1 Elite adolescents athletes' achievement goals and beliefs concerning success in tennisThe present study examined the perceived causes of success among elite adolescent tennis players and investigated the function of gender in the interdependence of goal orientation and beliefs concerning tennis achievement. Male and female adolescents (N = 121) completed the Task and Ego Orientation ...Tennis; Athletes; Success1993-12
2 Hormonal changes throughout the menstrual cycle and increased anterior cruciate ligament laxity in femalesOBJECTIVE: To determine whether women experience significantly greater anterior cruciate ligament (ACL) laxity in conjunction with estrogen and progesterone surges during a normal 28- to 30-day menstrual cycle. DESIGN AND SETTING: Serial estrogen and progesterone levels were measured via radioimmuno...Estrogen; Progesterone; Knee Arthrometer; Radioimmunoassay1999-04
3 Lumbar segmental mobility disorders: comparison of two methods of defining abnormal displacement kinematics in a cohort of patients with non-specific mechanical low back painBackground: Lumbar segmental rigidity (LSR) and lumbar segmental instability (LSI) are believed to be associated with low back pain (LBP), and identification of these disorders is believed to be useful for directing intervention choices. Previous studies have focussed on lumbar segmental rotation an...2006
4 Effects of parietal injury on covert orienting of visual attentionThe cognitive act of shifting attention from one place in the visual field to another can be accomplished covertly without muscular changes. The act can be viewed in terms of three internal mental operations: disengagement of attention from its current focus, moving attention to the target, and enga...Dominance, Cerebral; Attention; Extinction, Psychological1984-07
5 Validation of a mathematical model for road cycling powerThis investigation sought to determine if cycling power could be accurately modeled. A mathematical model of cycling power was derived, and values for each model parameter were determined. A bicycle-mounted power measurement system was validated by comparison with a laboratory ergometer.Aerodynamic drag; Rolling resistance; Air velocity; Gradient; Cycling power; Potential energy; Kinetic energy1998
6 Torso stabilization reduces the metabolic cost of producing cycling powerMany researchers have used cycling exercise to evaluate muscle metabolism. Inherent in such studies is an assumption that changes in whole-body respiration are due solely to respiration at the working muscle. Some researchers, however, have speculated that the metabolic cost of torso stabilization...Torso stabilization; Efficiency; Economy; Static contraction; Work2005
7 Time course of learning to produce maximum cycling powerThe purpose of this investigation was to determine the time course and magnitude of learning effects associated with repeated maximum cycling power tests and to determine if cycle-trained men exhibit different learning effects than active men who are not cycle-trained. Cycle-trained (N = 13) and act...Training; Pedaling; Cycle-trained2000
8 Arf 1 dissociates from the clathrin adaptor GGA prior to being inactivated by Arf GTPase-activating proteinsThe effectors of monomeric GTP-binding proteins can influence interactions with GTPase-activating proteins (GAPs) in two ways. In one case, effector and GAP binding to the GTP-binding protein is mutually exclusive. In another case, the GTP-binding protein bound to an effector is the substrate for ...2002
9 Predicting the use of sexual initiation tactics in a sample of college womenSignificant attention has been focused on women's initiation of sexual contact with men and the point at which this initiation becomes sexual aggression. The purpose of this study was to examine possible predictors of the use of three conceptually distinct sets of sexual initiation tactics: seductio...Sexual initiation tactics; Coercion; Force; Social learning theory2004
10 ATGL gene is associated with free fatty acids, triglycerides, and type 2 diabetesAdipose triglyceride lipase (ATGL) was recently described to predominantly perform the initial step in triglyceride hydrolysis and therefore seems to play a pivotal role in the lipolytic catabolism of stored fat in adipose tissue. In the first study investigating genetic variations within the ATGL g...Diabete, Type 2; ATGL; Fat; Triglycerides2006
11 Youth perceptions of a caring climate, emotional regulation and psychological well-beingThe purpose of this study was to examine the meditational effect of perceived affective self-regulatory efficacy on the relationship between youth sport participants? perceived caring climate and their mental well-being. Three hundred and 95 participants (mean age = 11.80 ? 1.54) from a National Yo...2009
12 The new glucose revolution: is the authoritative guide to the glycemic index the right dietary solution for lifelong health?The persistence of an epidemic of obesity, coronary heart disease and type 2 diabetes suggests that new nutritional strategies are needed if the epidemic is to be overcome. A promising nutritional approach suggested by this thematic review is carbohydrate restriction. Under conditions of carbohydra...2010
13 Serum and macular responses to antioxidant supplementation verus a carotenoid-rich dietary intervention in the elderly.The aim of this study was to observe responses of serum antioxidants, oxidative stress biomarkers, and macular carotenoid pigments to antioxidant supplements or dietary intervention in a single-masked, randomized, pilot clinical study of elderly subjects receiving antioxidant supplements or a dietar...Macula; Serum Carotenoids; Zeaxanthin2006-02-01
14 Determination of step rate thresholds corresponding to physical activity intensity classifications in adultsBackground: Current recommendations call for adults to be physically active at moderate and/or vigorous intensities. Given the popularity of walking and running, the use of step rates may provide a practical and inexpensive means to evaluate ambulatory intensity. Thus, the purpose of this study wa...2011
15 Eccentric strain at long muscle length evokes the repeated bout effect.The repeated bout effect (RBE) is a phenomenon characterized by less delayed onset muscle soreness (DOMS) and torque deficit after the second of 2 separate eccentric exercise bouts. Previous investigators have reported that shifting of optimum angle after an initial bout of eccentric exercise mediat...Delayed Onset; Muscle Soreness; Popped Sarcomere; Exercise; Optimum Angle2005-11-19
16 Training with power measurement: a new era in cycling trainingPROVIDING CYCLISTS WITH A reliable measure of exercise intensity presents unique challenges. Environmental factors such as wind speed, road grade and surface texture, and air density interactively influence the resistance encountered during cycling and thus alter the speed a cyclist can maintain wh...Exercise; Intensity; Heart rate2003
17 Influence of leader efficacy and emotional intelligence on personal caring in physical activityScholars in youth development, education, and sport are examining the formative contexts of classrooms, music halls, and playing fields to gain a better understanding of positive development in children. Of particular interest are the leaders in these contexts (e.g., teachers, conductors, and coach...Sport; Motivation; Pedagogy; Leader efficacy; Emotional intelligence2007
18 Relationship of task and ego orientation to performance: cognitive content, affect, and attributions in bowlingThe purpose of the present study was to examine the relationship of individual differences in goal orientation to mid-activity cognitive content and affect and post-performance attributions across three games of bowling. Forty-seven undergraduate students enrolled in bowling activity classes were r...Goal-directed behavior; Task and Ego Orientation in Sport Questionnaire; Sport psychology1993
19 No differences in cycling efficiency between world-class and recreational cyclistsThe aim of this experiment was to compare the efficiency of elite cyclists with that of trained and recreational cyclists. Male subjects (N =69)performed an incremental exercise test to exhaustion on an electrically braked cycle ergometer. Cadence was maintained between 80-90rpm.Gross efficiency; Delta efficiency; Cycling efficiency; Economy; VO2peak2004
20 Senior olympians' achievement goals and motivational responsesThe purpose of this study was to examine the motivational perspectives of athletes participating in the Senior Olympic Games.
