Is there a sweet spot on the foot in Australian football drop punt kicking?

In the collision between a striking implement and ball, the term “sweet spot” represents the impact location producing best results. In football kicking, it is not known if a sweet spot exists on the foot because no method to measure impact location in three-dimensional space exists. Therefore, the aims were: (1) develop a method to measure impact location on the foot in three-dimensional space; (2) determine if players impacted the ball with a particular location; (3) determine the relationship between impact location with kick performance; (4) discuss if a sweet spot exists on the foot. An intra-individual analysis was performed on foot-ball impact characteristics of ten players performing 30 Australian football drop punt kicks toward a target. (1) A method to measure impact location was developed and validated. (2) The impact locations were normally distributed, evidenced by non-significant results of the Shapiro-Wilk test (p > 0.05) and inspection of histograms, meaning players targeted a location on their foot. (3) Impact location influenced foot-ball energy transfer, ball flight trajectory and ankle plantar/dorsal flexion. (4) These results indicate a sweet spot exists on the foot for the Australian football drop punt kick. In conclusion, the impact location is an important impact characteristic.     

Factors associated with minimal changes in countermovement jump performance throughout a competitive division I collegiate basketball season

ABSTRACT

The purpose of the study was to assess factors that contribute to countermovement jump (CMJ) performance in women’s basketball athletes. Thirteen female athletes participated and were tested for maximal oxygen uptake (VO_2max) and heart rate (HR_max). Athletes were monitored, daily for a total of 21 weeks with heart rate-based wearable devices and CMJ performance and body weight were tested weekly after one day of recovery. 3-jump average height (CMJ_avg), maximum height jump (CMJ_max), and CMJ power (Watts) were calculated and recorded. Playing intensities >85% HR_max, HR_avg, HR_max and training load were averaged for three consecutive days prior to the recovery day. After the season, data was grouped as changes in CMJ power from week one: Large (≤ ?4.39% change), Moderate (?4.4% to ?0.62% change), and Minimal (≥ ?0.61% change) changes. Fixed-effects models revealed a main effect of group (p ≤ 0.05) for CMJ_avg, CMJ_max, VO_2max, weekly percent changes in body weight and for 3-day training load, HR_avg, and playing time at >85% HR_max. When athletes experienced minimal changes in CMJ performance, relative to large changes, they produced greater power, jumped higher, avoided negative changes in weekly body weight, had a greater preseason VO_2max and 3-day average workloads appeared to have an impact on CMJ performance     

A Service-Learning Collaboration: A Graduate Gerontology Program and a Foster Grandparent Program

ABSTRACT

Historically, American institutions of higher learning have embraced community service as a necessary component of students' learning experiences. Recent initiatives through the Corporation for National and Community Service emphasize the idea that civic responsibility is an important element of an adequate education at all levels of learning. In this article we discuss the feasibility of integrating a graduate gerontology program and a Foster Grandparent Program. The integration is designed in such a way that, beyond sustaining the Foster Grandparent Program and introducing students to practical field experiences, greater community needs can be met. Ideally, positive outcomes will be achieved through such a collaborative effort, and will affect change at the individual, community, policy, and social structural levels.     

Welfare economics and public subsidies to the Arts

An Evaluation of the Progress,Experience and Employability of Mature Students on the BEd Course at Westminster College,Oxford

There are many adults who left school without A levels who wish to further their education as mature students. Because many of these adults are being accepted by colleges without traditional A levels, and with very few GCSE/O level subject passes, it has been suggested that their acceptance as students may lower the standard of the college courses. This paper evaluates the qualities which mature and non‐traditional entry students bring to college courses, and concludes that their results compare favourably with those of traditional entry students. Many mature students appear to have needs in common with other students and meeting these needs would result in better practice within institutions of higher education (HE). However, mature students also have specific needs which are evaluated in this paper. Most require little additional expenditure, but are rather a matter of will and organisation on the part of the institution and tutors. Entry as mature students onto BEd courses seems to be particularly attractive to women but some of them experience difficulty in finding employment. The data collected demonstrate that maturity is likely to be a positive attribute and the mature applicant for a post to be a ‘quality product’.
