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…
Comparison of service tactic formation on players’ movements and point outcome between national and beginner level padel
2021
The aim of this study was to analyze the influence of service tactic formation on players’ movements and point outcome at two different performance levels. The sample contained 2,148 points corresponding to 18 matches from two male padel indoor tournaments. Players were classified according to their game level: high-level (N = 36; age = 33.3 ± 6.9 years) and beginner (N = 36; age = 35.4 ± 6.8 years). Variables pertaining to service tactic formation (conventional or Australian), point outcome and movement patterns were analysed from the matches through systematic observation. The results showed how high-level players used a significantly higher percentage of the Australian formation than beg…
fMRI-activation patterns in the detection of concealed information rely on memory-related effects
2012
Recent research on potential applications of fMRI in the detection of concealed knowledge primarily ascribed the reported differences in hemodynamic response patterns to deception. This interpretation is challenged by the results of the present study. Participants were required to memorize probe and target items (a banknote and a playing card, each). Subsequently, these items were repeatedly presented along with eight irrelevant items in a modified Guilty Knowledge Test design and participants were instructed to simply acknowledge item presentation by pressing one button after each stimulus. Despite the absence of response monitoring demands and thus overt response conflicts, the experiment…
Psychophysiological responses to cooperation: The role of outcome and gender
2013
Instances of sustained cooperative behaviour in humans can be considered as an adaptive strategy that enhances the probability of reaching a goal. This study investigates psychophysiological responses to cooperation in healthy subjects, while considering outcome and gender as potential moderators of these responses. Salivary cortisol levels (Csal), heart rate (HR), skin conductance level (SCL), nonspecific skin conductance responses (NSRs), and mood states were measured at different points before, during and after a Lego house-building task in undergraduate men (n = 22) and women (n = 20). Once the task was finished, the experimenter informed the participants about the outcome obtained (pos…
Collagen ultrastructure in ruptured cruciate ligaments
1992
The ultrastructure of collagen fibrils was investigated in normal (n 39) and ruptured (n 23) human anterior cruciate ligaments. The normal ligament had a complex three-dimensional structure. Collagen fibrils predominantly had a unidirectional course with parallel arrangement and a mean diameter of 75 (20-185) nm. Four days after anterior cruciate ligament rupture, the mean fibril diameter was increased; it later decreased, probably due to synthesis of young, thin 30-40 nm fibrils. Interfibrillar dysplastic collagen fibrils were detected in the extracellular matrix of ruptured ligaments. They were more frequently found later than 3 days after rupture and were seen also at a distance of 2-3 c…
Cognitive Biases and Decision Making in Gambling
2010
Heuristics and cognitive biases can occur in reasoning and decision making. Some of them are very common in gamblers (illusion of control, representativeness, availability, etc.). Structural characteristics and functioning of games of chance favor the appearance of these biases. Two experiments were conducted with nonpathological gamblers. The first experiment was a game of dice with wagers. In the second experiment, the participants played two bingo games. Specific rules of the games favored the appearance of cognitive bias (illusion of control) and heuristics (representativeness and availability) and influence on the bets. Results and implications for gambling are discussed.
Cellular ultrastructure of the ruptured anterior cruciate ligament. A transmission electron microscopic and immunohistochemical study in 55 cases.
1994
To evaluate the cellular ultrastructure following injury, we examined the anterior cruciate ligaments in 55 patients with complete tears in different phases after the injury and compared them to a control group of 39 cadaver knees. Samples were analyzed by electron microscopy, immunofluorescence, and ultramorphometry. After an invasion of inflammatory cells into the stumps of the ruptured ligaments, a marked proliferation of fibroblasts was found at the end of Phase 1 (2-3 days after the ligament injury), that was even more pronounced at the beginning of Phase II (4-17 days). These cells were initially highly metabolically active and secreted Type III collagen precursors. In Phase III (4-45…
Acute effects of strength exercises and effects of regular strength training on cell free DNA concentrations in blood plasma.
2017
Creatine kinase (CK) is a marker for muscle cell damage with limited potential as marker for training load in strength training. Recent exercise studies identified cell free DNA (cfDNA) as a marker for aseptic inflammation and cell damage. Here we overserved in a pilot study the acute effects during strength exercise and chronic effects of regular strength training on cfDNA concentrations over a period of four weeks in three training groups applying conservation training (CT) at 60% of the 1 repetition maximum, high intensity-low repetition training (HT) at 90% of the 1 repetition maximum and differential training (DT) at 60% of the 1 repetition maximum. EDTA-plasma samples were collected b…
Two-year outcome in first-episode psychosis treated according to an integrated model. Is immediate neuroleptisation always needed?
2000
SummaryIn this multicentre study the two-year outcome of two groups of consecutive patients (total N = 106) with first-episode functional non-affective psychosis, both treated according to the ‘need-specific Finnish model’, which stresses teamwork, patient and family participation and basic psychotherapeutic attitudes, was compared. No alternative treatment facilities were available in the study sites. The two study groups differed in the use of neuroleptics: three of the sites (the experimental group) used a minimal neuroleptic regime whilst the other three (the control group) used neuroleptics according to the usual practice. Total time spent in hospital, occurrence of psychotic symptoms …
The relevance of cognitive, clinical and premorbid variables in predicting functional outcome for individuals with first-episode psychosis: A 3 year …
2013
Real-world functional deficits are common and persistent in individuals with psychosis. Cognitive deficits have been shown to compromise functioning. We aimed to study the predictive values of premorbid, sociodemographic, and baseline clinical and neurocognitive factors on long-term functional outcome for individuals with first episode non-affective psychosis. We failed to demonstrate a significant relationship between cognitive deficits at baseline and functional disability at 3 year follow-up. Diagnosis of schizophrenia (OR=2.457, p=0.011), shorter education (OR=1.177, p=0.005) and poor premorbid social adjustment (OR=1.628, p=0.013) emerged as the strongest predictors for the 114 subject…
