“…During ground support, a reduced rate of COM elevation, increased knee extension velocity, and increased knee flexion are also observed, which are likely a result of striking the ground further in front of the body (142). Finally, the approach toward maximum velocity during the late acceleration phase is characterized by further reductions in GCT, SF plateauing, and maximal values of FT and SL being attained (11,14,143,161). In addition, the reduced range of motion (ROM) observed at the hip will see increasing contributions of the lower leg during this phase (142), which may be explained by the greater need for the foot to aggressively strike the ground in a backward motion to apply high GRFs within close proximity of the COM (89).…”

“…Pertinently, given the intermittent nature of soccer match play, the majority of sprint efforts occur within distances of 20 m (53,184,199), which limits the attainment of maximum speed. Consequently, to adhere to the principle of specificity, the development of acceleration in the context of soccer is a priority (13,14,185) and has led to the proposal of subphases within acceleration, where distinctions in biomechanical characteristics have been identified (11,14,119,141,142). In professional soccer players, Bellon et al (14) established statistically different transitions in sprint characteristics as the progression within the specific distances that categorize the early (0-2.5 m), mid (2.5-6 m), and late (6-12 m) subphases of acceleration.…”

This review provides a definition for multidirectional speed (MDS) and evaluates its technical and mechanical underpinnings. This review explores each component of MDS while considering unique aspects of youth physiology and epidemiology. With a theoretical understanding of MDS, practitioners will be more informed on the planning and periodization of MDS training methods in soccer. MDS comprises linear speed, change of direction speed, curvilinear speed, contextual speed, and agility, which each have distinct physiological, biomechanical, and neurocognitive distinctions that can either be differentiated or harmonized to optimize training.

“…Horizontal accelerations and decelerations are locomotor skills enabling athletes to execute rapid changes in velocity and direction, and are therefore crucial to sports requiring random intermittent multi-directional (RIMD) movement demands [1,2]. As players perform frequent short-distance sprints during match play, horizontal acceleration ability is often regarded as the most critical skill for RIMD sport athletes [3,4]. Accordingly, prior research has extensively examined the biomechanical and neuromuscular qualities underpinning superior horizontal acceleration ability in RIMD sport athletes [5][6][7][8][9][10][11][12][13], culminating in numerous evidence-informed guidelines on how to best monitor, train and coach this skill [4,[14][15][16][17][18][19].…”

Biomechanical and Neuromuscular Performance Requirements of Horizontal Deceleration: A Review with Implications for Random Intermittent Multi-Directional Sports

et al. 2022

Rapid horizontal accelerations and decelerations are crucial events enabling the changes of velocity and direction integral to sports involving random intermittent multi-directional movements. However, relative to horizontal acceleration, there have been considerably fewer scientific investigations into the biomechanical and neuromuscular demands of horizontal deceleration and the qualities underpinning horizontal deceleration performance. Accordingly, the aims of this review article are to: (1) conduct an evidence-based review of the biomechanical demands of horizontal deceleration and (2) identify biomechanical and neuromuscular performance determinants of horizontal deceleration, with the aim of outlining relevant performance implications for random intermittent multi-directional sports. We highlight that horizontal decelerations have a unique ground reaction force profile, characterised by high-impact peak forces and loading rates. The highest magnitude of these forces occurs during the early stance phase (< 50 ms) and is shown to be up to 2.7 times greater than those seen during the first steps of a maximal horizontal acceleration. As such, inability for either limb to tolerate these forces may result in a diminished ability to brake, subsequently reducing deceleration capacity, and increasing vulnerability to excessive forces that could heighten injury risk and severity of muscle damage. Two factors are highlighted as especially important for enhancing horizontal deceleration ability: (1) braking force control and (2) braking force attenuation. Whilst various eccentric strength qualities have been reported to be important for achieving these purposes, the potential importance of concentric, isometric and reactive strength, in addition to an enhanced technical ability to apply braking force is also highlighted. Last, the review provides recommended research directions to enhance future understanding of horizontal deceleration ability.

Purpose. Inter-limb differences may decrease sports performance. there is a need to understand the comparison of asymmetries between open and closed skill tasks. the study investigated inter-limb step asymmetry responses to closed and open skill acceleration sprint running tasks. Methods. 3D motion analysis kinematic data of step characteristics were collected from 20 male soccer players (mean ± SD: 21 ± 1.9 years, 78.7 ± 7.7 kg, 1.78 ± 0.06 m) for bilaterally located lower-limb markers during the initial 20 m of closed and open skill acceleration sprint running trials. Step velocity, step length, step frequency, flight time, contact time, and flight distance were calculated. In the closed skill conditions, players knew the final sprint distance before initiation. In the open skill conditions, players were informed of the final sprint distance (20 or 40 m) immediately after run initiation. Results. Significant asymmetries (0.10-10.3%, p < 0.05) in step characteristics were observed during closed skill acceleration sprint performances. Positive correlations (r: 0.51-0.77, p < 0.05) were evidenced between asymmetry scores in the closed skill and in the open skill 20-m and 40-m conditions. Asymmetry scores were not associated with sprint performance (r: from -0.13 to 0.30, p > 0.05), suggesting that asymmetry may be functional or dysfunctional. Conclusions. Skilled soccer players can regulate step characteristic asymmetries across closed and open skill tasks. Symmetry should not be assumed when assessing open and closed skill acceleration sprint performance in soccer players. Practitioners should be aware of these asymmetries when implementing programmes.
