- Life satisfaction in young footballers: The contribution of basic needs satisfaction and passionPublication . Braz, Diogo Salgado; Gouveia, Élvio R; Teixeira, Diogo S; Sarmento, Hugo; Monteiro, DiogoThe present study was grounded in Self-Determination Theory and the Dualistic Model of Passion. The objective of the study was to examine the relationships between basic psychological need satisfaction, passion (harmonious and obsessive), and life satisfaction in youth football players. The sample comprised 403 male youth football players aged 13 to 17 years who completed validated self-report measures assessing autonomy, competence, relatedness, passion for football, and global life satisfaction. The structural equation modeling approach was employed to assess direct and indirect associations among variables, as well as to ascertain invariance of the model across age groups. The results of the study indicated that the satisfaction of basic psychological needs was associated with a propensity toward harmonious passion, while concurrently demonstrating an inverse relationship with obsessive passion. The harmonious passion–life satisfaction relationship was found to be positive, while the obsessive passion–life satisfaction relationship was found to be negative. The present study examined the relationship between need satisfaction and life satisfaction, with the hypothesis that passion would mediate this relationship. It was predicted that the way players internalize their motivation would play a central role in translating sport experiences into broader well-being. The structural model demonstrated invariance across age groups, thereby suggesting developmental robustness of these motivational processes throughout adolescence. These findings underscore the significance of need-supportive environments in youth football, which are instrumental in fostering adaptive forms of passion and promoting long-term psychological well-being.
- Quantification of Maximal Force Produced in Standard and Contra-Standard Sculling in Synchronized Swimming. A Pilot StudyPublication . Diogo, V.; Soares, S.; Tourino, C.; Carmo, C.; Aleixo, I.; Morouço, P.; Figueiredo, P.; Vilas-Boas, J. P.; Fernandes, R. J.Studies carried out in synchronized swimming are very scarce, namely those which include biomechanical analysis of the sculling technique. The purpose of this study was to measure the maximal force produced in standard and contra-standard sculling, using a 30s maximal tethered synchronized swimming test. One former female synchronized swimmer and one former female swimmer performed a 2x30s maximum intensity tethered synchronized swimming test, in standard and contra-standard sculling conditions, respectively. Parameters studied were maximal, mean and minimum force, the time when maximal and minimum force occurred, and fatigue index. Results showed that the higher values of maximal and mean force were found in standard sculling, both for the synchronized swimmer and the swimmer. The swimmer attained higher values of absolute and relative maximal force in the standard sculling, but lower values in the contra-standard technique, when compared to the synchronized swimmer. Fatigue Index results evidence that the maximal force declined during the 30s in both participants and in both sculling conditions. This parameter was higher for the contra-standard sculling performed by the swimmer, and for the standard sculling for the synchronized swimmer. In conclusion, there were differences in force production in standard and contra-standard sculling between a swimmer and a synchronized swimming. Those differences could probably be explained by differences in skill competence.
- The relationship between coaches’ interpersonal behaviors, basic psychological needs, behavioral regulation, and intentions towards sport persistencePublication . Monteiro, Diogo; Teixeira, Diogo S.; Morales-Sanchéz, Veronica; Chica-Merino, Encarnación; Matos, Rui; Amaro, Nuno; Antunes, Raul; Jacinto, MiguelThis study investigates the relationships between coaches’ need-supportive and need-thwarting behaviors, satisfaction of basic psychological needs, motivation, intentions to continue, and athletes sport persistence. A total of 518 athletes (212 male, 306 female), 18 to 32 years (M = 23.18, SD = 4.19), participated in the study, with participants from football (n = 179), basketball (n = 166), and swimming (n = 173). A structural equation model and a mediation model were performed to understand the associations between motivational factors based on self-determination theory and a 2-year sport persistence assessment. Intentions to continue sport practice accounted for 12% of the variance related to sport persistence in the structural equation model. The mediation model did not reveal any direct effects for need-supportive or need-thwarting behaviors towards sport persistence. However, significant indirect paths were identified in the bright side of the model. Total indirect effect of the need-supportive behaviors in the model was β = .14 (CI95% = .26, .37) while for need-thwarting behaviors was β = −.05 (CI95% = −.11, −.01) towards sport persistence, indicating a positive mediation process. Coaches by being perceived as need-supportive may increase athletes’ intention to continue participating in sport, and consequently sport persistence.
- Tethered Swimming Can Be Used to Evaluate Force Contribution for Short-Distance Swimming PerformancePublication . Morouço, Pedro G.; Marinho, Daniel A.; Keskinen, Kari L.; Badillo, Juan J.; Marques, Mário C.Morouço, PG, Marinho, DA, Keskinen, KL, Badillo, JJ, and Marques, MC. Tethered swimming can be used to evaluate force contribution for short-distance swimming performance. J Strength Cond Res 28(11): 3093-3099, 2014-The purpose of this study was two-fold: (a) to compare stroke and the physiological responses between maximal tethered and free front crawl swimming and (b) to evaluate the contribution of force exertion for swimming performance over short distances. A total of 34 male swimmers, representing various levels of competitive performance, participated in this study. Each participant was tested in both a 30-second maximal tethered swimming test and a 50-m free swimming test. The tethered force parameters, the swimming speed, stroke (stroke rate [SR]), and the physiological responses (increase in blood lactate concentration [ΔBLa], heart rate, and rate of perceived exertion) were recorded and calculated. The results showed no differences in stroke and the physiological responses between tethered and free swimming, with a high level of agreement for the SR and DBLa. A strong correlation was obtained between the maximum impulse of force per stroke and the speed (r = 0.91; p < 0.001). Multiple regression analysis revealed that the maximum impulse and SR in the tethered condition explained 84% of the free swimming performance. The relationship between the swimming speed and maximum force tended to be nonlinear, whereas linear relationships were observed with the maximum impulse. This study demonstrates that tethered swimming does not significantly alter stroke and the physiological responses compared with free swimming, and that the maximum impulse per stroke should be used to evaluate the balance between force and the ability to effectively apply force during sprint swimming. Consequently, coaches can rely on tethered forces to identify strength deficits and improve swimming performance over short distances.
