Experimental data were recorded from seven participants for a broad range of steady-state locomotion speeds (walking at 1.59±0.09 m s(-1) to sprinting at 8.95±0.70 m s(-1)). is not the same as a chemical equilibrium. A 1981 edition of Webster's dictionary provides a rather Correspondence. Vasu_Patel8. They are also used to troubleshoot quality problems. For a steady-state, there is a net reaction, so some amounts change (the amount of source and sink), while at least one species – the one at steady state – has a constant concentration as long as the conditions of steady state prevail. This time was chosen as a balance between the likelihood of achieving steady-state physiology without causing fatigue. Maintenence of a constant internal environment during unstressed conditions.
