In spite of having large height and body mass, horses are cursorial animals with an extensive gait repertoire and considerable athletic abilities. The limbs have evolved so that the heavy musculature is confined to the proximal limbs while the distal limbs are light in weight with a single functional digit and long, lightweight tendons to move and support the distal joints. These adaptations reduce the moment of inertia and decrease the energy expended to protract and retract the limbs during locomotion. There is a division of labor between the forelimbs, which have a pillar-like construction specialized for weight bearing, and the hind limbs, in which the more angulated joints provide leverage for the generation of propulsion...

The aim of this study was to investigate the level of vision impairment (VI) that would reduce performance in shooting; to guide development of entry criteria to visually impaired (VI) shooting. Nineteen international-level shooters without VI took part in the study. Participants shot an air rifle, while standing, toward a regulation target placed at the end of a 10 m shooting range. Cambridge simulation glasses were used to simulate six different levels of VI. Visual acuity (VA) and contrast sensitivity (CS) were assessed along with shooting performance in each of seven conditions of simulated impairment and compared to that with habitual vision...

Evidence-based classification systems in Paralympic sport require knowledge of the underlying effect of impairment in a specific sport. This study investigated the relationship between cognition and tactical proficiency in 88 well-trained table tennis players with intellectual disability (ID; 29 women, 59 men, M ± SD IQ 59.9 ± 9.6). Data were collected at 3 competitions sanctioned by the International Federation for Para-Athletes with Intellectual Disabilities (INAS). A generic cognitive test consisting of 8 neuropsychological subtests was used to assess cognitive abilities relevant to sport (reaction time, processing speed, and decision speed; spatial visualization; fluid reasoning; memory; executive functioning; and visual processing)...

CONTEXT: While the incidence and re-injury rates of lateral ankle sprain (LAS) continue to persist at high rates across many sporting activities, further exploration of assessment and treatment beyond the traditional ligamentous and strength/proprioceptive model is warranted. Further, assessing and treating both arthrokinematic and osteokinematic changes associated with LAS can provide insight into a more diverse approach to treating ankle pathology. OBJECTIVE: To examine the clinical use of the Mulligan Concept MWM while treating patients diagnosed with an acute grade I or II LAS through authentic patient care...

Sounds offer a rich source of information about events taking place in our physical and social environment. However, outside the domains of speech and music, little is known about whether humans can recognize and act upon the intentions of another agent's actions detected through auditory information alone. In this study we assessed whether intention can be inferred from the sound an action makes, and in turn, whether this information can be used to prospectively guide movement. In 2 experiments experienced and novice basketball players had to virtually intercept an attacker by listening to audio recordings of that player's movements...

There is a large and growing body of surface electromyography (sEMG) research using laboratory-specific signal processing procedures (i.e., digital filter type and amplitude normalisation protocols) and data analyses methods (i.e., co-contraction algorithms) to acquire practically meaningful information from these data. As a result, the ability to compare sEMG results between studies is, and continues to be challenging. The aim of this study was to determine if digital filter type, amplitude normalisation method, and co-contraction algorithm could influence the practical or clinical interpretation of processed sEMG data...

Talent identification (TID) is a pertinent component of the sports sciences, affording practitioners the opportunity to target developmental interventions to a select few; optimising financial investments. However, TID is multi-componential, requiring the recognition of immediate and prospective performance. The measurement of athletic movement skill may afford practitioners insight into the latter component given its augmented relationship with functional sport specific qualities. It is currently unknown whether athletic movement skill is a discriminant quality in junior Australian football (AF)...

BACKGROUND: In recent years, athletes have ventured into ultra-endurance and adventure racing events, which tests their ability to race, navigate, and survive. These events often require race participants to carry some form of load, to bear equipment for navigation and survival purposes. Previous studies have reported specific alterations in biomechanics when running with load which potentially influence running performance and injury risk. We hypothesize that a biomechanically informed neuromuscular training program would optimize running mechanics during load carriage to a greater extent than a generic strength training program...

BACKGROUND: Although the relationship of self-efficacy to sports performance is well established, little attention has been paid to self-efficacy in the movements or actions that are required to perform daily activities and prepare the individual to resume sports participation following an injury and associated period of rehabilitation. There are no instruments to measure self-confidence in movement validated in an adolescent population. PURPOSE: The purpose of this paper is to report on the development of the AMCaMP, a self-report measure of confidence in movement and provide some initial evidence to support its use as a measure of confidence in movement...

BACKGROUND: Plantar fasciitis (PF) is the most common cause of heel pain that affects 10% of the general population, whether living an athletic or sedentary lifestyle. The most frequent mechanism of injury is an inflammatory response that is caused by repetitive micro trauma. Many techniques are available to diagnose PF, including the use of ultrasonography (US). PURPOSE: The purpose of this study is to systematically review and appraise previously published articles published between the years 2000 and 2015 that evaluated the effectiveness of using US in the process of diagnosing PF, as compared to alternative diagnostic methods...

BACKGROUND: Dizziness is often reported after a sports-related concussion. Forces experienced at the time of the concussion can cause an injury to multiple anatomical areas, including the central nervous system, the vestibular system, and the cervical spine, each of which is sufficient to cause dizziness. Medical professionals routinely use the subjective history to develop hypotheses about what may be causing a patient's dizziness. No previous studies have attempted to differentiate the source of the dizziness through precise patient descriptors or the triggers of dizziness...

The human mirror neuron system is believed to play an important role in facilitating the ability of athletes to anticipate the actions of an opponent. This system is often assessed with EEG by measuring event-related changes in mu (8-13Hz) sensorimotor oscillations. However, traditional channel-based analyses of this measure are flawed in that due to volume conduction effects mu and non-mu alpha activity can become mixed. This flaw means it is unclear the extent to which mu activity indexes the mirror system, as opposed to other processes such as attentional demand...

PURPOSE: Medial displacement calcaneal osteotomy with flexor digitorum longus transfer is a common treatment for the management of the adult flatfoot associated with posterior tibial tendon dysfunction. In the literature, there is a paucity of information regarding the ability of patients to return to sport and recreational activities after this surgical procedure. The purpose of this retrospective clinical study was to assess the rate and type of athletic activities that patients participated in before and after medial displacement calcaneal osteotomy with flexor digitorum longus transfer...

The aim of this study was to assess the visuo-oculomotor skills of gaze orientation in selected sport activities relative to visual demands of the sporting environment. Both temporal and spatial demands of the sporting environment were investigated: The latency and accuracy of horizontal saccades and the gain of the horizontal smooth pursuit of the sporting environment were investigated in 16 fencers, 19 tennis players, 12 gymnasts, 9 swimmers and 18 sedentary participants. For the saccade test, two sequences were tested: In the fixed sequence, participants knew in advance the time interval between each target, as well as the direction and the amplitude of its reappearance; in the Freyss sequence however, the spatial changes of the target (direction and amplitude) were known in advance by participants but the time interval between each target was unknown...
