Generally, the best stick length is for the shaft to be the length of your arm; however, just a standard stick length seems to work best for most people. sured during a maximal isometric contraction (MVC or maximal voluntary contraction) of the same muscle, prior to dynamic testing4,5. A second way of analyzing the throwing motion is kinematics, the branch of mechanics that deals with the motion of a body without reference to force or mass6. Researchers will use high-speed camera systems and markers.
For every action there exists an equal and opposite reaction. When throwing a lacrosse ball, the stretch in the netted pocket and the motion of the ball counteracts the force put into swinging the stick. The ball gets forced forward as a reaction to the work applied to the stick. Generally, the best stick length is for the shaft to be the length of your arm; however, just a standard stick length seems to work best for most people. If you cut it to your arm length, it makes it easier to maneuver. But, a really good lacrosse player can maneuver the stick regardless.

The throw-in is a unique. throwing motion in that both hands must be used, the ball must. come from behind the head forward, and both feet must maintain. contact with the ground until release as stipulated by the laws of. the game (FIFA, ). In this experiment, you will test whether an average person is able to make a lacrosse ball achieve a higher velocity by shooting it with a lacrosse stick or throwing it barehanded, similar to a baseball pitch. Write a hypothesis in one or two sentences predicting the outcome of the experiment and explaining your prediction scientifically.

[John Robert Stevenson]. regardless of the motion of the stick or the length of the stick. The purpose of this study was to measure ball speed and 3-D stick kinematics during lacrosse shots by vari-ous male and female players and to calculate the speed at the tip of the lacrosse stick, assuming the lacrosse stick behaves as a rigid body.
We hypothesized thatFile Size: KB. Twelve elite male lacrosse players participated in this study. Kinematic data were sampled at Hz, while two-dimensional force plates collected ground reaction force data ( Hz).
Statistical analysis showed significantly greater ball velocity for the sidearm technique than overhand (P Cited by: 2.

Effects of center of mass kinematics on ball velocity during jump throwing in handball. MOJ App Bio Biomech. ;2(3)‒ DOI: /mojabb Results and discussion This study was carried out to investigate the relationships between body center of mass kinematic parameters and ball velocity during jump throwing in handball.

Resisted Sprints and Effects on Kinematics and Sprint Speed; Arm Path and Pitching Velocity not to throw at maximum velocity.
Throwing for maximum distance requires an optimal combination of release speed and release angle, not a maximum release speed. long toss decreases pitching velocity when the case study clearly lists the average. The average maximum run up speed of an elite thrower ranges from m/s (20km/h), but elite throwers release the javelin at m/s (km/h) Author: Mike Barber.
Well, like you said, the speed is just the magnitude of the velocity vector at any point, = sqrt(vx^2 + vy^2). So if the ball was thrown right with some initial vy and a vx of 35 m/s, at its peak, vx would be 35 m/s (assuming no air resistance) and vy would be 0.

increases in ball velocity would be problem-atic since minimal amounts of protective equipment are worn. To date, there have been few biomechanical investigations of the lacrosse stick (Stevenson III, ) and none that have focused on throwing kinematics and changes in crosse design.
The purpose of this study was to examine the effect of such. A recent biomechanical study shows that pitching slightly underweight and overweight baseballs can produce variations in kinematics (specifically arm, trunk, pelvis, and shoulder velocities) without increased arm kinetics (Fleisig et al., ) and that maximum-effort crow-hop throwing with the same implements can increase shoulder internal rotation angular velocity and elbow varus Author: Joseph A.

The lacrosse stick (or crosse) is used to propel, catch, pick up and retain possession of a – g solid core ball. In women's lacrosse, speed gun data indicate that the ball is propelled at a rate of 11–14 m s −1 (40–50 km h −1) during a pass and at higher rates (i.e., 25–31 m s −1 or 90– km h −1) when shot on by: 7.
Background Weighted-baseball training programs are used at the high school, collegiate, and professional levels of baseball. The purpose of this study was to evaluate the effects of a six-week training period consisting of weighted implements, manual therapy, weightlifting, and other modalities on shoulder external rotation, elbow valgus stress, pitching velocity, and : Joseph A.

The next topic I wanted to look at was if materials used in the pocket of the stick itself made a significant difference. Lacrosse stringing up until the ’s hadnt really changed too much since the birth of the sport hundreds of years before that. -Work= Force x Distance -More distance of the long pole mean more work -Less protection of the stick -Less stick control Long Pole -Defensive Players -6 ft Prezi The Science.Kinematic and Kinetic data are often analyzed within a phase in order to compare and contrast different types of pitches, for example (e.g., 10).
Presently, there is no such description of the phases and discrete events of the lacrosse shot.Five findings of kinematic studies: 1. In girls’ lacrosse especially, many stick and body impacts occur without a penalty. 2. Previously, most impacts in boys’ lacrosse were due to helmet-to-helmet contact, as gleaned by filming nearly 1, games.
