Recent research into the use of anabolic androgenic steroids (AAS) in fitness and strength training environments have revealed great variance in users’ approach to AAS use and more specifically their approach to health risks and desired objectives. However, there have only been few attempts to develop theoretical frameworks directed at conceptualising the variance in AAS use. In this paper, we propose a unified framework in the form of a typology, which concerns men’s general approach to AAS use. The typology is based on sociologist Max Weber’s method on the ideal typology. The work comes out of the authors’ own qualitative empirical research on male AAS users in fitness and strength training environments, but is also related to and draws on the international literature on the subject. The suggested typology consists of four ideal types: the Expert type, the Well-being type, the YOLO type and the Athlete type. The four types are developed around two overarching categories, namely users’ approach to risk and effectiveness. The typology outlines distinct and characteristic approaches to AAS use and can, thus, be employed by researchers as well as health professionals as a heuristic tool for investigation and explanation. 相似文献

We examined the influence of nutritional status, body fat, and anemia on the physical fitness (PFI) of tribal adolescents. Weight, height, skinfold thickness, PFI, and hemoglobin levels of 147 adolescents (11 to 16 years) were measured. The experience of cycling was recorded. Overall, 31.3% were mildly, 12.9% were moderately, and 10.9% were severely thin. The majority (81.6%) were nonanemic. All had “poor” PFI scores. Hemoglobin levels were significantly associated with PFI scores in boys and girls. Experience of cycling also predicted PFI in girls. Nutritional status, hemoglobin level, and physical activity were associated with the fitness levels of these adolescents. 相似文献

Abstract Worksite interventions have the potential to reach a broad and captive audience and overcome one of the most widely cited barriers to increasing physical activity (PA), namely, a lack of time. A systematic review and random effects, meta-analysis assessed the effectiveness of worksite interventions to enhance PA. Thirty-seven intervention evaluations reporting 55 unique interventions met our inclusion criteria. Results indicate that, overall, worksite interventions have small, positive effects on PA and this effect is smaller when fitness, as opposed to self-report, outcome measures are reported (ds = 0.15 versus 0.23). Worksite interventions targeting PA specifically as opposed to general lifestyle change were found to be more effective whether evaluated in terms of increased fitness (0.29 versus 0.08) or increased self-reported PA (0.27 versus 0.14). Those promoting walking as opposed to other forms of PA were also more effective (0.54 versus 0.16). Interventions providing individually tailored information or instructions were not found to be more effective, but there was evidence that specific goal setting and goal review techniques may enhance fitness gains. 相似文献

Children with developmental language disorders (DLD) often experience difficulty in understanding and engaging in interactive behavior with other children, which may lead to reduced daily physical activity and fitness levels. The present study evaluated the physical activity and physical fitness levels of 8–11 year old children with DLD (n = 27) and compared this to typically developing (TD) age and gender matched controls (n = 27). In addition, it was investigated whether interrelationships existed between physical activity and physical fitness in children with DLD and in TD children. Physical activity was measured using accelerometers. Physical fitness was measured using five tests of the Eurofit test battery (standing broad jump (SBJ), sit-ups (SUP), handgrip (HG), 10 × 5 m shuttle run (10 × 5 m SR), and the 20 m shuttle run test (20 m SR)). Physical activity of children with DLD did not significantly differ from TD children. Physical fitness of children with DLD was significantly lower on the SBJ, SUP, HG and 10 × 5 m SR than TD controls, while no significant difference was found on the 20 m SR. Strong significant relationships were found between physical activity variables and sedentary behavior and some physical fitness measures (SBJ and SUP) in children with DLD, while in TD children a strong significant relationship was found between time spent in moderate to vigorous physical activity and performance on the SBJ. This study reveals important differences in fitness between children with DLD and TD children, which should be taken into account when creating physical activity interventions. Special attention has to be paid to children with DLD who show low physical activity and low physical fitness performance. 相似文献

Among the elderly, smoking is related to death and it contributes to disability associated with chronic diseases. This study aims to verify the influence of a history of smoking on the physical capacity of elderly people, and its relationship with the gender. Elderly people beginning to practice physical activity reported questions about their smoking history and underwent a physical evaluation, consisted by hemodynamic data (blood pressure, heart rate and maximum oxygen consumption), body mass index (BMI), muscular strength, flexibility and balance. Mann-Whitney test and Spearman's test was used to data analysis. The sample consisted of 127 subjects, among whom 26.8% were ex-smokers. There were a higher number of nonsmoking women (p < 0.001) than others, and women smoked fewer packets per day (p = 0.047). Among the women, those ex-smokers were younger and more flexible in comparison with those nonsmokers (p < 0.05). Among the men, the ex-smokers were older and walked more slowly than nonsmokers (p < 0.05). There was a correlation between the BMI and duration of smoking time. Smoking cessation benefits the elderly, since the physical variables showed no long-term harm associated with the history of smoking when compared with those of elderly without this habit. 相似文献
