correct position for L-sit

Bruce Craven is an owner of Craven Sports Services. He and his wife Karen have worked with gymnasts for decades.

Currently Bruce is assisting male gymnasts at Taiso Gymnastics Saskatoon. As always he’s focused on training the correct muscles for each element. And contracting those muscles in the best sequence.

monitoring height in Gymnastics

Dr. Dave Tilley reports on monitoring for peak height velocity in his Gym.

Dave’s been tracking 3 numbers for each of the growing kids:

• height
• seated height (torso length)
• wing span

At MINIMUM your gymnasts age 10-17 should have a place in the Gym where they pencil in their standing height on some regular basis. They should know when they are growing. There are implications for training load.

If you want to research this topic, get Handbook of Sports Medicine and Science, Gymnastics. (2013).

Gymnastics – safest landing positions

Dr. Dave Tilley is concerned:

… the unfortunate reality is that the typical way gymnasts were taught to land growing up (me included) may not be the safest for them and most effective to stick skills. Not to mention coaches are also unfortunately very mis-informed about what the best available science suggests for proper landing mechanics. The concerning typical landing position that we need to move away from is one of

• Knees and feet together
• Glutes engage with the “hips tucked under” into hollow
• Knee dominant landing strategy
• Stiff impact with upright torso

… The reality of the situation is that we need to change the way gymnasts land, starting from a very young age. The more ideal landing we should be teaching and forcing athletes to use is

• Feet hip width apart
• toes, knees, hips, and shoulders close to inline (generally)
• core engaged in relative neutral (not excessively hollowed or arched)
• proper angular displacement of the hip and knee joints
• hip angle generally 30 degrees, and trunk / tibial lines close to parallel …

Why Gymnasts Must Change How They Land

With greatly increased difficulty being competed now and into the future, obviously the “best” landing positions are the ones that bring impact forces to zero with the least risk of injury, especially major injuries like ligament ruptures.

Most of the top male gymnasts in 2016 land their difficult skills in a very typical way.

Check these successful WAG landing positions. (Some are luck, of course. But many are skillful.)

balancing activities can improve memory

Climbing a tree and balancing on a beam can dramatically improve cognitive skills, according to a study recently conducted by researchers in the Department of Psychology at the University of North Florida. …

The results of this research, recently published in Perceptual and Motor Skills, suggest working memory improvements can be made in just a couple of hours …

A sample — “The Mechanics of Impact“:

… The effectiveness of the take-off sets the uppermost limits of what the gymnast can hope to obtain during the airborne phase of any skill. During this moment, the path (trajectory) followed by the performer’s center of gravity, as well as the quantity of rotary motion (angular momentum) available for skill execution, are irrevocably established. …

Once the gun has been fired, there is no turning back…for the trajectory and momentum of its bullet are irrevocably established! …
