歩数と速度について
速度はケイデンスと歩幅で決まります。
計算式
Speed (km/h) = (SPM × Stride Length in cm × 60) ÷ 100,000
例: 120 SPM × 75 cm = 5.4 km/h
ケイデンスとは?
ケイデンスは1分あたりの歩数です。
ヒント
- • 10歩歩いて総距離を10で割って計測
- • 走ると歩幅が長くなります
- • スマートウォッチのデータを使用

SPM to Speed Reference Chart
Quick reference for common cadence values and their approximate speeds:
| Cadence (SPM) | Stride 65cm | Stride 75cm | Stride 85cm | Activity |
|---|---|---|---|---|
| 80 SPM | 3.1 km/h | 3.6 km/h | 4.1 km/h | Slow Walk |
| 100 SPM | 3.9 km/h | 4.5 km/h | 5.1 km/h | Normal Walk |
| 120 SPM | 4.7 km/h | 5.4 km/h | 6.1 km/h | Brisk Walk |
| 140 SPM | 5.5 km/h | 6.3 km/h | 7.1 km/h | Power Walk |
| 160 SPM | 6.2 km/h | 7.2 km/h | 8.2 km/h | Jogging |
| 180 SPM | 7.0 km/h | 8.1 km/h | 9.2 km/h | Running |

Best Cadence for Weight Loss
To maximize calorie burn during walking, aim for a brisk cadence of 120-140 SPM. At this pace, a 70 kg person burns approximately 300-400 calories per hour. Research shows that increasing your walking cadence by just 10 SPM can boost calorie burn by 15-20%. Combining higher cadence with arm swinging engages more muscle groups, further increasing energy expenditure.
How Smartwatches Measure Your Cadence
Modern smartwatches and fitness trackers use accelerometers to detect the rhythmic motion of your wrist or body. The sensor counts the number of acceleration peaks per minute to calculate SPM. For best accuracy, wear the watch snugly on your wrist and swing your arms naturally while walking or running. GPS-enabled devices can also cross-reference cadence with distance to estimate stride length.
Cadence Training Zones
Understanding cadence zones helps you train more effectively. Zone 1 (80-100 SPM): Recovery and leisurely walking. Zone 2 (100-120 SPM): Moderate exercise, ideal for daily health. Zone 3 (120-140 SPM): Vigorous walking, good for fitness improvement. Zone 4 (140-170 SPM): Jogging to running, cardiovascular conditioning. Zone 5 (170+ SPM): High-intensity running, competitive pace.
よくある質問
What is a good steps per minute rate?
For walking, 100-120 SPM is typical. Brisk walking is 120-140 SPM. Jogging ranges from 140-160 SPM, and running is 160-180+ SPM. Elite runners can exceed 180 SPM.
How do I measure my steps per minute?
Count your steps for 30 seconds and multiply by 2, or use a fitness tracker/smartwatch that automatically tracks cadence. Most modern devices display SPM in real time.
Does higher cadence mean faster speed?
Not necessarily — speed depends on both cadence AND stride length. A person with shorter strides at 140 SPM might be slower than someone with long strides at 120 SPM.
What cadence do marathon runners use?
Elite marathon runners typically maintain 180-190 SPM. Recreational runners usually fall between 160-170 SPM. Higher cadence with shorter strides reduces injury risk.
How can I increase my walking speed?
Focus on both cadence and stride length. Pump your arms, engage your core, and take slightly longer steps. Aim to increase cadence by 5-10 SPM per week gradually.
