為什麼您的健身追蹤器可能提供不準確的數據
Why your fitness tracker might be giving you inaccurate data
你曾否想過健康手環上所顯示的卡路里消耗量是否百分之百準確？
Have you ever wondered if the calories burned on your fitness tracker are 100% accurate?
它們仰賴專屬演算法及年齡、體重等代理數據來提供估算值。
They rely on proprietary algorithms and proxy data like your age and weight to provide estimates.
準確度往往會隨活動類型而浮動；它們在如跑步這種穩定狀態運動中表現最佳，但在如舉重這種不規則運動中則難以發揮。
Accuracy often fluctuates based on your activity type; they perform best during steady-state exercises like running, but struggle with irregular movements like weightlifting.
此外，如配戴過鬆、膚色或寒冷天氣等因素均會干擾光學傳感器，導致數據失真。
Additionally, factors like a loose fit, skin tone, or cold weather can interfere with optical sensors, leading to flawed data.
儘管有這些侷限，這些追蹤器對於監測長期趨勢與保持動力仍具價值。
Despite these limitations, trackers remain valuable for monitoring long-term trends and staying motivated.
若需要精確數據，請考慮使用胸帶式心率監測儀。
If you need precise data, consider using a chest-strap heart rate monitor.
理解這些侷限後，你便能有效運用穿戴裝置作為健身旅程的輔助，透過穩定的趨勢來檢視健康成果，而非執著於瞬息萬變的精確數值。
By understanding these limitations, you can use your wearable as a tool to support your fitness journey effectively, viewing your health progress through consistent trends instead of absolute, moment-by-moment numbers.
