The Science and Application of High Intensity Interval Training

The Science and Application of High Intensity Interval Training

In this session from 2019 Coaches Conference, Paul Laursen, co-author of the book “Science and Application of High-Intensity Interval Training: Solutions to the Programming Puzzle,” explains the physiological targets of high-intensity interval training and how to design and manipulate variables for a variety of applications.

From the 2021 NSCA National Conference, Dr. Abbie Smith-Ryan discusses updated information, nutritional components, sex-specific considerations, and practical applications of high-intensity interval training.

From the NSCA’s 2019 Tactical Annual Training, Nathan Dicks explains the Critical Speed Concept. He presents the normative data, parameters for tactical professionals, and how it can be modeled with load carriage for use in prescribing high-intensity interval training.

Athletes in field and court sports require reactive agility—they must accelerate, decelerate, and change direction in a constantly changing environment. These requirements result in technical differences between sprinting in a field or court sport and sprinting the 100-m.

This review analyzes relevant variables involved in acute interference effects of concurrent training (CT) sessions of aerobic exercise followed by strength exercises. The aerobic exercise intensity, mode, volume, duration of recovery interval between exercises, muscle groups involved, and utilization of ergogenic aids are the variables identified in this review. High-intensity interval aerobic exercises result in more pronounced negative effects on strength-endurance exercise but not in maximal strength. Cycling results in more negative effects on strength endurance performance exercise than running. A 4-hour to 8-hour recovery interval seems to be enough to avoid interference on strength-endurance performance. Reduction in strength-endurance performance is located in muscle groups involved in both exercises. Low aerobic exercise volume (3 km) with; 18 minutes of duration does not diminish strength endurance, whereas higher volumes (5 and 7 km) with ;30 and ;42 minutes of duration, respectively, generate impairments. Caffeine, carbohydrate, and beta-alanine are not able to revert the deleterious effect on strength-endurance performance, whereas creatine and capsaicin analog supplementation are. Thus, these variables must be taken into consideration to prescribe and organize a CT session. This information may help coaches to organize exercise sessions that minimize or avoid the impairment in strength performance after aerobic exercises.
