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.

This article will review the latest evidence regarding optimal rest intervals, and the science behind them.

While pharmaceutical treatment is complex, dynamic, and important for optimal glycemic control, exercise clearly plays a critical, but often overlooked, role in the overall treatment plan for patients with T2D or those at risk of developing it.

This article highlights the benefits of exercise for adolescents with attention-deficit/hyperactivity disorder (ADHD). It also provides practical recommendations for high school strength and conditioning coaches working with ADHD student-athletes.

There are five ways that a strength and conditioning position is typically structured in a high school. Each position structure has its own pros and cons that should be evaluated for your specific situation.

Falls resulting from trips are a leading cause of injury and can sometimes result in death, especially in the older population. Numerous researchers have studied the biomechanical mechanisms that differentiate fallers from nonfallers and determined whether training can beneficially impact those outcomes. Exercise and task-specific interventions have demonstrated fewer falls after trips but can be costly and often require specialized equipment, making their applicability less practical. Qualified health and fitness practitioners can develop evidence-informed, exercise-based programs focusing on 3 components (balance training, task-specific training, and resistance exercise). Such programs may help to reduce fall risk in older adults based on previously documented studies identifying the biomechanical demands of a successful fall arrest after a trip perturbation. These multicomponent programs should include a safe task-specific training element that does not require specialized equipment.

Nutrition and dietary intake are key factors for exercise and sport performance. While a substantial body of research highlights the impact of nutrition on exercise, many dietary and nutrient recommendations are based on research studies only conducted in men. However, the distinct physiological, neurological, and hormonal changes across a woman’s life cycle significantly affect nutritional needs. This narrative review explores key recommendations for calories, carbohydrates, fats, proteins, and select supplements, highlighting the absence of sex-specific guidelines in current dietary frameworks for strength and conditioning female athletes. The review synthesizes current literature to provide practical guidance for coaches, sport dietitians, and health practitioners to optimize both performance and health outcomes for female athletes.
