Sleep Loss Impairs Inspiratory Muscle Endurance

American Review of Respiratory Disease, 1989
Sleep loss is common in patients with respiratory disorders. To determine whether sleep loss affects respiratory muscle function, we compared respiratory muscle and pulmonary functions after normal sleep with those measured after a 30-h sleepless period in 30 normal male subjects.

Muscle Damage and Endurance Events

Sports Medicine, 1986
Intensive training for and competition in endurance events like the marathon are accompanied by injury to fibres in the active skeletal muscles. Evidence for the injury comes from the increases in intramuscular enzymes and myoglobin found in the blood following the exercise, from the subjective sensation of soreness in the muscles in the post-exercise ...

Respiratory Muscle Endurance in Obesity Hypoventilation Syndrome

Respiratory Care, 2022
An increase in respiratory work load and resistance to respiration cause a decrease in respiratory muscle endurance (RME) in patients with obesity hypoventilation syndrome (OHS). We aimed to evaluate and compare RME in subjects with OHS and a control group using an incremental load test and compare the RME of subjects with OHS in whom noninvasive ...

Endurance properties of respiratory and limb muscles

Respiration Physiology, 1983
Endurance properties of the inspiratory and expiratory muscles were compared with those of the flexors and extensors of the elbow in healthy volunteers. During a series of sustained contractions separated by rest intervals of one minute there was a progressive decline in the force produced by both muscle groups acting at the elbow and by the expiratory

Heredity and muscle adaptation to endurance training

Medicine & Science in Sports & Exercise, 1986
To determine whether sensitivity of muscle characteristics and aerobic performances to endurance training was genotype-dependent, 6 pairs of monozygotic (MZ) twins, 21 +/- 4 yr of age (mean +/- SD), took part in a 15-wk ergocycle endurance training program. Tests were performed before and after 7 and 15 weeks of training.

Strength and Local Muscle Endurance

Physical Medicine and Rehabilitation Clinics of North America, 1994
Muscle performance can be improved in several ways, including increasing the load, number of contractions, velocity of contraction, and improved technique. The single, most important variable, however, is the tension developed in the muscle during training. Because there is only limited transfer of static training to dynamic performance, pure isometric

Changes in respiratory muscle endurance during puberty

Pediatric Pulmonology, 2005
The evaluation of respiratory muscle endurance provides clinically useful information on muscle function, especially in children with respiratory and neuromuscular diseases. However, endurance may be lower in young children than in older children because of the major physical changes of puberty.

Endurance training increases skeletal muscle lactate transport

Acta Physiologica Scandinavica, 1993
Lactate accumulation in skeletal muscle is reduced after a period of endurance training. Explanations for this phenomena include the increased oxidative capacity of the muscle, a reduction in lactate production, and increased lactate clearance.

Biochemical Adaptations to Endurance Exercise in Muscle

Annual Review of Physiology, 1976
Two quite distinct adaptive responses can be induced in skeletal muscle by regularly performed, strenuous exercise. The nature of the exercise stimulus determines the type of adaptation. One type of adaptation involves hypertrophy of the muscle cells with an increase in strength; it is exemplified in its most extreme form by the muscles of weight ...

Study of Endurance of Various Muscle Groups

Research Quarterly. American Association for Health, Physical Education and Recreation, 1964
Abstract Endurance of three muscle groups was studied ergometrically: flexors of the forearm in 30 subjects, flexors of the hand, and extensors of the lower leg in 20 subjects. The flexors of the forearm were tested with two ergometers: the lever and the pulley type.
