Effects of Plyometric Training on Sports Performance

May 1, 2017

Article

Plyometric training is a series of explosive bodyweight resistance exercises using the stretch-shortening cycle of the muscle fiber to enhance physical capacities, such as speed, strength, and power. These physiological measures translate to improved performance in many sports, including court-based sports, field sports, and water sports.

Measurement of Power

June 1, 2017

Article

It is important for coaches to understand the relationship between commonly measured variables (e.g., displacement, velocity, and force) and their relationship to the derived variable of power.

Multi-Joint Training versus Isolated Training for Core Development

June 1, 2017

Article

Ground-based free weight lifts, especially the explosive Olympic-style lifts, are highly recommended for athletic conditioning for the core muscles. They can provide a moderately unstable stimulus to augment activation of the core and limb muscles, while still providing maximal or near maximal strength, velocity, and power output.

SCJ 47.1 A Discussion of the Combined Effect of Resistance Training and Time-Restricted Eating on Body Composition and Neuromuscular Adaptations

Quiz CATD 0.2

Time-restricted eating (TRE) is an application of intermittent fasting where an individual consumes their calories in a specific eating window (e.g., 8 hours) followed by a prolonged fasting window (e.g., 16 hours). Several randomized controlled trials have analyzed the combined effect of resistance training (RT) and TRE on physical adaptations, including fat mass (FM) loss, fat-free mass (FFM) retention, hypertrophy, local muscular endurance, power, and strength. In this mini review, we highlight the methodology and results from these studies and conclude by providing practical application suggestions for fitness professionals striving to maximize RT + TRE with their clientele. Generally, RT + TRE leads to positive body composition changes, including FM loss and FFM retention, which culminates in improved body fat percentage. Similarly, RT + TRE consistently stimulates positive neuromuscular adaptations, such as increased hypertrophy, local muscular endurance, power, and strength. When positive changes are not observed, and when safely implemented, RT + TRE rarely confers negative effects on the abovementioned adaptations. In short, RT + TRE may be a beneficial dietary and exercise strategy to improve body composition and muscular fitness. However, there are several caveats for practitioners to consider, which are discussed at length in this article.
