Two hundred twenty athletes volunteered to participate in this study. Challenge of the game and skills of the athlete were measured before and after competition. Thirty minutes after the competition, the FSS was used to measure flow experience. In addition, subjective and objective measures of athletes’ performance were assessed. Athletes in the flow and relaxation states revealed the most optimal states, whereas the athletes in the apathy state showed the least optimal state. There were positive associations between athletes’ flow experience and their performance measures, indicating that positive emotional states are related to elevated ...

This study had two aims: (a) the examination of imagery ability as a moderating variable between imagery type and dispositional flow, and (b) the testing of alternative mediation models. The sample consisted of 367 athletes from Scotland and Australia, who completed the Sport Imagery Questionnaire, Sport Imagery Ability Questionnaire, and Dispositional Flow Scale-2. Hierarchical regression analysis showed direct effects of imagery use and imagery ability on flow, but no significant interaction. Mediation analysis revealed a significant indirect path, indicating a partially mediated relationship (P = 0.002) between imagery use, imagery ability, and flow. Partial mediation was confirmed when the effect of cognitive imagery use and cognitive imagery ability was tested, and a full mediation model was found between motivational imagery use, motivational imagery ability, and fl...

Two hundred and seventy eight athletes completed the Task and Ego Orientation Sport Questionnaire based on how they usually feel. The challenge and skills ratings were completed 1 h before the competition, based on how they felt at the exact time of answering. In the following, the Flow State Scale-2 was completed up to 30 min after the competition they just participated, along with the challenge-skill ratings, based on how athletes felt during the competition. The results indicated that the athletes' task orientation may be an important factor for attaining flow in competitive sport, feeling more skillful and estimating the upcoming competition as challenging, while low ego and low task oriented athletes lack these elements, which are important for them to get into flow. Additionally, not the level of task and ego orientation per se, but the balance between athletes' goal orientation preferences seems important for the formation of flow experience, indicating that high task-high ego and high tasklow ego athletes are experiencing the most positive mental state.

Following evidence for sample-specific validity, the measurement model that underlies the questionnaire was examined. A short-form with 15 items for three factors of Competitiveness (7 items), Win Orientation (5 items) and Goal Orientation (3 items) fit the data (X2/df ratio=2.21, NNFI=.892, CFI=.991, RCFI=.935, SRMR=.058, RMSEA=.071). To evaluate the findings further, we cross-validated the short-form by sex. Structural equation modeling indicated there were similar measurement properties and factor structures for the men and women, indicating similar conceptualization of sport orientations. Meaningful comparisons across sex may be undertaken, since both men and women who are wheelchair basketball athletes perceive the three short-form SOQ factors similarly.

Based on sample-specific validity evidence theory, it was hypothesized that the exploratory and confirmatory factor analyses would yield evidence on validity for wheelchair athletes who were different from able-bodied athletes. Exploratory factor analysis confirmed the hypothesis with a clear fourth and a questionable fifth factor. A confirmatory factor analysis did not adequately explain the new five-factor model. The new emerging fourth and fifth factors separated the competitiveness element of the questionnaire in ‘self-referenced’ and ‘other-referenced’ elements of competitiveness. Results are discussed in terms of demographic characteristics of the sample of wheelchair athletes.

The present study was designed to evaluate the effect of physiotherapy-based breathing retraining on asthma control and on asthma physiological indices across time. A 6-month controlled study was conducted. Adult patients with stable, mild to moderate asthma (n = 40), under the same specialist's care, were randomized either to be trained as one group receiving 12 individual breathing retraining sessions (n = 20), or to have usual asthma care (n = 20). The main outcome was the Asthma Control Test score, with secondary outcomes the end-tidal carbon dioxide, respiratory rate, spirometry, and the scores of Nijmegen Hyperventilation Questionnaire, Medical Research Council scale, and SF-36v2 quality-of-life questionnaire. The 2 × 4 ANOVA showed significant interaction between intervention and time in asthma control (F = 9.03, p < .001, η(2) = 0.19), end-tidal carbon dioxide (p < .001), respiratory rate (p < .001), symptoms of hypocapnia (p = .001), FEV1% predicted (p = .022), and breathlessness disability (p = .023). The 2 × 4 MANOVA showed significant interaction between intervention and time, with respect to the two components of the SF-36v2 (p < .001). Breathing retraining resulted in improvement not only in asthma control but in physiological indices across time as well. Further studies are needed to confirm the benefits of this training in order to help patients with stable asthma achieve the control of their disease.

Up to now, the ACT has not been validated for the Greek asthma patients. The present study was designed to examine the validity and reliability of the ACT responses in Greek asthma outpatients under a specialist's care. Following evidence for sample-specific validity, the ACT (n = 100) was examined through construct, cross-sectional, convergent, and discriminant validity as well as internal consistency and test-retest reliability [root mean squared error of approximation (RMSEA)]. A one-factor solution fit the data [χ(2) (chi-square) = 3.899, df (degrees of freedom) 5, ns, RMSEA <0.001]. The ACT showed a high internal consistency (Cronbach alpha = 0.72) and a high 2 months test-retest reliability (IR = 0.85) for the total sample. Significant differences were found between the five categories of asthma control patients (not controlled at all, poorly controlled, somewhat controlled, well controlled, and completely controlled), according to the specialists' rating, for the ACT (p < .001). Significant differences were found between patients with and without asthma control (p = .001), patients of different gender (p = .05), educational status (p = .05), mean year income (p = .01), body mass index (p = .05), follow-up visits (p = .01), as well as among patients of different age (p < .001) and severity (p < .001). An ACT score of 19 or less provided optimum balance of sensitivity (98.46) and specificity (88.57) for screening 'not controlled' asthma. Cross-sectional validity testing showed moderate correlation of the ACT score with FEV1% predicted (r = 0.57, p < .001) and disability (r = -0.42, p < .001) and moderately high correlation with dyspnea (r = -0.71, p < .001). Convergent validity testing showed that the ACT score was correlated with the specialists' rating (r = 0.89, p < .001). The ACT is valid and reliable in Greek outpatients with asthma under a specialist's care.

In this randomized controlled trial, 22 adolescents (13-19 yrs old) from a special school for children with physical disabilities were randomly allocated to the experimental and control training groups. The experimental training group underwent a treadmill program without body weight support at a comfortable speed. The control group received treatment with conventional physiotherapy, which consisted of three sets of exercises with mat activities, balance, gait training, and functional gross motor activities. The program lasted 12 wks with a frequency of three times per week for both groups. Pretest and posttest measurements of self-selected walking speed, gross motor function, and spasticity were conducted. The analysis of covariance findings examining posttest differences between groups were significant with respect to self-selected walking speed (F = 8.545, P = 0.000) and gross motor function (F = 9.088, P = 0.007), whereas no significance was found for spasticity. Treadmill training may improve the walking speed and gross motor function of adolescents with spastic cerebral palsy, without adverse effects on spasticity.
