Available in PDF, EPUB and Kindle. Book excerpt: Background: Anterior cruciate ligament (ACL) injury frequently occurs in female soccer athletes during deceleration movements such as landings. In soccer, landings mostly occur following jumping headers. Little research has been done to determine the mechanics that follow and how they compare to standard drop vertical jumps (DVJ). The purpose of this study was to analyze differences between jumps and landings in kinematics, kinetics, and muscle activation patterns in female soccer athletes to better assess the sport-specific risk for ACL injury. It was hypothesized that more biomechanical tendencies associated with ACL risk factors would emerge from soccer-specific vertical jumps (SSVJ) compared to DVJs and second landings (L2) compared to first landings (L1). Methods: 8 female participants (20.88 ± 1.17 years; 1.68 ± 0.06 m; 58.77 ± 7.65 kg) performed DVJs and SSVJs. Motion capture, force, and electromyography (EMG) data were collected to calculate joint motion, loading, and muscle activation throughout landing phases. Data were analyzed using RM-ANOVA, collapsed across jump (DVJ vs. SSVJ) and landing (L1 vs. L2). Results: Significant findings were revealed in all categories, however, kinematic variables were the most profound results. Significantly higher jump height was achieved in DVJs (p=0.008). SSVJs and L2s produced less peak hip (p=0.03; d=0.817) (p=0.007; d=1.566) and knee 2 (p=0.002; d=0.732) (p=0.002; d=1.476) flexion during landing, respectively. A significant interaction was present for trunk flexion at initial contact (p=0.034). Follow-up tests revealed no significant differences following headers. Discussion: SSVJ-L2s displayed a more erect landing at the hip and knee, a known ACL risk factor, however, it is unclear whether these results are due to trunk movement during heading. Limited results in kinetic and EMG variables may be explained by the difference in jump height achieved, therefore further investigation in a more elite population is required. Additionally, SSVJs may be a good sport-specific screening tool.

Book excerpt: In order to develop a stimulating yet effective school-based program which elicits a positive bone growth response, we need to understand the forces acting on the bones of children during various high-impact activities. One activity found to promote bone growth is drop landings from a height. We determined whether there are other jumping activities that exhibit similar loading properties to those of a drop landing and identified the effects of number of feet used, continuity, and direction on loading. Twenty-one healthy children (11 boys, 10 girls; age 7-9 years) were recruited from the local population. After warming up, each child performed five trials of 13 types of jumps as motion capture and ground reaction force data were collected. One type of jump was a drop landing from a 61 cm-high platform. The other 12 types were performed from the ground and comprised all possible combinations of three factors: direction (vertical as high as possible, forward a distance of 80% body height, sideways a distance of 55% body height), feet used (1-footed hops, 2-footed jumps), and continuity (discrete, continuous). The average peak force and peak loading rate at the hip of the dominant limb over five trials were computed and normalized to body weight for analysis. Three-way ANOVA identified loading differences across direction, feet used, and continuity among the 12 jump types. Paired t-tests with a Bonferroni correction compared the loading for each activity to that of the drop landings. In general, peak forces and loading rates during landing were greater for hops than for jumps, greater for discrete than for continuous hops/jumps, and greater for forward than for vertical hops/jumps. However, peak forces did not differ between sideways hops and jumps, nor did peak loading rates differ between vertical hops and jumps. Peak forces during the drop landings exceeded those during all other jumping activities except the discrete forward hop, which had peak forces similar to the drop landing. Although discrete forward hops had greater peak loading rates than the other 11 activities from the ground, the rates were less than those during the drop landings. Likely, the need to arrest the body's large forward momentum using a single limb upon landing of the discrete forward hop elevated loading over the other 11 conditions and made it comparable to that of the drop landing. Knowing what factors influence impact forces and loading rates on the hip, specifically that discrete forward hops have high forces similar to those for drop landings, will aid in developing a stimulating and effective jumping program for improved bone development in children.

Book excerpt: The purpose of this investigation was: 1) to investigate the maximal ground reaction force (GRF) when ballet dancers land from two jump conditions in pointe shoes, flat technique shoes, and barefoot; and 2) to explore if particular pointe shoe characteristics (e.g. shoe age, shank style) have an effect on the GRF of these jump landings. Twenty-one healthy, female college ballet majors from an elite program volunteered for this study. Two jump conditions were studied, these included an assemblé jump (a jump from one foot to two feet) and a grand jeté jump (a large jump from one foot to the other foot.) Three shoe conditions were studied; these included barefoot, flat technique shoes, and pointe shoes. Each dancer performed three assemblé jumps in each shoe condition, and three grand jeté jumps in each shoe condition, landing onto a recessed force plate. Vertical jump height and horizontal jump distance were also analyzed through video recording and Dartfish Version 6 software (Dartfish, Alpharetta, Georgia, USA). Order of jump and shoe condition trials were counterbalanced. Peak GRF (N) was measured and recorded. The subjects also completed a health history questionnaire and a ballet shoe questionnaire. The health history questionnaire contained questions regarding general health status, activity, and previous injury history, and the shoe questionnaire included information concerning specifics of the pointe and flat technique shoes used. Means and standard deviations of GRF were calculated for each trial. Separate repeated measures analysis of variance were calculated for each dependent variable. Each had two within subjects factors: shoe type, at three levels; and jump type, at two levels. One-way analyses of variance were performed on the specific pointe shoe characteristic data. Tukey post hoc test was completed on significant findings. For all calculations, the alpha level was set at a priori of p
