When a stress intensity range ΔK is applied to a material for some number of cycles ΔN, this drives the crack to grow in length by a specific amount Δa. The growth rate of the crack at a specific stress intensity range is then given by the ratio Δa/ΔN. In continuous form, the crack growth rate is given by the derivative da/dN .

High intensity laser radiation is a relatively new method of application in physical therapy practice, ... react to it by mechanotransductive mechanism and interaction between the tissue and the laser radiation alters the mechanics of the microenvironment of the cell, thereby acting on the cells by mechanical stress.

Running – Run at a high speed for 30 seconds, then jog/run at a low speed for 30-90 seconds. Repeat 10 times, or until you hit 20 minutes. Resistance Training – Perform a circuit workout of three exercises (Push-Ups, Pull-Ups, and Squats) with no rest between each exercise, then once you've finished all three, take a 60-second rest.

In the four-part series on CrossFit's charter of mechanics, consistency, and intensity, we defined terms and discussed the training application in the broadest sense. In this article, we will mine the same concepts for a more specific training application. Trainers often struggle with how to take concepts like "mechanics, consistency, and intensity" …

A 2-wk HIIT intervention provides significant improvements in cardiac autonomic modulation and myocardial function and mechanics in a large cohort of young physically inactive and highly sedentary individuals, demonstrating that HIIT may be an important stimulus to reduce the health implications associated with physical inactivity …

The purpose of this study was to determine the effect of impaired quadriceps function on knee joint biomechanics and neuromuscular function during gait. Surface electromyograms, three-dimensional motion and ground reaction forces were collected during gait before and after 20 healthy adults completed a high intensity quadriceps fatigue protocol.
