“…5a). This simulation result supports the strong correlation between the foot velocity and the ball velocity shown kinematically by Levanon and Dapena (1998). Further, independently decreasing the foot velocity immediately before impact decreased the ball rotation produced by an impact with a large attack angle, although this effect was not large (Fig.…”

“…Previous study has shown a positive correlation between the foot velocity immediately before impact and the ball velocity immediately after impact (Kawamoto et al, 2007;Levanon and Dapena, 1998). Furthermore, Ishii and Maruyama (2008) reported that the ball velocity is not affected by varying the attack angle at the same impact point, and that the ball rotation is not affected by varying the impact point with the same attack angle.…”

“…Smoothing through impact represented studies that ignore the eþ ects of impact. Polynomial extrapolation is an extension of an approach to model more accurately the points of impact in sports (Chung, 1988;Levanon and Dapena, 1998;Knudson and Bahamonde, 1999). It uses a quintic spline with no smoothing to estimate the position of impact and extrapolate the ® ve frames after impact.…”

“…Since the most appropriate smoothing depends on the speci® c kinematic variable of interest (Giakas and Baltzopoulos, 1997b), information is required on the best extrapolation conditions to model accurately the angular velocity in sport biomechanics skills involving impacts. Some recent studies have proposed polynomial extrapolations to estimate the point of impact and additional padding points to model sports impacts (Chung, 1988;Levanon and Dapena, 1998;Knudson and Bahamonde, 1999). The aims of this study were to document if smoothing through impact is responsible for the apparent decrease in racket speed before impact in tennis and to assess the accuracy of two recent techniques of impact point estimation and extrapolation.…”

Smoothing to obtain accurate position and velocity data near impacts in sport biomechanics studies is complicated by the accelerations of impact, endpoint effects and the smoothing technique used. Wrist goniometric data with two levels of random noise added were used to examine three endpoint modelling conditions for obtaining accurate position and velocity data at impact in the tennis forehand. The common approach of smoothing through impact created distortions of the position signal up to 100 ms before impact and resulted in consistent underestimations (-3.2%) of wrist angle and angular velocity (-67.9%) at impact. New linear and polynomial extrapolation conditions smoothed with all techniques provided lower root mean squared errors than the smoothing-through-impact condition, with discrete wrist positions at impact within 1.1% of the criterion data. Both the new linear and polynomial conditions can be used to make more accurate angular position and velocity estimates for tennis impacts, whereas the smoothing-through-impact condition creates spurious decreases in speed before impact that in the past have been assumed to be aspects of skillful movement.

“…Nevertheless, it should be considered that, due to the computational burden and experimental complexity, the number of participants of many analogous studies on soccer kicking varied from 6 (Levanon & Dapena, 1998) to a maximum of 21 (Kellis & Katis, 2007;Manolopoulos et al, 2006).…”

Dribbling speed in soccer is considered critical to the outcome of the game and can assist in the talent identification process. However, little is known about the biomechanics of this skill. By means of a motion capture system, we aimed to quantitatively investigate the determinants of effective dribbling skill in a group of 10 Under-13 sub-elite players, divided by the median-split technique according to their dribbling test time (faster and slower groups). Foot-ball contacts cadence, centre of mass (CoM), ranges of motion (RoM), velocity and acceleration, as well as stride length, cadence and variability were computed. Hip and knee joint RoMs were also considered. Faster players, as compared to slower players, showed a 30% higher foot-ball cadence (3.0 ± 0.1 vs. 2.3 ± 0.2 contacts · s(-1), P < 0.01); reduced CoM mediolateral (0.91 ± 0.05 vs. 1.14 ± 0.16 m, P < 0.05) and vertical (0.19 ± 0.01 vs. 0.25 ± 0.03 m, P < 0.05) RoMs; higher right stride cadence (+20%, P < 0.05) with lower variability (P < 0.05); reduced hip and knee flexion RoMs (P < 0.05). In conclusion, faster players are able to run with the ball through a shorter path in a more economical way. To effectively develop dribbling skill, coaches are encouraged to design specific practices where high stride frequency and narrow run trajectories are required.
