Natural experiments are a form of passive experiments that analyse populations exposed to environmental or behavioural stimuli. Here, we review natural experiments using marathon running as an example of an unusual physiological stressor to...
The impact of acute sleep fragmentation on muscle blood flow responses to handgrip exercise [0.03%]
急性睡眠片段化对肌力练习时肌肉血流反应的影响

Sleep fragmentation is reported to impair resting vascular function. The aim of this study was to test the hypothesis that acute sleep fragmentation would impair muscle blood flow during exercise. Twenty adults (10 females, 10 males) partic...
Cardiovascular and cognitive consequences of steep head-down tilt in awake older men [0.03%]

Janus Adler Hyldebrandt et al.
This study investigated cerebral hemodynamics, intracranial pressure, and cognitive function in eighteen older men (median 72 years, IQR 68-75, 94% with ≥1 comorbidity) during a 15-minute 30-degree head-down tilt (HDT). Participants were m...
Endurance Training Attenuates Acute Exercise-Induced Monocyte Transcriptomic Responses in Adolescents: Sex-Specific Molecular Adaptations [0.03%]
耐力训练减弱青少年单核细胞急性运动反应的转录组变化：性别特异性分子适应性响应

Abel Plaza-Florido et al.
Background: Circulating monocytes contribute to atherogenesis and vascular dysfunction. Although clinical cardiovascular disease presents in adulthood, its biological origins often begin in youth and differ substantially between females and...
Effect of Albuterol on Compliance and Distensibility of the Trachea and Lungs [0.03%]
倍他乐克对气管和肺顺应性和顺应性的的影响

Chamindu C Gunatilaka et al.
Tracheomalacia (TM), the most common abnormality of the pediatric trachea, results in dynamic expiratory airway collapse due to weakened cartilage and reduced smooth muscle tone. Although bronchodilators such as albuterol are widely used in...
Beyond hypothermia: mechanisms of death, rescue, and prevention in cold water immersion - a narrative review [0.03%]
溺水低温下的死亡、救援和预防机制-综述文章
Laura Leuci,Jørgen Melau,Antonio Messina et al.
Laura Leuci et al.
Cold water immersion (CWI) is a significant cause of open-water drowning mortality. Epidemiological data challenge the prevailing assumption that hypothermia is the primary mechanism of death, pointing instead to acute responses that preced...
Association between neural-drive variability and motor function in middle-aged and older adults [0.03%]
中老年人神经驱动波动与运动功能之间的关系
Roger M Enoka,Jacques Duchateau
Roger M Enoka
The purpose of this review was to examine the extent to which variability in the cumulative set of action potentials sent from the spinal cord (neural drive) to limb muscles can explain the variance in performance of middle-aged and older a...
Effects of age on intramuscular fascicle kinematics of the medial gastrocnemius muscle of track and field Masters athletes [0.03%]
年龄对田径大师运动员腓肠肌内侧头肌肉内肌纤维运动学的影响
Sarah Michely,Uwe Mittag,Edwin Mulder et al.
Sarah Michely et al.
Aging results in a decline in muscle mass and intrinsic mechanical properties, yet its impact on intramuscular force transmission and fascicle kinematics remains poorly understood. We investigated whether age, sex, and habitual high-intensi...
Sex Hormones and Menopause Hormone Therapy Predict Muscle Strength Across the Lifespan [0.03%]
lifespan中激素与绝经期激素治疗对肌肉力量的影响
Rachel N Logue Cook,Adina F Turcu,Carrie A Karvonen-Gutierrez et al.
Rachel N Logue Cook et al.
Aging is associated with declines in muscle strength, yet after menopause the relative rate of decline is greater in females than males. Whether sex hormones are predictive of strength across the lifespan and with aging is largely unknown. ...
