Study Notes

External Sensors and Injury Prevention

External sensors are used to try and predict and prevent injuries in athletes.
Long training loads can lead to injuries, but too little training results in poor performance.
Wearable technology enables better characterization of training.
Machine learning algorithms analyze data to predict injury risk or optimal training loads.

Wearable Devices in Boxing

A study used wearable sensors (accelerometers and gyroscopes) on boxing gloves and wrists.
Machine learning algorithms analyzed sensor data to predict the type of punches thrown.
Accuracy of prediction was about 90%.
This demonstrates sensors can differentiate different striking patterns.

Acute-to-Chronic Workload Ratio

This ratio compares short-term (acute) workload to long-term (chronic) workload.
It's calculated by measuring training volume in recent days/weeks to the preceding months.
External measures are used to determine this ratio.
It helps predict injury risk.
High ratios (above 1.5, especially 2.0) indicate a high risk of injury.
A ratio of 1.0 suggests the current training week's workload is similar to the training load of the past month.
Coaches and trainers use this data for planning better training regimens.

Workload and Injury Risk

Recent studies suggest a measurable relationship between acute-chronic workload ratios and injuries.
Athlete and team coaches use this to manage training loads appropriately.
The workload ratio can help predict injury risk.
A ratio above 1.5 or 2.0 signals a higher risk of overuse injury
