This article discusses the effects of instability on force and velocity throughout the body.

Potentially, an instability training program that first involves static balance and then progresses to dynamic balance activities would improve intrinsic balance. This improvement in balance would increase movement confidence, releasing the neuromuscular system from a stiffening strategy to more unimpeded motion, force, and power development.

This article briefly examines the most popular instability training devices and provides examples of how instability training can be incorporated into traditional resistance training programs.

Lateral ankle sprains are one of the most common injuries sustained during sport or physical activity. Up to 40% of individuals can develop chronic lateral ankle instability (CLAI) after a lateral ankle sprain. CLAI occurs when functional or mechanical insufficiencies of the lateral ankle ligamentous complex persist. The purpose of this article is to identify characteristics of CLAI and describe strength and conditioning strategies that can be used to treat lateral ankle ligamentous injuries, preventing them from progressing on to CLAI.

This TSAC Report article examines the primary risk factors contributing to shoulder pain in tactical athletes and provides evidence-based rehabilitation strategies. Visit NSCA online to learn more about exercise research for tactical athletes.

This Kinetic Select from Developing the Core reviews the effects of muscle activity when performing exercises on unstable surfaces.

The career path of a personal trainer inherently presents a certain amount of instability and unpredictability, but this does not have to last. There is no reason that personal trainers cannot make great money, afford health insurance, save for retirement, and create more freedom in their lives.

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.

Nearly all fitness professionals are forced to address low back pain (LBP) to some extent, regardless of the age or population with which they work. The purpose of this article is to shed light on contemporary research surrounding LBP.
