Eight weeks of post‐exercise local heating does not improve cognition and plasma brain‐derived neurotrophic factor concentrations

open access: yesExperimental Physiology, EarlyView.
Abstract Exercise and heat stress have been reported to independently provide benefits to brain health. We tested the hypothesis that 8 weeks of post‐exercise local heating, passive local heating only, or exercise training only improves cognitive performance compared to a control group.

Charge Symmetry Breaking in the Valence Quark Distributions of the Nucleon

open access: yes, 1996
Using a quark model, we study the effect of charge symmetry breaking on the valence quark distributions of the nucleon. The effect due to quark mass differences and the Coulomb interaction of the electrically charged quarks is calculated and, in contrast

Sex differences in the prefrontal cortex and muscle oxygenation during exercise until exhaustion in endurance‐trained individuals

open access: yesExperimental Physiology, EarlyView.
Abstract figure legend During cardiopulmonary exercise testing, the decline in oxygenation in the prefrontal cortex of women is striking. This crucial brain area is directly involved in planning motor tasks. The decline is particularly pronounced at higher exercise intensities, especially after reaching the respiratory compensation point or anaerobic ...

Bridging the chiral symmetry and confinement with singularity

open access: yesPhysics Letters B, 2020
We consider a holographic quark model where the confinement is a consequence of the quark condensate. Surprisingly, the equation of motion of our holographic model can be mapped to the old spin-less bag model.

Identification of the individual cardiac contraction threshold during high‐frame‐rate stress echocardiography

open access: yesExperimental Physiology, EarlyView.
Abstract The clinical assessment of cardiovascular function during exercise using stress echocardiography is essential for accurate cardiac diagnosis. However, normal limitations of cardiac deformation responses to increasing physical exertion remain poorly understood.

Baryon form factors in a diquark-quark bound state description

open access: yes, 1995
Nucleon form factors are calculated in a relativistic diquark--quark picture based on the Nambu--Jona-Lasinio model. The nucleon wave function is obtained in a static approximation to the quark exchange interaction between the valence quark and the ...

Weak magnetism in chiral quark models [PDF]

open access: yes, 2000
We discuss symmetry breaking in the weak magnetism form factors for the semileptonic octet baryon decays. In the chiral quark model, the symmetry breaking can be accounted for in the masses and the quark spin polarizations can take on more general values

The maturation of regional sweating patterns from childhood to young adulthood in females

open access: yesExperimental Physiology, EarlyView.
Abstract Children are considered heat vulnerable, with the belief that maturation of sweating occurs throughout childhood. Indeed, young children demonstrate distinct patterns of regional sweating compared to adults, but little is known about this pattern maturation throughout puberty. This study aimed to investigate the maturation of regional sweating
