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
How to improve exercise performance capacity through adequate nutrition Nutrition is one of the key factors that modulate exercise performance. In this book, a group of expert scientists discuss the ergogenic properties of various nutritional interventions and present research to show that dietary strategies can be applied to extend the limits of human endurance, lower the risk of illness or injury, and speed recovery rates. More specifically, they discuss recent findings on topics such as caffeine and its effect on the brain, carnitine and fat oxidation, ergogenic properties of beta- alanine, dietary protein and muscle reconditioning, nutrition and immune status, and the importance of proper hydration. This publication will provide the reader with many novel insights into the complex interaction between nutrition and exercise, allowing them to define more effective dietary strategies to improve health and performance. Moreover, while focusing on elite athletes, it is interesting to note that some of the discoveries can be applied beyond this niche, for example to improve performance outcomes in the elderly.

Book Description
The aim of this study was to investigate the correlation between improvements in aerobic and anaerobic power with various acute physiological responses, including blood lactate accumulation (HLa), percent heart rate reserve (%HRR), Rating of Perceived Exertion (RPE), session RPE (sRPE), and the training impulse (TRIMP) during high intensity interval training (HIIT) compared to moderate intensity interval training and continuous training. Fifty-five subjects aged 18 to 29 completed a pre and post VO2max and Wingate test on the cycle ergometer. Subjects completed 24 sessions of either a steady-state exercise control at 90% of the power output (PO) at the ventilatory threshold (VT), a Meyer interval protocol with 30:60 seconds exercise-to-rest ratio at 100% of peak power output (PPO), or a Tabata interval protocol with 20:10 seconds exercise-to-rest ratio at 170% of VO2max.

Book Description
Author's abstract: Recent data collected on college-aged females indicates that more females are classified as insufficiently active and may have little time for physical activity (Ligouri, et al., 2011). High intensity interval training (defined as very short intense intervals, usually above 85% maximum heart rate accompanied by alternated passive recovery periods; HIIT) has become a popular alternative to the more traditional continuous training utilized by individuals due to its time efficiency. In fact, HIIT has been shown to induce many of the same physiological changes as moderate intensity training with less training time. It is possible that college-aged females may benefit from HIIT and its inherent time-saving qualities. To test this hypothesis, this study sought to determine the influence of a HIIT protocol on general motives for being physically active and intentions for future HIIT behaviors. Participants included sixty five female students between the ages 18 and 25 who were enrolled in a physical activity class that included HIIT as a part of the curriculum. Physiological responses to the HIIT protocol were measured via exercise intensity (as measured by heart rate) and calories burned, while motives and intentions were measured through questionnaires. Results revealed no changes in any variables over the course of the study with the exception of blood pressure. Fitness was the only variable that significantly predicted intentions for exercise and thus future2 exercise behaviors. These results show some promise for HIIT in this young population but the nature of the relationship between motives and intentions call for future research to determine why more intrinsic motives, including competence, were not related to intentions to HIIT in order to promote long term adherence to exercise programs.

Book Description
Poor diet and exercise adherence is resulting in the rise of chronic diseases. High intensity interval training (HIIT) has the ability to improve adherence as it takes less time to complete and has changes in intensity and monotony. The aim of the study was to analyze whether participants prefer HIIT in comparison to continuous aerobic exercise (CON). The hypothesis was that HIIT would be preferred and enjoyed more than CON both during and following the exercises. Participants were men and women (n=14) between the age of 30-55 years with a BMI of 25-35 kg/m2. Participants completed three exercise conditions: CON) a 45 minute walk at 60% of age predicted maximal heart rate (APMHR), HIIT60) a 20 minute HIIT exercise in which the speed and incline was changed between a high intensity of 80% APMHR and 60% APMHR every 60 seconds for a total of 10 cycles, and HIIT90) a 21 minute HIIT exercise in which the speed and incline was changed between a high intensity of 80% APMHR and 60% APMHR every 90 seconds for a total of 7 cycles. Heart rate (HR), exercise enjoyment during the exercise as measured by the exercise enjoyment scale (EES), and ratings of perceived exertion (RPE) were collected at multiple time points during the exercise. Five minutes of post exercise oxygen consumption was measured immediately and 30 minutes following the exercise sessions. General feelings as measured by the feeling scale (FS) and physical activity (PA) enjoyment as measured by the physical activity enjoyment scale (PACES) was measured 5 minutes and 35 minutes following the exercise sessions. HR and RPE were both higher in HIIT60 and HIIT90 compared to CON. In task exercise enjoyment was not higher between conditions. PA enjoyment was higher in both HIIT60 and HIIT90 compared to CON 5 minutes following the exercises. General feelings in HIIT60 was the only condition to increase 35 minutes compared to 5 minutes following the exercise. We conclude that HIIT is a more preferred exercise than CON as shown by higher preferences for HIIT90 and HIIT60 as well as higher ratings of post exercise PA enjoyment.
