The availability of female role models is examined through a content analysis of Young Athlete magazine. Two research questions are posed: Do males and females receive differential treatment in Young Athlete? Does the representation of males and females in Young Athlete reflect actual participation rates? Young Athlete depicts sport as a male activity. For example, less than one-third of all photographs depict females, and the percentage decreases with the prominence of the photograph. Compared to actual participation rates, Young Athlete subtly distorts girls’ involvement. Girls are markedly under-represented in team sports, even those they dominate numerically. Discussion focuses upon the issue of fair treatment. The conclusion that statistical representation is a safe but narrow definition of fair treatment is explored with reference to current theoretical perspectives on media.

The aim was to develop a path-flow analysis model for young swimmers’ performance based on biomechanical and energetic parameters, using structural equation modeling. Thirty-eight male young swimmers served as subjects. Performance was assessed by the 200-m freestyle event. For biomechanical assessment the stroke length, the stroke frequency and the swimming velocity were analyzed. Energetics assessment included the critical velocity, the stroke index and the propulsive efficiency. The confirmatory model explained 79% of swimming performance after deleting the stroke index-performance path, which was nonsignificant (SRMR = 0.06). As a conclusion, the model is appropriate to explain performance in young swimmers.

The benefits of training, rest, and proper nutrition in athletic performance are unquestionable. In the case of young athletes, the important role of nutrition in growth and development should also be considered ( Cotugna et al., 2005 ). To understand the importance of daily food choices and

Purpose:

The purpose of this intervention study was to investigate if a low-dose of plyometric training (PT) could improve sprint and jump performance in groups of different maturity status.

Method:

Male youth field hockey players were divided into Pre-PHV (from -1 to -1.9 from PHV; Experimental: n = 9; Control = 12) and Mid-PHV (0 to +0.9 from PHV; Experimental: n = 8; Control = 9) groups. Participants in the experimental groups completed 60 foot contacts, twice-weekly for 6 weeks.

Results:

PT exerted a positive effect (effect size: 0.4 [-0.4–1.2]) on 10 m sprint time in the experimental Mid-PHV group but this was less pronounced in the Pre-PHV group (0.1 [-0.6–0.9]). Sprint time over 30 m (Mid-PHV: 0.1 [-0.8–0.9]; Pre-PHV: 0.1 [-0.7–0.9]) and CMJ (Mid-PHV: 0.1 [-0.8–0.9]; Pre-PHV: 0.0 [-0.7–0.8]) was maintained across both experimental groups. Conversely, the control groups showed decreased performance in most tests at follow up. Between-group analysis showed positive effect sizes across all performance tests in the Mid-PHV group, contrasting with all negative effect sizes in the Pre-PHV group.

Conclusion:

These results indicate that more mature hockey players may benefit to a greater extent than less mature hockey players from a low-dose PT stimulus. Sixty foot contacts, twice per week, seems effective in improving short sprint performance in Mid-PHV hockey players.

The aim of this study was to determine whether elderly and young adults with similar physical activity levels have similar soleus H-wave maximum/M-wave maximum ratios (H-reflex size) and to determine the relationship between H-reflex size and physical activity level. H-reflex size and physical activity levels were measured in 18 elderly (71 ± 5.7 years) and 20 young (24 ± 4.2) participants. The physical activity levels of the 2 groups were not significantly different. The elderly group had smaller H-rellexes than the young group (elderly. 36% ± 27%; young, 59% ± 17%; p < .05), but the effect of age on H-reflex size was only moderate (omega squared = .19, effect size = .30). There was a weak tendency for higher levels of physical activity to be associated with larger H reflexes (r = .38, p < .05). The findings indicate that soleus H-reflex size is not strongly associated with age or physical activity level.

Young competitive athletes are not miniature elite athletes; they are a distinct client group to whom sport psychology practitioners (SPPs) increasingly deliver services. Interventions with this client group are often undertaken by newly educated SPPs who are in need of good guiding principles. Yet, there is a lack of research informing SPPs’ work with this group. In this current study, semistructured qualitative interviews were conducted with four experienced practitioners about their most successful interventions in competitive youth sport. Analysis showed three major themes: (a) young athletes should be equipped with a holistic skills package that enables them to handle a number of existential challenges; (b) young athletes are embedded in an environment (coaches, experts, teammates etc.) that should be involved in the interventions; and (c) interventions with young athletes should maintain a long-term focus. These themes are discussed in the context of current literature on sport psychology service delivery.

Background:

There are concerns about the future health of young people due to inactive lifestyles. However, evidence about their physical activity levels is not extensive, especially with regard to affluent young people. This study aimed to investigate whether young people from affluent backgrounds met public health recommendations for physical activity.

Methods:

Diary accounts of lifestyle activity were collected from 219 students ages 9 to 15 y attending a fee-paying school in England.

Results:

Pupils spent an average of 121 min per day participating in physical activities of at least moderate intensity, considerably more than public health recommendations of 60 min per day. However, almost a quarter of these young people engaged in less than 60 min of physical activity per day of at least moderate intensity.

Conclusions:

The picture to emerge was one of a balance between sedentary pursuits like television and homework and physical activities such as sport and active play.

The five basic emotions expressed by these faces were happiness, sadness, anger, disgust, and fear. Following a

The purpose of this study was to develop a theoretical understanding of what could influence exercise adherence in physically non-active young women. Interviews with twelve physically nonactive young women were strategically selected and analyzed by grounded theory. The results were that several factors could influence exercise adherence in physically non-active young women, and that these factors can be regarded as a number of interrelated dimensions. The influence was coming either from the exercise or from the environment connected to the exercise. The participants wanted to feel enjoyment and to learn something during the exercise (recreation/learning influence). They also wanted to feel belongingness during the exercise (social influence). An influence that promotes health or builds skills (investment influence) could be a trigger to start exercising among the participants, but not to maintain exercise adherence. Influence coming from the environment (enabling influence) was both important and stimulating for physically non-active young women in establishing regular exercise. It is important to present the model developed in this study to communities, sports federations and other authorities working with health promotion activities so that they can explore innovative ways to promote exercise adherence among physically non-active young women. Good examples could be to offer non-competitive sports as well as to develop well-designed exercise programs for physically non-active young women.
