Ankle sprains are an extremely common injury of both sports and everyday life. In the post-rehabilitation setting, it is important to first identify and then address deficits in ankle, hip, and knee range of motion and strength.

In the push for personal training sales, many gyms will use assessment protocols as a way to prove to clients that they can indeed benefit from personal training. This article examines the merits behind this concept.

This article provides a proposed holistic solution to increase functional, quality movement among Marines, thereby increasing physical performance, reducing injuries, and developing more effective warfighters.

The Certified Performance and Sport Scientist (CPSS) is a practitioner with training and applied experiences across the scientific disciplines applicable to sport science and athletic performance (i.e., generalist) or predominantly within a select few (i.e., specialist). These scientific disciplines, as related to sports performance, include, but are not limited to: biomechanics, data science, nutrition, physiology, psychology, research methods, and strength and conditioning. A CPSS demonstrates competency in the application of scientific disciplines, assessment, training theory and process, needs analysis, monitoring, communication, and education with the primary goal of safely and effectively improving athletic performance.

Blood pressure changes acutely during resistance exercise. Continuous, beat-by-beat assessment provides detailed temporal resolution of blood pressure profiles, through techniques including intra-arterial catheterization, photoplethysmography, or applanation tonometry. However, noncontinuous measurements may be conducted before and after resistance exercise through auscultatory sphygmomanometry or oscillometry. Blood pressures tend to increase across repetitions within sets, influenced by load magnitude, repetitions and sets performed, muscle mass recruited, and rest periods; the highest pressures result from multi-joint, large muscle group exercises. Evaluation of such factors may facilitate better understanding of blood pressure responses to acute resistance exercise and influence program design considerations relative to anticipated hemodynamic changes.

Maximal force can be expressed across a range of conditions influenced by the external load and the time available to express force. As a result, several distinct and specific strength qualities exist. Conversely, some expressions of maximal force are similar and can be categorized as a single quality. Therefore, strength assessment systems must be sophisticated enough to isolate and measure each quality while minimizing redundant information. This article presents a contemporary, evidence-based and practical framework that reduces the many strength and speed-strength metrics into 5 distinct qualities. Alongside this, we present case examples of the application of strength diagnosis.

As the second of a three part series, this article will focus on the Practitioner Pillars of LTAD, including relevant monitoring and assessment tools, as well as systematical progressions and individualized training programs for successful long-term physical development.

In this lecture from the NSCA's 2014 TSAC Conference, Katie Sell talks about the unique demands and skills required of wildland firefighters. Because wildland firefighters are involved in many different disciplines, Katie stresses the importance of fitness for not only job performance, but survival.

Body composition is an important physical characteristic to consider for football players and their performance. Tyler Bosch goes over the various methods of measuring body composition, what the numbers really mean, and how they can be used to develop a player's training.

Assessing clients is a vital component of the personal training experience. This article gives an overview of breathing mechanics and how to apply proper breathing exercises into a client’s assessment and program.
