UNLABELLED Soccer induces neuromuscular fatigue requiring several hours of recovery. PURPOSE The study aimed to determine the extent to which neuromuscular fatigue occurs in high-level professional players and its recovery after a match and to examine its relationship with central and peripheral fatigue indicators. METHODS Maximal voluntary contraction(More)
Exercise-induced muscle damage (EIMD) is known to decrease muscle strength and power but its effect on endurance performance is unclear. Thirty moderately trained adult runners (24 men and six women) were randomly assigned to EIMD or control. The EIMD group jumped 100 times from a 35 cm bench, while controls did not perform any muscle-damaging exercise.(More)
Locomotor muscle fatigue, defined as an exercise-induced reduction in maximal voluntary force, occurs during prolonged exercise, but its effects on cardiorespiratory responses and exercise performance are unknown. In this investigation, a significant reduction in locomotor muscle force (-18%, P < 0.05) was isolated from the metabolic stress usually(More)
OBJECTIVE In approaching the study and practice of heart failure (HF) management, authors recognise that the patient-doctor relationship has a central role in engaging patients in their care. This study aims at identifying the features and the levers of HF patient engagement and suggestions for orienting clinical encounters. DESIGN Using a grounded theory(More)
T-cell receptor excision circles (TRECs) and kappa-deleting recombination excision circles (KRECs) are circular DNA segments generated in T and B cells during their maturation in the thymus and bone marrow. These circularized DNA elements persist in the cells, are unable to replicate, and are diluted as a result of cell division, thus are considered markers(More)
BACKGROUND Peripheral fatigue in knee extensor (KE) and plantar flexor (PF) muscles were investigated following repeated-sprint ability (RSA) cycling and running tests. METHODS Both RSA tests involved 5x6 s sprints and peripheral fatigue was quantified using diverse electrical stimulations (1Hz, 10Hz, 20Hz, 50Hz and 100Hz). RESULTS RSA cycling induced(More)
The purpose of this study was to evaluate the metabolic cost of running (Cr) on natural grass (NG) and artificial turf (AT), compared with a hard surface (HS), that is, asphalted track. Eight amateur soccer players (mean ± SD: age 22.9 ± 2.3 years, body mass 69.0 ± 4.7 kg, and height 178 ± 5 cm) completed 9 runs (3 surfaces × 3 speeds, i.e., 2.22, 2.78,(More)
"Small sided games," used effectively in many team sports as a form of training, can be mimicked in combat sports by fighting at different subjective intensities, based on adjectives proposed by coaches. This approach could aim at improving aerobic performance by using specific techniques. Nevertheless, an adequate perception of intensity is crucial. The(More)
This study assessed how accurately professional swimmers can interpret instructions to swim "slow," "moderate," and "fast." 8 distance swimmers (6 males, 2 females; M age = 19 yr., SD = 3) and 8 sprint swimmers (7 males, 1 female; M age = 18 yr., SD = 1) performed an all-out 50-m crawl stroke and three sets of 8 × 50-m crawl stroke trials interpreting the(More)
