This study was designed to measure the effect on range of motion of a single massage treatment to the hamstring muscle group. Thirty-four normal female subjects between 18 and 35 years of age were given a 9- 12 minute massage treatment to the posterior aspect of one randomly assigned lower extremity. Passive range of motion of both lower extremities was measured by taking the perpendicular distance from the lateral malleolus to the table surface in a straight leg raise and by conventional goniometry for hip flexion and knee extension. Measurements were taken pre-, and post-, and 7-days postmassage treatment. Immediate postmassage increases in range of motion were noted in the test group (massaged) legs with significance at the 0.05 level. The possible uSe of this treatment in athletics and pathological conditions are discussed.

Literature Review
Jessie VanSwearingen
As a group, adolescents demonstrate notoriously poor dietary habits. Sports and exercise participation actually encourages young people to attend to nutritional concerns. Nutritional factors play a major role in determining the adolescent's potential to reach full growth and the maintenance of good health. In addition to the effect on growth, food intake (quantity, quality, and pattern of) is a critical determinant of athletic performance. A review and synthesis of the recent literature concerning characteristics of adolescent athletes and the nutritional requirements of growth and performance are provided. Common nutritional deficiencies of the young athlete and dietary inadequacies resulting in disturbances of growth are identified. Maximal athletic performance and the promotion of the present and future good health of young people challenges health and fitness professionals to provide adolescents with accurate nutritional information and caution against widespread nutritional frauds.

A new case of isolated paralysis of the anterior interosseous nerve of a 24-year-old man is described. It is thought that this was caused by a fall on the left arm. This paralysis has a typical clinical picture with a characteristic disturbance of the pinch grip. The patient recovered spontaneously. A review of the findings previously reported in the literature is presented.

The authors studied the effects of high speed (240°/sec) and low speed (60°/sec) isokinetic exercise. Twenty-four subjects were randomly selected into one high speed and one low speed treatment group; treatments consisted of one set of 15 repetitions, 3 times a week for 6 weeks. Pre- and post-testing with a Cybex II isokinetic dynamometer was performed to determine if significant strength gains were elicited at 30, 60, 180, 240, or 300°/sec. Both low and high speed groups produced significant strength gains (0.0 1 significance level) at their treatment speed and at one testing speed higher. However, this study indicates that the range of this carry over is not sufficient enough to replace speed-specific training.

Thirty subjects with no pathology of the right elbow were tested using an isokinetic dynamometer to measure wrist extensor strength. Subjects were tested under control and experimental conditions with and without a forearm strap. Tests were conducted at 30 and 120°/sec. Results were plotted on separate graphs using a sequential trials method. No difference in strength was noted at the slower speed. A statistically significant increase in strength with the strap was found at 120°/sec. It was concluded that, in these subjects, the forearm strap made no difference in strength at the slower speed, but significantly increased strength at the faster speed. Facilitation due to sensory stimulation of the skin and pressure on the muscle belly was offered as an explanation. Further research is needed in this area.

The purpose of this study was to determine the effects of knowledge of results, i.e., visual feedback from watching the torque curve on the Cybex II recorder, on knee extensor and flexor strength (peak torque in ft-lb), and fatigue (strength decrement) during reciprocal, isokinetic testing at speeds of 15O/sec (slow) and 300°/sec (fast). Knowledge of results induced higher strength and fatigue values in both muscle groups during slow, but not fast, speed tests. The greater amounts of fatigue resulted from elevated initial strength levels at the beginning of the slow speed fatigue tests. The superior quality of the slow speed knowledge of results and longer times to utilize the visual feedback may explain the enhanced strength values. The effect of knowledge of results on strength levels decreased during the course of the slow speed fatigue tests. Results are discussed in terms of information processing and motivation theory.

The cold laser, HeNe, 6328 AU, was used in an attempt to enhance open lesion healing. In both cases cited, planned surgery was cancelled because of the effectiveness of the lasings. Suggested techniques and procedures are outlined.
