Lumbar bone mineral density in adolescent female runners.

Background: The purpose of this study was to determine if there were significant differences in lumbar bone mineral density (L2-L4, g/cm2) or several hormones among 3 groups of adolescent females: 10 amenorrheic runners, 10 eumenorrheic runners, and 10 eumenorrheic controls.

Experimental Design: comparative.

Setting: Cooper Clinic, Aerobics Center, Dallas, Texas.

Bone density patterns in women with anorexia nervosa.

Objective: The purpose of this study was to compare various measures of bone mineral density (BMD) in adult anorectics with those of age and gender-matched controls.

Method: Twenty Caucasian females with a history of anorexia nervosa and 20 controls were evaluated by dual energy x-ray absorptiometry for lumbar and total body BMD. Regional densities were derived from total body scans.

Relationship of regional body composition to bone mineral density in college females.

The purpose of this study was to examine relationships between regional body composition and bone mineral density (BMD) in college females. Subjects were 12 nonathletic females (< 3 h.wk-1 of exercise) and 46 female varsity athletes: basketball (N = 14), volleyball (N = 13), gymnastics (N = 13), and tennis (N = 6).

The effects of gymnastics training on bone mineral density.

The purpose of this study was to examine the effect of 27 wk of gymnastics training on bone mineral density (BMD), body composition, insulin-like growth factor I (IGF-I), and osteocalcin. Subjects were 11 female intercollegiate gymnasts and 11 controls. Dual energy x-ray absorptiometry (Lunar DPX) was used to determine BMD (L2-L4 and femur) and to assess body composition.

Attitudes of handicapped and nonhandicapped high school students toward physical education.

The attitudes of 381 handicapped and nonhandicapped high school students toward physical education in mainstreamed classes were compared using measures from the Kneer Attitude Inventory and Diagnostic Statements. A two-way analysis of variance yielded a significant difference between the groups' attitudes. Nonhandicapped high school students had significantly more positive attitudes toward physical education than their handicapped peers.

Self-concepts of disabled youth athletes.

A self-concept inventory was administered to 158 youth athletes, ages 9 to 18 yr. (M = 13.94 yr.

Self-actualisation of elite wheelchair athletes.

The purpose of this study was to examine the self-actualisation of male and female elite wheelchair athletes in comparison to the general population and to able-bodied athletes. All subjects completed the Personal Orientation Inventory (POI), and statistically significant differences were identified. In general, wheelchair athletes were similar to the general population.

Use of the personal orientation inventory with disabled athletes.

Athletes who are blind or have impairments in hand-eye coordination that prevent writing are unable to complete psychological inventories in the standardized manner, i.e., read silently and answered independently and anonymously.

Peak torque values of the knee extensor and flexor muscles of females.

Two hundred and forty-one females between the ages of 18 and 28 years were subjects for this study. Subjects were tested for knee extension and knee flexion on a Cybex(R) II isokinetic dynamometer at 60 degrees /sec using a modified seating arrangement which placed the back rest at 20 from the vertical. To familiarize subjects with the Cybex II, two practice trials of complete extension and flexion were allowed.

Effects of an integrated physical education/music program in changing early childhood perceptual-motor performance.

Two approaches to facilitating perceptual-motor development in children, ages 4 to 6 yr., were investigated. The experimental group (n = 15) received 24 sessions of integrated physical education/music instruction based upon concepts of Kodaly and Dalcroze.
