Shoulder impingement occurs when you recover your elbow. High elbow should point to the sky, in front of your chest and at the side of the body (green line), NOT leaning towards the back (orange line). The latter causes the humerus (long upper arm bone) to poke into the socket of the shoulder and long term injury known as swimmers shoulder will occur once there is inflammation of SITS (Supraspinatus, Infraspinatus, Teres Minor and Subscapularis) muscles that stabilizes shoulder hold the arm in place.Red lines shows the legs are opened up, not together and thus causing drag.
Left arm is too deep when breathing.
White line being the streamline position, the legs and arms are way off.. :)The video was short on your side but i took it on impulse. Still, it doesn't matter if its long or short as swimming is such a habit-based exercise, every single stroke will look exactly the same. Thus having 1 stroke is more than enough to see how you will fare for the whole lap.
Good news is since you're very tall and have long limbs, the biomechanical advantage helps you to overcome some stroke problems but when you do serious long D swims, all those advantage can turn into Disadvantage as long limbs in bad position causes MORE drag than those with smaller and shorter body and limbs. Thus wastage of energy.
Welcome to sapphire swimming team and hope to see you again next wednesday!

Wow, i never saw myself swim before...frankly, it look all over the place. Quite a shock, coz it didn't feel like this in the water. Really appreacite the pointer.
ReplyDeleteI just picked up swimming 5 mths ago, before that i can only do the crawl for 25m and then my heart rate will be racing at 180BPM.
Great to know the mistakes, this mean i should be able to go faster without working any much harder, right? I'm lazy by nature, but i like continual improvement.
currenly in Taipei for work, see you next wed.
