Translational perspectives on neurophysiological responses and mechanisms in blood flow restriction exercise

Experimental Physiology, EarlyView.
Abstract Maintaining corticospinal tract function is crucial for voluntary movement. Exercise using high external loads/intensities is a promising intervention to promote adaptations to the corticospinal tract and improve physical function; however, such loads/intensities may not be tolerable or safe in populations with neurological disorders, motor ...

The acute and chronic effects of local aerobic exercise on cardiovascular physiology

Experimental Physiology, EarlyView.
Abstract Exercise training has beneficial effects for primary and secondary prevention of cardiovascular disease (CVD). Effects of exercise training have typically been studied in the form of whole‐body exercise training, partly driven by the assumption that larger effects of exercise training can be achieved by involving more and larger muscle groups.

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

Experimental 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 ...

A heat pump-driven mechanical vapor compression desalination system and its operating characteristics

Water Resources and Industry
The converter valve of ultra-high-voltage direct current grid requires a large amount of cooling water for heat dissipation. Considering the generated waste heat, this study proposes a heat pump-driven mechanical vapor compression (HP-MVC) desalination ...

Muscle cramp susceptibility is associated with muscle‐specific modulation of human motoneuron discharge patterns

Experimental Physiology, EarlyView.
Abstract Muscle cramps are painful, involuntary contractions thought to arise from altered spinal motoneuron excitability, potentially involving persistent inward currents (PICs). We examined whether cramp susceptibility is associated with altered PIC‐related motoneuron behaviour and whether electrically induced cramp modifies these estimates.

Antioxidant supplementation blunts the proteome response to 3 weeks of sprint interval training preferentially in human type 2 muscle fibres

The Journal of Physiology, EarlyView.
Abstract figure legend Sprint interval training (SIT) is a popular time‐efficient type of endurance training. Healthy young men performed nine SIT sessions (4–6 × 30 s all‐out cycling sprints) over 3 weeks while being supplemented with antioxidants (high doses of vitamins C and E) or placebo. Muscle biopsies taken before and after the first SIT session

Neuromuscular fatigability with repeated exercise in hypoxia: From single‐joint paradigms to sprints

The Journal of Physiology, EarlyView.
Abstract figure legend Acute hypobaric or normobaric hypoxic exposure accelerates neuromuscular fatigability during repeated exercise. Indices of peripheral and central fatigue are not different at exhaustion in mild, moderate and severe hypoxia compared with normoxia, but task failure occurs earlier.

Resistance training load does not determine resistance training‐induced hypertrophy across upper and lower limbs in healthy young males

The Journal of Physiology, EarlyView.
Abstract figure legend In healthy young males, we found that skeletal muscle hypertrophy following a period of resistance exercise training (RET) was consistent within and between subjects, as assessed using a variety of established methods. The skeletal muscle hypertrophic response was independent of external load.

Physiological mechanisms underlying enhanced performance with blood flow restriction training: neuromuscular, vascular and metabolic adaptations

The Journal of Physiology, EarlyView.
Abstract figure legend We investigated how 6 weeks of dynamic knee‐extensor interval training with blood flow restriction (BFR‐leg) and without (CTRL‐leg) impacts performance and its mechanisms using non‐invasive methods. Specifically, we used gold‐standard methods to assess neuromuscular function, vascular function using Doppler ultrasound, and near ...
