“…These results are similar to those collected during the SBS 90° execution mode. However, our results in the SBS 270° and the SBS 180° execution mode are higher than the above-cited works [ 17 , 27 ], but they are comparable with those of Cossin et al [ 43 ] who reported 13.5 BW in vertical ground reaction force during back tucked somersault landing on three different Korean teeterboards in acrobat gymnasts.…”

The crucial criteria when assessing technical performance in artistic gymnastics is the higher elevation of the gymnast’s body and a stable landing (i.e., stick-landing). The purpose of this study was to compare kinetic and kinematic parameters during the landing phase of standing back somersaults (SBS) following three technical arm-swing performed during the preparatory phase in high-level male gymnasts. The three different arm-swing pertain to three “gymnastics schools”, i.e., Russian, Chinese, and Romanian. Six high-level male gymnasts participated in this study. Three arm-swing with different angles (i.e., SBS270°, SBS180°, and SBS90°) were randomly performed. A 3D kinetic and kinematic analysis was conducted. Results showed significant variation in the landing angle (p = 0.009) across the three arm-swing techniques. The SBS90° arm-swing resulted in the closest angle to the vertical. Additionally, the SBS90° arm-swing technique induced the lowest horizontal and vertical force values upon landing compared to the other arm-swing techniques (SBS270°: p = 0.023 and 0.009, respectively; SBS180°: p = 0.004 and 0.080, respectively). The same was noted for the horizontal velocity (p = 0.021) with the lowest values noted for the SBS90° arm-swing technique. However, the best opening angle was observed during the SBS270° technique, since it presented the best vertical displacement. In conclusion, the SBS with a SBS90° arm-swing seems to favor a better absorption of the ground reaction force upon landing by reducing the intensity of the impact with the ground and by affording a landing angle closer to the vertical in high-level male gymnasts.

“…Acrobats must synchronize their take-off with their partner's landing, and a very low stiffness can hinder this synchronization. On the other hand, higher stiffness can result in uncomfortable impact forces for the acrobat [10]. Additionally, teeterboards are made of ash wood, a natural and inconsistent material, and their mechanical properties can vary from board to board, making it even more challenging to construct standardized teeterboards.…”

“…The European Federation of Professional Circus Schools (FEDEC) [9] recommends a low stiffness board for beginners because it minimizes timing errors. However, some professionals prefer higher stiffness to have more propulsion, while others prefer lower stiffness to avoid high loads [10], combined with an increased board angle. Teeterboards are typically tapered and made of ash wood.…”

The purpose of this study was to examine the recoil effect in jumping on a Korean teeterboard, a circus equipment resembling a seesaw. To our knowledge, our study is the first to include detailed measurements of bending movement of the teeterboard per section. Two elite acrobats performed 120 jumps while a motion capture system collected kinematic data from both acrobats and the teeterboard. Board bending angles and timing were analyzed with a Boosted Regression Tree (BRT) model to identify the most important teeterboard variables associated to jump height. The BRT model showed that both the board recoil effect and the landing of the opposite acrobat influenced 46% and 37% of the jump height, respectively. The recoil timing was found to be synchronized with the last contact at take-off. Coaches should encourage acrobats to take advantage of the recoil effect to increase jump height in Korean teeterboard.

“…For example, it is well established that landing from a jump with limited knee flexion produces a large vertical ground reaction force [ 143 , 153 ]. This high force is considered a negative by most practitioners, and techniques to reduce these peak vertical ground reaction forces are often taught [ 142 – 144 ]. However, it is unknown if the athlete is better off landing with large ground reaction forces if different strategies are used over time (e.g.…”

A Proposed Framework to Describe Movement Variability within Sporting Tasks: A Scoping Review

et al. 2022

Movement variability is defined as the normal variations in motor performance across multiple repetitions of a task. However, the term “movement variability” can mean different things depending on context, and when used by itself does not capture the specifics of what has been investigated. Within sport, complex movements are performed repeatedly under a variety of different constraints (e.g. different situations, presence of defenders, time pressure). Movement variability has implications for sport performance and injury risk management. Given the importance of movement variability, it is important to understand the terms used to measure and describe it. This broad term of “movement variability” does not specify the different types of movement variability that are currently being assessed in the sporting literature. We conducted a scoping review (1) to assess the current terms and definitions used to describe movement variability within sporting tasks and (2) to utilise the results of the review for a proposed framework that distinguishes and defines the different types of movement variability within sporting tasks. To be considered eligible, sources must have assessed a sporting movement or skill and had at least one quantifiable measure of movement variability. A total of 43 peer-reviewed journal article sources were included in the scoping review. A total of 280 terms relating to movement variability terminology were extracted using a data-charting form jointly developed by two reviewers. One source out of 43 (2%) supplied definitions for all types of movement variability discussed. Moreover, 169 of 280 terms (60%) were undefined in the source material. Our proposed theoretical framework explains three types of movement variability: strategic, execution, and outcome. Strategic variability describes the different approaches or methods of movement used to complete a task. Execution variability describes the intentional and unintentional adjustments of the body between repetitions within the same strategy. Outcome variability describes the differences in the result or product of a movement. These types emerged from broader frameworks in motor control and were adapted to fit the movement variability needs in sports literature. By providing specific terms with explicit definitions, our proposed framework can ensure like-to-like comparisons of previous terms used in the literature. The practical goal of this framework is to aid athletes, coaches, and support staff to gain a better understanding of how the different types of movement variability within sporting tasks contribute to performance. The framework may allow training methods to be tailored to optimise the specific aspects of movement variability that contribute to success. This review was retrospectively registered using the Open Science Framework (OSF) Registries (https://osf.io/q73fd).
