ABSTRACT
This follow-up study investigated whether attitudes toward the metric system have changed over the last 15 years. 132 subjects ranging in age from 18 to 45 years participated by filling out a 7-item survey designed to measure attitudes toward the metric system. Each survey item was scored using a 5-point rating, e.g., "the change to the metric system will create more problems than it solves," 1: strongly agree and 5: strongly disagree. Scores were compared to those obtained for a similar sample in 1983. Comparisons using t tests indicated no significant differences between attitude scores from 1983 to 1998 for either men (t64 = .95) or women (t133 = .06).

Two studies were conducted with the purpose of examining the validity of the 12-item Physical Estimation Scale, developed by Safrit and Wood (1985), as a predictor of running performance. Physical Estimation Scale scores were not significantly related to running time at the 5-mi. distance but were significantly correlated with predicted and actual marathon finishing times.

The effect of prohibiting the use of a preshot routine on free-throw shooting in competitive situations was investigated. 25 male high school basketball players were instructed to attempt 50 free throws alternating in blocks of 10 between the use of their preshot routine and shooting without it. To make the situation competitive, subjects were run in groups of five and their performance was recorded on a large easel placed to the side of the free-throw line. A significantly larger number of baskets were made in the preshot routine condition than without the routine. A competitive situation led to a greater decrement in baskets than had been reported in 1986 by Lobmeyer and Wassermen during noncompetitive free-throw shooting.

Body-frame size is an important factor in determining an optimal body weight for a given height. Previous studies have indicated that many individuals incorrectly estimate their body-frame size, and, as a result, incorrectly assess their ideal weight. The present study investigated the accuracy of estimation of body-frame size as a function of sex and actual frame size. The subjects were 66 men and 52 women participating in a community adult fitness program. Data indicated that medium-framed individuals were the most accurate in their estimations of body-frame size. Also, women were twice as likely to be accurate as were men. These results are interpreted to mean that most people assume they are medium-framed and that there is a sex difference in the way body-frame size is estimated.
