Haematological adaptations to high‐altitude and heat acclimation training in elite male cyclists

Experimental Physiology, EarlyView.
Abstract High‐altitude training is widely adopted by endurance athletes with the aim of increasing total haemoglobin mass (tHbmass) and thereby endurance exercise performance. However, divergent effects on tHbmass and exercise performance have been reported in athletes commencing altitude camps with initial high baseline levels for tHbmass, questioning

Maximal strength and voluntary activation of adductor pollicis after a single session of acute intermittent hypercapnia or acute intermittent hypoxia

Experimental Physiology, EarlyView.
Abstract Acute intermittent hypoxia (AIH) can increase maximal strength of limb muscles in people with incomplete spinal cord injury (SCI), but it is mostly untested in people without SCI. Acute intermittent hypercapnia (AIC) may engage similar respiratory circuits to AIH, but the effects of AIC on human limb motor output are unknown.

Determinants of maximal oxygen uptake in highly trained females and males: a mechanistic study of sex differences using advanced invasive methods

The Journal of Physiology, EarlyView.
Abstract figure legend The results from this study show that maximal cardiac output, stroke volume and leg blood flow are similar between highly trained females and males after normalisation to lean body mass (LBM). However, the 10% higher haemoglobin concentration ([Hb]) and arterial O2 content in males result in higher systemic and leg O2 delivery ...

Frequency Analysis of a Superconducting Magnetic Bearing System in Ring Spinning Using an Eddy Current Damper

PAMM, Volume 26, Issue 1, March 2026.
ABSTRACT The conventional ring‐spinning process has been used for over a century, being one of the most used processes in the textile industry. However, this process has some disadvantages at high spindle speeds, such as friction in the traveler/ring components that generates heat, resulting in yarn breakages or lower‐quality production.

Friction Shock Absorbers and Reverse Thrust for Fast Multirotor Landing on High‐Speed Vehicles

Journal of Field Robotics, Volume 43, Issue 2, Page 1068-1090, March 2026.
ABSTRACT Typical landing gears of small uninhabited aerial vehicles (UAV) limit their capability to land on vehicles moving at more than 20–50 km/h due to high drag forces, high pitch angles and potentially high relative horizontal velocities. To enable landing at higher speeds, a combination of lightweight friction shock absorbers and reverse thrust ...
