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
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
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
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.

Book Description
Background: Time spent above 90% of maximal oxygen uptake (V?O2max) has been shown to be a valuable indicator of high-intensity interval training (HI[I]T) effectiveness. This study aimed to investigate whether variations in exercise intensity during an interval could lead to increased responses of the physiological systems associated with aerobic exercise performance. We hypothesized that a varied intensity protocol (VAR), vs. a work-matched constant intensity protocol (CON), would elicit a higher time spent above 90% V?O2max and evoke a higher skeletal muscle fractional O2 utilization/extraction, as measured by the drop in tissue saturation index (?TSI) with the NIRS technology. Materials & Methods: Nineteen participants (177.2 ± 8.9 cm, 71,7 ± 9.6 kg , 34 ± 12 years, 3687 ± 665 mL.min-1 absolute V?O2max, 51.9 ± 6.1 mL.min-1.kg-1 relative V?O2max) completed two HI[I]T protocols of 4 x 5 minutes with 3 minutes of pause in between intervals: one constant-power (CON) and one varying-power (VAR) protocol. The VAR protocol consisted of two surges at 100% of maximum aerobic power (MAP) at the beginning and the middle of the interval, interspersed with sections at 75% of MAP. The CON protocol was work-matched to the VAR protocol and ridden at a constant power output. V?O2max and maximal power output were assessed in an incremental exercise test to voluntary exhaustion. Time spent above 90% V?O2max (T>90%V?O2max) and 90%?TSImax (T>90%?TSImax) were the primary outcomes of interest. Results: For time spent above 90% V?O2max, there was no significant difference between the VAR (437.3±420.4 s) and CON (371.7±374.9 s) protocols (p > 0.05). Similarly, there was no significant difference in time spent above 90% maximal TSI drop between the VAR (397.3±402.2 s) and CON (394.3±440.4 s) protocols (p > 0.05). Conclusions: Our results did not support the hypothesis that a varied intensity protocol (VAR) would elicit a higher time spent above 90% V?O2max or higher skeletal muscle fracti

Book Description
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.
