Exercise echocardiography for improved assessment of diastolic filling dynamics
Experimental Physiology, EarlyView.Abstract During exercise stress, heart rate (HR) increases to support cardiac output, which also reduces ventricular filling time. Although echocardiography is widely used to assess cardiac function, studies display conflicting data on the dynamic changes in the healthy trained and untrained heart during rest and acute exercise stress. To address these

The evolution of muscle spindles
Experimental Physiology, EarlyView.Abstract Muscle spindles are stretch‐sensitive mechanoreceptors found in the skeletal muscles of most four‐limbed vertebrates. They are unique amongst sensory receptors in the ability to regulate their sensitivity by contraction of the intrafusal muscle fibres on which the sensory endings lie.

Experimental Physiology, EarlyView.Abstract We review our approach for undertaking microelectrode recordings from the posterior tibial nerve at the ankle, which has allowed us to identify, for the first time, the firing properties of muscle spindle endings in the intrinsic muscles of the foot and of cutaneous mechanoreceptors in the sole during unsupported standing.

Optogenetic methods to stimulate gamma motor neuron axons ex vivo
Experimental Physiology, EarlyView.Abstract It is challenging to stimulate gamma motor neurons, which are important regulators of muscle spindle afferent function, without also recruiting alpha motor neurons. Here, we test the feasibility of stimulating gamma motor neuron axons using optogenetics in two transgenic mouse lines. We used an ex vivo muscle–nerve preparation in adult mice to

Repetition‐dependent acute cardiopulmonary responses during intensity‐matched squats in males
Experimental Physiology, EarlyView.Abstract The ‘strength–endurance continuum’ is a key concept in strength training (ST). Although cardiopulmonary responses have seldom been reported in conjunction with ST, this repeated‐measurement study examined acute blood pressure and haemodynamic responses continuously depending on the number of repetitions but without changing the intensity ...
