Concurrent training with long-interval HIIT does not impair skeletal muscle protein synthesis or hypertrophy: Little evidence of an 'interference effect' [0.03%]
高强度间歇训练不会影响骨骼肌蛋白质合成或肥大：几乎没有“干扰效应”的证据
Miguel Conceição,Felipe C Vechin,Guilherme Telles et al.
Miguel Conceição et al.
Concurrent training is commonly associated with blunted muscle hypertrophy compared to resistance training alone, but the underlying physiological mechanisms remain unclear. This study aimed to investigate the acute and chronic effects of c...
Functional Electrical Stimulation of the Soleus Redistributes Lower-Limb Joint Work Distally in Young and Older Adults [0.03%]
足底屈肌功能性电刺激可使年轻人和老年人的下肢远端关节工作量发生重新分布
Ningzhen Zhao,Ross H Miller,Lisa Griffin et al.
Ningzhen Zhao et al.
Older adults walk with reduced ankle and greater hip mechanical output compared to young adults. This "distal-to-proximal redistribution" likely contributes to the greater metabolic energy expenditure during walking in older versus young ad...
Motor unit discharge properties of the vastii muscles and their modulation with contraction level depend on the knee-joint angle [0.03%]
股二头肌 motor 单位发放性质及其在不同收缩水平下的调节受膝关节角度影响
Tamara Valenčič,Sumiaki Maeo,Stefan Kluzek et al.
Tamara Valenčič et al.
This study examined the effect of the knee-joint angle on motor unit (MU) discharge properties of the vastii muscles and their modulation with contraction level. Twelve young adults performed unilateral isometric knee-extension contractions...
Carbohydrate ingestion during prolonged exercise and net skeletal muscle glycogen utilization: A meta-analysis [0.03%]
运动中糖原利用的meta分析：运动中摄入碳水化合物的影响
Jeffrey A Rothschild,Harrison Dudley-Rode,Harriet Carpenter et al.
Jeffrey A Rothschild et al.
Background: While some studies report attenuated net muscle glycogenolysis with carbohydrate ingestion, others show no effect, possibly due to small sample sizes or methodological differences. Objective: To determine whether carbohydrate in...
Five days of physical inactivity induced by dry immersion alter skeletal muscle metabolism and whole-body glucose tolerance in healthy men [0.03%]
5天失重性肌肉无力影响健康男性骨骼肌代谢和全身葡萄糖耐量
Benjamin Lair,Elisa Le Roux,Isabelle de Glisezinski et al.
Benjamin Lair et al.
Even brief periods of physical inactivity can induce metabolic disruptions; however, the underlying cellular and molecular mechanisms initiating these alterations remain unclear. We investigated whole-body and skeletal muscle-specific metab...
Modulation and recovery kinetics of soleus responses to peripheral nerve and transcutaneous spinal cord stimulation under different interventions [0.03%]
不同干预下腓肠肌周围神经和脊髓刺激反应的调制及恢复速率
Julia Sordet,Alain Martin,Ioannis G Amiridis et al.
Julia Sordet et al.
Transspinal evoked potentials (TEPs) elicited by transcutaneous spinal cord stimulation (tSCS) share some neurophysiological similarities with the H-reflex evoked by peripheral nerve stimulation (PNS). The purpose of this study was to furth...
Big Bones Mean Big Muscles: An MRI-Based Dataset of Muscle-Bone-Body Size Relationships Across 70 Human Muscles of the Upper Limb, Trunk, and Lower Limb [0.03%]
大骨骼意味着大肌肉：基于MRI的跨大小肢体、躯干和下肢的70个人体肌肉-骨骼-体型关系数据集
Lara Riem,Megan Pinette,Olivia DuCharme et al.
Lara Riem et al.
Body sizes and shapes vary widely, even among healthy adults, resulting in diverse muscle sizes, strengths, and performance capacities. This study developed an AI (artificially intelligent) algorithm to segment individual muscles and bones ...
Sex differences in English Channel swimming performance: An experiment of nature [0.03%]
英吉利海峡游泳竞技的性别差异：一次自然实验
Lucas A Lacambra,Jonathon W Senefeld,Michael J Joyner et al.
Lucas A Lacambra et al.
Sex differences in endurance performance are well established, but the magnitude of these differences appears smaller in ultra-endurance events, particularly swimming. This study examined sex differences in solo English Channel swimming per...
Ultramarathon racing elicits changes in behavioural and electroencephalographic indices of executive function [0.03%]
超马拉松比赛会引起执行功能的行为指标和脑电图指标的变化
Katherine Boere,Nevan P Young,Frances Copithorne et al.
Katherine Boere et al.
The purpose of this study was to determine whether racing a 50-km ultramarathon alters behavioural and electrophysiological (EEG) indices of executive function. Seventy-six recreational runners (37 ± 10 y; 39 F, 37 M) completed EEG assessm...
Motor Variability as an Index of Fatigue in Dynamic Actions: a Perspective from the Optimal Movement Variability Theory [0.03%]
基于最优运动变异性理论的动态行为中疲劳的标志：运动变异性的视角
Fernando García Aguilar,Miguel Lopez-Fernandez,David Barbado et al.
Fernando García Aguilar et al.
Background: Fatigue is a complex process that affects both force production and movement execution. Traditional measures, such as countermovement jump (CMJ) height, assess performance decrements but fail to capture compensatory movement ada...
