Growth hormone release is affected by the type of resistance training protocol used, including the duration of rest periods. Short rest period types of workouts result in greater serum concentrations compared to long rest protocols of similar total work; however, at present it is not clear how the various molecular forms or types of growth hormones are affected by rest period duration.
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.
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.
Triathlons are unique compared to other sports as athletes are required to master three distinct disciplines: swimming, cycling, and running. This article lays out a training program that focuses on a balance between strength training and sport training to avoid overtraining and overuse injuries and to maximize performance in a multi-sport athlete.
This article provides an overview of the scientific evidence comparing specific motor control exercise intervention to using a more general exercise approach, and concludes by discussing the practical implications for strength and conditioning professionals from an exercise programming perspective.
