Several techniques are available to assess muscle tissue status, including electrical impedance myography (EIM). Despite being used in the assessment of neuromuscular status injury and response exercise, reliability data for hamstrings muscles limited. Therefore, this study aimed determine test-retest EIM components on hamstrings. Twenty-one healthy males (25.3 ± 3.4 years; 173 6.7 cm; 79.7 15....

Technological advancements in past decades have led to the development of integrative analytical approaches to lipidomics, such as liquid chromatography-mass spectrometry (LC/MS), and information about biogenic lipids is rapidly accumulating. Although several cohort-based studies have been conducted on the composition of urinary lipidome, the data on urinary lipids cross-classified by sex, age,...

OBJECTIVE We tested the hypothesis that the reductions of the changes in the respective influence of the cardiac sympathetic and vagal activity control and delta EEG activity with aging alter the interactions between the heart rate variability (HRV) and the delta sleep EEG power band. METHODS A polysomnography was performed on 16 healthy young men and 19 healthy middle-aged men across the fir...

Methods and Results-—Thirteen healthy young (23 2 years) and 13 older men (61 5 years) were instructed to continuously wear a compression sleeve around the right forearm to chronically (2 weeks) elevate brachial artery retrograde SR in 1 arm. We assessed SR, diameter, and flow-mediated dilation in both the sleeve and contralateral control arms at baseline and after 30 minutes and 2 weeks of con...
