This article explores the possible advantages of staying active during pregnancy and how it can positively impact health and well-being.

The purpose of this article is to discuss the gray area that should be considered when it comes to implementing weightlifting exercises.

This article discusses how high-intensity interval training may be an effective metabolic training method for soldiers trying to maintain physical preparedness during deployment.

The purpose of this article is to give an overview and theoretical framework on the concept of periodized nutrition—with an emphasis on adequate carbohydrate intake to enhance performance.

The variables of an NBA season constantly change, which requires strength and conditioning coaches to adjust accordingly. The success of a program is often influenced by the coach’s ability to combine strength and conditioning principles with common sense and the ability to adjust to the schedule.

This article aims to discuss concurrent activation potentiation (CAP) and the proposed mechanisms underlying it, summarize the available research examining the phenomenon, and provide strategies for its implementation.

The physiological response to breath holding includes bradycardia and peripheral vasoconstriction, which contrasts with that of exercise which includes tachycardia and peripheral vasodilation. This raises the question as to what the physiological response is to breath holding during exercise. During low-intensity exercise, the breath holding response of bradycardia and peripheral vasoconstriction prevails over the exercise response of tachycardia and peripheral vasodilation, but nevertheless the exercise may be sustained. Due to the lack of availability of extrinsic oxygen (O 2 ) from the atmosphere during breath holding, the energy demands can be met by increased reliance on intrinsic O 2 stores (i.e., O 2 that was in the body before the breath hold) via increased O 2 extraction at the muscle compared with exercise while breathing, or increased contributions from anaerobic energy systems. During high intensity exercise of short duration, the exercise response may prevail over the breath holding response due to the increased parasympathetic withdrawal and sympathetic drive of higher intensity exercise. If breath holding during high-intensity exercise was sustained for long enough, the breath holding response may eventually overcome the exercise response, although this may be difficult due to the inverse relationship between exercise intensity and breath hold duration.

The goal of this article is to understand contralateral and ipsilateral loading, how to set-up loaded carries, electromyography activity during exercises, and how to apply these exercises into the strength training program.
