“…This involved the simultaneous collection of the subject’s vertical ground reaction force and accelerometer data. Indeed, the frequent requirement to perform unexpected or anticipated cutting maneuver (CM) while running or engaging in outdoor activities poses a significant risk of injury ( Nagano et al, 2016 ). Previous studies have confirmed that there is a greater risk during 90° CM.…”

Introduction: Given the possibility of higher ground temperatures in the future, the pursuit of a cushioning material that can effectively reduce sports injuries during exercise, particularly one that retains its properties at elevated temperatures, has emerged as a serious concern.Methods: A total of 18 man recreational runners were recruited from Ningbo University and local clubs for participation in this study. Frequency analysis was employed to investigate whether there is a distinction between non-Newtonian (NN) shoes and ethylene vinyl acetate (EVA) shoes.Results: The outcomes indicated that the utilization of NN shoes furnished participants with superior cushioning when engaging in a 90° cutting maneuver subsequent to an outdoor exercise, as opposed to the EVA material. Specifically, participants wearing NN shoes exhibited significantly lower peak resultant acceleration (p = 0.022) and power spectral density (p = 0.010) values at the distal tibia compared to those wearing EVA shoes. Moreover, shock attenuation was significantly greater in subjects wearing NN shoes (p = 0.023) in comparison to EVA shoes. Performing 90° cutting maneuver in NN shoes resulted in significantly lower peak ground reaction force (p = 0.010), vertical average loading rate (p < 0.010), and vertical instantaneous loading rate (p = 0.030) values compared to performing the same maneuvers in EVA shoes.Conclusion: The study found that the PRA and PSD of the distal tibia in NN footwear were significantly lower compared to EVA footwear. Additionally, participants exhibited more positive SA while using NN footwear compared to EVA. Furthermore, during the 90° CM, participants wearing NN shoes showed lower PGRF, VAIL, and VILR compared to those in EVA shoes. All these promising results support the capability of NN footwear to offer additional reductions in potential injury risk to runners, especially in high-temperature conditions.

“…The accelerometer was secured to the upper back of the participant using an exclusive vest with compressive inner wear that did not prevent their upper or lower limb movements [15]. We selected trunk acceleration as a variable indicating musculoskeletal load because it more reliably assesses GRF than knee acceleration does [11], and it does not prevent the upper and lower limb movements of athletes during measurement. The three axes of the accelerometer were aligned close to the anatomical axes i.e.…”

“…Simons and Bradshaw reported that the impact load during jumping and landing tasks and GRF could be reliably assessed using accelerometry [9,10]. Moreover, vertical acceleration during change of direction can potentially reflect gender differences and stiff cutting movement [11]. Inertia sensors demonstrating excellent accuracy counting volleyball-specific jumps is an example of its application during sports activity [12][13][14].…”

“…Therefore, using these methods, high-impact movements and evaluation of these movements can potentially be evaluated to define physical load during sports activity. However, these previous studies were conducted in a laboratory setting [9][10][11] or did not show the details of the high-impact movement increasing the physical load during the volleyball match [12][13][14].…”

History:Objectives: Detection of the frequency or intensity of high-impact movements during volleyball match would help understand physical load causing the injuries. The present study aimed to classify different volleyball-specific high-impact movements based on the measurement of trunk acceleration in a volleyball match as a cross-sectional study.Methods: Linear accelerations of six female volleyball players were measured during a single volleyball match. The instances at which >4G and >6G of resultant acceleration was generated were detected. Movements recorded with a synchronized video were also detected and categorized. Counts (cases) and frequencies (cases/min) of the detected movements were calculated, and the resultant and each directional acceleration among the top seven volleyball-specific detected movements were compared.Results: For attackers, 361 and 97 movements were detected for the resultant acceleration thresholds over 4G and 6G, respectively. Landing, takeoff and running were the top three detected movements in both thresholds. Landing was the most frequently observed high-impact movement, and the ratio of landing over 6G was greater among all detected movements compared with the ratios of landing over 4G threshold. For receivers, 297 and 38 movements were detected for the resultant acceleration thresholds over 4G and 6G, respectively. Running, steps on the spot, and steps forward or backward were the top three detected movements. The top seven detected volleyball-specific movements generating over 4G were landing after blocking, landing after spiking, takeoff before spiking, takeoff before blocking, stationary steps during receiving, steps forward or backward during receiving and sidesteps during receiving. Resultant and vertical accelerations of landing after spiking were significantly greater than those of the other six movements (p < 0.001). Conclusions:Using the results of present study, we were able to estimate the physical load causing injuries during a real volleyball match.

“…No unified view has been obtained on an index of acceleration. Peak resultant acceleration (PRA) is an index measure reflecting high-impact movements, gender differences, and stiff cutting movements [15]; it is also correlated with ground reaction force [11]. In volleyball, PRA also reflects individual differences in jumping and non-jumping movements [10]; whereas in badminton, the frequency and details of high-impact movements were estimated using PRA [16].…”

This study aimed to identify the high-impact details of play and movements with higher acceleration and their frequency during a female basketball match. Trunk acceleration was measured during a simulated basketball game with eight female players. The extracted instance was categorized, which generated at > 6 and 8 G resultant accelerations using a video recording and an accelerometer attached to the players’ trunk, as details of play and movements. The frequency and ratio of the details of play and movements regarding all detected movements were calculated. A total of 1062 and 223 play actions were detected for the resultant acceleration thresholds of > 6 and 8 G, respectively. For these acceleration thresholds, in terms of details of play, positioning on the half-court was the most frequently observed (29.6 and 23.8%, respectively). In terms of movements, deceleration was the most frequently detected movement (21.5 and 23.3%, respectively), followed by landing (7.6 and 15.7%, respectively). Deceleration during positioning on the half-court and defense as well as landing mostly after a shot were detected as high-impact frequent basketball-specific movements. The results also showed that characteristics of movements or playing style and playing position may have an effect on acceleration patterns during a basketball game.
