Resistance training (RT) is a nonpharmacological complement to cancer treatments due to its effectiveness in attenuating sarcopenia, cardiotoxicity, fatigue, and emotional disorders common in oncology patients. To adequately program and evaluate the acute or long-term effects of this type of training, a proper evaluation of the patients’ strength levels is necessary. Strength evaluations traditionally applied to this population required reaching muscle or technical failure, which could increase their discomfort levels, risk of injury, or other complications associated with the disease. In this regard, this manuscript described different dynamic and isometric evaluations recommended to accurately and safely evaluate the strength of the oncology population. Concerning dynamic evaluations, the velocity based method is recommended to determine the capacity of the patient to apply force against maximal (i.e., 1 repetition maximum) and submaximal loads. The sit-to-stand or vertical jump tests are also proposed as alternatives to evaluate dynamic strength using body weight. For isometric assessments, the knee extension and handgrip tests could complement dynamic evaluations or replace them for patients with very low strength levels. Besides describing in depth the aforementioned evaluations, the current review proposes important methodological aspects to ensure their accurate, reliable, and safe implementation.

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.

Contracted Human Performance and Optimization Coach of 2nd Ranger Battalion, 75th Ranger Regimen Jeff Carroll talks to the NSCA Head Strength and Conditioning Coach, Scott Caulfield, about his start in the field of strength and conditioning and his transition from professional athletes to a tactical population and setting. Topics under discussion include: Carroll’s career path, coaching professional athletes, transitioning to tactical strength and conditioning, and the future of tactical strength and conditioning.

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.
