Anthropometric and performance data were collected on 65 US rugby players (mean age = 26.3 years) to make comparison on these characteristics by player position and performance level. Anthropometry included stature, body mass, nine skinfolds, two girths and two bone breadths. Skinfold patterns, estimated percent fat and Heath-Carter somatotypes were calculated from anthropometry. Motor performance measures included standing vertical jump, 40 yard dash, 110 yard dash, shuttle run, repeated jump in place, push-up, sit-up and squat thrust. Descriptive statistics were used for the total sample as well as selected sub-groups. Discriminant function analyses were employed to determine which combination of variables best discriminated between position and level of performance for the anthropometric and performance data. The results indicated that forwards were taller, heavier and had more subcutaneous adiposity than backs. Additionally, forwards and backs differed in somatotypes, with forwards being more endo-mesomorphic than backs and with a greater scatter about their mean. The anthropometric variables that best discriminated between backs and forwards were body mass, femur breadth and arm girth, with 88% correctly classified using these variables. The motor performance variables that best discriminated between backs and forwards were repeated jump in place, push-up and standing vertical jump, with 76% correct classification using these variables. Classification into three playing levels was unsatisfactory using either anthropometric or motor performance variables. These data can be used to assess present status and change in players, or potential national players, by position to locate strengths and weaknesses.
48 residential students a t the Kansas State School for the Deaf wete given the Brace Motor Ability Test. Sex had liale influence o n the levels of performance, while age below 7 yr. yielded significantly lower performance. The extent of hearing loss did not influence the performance.In recent years increasing effort has been made to gather information related to physical and/or mental handicaps. Initial effort to examine physical performance capacities has been made in the areas of mental retardation (6, 12) and perceptual-motor abilities (7, S ) , especially for visually impaired persons ( 3 ) .T o date, though, little information is available on motor ability of deaf individuals, particularly children in the lower elementary grades.Examination of motor capacities of the deaf was initially recorded about 1730. Paterson ( 4 ) found that deaf children were approximately 2 or 3 yr. behind hearing children in their ability to exhibit rapid movements, motor control, spatial adjustments, and eye-hand coordination. Long (9) compared the deaf and hearing on several eye-hand coordination tasks, grip strength, and balance.Balance was the only test that differentiated the two groups. Within the children tested, Long recorded that the deaf boys did better than the deaf girls.After an extended period of time in which little smdy was devoted to this topic, Boyd ( I ) , on the Oseretsky test, compared deaf and hearing boys for static equilibrium, general dynamic balance, psychomotor integration, and laterality. Ac every age, the hearing children did better on static equilibrium. O n dynamic balance, the 8-yr.-old children performed similarly, but the 9and 10-yr.old hearing children did better. N o difference was found on speed of motor functioning. T o date, little information is available on the ability of the deaf to control gross body manipulation in stunts. Lack of data is even more apparent for deaf children between the ages of 5 and 10 years. This study was designed, therefore, to assess the gross motor abilicy of selected primary school-aged deaf children. Of secondary importance were the gross effects of age, sex, and residual hearing o n the performance of these children.
The purpose of this study was to determine the physical activity participation patterns of college students when defined by their Health Locus of Control orientation. One thousand thirty-three college-aged students completed the Wellness Activity Profile, a questionnaire that yielded data on Health Locus of Control and self-reported frequency of participation in physical activities. Discriminant analyses indicated that the combination of physical activities associated with internally and externally oriented students were different for both males and females. Participation in high caloric expenditure activities was more frequent among internal subjects (Male: bicycling, volleyball, other individual sports, and snorkel/scuba diving; Female: basketball, weight training, tennis, fast walking/jogging/running, and judo/karate), while low caloric expenditure activities were associated with an external orientation (Male: baseball/softball, sailing, fishing, golf, and other recreational sports; Female: track and field jumping and fishing).
