This infographic presents data of the speeds and distances that experienced National Hockey League (NHL) players traveled over the course of 11 seasons.

This Kinetic Select from NSCA’s Essentials of Personal Training, Second Edition gives a brief overview of respiratory adaptations, and how aerobic interventions of duration and intensity can be used for specific adaptations for endurance training.

This excerpt will briefly discuss the importance of exercise, dosage of the supplement, efficacy, body mass changes, and adverse effects of creatine.

The physiological response to breath holding includes bradycardia and peripheral vasoconstriction, which contrasts with that of exercise which includes tachycardia and peripheral vasodilation. This raises the question as to what the physiological response is to breath holding during exercise. During low-intensity exercise, the breath holding response of bradycardia and peripheral vasoconstriction prevails over the exercise response of tachycardia and peripheral vasodilation, but nevertheless the exercise may be sustained. Due to the lack of availability of extrinsic oxygen (O 2 ) from the atmosphere during breath holding, the energy demands can be met by increased reliance on intrinsic O 2 stores (i.e., O 2 that was in the body before the breath hold) via increased O 2 extraction at the muscle compared with exercise while breathing, or increased contributions from anaerobic energy systems. During high intensity exercise of short duration, the exercise response may prevail over the breath holding response due to the increased parasympathetic withdrawal and sympathetic drive of higher intensity exercise. If breath holding during high-intensity exercise was sustained for long enough, the breath holding response may eventually overcome the exercise response, although this may be difficult due to the inverse relationship between exercise intensity and breath hold duration.

The loading intensity a person chooses depends on his or her goals and training status (i.e., whether the person is a trained athlete or a sedentary individual). Ultimately, the number of repetitions you can perform at a given intensity or load determines the effects of training on strength develop.

Coaches can use drills to improve quickness and agility. The training session can improve the specific areas needed to increase performance results by setting up appropriate intensity levels, duration of drills, recovery periods, and volume of drills.

This excerpt from the Essentials of Strength Training and Conditioning outlines what training typically looks like in the preparatory period, or off-season.

This infographic breaks down the demands that forwards and defensemen face in official National Hockey League (NHL) games.

Learn how to increase the body’s use of fat as a fuel without compromising the use of carbohydrates for higher-intensity training. Mike Nelson, PhD, explains how combining specific nutrition and exercise together affects the use of fat as a fuel, in this session from the NSCA’s 2017 Personal Trainers Conference.

There is growing evidence that polarized endurance training is a promising method for optimizing a tactical athlete’s cardiovascular system, preparing for physical performance tests, allowing for a more full recovery during deployment, and allowing for safer return to duty after injury or deployment.
