Multiple Time Scale Models in Sport and Exercise Science

In sport and exercise research, examining both within- and between-individual variation is crucial. The ability to investigate change both within competitive events and across a competitive season is a priority for many sport researchers. The aim of this article is to demonstrate an approach to analyzing intensive longitudinal data collected through time-scale-dependent longitudinal designs. Following didactic presentation of the approach, two illustrations from secondary data analysis are used to describe the modeling process in detail. Illustration 1 includes affective response data from an exercise intervention randomized pilot study. Illustration 2 uses referee and player distance data collected during professional soccer games in the English Premier League. Each illustration describes a process for testing and comparing multiple time scale models based on the three-level multilevel model, and results are interpreted. In the discussion, advantages and limitations of the approach are highlighted.     

OPTIMUM DESIGN OF FLEXIBLE PAVEMENT STRUCTURE BY FLEXIPLEX TOLERANCE METHOD

The optimum design for flexible pavement structure is studied by using themethod of mathematical programming.The mathematical model is founded on the basisof“Design Code of Highway Flexible Pavement”issued by the Ministry of Communica-tions of China.The objective function is the cost of pavement structure.The optimal solu-tions of the mathematical model were searched successfully by flexiplex tolerance method.The relevant program has been developed on DPS-8 and IBM-PC computers.And thecalculated results show good convergence and accuracy for engineering applications.     

一种新的扩展复数正交空时分组码

Recent research challenges in the wireless communication include the usage of diversity and efficient coding to improve data transmission quality and spectral efficiency. Space diversity uses multiple transmitting and/or receiving antennas to create independent fading channels without penalty in bandwidth efficiency. Space-time block coding is an encoding scheme for communication over Rayleigh fading channels using multiple transmitting antennas. Space-time block codes from complex orthogonal designs exist only for two transmitting antennas. This paper generalizes a new complex orthogonal space-time block code for four transmitting antennas, whose decoding complexity is very low. Simulations show that the generalized complex orthogonal space-time block code has low bit error rate, full rate and possibly large diversity.

The Reporting and Analysis of Research Findings for Within–Subject Designs: Methodological Issues for Meta–Analysis

Abstract

The results of studying the older athlete provide inference to the possible physiological limits found at various ages and the effect of physical activity on the aging process. As a result of the increase in development of atherosclerosis with age and the high intensity effort involved in track competition, the importance of a maximal stress test prior to entering into competition was discussed. The results presented showed 40- to 75-yr-old champion track competitors to have excellent performance, cardiopulmonary function, and body composition characteristics when compared to sedentary and moderately trained subjects of similar ages. Although maximal performance and oxygen intake decreased with age, a dramatic reduction did not occur until after age 65. Body composition measures, maximal pulmonary ventilation, resting heart rate and blood pressure, and serum lipids were similar for subjects up to age 65, but showed a significant decrement thereafter. The causes of the decrement in performance and physiological function with age could not be determined, but were thought to result from a combination of factors, e.g., aging, quantity and quality of conditioning, and number of years in continuous training.
