environment and policy that determine food availability ( Symmank et al., 2017 ). We previously reported on an expert review of the food provision for the London 2012 Olympic Games and found that there was limited choice of lower energy, low fat, and gluten-free items to meet the needs of athletes, as well as

Background:

The City of Vancouver, British Columbia strategically designed and implemented a municipal health promotion policy—the Vancouver Active Communities policy—to leverage the 2010 Olympic Games. The goal of the policy was to increase physical activity participation among Vancouver residents by 2010.

Methods:

In this paper, we conduct a critical policy analysis of health promotion policy documents that were available on the City of Vancouver’s website.

Results:

We elaborate on the background to the policy and more specifically we examine its content: the problem definition, policy goals, and policy instruments.

Discussion:

Our analysis showed inconsistency within the policy, particularly because the implemented policy instruments were not designed to address needs of the identified target populations in need of health promotion efforts, which were used to legitimize the approval of funding for the policy. Inconsistency across municipal policies, especially in terms of promoting physical activity among low-income residents, was also problematic.

Conclusions:

If other municipalities seek to leverage health promotion funding related to hosting sport mega-events, the programs and services should be designed to benefit the target populations used to justify the funding. Furthermore, municipalities should clearly indicate how funding will be maintained beyond the life expectancy of the mega-event.

By referring to criteria established by the International Olympic Committee (IOC) for including sports in the Olympic Games and considering the maturation of the sports movement for the disabled, it is reasonable to conclude that certain sports reserved exclusively for the disabled can be made eligible for inclusion in the Olympic Games as medal events. A confounding factor in pursuit of inclusion in the Olympic Games is the uncritical willingness of the established international sports organizations for the disabled to amalgamate in order to communicate as a single voice with the IOC. Created in the process is a formal institutionalization of sports programs for the disabled. Despite invitations to stage demonstration events in recent Olympic Games, sports organizations have failed to take measures necessary to qualify for full integration into the Olympic movement. Reorganization is called for on the basis of versions of sports that would lend themselves to integration.

Athletes report frequent use of various dietary supplements (DSs). However, no study has examined DS use and antidoping knowledge in Korean Olympians. The objectives of this study were to obtain information about Korean Olympians’ DS use during the training period for the Beijing 2008 Summer Olympic Games and immediately before their Olympic events, to obtain DS-intake reasons and DS providers, and to obtain information on athletes’ doping education, knowledge, and educators. Korean Olympians completed 2 questionnaires 1 wk before the opening and within 1 wk after the closing of the Beijing 2008 Summer Olympic Games. Results showed that 79% of male and 82% of female Olympians take more than 1 DS during the training period and that vitamins and Oriental supplements are the 2 top-ranked DSs. Reasons for DS use were to improve recovery ability (66%) and muscle performance (22%), and sources of obtaining DSs were parents (36%) and coaches (35%). Furthermore, 79% of Korean Olympians reported receiving regular education on antidoping regulations from Olympic-sponsored education classes (64%) and coaches (15%). In conclusion, this study was the first to examine DS use and antidoping-related information in Korean Olympians. Because some herbal products contain substances banned by the World Anti-Doping Agency, athletes should be cautious in using mixed Oriental supplements.

This article describes the development, analysis, and implementation of the menu available to athletes and patrons in the main dining hall of the Athletes Village at the Sydney 2000 Olympic Games and the significant role of sports dietitians in this process. Menu design and development was informed by focus groups, literature reviews, and food-preference surveys of athletes. The final menu was also assessed by an expert panel of Australian sports dietitians. A custom-designed database (Foodweb) was developed to enable dietary analysis of food-production data and creation of point-of-choice nutrition labels. Dietitians assisted with quality assurance testing and training of catering staff. Athletes surveyed in the main dining hall (N = 414) agreed that the menu contained sufficient variety and adequate meat, pasta/rice, vegetable/salad, fruit, and snack items. Sports dietitians played a significant role in ensuring that the menu met the needs of athletes from a range of differing cultural and sporting backgrounds. Dining-hall patrons provided positive feedback and few complaints about the overall dining experience. The information presented in this report can help future caterers and dietitians with the planning and provision of suitable food for athletic performance at an Olympic Games.

The purposes of this study were to (a) determine the mechanical factors associated with successful performance of the handspring and salto forward vault at the 1988 Olympic Games, and (b) contrast the findings in this study to those from the 1986 USA Championships to gain additional insight for the improvement of performance. The subjects were 51 male gymnasts in the 1988 Olympic Games. Significant correlations indicated that the following were important determinants for successful results: (a) large horizontal velocity (VH) at takeoff (TO) from floor and board resulting from a fast sprint in the approach run; (b) a large change of vertical velocity (Vv) during the horse contact by means of blocking with arms and shoulders; and (c) large VH and Vv at TO from horse, which ensures great distance and height and a long time of postflight, which the judges are seeking. Comparison of the techniques between the two groups revealed that the Olympic gymnasts achieved significantly greater horizontal velocity in preflight, change of vertical velocity while on horse, and vertical velocity at takeoff from horse, which resulted in a significantly longer time of postflight than for the USA gymnasts. An analysis of the aspect of form in postflight, possibly by means of mechanical variables, should be conducted because it may provide additional insight for improvement for performance of this vault.

Two of the most frequently performed vaults in the 1988 Olympic Games in Seoul were selected for 3-D cine-photogrammetry analysis: the Yurchenko layout with full twist and the Yurchenko layout. The performances included 20 vaults with the highest performance scores: 10 Yurchenko layout with Ml twist (YLF) and 10 Yurchenko layout (YL) vaults, which were performed in the women’s team optional competitions. The YLF group earned higher performance scores than the YL group. Average vaulting times were similar for the groups, but the YLF group showed shorter board and horse contact times and longer postflight times. The projectile motion variables were critical for better performance in the YLF group. Higher vertical velocity at horse takeoff was achieved mainly by minimizing its (Vv) loss during horse contact. The YL group showed the importance of angular momentum for better performance, with the normalized angular momentum during postflight being the critical variable for the YL vault.

Twelve male 100-m freestyle swimmers were videotaped during the 1992 Olympic Games. Four cameras, two above water and two below, recorded the same stroke cycle of the swimmer at approximately the 40- to 45-m mark. The whole body and the recovering arms were digitized from the videotapes to recreate a complete stroke cycle. Body position variables and hand reaction forces (Schleihauf, 1979) were calculated. Swimmers were divided into elite and subelite groups based on their swimming velocity and were compared for differences in biomechanical variables. Elites used slightly lower hand forces while maintaining a higher propelling efficiency. Subelites had opposite rotations about the longitudinal axis of the body rather than symmetrical body roll. The elite swimmers were different from subelites in that their pulling patterns were more efficient and their body position was more streamlined. These variables assisted them in achieving faster swimming velocities without requiring higher propulsive forces.

The performances of 335 male and female swimmers competing in 50-, 100-, and 200-m freestyle events at the 1992 Barcelona Olympic Games were videotaped and analyzed to determine stroke length (SL), stroke rate (SR), starting time (ST), turning times (TI = turn in, TO = turn out), finishing (end) time (ET), and average velocity (AV); relationships were then determined among these variables in addition to height, weight, age, and final time (FT). Differences were subsequently assessed within and among the events, and comparisons were made between male and female performances. ST, TI, TO, ET, and SL were identified as principal components of successful swimming performance at each distance. Results revealed statistically significant correlations between factors for all events. The men were older and taller; possessed longer stroke lengths; and started, turned, and swam faster than the women. As the race distance increased from 50 to 200 m, ST, TI, TO, SL, and ET increased for both men and women, while age, SR, and AV decreased.

The 20 highest scored handspring with full-turn vaults performed during the 1992 Olympic Games were compared with those receiving the 20 lowest scores. Hypotheses were that the vaults receiving high scores would (a) demonstrate larger horizontal velocity at takeoff from the board and larger vertical velocity at takeoff from the horse and (b) demonstrate greater amplitude of postflight, higher center of gravity (CG) at the completion of the full twist, and superior landing performance than those receiving low scores. Two 16-mm Locam II DC cameras, each operating at a nominal frame rate of 100 Hz, recorded the vaults. It was concluded that the vaults receiving high scores demonstrated (a) larger horizontal velocity and translational kinetic energy at takeoff from the board, larger vertical velocity and translational kinetic energy at takeoff from the horse, and greater amplitude of postflight; (b) greater heights of CG from the beginning of the second-quarter twist to halfway through the third-quarter twist; and (c) superior landing performance than those receiving low scores.
