PeerJ

BackgroundPrior to the 2017 table tennis season, each participant performed the anterior, posteromedial, and posterolateral the star excursion balance test (SEBT) reach distances in a randomized order. The aim of this study was to assess the effects of table tennis multi-ball training and dynamic balance on performance measures of the SEBT for the male and female.MethodsThe limb lengths of the 12 table tennis athletes were measured bilaterally in the study. Besides warm-up end, the data of this study were recorded at a regular interval at approximately 16 min for the entire multi-ball training session, and they were defined as Phase I, Phase II, Phase II, respectively. The Borg rating of perceived exertion (RPE) scale was used to document the degree of physical strain.ResultsReaching distances showed a decrease with training progression in all directions. Compared with the male table tennis athletes, the females showed poorer dynamic posture control, particularly when the free limb was considered with the right-leg stance toward posterolateral and posteromedial directions in phase I.DiscussionThis study suggests that during table tennis multi-ball training the male should have a regulatory protocol to compensate the deficit observed in phase II, but the females should be given the protocol in phase I.

“…17 , 18 Table tennis cross step—the foot closing to the incoming ball as a support, regulating its tiptoe points to the direction of movement, then following the other foot strides out to the same direction—is frequently executed to counterattack the ball coming from a longer distance. 19 The biomechanical comparison of cross step patterns between the professional athletes (PA) and novice athletes (NA) would be a valuable tool in understanding the internal mechanisms involved in mastering cross step and identifying the key factors underlying effective performance.…”

“…In terms of kinetic energy, the biomechanics of lower limbs determine the level of swing performance through the kinematic chain pathway. 20 , 21 In recent years, some research studies have investigated the kinematic and kinetic characteristics of table tennis utilizing generic musculoskeletal models, comparing the differences between standing and squat serves in female table tennis athletes, 18 the effects of performance between the long and short chasse steps with table tennis forehand topspin strokes, 22 joint and plantar loading during cross-court topspin forehands with the footwork of cross step, one step and side step, 19 and comparison about lower-limb kinematics performing two different kind of forehand top spin: long-line and cross-court. 23 However, a reliable multi-segment musculoskeletal model of the foot was developed, which meets the researchers’ demands to provide an in-depth investigation of the internal mechanisms of the feet.…”

“…This information would help the coaches and players to understand internal mechanisms and enhance the performance characteristics. Based on the previous studies, 19 , 22 , 32 it can be hypothesized that (a) both PA and NA would show different plantar foot joint angles in the three motion planes at the key technical events, respectively and (b) PA would perform smaller joint range of motion (ROM) and faster joint angular changing rate during the cross step. In addition, compared with NA, it was also hypothesized that PA would exhibit distinct plantar peak pressure and relative load at the forward and swing phases.…”

Mechanical character of lower limb for table tennis cross step maneuver

The agile footwork is a basic but important skill, how to efficiently grasp and improve its performance has always interested coaches and athletes, beginners particularly. The purpose of this study was to investigate the differences in kinetics and kinematics of the cross step between professional athletes and novice athletes using the Oxford foot model. Twenty-two male participants (professional athletes, 11; novice athletes, 11) with dominant right feet participated in the table tennis cross step test. A Vicon motion analysis system and a Novel Pedar insole plantar pressure measurement system were used to record kinematic and kinetic data, respectively. Professional athletes showed significantly smaller forefoot plantarflexion and abduction, but larger hallux dorsiflexion at the cross step ending. In addition, they also showed significantly larger forefoot dorsiflexion and adduction but smaller forefoot eversion as well as rearfoot inversion than novice athletes at the forward-end of the step. In the entire motion, professional athletes performed significantly smaller joints range of motion, especially the hindfoot with respect to tibia angles. Concerning plantar relative load, professional athletes were significantly greater than that of novice athletes in the other toes, lateral forefoot and rear foot. Professional athletes possessed higher footwork agility and greater foot motor technique. The findings on the internal mechanisms of the cross step could help coaches and novice athletes understand the mechanical efficiencies in stroke finishing leading to improvements in performance.

“…Kibler [21,22] found that any disruption of the kinematic chain could induce an increased loading of other joints in the sequential movements of body segments. Lam et al [23] investigated the footwork effects on lower-limb kinematics and kinetics, which would provide useful guidance for the creation of training protocols and further understanding of the injury mechanisms. Generally, stretching is widely considered to be an effective warm-up strategy before strenuous exercise [24,25].…”

Lower Limb Maneuver Investigation of Chasse Steps Among Male Elite Table Tennis Players

Background and objectives: The popularity of table tennis has increased globally. As a result, the biomechanical movement patterns in the lower limb during table tennis have attracted extensive attention from coaches, scientists and athletes. The purpose of this study was to compare the differences between the long and short chasse steps in table tennis and evaluate risk factors related to injuries in the lower limb. Materials and Methods: Twelve male elite athletes performed forehand topspin strokes with long and short chasse steps in this study, respectively. The kinematics data of the lower-limb joints were measured by a Vicon motion analysis system. The electromyograms (EMG) of six lower-limb muscles were recorded using a myoelectricity system. Results: The key findings were that the angle change rate of the ankle in the long chasse step was faster with a larger range of motion (ROM) in the coronal and transverse planes. The hip was also faster in the sagittal and transverse planes but slower in the coronal plane compared with the short chasse step. In addition, the vastus medialis (VM) was the first activated muscle in the chasse step. Conclusions: The hip and ankle joints in the long chasse step and the knee joint in the short chasse step have higher susceptibility to injury. Moreover, tibialis anterior (TA), vastus medialis (VM) and gastrocnemius (GM) should be sufficiently stretched and warmed prior to playing table tennis. The results of this study may provide helpful guidance for teaching strategies and providing an understanding of potential sport injury mechanisms.
