It’s time to put more power into your driving force Here's another viewpoint on American Football: "Consider, as an example, a tackle in American football, rugby, judo or other contact sport. To perform a quality tackle, the driving force comes from the legs and the grasp is performed by the arms. However, the trunk ensures that the leg power can be transferred through to the grasp, thus delivering the tackle's impact with little energy dissipation and less injury risk. The same is true of many other sports and activities. The power comes through the trunk."
Don't agree in this case cause the roots can't act as the two powerful legs. Instead the roots provide stability, not altogether unimportant!
The upper arm may be king in racquet head speed in a smash but the tables may be turned when you do a net push, whether forehand or backhand. In a net push the hand (thumb, palm, fingers) and wrist are the main contributor to racquet head speed. The wrist also can do many things the forearm and upper arm cannot do for a variety of strokes. Things like cocking and uncocking of the wrist, deception, changing the angle of the racquet's contact with the shuttle, and last second directional changes are some examples.
One of the 9 extrinsic muscles is the Extensor pollicis longus, and its primary action is extension at MP (metacarpophalangeal) & IP (interphalangeal) joint of thumb. There are another 8 extrinsic muscles. One of the 10 intrinsic hand and wrist muscles is the Flexor pollicis brevis and its primary action is flexion at MP joint of the thumb. There are 9 other intrinsic muscles with different actions. Without muscles we would not be able to use chopsticks or even use the various grips in badminton.
Yes I agree that the wrist and the fingers are essential for the types of strokes that you just mentioned especially in the change of direction of the shuttle, delicate net plays or in executing a deceptive slice. Such strokes require relatively less power as the smash.
Yes, but they should have included that analysis in the results and discussion. Loh, what are you doing here? Are you hiding from those villainous kittens ?
I'm sorry, but i don't really understand how internal rotation in the upper arm, and the internal rotation of the forearm is performed. Could someone please explain to me, i would really like to know thank you.
You need to focus on channeling lots of torso and leg power into your shot. try to twist your hips towards your hitting side so you can swing your body into it. Also, begin with a loose grip on the racquet, and tighten your grip at the point of contact. Im not sure about snapping your wrist as Im more of an 'arm' player.
