This study tracked health-related physical fitness measurements in children, including sum of triceps and medial calf skinfolds, timed 1-mile run/walk, 1-min bent-knee sit-up, pull-up, and sit-and-reach values. Results are from 409 boys and 409 girls tested in kindergarten and fifth grade, also retaining their first, second, third, and fourth grade data. In separate gender analyses, Spearman's rho correlations were significant (p < .001) for all grade level pair combinations for each variable. Five-yr tracking of adiposity and all health-related physical fitness measurements for boys and girls was generally moderate from early childhood to the upper elementary ages.

The purpose of this study was to investigate the effect of oral allithiamine administration on isokinetic parameters of muscle performance and lactate accumulation prior to, during, and in recovery from isokinetic exercise. A double-blind, counterbalanced, crossover experimental design utilizing aBiodex System 2 Isokinetic Dynamometer was used to test 15 healthy college students. Subjects orally ingested either 1 g · of a thiamin derivative, allithiamine, or a placebo for 5 days and then performed six exercise sets of knee extension and flexion. ANOVA revealed no significant differences between treatment conditions in peak torque, mean peak torque, average power, or total work performed (p > .05). Likewise, lactate accumulation was not significantly different between treatment conditions at any measurement point (p > .05). The absence of significant differences suggests that oral allithiamine administration does not enhance isokinetic parameters of muscle performance or lactate accumulation prior to, during, and following isokinetic exercise.

The primary purpose of this study was to examine adolescents' energy cost in a marching band. High school marching band participants (N=15) completed five 3-min. stages of treadmill marching, using a 57.2-cm stride length (typical standard of eight steps per five yards) as follows: without instruments at 75 m x min.(-1) and 132 steps x min.(-1) (Stage 1): without instruments at 91 m x min.(-1) and 160 steps x min.(-1) (Stage 2); carrying instruments at 75 m x min.(-1) and 132 steps x min.(-1) (Stage 3); carrying instruments at 91 m x min.(-1) and 160 steps x min.(-1) (Stage 4); and playing instruments at 75 m x min.(-1) and 132 steps x min.(-1) (Stage 5). Mean heart-rate response to an actual parade performance was similar to the mean Stage 5 treadmill heart rate (n=6). With regard to a high school marching band, these results suggest that energy demand for marching cadences approximates 4.5 and 6.0 metabolic equivalents for moderate and fast paces, respectively.
