Solution Overview

Problem

Existing techniques fail to predict athletic performance based on a subject's physiological state before a competition, specifically lacking correlation between pre-competition parasympathetic activity and performance in athletic activities.

Innovation Solution

An athletic activity performance estimation device that acquires tension state information, calculates a tension state index, and estimates performance indices using pre-defined correlations to predict performance based on the subject's state before the activity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If existing techniques use post-competition or random-day physiological measurements, then some correlation with performance can be found, but accurate pre-competition performance prediction is not achieved

Engineering Contradiction:

Improveperformance prediction accuracyVSAvoidtime for performance prediction

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The invention measures physiological parameters (heart rate, skin conductance, respiration) before the athletic competition to predict performance in advance. This preliminary measurement approach allows athletes and coaches to know the expected performance level before competition, enabling timely adjustments in strategy, training, or physical state without waiting for post-competition analysis.

Inventive Principle:

Principle #10Preliminary action

2Loss of information

If physiological measurements are taken during competition season, then some performance correlation can be established, but the specific pre-competition state cannot be evaluated

Engineering Contradiction:

Improvepre-competition state informationVSAvoidperformance correlation accuracy

Core Design Contradiction:

Loss of informationVSMeasurement precision

Solution Approach 1:

The system provides feedback about the athlete's pre-competition physiological state by measuring parameters such as heart rate, skin conductance, and respiration rate. This feedback loop allows the athlete to understand their current tension state and make real-time adjustments to achieve optimal performance conditions before the competition begins.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

By conducting physiological assessments before competition, the system captures the specific pre-competition state that directly influences performance. This preliminary evaluation of tension state, heart rate variability, and other parameters provides actionable information that can be used to optimize performance before the athlete steps onto the field or court.

AI summary

An athletic activity performance estimation device estimates an athletic activity performance index relating to an athletic activity in which a subject performs a short-time action after a predetermined waiting time using information correlated with the state of tension of the subject as tension state information, an index indicating the subject's tension level as a tension state index, and an index indicating the quality of performance of an athletic activity of the subject as the athletic activity performance index. The athletic activity performance estimation device includes a tension state information acquirer that acquires the tension state information of the subject before starting the athletic activity, a tension state index calculator that calculates the tension state index of the subject from the tension state information, and an athletic activity performance index estimator.
