This article highlights the scientific evidence on exercises like the seated leg extension, leg curl, and adduction machines to highlight their potential benefits on enhanced performance and potentially reducing injury risk.

Acceleration is the rate of change in velocity, so this phase of sprinting is critical for changing directions as rapidly and efficiently as possible. Optimal technique for linear sprinting in the acceleration phase involves four factors that maximize stride length and frequency.

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 excerpt from NSCA’s Essentials of Personal Training discusses the importance of education on proper running surfaces, appropriate footwear, and the benefits of cross-training in addressing overuse of the knee.

This article provides an overview of the scientific evidence comparing specific motor control exercise intervention to using a more general exercise approach, and concludes by discussing the practical implications for strength and conditioning professionals from an exercise programming perspective.

Considering that the term "power" typically evokes the perception of high-speed movement, many people are inclined to take the tenets of specificity to literally mean “train fast, be fast.” However, to create the most strategic methods of training and adaptation, it is vital to compartmentalize power into the primary testable and trainable elements.
