4/25/2023 0 Comments An underhand throwDuring play, the action is fast, and there are other players attempting to steal the ball, so there are few if any attempts at underhand throwing. One example is throwing a basketball through a basketball net. The approach used can impact accuracy, the researchers note, but there are other factors at play, as well. Humans have two basic ways of throwing-overhand or underhand. In their paper published in the journal Royal Society Open Science, Madhusudhan Venkadesan and Lakshminarayanan Mahadevan describe how they combined physics with observed results to learn which techniques work best in which situations. ()-A pair of researchers with Harvard and Yale Universities has conducted a study of optimal human throwing techniques and found which work best under which conditions.

(c) Deviations away from this curve leads to an error (δxh)2 as a function of ϕ and ω. (b) The curve of launch parameters (ϕ,ω0(ϕ)) given by equation (2.4) that exactly strike the target. The lightly shaded bands shows how uniformly distributed errors in position and velocity propagate the overarm throw is more accurate. (a) For a given target, there are generally multiple ways to strike it exactly the solid red and green trajectories are two examples using an overarm and underarm style, respectively. Keep doing it until you match the 2 motions, the throw and the shot.Error propagation in throwing depends on the trajectory of the projectile. Throw 5 to 6 balls, and then pick up your club, repeating the feel. Your arm will swing down on plane, and you will release your arm towards the target – the opposite to moving outside in the downswing, and then swinging your arms to the left of the target in the follow through.Īs I have said, forget the mechanics. Your right shoulder will be moving underneath. You will be moving your lower body first. To throw the ball towards your target, your mechanics will automatically be improving. Repeat it as often as you want until you can do it, and most importantly, have a feel for the movement. Now, simply practice the motion of throwing a ball down your target line in an underarm throwing motion.Hold a ball in your right hand, taking your address as normal, and line up to your target.The next time you are practicing at your range, take a handful of balls.I want you to forget the mechanics, develop a feel, and repeat the feel when you hit shots. The exercise I am about to show you is solely to develop a feel for not coming over the top. Having a feel for what to do, is more important than understanding the mechanics. It is great to understand the mechanics, but it is all useless if you cannot develop a feeling for the movement. Create some separation lower body to upper body, release the club etc… I guess these all sound familiar. Right shoulders moves down, and underneath. You will have had lessons, read articles, and you probably understand the mechanics of how not to come over the top. Your friends have told you, maybe you have had lessons, and a coach has told you, but you still cannot stop doing it. If so, you probably know that you are coming over the top. One of the most common faults is “Over the Top.” It creates an out-to-in swing path, causing that hated slice, which so many players suffer from.
