63 college women served as subjects in this 7-wk. study examining the effects of static, dynamic, and proprioceptive neuromuscular facilitating stretching techniques on the flexibility of the hamstring-gastrocnemius muscles. Subjects were assigned to one of the 3 treatment groups and received treatment 3 days a week. A pretest, a midtest (after 11 treatment days), and a posttest (after 21 treatment days) were administered. Analysis of group and test effects was accomplished by using a 3 X 3 factorial design with the group factor nested and the test factor crossed. Post hoc analysis indicated that all scores significantly improved from pretest to posttest. The findings indicated all 3 methods of flexibility training produced significant improvements when pretest and posttest mean scores were compared.

The subjects were 32 college student volunteers all assessed to have normal or corrected normal visual abilities. Each subject reacted to each of five variously colored balls 100 times per day over a 2-day period. These balls randomly appeared at one of four locations in the subjects' visual field. Analysis indicated that the effect of color was nonsignificant. The location of stimuli was significant; faster reactions occurred at the locations closest to the subjects' point of fixation.

To improve putting performance, golfers have often used goal-setting techniques which require realistic performance expectations. Thus, examining whether external factors such as putting green irregularities affect putting performance is crucial to goal setting. The purpose of the study was to examine fluctuations in the trueness of roll of a golf ball across a green. A ball was mechanically rolled across a green in the morning and afternoon on a day when there was normal play and on a day when the course was closed to play. Analysis indicated that significant fluctuations in distance and dispersion were present throughout these time frames, i.e., the greatest distance of roll and the least amount of dispersion were present in the morning and on the day closed to play. Golfers should take into account these external fluctuations in trueness of roll when establishing goal-setting procedures involving putting skills.

The differences in sit and reach flexibility scores among boys and girls aged 3 through 8 yr. were investigated. Analysis indicated that the sit and reach flexibility test was a reliable measure across trials and sessions for the 300 subjects. Analysis of variance indicated the 3- to 4-yr.-old subjects were significantly more flexible than subjects aged 5 to 8 yr. Also, girls were significantly more flexible than boys across the three age groups. These findings remained significant even when leg/torso and arm/torso ratios served as covariates.

10 bogs and 10 girls ( 6 0 subjects) were randomly selected from kindergarten, first, and second grades. Each subject attempted to catch balls of 6-, 8.5-, lo-, and 13-in. diameters through 28 trials (seven attempts per ball per subject). A special apparatus was designed to roll the ball consistently into the subject's arms fron: a horizonral distance of approximately 4 ft. The quality of each attempted catch was evaluated using a five-point scale. The main effects of ball size, grade, and sex were significant. A linear trend described the relation of ball size and grade. The over-all quality of the catching performance improved from kindergarten to second grade and from the small ball to the larger sizes.
