Assessing respiratory mechanics and muscle function is critical for both clinical practice and
research purposes. Several methodological developments over the past two decades have …

Objectives Two distinct types of specific respiratory muscle training (RMT), ie respiratory
muscle strength (resistive/threshold) and endurance (hyperpnoea) training, have been …

Inspiratory muscle training may have beneficial effects in certain patients with chronic
obstructive pulmonary disease (COPD). Because of the lack of a home training device, …

Background Although physical exercise is recommended for asthmatics, evidence on the
effects of exercise on clinical key factors is still missing. Objectives We performed a systematic …

Background Current recommendations advise against exercising in the evening because of
potential adverse effects on sleep. Objectives The aim of this systematic review was to …

1 Many physiological and behavioural functions have circadian rhythms – endogenous
oscillations with a period of approximately 24 h that can occur even in the absence of sleep. We …

For many years, it was believed that ventilation does not limit performance in healthy
humans. Recently, however, it has been shown that inspiratory muscles can become fatigued …

Numerous studies have demonstrated a diurnal rhythm in indices of pulmonary function in
both healthy subjects and subjects with asthma, with minima occurring during the night. To …

The objective measurement of fatigue is of critical relevance in areas such as occupational
health and safety as fatigue impairs cognitive and motor performance, thus reducing …

We tested whether the increased cycling endurance observed after respiratory muscle training
(RMT) in healthy sedentary humans was associated with a training-induced increase in …
