Muscular power (upper and lower body) and performance in the hammer throw
No full textThis file was last viewed in Adobe Reader 7.0The relationship between upper body power, lower body power, and performance
in the hammer throw was studied. At a late season NCAA track and field meet, nine
athletes from Division III universities, with at least one year of experience in throwing
the hammer, were the subjects for this research. Within one hour after each of the
subjects completed all their competitions for the day, including the hammer throw, they
performed the standard Wingate test on a Monarch cycle ergometer and a modified
Wingate test on a modified cycle ergometer to determine muscular power in both the
lower and upper body respectively. Data was then analyzed in Microsoft Excel’s
spreadsheet and software. A correlational analysis was completed to determine the
relationship of the mean differences (within each gender grouping) between performance and PR, performance and R-total (standard and modified Wingate), performance and peak anaerobic power (W/kg) (standard and modified Wingate), and anaerobic capacity (W/kg) (standard and modified Wingate). Statistical levels of significance were determined at the 5% level.
From the women’s results, correlations of statistical significance at the 5% level were found with performance and PR (0.977), performance and standard Wingate R-total (0.698), performance and standard Wingate Peak AnC (0.7003), and performance and standard Wingate Rel AnC (0.7666). Correlations were not significant between performance and all three modified Wingate results: R-total (0.2738), Peak AnC (0.3288), and Rel AnC (0.2875).
From the men’s results, correlations of statistical significance at the 5% level
were found with performance and PR (0.944), performance and standard Wingate R-total (0.804), performance and standard Wingate Peak AnC (0.6833), performance and
standard Wingate Rel AnC (0.7666). The correlation of performance and modified
Wingate R-total (0.580) was also statistically significant, but the relationship was weak. Correlations were not significant between performance and the remaining modified Wingate results: Peak AnC (0.4287) and Rel AnC (0.2161).
The correlations between performance and R-total, Rel Peak AnP, and Rel AnC
for the standard Wingate, were very strong for both the female and male subjects. The
modified Wingate, upper body test, only moderately correlated performance to R-total for the male subjects. This study indicated that the desired power for throwing the hammer related strongly to lower body power. This tends to suggest that lower body power would be a better predictor of current performance, and that future performance would be greatly influenced by training the lower body for higher power outputs
Large water-hammer pressure for column separation in pipelines
No full textWater-hammer pressures in a pipeline due to the collapse of a vapor cavity adjacent to a valve are investigated. A water-hammer event is initiated by the closure of a valve in a simple reservoir-pipeline-valve system. The sequence of events following an instantaneous valve closure leading to the formation and collapse of a vapor cavity and the resultant occurrence of a short-duration pressure pulse are described. Short-duration pressure pulses result from the superposition of the valve-closure water-hammer wave and the wave generated by the collapse of the vapor cavity. The resulting maximum pressure may exceed the Joukowsky pressure generated from the initial valve closure. A series of numerical model analyses exhibiting short-duration pressure pulses are presented. In addition, experimental results supporting the findings of the numerical studies are also presented. Experimental plots of hydraulic grade line versus time exhibit short-duration pressure pulses of different shape and characteristics.Angus R. Simpson and E. Benjamin Wyli

Do Chimpanzees Use Weight to Select Hammer Tools?

The funders had no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript.The extent to which tool-using animals take into account relevant task parameters is poorly understood. Nut cracking is one of the most complex forms of tool use, the choice of an adequate hammer being a critical aspect in success. Several properties make a hammer suitable for nut cracking, with weight being a key factor in determining the impact of a strike; in general, the greater the weight the fewer strikes required. This study experimentally investigated whether chimpanzees are able to encode the relevance of weight as a property of hammers to crack open nuts. By presenting chimpanzees with three hammers that differed solely in weight, we assessed their ability to relate the weight of the different tools with their effectiveness and thus select the most effective one(s). Our results show that chimpanzees use weight alone in selecting tools to crack open nuts and that experience clearly affects the subjects' attentiveness to the tool properties that are relevant for the task at hand. Chimpanzees can encode the requirements that a nut-cracking tool should meet (in terms of weight) to be effective.Peer reviewe
