Isometric shoulder strength in young swimmers

Journal of Science and Medicine in Sport, 2018
The 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, 1987
Isometric 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 ...

Variability of grip strength during isometric contraction

Ergonomics, 1995
The use of measures of strength variability as a means of determining sincerity of effort is becoming a more common practice, particularly in medico-legal and rehabilitation settings. The stability of such variability measures, however, has not been documented.

Isometric back strength in different age groups

International Disability Studies, 1991
Normative data on isometric back strength (IBS) are presented. The IBS of both sexes increased with chronological age, peaked at the third decade of life, and gradually declined thereafter. Males were significantly (p less than 0.001) stronger than females in all age groups, the difference ranging between 16 and 56%.

Isometric strength and occupational muscle disorders

European Journal of Applied Physiology and Occupational Physiology, 1988
In two longitudinal studies, initial muscle strength and endurance of the shoulder-forearm muscles were related to deterioration of shoulder-neck-arm disorders after one year. Group I (n = 32) worked in the automobile industry assembling car motors. Their work was performed when standing and walking, and implied varied postures and exertion of external

Reliability of Isometric Strength Testing Temporal Factors and Strength Variation

Clinical Orthopaedics and Related Research, 1984
Isometric strength measurements of grip, pronation, supination, and elbow extension and flexion on dominant and nondominant sides were made on 40 normal subjects (age range, 40-70 years) to investigate the variability of isometric strength at different times of the day.

Isometric Strength Testing

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, 1966
Abstract 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 ...

Level of Maximum Isometric Strength and Relative Load Isometric Endurance

Ergonomics, 1969
Forty-seven male college students were tested for maximum isometric strength and relative load isometric endurance of the right elbow flexor muscles at 50, 60, 70 and 80 per cent of their maximum strength level. Three groups were formed based on the maximum isometric strength of the subjects.

Isometric Strength Test Consistency over Time

Proceedings of the Human Factors Society Annual Meeting, 1983
Workmen's Compensation costs have become a major financial burden on industry. A significant part of these costs are the result of musculoskeletal injuries. One method of controlling these injuries is matching employees to jobs based on strength.
