Human gait is mainly related to the foot and leg movements but, obviously, the entire motor system of the human body is involved. We hypothesise that movement parameters such as dynamic balance, movement harmony of each body element (arms, head, thorax…) could enable us to finely characterise gait singularities to pinpoint potential diseases or abnormalities in advance. Since this paper deals with the preliminary problem pertaining to the classification of normal and abnormal gait, our study will revolve around the lower part of the body...

PURPOSE: The King-Devick test (KD) has been studied as a remove-from-play sideline test in college-age athletes and older; however, studies in younger athletes are limited. A cross-sectional study of the KD and other vision correlates was completed on school-aged athletes during pre-season physicals for a variety of sports to determine the repeatability of the KD. The study also evaluated how convergence, alignment, or pupil function contributed to a slower King-Devick baseline reading...

Human action recognition in videos is a topic of active research in computer vision. Dense trajectory (DT) features were shown to be efficient for representing videos in state-of-the-art approaches. In this paper, we present a more effective approach of video representation using improved salient dense trajectories: first, detecting the motion salient region and extracting the dense trajectories by tracking interest points in each spatial scale separately and then refining the dense trajectories via the analysis of the motion saliency...

Despite the call to improve health promotion (HP) in sport clubs in the existing literature, little is known about sport clubs' organizational capacity. Grounded within the setting-based framework, this study compares HP activities and guidance among 10 football clubs. At least three grassroots coaches from each club (n = 68) completed the Health Promoting Sports Clubs scale to assess their perceptions of HP; an official (n = 10) was interviewed about club's activities and official's guidance provided to coaches...

Binocular vision is the most important visual cue for spatial orientation in many sports. In this study, we investigated how binocular vision was influenced by an eye training program that may be used to improve individual's oculomotor function. The experiment involved twenty-four female student athletes from team ball sports (soccer, basketball, handball). After an initial testing session, 12 participants were randomly allocated to the experimental group. Optometric investigation which included synoptophore testing and a test of dissociated horizontal phoria based on the Maddox method was performed three times: before the experiment, after eight weeks of eye training (3 times a week for 20 minutes), and four weeks after the experiment was terminated...

BACKGROUND: Paralympic sports are required to develop evidence-based systems that allocate athletes into 'classes' on the basis of the impact of their impairment on sport performance. However, sports for athletes with vision impairment (VI) classify athletes solely based on the WHO criteria for low vision and blindness. One key barrier to evidence-based classification is the absence of guidance on how to address classification issues unique to VI sport. The aim of this study was to reach expert consensus on how issues specific to VI sport should be addressed in evidence-based classification...

Several previous studies have shown that floorball belongs to a high-risk group of sports in terms of eye injuries. Protective eyewear is available, but the extent of its use and impact on eye injuries are unknown. The purpose of this study was to investigate the current incidence of eye injuries caused by floorball and to compare it with the present use of protective eyewear. Medical records were used to identify all eye injuries suffered while playing floorball in Jönköping County from 2008 to 2011 (N = 167)...

Lipid disorders, obesity and overweight are considered one of the most important modifiable cardiovascular risk factors. Population surveys carried out in Poland have demonstrated a tendency for lipid disorders to occur in 70% and overweight and obesity in more than half of Poles. No such studies have been conducted in groups of people with vision impairment so far. Yet, regular involvement of visually impaired people in sports is likely to reduce cardiovascular risk. Therefore, the authors attempted to evaluate the lipid profile and nutritional status of male goalball players...

PURPOSE: This paper explores the conceptual content of Paralympism. It exists by exploring the nascent normative framework that the International Paralympic Committee (IPC) has begun to construct around its constituent sports. The IPC sets out four values: Courage, Determination, Inspiration and Equality. METHOD: Drawing on philosophical ethical methods it offers a critical evaluation of the four values that comprise the IPC position. CONCLUSION: While courage is undoubtedly a moral virtue, there is more than one conception that might inform Paralympism with either/both active and passive content...

Traumatic optic neuropathy is a rare cause of visual disturbance after head injury that can be difficult to distinguish from coexisting vestibulo-ocular dysfunction because of the overlap in presenting symptoms in patients with these conditions. We present a case report of a 13-year-old girl who sustained a head injury during a ringette game leading to blurred vision and diplopia persisting 5 months after injury. Clinical history and physical examination findings were consistent with a traumatic optic neuropathy, convergence insufficiency, and postconcussion syndrome...

Balance control improvement is one of the most important goals in sports and exercise. Better balance is strongly positively associated with enhanced athletic performance and negatively associated with lower limb sports injuries. Proprioception plays an essential role in balance control, and ankle proprioception is arguably the most important. This paper reviews ankle proprioception and explores synergies with balance control, specifically in a sporting context. Central processing of ankle proprioceptive information, along with other sensory information, enables integration for balance control...
