Impact of 14 days of head‐down bed rest and an exercise countermeasure on skeletal muscle atrophy, proteome and circulatory cytokines in older adults

open access: yesExperimental Physiology, EarlyView.
Abstract Prolonged bed rest and immobilization have deleterious effects on skeletal muscle mass and function, especially in older adults. These can lead to reduced physical capacity and quality of life. Previous experiments in younger individuals show that exercise can mitigate these effects, but evidence remains scarce and inconclusive in older adults.

Passive heat therapy is feasible but does not affect cardiometabolic health outcomes in persons with spinal cord injury – a pilot study

open access: yesExperimental Physiology, EarlyView.
Abstract Passive heat therapy can improve cardiometabolic health outcomes in some clinical populations, making it a potential therapeutic tool for individuals with spinal cord injury (SCI), who exhibit elevated cardiometabolic disease risk and face barriers to physical activity.

Jumping in simulated lunar gravity with blood flow restriction as a potential exercise countermeasure: The acute physiological effects

open access: yesExperimental Physiology, EarlyView.
Abstract The present study examined the cardiovascular, metabolic, neuromuscular and perceptual effects of low‐intensity jumping in simulated lunar gravity (∼20% bodyweight) with blood flow restriction (BFR). Fourteen healthy adults (24 ± 4 years; 1.81 ± 0.06 m; 75 ± 12 kg) completed an incremental jumping test in simulated lunar gravity (9.5° head‐up ...

A comparison of the neuromuscular, cardiopulmonary and muscle oxygenation responses to single‐ and double‐leg cycling in older adults

open access: yesExperimental Physiology, EarlyView.
Abstract Previous work in younger adults has shown that during small muscle mass exercise, the tolerable degree of neuromuscular impairment at task failure is greater than during large muscle mass exercise. However, no study has compared the neuromuscular responses to small and large muscle mass exercise whilst matching exercise modality in older ...

(Poly)phenols: Mechanisms of action and efficacy of contemporary supplements for exercise recovery and performance

open access: yesExperimental Physiology, EarlyView.
Abstract (Poly)phenols are a diverse group of bioactive chemical compounds present in a wide range of plant‐ and animal‐based foods. Several thousands of (poly)phenols exist; many have potent biological effects, most notably antioxidant, anti‐inflammatory and vasodilatory.

Phosphate and acidosis cause fibre‐typespecific changes to cellular and molecular contractile mechanics at 37°C in skeletal muscle from older adults

open access: yesExperimental Physiology, EarlyView.
Abstract Intracellular accumulation of hydrogen ions (H+) and inorganic phosphate (Pi) has temperature‐dependent effects on single‐fibre contractile function between 10°C and 30°C. In vivo, human skeletal muscle temperatures range between 35‐39°C, and although contractile function is highly dependent on temperature, the effects of fatigue‐inducing [H+]

Senolytics and exercise: Dual modalities for rejuvenating muscle

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend The role of senolytics on the heart and skeletal muscle. Senescent cell burden increases with ageing, disuse and disease. The senolytics dasatinib+quercetin (D+Q), navitoclax and fisetin, as well as exercise, eliminate senescent cells, reducing senescent cell burden and their senescence‐associated secretory phenotype (SASP ...

LOWER CORRELATION BETWEEN BICEPS FEMORIS CONTRACTION TIME AND MAXIMAL RUNNING SPEED IN CHILDREN THAN IN ADULTS: A LONGITUDINAL STUDY IN 9- TO 14-YEAR OLD CHILDREN

open access: yesAnnales Kinesiologiae, 2016
Biceps femoris is a major propulsor muscle in sprinting and its contraction time negatively correlates to the running speeds of adults. Our aim was to compare age and gender- related correlations between vastus lateralis and biceps femoris contraction ...
