Effects of seat height on muscular pattern and interlimb coordination in cycling
Journal Title: Journal of Science and Cycling - Year 2016, Vol 5, Issue 2
Abstract
The riding position is a key factor for performance in cycling particularly to prevent chronic diseases related to practice. Even though some authors use the crotch length to get the ideal seat height, others base the riding position on knee kinematics [1]. Whereas seat height modifications affect the timing and the kinematic variables, a certain empiricism seems to prevail with the consequence of frequent muscle and joint chronic diseases [2]. Moreover, if the interjoint coordination may be affected by the position [3], the pattern of muscle activation may also be affected, resulting in an imbalance between the anterior and posterior muscle chains [4]. Although osteoarticular structures are directly affected, the neuromuscular system is affected leading to a modification of kinematic, muscular pattern coordination and motor response. Moreover, beyond lower limb kinematics, intergirdle coordination could be crucial to determine a position adapted to the person. The aim of the present study is to establish how interjoint and muscular pattern coordination are affected by various height of seat and whether it affects intergirdle coordination.

Spectral properties of muscle activation during incremental cycling test
It is uncertain whether fatigue and workload would affect muscle recruitment during cycling. To infer on changes in priority for recruitment of motor units, we assessed the combined effects of fatigue and workload during...
Do 3-min all-out test parameters accurately predict competitive cyclist performance in the severe intensity domain?
Background: It is well established that the critical power (CP) and the fixed amount of work performed above the CP (W’) predict performance in the severe intensity domain, and that this two parameters can be successfull...

Validity of Track Aero System to assess aerodynamic drag in professional cyclists
Purpose: Aerodynamic drag is the main resistance (80-90 %) among the total resistive forces (RT, N) opposing motion on level ground in cycling. It is important to decrease it to improve the performance in time-trial (TT)...
