Interview with Brad Kearns
Key points:

  • DNA testing to understand what sports one is best suited for ( Training to one’s DNA profile will significantly improve response to exercise. Badly adapted training program may result in injuries, overtraining and burnout.
  • Reducing intensity to less than aerobic threshold will boost testosterone, improve fat burning and improve endurance. Aeorbic theshold is lower than the more widely refered to anaerobic threshold. Aerobic threshold can be estimated as 180 minus age bpm.
  • Aerobic threshold is quite low for untrained individuals, and may require walking instead of running. But as the body adapts, speed will increase at the same heart rate. Pro-athletes may look like they go fast, but may still have a quite low intensity
  • Low intensity builds endurance and fatburning capacity and does not trigger the body’s immune responses, meaning that the body quickly recovers and can take more training
  • Usain Bolt tells in his autobigraphy that he has always been a lazy athlete flaking a lot of sessions (ie taking it easy). The decreased stress may be important for his success, as it enables harder intensities in hard sessions
  • 20% of training should be above aerobic threshold – significantly above (polarized training).
  • Doing the 80/20 split ensures that you can go really hard on the hard days, which is required to improve speed.
  • In anaerobic sport (eg. high jumping) athletes do very few repetitions. Same things may be applied in shooting, which requires high concentration and accuracy. As each repetition is very demanding, focus should be on precision and power rather than volume.
