High aerobic capacity has been shown to be a key indicator of physical performance in field based athletes. From having the ability to maintain energy production during long duration activities as well as replenishing other metabolic systems, aerobic capacity is a necessity for athletes performing at high levels. This research set out to look at two different training modalities in improving aerobic capacity in an athletic population. Thirteen participants (9 males and 4 females, 22.1 ± 2.5 years; 171.9 ± 10.0 cm; 74.4 ± 11.3 kg) completed six-weeks of aerobic training three times per week in either High-intensity interval training (120% of VO[subscript 2max]) or Sprint interval training (all out). In this study six participants were in the High intensity Interval group and seven were in the Sprint Interval group. Participants completed an aerobic capacity test pre and post training on a high-speed treadmill in which, VO[subscript 2max], percentage of VO[subscript 2max] at Ventilatory Threshold (VT), VO[subscript 2] at VT, and Fast Slope of Excess Post Exercise Oxygen Consumption (EPOC) were all measured used open circuit spirometry. Following six-weeks of training significant Time main effects were observed for VO[subscript 2] at VT (Pre 30.0 +/- 2.4 mL/kg/min, Post 32.4 +/- 3.0 mL/kg/min), and Fast Slope of EPOC Recovery (Pre 21.7 +/- 3.5 mL/kg/min, Post 23.5 +/- 3.8 mL/kg/min), over the six-week training period. Due to a small sample size, interpretation of this data should be made with caution. However, these findings suggest that HIIT and SIT methodologies do not differ in their impact on adaptations to aerobic performance variables over a six week intervention period. More data collection is necessary to allow for more complete interpretation with appropriate statistical power.

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.

Too much exercise can kill you. The Haywire Heart is the first book to examine heart conditions in athletes. Intended for anyone who competes in endurance sports like cycling, triathlon, running races of all distances, and cross-country skiing, The Haywire Heart presents the evidence that going too hard or too long can damage your heart forever. You’ll find what to watch out for, what to do about it, and how to protect your heart so you can enjoy the sports you love for years to come. The Haywire Heart shares the developing research into a group of conditions known as “athlete’s heart”, starting with a wide-ranging look at the warning signs, symptoms, and how to recognize your potential risk. Leading cardiac electrophysiologist and masters athlete Dr. John Mandrola explores the prevention and treatment of heart conditions in athletes like arrhythmia, atrial fibrillation and flutter, tachycardia, hypertrophy, and coronary artery disease. He reviews new research about exercise intensity and duration, recovery, inflammation and calcification, and the ways athletes inflict lasting harm. These heart problems are appearing with alarming frequency among masters athletes who are pushing their bodies harder than ever in the hope that exercise will keep them healthy and strong into their senior years. The book is complete with gripping case studies of elite and age-group athletes from journalist Chris Caselike the scary condition that nearly killed cyclist and coauthor Lennard Zinnand includes a frank discussion of exercise addiction and the mental habits that prevent athletes from seeking medical help when they need it. Dr. Mandrola explains why many doctors misdiagnose heart conditions in athletes and offers an invaluable guide on how to talk with your doctor about your condition and its proven treatments. He covers known heart irritants, training and rest modifications, effective medicines, and safe supplements that can reduce the likelihood of heart damage from exercise. Heart conditions affect hardcore athletes as well as those who take up sports seeking better health and weight loss. The Haywire Heart is a groundbreaking and critically important guide to heart care for athletes. By protecting your heart now and watching for the warning signs, you can avoid crippling heart conditions and continue to exercise and compete for years to come.

In light of the current global prevalence of overweight and obesity, the associated health risks, and the continuing adoption of sedentary lifestyle, this thesis investigated some of the factors that contribute to exercise adherence, directly comparing high-intensity whole body interval training and continuous endurance training. 68 inactive university aged adults (Age: 21.4±3.4 yrs, BMI: 25.6±4.6 kg/m2, VO2peak 40.1±5.7 ml/kg/min) were randomized into one of three groups; a non-exercise control, whole body high intensity training, or continuous endurance training. Aerobic capacity measurements, time to completion trials, muscular endurance, and core strength measures were taken at pre, post and follow up testing sessions. Psychological questionnaires were also administered during exercise as well as throughout the study. Following the intervention both exercise groups demonstrated equivalent improvements in aerobic performance, with only the interval group experiencing improved muscular and core endurance. After the 2-month follow up testing sessions the interval group lost all aerobic and core adaptation, with endurance only experiencing a partial loss. This finding indicates that the interval group did not adhere to exercise at a level that was high enough to preserve the adaptations associated with training. This finding is further supported by the psychological factors measured throughout this study, including acute affect, enjoyment and intentions to engage in future exercise.

Finally, the solution to the #1 reason we don’t exercise: time. Everyone has one minute. A decade ago, Martin Gibala was a young researcher in the field of exercise physiology—with little time to exercise. That critical point in his career launched a passion for high-intensity interval training (HIIT), allowing him to stay in shape with just a few minutes of hard effort. It also prompted Gibala to conduct experiments that helped launch the exploding science of ultralow-volume exercise. Now that he’s the worldwide guru of the science of time-efficient workouts, Gibala’s first book answers the ultimate question: How low can you go? Gibala’s fascinating quest for the answer makes exercise experts of us all. His work demonstrates that very short, intense bursts of exercise may be the most potent form of workout available. Gibala busts myths (“it’s only for really fit people”), explains astonishing science (“intensity trumps duration”), lays out time-saving life hacks (“exercise snacking”), and describes the fascinating health-promoting value of HIIT (for preventing and reversing disease). Gibala’s latest study found that sedentary people derived the fitness benefits of 150 minutes of traditional endurance training with an interval protocol that involved 80 percent less time and just three minutes of hard exercise per week. Including the eight best basic interval workouts as well as four microworkouts customized for individual needs and preferences (you may not quite want to go all out every time), The One-Minute Workout solves the number-one reason we don’t exercise: lack of time. Because everyone has one minute.

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.

Interval training has become an essential component of endurance training programs because it can facilitate a substantial improvement in endurance sport performance. Interval training involves repeated bouts of high intensity exercise lasting from seconds to minutes in duration. There remains a lack of consensus concerning the optimal method to structure an interval training program. Therefore, the objective of this thesis is to determine the optimal method to program interval training to maximize endurance sport performance. The results of this thesis showed that interval training produced adaptations in the central and peripheral factors that influence maximal oxygen consumption (VO2max) that were dependent on the type of interval training. Interval training programs led to improvements in VO2max, maximal aerobic power and time-trial (TT) performance. The responses were highly dependent on individual and training characteristics. Training status was shown to be the primary baseline characteristics that influenced the response to interval training. With respect to programming variables, long duration intervals (4 min to 5 min) performed during high-intensity interval training (HIIT) produced greater improvements in TT performance compared to sprint interval training (SIT). Exercise performed at any intensity within the severe domain led to similar improvements in TT performance. Consistent training for at least 4-weeks was required to see maximal improvements with HIIT. However, the relationship between total work and performance improvements was not present with SIT. Meta-analyses are highly effective tools that can be used to create best practice guidelines for programming interval training.

"The purpose of this study was to compare a running based High Intensity Interval Training (HIIT) protocol to a Continuous Endurance Training (CET) and their aerobic adaptations, such as increased VO2[subscritp max] and improved body composition. Recruitment of participant's occured by flyers on campus. After indicating interest, volunteers answered no, to all questions on the PAR-Q to be eligible. Pre and post testing included a submaximal VO2[subscritp max] test, using the 12 min cooper run test, and body composition using the BOD POD GS (COSMED USA Inc., Concord, California). After testing, the participants were randomly stratified based on matched aerobic capacity scores to either the HIIT, CET or control group. The CET and HIlT group completed 6 weeks of 3 days/week of the training protocol. The HIlT group did 10 X 60 s workload intervals with 60 s of rest in between each interval. The CET group did 40 to 60 min moderate intensity running. Pre to post test values were compared using a student t test with p

In the past, 'traditional' moderate-intensity continuous training (60-75% peak heart rate) was the type of physical activity most frequently recommended for both athletes and clinical populations (cf. American College of Sports Medicine guidelines). However, growing evidence indicates that high-intensity interval training (80-100% peak heart rate) could actually be associated with larger cardiorespiratory fitness and metabolic function benefits and, thereby, physical performance gains for athletes. Similarly, recent data in obese and hypertensive individuals indicate that various mechanisms - further improvement in endothelial function, reductions in sympathetic neural activity, or in arterial stiffness - might be involved in the larger cardiovascular protective effects associated with training at high exercise intensities. Concerning hypoxic training, similar trends have been observed from 'traditional' prolonged altitude sojourns ('Live High Train High' or 'Live High Train Low'), which result in increased hemoglobin mass and blood carrying capacity. Recent innovative 'Live Low Train High' methods ('Resistance Training in Hypoxia' or 'Repeated Sprint Training in Hypoxia') have resulted in peripheral adaptations, such as hypertrophy or delay in muscle fatigue. Other interventions inducing peripheral hypoxia, such as vascular occlusion during endurance/resistance training or remote ischemic preconditioning (i.e. succession of ischemia/reperfusion episodes), have been proposed as methods for improving subsequent exercise performance or altitude tolerance (e.g. reduced severity of acute-mountain sickness symptoms). Postulated mechanisms behind these metabolic, neuro-humoral, hemodynamics, and systemic adaptations include stimulation of nitric oxide synthase, increase in anti-oxidant enzymes, and down-regulation of pro-inflammatory cytokines, although the amount of evidence is not yet significant enough. Improved O2 delivery/utilization conferred by hypoxic training interventions might also be effective in preventing and treating cardiovascular diseases, as well as contributing to improve exercise tolerance and health status of patients. For example, in obese subjects, combining exercise with hypoxic exposure enhances the negative energy balance, which further reduces weight and improves cardio-metabolic health. In hypertensive patients, the larger lowering of blood pressure through the endothelial nitric oxide synthase pathway and the associated compensatory vasodilation is taken to reflect the superiority of exercising in hypoxia compared to normoxia. A hypoxic stimulus, in addition to exercise at high vs. moderate intensity, has the potential to further ameliorate various aspects of the vascular function, as observed in healthy populations. This may have clinical implications for the reduction of cardiovascular risks. Key open questions are therefore of interest for patients suffering from chronic vascular or cellular hypoxia (e.g. work-rest or ischemia/reperfusion intermittent pattern; exercise intensity; hypoxic severity and exposure duration; type of hypoxia (normobaric vs. hypobaric); health risks; magnitude and maintenance of the benefits). Outside any potential beneficial effects of exercising in O2-deprived environments, there may also be long-term adverse consequences of chronic intermittent severe hypoxia. Sleep apnea syndrome, for instance, leads to oxidative stress and the production of reactive oxygen species, and ultimately systemic inflammation. Postulated pathophysiological changes associated with intermittent hypoxic exposure include alteration in baroreflex activity, increase in pulmonary arterial pressure and hematocrit, changes in heart structure and function, and an alteration in endothelial-dependent vasodilation in cerebral and muscular arteries. There is a need to explore the combination of exercising in hypoxia and association of hypertension, developmental defects, neuro-pathological and neuro-cognitive deficits, enhanced susceptibility to oxidative injury, and possibly increased myocardial and cerebral infarction in individuals sensitive to hypoxic stress. The aim of this Research Topic is to shed more light on the transcriptional, vascular, hemodynamics, neuro-humoral, and systemic consequences of training at high intensities under various hypoxic conditions.

High-intensity training has been shown to be a time efficient way to improve physical fitness in young, healthy adults. Limited evidence and application exists in older adults, particularly those with increased risk of an exercise-related complication due to existing chronic disease. PURPOSE: To determine whether high-intensity resistance and sprint-cycle interval training are safe for moderate- to high-risk older adults and whether they impart greater health and functional improvements than the current older adult exercise recommendations. METHODS: Forty-eight participants completed 3 days/week of exercise training for 6 weeks. Participants were randomly assigned to one of three treatment conditions: 1) high-intensity sprint interval cycle training (HIIT); 2) high-intensity resistance training (HIRT); or 3) moderate-intensity continuous exercise (MICE; active control). Baseline and post-intervention measures included maximal aerobic capacity (VO2max), body composition, functional movement screen (FMS), floor-transfer-time, timed-up-and-go (TUG), perceived mobility, handgrip dynamometry, balance, and flexibility. RESULTS: VO2max significantly improved in all three exercise groups (HIIT 2.2±0.3; HIRT=3.5±0.7; MICE 2.1±0.5, P
