- Career termination of portuguese elite football players: comparison between the last three decadesPublication . Carapinheira, António; Mendes, Pedro; Carvalho, Pedro Guedes de; Torregrossa, Miquel; Travassos, BrunoThe aim of this study was to explore the process of career termination of elite soccer players, comparing the quality and the resources to support career termination over the last three decades. To this end, was developed a questionnaire defined by four sections: (a) biographical data, (b) athletic career, (c) quality of career termination and (d) available resources at the moment of career termination. Ninety male former elite Portuguese soccer players participated in this study. The results highlighted a decrease in the length of athletic career as football players and an increase in the number of years as youth players over the last 30 years. The results also revealed that the quality of career termination was difficult. The analysis of resources for career termination revealed an increase in a high level of education over the years. Despite the evolution in the level athletes' education in the last three decades, the athletic career termination remained difficult and it was reported that they did not plan their career termination. In line with previous studies, the results highlight that the lack of plans for career termination is one of the most important factors that constrain the quality of career transition.
- Correlations between biomechanical variables and sprint time of 30mPublication . Gil, Maria Helena Gonçalves; Marques, MC; Neiva, Henrique; Mendes, Pedro; Sousa, António; Alves, Ana Ruivo; Branquinho, Luís; Faíl, Luís Brandão; Pinto, Diogo; Marques, Diogo; Graça, Cláudia; Marinho, DanielIntroduction: Sprinting contributes to successful performance in the wide range of sporting activities. It’s known that sprinting speed is defined with the frequency and the length of strides (Čoh, Tomažin & Rausavljević, 2007). According Bezodias et al. (2008) the frequency of stride (FS) was a more important contributor to the velocity increase in sprint performance, however for Mackala (2007) the length of stride (LS) was a more significant variable. The aim of this study is to determine if different types of heating can interfere with the frequency and length variability of the stride. Methods: 22 young men participated in this study (age: 19.32±1.43 years; height: 176±67cm; weight: 68.48±9.91kg). The study followed a randomized protocol and the subjects were submitted to three warm-up protocols: without warm-up, typical warm-up and warm-up with post-activation potentiation (PAP). Results: The results reveal a strong correlations between the sprint time of 30m and the frequency of stride and length of stride. Discussion: Regardless of the type of warm-up, we can observe that the frequency and length stride are relevant factors that contribute to sprint time performance. The results corroborated with other studies indicating that maximum speed results from an optimal ratio between stride frequency and stride length. Conclusion: The frequency and length of stride were shown to be two influential factors in the sprint time of 30m. We suggest that future studies include exercises on warm-up that stimulate the frequency and amplitude of stride, in order to verify which of the variables has the greatest impact on sprint performance.
- Imagery ability in Boccia: Comparison among federate athletes from different medical sport groupsPublication . Amorim, André Jorge Pinto; Travassos, Bruno; Mendes, PedroThe aim of this study was to analyse and compare movement visualization ability in federate and non-federate Boccia athletes, and among federate Boccia medical sport groups. Forty-two Boccia athletes (Federate N = 24; Non-federate N = 18) at an average age of 35.8 (SD = 11.19) participated in this study. The Portuguese version of Movement Imagery Questionnaire - 3 (MIQ-3), was used for this study. The participants were evaluated on the internal and external visual imagery. Statistics was carried out following the method of interference based on the magnitude of the effects. Results showed a great effect of expertise in imagery ability. The comparison between federate and non-federate Boccia athletes showed a great effect in the Internal Visual subscale and a moderate effect in the External Visual subscale. It was also observed differences between athletes from different medical-sports groups, revealing that the requirements of the sport linked to their action abilities provides them with different Imagery abilities. These results clearly influence the prescription of imagery training programs for different groups taking into account different medical-practice groups.
- Sports career termination in football players: systematic reviewPublication . Carapinheira, António; Mendes, Pedro; Carvalho, Pedro Guedes de; Travassos, BrunoThis article aimed to characterize the termination of the sports career in football players. A systematic literature search was performed according to the PRISMA method. From all the publications, eight were selected that fulfilled all the inclusion criteria. The results revealed that, in general, the former football players finish their career between the ages of 31 and 35, reported a career span between eight and eleven years, and secondary education level. Regarding the quality of retirement, it was reported that voluntary retirement was mainly due to age and associated with psychological and social problems. Few data were reported regarding the available resources, highlighting, however, coping strategies through support from family and friends, and players maintain a career linked to sports. Only one study revealed the existence of a program to support the retirement of a sports career. © 2018, Facultad de Formacion del Profesorado.
