AB - Trunk muscle strength plays a crucial role in the sport-specific movements of basketball players. While the plank test is widely used to assess trunk muscle endurance, its lack of standardization limits its effectiveness in high-performance environments. The study aimed to establish objective criteria for determining when the plank position was no longer maintained and introduced a new variable, postural error (PE). This study involved 23 (age = 15.22 years, weight = 66.3 kg, height = 174 cm) healthy female basketball players from the Hungarian U16 first league. Using optical motion capture, the thoracic kyphosis (TK) and lumbar lordosis (LL) were monitored during the test. The cutting point (CP) was determined based on four mathematical formulas and the estimation of two independent experts. PE was determined based on the area under the curves, which characterizes the magnitude of displacements until the endpoint. According to the difference between the expert-estimated and the calculated CP, the initial angles were calculated as the average of the first 15 seconds, and the CP was set at a ±25° deviation. Additionally, PE was introduced to assess the strategy of maintaining the plank posture, revealing differences in performance even among participants with similar CP times. The present study introduces a new method for determining the test's objective starting angle endpoint and introduces a new variable, PE, to characterize trunk stability, distinguishing between different execution strategies. The findings suggest that this approach provides a more reliable and objective way to assess trunk muscle endurance and core stability.

AB - Vision plays a fundamental role in the control of human locomotion, including walking gait. Given that side-dominance is associated with differences in motor control, the present study aimed to determine if patches obscuring half of the visual field affect left- and right-side dominant individuals’ gait kinematics and accompanying leg muscle activation differently. Healthy right- ( n = 15, age = 28.2 ± 5.5 years) and left-side ( n = 9, age = 27.9 ± 5.8 years) dominant participants performed 10 min of walking trials on a treadmill at a self-selected speed with 5 min of rest between three randomized trials, i.e., wearing clear glasses or glasses with left-or right half-field eye patching. In addition to a set of spatiotemporal and kinematic gait parameters, the average activity during the separated gait cycle phases, and the start and end of muscle activation in % of the gait cycle were calculated from five muscles in three muscle groups. Our results indicate that gait kinematics of left- and right-side dominant participants were similar both in their dominant and non-dominant legs, regardless of half-field eye patching condition. On the other hand, inter-group differences were found in selected kinematic variables. For instance, in addition to larger but less variable step width, our results suggest larger ankle and knee ROM in right- vs. left-sided participants. Furthermore, medial gastrocnemius and biceps femoris muscle activation showed selected differences at certain phases of the gait cycle between participants’ dominant and non-dominant legs. However, it was also unaffected by the half-field eye patching condition. Moreover, the endpoint of medial gastrocnemius activation was affected by side-dominance, i.e., its activation ended earlier in the non-dominant leg of right- as compared to left-side dominant participants. Our results suggest no major differences in walking gait kinematics and accompanying muscle activation between half-field eye patching conditions in healthy adults; nevertheless, side-dominance may affect biomechanical and neuromuscular control strategies during walking gait.

AB - Background: Physical preparation in basketball is essential but often limited by training time and prior focus on tactical and technical skills. While postural stability is known to assist injury prevention and performance, its specific impact on game-related performance remains unclear. With the development of motion analysis systems, the numerical values of external and internal loads measured during matches have become measurable. This study aimed to examine the relationship between postural stability and game-related performance and introduce a method for visualizing key competencies. Method: Twenty-three U16 female basketball players (age = 15.22 ± 0.82 years, mass = 66.3 ± 8.85 kg, high = 174.0 ± 8.2 cm) participated from the Hungarian first league. Postural stability was assessed via plank test and one minute dynamic standing balance tests, while game-related performance was monitored through match-derived internal and external load values measured by WIMU PRO™ System, alongside statistical data derived from the official box scores. After the postural stability measurements, we monitored an official basketball match, which was conducted according to official International Basketball Association (FIBA) rules. For clear and comprehensive presentation, we combined the game-related performance indicators using Principal Component Analysis (PCA). Results: A moderate correlation (0.5 < r < 0.8, p < 0.05) was found between the game-related performance and postural stability variables. However, plank test indicators showed no significant correlations with game-related performance variables, except for bad throws (r = 0.56, p = 0.037), the postural error (PE), a variable reflecting compensatory movement during fatigue in the plank test, correlated with balance indicators (r = 0.63, p = 0.014). Mediolateral balance control correlated with explosive game-related performace metrics, including maximum acceleration (r = -0.65, p = 0.01), deceleration (r = 0.56, p = 0.035), and steals (r = -0.52, p = 0.05). PCA proved effective in creating game competency scores, enabling a graphical representation of game-related performance. Conclusion: Findings suggest that trunk endurance alone was not directly related to game-related performance, while dynamic balance metrics showed moderate correlations. The PE values provide deeper insights into the balance-trunk stability relation. The dynamic balance test could support player monitoring, and the PCA based method facilitates player profiling.

Nonlinear metrics such as entropy and fractal dimension enhance understanding of gait stability beyond traditional measures, thus improving diagnostic and physical therapy assessments. Entropy metrics measure the regularity of time-series data as a number between 0 and 2, with lower values signifying a more regular series. Fractal dimension quantifies the complexity and self-similarity of time-series data.This study aimed to determine which input variable values influence approximate entropy (ApEn), sample entropy (SampEn), and Higuchi’s fractal dimension (HFD) parameters’ effectiveness for evaluating the stability of various individuals.

Funding: This work was supported by JSPS KAKENHI Grant Number 21K17600. AB - We examined the effects of side-dominance on the laterality of standing stability using ground reaction force, motion capture ( MoCap ), and EMG data in healthy young adults. We recruited participants with strong right ( n = 15) and left ( n = 9) hand and leg dominance (side-dominance). They stood on one or two legs on a pair of synchronized force platforms for 50 s with 60 s rest between three randomized stance trials. In addition to 23 CoP -related variables, we also computed six MoCap variables representing each lower-limb joint motion time series. Moreover, 39 time- and frequency-domain features of EMG data from five muscles in three muscle groups were analyzed. Data from the multitude of biosignals converged and revealed concordant patterns: no differences occurred between left- and right-side dominant participants in kinetic, kinematic, or EMG outcomes during bipedal stance. Regarding single leg stance, larger knee but lower ankle joint kinematic values appeared in left vs right-sided participants during non-dominant stance. Left-vs right-sided participants also had lower medial gastrocnemius EMG activation during non-dominant stance. While right-side dominant participants always produced larger values for kinematic data of ankle joint and medial gastrocnemius EMG activation during non-dominant vs dominant unilateral stance, this pattern was the opposite for left-sided participants, showing larger values when standing on their dominant vs non-dominant leg, i.e., participants had a more stable balance when standing on their right leg. Our results suggest that side-dominance affects biomechanical and neuromuscular control strategies during unilateral standing. LA - English DB - MTMT ER -
