The Assessment Of Swimming And Survival Skills: Is Your Programme Fit For Its Purpose?, Paolo Di Paola Aug 2019

The Assessment Of Swimming And Survival Skills: Is Your Programme Fit For Its Purpose?, Paolo Di Paola

International Journal of Aquatic Research and Education

Assessment of swimming and survival skills is a crucial part of any swimming and lifesaving programme. Unfortunately, quite often, it is also the weakest part of the programme itself. Inadequate skills assessment and verification might lead to ineffective skills acquisition and development, to a false sense of safety and over confidence in the water that can be extremely dangerous. Assessor experience and observation skills, assessment methodology, and criteria are all closely inter-linked and their interaction will somehow determine the assessment outcomes. Our paper analyses some of the current issues in these areas of the assessment process, such as assessor’s lack …

The goal of this study was to determine if there is a relationship between ocular dominance and visual processing under a variety of computer gaming tasks. This was accomplished by first determining subjects’ ocular dominance through the Miles test, and then examining the subjects’ visual performance on four different Lumosity games under three conditions: left eye, right eye, and both eyes. Results suggest a relationship …


Revised Scientific Review: Minimum Age For Swim Lessons, Stephen J. Langendorfer Ph.D. Jan 2019

Revised Scientific Review: Minimum Age For Swim Lessons, Stephen J. Langendorfer Ph.D.

International Journal of Aquatic Research and Education

The question addressed in the original scientific review (2009) was rephrased as Does sufficient scientific evidence exist to support setting a minimum age for swimming lessons? for this triennial review. Addressing the research question is significant because strong differences of opinion about the appropriate age(s) for initiating learn-to-swim lessons have existed among the pediatric medical profession, aquatic professionals and agencies, and proprietary programs and swim schools for over four decades. The question has implications for the appropriate purposes, pedagogies, and outcomes associated with swimming experiences for infants and young children that will be addressed in a subsequent review. The revised …

Clinician-Administered Versus Self-Administered Suboccipital Release On Superficial Backline Function, Colin Wilhite, Kristin A. Paloncy, Karen Rawkowski, Todd Daniel

Clinical Practice in Athletic Training

The effectiveness of trigger point release in the suboccipital region to improve hamstring mobility has been established in the literature, but the research has not clarified whether self-administered soft tissue techniques produce the same improvements to mobility as when the clinician delivers the manual trigger point release. The purpose of the study was to assess whether the same increase in hamstring mobility within the superficial backline function that is achieved with a clinician-administered suboccipital trigger point release can also be obtained through a patient/self-administered method. The study employed a randomized, descriptive laboratory design in which 60 participants reported for a …

Best Practices In Patellar Tendinopathy Management: An Evidence To Practice Review, Christopher J. Burcal, Adam B. Rosen, Tony Taylor, Mike Nicola

Clinical Practice in Athletic Training

Patellar tendinopathy (PT) is a degenerative condition that is common in sporting populations due to the loads placed on the tendon during dynamic activity. PT often occurs in overtraining situations; however, it may also occur in conjunction with and/or worsen through poor biomechanics, persistent inflammation, and altered movement patterns. Although sports medicine practitioners have evidence to support the prevalence of this injury, we do not have a strong base of evidence surrounding the contributing factors and pathophysiology that lead the pain and disability reported in patients with PT. The purpose of this evidence to practice review was to summarize a …

The purpose of the disablement model case study was to describe the case of a collegiate basketball player suffering from anterior knee pain (AKP). The patient had been experiencing AKP while participating in pre-season basketball related activities (playing, weight lifting, and conditioning) for approximately six weeks. As the intensity increased, the pain became intolerable. Previously, the patient had missed a significant amount of off-season workouts due to surgery for an upper extremity injury sustained during the competitive season. The patient reported tenderness at the inferior pole of the patella, and at the tibial tuberosity. There was no joint line tenderness, …


Regionally Interdependent Applications Of Total Motion Release® And Active Rotational Shoulder Range Of Motion In Overhead Athletes, R. Ross Dexter, Terylan K. Loftis, Russell T. Baker, Timothy E. Speicher Jan 2019

Regionally Interdependent Applications Of Total Motion Release® And Active Rotational Shoulder Range Of Motion In Overhead Athletes, R. Ross Dexter, Terylan K. Loftis, Russell T. Baker, Timothy E. Speicher

Clinical Practice in Athletic Training

Healthy athletes commonly engage in pre-participation warm-up strategies designed to physiologically and mechanically prepare the body for training and competition. Alterations in rotational range of motion (ROM) of the dominant shoulder in overhead athletes, resulting in total rotation ROM loss, correlate with performance deficit, injury risk, and lost training time. Researchers have suggested that interventions using Total Motion Release® (TMR®) increase shoulder ROM more effectively than traditional warm-up methods. A randomized pre-test post-test trial was used to explore the effects of a regionally interdependent application of TMR® via a forward flexed trunk twist (FFTT) and seated straight leg raise (SLR) …
