Fourteen male subjects performed two-legged hopping at 2.2Hz before and after a 3-min passive stretching of the triceps surae (dorsiflexion of 30掳). Based on a spring-mass model, we calculated leg stiffness, which is defined as the ratio of maximal ground reaction force to maximum center ...
The dynamic stretching I recommend does not hold the stretching position (reached after an active motion) more than 2s. Therefore it cannot be considered as bouncing stretching, where a certain amount of active stretching movement repetitions are performed once the static stretching position is reached...
Introduction: The Delayed Onset Muscle Soreness consists in a sensation of muscle discomfort resulting from the practice of intense physical exercise that lasts for some days. Static stretching can be used to try to diminish this post-exercise effect, ho
Flexibilityis defined as a range of motion around a joint. Stretchingis ameansof increasing flexibility. A limited range of motion can compromise your volleyball playing skills or affect your ability to speed up or slow down when making plays on the court. ...
are the lack of a warm-up and the fact that the dynamic stretch they used contained a static element at end-range. Although the amount of research available is limited, it is difficult to justify the use of dynamic stretching as a means of increasing flexibility based on the results of bo...
The Marun anticline is divided into eight sectors, stretching from East to West. The following wells were selected for core sampling: W507N (No. 351) and W465N (No. 263) in Sector 1, W358N (No. 63) in Sector 2, W293N (No. 292) in Sector 3, W13N (No. 20) and W149N (No...
Very successful and competitive implementations for the elastic analysis of plate stretching and plate bending problems have been achieved using complete sets of orthonormal Legendre polynomials [5,6], Daubechies wavelet systems [4], systems of wavelets defined on the interval [7] and polynomial wavel...
The surface tension minimises the surface area of the bubble while buoyancy forces resist the surface area minimization trend by stretching the bubble along the vertical axis. The importance of the gravitational force compared to the surface tension is described by the Bond number, Bo=ΔρgR02/γ...
The engineering stress (σΕ) and engineering strain (εΕ) are defined as [1.1]σE=FAo [1.2]εE=L−LoLo where F is the applied load, Lo and Ao are the initial length and cross-sectional area respectively, and L is the instantaneous length of the specimen. The true stress (σT) ...
When static stretching may help Loren Chiu, a U of A biokinesiologist, agrees the research is conclusive that static stretching of amusclemakes it temporarily weaker. However, if you aren't flexible enough to perform the task properly, he said static stretching might not be a bad idea. "It...
