Isometric Pull-Push Strengths in Workspace: 1. Strength Profiles [PDF]
International Journal of Occupational Safety and Ergonomics, 2004 The isometric pull and push strength profiles of males and females were determined in seated and standing positions in the workspace. The strongest pull strength location was at extreme reach vertically above the shoulder for both males and females.

Isometric Strength and Relative Isometric Endurance
Research Quarterly. American Association for Health, Physical Education and Recreation, 1971Abstract Thirty-six male college students served as subjects in a study that examined the relationship between isometric strength and relative isometric endurance of the right forearm flexor muscles. The percentages of maximum isometric strength used for the endurance tests were 30, 45, 60, and 75.

Isometric exercise, isometric strength and anthropometric measurements
Internationale Zeitschrift f�r Angewandte Physiologie Einschliesslich Arbeitsphysiologie, 19631. 29 young adult male subjects practiced 15 sec. of maximal isometric contractions of the elbow flexors three times a day, 5 days a week, for 5 weeks. They achieved greater increases in strength than have been claimed for a single two-thirds maximal contraction once a day, although the latter has been said to provide the maximal stimulus for the ...

Reproducibility of Isometric Strength: Measurement of Neck Muscles
Clinical Biomechanics, 1999To evaluate the repeatability of an advanced method of measuring the strength of functionally different groups of neck muscles using an isometric apparatus.A repeated measures design was used within and between sessions.Chronic neck pain has been associated with poor isometric neck strength.

Isometric shoulder strength in young swimmers
Journal of Science and Medicine in Sport, 2018The prevalence of shoulder pain in young swimmers is high. Shoulder rotation strength and the ratio of internal to external rotation strength have been reported as potential modifiable risk factors associated with shoulder pain. However, relative strength measures in elevated positions, which include flexion and extension, have not been established for

Isometric Elbow Strength in Normal Individuals
Clinical Orthopaedics and Related Research, 1987Isometric elbow strength was measured with torque cell dynamometers in a group of 104 normal subjects. Their mean age was 43 years (range, 21-79 years). Test functions included elbow flexion and extension, forearm pronation and supination, and grip. In general, the men were twice as strong as the women, and the dominant extremities were 6% stronger ...

Spine, 1986
Back injuries occurring during isometric strength testing motivated a statistical analysis to determine if a reduction in the number of exertions during the test was possible without profound influence upon the accuracy of the results. Strength measurements from more than 1,000 volunteers in an industrial back pain study were examined. It was concluded

Level of Isometric Strength and Isometric Endurance in Repeated Contractions
Research Quarterly. American Association for Health, Physical Education and Recreation, 1966Abstract Thirty male subjects were given 20 trials of isometric wrist flexion on each arm. Each trial consisted of 5 sec. of maximum exertion followed by a 30 sec. rest period. Subjects were ranked on the basis of the first two trials for each of the limbs and divided into three groups of 10 subjects each representing high, middle, and low levels of ...
