Although research has largely focused on the effects of physical activity (PA) on the brain, less is known about the influence of the brain on engagement in healthy-living behaviors, such as regular PA. In this secondary analysis of a study...

Increased intrapulmonary shunt (QS/Qt) and alveolar dead space (VD/VT) are present in early recovery from 2019 Novel Coronavirus (COVID-19). We hypothesized patients recovering from severe critical acute illness (NIH category 3-5) would hav...
Maternal cardiorespiratory coupling: differences between pregnant and nonpregnant women are further amplified by sleep-stage stratification [0.03%]
母体心呼吸耦合：按睡眠阶段划分后孕产妇和非孕产妇的差异进一步扩大

Pregnancy complications are associated with abnormal maternal autonomic regulation. Subsequently, thoroughly understanding maternal autonomic regulation during healthy pregnancy may enable the earlier detection of complications, in turn all...
Muscle blood flow and vasodilation are blunted at the onset of exercise following an acute bout of ischemia-reperfusion [0.03%]
一过性缺血再灌注后运动早期肌肉血流和血管扩张反应减弱

Brady E Hanson et al.
Ischemia-reperfusion (I/R) injury can attenuate endothelial function and impair nitric oxide bioavailability. We tested the hypothesis that I/R also blunts the rapid and steady-state hyperemic and vasodilatory responses to handgrip exercise...

We applied the recently introduced concept of intramuscle synergies in spaces of motor units (MUs) to quantify indexes of such synergies in the tibialis anterior during ankle dorsiflexion force production tasks and their changes with fatigu...
Assumptions about the cross-sectional shape of skinned muscle fibers can distort the relationship between muscle force and cross-sectional area [0.03%]
肌纤维横截面形状的假设可能会扭曲肌肉力与横截面积之间的关系

Comparisons of muscle force output are often performed after normalization to muscle physiological cross-sectional area (CSA). Differences in force per CSA (i.e., specific force) suggest the presence of physiological differences in contract...
Sex-related differences in profiles of muscle oxygen saturation of different muscles in trained cyclists during graded cycling exercise [0.03%]
训练有素的自行车运动员在分级骑行运动中不同肌肉氧气饱和度性别差异性研究

Although in recent years near-infrared spectroscopy has been used in many sports to monitor muscle oxygen saturation (SmO2), there is a lack of knowledge about the sex differences in SmO2 during exercise in different muscles. Our study aime...
Acute upper and lower limb hemodynamic responses during single sessions of low- versus high-intensity inspiratory muscle strength training [0.03%]
单次低强度和高强度吸气肌力量训练的上、下肢血液动力学急性反应的对比研究

Inspiratory muscle strength training (IMST) has shown potential to improve both respiratory and cardiovascular function in health and disease. Less is known about acute hemodynamic responses to a single IMST session, therefore we assessed u...
The effects of inorganic nitrate supplementation on exercise economy and endurance capacity across the menstrual cycle [0.03%]
