每搏瓦特計算器
兩位騎士可以維持相同的功率，但以更低心率完成的那位擁有更高效的有氧引擎。每搏瓦特用一個數字概括了這一點：平均功率除以平均心率。輸入兩者，本計算器就會給出你的每搏瓦特以及每搏所做的功。在穩定強度的訓練中持續追蹤它，便能看到有氧體能在一個訓練週期內不斷提升。
每搏瓦特是平均功率除以平均心率，是衡量心臟每跳動一次能輸出多少外部做功的簡單指標。在相同心率下，每搏瓦特越高，代表有氧引擎越高效，因此隨著體能提升這個數值通常會上升。只能在相近的強度、時長與條件下進行比較；騎行過程中由於心率漂移使心率上升，這個數值會下降。
常見問題
- What is watts per heartbeat?
- Watts per heartbeat is an aerobic efficiency index that divides your average power output by your heart rate. It shows how much work you produce for each beat, so a higher value means your cardiovascular system is delivering more output per unit of effort.
- How do I calculate watts per heartbeat?
- Divide your average power in watts by your average heart rate in beats per minute over the same effort. Riding at 200 watts and 160 bpm gives 1.25 watts per beat. Enter both numbers and the calculator returns your efficiency index.
- How do I interpret my watts-per-heartbeat number?
- Compare it across similar workouts: as aerobic fitness improves, you produce more watts at the same heart rate, so the value rises. It's most useful as a personal trend rather than an absolute benchmark, since it varies with effort length, heat and fatigue.
