Related Data for: Biomechanics of step-off drop landings are affected by limb dominance and lead limb in task initiation
No full textThis study examines the effects of limb dominance and lead limb in task initiation on the kinetics and kinematics of step-off drop landings. Nineteen male participants performed drop landings led by the dominant and non-dominant limbs at 45-cm and 60-cm drop heights. Ground reaction force (GRF) and lower body kinematic data were collected. Between-limb time differences at the initial ground contact were calculated to indicate temporal asymmetry. Statistical Parametric Mapping (SPM) was applied for waveform analysis while two-way repeated measures ANOVA was used for discrete parameters. SPM results revealed greater GRF and lesser ankle dorsiflexion in the lead limb compared to the trail limb in 3 out of 4 landing conditions. The dominant limb displayed a greater forefoot loading rate (45 cm: p=.009, ηp2 = 0.438; 60 cm: p=.035, ηp2 = 0.225) and greater ankle joint quasi-stiffness (45 cm: p < .001, ηp2 = 0.360; 60 cm: p < .001, ηp2 = 0.597) than the non-dominant limb. Not all 380 trials were lead-limb first landings, with a smaller between-limb time difference (p=.009, d = 0.60) at 60 cm (4.1 ± 2.3 ms) than 45 cm (5.6 ± 2.7 ms). In conclusion, the step-off drop landing is not an ideal protocol for examining bilateral asymmetry in lower limb biomechanics due to potential biases introduced by limb dominance and the step-off limb
Related Data for: Influence of shoe midsole hardness on plantar pressure distribution in four basketball-related movements
No full textThis study examined how shoe midsole hardness influenced plantar pressure in basketball-related movements. Twenty male university basketball players wore customized shoes with hard and soft midsoles (60 and 50 Shore C) to perform four movements: running, maximal forward sprinting, maximal 45° cutting and layup. Plantar loading was recorded using an in-shoe pressure measuring system, with peak pressure (PP) and pressure time integral (PTI) extracted from 10 plantar regions. Compared with hard shoes, subjects exhibited lower PP in one or more plantar regions when wearing the soft shoes across all tested movements (Ps < 0.05). Lower PTI was also observed in the hallux for 45° cutting, and the toes and forefoot regions during the first step of lay-up in the soft shoe condition (Ps < 0.05). In conclusion, using a softer midsole in the forefoot region may be a plausible remedy to reduce the high plantar loading experienced by basketball players
Leadership styles, school effective, needs of 'mien' (face) behaviour: the interactions in Hong Kong private schools
No full textNational cultures vary and the variations challenge the conventional wisdom of the Western management theory and practice in other cultural contexts. Specifically, the national characteristic of 'face(mien) behaviour' is immensely important at all levels in Chinese interpersonal communications. The notion of 'mien' permeates every aspect of interpersonal relationships in Chinese culture because of the culture’s overarching concern with relationships. This study examines the nature of 'mien' behaviour, explores how 'mien' functions in the Hong Kong educational context, and how leadership styles of secondary school principals interact with 'mien' as perceived by their teaching staff and how, eventually, these interactions influence the effectiveness of the schools. Whenever Chinese behaviour is discussed, the social philosophy of Confucianism is relevant. The Confucian ethical system regulating social behaviour has three principle ideas: ren(), yi() and li(); benevolence, righteousness or justice, and propriety or courtesy. This study also examines how these three principles nurture 'mien' and considers whether any alternate style of leadership in Hong Kong context can be formulated

Related Data for: In-shoe plantar pressure profiles in amateur basketball players – Implications for footwear recommendation and orthoses use
No full textBackground: Biomechanical analysis of foot loading characteristics may provide insights into the injury mechanisms and guide orthotic prescription for basketball players. This study aimed to quantify in-shoe plantar pressure profiles in amateur players when executing typical basketball movements.
Methods: Twenty male university basketball players performed four basketball-specific movement tasks—running, maximal forward sprinting, maximal 45° cutting, and layup—in a pair of standardized basketball shoes fitted with an in-shoe plantar pressure measurement system. Peak pressure (PP) and pressure-time integral (PTI) data were extracted from ten plantar regions. One-way repeated-measures analysis of variance was performed across the tasks, with significance set at P
Results: Distinct plantar pressure distribution patterns were observed among the four movements. Compared with running, significantly higher (P
Conclusions: Compared with running, sprinting and layup demonstrated higher plantar loading in the forefoot region, and 45° cutting yielded increased plantar loading in most regions of the foot. Understanding the plantar pressure characteristics of different movements may be useful in optimizing footwear designs, orthosis use, or training strategies to minimize regional plantar loading during amateur basketball play.</p
Related Data for: Center of pressure and perceived stability in basketball shoes with soft and hard midsoles
No full textThis study aimed to investigate the effects of varying midsole hardness on center of pressure (COP) and perceived stability during basketball-specific tasks, as well as the correlation between COP and perception measurements. A total of 20 male basketball players performed 45° cutting and layup while wearing basketball shoes with soft and hard midsoles. COP trajectories were obtained from the Pedar insole system. Stability perceptions at the forefoot and rearfoot were assessed using 150-mm visual analogue scales. Results indicated greater COP mediolateral deviations in soft midsole compared with hard midsole during layup (soft: 16.6 [4.7] mm, hard: 15.8 [4.6] mm, P = .03) but not 45° cutting (soft: 15.7 [5.9] mm, hard: 15.8 [5.6] mm, P = .60). While 16 out of 20 participants preferred soft midsole, no significant difference in visual analogue scale ratings was found between shoes for both tested movements. There was no significant correlation between COP and perceived stability during layup or 45° cutting. In conclusion, midsole hardness of basketball shoes did not consistently affect mediolateral stability of the foot during 45° cutting and layup. Subjective perception alone cannot be used to indicate mediolateral deviation of the foot when executing basketball-specific maneuvers

Dental fear and anxiety among kindergarten children in Hong Kong
No full textBackground: The factors associated with dental fear and anxiety (DFA) in children are known to be complex. DFA is a major issue affecting children’s oral health and dental service providers.
Objectives: To describe the prevalence of DFA of kindergarten children in Hong Kong; and to investigate the associated factors with children’s dental fear.
Method: Parents of children aged 4 to 5 were recruited from 5 kindergartens in Hong Kong between January and March 2022. Parents completed a questionnaire on family demographic background, parent's and child's dental histories, and parental proxy of 15-item Children's Fear Survey Schedule-Dental Subscale (CFSS-DS). Children's DFA level was determined by the parent-reported CFSS-DS. Bivariate analysis using Chi-square test and multiple logistic regression was conducted to identify the association of parental and children characteristics with children's DFA level.
Results: Among the 153 children studied, DFA was present in 34.6% of children (CFSS-DS scored at least 38). The mean CFSS-DS score was 35.5 (SD = 11.0). Children with systemic conditions had a higher chance of having DFA (OR = 9.83; 95% CI: 1.11 – 86.85; p = 0.040) compared to their counterparts without systemic conditions. Children with parents that were fairly or very afraid of going to the dentist had a higher chance of having DFA (OR = 2.54; 95% CI: 1.12 – 5.76; p = 0.025) compared to children with parents that were not afraid or slightly afraid of the dentist.
Conclusion: Approximately one-third of Hong Kong kindergarten children were found to have DFA. The study also revealed that presence of parental dental fear and children’s systemic conditions are significantly associated with DFA in kindergarten children.published_or_final_versio
