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
Physiological Aspects of Sport Training and Performance, Second Edition With Web Resource, updates and expands on the popular first edition, providing an in-depth discussion of physiological adaptation to exercise. Students will learn the importance of an evidence-based approach in prescribing exercise, while sports medicine professionals and health care providers will appreciate using the text as a primary reference on conditioning and performance of athletes. A range of topics are covered, including environmental influences on performance, hydration status, sport nutrition, sport supplements, and performance-enhancing drugs. The book is focused on physiological adaptation to exercise with a goal of providing practical applications to facilitate exercise prescriptions for a variety of athletes. Physiological Aspects of Sport Training and Performance, Second Edition, is organized into five parts. The first part examines physiological adaptation and the effects of various modes of training on biochemical, hormonal, muscular, cardiovascular, neural, and immunological adaptations. The second part covers principles of exercise training and prescription. The third part discusses nutrition, hydration status, sport supplementation, and performance-enhancing drugs. The fourth part focuses on environmental factors and their influence on sport performance. The fifth and final part is focused on how certain medical and health conditions influence sport performance. Updates in this second edition focus on cutting-edge knowledge in sport science and sports medicine, including the latest information on physiological adaptations to exercise; current trends for training for power, speed, and agility; eye-opening discussions on sport supplementation and performance-enhancing drugs; data on training with medical conditions such as diabetes and exercise-induced bronchospasm; and groundbreaking information on training in heat and cold and at altitude. In addition, new chapters offer a practical approach to the yearly training program and sudden death in sport. The second edition also incorporates the following features to enhance practical application and facilitate students’ learning: • A new web resource includes 80 drills and 41 video demonstrations that help readers understand how to implement the various exercises. • Chapter objectives provide an overview of key content in each chapter. • Chapter review questions help students assess their learning. • In Practice sidebars bring chapter content to life in a practical manner and help students better understand the material. Students and instructors will benefit from the new web resource, which features 80 drills and detailed instruction on performing each drill. The drills can be used for a dynamic warm-up or to enhance speed and agility. Most drills are accompanied by at least one photo showing how to perform a key movement of the drill. Forty of the drills are accompanied by a video of the drill being performed in its entirety, and a dynamic warm-up routine video features 10 warm-up exercises. Physiological Aspects of Sport Training and Performance, Second Edition, provides a strong basis for understanding adaptation to exercise and appreciating how changes in program variables can alter training adaptations. All the information in this text is presented in an attractive, reader-friendly format that is conducive to learning. The text serves as both a key educational tool and a primary reference for exercise prescription for athletes.

Book Description
Flotation-restricted environmental stimulation therapy (flotation-REST) attenuates afferent nervous system signaling and promotes relaxation of the body and mind. Despite limited research, the intervention has become increasingly popular among high-performance populations (e.g., elite athletes, military operators) seeking to accelerate recovery and enhance performance readiness. The aim of the present investigation was to determine whether a one-hour flotation-REST session could augment recovery from high-intensity resistance exercise (6 sets of 10 back squats with 2 minutes rest) known to induce significant metabolic, adrenergic and mechanical stress. Eleven healthy resistance-trained males (age: 22.5± 2.3 years; height: 176.4±6.0 cm; weight: 85.7±6.2 kg, back squat 1RM: 153.1±20.1 kg; strength to weight ratio: 1.8±0.2) completed the within-subjects cross-over controlled research study. Following flotation-REST familiarization, participants completed two exercise testing blocks separated by a two-week washout. In one testing block, the high-intensity squat protocol was immediately followed by a one-hour flotation-REST session, while recovery in the remaining block consisted of a passive control condition in a sensory-stimulating environment. Markers of metabolic stress (lactate), neuroendocrine signaling (catecholamines, cortisol, testosterone), structural damage (myoglobin, creatine kinase), inflammation (IL-6, TNF-alpha), muscular performance (squat jump, countermovement jump) and psychological perception (pain, soreness, mood, fatigue, energy) were assessed at five time points: before exercise (PRE), immediately post-exercise (IP), post 1-hour recovery (1R), twenty-four hours post-exercise (+24) and forty-eight hours post-exercise (+48). Repeated measures analysis of variance revealed muscle soreness was significantly attenuated with flotation-REST. The greatest treatment difference was observed directly following the intervention, in which the intensity of soreness was rated 36% lower than control. The flotation-REST intervention also led to significantly greater improvements in mood state and fatigue, confirming the psychological benefits noted during initial familiarization. While significant reductions in cortisol were demonstrated during the first flotation exposure, mediation of the HPA axis was not observed following exercise. However, reductions in norepinephrine and increases in total testosterone revealed significant modification of neuroendocrine signaling pathways which may mediate positive recovery processes. Acute physiological responses to high-intensity exercise (e.g., hyperemia, HPA inhibition) may have contributed to the limited treatment effect observed in the physiological domains. However, the lack of change in structural damage and inflammatory signaling may suggest the suitability of flotation-REST for everyday use, as the modality does not appear to interfere with muscle repair and remodeling. The data reveal a positive impact of flotation-REST in the first 48 hours of recovery, particularly where psychological appraisal is involved. As no adverse effects were observed in any of the recovery domains, flotation-REST may be considered a safe and valuable intervention for promoting relaxation, managing soreness and enhancing performance readiness.

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.
