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.

Although it may be possible to increase skeletal muscle levels of carnitine by combining it with relatively large amounts of carbohydrates repeatedly throughout the day, or by taking it with choline, there is limited data that shows that carnitine is a fat-burner that results in significant reductions in fat mass.

This article provides methods used by tactical facilitators, related research articles, and professional interviews to demonstrate how physical conditioning facilitates the transition from practice to duty for service members, including law enforcement and fire and rescue personnel.

As Director of Sport Science at the University of Nevada, Las Vegas (UNLV), Heather Farmer spearheads comprehensive integration efforts. This includes ensuring every stakeholder, from sport performance staff to academic advisors, has a seat at the table. Farmer also outlines developing an internship and graduate assistantship program to meet staffing needs and offer opportunities for practical experience. She recounts how leveraging relationships — not data — has been her key to scalability. Additionally, Farmer recognizes that to make an impact, she must meet athletes and sport coaches where they are, which she uncovers through “highlights” and “hurdles.” She suggests that sport scientists with strength and conditioning backgrounds, like herself, are uniquely equipped to excel due to their communication skills. Farmer and McMahon also discuss avoiding “analysis paralysis” and how to incorporate data to elevate the student-athlete experience — an unignorable factor as athletes bring an element of “self” in the age of name, image and likeness (NIL).

For many athletes, being agile is the end goal of physical performance training. It represents their capacity to change velocity and direction in response to the actions of their opponent and the opportunities and constraints of their environment. The aim of this article was to describe the pitch-based development of agility, focusing on 60–1808 turns. This ensures all turns have the demand of deceleration, turning, and reacceleration, requiring both outside leg turns (608) and inside leg turns (1808). To enable the effective coaching of these, coaches must understand movement mechanics and thus the fundamental principles that underpin good technique. Within agility training, a detailed appreciation of how the center of mass and base of support interact to affect the direction of force is fundamental to this. This understanding and the ensuing technical models ensure athletes have the best chance of executing the task optimally and ensure coaches can effectively instruct athletes and adapt drills accordingly.

Parkinson disease (PD) is a progressive and chronic neurodegenerative disorder that compromises both motor and nonmotor functions, ultimately leading to a decline in functional capacity and quality of life. Although the etiology of PD is multifaceted, exercise has shown promising effects in managing PD symptoms and enhancing patient well-being. Although aerobic and resistance exercise demonstrate benefits within this specific population, the exact application of these modalities varies and often differs depending on disease progression and the individual. Although individuals diagnosed with PD are encouraged to exercise, there is still a lack of information pertaining to how to successfully structure physical activity into their daily routine. There are also distinct barriers and motivators impacting their decision to engage in regular exercise. This manuscript offers practical recommendations and personalized exercise guidelines for exercise professionals, empowering them to optimize PD management through targeted exercise interventions. In addition, it offers current information on promoting exercise among patients with PD, specifically to enhance their functional outcomes.

Colorado Springs, CO – The National Strength and Conditioning Association Foundation is proud to announce the recipients of the foundation’s 2018 grants. Since the Foundation’s creation in 2007, it has awarded 136 grants, which includes the 16 new recipients this year.

For Keith Swift, coaching is completely effort based, but it starts with camaraderie and education. As Director of Strength and Conditioning at Wofford College, his philosophy is clear: educate, heal, and enhance. While playing collegiate football and studying exercise science, Swift learned early to question the “why” behind training and encourages his student-athletes to do the same. At an academically rigorous institution, his educational focus fits right in, fostering curiosity, technical precision, and peer coaching. Swift shares how his experiences across professional baseball, the private sector, and collegiate programs each shaped his foundation while making it his own. Amid collegiate challenges — from the National Collegiate Athletic Association (NCAA) transfer portal to the growing authority of student-athletes — Swift holds firm that “there is no substitute for hard work.” His goal is simple: help student-athletes leave with both a degree and a championship ring, setting them up for success in sport and life.
