The first in a two part series, this infographic explains how to create a null hypothesis and interpret p values in research.

The purpose of this article is to provide personal trainers reading the strength and conditioning research the knowledge necessary to better understand the statistical data commonly reported in research manuscripts.

One resistance training variable that may be altered to achieve desired outcomes is the range of motion used in training. Generally, the strength and conditioning field has accepted that using a greater range of motion in strength training exercises results in more substantial muscle hypertrophy outcomes. However, this theory has proved to be inconsistently supported in the literature, and to date, no sufficient explanation exists to explain this phenomenon. This review article seeks to outline a novel approach for potentially describing the disparities seen in range of motion research with respect to hypertrophy outcomes by applying the unique length-tension curve of each muscle being examined. As will be discussed in the review, virtually all the results from range of motion studies in various muscles have corresponded to each muscle’s length-tension curve; muscles that are active on the descending limb of the curve appear to garner greater hypertrophy from using larger ranges of motion. Conversely, muscles that are not active on the descending limb exhibit similar adaptations despite alterations in range of motion. A novel hypothesis for applying this information to resistance training programs will be presented and discussed.

This is the second part of a two-part series that investigates the effects of dietary carbohydrate availability on exercise performance and how specifically timed restriction of carbohydrates may also paradoxically enhance exercise performance in the medium and long term.

Evidence suggests a positive relationship between physical activity, exercise, and mental health. Exercise as a treatment modality is now being considered alongside psychotherapeutic and pharmacological approaches, and the role of specifically trained exercise specialists and personal trainers is an important component of the multi-disciplinary team.

During the rehabilitation process, a client may need therapy outside of the personal trainer’s scope of practice. This article discusses safe and effective modalities that personal trainers can use with clients in the post-rehabilitation phase process.

The snatch is one of the most technically demanding competitive movements. This article focuses on barbell trajectory (or bar path), motor control, and the height of the bar relative to the athlete’s body.

This article explores the process and reasoning behind integrating an athletic trainer within a fire department to provide clinical care and injury prevention protocols.

This article provides the personal trainer with sample exercise progressions for teaching resistance training movement patterns along with practical strategies for instruction and reinforcement of proper technique.
