Context: Foot structure has been shown to affect aspects of neuromuscular control, including postural stability and proprioception. However, despite an association between pronated supinated foot structures the incidence lateral ankle sprains, no one our knowledge measured muscle reaction time a simulated ankle-sprain mechanism in participants with different structures. Objective: To determine whether or contribute deficits as by mechanism. Design: Cross-sectional study. Setting: University...

Whilst previous research has highlighted significant relationships between golfers' clubhead velocity (CHV) and their vertical jump height maximum strength, these field-based protocols were unable to measure the actual ground reaction force (vGRF) variables that may correlate performance. The aim of this study was investigate isometric mid-thigh pull (IMTP), countermovement (CMJ), squat (SJ) drop (DJ) vGRF CHV in highly skilled golfers. Twenty-seven male category 1 golfers performed IMTP,...

A number of field-based investigations have evidenced practically significant relationships between clubhead velocity (CHV), vertical jump performance and maximum strength. Unfortunately, whilst these provide a great deal external validity, they are unable to ascertain ground reaction force (vGRF) variables that may relate golfers' CHVs. This investigation aimed assess if the variance in European Challenge Tour CHVs could be predicted by countermovement (CMJ) positive impulse (PI), isometric...

Cryotherapy is used widely in sport and exercise medicine to manage acute injuries facilitate rehabilitation. The analgesic effects of cryotherapy are well established; however, a potential caveat that cooling tissue negatively affects neuromuscular control through delayed muscle reaction time. This topic important investigate because athletes often return exercise, rehabilitation, or competitive activity immediately shortly after cryotherapy.To compare the wet-ice application, cold-water...

Hypertension and metabolic syndrome (METSYN) are reportedly high in police forces. This may contribute to health deterioration absenteeism personnel. Police forces comprise of staff ‘operational’ ‘non-operational’ job types but it is not known if type associated hypertension METSYN prevalence. study aimed explore the prevalence METSYN, factors with risk compare physiological, psychological, behavioural between operational non-operational Cross-sectional data was collected from 77 60 workers....

The aim of this study was to investigate the reliability fatigue indicators calculated from peak torque and total work during isokinetic speeds 60, 90, 120 180° · s⁻¹ a hip protocol. 10 males suffering history unilateral functional ankle instability male healthy controls performed 5 maximal concentric contractions on an dynamometer. Following 4 min rest period subjects were instructed perform repeated fatigue, which defined as 3 consecutive repetitions below 50% maximum value....

Ankle sprains result in pain and disability. While factors such as body mass prior injury contribute to subsequent injury, the association of number ankle on anthropometrics self-reported function are unclear this population. Therefore, purpose investigation was assess differences anthropometric measurements between utilizing a large, pooled data set.Cross-sectional.Data were from 14 studies (total N = 412) collected by Chronic Instability Outcomes Network. Participants categorized sprains....

Introduction: Research on athletic footwear familiarisation within an older population is sparse. This problematic because unfamiliar may act as a new perturbation and modify adults’ walking gait stability. In addition, while has been suggested to enhance comfort support during activities of daily living, the necessary period for with unknown. Therefore, this study aimed identify number steps required adults be familiarised different midsole thicknesses. Methods: Twenty-six healthy...

RELATIONSHIP BETWEEN ANTHROPOMETRIC CHARACTERISTICS OF INDOOR ROCK CLIMBERS AND TOP ROPED CLIMBING PERFORMANCE. Andrew C.S. Mitchell, Anjuna Bowhay and Joe Pitts. Biomechanics Research Group, University of Hertfordshire, Hatfield, United Kingdom. Historically, climbing was a sport dominated by males but in recent years the percentage female climbers at indoor facilities has risen to around 40%. Anthropometric comparisons between elite recreational have been carried out few studies compared...

Golf handicap is significantly correlated to putting performance with low golfers (LH) demonstrating increased accuracy compared high (HH). Smaller center of pressure excursion (CPE) during has been demonstrated by LH golfers, suggesting balance important successful putts. The aim this study was examine CPE in low, mid and about the mediolateral axis (ML) anteriorposterior (AP). Nineteen subjects participated study; were split into LH, HH groups. Subjects completed five 2.5m putts, standing...

This study aimed to examine the effect of impact point on golf ball horizontal launch angle and side spin during putting with a mechanical arm human participants. Putts 3.2 m were completed (four putter-ball combinations, total 160 trials) participants (two 337 trials). The centre dimple pattern (centroid) was located following variables measured: distance from centroid surface area zone. Multiple regression analysis conducted identify whether had significant associations roll variables,...

Abstract High amounts of sitting increase the risk non-communicable disease and mortality. Treadmill desks make it possible to reduce during desk-based workerʼs day. This study investigated acute effect on postural stability interrupting prolonged with an accumulated 2-h light-intensity treadmill desk walking. Twenty-one sedentary adults participated in this randomized crossover trial, two 6.5 h conditions: 1) uninterrupted 2) interrupted 2 Pre- post-condition, participants performed four...

This study aimed to examine the reliability of an experimental method identifying location impact point on a golf ball during putting. Forty trials were completed using mechanical putting robot set reproduce putt 3.2 m, with four different putter-ball combinations. After locating centre dimple pattern (centroid) following variables tested; distance from centroid, angle centroid and derived X, Y coordinates. Good excellent was demonstrated in all reflected very strong relative (ICC =...

Abstract Background Pain‐free bite force (PFBF) is a promising measure to evaluate function in temporomandibular disorders (TMDs), yet the reliability of unknown. Objectives Establish (1) within‐session test–retest PFBF healthy population for single and mean three trials supported unsupported sitting; (2) standard error measurement (SEM) minimal detectable change (MDC). Methods Thirty participants ( n = 15 female, [SD] age 34.4 [11.0] years) completed two sessions (30–60 min apart)...
