#1
Kenneth H Cooper
Looking back over the 50 years since Aerobics was published, I could never have expected for there to have been a major change in physicians' attitudes toward the value of exercise in the practice of medicine. In my lifetime, I never thought I would see a stress test be considered a mandatory component of a complete examination, inactivity classified as importantly as high blood pressure and high cholesterol, and cigarette smoking considered a coronary risk factor. I have tried in this Research Quarterly for Exercise and Sport (RQES) Lecture presentation to document how this slow but gradual transition took place due to my work and the work of many of my colleagues in this field, along with the important work of The Cooper Institute...

PURPOSE: Although motor skill interventions often improve fundamental motor skills (FMS) during preschool, the extent of individual children's success in development of FMS still varies among children receiving the same intervention. Temperament is multifaceted and includes negative affect (high levels of frustration or anger), effortful control (focus, self-regulation, and concentration), and surgency (energy and activity level). Temperament often influences cognitive, social, and behavioral outcomes and may be a significant factor in the development of FMS...

Research from several countries has documented a decline in physical activity (PA) levels and in participation in organized sport with increasing age, indicating that organized sport may be of importance to adolescents' cardiorespiratory fitness (CRF). PURPOSE: The purpose of this study was to examine how regular participation in organized and unorganized PA affected the development of adolescents' CRF (peak oxygen consumption [VO2 peak]), when controlled for sex interaction. METHOD: Data on direct measures of VO2 peak and participation in organized PA among adolescents organized into 3 groups (participation in organized sport, participation in unorganized PA, and no weekly PA) were collected from 76 students (39 boys and 37 girls), when they were aged 14 and 19 years old...

PURPOSE: A large pool of evidence supports the beneficial effect of an external focus of attention on motor skill performance in adults. In children, this effect has been studied less and results are inconclusive. Importantly, individual differences are often not taken into account. We investigated the role of working memory, conscious motor control, and task-specific focus preferences on performance with an internal and external focus of attention in children. METHODS: Twenty-five children practiced a golf putting task in both an internal focus condition and external focus condition...

PURPOSE: Physical educators may be the responsible people for implementing comprehensive school physical activity programs (CSPAPs) in schools. However, it is unclear whether physical education teacher education (PETE) programs provide the relevant learning opportunities to preservice teachers for CSPAP implementation. The purpose of this study was to understand preservice teachers' perspectives and experiences of CSPAP preparation in their PETE programs. METHOD: Fourteen PETE students from 6 different universities participated and shared their experiences in PETE programs...

PURPOSE: This study aimed to investigate the effects of water-based aerobic training on the lipid profile and lipoprotein lipase (LPL) levels in premenopausal women with dyslipidemia. METHOD: Forty women were randomly assigned to: aquatic training (WA; n = 20) or a control group (CG; n = 20). The WA group underwent 12 weeks of water-based interval aerobic training twice a week at intensities ranging from 9 to 15 on the Borg Scale of Perceived Exertion. Total cholesterol (TC), triglycerides (TG), high- (HDL) and low- (LDL) density lipoprotein, TC/HDL ratio, LPL levels, and peak oxygen consumption (VO2 peak) were evaluated before and after 12 weeks in both groups...

PURPOSE: Acute benefits of aerobic exercise on executive functioning have been reported frequently under laboratory conditions. However, to date, a beneficial effect on long-term memory has been less well supported and no data are available regarding nonlaboratory conditions in young adults. The aim of the current study was to investigate acute effects of aerobic exercise on cognitive functioning in a university classroom setting. METHOD: Using a cross-over design, 51 participants performed a bout of moderately intense running (RUN) and read an article while seated (CON)...

Gymnastics judges and former gymnasts have been shown to be quite accurate in detecting errors and accurately judging performance. PURPOSE: The purpose of the current study was to examine if this superior judging performance is reflected in judges' gaze behavior. METHOD: Thirty-five judges were asked to judge 21 gymnasts who performed a skill on the vault in a video-based test. Classifying 1 sample on 2 different criteria, judging performance and gaze behavior were compared between judges with a higher license level and judges with a lower license level and between judges who were able to perform the skill (specific motor experience [SME]) and those who were not...

PURPOSE: The net height in tennis (0.91 m) is approximately 50% of a professional tennis player's height. Children are also expected to play with this net height, even though it is approximately 70% of the average 10-year-old's height. This study examined the immediate effect of lowering net height on the performance characteristics of skilled junior tennis players aged 10 years and younger. METHOD: Sixteen players were matched in 8 pairs of even tennis ability and same sex...

Physical education is critical to addressing childhood obesity, yet many school-based programs do not meet established quality standards and teachers are called upon to change. Little is known about how change is initiated and its associated internal and external factors. PURPOSE: The purpose of this study was to investigate physical education teacher change that was self-initiated and externally initiated and to examine dispositions toward the change process relative to initiation. METHOD: A random national sample of physical educators representing each SHAPE America - Society of Health and Physical Educators regional district participated in a survey measuring past programming changes, primary initiators of change, and teachers' dispositions toward change...

PURPOSE: Several studies have demonstrated that physiological variables predict cycling endurance performance. However, it is still unclear whether the predictors will change over different performance durations. The aim of this study was to assess the correlations between physiological variables and cycling time trials with different durations. METHODS: Twenty trained male cyclists (maximal oxygen uptake [VO2 max] = 60.5 ± 5.6 mL/kg/min) performed 4 separate experimental trials during a 2-week period...
