INTRODUCTION Injury prevention is an essential aspect in the services athletic trainers can provide their patients. Strengthening muscles, improving balance and coordination, and increasing flexibility are all measurable outcomes that can be achieved by the athlete. Despite these efforts to prevent injury, assessing and predicting injury in athletic populations is not an easy task, as several variables need to be taken into account in order to obtain an accurate prediction. One such variable is the athlete’s reaction time, as it is incredibly important to all manner of athletes. These individuals often have to execute spur of the moment decisions to quickly avoid a defender, hit or catch a ball, and successfully react to additional visual, …show more content…
There were 125 subjects, 56 of which were men and 69 women. These 125 individuals participated in Phase I of the study. Phase I consisted assessments given by Nike Sensory Station. These assessments included Perception Span, Eye-Hand Coordination, Go/No Go, and Reaction Time. Each session was completed in about 20 minutes. Perception Span measured the speed and span of recognition and Eye-Hand Coordination measured reaction time. Go/No Go also measured reaction time while the Reaction Time assessment measured central eye-hand reaction and response time. After analysis and subject feedback, the researchers made modifications to the equipment, instructions and protocols in order to improve the reliability of the tests. In Phase II, 36 subjects (20 men, 16 women) who had not participated in Phase I were recruited. Phase II consisted of the same assessments used in Phase I. The results were analyzed primarily using ANOVA and Student’s-paired t-tests. Results exhibited no significant change in performance over time on assessments of Visual Clarity, Contrast Sensitivity, Depth Perception, Target Capture, Perception Span, and Reaction

    Bonnechere et al. support their claims through the observation of biomechanics. Data was gathered from twenty-five healthy young men, twelve of whom were football players. The other thirteen participants were non-players. Using some type of stereophotogrammetric system, motions and position parameters were recorded (Bonnechere, Beyer, Rooze, Serge Van Sint, 2014). Each of the men demonstrated the three different starting positions: two-point, three-point, and four-point position (Bonnechere et al., 2014). Trials were conducted three times to obtain accurate results. The data concluded that the four-point position had the most damaging potential due to the lack of visual capacity from the increased disability to reposition the head. Therefore, the greater the field of view (FOV), the less risk for…

    The purpose of this experiment was to examine the difference between slow and fast twitch muscle fibers between men and women. Based on the definitions of slow and fast twitch muscle fibers, and given the fact that previous studies state that testosterone increases fast twitch muscle fibers, we expect that athletic men will have a higher leap because they have more fast twitch muscle fibers.…

    Various modifiable risk factors have been reported by different authors, with varying levels of evidence and often conflicting, including athlete weight, playing position, quadriceps peak torque, quadriceps flexibility, hip flexor flexibility, lower limb strength asymmetry and hamstring/quadriceps to hamstring ratio (Beijsterveldt, 2013; Chalmers, 2013; Freckleton, 2013). Of these modifiable risk factors, the quadriceps peak torque has shown as strong association with the future incidence of RHI (Tol et al, 2014). Even so, it is difficult to evaluate the quadriceps peak torque in a real soccer environment because: I) it does not reflect the biomechanical aspect where the hamstring injury is most predisposed to strain in sprinting and II) most soccer clubs do not have access to isokinetic testing equipment (Brughelli et al, 2011). Next, other modifiable factors such as hip flexors flexibility and hamstring to opposite hamstring strength symmetry (Schache, 2011), showed some evidence but inadequate the study power or could not be analyzed (mostly due to the rigorous methodology warranted in such evaluation) in a meta-analysis to strongly verify their relationship to RHI. Overall, a common barrier in interpreting the clinical significance of these…

    ABA measures behavior in obtaining the significance of whether it is necessary to determine an individual needs treatment. If so, what treatment is appropriate, as well as if the treatment is working for the target behavior. Also, measuring behaviors can be determined by three fundamental properties comprise of repeatability, temporal extent, and temporal locus. (Cooper, et al., 2014). In assessing the quality of measurement indicators of the attribute of data incorporate interobserver agreement. Which are at least two independent observers reporting the same observed values in the wake of measuring similar events (Cooper, et al., 2014). Accuracy, the degree to which observed values, information, coordinate the genuine condition of the event…

    When I conduct my first observation, I was amazed to a young lady who sings reflection. She really sang it beautifully. During their past time they always did it, someone sing, dance, and doing some art. When the demo teacher arrives, they start to keep what they are doing and listen to what the teacher is saying. The teacher designed the activities into a game so that they will gain the attention of the learner. And most of the activities require the body to move and not just sitting down on their chair. In the transition class, most of the lesson that are taught are more on daily living skills for them to survive.…

    The evaluation of an object without the visual concept can be difficult for some people, since they experience the internal process where frustration, anxiety and boredom are a barrier from concentration. The assignment that we did consisted in bringing to class an unfamiliar object in a bag so anyone could see it in order to describe the object in details without the visual concept. We exchange the object with someone else who did not know what the object was. My partner gave me her object inside her glasses case; so I decide to close my eyes and try to describe the case also as part of this assignment since I did not see it in details.…

    Repeated Measures Analysis of Variance (RM-ANOVA) was conducted to compare the reaction time of visual and acoustic conditions (previously shown in study phase) with new brands (not presented before)(Graph 1). Mauchly’s test showed that the assumption of sphericity had not been violated, χ2 (2) = 0.68, p = .711. Degrees of freedom were corrected using Greenhouse-Geisser estimates of sphericity ( = .98). There was a significant effect of modality type, F (2, 60) = 20.09, p < .001. Bonferroni Post-hoc tests displayed significant effect for visual versus acoustic; the visual brands were faster than acoustic (p < .001). On the other hand, Mixed ANOVA used to compare the performance of gender and it showed that there was not a significant effect…

    Warming up before a game or an event has become such an important and common task that researchers have been continuously trying to find ways to improve performance through warming up. Researchers are still trying to figure out whether a 20-30 minute moderate intensity warm up is enough to reach someone’s optimal sprint performance. Many studies have found that the most influential factors that warm-ups have on sprint performance include the increase of muscle temperature (Faulkner, Ferguson, Hodder, & Havenith, 2013 & Zois, Bishop, Ball, & Aughey, 2011 & Sander, Keiner, Schlumberger, Wirth, & Schmidtbleicher, 2013 & Mohr, Krustrup, Nybo, Nielsen, & Bangsbo, 2003). This leads to the second part of the study to find out if…
