After the moment of forward, the player moves the hand back to the prepared position To describe and assess the certain events with the cycle, the movement with the playing and subsequent cycle begins. The phases in between defined events are as follows: (1) back to ready hand was observed: (1) the prepared position is starting position,backswing hand isn’t movposition phase (in between the forward and prepared positions); (two) exactly where the phase (amongst ing after the prior stroke, and hitting phase swing back; backswing and Accmax); ready position and backswing); (three)just just before the (amongst the(2) backswing, that is the moment when the hand (amongst alterations path from backward to forward within the and (four) forward end phase stops and AccMax and forward) [5,17,18]. sagittal every angle of investigation, a population imply moment when the playing hand For plane just after the swing; (3) AccMax, which can be the standard deviation (SD) was dereaches maximumfunction of variance (NFV)forward movement; (four) forward,high/low picted. Normalized acceleration throughout the was utilised to characterize areas of when the hand stops and adjustments the path from forward for the information sagittal plane, immediately after variability (low/high repeatability) of movements, and backward in the was transferred for the stroke. After the moment of forward, the player moves the hand back to the readySymmetry 2021, 13,position and next cycle starts. The phases amongst defined events are as follows: (1) back to prepared position phase (between the forward and ready positions); (2) backswing phase (amongst prepared position and backswing); (3) hitting phase (in between the backswing and Accmax); and (four) forward finish phase (in between AccMax and forward) [5,17,18]. of 11 For every angle of investigation, a population mean typical deviation (SD)five was depicted. Normalized function of variance (NFV) was applied to characterize regions of high/low variability (low/high repeatability) of movements, plus the data was transferred to a horizontal bar representation (Figure two). Thethe standardis the typical a horizontal bar representation (Figure 2). The common CV is common CV deviation (SD) deviation (SD) divided by imply.

To overcome the problem of CV overestimation for smaller angles, for eachthe mean was shifted mean was the constructive path angles, for each angle waveform, angle waveform, the by 1SD in shifted by 1SD inside the optimistic direction resulting formula:resulting formula: and UCB-5307 custom synthesis followed the and followed theNFV = NFVSD 100 Imply SD 00 SD MeanSD(1) (1)The adopted convention was that: The adopted convention was that: NFV 20 was interpreted as low variability (dark blue colour around the horizontal bar) NFV 20 was interpreted as low variability (dark blue colour on the horizontal bar) 20 NFV 40 = average variability (blue colour) 20 NFV 40 = average variability (blue color) 40 NFV 100 = higher variability (light blue colour) 40 NFV 100 = higher variability (light blue colour) one hundred NFV 150 = very high variability (really light blue) 100 NFV 150 = really high variability (really light blue) NFV 150 = really higher variability (white colour) NFV 150 = extrem.
