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.
Evidence suggests a positive relationship between physical activity, exercise, and mental health. Exercise as a treatment modality is now being considered alongside psychotherapeutic and pharmacological approaches, and the role of specifically trained exercise specialists and personal trainers is an important component of the multi-disciplinary team.

Lifestyle modification, including exercise, is important for both preventing and treating hypertension. More recent guidelines for treating hypertension have increased emphasis on lifestyle factors, such as exercise. As fitness professionals, it is important to educate and encourage clients with hypertension on the importance of exercise in their overall health.

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.
Exercise is an underutilized therapy for the treatment of cognitive diseases such as Alzheimer’s disease and depression. While exercise shows more promise for the prevention, rather than the treatment, of Alzheimer’s disease, exercise therapy compares favorably to the most common treatments of depression (psychotherapy and antidepressants).

Oxygen uptake (or consumption) is a measure of a person’s ability to take in oxygen and deliver it to the working tissues, and the ability of working tissues to use oxygen. During low-intensity exercise with a constant power output, oxygen uptake increases for the first few minutes until a steady state of uptake is reached.
In this lecture from the NSCA's 2014 Coaches Conference, Mike Robertson talks about corrective exercise and its application. Invoking Gray Cook, Mike defines corrective exercise as "a holistic approach where an assessment is used to determine specific weaknesses and/or limitations of the athlete" - be it aerobic, strength, or agility.
This article will demonstrate why personal trainers should consider the use of blood flow restriction (BFR) and BFR technology for appropriate medically-screened clients that provides an objective way to apply pressure, whether that is through manual or automated cuffs.
