Abstract
A running form diagnosis system capable of automatically scoring a running form of a runner is provided. The running form diagnosis system obtains body motion information as to a test subject running on a treadmill, and calculate a running form score of the test subject by applying obtained characteristics to a given operation expression. The operation expression is generated based on correlation between characteristics of a plurality of test runners and comprehensive evaluation given by an expert with respect to the plurality of test runners.
Claims11
A running form diagnosis system for scoring a running form of a test subject, comprising:
- a storage device configured to store an operation expression representing a correlation between body motion information extracted from information related to running of a plurality of test runners and evaluation given by an expert with respect to respective running of the plurality of test runners;
- an interface for receiving an input of information related to running of the test subject;
- and
- a processor configured to output a score as to a running form of said test subject based on information inputted to said interface,
- said processor being configured to:
- extract body motion information of said test subject from the information related to running of said test subject and inputted to said interface;
- calculate the score as to the running form of said test subject by applying said extracted body motion information to said operation expression;
- and
- wherein said operation expression includes:
- a first regression expression obtained by performing a regression analysis, with evaluation for two or more items given by said expert with respect to running of said test runners as an explanatory variable and with comprehensive evaluation given by said expert with respect to running of said test runners as an objective variable;
- and
- a second regression expression obtained by performing a regression analysis, with body motion information of said test runners as an explanatory variable and with respective evaluation for said two or more items given by said expert with respect to said test runners as an objective variable.
A method for scoring a running form of a test subject, the method being executed by a computer,
- said computer including:
- a storage device configured to store an operation expression representing correlation between body motion information extracted from information related to running of a plurality of test runners and evaluation given by an expert with respect to respective running of the plurality of test runners;
- and
- an interface for receiving an input of information related to running of a test subject,
- the method comprising:
- allowing said computer to extract body motion information of said test subject from information related to running of the test subject and inputted to said interface;
- allowing said computer to calculate a score as to the running form of said test subject by applying said extracted body motion information to said operation expression;
- and
- wherein said operation expression includes:
- a first regression expression obtained by performing a regression analysis, with evaluation for two or more items given by said expert with respect to running of said test runners as an explanatory variable and with a score given by said expert with respect to running of said test runners as an objective variable;
- and
- a second regression expression obtained by performing a regression analysis, with body motion information of said test runners as an explanatory variable and with respective evaluation for said two or more items given by said expert with respect to said test runners as an objective variable.
