Pre‐season friendly match‐play as a double‐edged sword: Performance gains and inflammatory cost in semi‐professional soccer players (a natural experiment)

Experimental Physiology, EarlyView.
Abstract Pre‐season training prepares soccer players for competition, but the longitudinal effects of friendly match exposure remain unclear. We investigated whether cumulative late pre‐season match‐play is associated with physiological adaptation in semi‐professional players.

Impact of living and training at low altitude for several years on endurance performance at higher altitude: Myth or reality

Experimental Physiology, EarlyView.
Abstract The physiological adaptations of long‐term high‐altitude residents without high‐altitude genetic ancestry remain poorly characterized. This study investigated whether permanent residence at low altitude (1200 m) influences performance at higher altitude (2500 m). We compared exercise responses at 2500 m in endurance‐trained athletes living for

Age‐related loss of hysteresis in the spontaneous vascular sympathetic baroreflex is associated with altered neural rather than mechanical control

Experimental Physiology, EarlyView.
Abstract The vascular sympathetic baroreflex is critical for stabilising blood pressure. A notable feature of this reflex is hysteresis, a directional asymmetry in responsiveness during rising versus falling pressure that is evident in young adults but attenuated in older age.

Intense unimanual contractions increase muscle excitation and local metabolic activity in the resting contralateral forearm

Experimental Physiology, EarlyView.
Abstract Intense unilateral muscle contractions evoke measurable activity within the contralateral neuroaxis, which can be detected with surface electromyographic activity in the resting homologous muscle. Physiological mirror activity (PMA), the unintentional increase in contralateral muscle excitation, has been implicated in cross‐limb interactions ...

Comparing the Predictive Power of Subjective and Objective Health Indicators: Changes in Hand Grip Strength and Overall Satisfaction with Life as Predictors of Mortality [PDF]

Self-reported measures of health are generally treated as weak measures of respondents' objective health status. On the other hand, most surveys use self-reported health to measure health status and to determine the effects of a range of other socio ...

The ‘lactate paradox’ revisited after 35 years: In memoriam Paolo Cerretelli

Experimental Physiology, EarlyView.
Abstract Some decades ago significant scientific interest was raised by the concept of the ‘lactate paradox’ occurring during altitude acclimatization. In short, in acute hypoxia blood lactate− concentration ([La]b) is higher, compared to normoxia, at any given submaximal work rate, whereas peak [La]b at exhausting exercise is unchanged.

Pulmonary arterial mechanoreceptors modulate exercise‐induced sympathetic activation in healthy humans during moderate‐intensity hypoxic exercise

The Journal of Physiology, EarlyView.
Abstract figure legend This randomized cross‐over trial (N = 12) addressed the hypothesis that selective reduction of pulmonary arterial pressure (i.e. manipulation of pulmonary arterial mechanoreceptor activation) during hypoxic exercise would reduce sympathetic outflow (muscle sympathetic nerve activity (MSNA)) in healthy humans.

Arterial–venous differences of brain‐derived neurotrophic factor isoforms across the brain and muscle after exercise at different intensities

The Journal of Physiology, EarlyView.
Abstract figure legend Exercise‐induced increases in forearm venous plasma and serum brain‐derived neurotrophic factor (BDNF) are often assumed to be indicative of release from the brain. Sixteen healthy and physically fit adults (20–40 years old) were recruited to investigate whether exercise‐induced changes in forearm venous mature BDNF (mBDNF) and ...
