On the other days, I do yoga, weight training, or bicycle anything to cut down on the repetitive force that running places on my knees.
This is true for every loading occurrence, be it impulse, vibration, short-term quasi-static, or long-term protracted or repetitive force exposure.
Importantly, repetitive forces with broadly distributed frequencies elicited very similar molecular responses compared to fixed-frequency forces.
The flNcd-driven transport was not degraded by the microsphere attachment or the repetitive force-velocity scans, as microtubule sliding velocities before and after microsphere attachment and conducting force-velocity scans did not differ significantly (N = 26 microtubules, Kolmogorov Smirnov test: p = 0.14, Supplementary Figure 4).
Peroneal Tenosynovitis The peroneal tendons are subjected to excessive repetitive forces causing pain, swelling and instability of the lateral ankle.
Stretch-activated ion channels might be part of the transduction pathway of repetitive forces [ 32, 33].
Thus, such lesions are the result of the repetitive forces of weight-bearing in patients whose gait is unmodified by sensory feedback (15).
The repetitive forces create mechanical environment in the regenerated tissue, being affected by the location (the depth) and the stiffness of the gel plug that located beneath the tissue.
Moreover, the action of manual propulsion necessitates that the hand exerts repetitive forces to the handrim [ 6, 7] in order that the hand/handrim coupling be stable to accommodate the transfer of the forces from the shoulder and arm muscles onto the handrim [ 7].
It's a repetitive task that requires enough force and work at strange angles to cause thumb and wrist injuries and other ergonomic problems in the people who used to do it.
