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.

A review of the literature concludes that a strength training program including low-intensity to high-intensity resistance exercises and plyometric exercises performed 2 – 3 times per week for 8 – 12 weeks is an appropriate strategy to improve running economy in highly trained middle- and long-distance runners.

By reviewing this simplified process of obtaining a client’s health history and physician release, designing an exercise routine with modified exercises, and providing exercises for paid clients versus general members, NSCA-CPTs can be confident prescribing a routine for those who suffer from chronic or temporary health issues.

Almost all functional movements of the trunk are combinations or variations of four basic movement patterns: trunk flexion, trunk extension, trunk rotation, and trunk lateral flexion. This article lists exercises to address each of these movement patterns.

Coach Joe Kenn, MA, CSCS,*D, RSCC spoke at the NSCA's 2012 National Conference about how to choose the correct exercises and develop a comprehensive daily plan.

In this hands-on lecture from the NSCA's 2014 TSAC Conference, Lee Burton talks about the need to remedy mobility dysfunction in tactical athletes, and discusses the Functional Movement System and programming functional exercise progressions.

Parkinson disease (PD) is a progressive and chronic neurodegenerative disorder that compromises both motor and nonmotor functions, ultimately leading to a decline in functional capacity and quality of life. Although the etiology of PD is multifaceted, exercise has shown promising effects in managing PD symptoms and enhancing patient well-being. Although aerobic and resistance exercise demonstrate benefits within this specific population, the exact application of these modalities varies and often differs depending on disease progression and the individual. Although individuals diagnosed with PD are encouraged to exercise, there is still a lack of information pertaining to how to successfully structure physical activity into their daily routine. There are also distinct barriers and motivators impacting their decision to engage in regular exercise. This manuscript offers practical recommendations and personalized exercise guidelines for exercise professionals, empowering them to optimize PD management through targeted exercise interventions. In addition, it offers current information on promoting exercise among patients with PD, specifically to enhance their functional outcomes.
