OBJECTIVES: The effectiveness of supervised exercise programs (SEPs) for the management of peripheral arterial disease (PAD) can be hampered by low accessibility and poor compliance. The current international availability and use of SEPs was evaluated and the evidence on alternative approaches such as structured, home-based exercise programs (HEPs) was reviewed. ...

Human tidal breathing features mathematical complexity and breath-by-breath variability. Fluctuations in these descriptors from one state to another are related to the load imposed on the respiratory system. We hypothetized that bronchodilators would increase ventilatory complexity and variability in patients suffering from chronic obstructive pulmonary disease (COPD). Eleven patients with ...

Recurrent laryngeal neuropathy (RLN) is the most common cause of laryngeal hemiplegia in horses and causes neurogenic atrophy of the intrinsic laryngeal muscles, including the cricoarytenoideus lateralis muscle. Recurrent laryngeal neuropathy results in paresis to paralysis of the vocal fold and arytenoid cartilage, which limits performance through respiratory compromise. Ultrasound ...

Interoceptive sensitivity is an essential component of recent models of "the self." Increased focus on the self (e.g., self-observation in a mirror) can enhance aspects of self-processing. We examined whether self-observation also enhances interoceptive sensitivity. Participants performed a heartbeat detection task while looking at their own face in a mirror ...

Rehabilitative techniques for dysphagia (swallowing impairment) increasingly employ exercise modeled on methods used to train muscles in sports medicine. Three techniques in particular show promise for improving muscle strength and function related to swallowing: the Shaker exercise, expiratory muscle strength training, and tongue pressure resistance training. All three techniques invoke ...

Exercises can suffer from a lack of realism that reduces the value of the exercise in terms of the positive experience of the participant and the possibility that outcomes are based on artificialities created by the exercise environment. It is important to minimise these so that participants actively engage and ...

The beneficial effects of regular physical exercise on cardiovascular morbidity and mortality are well documented. In rare cases, however, athletes with cardiovascular abnormalities are at increased risk of exercise-related sudden cardiac death (SCD). Paradoxically, most SCDs can be attributed to cardiovascular abnormalities that can be identified during an athlete's life. ...
