Computerized system for time-motion analysis

Regular participation in sports is a common practice among the general population. For cardiovascular fitness, the frequency, duration, intensity and mode of the activity must be appropriate for the individual to benefit from the activity. The benefits for cardiovascular fitness are questionable in sports involving high intensity intermittent exercise of short duration. In the past, the procedures for determination of the heart rate and the time-motion characteristics of an activity were cumbersome and time consuming, thus making application to sports an inconvenience. The purpose of this project was to develop a computer based system for matching heart rate data with time-motion characteristics. The system was tested using ice hockey and squash. Subjects were observed during activity. The heart rate data during the activity were collected using a Polar Vantage XL Heart Rate monitor set to record heart rate values in 5-second intervals. The duration and type of activity were entered in the computer in real time using a coding system. Program combined the time-motion analysis with the heart rates that were downloaded from the Polar heart rate monitor. The results were summarized as follows: (1) total time at each intensity level, (2) mean duration at each intensity level, and (3) mean heart rate at each intensity level. Output from the computer program was similar to manual calculations.
