Perception of Coaching Behaviors, Coping, and Achievement in a Sport Competition
2011
This study examined the relationship between perceived coaching behaviors, coping strategies during a sport competition, and sport achievement. A prospective design was used in which 80 athletes from individual sports completed measures of perceived coaching behaviors two days before a competition (Time 1) and measures of coping and sport achievement within three hours after a sport competition (Time 2). As expected, results of multiple regressions indicated that supportive coaching was a positive predictor of task-oriented coping and sport achievement whereas unsupportive coaching was a positive predictor of disengagement-oriented coping. Both types of coping were significantly associated …
The role of the right temporo-parietal junction in social decision-making
2018
Identifying someone else's noncooperative intentions can prevent exploitation in social interactions. Hence, the inference of another person's mental state might be most pronounced in order to improve social decision‐making. Here, we tested the hypothesis that brain regions associated with Theory of Mind (ToM), particularly the right temporo–parietal junction (rTPJ), show higher neural responses when interacting with a selfish person and that the rTPJ‐activity as well as cooperative tendencies will change over time. We used functional magnetic resonance imaging (fMRI) and a modified prisoner's dilemma game in which 20 participants interacted with three fictive playing partners who behaved a…
Does being a Stranger make it Difficult to Cooperate?
2017
AbstractCompetition and cooperation are two somewhat opposed strategies for interpersonal social interaction that help us to achieve both individual and shared goals. The main aim of this study was to explore which type of social interaction (cooperative or competitive) is more stressful in a face-to-face same-sex dyad in healthy young participants (n = 178), considering outcome obtained in these tasks (positive or negative) and sex as moderating variables, and performance of the task alone as a control condition. Salivary cortisol (Csal) was measured in one sample obtained before task and four obtained after the task (+0, +15, +30 and +45 minutes after). Anxiety-state was assessed before a…
Determinants of leisure-time physical activity and future intention to practice in Spanish college students
2009
Few studies analyze determinants and patterns of physical activity among college students, so it has not been possible to carry out effective interventions to promote this practice. The aim of this study was to analyze the associations between some personal, social, and environmental determinants, practice of physical activity and future intention to practice in a sample of 639 university students (321 men and 318 women), mean age 21.43 years (+/- 2.78). Physical fitness self-perception, physical activity history, and coach's support to practice physical activity have a direct effect on the practice of physical activity and an indirect effect on future intention to practice, both in men and…
Testosterone, Cortisol, and Mood in a Sports Team Competition
1999
In 1 humans, hormonal responses to winning/losing and their relationships to mood and status change have mostly been examined in individual athletic competitions. In this study, the salivary testosterone (T) and cortisol (C) and mood responses to a real match between two professional basketball teams were investigated. Data about individuals’ contributions to outcome, performance appraisal, and attribution of outcome to internal/external factors were also collected. Results did not show statistically significant different T and C responses depending on the outcome. Negative mood was significantly enhanced, especially in the losers, while winners showed a better appraisal of team performance…
Predictor variables for a 100-km race time in male ultra-marathoners.
2010
In 169 male 100-km ultra-marathoners, the variables of anthropometry, training, and prerace experience, in order to predict race time, were investigated. In the bivariate analysis, age ( r = .24), body mass ( r = .20), Body Mass Index ( r = .29), circumference of upper arm ( r = .26), percent body fat (r = .45), mean weekly running hours ( r = –.21), mean weekly running kilometers ( r = –.43), mean speed in training ( r = –.56), personal best time in a marathon ( r = .65), the number of finished 100-km ultra-runs ( r = .24), and the personal best time in a 100-km ultra-run ( r = .72) were associated with race time. Stepwise multiple regression showed that training speed ( p < .0001), me…
The effect of different starting procedures on sprinters' reaction time.
2012
We examined the effect of different false start rules and starters' holding time on athletics sprinters' reaction times. Reaction times from 210 female (25.2 ± 3.8 years) and 361 male (24.8 ± 3.8 years) 100 m sprinters, participating in international championships for seniors from 1997 to 2011, were analysed. Holding time calculations were based on television recordings from the analysed heats (n = 267). Mean reaction times have increased by 20% (0.03 s, P0.001) during a 15 year period due to stricter false start rules. Starters' holding times were between 1.3 and 2.2 s for the analysed competitions. There was a small but significant relationship between reaction time and starters' holding …
Sex differences in autonomic response and situational appraisal of a competitive situation in young adults.
2017
Competition is a social stressor capable of eliciting physiological responses modulated by the outcome. The main objective of this study was to analyze the psychophysiological changes associated with competition and its outcome in men and women, taking into account the role of situational appraisal. To this end, 112 young people (46 men and 66 women) participated in a laboratory task in a competitive or non-competitive condition, while Blood Pressure (BP), Heart Rate Variability (HRV), and Skin Conductance (SC) responses were measured. Our results indicate that competition elicits higher systolic blood pressure (SBP) than a non-competitive task; in addition, winners presented a greater R-R …
Correlating testosterone and fighting in male participants in judo contests
2000
The role of hormones in human aggression is open to debate, but takes on a new urgency owing to the alarming abuse of androgenic anabolic steroids by some sports participants. In this study, video-taped behavior exhibited by 28 male competitors during a judo fight was assessed to analyze its relation to serum testosterone and cortisol levels measured before and after the bouts. A positive relation between testosterone and offensive behaviors was obtained in the sense that the greater the hormonal titer, the greater the number of threats, fights, and attacks. These findings coincide with the pattern of relationships found using observational scales. Conversely, cortisol also presented positi…
Relationships between recall of perceived exertion and blood lactate concentration in a judo competition
2001
Relationships between perceived exertion and blood lactate have usually been studied in laboratory or training contexts but not in competition, the most important setting in which sports performance is evaluated. The purpose of this study was to examine the relationships between psychological and physiological indices of the physical effort in a competition setting, taking into account the duration of effort. For this, we employed two Ratings of Perceived Exertion (RPE and CR-10) and lactic acid plasma concentration as a biological marker of the effort performed. 13 male judo fighters who participated in a sports club competition provided capillary blood samples to assay lactate concentrat…
