OBJECTIVES The aim of this study was to determine whether exercises can change the cervical angle and respiratory function in smartphone users. METHODS Thirty healthy volunteers were recruited. The subjects were randomly divided into an exercise group and a control group. All participants used a smartphone for 1 hour while maintaining a sitting posture. Then, each group performed their assign...

The effects of carbon monoxide on exercise tolerance as assessed by the distance walked in 12 minutes were studied in 15 patients with severe chronic bronchitis and emphysema (mean forced expiratory volume in one second 0.56 1, mean forced vital capacity 1.54 1). Each subject walked breathing air and oxygen before and after exposure to sufficient carbon monoxide to raise their venous carboxyhae...

[Purpose] The aim of this study was to examine whether a systematic high intensity aerobic exercise on treadmill was effective in improving pulmonary function. [Subjects and Methods] The subjects of this study were 22 healthy elderly women over 65 years of age who were attending the Senior Welfare Center and Social Welfare Center programs in B city. For the pulmonary function test, a spirometry...

The endurance time during constant high work-rate exercise (t(LIM)) is used to assess exercise capacity in patients with chronic obstructive pulmonary disease and as an outcome measure for pulmonary rehabilitation. Our study was designed to establish the minimum clinically important difference for the t(LIM). t(LIM) was measured in 105 patients (86 males) before and after an 8-week outpatient p...

Both clinical and animal studies suggest that exercise may be an effective way to manage inflammatory and neuropathic pain conditions. However, existing animal studies commonly use forced exercise paradigms that incorporate varying degrees of stress, which itself can elicit analgesia, and thus may complicate the interpretation of the effects of exercise on pain. We investigated the analgesic po...

Maternal deprivation during the first 10 days of life induces significant behavioral alterations in rodents which persist through adulthood. Physical exercise reduces the cognitive deficits associated with pharmacologic and pathological conditions. Here we investigated whether forced physical exercise alters memory deficits caused by postnatal maternal deprivation. Male rats were divided into f...

In eight patients with exercise-induced asthma, disodium cromoglycate was found to produce a definite inhibition of the post-exercise fall in forced expiratory volume in one second. This effect may be part of the cause for the subjective improvement experienced with this drug.

CLINICAL PRESENTATION A 34-year-old woman with atopic asthma since the age of 16 years presented with increasing exertional dyspnoea and wheeze over a period of 12 months. She had no symptomatic benefit from escalation of bronchodilator therapy and her peak expiratory flow (PEF) remained reduced despite multiple courses of oral corticosteroid. Lung function at rest showed mild air flow obstruct...
