, scientists, sport coaches, athletes of various sports and those with a general interest in concurrent aerobic and strength training. Following a brief historical overview of the past decades of research on concurrent training, in section 1 the epigenetic as well as physiological and neuromuscular differences of aerobic and strength training are discussed. Thereafter, section 2 aims at providing an up-to-date analysis of existing explanations for the interference phenomenon, while in section 3 the training-methodological difficulties of combined aerobic and strength training are elucidated. In section 4 and 5, the theoretical considerations reviewed in previous sections will then be practically applied to specific populations, ranging from children and elderly to athletes of various sports. Concurrent Aerobic and Strength Training: Scientific Basics and Practical Applications is a novel book on one of the “hot topics” of exercise training. The Editors' highest priority is to make this book an easily understandable and at the same time scientifically supported guide for the daily practice.

Book Description
The purpose of this study was to compare the effects of two high intensity interval training (HIIT) protocols and a steady-state protocol on anaerobic capacity after 8 weeks of training. Fifty-five untrained college-aged subjects (17 male, 38 female) completed this 8-week training study. The subjects were randomly assigned to one of three training protocols (steady-state, Tabata, or Meyer). The steady-state group (n=19) completed 20 minutes of exercise at 90% of ventilatory threshold. The Tabata group (n=21) completed eight intervals of 20 seconds at 170% VO2max, with 10 seconds rest in between each bout. The Meyer group (n=15) completed 30 seconds at 100% of the PPO at VO2max, with 60 seconds of active rest at an output that made the average of the intervals equal to 90% of ventilatory threshold. This was repeated 13 times for a total of 20 minutes of exercise. Each subject completed 24 sessions of their respective training protocol. Pre and post-test Wingate anaerobic tests (WAnT) were used to assess the changes in peak power output (PPO), mean power output (MPO), and rate to fatigue. There were significant improvements in PPO (steady-state=+6.7%, Tabata=+9.1%, Meyer=+4.4%), PPO/kg (steady-state=+7.8%, Tabata=+8.5%, Meyer=+5.1%), MPO (steady-state=+3.4%, Tabata=+8.1%, Meyer=+9.8%), and MPO/kg (steady-state=+4.3%, Tabata=+6.8%, Meyer=+6.1%) in all three training groups (p

Book Description
Introduction: High intensity interval training (HIIT) has become an increasingly popular exercise phenomenon due to its cardiovascular effect and short duration. The purpose of this study was to compare the effects of two HIIT protocols and a steady-state protocol on aerobic capacity following an 8-week training period. Methods: Fifty-five untrained college-aged subjects (17 male, 38 female) were randomly assigned to one of the three training groups (steady-state, Tabata, or Meyer). The steady-state group (n=19) completed 20 minutes of exercise at 90% of ventilatory threshold. The Tabata group (n=21) completed eight intervals of 20 seconds at 170% VO2max, with 10 seconds rest in between each bout. The Meyer group (n=15) completed 13 sets of 30 seconds at 100% of the PPO at VO2max, with 60 seconds of active rest, yielding an output average of 90% of ventilatory threshold. Each subject completed 24 training sessions. Results: Significant increases in VO2max and Peak Power Output for each training group, with no significant differences between groups. There were no significant changes in maximal HR for any training group over the course of the study. The results of this study suggest that steadystate, Tabata, and Meyer protocols elicit similar increases in aerobic capacity.

Book Description
Heart failure is a major worldwide health concern and is the leading cause of hospitalization among elderly Americans. Approximately 50% of those diagnosed with heart failure have heart failure with preserved ejection fraction (HFPEF). HFPEF presents a therapeutic dilemma because pharmacological strategies that are effective for the treatment of heart failure and reduced ejection fraction have failed to show benefit in HFPEF. Long term moderate intensity exercise programs have been shown to improve diastolic function in patients HFPEF. High intensity interval training (HIIT) has been shown to improve diastolic function in patients with heart failure and reduced ejection fraction. However, the effects of high intensity interval training in patients with HFPEF are unknown. Fourteen patients with HFPEF were randomized to either: (1) a novel program of high-intensity aerobic interval training (n = 8), or (2) a commonly prescribed program of moderate-intensity (MOD) aerobic exercise training (n = 6). Before and after four weeks of exercise training, patients underwent a treadmill graded exercise test for the determination of peak oxygen uptake (VO2peak), a brachial artery reactivity test for assessment of endothelium-dependent flow-mediated dilation (BAFMD), aortic pulse wave velocity assessment as an index of vascular stiffness and two-dimensional echocardiography for assessment of left ventricular diastolic and systolic function. I hypothesized that (1) high-intensity aerobic interval training would result in superior improvements in FMD, aortic pulse wave velocity, VO2peak, diastolic function and, (2) changes in these parameters would be correlated with changes in VO2peak. The principal findings of the study were that a one month long high intensity interval training program resulted in significant improvements in diastolic function as measured by two-dimensional echocardiography [pre diastolic dysfunction (DD) grade - 2.13 ± 0.4 vs. post DD grade - 1.25 ± 0.7, p = 0.03]. The left atrial volume index was reduced in the HIIT group compared to MOD ( - 4.4 ± 6.2 ml/m2 vs. 5.8 ± 10.7 ml/m2, p = 0.02). Early mitral flow (E) improved in the HIIT group (pre - 0.93 ± 0.2 m/s vs. post - 0.78 ± 0.3 m/s, p = 0.03). A significant inverse correlation was observed between change in BAFMD and change in diastolic dysfunction grade (r = - 0.585, p = 0.028) when all the data were pooled. HIIT appears to be a time-efficient and safe strategy for improving diastolic function in patients with heart failure and preserved ejection fraction. These data may have implications for cardiovascular risk reduction in this population.
