工作原理
- 1
Enter your age in years.
- 2
Enter your current heart rate in beats per minute.
- 3
The calculator computes your maximum heart rate as 220 minus your age.
- 4
It then divides your current heart rate by your maximum heart rate and multiplies by 100 to get the intensity percentage.
(current_hr / (220 - age)) * 100常见问题
What is the maximum heart rate formula?
The most common estimate is 220 minus your age. It's a rough guide; actual max can vary.
What intensity should I train at?
Moderate intensity is typically 50-70% of max heart rate, vigorous is 70-85%. Consult a professional for personalized zones.
Can I use this for any exercise?
Yes, it's a general guide for aerobic activities. For precise zones, consider a heart rate test.

公式
此计算器背后的数学公式，供您核对结果。
Maximum Heart Rate
A simple estimate of the highest heart rate you can achieve during exercise.
Example:
Input: Age = 30
Calculation: 220 - 30
Result: 190 bpm
Training Intensity
Shows what percentage of your maximum heart rate you are working at.
Example:
Input: Current HR = 140, HRmax = 190
Calculation: (140 / 190) × 100
Result: 73.7%
实际应用场景
此计算在日常生活中的应用。
Monitor workout intensity
Ensure you're training in the desired heart rate zone for your fitness goals.
Example: Aim for 70-85% for high-intensity intervals.
Avoid overtraining
Keep intensity within safe limits to prevent injury and burnout.
Example: Stay below 90% for most sessions.
Track progress
As fitness improves, the same effort may produce a lower heart rate, indicating better efficiency.
Example: Compare intensity at the same pace over time.
提示与常见错误
Tips
- Use a heart rate monitor for accurate readings.
- Warm up before checking your heart rate during exercise.
- Your max heart rate is an estimate; individual variation is normal.
- Combine intensity with duration for total training load.
Common Mistakes to Avoid
- Using resting heart rate instead of current exercise heart rate.
- Assuming the 220-age formula is exact for everyone.
- Ignoring other factors like medication or altitude that affect heart rate.
假设与限制
- Use the stated inputs and units.
- Results are estimates for planning and education.
- Check measurements and source data before making an important decision.
