Abstract
Overview:
The dynamic systems perspective suggests that an individual’s movements are unique and identifiable. An effective mover is one who is able to adeptly free and freeze joints to meet the current requirements of the task.
Problem:
Accepting the complex systems view, the problem then is to describe the effectiveness or quality of an individual’s squat exercise. A potential solution could be found by utilizing insights from the product and the process of movement. The product or quantity of movement during a squat were gained through triaxial accelerometer values and process or quality of movement was achieved through Lower Extremity Functional Scale questionnaire describing the self- perception of movement. The problem of this study was to provide a holistic description of movement and effectively describe the relationship between two different metrics.
Methodology:
The Spearman Rank Correlation Coefficient provided the ideal method to compare data from two different value systems. An Excel analysis provided one significant correlation between accelerations to perception ratings. Recognizing the potential for greater comparisons, a Python program was written. Using values from the program meta-analysis revealed interesting patterns of correlation otherwise not seen. Currently, the challenge is to analyze this massive amount of data and create a quality of movement model.
Discussion:
To determine movement quality, we first established a mental model or predicted patterns of the movement. Using mathematical algorithms data can be simplified to represent patterns of movement for the individual. Comparing these numerical values to self-perception of movement, mathematical analysis provided a rating of movement quality. Such findings could provide meaningful insights for a more effective plan in the clinical or fitness setting. For example, training that uses values of perception and movement acceleration may be able to better address issues of unique movement patterning and therefore provide a more individualized program.
