“…Maughan et al 20) and Hakkinen and Keskinen 21) measured the size of the quadriceps muscle in different groups of athletes representing different type of sports, the authors revealed a remarkable difference in the size of the quadriceps muscle between groups of elite athletes. In another study, a significant difference in semispinalis capitis muscle size was found between elite wrestlers and elite weight lifters.…”

Abstract.Within the last century, many medical approaches have been invented and widely upgraded in the field of medical sciences. Ultrasonography is a non-invasive method in medical diagnosis which has several applications in musculoskeletal evaluation. Each ultrasonography picture is a very thin tomographic slice of the anatomy being examined. With ultrasonography an examiner is able to measure the cross-sectional area, and linear dimensions such as the anterioposterior dimension (APD) and lateral dimension (LD) of the muscle. It is also possible to calculate the multiplied linear dimension by the equation APD times LD and the shape ratio by the equation LD/APD. In biophysiological measurement ultrasonography is a digital measurement device with a high accuracy for identifying small structures. In the field of muscle research, compared to muscle strength test and surface electromyography, ultrasonography can easily screen and evaluate the individual muscle contraction even in the deep layers. During ultrasonography the muscle image is continously updated. Therefore, the method may be useful in physiotherapy of weak muscles by means of visual feedback.

“…Muscle ultrasonography has also been used to compare the size of an individual muscle in different groups of elite athletes with different training and competition programmes 17,20,21) . Another application of muscle ultrasonography is describing the association between muscle size and concerned muscle force in biomechanical studies.…”

“…There are significant correlation (r=0.72, p<0.05) in the long-distance runners, but not in the sprinters. These results suggest that peak blood lactate obtained after 400 m sprinting may be a useful indication for anaerobic work capacity in the long-distance runners, but not in the sprinters, and that performance in 400 m sprinting may depend mainly on energy supply from glycolysis in the long-distance runners, but in the sprinter it will be influenced not only by glycolysis, but also by other factors such as ATP and CP content in the muscle (REHUNEN et al, 1982) and force per unit muscle cross-sectional area (MAUGHAN et al, 1983).…”

“…In addition to the other characteristics, we used muscle length as a selection criterion for participants because a larger muscle has been shown to generate more force than a smaller muscle. 11 Because the entire size of the muscle could not be measured, we assumed that the length of the muscle represented its size. We chose the non-dominant arm for testing because the effect of daily activities in altering the strength of the muscles may be less for the non-dominant arm than for the dominant arm.…”

Purpose: The purpose of this article was to determine whether strength is altered in the upper trapezius in the presence of latent myofascial trigger points (MTrP). Methods: This study was case controlled and used convenience sampling. The sample recruited was homogeneous with respect to age, sex, height, and body mass. Participants were assessed for the presence of latent MTrP in the upper trapezius and placed into two groups: an experimental group that had latent MTrP in the upper trapezius and a control group that did not. Eighteen women (mean age 21.4 y, SD 1.89; mean height 156.9 cm, SD 4.03; and mean body mass 51.7 kg, SD 5.84) made up the experimental group, and 19 women (mean age 20.3 y, SD 1.86; mean height 158.6 cm, SD 3.14; and mean body mass 53.2 kg, SD 5.17) made up the control group. We obtained strength measurements of the non-dominant arm using a handheld dynamometer and compared them between the two groups. Results: The difference in the strength measurements between the two groups was not statistically significant (p ¼ 0.59). Conclusions:The presence of latent MTrPs may not affect the strength of the upper trapezius.
