Which statement is true about technology in sport performance analysis?

• A. Video analysis and wearables quantify both technique and effort, providing objective feedback.
• B. Video analysis measures only technique, not effort.
• C. Wearables cannot quantify effort in real time.
• D. Data privacy is not a concern when using performance data.

Answer: (A)

Technology in sport performance analysis uses video analysis and wearables to assess both how a movement is performed and how hard the body is working, providing objective feedback. Video analysis lets you break down technique frame by frame—angles, timing, balance, and form—so you can see exactly what needs improvement. Wearables collect data during training or competition, such as heart rate, pace, distance, cadence, accelerations, and power, giving real-time measures of effort and training load. Together, they create a fuller picture: you can connect technique with level of effort, monitor progress, and tailor training accordingly. The other statements aren’t as accurate because video analysis can reveal aspects beyond technique and wearables can quantify effort in real time, and performance data should be protected due to privacy considerations.
