This article is the eleventh in a continuing series of tactical strength and conditioning (TSAC) research reviews. It is designed to bring awareness to new research findings of relevance to tactical strength and conditioning communities.

This excerpt from Developing Agility and Quickness explains the agility considerations for different wrestling disciplines.

All stressors affect training, Dr. Bryan Mann says in this lecture from Coaches Conference 2015. No matter the source of the stress - strength training, conditioning, classes, relationship or family - stress is systemic within the body. As a result, it is critical to monitor the stress load on your athletes to ensure maximal results, and it's easy to do - all you need is a pencil and paper.

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.

With the need to be ready under any circumstances from operational missions to physical training, understanding how the adrenal gland functions is important for any tactical athlete. The adrenal gland mediates performance and can have a negative effect on the body’s physiology when exhausted. It is vital to understand the interventions needed to obviate the negative effects and enhance the positive aspects of such physiological function. This session from the 2015 TSAC Annual Training sheds light on this important physiological system that impacts both physical health and functional performance.

The effects of alcohol on athletic performance vary depending on quantity, demographics, and type of exercise, making it difficult to determine specific recommendations. From an athletic performance standpoint, the acute use of alcohol can influence motor skills, hydration status, aerobic performance, as well as aspects of the recovery process.

This article discusses using the principle of specificity as an important component in tactical training programs to enhance performance, decrease injuries, and improve functional longevity of a tactical athlete.
