The purpose of this systematic review was to investigate the weight of scientific evidence regarding student outcomes (physical, cognitive and affective) of a Game Centered Approach (GCA) when the quality of a study was taken into account in the interpretation of collective findings. A systematic search of five electronic databases (Sports Discuss, ERIC, A+ Education, PsychInfo and PROQUEST Education) was conducted from their year of inception to 30 January 2014. Included studies were longitudinal or experimental/quasi-experimental studies involving children or adolescents that quantitatively assessed (using repeat measures and/or comparison with a control group) the effects upon student outcomes when an intervention involved the use of a GCA. The search identified 15 articles examining the effects of GCA on student outcomes that met the criteria for inclusion. The weight of evidence provided by the included studies identified an association between a GCA and the outcomes of declarative knowledge, support during game play and affective outcomes of perceived competence, interest/enjoyment and effort/importance. Development of technical skill, procedural knowledge and game play skills of decision making and skill execution are not supported by the level of evidence currently provided. Intervention volume appears to have a large effect on the development of game based decision making and skill execution, with a positive association between these outcomes and use of GCA interventions greater than eight hours in volume. More longitudinal and intervention research examining the use of a GCA and potential psychological, physiological and behavioral outcomes in children and adolescents is recommended.

Context: Quantification of the magnitudes of fluid resistance provided by water jets (currents) and their effect on energy expenditure during aquatic-treadmill walking is lacking in the scientific literature. Objective: To quantify the effect of water-jet intensity on jet velocity, drag force, and oxygen uptake (VO2) during aquatic-treadmill walking. Design: Descriptive and repeated measures. Setting: Athletic training facility. Participants, Interventions, and Measures: Water-jet velocities were measured using an electromagnetic flow meter at 9 different jet intensities (0-80% maximum). Drag forces on 3 healthy subjects with a range of frontal areas (600, 880, and 1250 cm2) were measured at each jet intensity with a force transducer and line attached to the subject, who was suspended in water. Five healthy participants (age 37.2 ± 11.3 y, weight 611 ± 96 N) subsequently walked (~1.03 m/s or 2.3 miles/h) on an aquatic treadmill at the 9 different jet intensities while expired gases were collected to estimate VO2. Results: For the range of jet intensities, water-jet velocities and drag forces were 0-1.2 m/s and 0-47 N, respectively. VO2 increased nonlinearly, with values ranging from 11.4 ± 1.0 to 22.2 ± 3.8 mL × kg-1 × min-1 for 0-80% of jet maximum, respectively. Conclusions: This study presented methodology for quantifying water-jet flow velocities and drag forces in an aquatic-treadmill environment and examined how different jet intensities influenced VO2 during walking. Quantification of these variables provides a fundamental understanding of aquatic-jet use and its effect on VO2. In practice, these results indicate that VO2 may be substantially increased on an aquatic treadmill while maintaining a relatively slow walking speed.

In today’s challenging economic climate at most universities, kinesiology administrators are becoming increasingly aware of the need to participate in activities that will generate alternative revenue sources related to their academic mission. The ways deans and development officers communicate with alumni, potential donors, upper administrative leaders, and legislatures will all impact how successful the efforts to develop funds and partnerships will be. Successful fundraisers are those who can generate strategic alliances, create and market a plan that relates needs to societal issues of public interest and university priorities, and are able to identify partnerships that will produce an increase in resources. This paper provides strategies for identifying and connecting with key donors, building partnerships, developing the plan and cultivating internal and external audiences, aligning needs with university priorities, and working with legislatures.

When reporting a subject’s mean movement pattern, it is important to ensure that reported values are representative of the subject’s typical movement. While previous studies have used the mean of 3 trials, scientific justification of this number is lacking. One approach is to determine statistically how many trials are required to achieve a representative mean. This study compared 4 methods of calculating the number of trials required in a hopping movement to achieve a representative mean. Fifteen males completed 15 trials of a lateral hurdle hop. Range of motion at the trunk, pelvis, hip, knee, and ankle, in addition to peak moments for the latter 3 joints were examined. The number of trials required was computed using a peak intraclass correlation coefficient method, sequential analysis with a bandwidth of acceptable variance in the mean, and a novel method based on the standard error of measurement (SEMind). The number of trials required across all variables ranged from 2 to 12 depending on method, joint, and anatomical plane. The authors advocate the SEMind method as it demonstrated fewer limitations than the other methods. Using the SEMind, the required number of trials for a representative mean during the lateral hurdle hop is 6.

Chronic athletic groin pain (AGP) is common in field sports and has been associated with abnormal movement control and loading of the hip and pelvis during play. A single-leg squat (SLS) is commonly used by clinicians to assess movement control, but whether it can provide insight into control during more dynamic sporting movements in AGP patients is unclear.
To determine the relationships between biomechanical measures in an SLS and the same measures in a single-leg drop landing, single-leg hurdle hop, and a cutting maneuver in AGP patients.
40 recreational field-sports players diagnosed with AGP.
A biomechanical analysis of each individual’s SLS, drop landing, hurdle hop, and cut was undertaken.
Main Outcome Measures:
Hip, knee, and pelvis angular displacement and hip and knee peak moments. Pearson product–moment correlations were used to examine relationships between SLS measures and equivalent measures in the other movements.
There were no significant correlations between any hip or pelvis measure in the SLS with the same measures in the drop landing, hurdle hop, or cut (r = .03–.43, P > .05). Knee frontal- and transverse-plane angular displacement were related in the SLS and drop landing only, while knee moments were related in the SLS, drop-landing, and hurdle hop (r = .50–.67, P < .05).
For AGP patients, an SLS did not provide meaningful insight into hip and pelvis control or loading during sporting movements that are associated with injury development. The usefulness of an SLS test in the assessment of movement control and loading in AGP patients is thus limited. The SLS provided moderate insight into knee control while landing and therefore may be of use in the examination of knee-injury risk.

A 22-year-old male varsity collegiate wrestler presented for general chiropractic care for an unrelated condition and noted right elbow pain that had progressively increased over the past few weeks. The athlete was diagnosed with a right brachialis strain and advised to follow up with his athletic trainer for co-management of his injury. The patient responded positively to prescribed treatments and rehabilitation to decrease pain and restore functionality (<14 days) while only missing one competitive match. The location of the brachialis muscle and scarcity of literature makes diagnosis and treatment complex. The physical examination and conservative treatment presented in this report demonstrate the need for comprehensive and exploratory examination and co-management of wrestling athletes with a brachialis strain.

Recent international conference presentations have critiqued the promotion of fundamental movement skills (FMS) as a primary pedagogical focus. Presenters have called for a debate about the importance of, and rationale for teaching FMS, and this letter is a response to that call. The authors of this letter are academics who actively engage in FMS research.
We have answered a series of contentions about the promotion of FMS using the peer reviewed literature to support our perspective.
We define what we mean by FMS, discuss the context of what skills can be considered fundamental, discuss how the development of these skills is related to broader developmental health contexts, and recommend the use of different pedagogical approaches when teaching FMS.
We conclude the promotion of FMS is an important focus in Physical Education (PE) and sport and provide future research questions for investigation.
