Question 1

What is target heart rate?

Accepted Answer

Target heart rate is the range of heartbeats per minute that optimizes cardiovascular benefits during exercise. Different intensity zones provide different benefits, from fat burning to maximum performance.

Question 2

Which max heart rate formula is most accurate?

Accepted Answer

The Tanaka formula (208 - 0.7 × age) is generally considered most accurate for adults, based on peer-reviewed research. The classic Haskell-Fox (220 - age) tends to overestimate for older adults. The Nes formula works well for active individuals.

Question 3

How do I measure my resting heart rate?

Accepted Answer

Measure your resting heart rate first thing in the morning before getting out of bed. Count your pulse for 60 seconds, or count for 15 seconds and multiply by 4. A lower resting heart rate generally indicates better cardiovascular fitness.

Question 4

What is the Karvonen method?

Accepted Answer

The Karvonen method calculates target heart rate using both maximum heart rate and resting heart rate: Target HR = ((Max HR - Resting HR) × Intensity%) + Resting HR. This provides more personalized results.

Question 5

Which heart rate zone is best for fat burning?

Accepted Answer

Zone 2 (60-70% of max HR) is optimal for fat burning because your body relies more on fat as fuel at lower intensities. However, higher intensity zones burn more total calories, which also contributes to fat loss.

Question 6

How long should I train in each zone?

Accepted Answer

Zone 1: 5-15min (warm-up/cool-down), Zone 2: 30-90min (endurance), Zone 3: 20-60min (cardio), Zone 4: 10-30min intervals, Zone 5: 30sec-5min intervals. Always warm up before high-intensity training.

Question 7

Can I train at max heart rate?

Accepted Answer

Training at true maximum heart rate (Zone 5) should only be done in short intervals and if you are already fit. Most people cannot sustain max HR for more than a few minutes. Always consult a doctor before high-intensity training.

Question 8

What affects heart rate during exercise?

Accepted Answer

Factors include fitness level, age, medications (especially beta-blockers), temperature, humidity, altitude, stress, caffeine, and hydration. Heart rate also varies between activities (running vs. cycling).
