In the past decade, to help maintain political stability and promote economic growth, South Korea has committed substantial resources to commercialized sports, including golf. A major source of support for building golf courses has come from government leaders and economic and social incentives as well. In the past 4 years the government has given permission to build 135 new golf courses. The official government discourse about the new golf courses is that they are being built in the interest of “sport for all.” But the golf courses overwhelmingly require membership, which is extremely expensive. Despite the enormous power and resources of the dominant groups in Korea, there are elements of opposition. The golf boom has been severely criticized because it removes large amounts of land from agricultural and industrial productivity, contaminates farm land, and pollutes water. It also represents the worst aspects of the social imbalance of wealth.

Changes in strength over the course of a swim season could predispose the shoulder to strength imbalances and lead to injury.
To examine isometric shoulder internal- (IR) and external-rotator (ER) strength in high school swimmers over a 12-week competitive season.
Three 3 × 2 × 2 ANOVAs with repeated measures were used to determine significant main effects for IR, ER, and IR:ER strength ratio.
27 (14 female, 13 male) high school varsity swimmers.
Main Outcome Measures:
IR and ER strength during preseason, midseason, and postseason.
Significant increases in IR strength in both groups were revealed for all test sessions. ER strength significantly improved in both males and females from preseason to midseason and from preseason to postseason. IR:ER ratio revealed a significant increase from preseason to postseason.
Increases in IR strength without equal gains in ER strength were revealed and could contribute to future shoulder pathologies in competitive swimmers

In contrast to traditional approaches to research, participatory action research calls for the active involvement of the community—including both the beneficiaries and providers of sport services—in defining research problems, executing interventions, interpreting results, and designing strategies to change existing power structures. The purpose of this paper was to analyze a participatory action research project designed to increase the access of women living below the poverty line and their families to local physical activity services. A framework developed by Green et al. (1995) formed the basis of the analysis. To place the analysis in context, the historical origins and theoretical assumptions underlying participatory action research were addressed. The case of the Women's Action Project demonstrated how the process can result in a more inclusive local sport system and, at the same time, provide a rich setting for examining organizational dynamics including collaborative decision-making, community partnerships, power imbalances, resource control, resistance to change, and nonhierarchical structures.

This paper introduces the concept of dynamic isometrics in training athletes to improve core/postural-related movements while potentially decreasing the occurrence of injury manifested as lower back pain (LBP). Moreover, suggested resistance-training exercises are provided to guide the sport coach. Lower back pain is a common musculoskeletal injury that can be caused by imbalances between anterior and posterior muscle groups. Traditional exercises such as sit-ups and crunches are insufficient as preventatives because very few athletic movements are performed with weighted trunk flexion. Alternatively, sport coaches could implement dynamic isometric training, which closely reflects athletic activities, supports the principle of training specificity, improves balance and strength, and might decrease the occurrence of LBP (Hamlyn, Behm, & Young, 2007).

Since the publication of the seminal review on youth resistance training by Kraemer and colleagues in 1989, a compelling body of evidence has found that resistance training can be a safe, effective, and worthwhile method of conditioning for children and adolescents. New perspectives for promoting resistance exercise as part of a long-term approach to youth physical development highlight the importance of integrating resistance training into youth fitness programs. Youth who do not enhance their muscular strength and motor skill proficiency early in life may not develop the prerequisite skills and abilities that would allow them to participate in a variety of activities and sports with confidence and vigor later in life. The identification of asymptomatic children with muscular weaknesses or imbalances may facilitate the development of a management plan which should rectify movement limitations and educate children and their families about the importance of daily physical activity.

Body water and electrolyte balance are essential to optimal physiological function and health. During exercise, work, or high temperatures, a significant level of dehydration can develop, and the ratio of extracellular to intracellular fluid can change, despite an ample supply of water. Physical and cognitive performance are impaired at 1-2% dehydration, and the body can collapse when water loss approaches 7%. Because fluid needs and intakes vary, formulating one general guideline for fluid replacement is difficult. Knowing the amount of water lost in sweat may enable predicting fluid needs via mathematical models for industrial, athletic, and military scenarios. Sodium imbalance might result from excessive Na+ loss or from gross o verity dration. In most work or exercise lasting < 3-4 hr, the major concern is that fluid be available to prevent heat-related illnesses, which can be prevented if fluid and electrolyte losses are balanced with intake, using the recommendations presented.

This paper sought to examine the stakeholder network governance structures of two international and two domestic multisports events focusing on (a) exploring the structural connectedness of these networks and (b) illuminating powerful stakeholders vis-à-vis centrality and the ability to control the network’s flow. An exploratory, comparative case study design was built by means of 58 interviews and 550 archival materials. Findings highlight international sports events are sparsely connected networks with power concentrated in the organizing committee, government, and venue stakeholders, who broker coordination with other stakeholders. In contrast, domestic sport event organizing committees appear more decentralized as coordinating actors: Sport organizations, sponsors, and community-based stakeholders emerged as highly connected, powerful stakeholders. Domestic event governance decentralization highlights a potential imbalance in stakeholder interests through network flow control by multiple actors, while the governments’ centrality in international events demonstrates not only mode-dependent salience but also visibility/reputational risks and jurisdictional responsibilities-based salience.

The aims of the study were to investigate the differences in kinematics and kinetics between the dominant and nondominant leg during single-leg jumps without arm swing, and to determine the relationship between bilateral asymmetry in isokinetic knee strength and the single-leg jump. Isokinetic knee strength and single-leg jump kinematics and kinetics were measured in 11 male participants. The bilateral asymmetry index was calculated for each parameter. For isokinetic knee strength, there were no significant differences between the dominant and nondominant legs. Significant correlations were observed for the bilateral asymmetry index for isokinetic knee strength at 180 degrees per second and the bilateral asymmetry indexes for maximum flexion angle and the mean knee joint torque during the single-leg jumps. In conclusion, the findings of the current study suggest an association between knee strength imbalances and the joint angle, as well as the torque produced in single-leg jumps, although no relationship between knee strength and jump height was observed.

An understanding of the health consequences of abnormal menstrual function is an important consideration for all exercising women. Menstrual disturbances in exercising women are quite common and range in severity from mild to severe and are often associated with bone loss, low energy availability, stress fractures, eating disorders, and poor performance. The key factor that causes menstrual disturbances is low energy availability created by an imbalance of energy intake and energy expenditure that leads to an energy deficit and compensatory metabolic adaptations to maintain energy balance. Practical guidelines for preventing and treating amenorrhea in exercising women include evidence-based dietary practices designed to achieve optimal energy availability. Other factors such as gynecological age, genetics, and one’s susceptibility to psychological stress can modify an individual’s susceptibility to menstrual disturbances caused by low energy availability. Future research should explore the magnitude of these effects in an effort to move toward more individualized prevention and treatment approaches.
The under-representation of women in sport management has increasingly been recognized by government and nongovernment organizations, and there has been some attempt to redress the imbalance. Research has indicated, however, that the gendering of sport organizations is not simply a numbers’ game. The purpose of this study was to analyze the exercise of exclusionary power as an aspect of gender relations within a six member volunteer Board of Directors of an Australian local, grass-roots sport organization. Data were gathered using semistructured interviews, participant observation and documentary evidence over a 15-month period. This study identified that, although numerical underrepresentation of men or women on this Board was not an issue for either sex, exclusionary power was exercised in a number of overlapping ways which ultimately limited the participation, input, and influence of its female members.
