Consumption of dietary protein by athletes is a common intervention to maximize gains in muscle and strength, and to improve body composition. The purpose of this article is to analyze the current research on the optimal amount of dietary protein for resistance training athletes.
This article summarizes the relevant literature regarding post-workout nutrient timing and its importance to training adaptations, specifically increasing skeletal muscle hypertrophy and replenishing skeletal muscle glycogen stores.
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.
This column will explore specific investigations that evaluate the impact of PA and fitness on mental and physical health outcomes among firefighters and law enforcement officers.
Learn how diet and strength training in the absence of aerobic exercise can be used to improve body composition through simultaneous fat loss and muscle gain. In this session from the NSCA’s 2016 Personal Trainers Conference, Todd Miller demonstrates how to use body composition and metabolism measurements along with popular food tracking apps and activity monitors to design individualized diet and exercise strategies. CEUs available.
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.
The goal of this article is to define some of the basic physiological responses to acute and chronic altitude exposure and to provide some evidence-based, practical guidelines when approaching training and racing at higher altitudes.
