Fifty-two rifle naïve navy personnel underwent four days of simulated M16A1 live fire training in an artificial intelligent test bed trainer, followed by one day of live fire record qualification in the field. Prior to test bed training, subjects were administered the Army Physical Readiness Test (APRT) and assessed on their current level of physical fitness. At the end of test bed training the subjects participated in one of four exercise conditions (control, walk, job, or run) designed to elevate their hart rates. Immediately following exercise they shot a 10 round self-paced task at a scaled 250 meter target. Analysis of variance indicated no significant difference between fitness levels for the shot group size and standard deviation on the self-paced task. Significant differences were found based on exercise condition and heart rate during firing. Future research should utilize experienced marksmen and the exercise manipulation should occur immediately prior to live fire.

A modified version of the Rockport Fitness Walking Test (RFWT) has been determined to be reliable for persons with mental retardation. Previous investigations have used one pacer for each participant. While this protocol may be reliable, it is not likely feasible in most school or community-based settings. Therefore, the purpose of this study is twofold: first to evaluate the reliability of a modified version of the RFWT using one pacer per five participants; second, to determine the agreement among the one to one protocol and the proposed five to one protocol. This study compared the end completion times and mean peak heart rates of three different one-mile walking sessions of 35 participants with mild mental retardation. Eighteen females (21.1 �� 2.7 yr.) and 17 males (19.7 �� 2.8 yr.) participated in each testing session. Each participant randomly completed two sessions of walking with one pacer per five participants and one session of one pacer per participant on an indoor surface 1/9th of a mile long. Results from ANOVA indicated end completion times and mean peak heart rates did not differ based on gender (p=0.798), sessions (p=0.053), and gender x sessions (p=0.855). To determine agreement, intraclass correlation coefficients (ICC) were calculated for end completion times for the first five to one and the one to one (R=0.83) and the second five to one and the one to one (R=0.85). ICC's were calculated for mean peak heart rates for the first five to one and the one to one (R=0.95) and for the second five to one and the one to one (R=0.93). The results support that the five to one modified walking protocol produces results similar to the results using the one to one testing. / Graduation date: 1998

The purpose of this study was to compare the concentration of and the time to peak blood lactate following three 90-s cycle ergometer tests--intermittent all-out (Int-A), continuous all-out (Cont-A), and continuous constant (Cont-C), and to compare group peak lactate to blood lactate at individual peak time. Eight fingertip blood samples were drawn between 1 and 12min post-exercise. Subjects were university hockey players (n = 19) and physical education students (n = 19). The two all-out tests had a higher peak concentration than the Cont-C test (P $<$ 0.05). The Int-A test had an earlier peak than the two continuous tests (P $<$ 0.05) but this difference vanished if peak time was measured from the onset of the tests. A number of sampling times had lactate concentrations similar to the individual peak concentration (P $<$ 0.05): (1) 1, 2, 3, and 4min for Int-A; (2) 2, 3, 4, 5, and 6min for Cont-A; (3) 2 and 4min for Cont-C.
