Latest Research and Professional Practice in Athlete Conditioning

Here is another great video, this time regarding the importance of strength training, and its relationship to power and sports performance. This video is taken from Professor Robert Newton’s keynote address at the Asian Conference on Sports Science in Hong Kong, October 2013.

Some key points from the video I identified:

  • Stronger athletes show an increased power output during the Jump Squats (r = 0.73 – 0.97)
  • An increase in force = increase in power shift in the force-velocity curve – an increase in peak power & power across all velocities and forces
  • A decrease in exposure to a maximal stimulus  = a decrease in muscle activation
  • Stronger athletes (1RM:BM = 1.97) show increase in maximum power compared to weaker athletes (1RM:BM = 1.28)
  • Stronger athletes show rapid increases in power in as little as 3 weeks, whereas weaker start to improve power after 7 weeks
  • Stronger athletes adapt faster to power training with greater magnitude
  • Strong athletes who stopped strength training got weaker (ES = 0.91)
  • The rate of rise in activation is key in rate of force development & power output – this links to the above that there must be an exposure to a maximal stimulus in training
  • Stronger athletes manage the eccentric load during stretch shortening cycle movements more efficiently – they are able to increase concentric force as a result, compared to weaker athletes
  • Stronger athletes are able to increase force at a given eccentric velocity & increase the velocity of the descent, allowing them to use the eccentric phase more efficiently to generate an increase in power during sporting movements
  • Stronger athletes are able to increase unloading, they can tolerate high stretch loads they generate during quick eccentric actions and use this to translate momentum into force, resulting in an increased stiffness, eccentric force, rate of force development, and power
