Tabell 3.1=table 3.1 Norwegian is easy ain't it?
Utover= thrower. I don't have that letter I replaced with an o in my keyboard and am too lazy to copy paste
Alder means age. Hoyde height of the thrower. Vekt=weight and the last column is the record throw of the player(achieevd before this test). On the second lowest row gj.snitt is short form for average. On the last row std.av. means standard deviation. For those that don't know it it is statistics and I'm not gonna detail what that is. A mathematically inclined person may have the motivation not I. It's not required to understand it for purposes of understanding what is in the graphs.
Figur 3.5 -or figure 3.5 easy like I said
only handles signal manipulation and measurement and doesn't tell anything that interesting with regards to torwing so ignore that.
Where things get interesting after showing principles in previous pictures is table 4.1Utg.hastighet means the speed at which the disc flies right after the rip in meters per second. Beside the speed is the standard deviation. The numbers come from five throws and are an average of those. Utg.rotasjonshast. is the rotational speed of the disc around it's center in degrees per second. Tillopshastighet means the speed at which the thrower is moving. Varighet kastfase means the time that it the throw takes in the period under scrutiny in this paper. That period is the time when the plant foot lands to the rip. I don't understand how Fotavstand or the lenght of the the step between the right leg and the left leg is arrived at measured ankle to ankle. I didn't understand/find the definitions here to be exact enough nor did I get anything like the numbers mentioned in the results. Armlengde means arm lenght. Again I don't understand how these results were arrived at.
Table 4.2 shows a statistically meaningful negative correlation between the speed at which the thrower is moivng relative to the rotational speed of the disc with a confidence level of 95 % if my memory serves me right about statistics.
Figur 4.1 is the first interesting graph of the results made with the measurement system. Zero degrees is where the target lies 90 degrees to the right of the throwers line of sight in the beginning. If the thrower raised his right arm parallel to the ground straight to his right it would point at the basket or target at this study. The degrees to the right of the sight line of the thrower (up in the graph because it is a top down view) are positive and to the left of the thrower negative. The vertical axis describes the angle in degrees of the twisting of body parts which are the hip represented by the blue line and the upper body rotation (under the pecs) represented by the red line. Horizontal axis shows the time passed. The vertical line on the left in the graph is when the right step plants and the right vertical line shows where the rip occurs. The graphs are for each thrower again named Utover 1 etc.
Figure 4.2 shows measurements of more moving parts. Only the hip and upper body rotations are absolute measurements compared to the global x axis of the measurement system. The other measurement are relative angles. Justwhat that means exactly I'm not 100 % sure of. The body parts represented by different lines (of too similar colors IMO) are in order from top down: Right shoulder extension, right shoulder turning back away from the target, shoulder rotation, elbow extension, elbow what? and the extension of the hand from wrist down in the end of the throw increasing the spin on the disc tremendously(the coveted big snap's end result resulting in the disc leaving the hand faster and fading later thus retaining altitude longer thus increasing the time and speed the disc stays in the air giving big D).
Table 4.3 shows hip rotation in degrees. Minimumsvinkel shows the amount of reach back from the hip in degrees with standard deviations beside the degree number. Slippunktsvinkel means the rotation of the hip at the time of the rip. Bev. utslag shows the amount of total rotation that the hip achieved.
Table 4.4 shows upper body rotation(from under the pecs), 4.5 shows horizontal shoulder movements and 4.6 elbow motions. 4.7 shows how the wrist moves.
Table 4.8 shows that there is a statistically meaningful positive correltaion between the amount of degrees that the hips turn relative to the speed and RPMs of the disc with a confidence level of 95 %.
Figure 4.3 shows the amount of degrees that different parts turn per second. The parts are in desceding order: Hip rotation, upper body rotation, right shoulder extension, elbow extension, wrist turning with negative numbers meaning turning back and positive number meaning going forward compared to the direction of movement of the player.
Figure 4.4 shows also the dis relative to the hand.
Table 4.11 shows that there is a positive correlation yada yada between the maximum turning speed of the wrist forward and the RPM that the disc achieevs. So remember to chop the elboe quickly. And do remember that correlation doesn't automatically mean causality
More later when you've had the time to digest this and if there is demand. Please say if you'd like me to continue. I wouldn't want to do work that has no benefit to anyone.
