Effects of Core Instability on Muscle Activity
January 15, 2019by Developing the Core
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.

Oxygen Uptake and the Aerobic and Anaerobic Contributions to Exercise
June 8, 2018by Essentials of Strength Training and Conditioning- 4th Edition.
Oxygen uptake (or consumption) is a measure of a person’s ability to take in oxygen and deliver it to the working tissues, and the ability of working tissues to use oxygen. During low-intensity exercise with a constant power output, oxygen uptake increases for the first few minutes until a steady state of uptake is reached.

Catecholamines
June 14, 2018by Essentials of Strength and Conditioning 4th Edition With Web Resource
The catecholamines—primarily epinephrine, but also norepinephrine and dopamine—are secreted by the adrenal medulla and are important for the acute expression of strength and power because the hormones act as central motor stimulators and peripheral vascular dilators to enhance enzyme systems and calcium release in muscle.

Aerobic Endurance Measures and Analyses
June 8, 2018by Developing Endurance
The VO2max test is the most effective measurement of the body’s ability to deliver and use oxygen for producing energy that can be used by the muscles. VO2max (i.e., maximum aerobic power) simply stands for the maximal volume of oxygen that can be used.
