This article will demonstrate why personal trainers should consider the use of blood flow restriction (BFR) and BFR technology for appropriate medically-screened clients that provides an objective way to apply pressure, whether that is through manual or automated cuffs.

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.

The purpose of this article is to discuss the theory behind the French Contrast Method (FCM), current evidence demonstrating its effectiveness, as well as proper implementation and execution for athletic populations.

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.

This infographic displays the meta-analysis details of 36 studies and the effects of postactivation potentiation with heavy loads on vertical jump performance.

The purpose of this article is to discuss the gray area that should be considered when it comes to implementing weightlifting exercises.

This article is the sixth 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.

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.

This article reviews electromyography (EMG) procedures as well as provides examples of how EMG data analysis has been used in tactical populations.

In this video from the NSCA's 2013 Personal Trainer Conference, Chad Waterbury discusses how to maximize motor unit recruitment. Chad discusses three ways to recruit more motor units - lift heavy, accelerate sub-maximal loads, and train with high-tension movements.
