Abstract: PurposeHistorically, the efficiency of leg cycling has been difficult to change. However, arm cycling research indicates that relative crank angle changes can improve efficiency. Therefore, we investigated if leg cycling with different relative crank angles… read more here.

DOI: 10.1007/s12206-016-1209-z
Abstract: Clearances in the joints of mechanisms are unavoidable because of numerous uncertainties, such as manufacturing tolerances, assembly processes, and progressing wear. The dynamic characteristics of a planar slider-crank mechanism, including clearance joint and balancing mechanism,… read more here.

Abstract: Abstract Transmission angle control is well studied for both crank rocker and Grashof crank slider mechanisms. However, non-Grashof slider-crank mechanisms have received less attention. For these mechanisms, the fully rotatable crank constraint is removed increasing… read more here.

DOI: 10.1080/02701367.2021.2009109
Abstract: Purpose: In modern sprint cycling competitions, the athletes perform a preparatory movement that consists in reaching the backmost standing position, quickly accelerating the body forward at the starting signal. The purpose of this study was… read more here.

DOI: 10.1111/anae.14312
Abstract: Arm‐crank ergometry may be useful in patients unable to pedal, for instance due to peripheral arterial disease. Twenty participants with small abdominal aortic aneurysm undertook two serial arm‐crank tests and then a pedal test, four… read more here.
