Understanding the Inputs

Ensure accurate power measurements for reliable results

  • Body Weight (kg): Your current body weight in kilograms for normalization of power output.
  • 30s Max Power (W): Maximum average power output (watts) during a 30-second all-out effort.
  • 5min Power (W): Steady-state power output (watts) maintained during a 5-minute effort.

Complete Guide: Anaerobic Capacity Training

Anaerobic capacity represents your ability to produce high power for short durations (10–60 seconds). Improve it through short sprints, hill sprints, plyometrics, heavy weight training, and high-intensity intervals. Limit to 2–3 sessions per week with adequate recovery, as anaerobic work is highly fatiguing. Balance with aerobic base training for overall performance.

Frequently Asked Questions

Detailed, SEO-oriented answers

What is anaerobic capacity?

Anaerobic capacity is your ability to produce high power output for short durations (10–60 seconds) using energy systems that don't require oxygen. It's crucial for sprinting, jumping, and explosive movements.

How is anaerobic capacity calculated?

This calculator uses the difference between 30-second max power and 5-minute steady power, normalized to body weight. The formula: (Power30s − Power5min) × 30s / (Body Weight × 1000).

What is a good anaerobic capacity value?

Values vary by sport and individual. Higher values (≥2.0 kJ/kg) indicate excellent power output. Track your own improvements over time.

How do I test for anaerobic capacity?

Perform a 30-second all-out effort on a bike ergometer, rower, or similar device. Also test 5-minute steady power. Enter both values with body weight.

Does body weight affect the calculation?

Yes, capacity is normalized to body weight (kJ/kg) to allow comparisons across different body sizes.

Can I improve anaerobic capacity?

Yes, through short sprints, hill sprints, plyometrics, heavy weight training, and high-intensity interval training.

How often should I train anaerobically?

Limit to 2–3 sessions per week with adequate recovery. Anaerobic work is highly fatiguing and requires proper rest.

Is anaerobic capacity the same as power?

Related but distinct. Power is instantaneous output; anaerobic capacity reflects sustained high power over 10–60 seconds.

Can endurance athletes benefit from anaerobic training?

Yes, adding anaerobic work can improve finishing kicks, hill climbing, and overall power-to-weight ratio.

What recovery is needed between anaerobic sessions?

Allow 48–72 hours between intense anaerobic sessions. Monitor for overtraining signs like persistent fatigue or declining performance.
