- Proposta metodológica para a aquisição da viragem de crolPublication . Lopes, Hugo; Louro, Hugo; Martins, Marta; Moreira, António; Conceição, Ana; Louro, HugoSegundo Fernandes & Vilas-Boas (2001), o tempo total de uma prova divide-se pelos parciais: de tempo de partida; tempo de nado; tempo de viragem. Este último pode ser dividido em tempo de aproximação à parede, tempo de rotação e tempo de reinício de nado, pelo que deve ocorrer até aos 15m (Sanders, 2002). A sua execução técnica tem vindo a mudar e a evoluir ao longo dos tempos, e de acordo com Lyttle & Benjanuvatra (2004), alguns ajustes na viragem pode se traduzir em melhorias substanciais no tempo final da prova. Existem estudos que comprovam que pequenos ajustes podem melhorar 0.20s por volta (Maglischo, 2003). De modo a que o processo de ensino/aprendizagem seja o mais ajustado e coerente, é necessário definir conjunto de progressões pedagógicas devidamente orientadas. Esta proposta será composta pelos parâmetros: aprendizagem do rolamento, rolamento com apoio, rolamentos sem apoio; impulsão, deslizes, impulsão e deslizes, deslizes com rotações e pernadas; aproximação à parede. Tem como base o equilíbrio durante o rolamento de forma a que a aprendizagem seja simples, neste sentido, requer a aquisição do rolamento bem adquirido e consolidado para prosseguir para as etapas seguintes da aquisição técnica. Ao contrário da metodologia tradicional do ensino da viragem a partir da aproximação, rolamento, impulsão/deslize esta proposta metodológica pretende facilitar a aprendizagem e o ensino da viragem de crol, através primeiramente da aquisição consolidada do rolamento e deslize e depois com a aproximação à parede.
- The effects of detraining on lower force and maximum aerobic power in pre-pubescent football athletesPublication . Brito, João Paulo; Jacinto, J.; Fernandes, Renato; Louro, Hugo; Conceição, AnaOBJECTIVE Detraining results in the loss of cardiovascular and metabolic characteristics and consequently results in the reduction of VO2max and muscular strength (Coyle, 1994, Evangelista & Brum, 1999). For most researchers the VO2max is an indicator of greater fidelity in the characterization of aerobic power of an individual, as well as their level of fitness (1,2,3,4,5,6). Because detraining in young athletes has received little attention, is important to discuss this area. In adults, training-induced increases in muscle strength and VO2max appear to decline during detraining about and in the same rate as they increase during training. To date, only one study (Blimkie et al., 1989) looked at the effects of 8 weeks of detraining in prepubertal boys following 20 weeks of resistance training. The training-induced strength gains regressed towards the growth-adjusted control level during the detraining period, suggesting that alike with adults, training adaptations are reversible (Blimkie et al., 1989). The aim of this study was to know the effect of detraining in a period of 34 days on the Maximum Aerobic Power (MAP) and Lower Force (LF), in pre-pubescent children football players. METHODS Eight pre-pubescent male football players (age 12.75 ± 0.71years; weight 41.46 ± 6.66 kg; height 1,51 ± 0.06 cm; BMI 19,30 ± 3,59) were assessed before and after 5 weeks of a detraining period. A Modified Balke maximal protocol using ergo-spirometry procedures (Cosmed® K4b2) was selected to determine VO2max and the Ventilatory Anaerobic Threshold (VAT) as estimates for the aerobic capacity. To access the LF a Coutermovement Jump (CMJ) was made in the Ergojump®. Data comparisons were set to determine the relationships between the parameters resulting from testing. RESULTS The MAP (VO2max/kg) show a significant difference from the pre vs post detraining period (69,27 ± 5,41 ml.kg.min-1 vs 63,22 ± 4,95 ml.kg.min-1, p=0,002) however the LF doesn’t report significant changes. DISCUSSION & CONCLUSION The results suggest that 5 weeks of detraining decrease the MAP (VO2max/kg) of pre-pubescent football players although not significant changes were report on the LS parameter.
- Evaluation of the effects of a walking programme in the fall risk factors in the older people: balance, strength and agility – longitudinal pilot studyPublication . Monteiro, Lina; Ramalho, F; Santos-Rocha, Rita; Morgado, Sónia; Bento, TeresaBackground Falls are the main reason for the high mortality and morbidity rate among older people, and are the main cause of immobility and autonomy loss. Walking programmes are a positive way of preventing falls on apparently healthy elders. Objective: The objective of this study was to analyse the effects of a walking programme on the fall risk factors of older people, namely, the strength, balance and agility. Methods Five elders (63 and 83 years old) integrated an experimental group that participated in a weekly walking activity supervised by an exercise specialist for a sixty minutes’ period, throughout a nine months’ period. The evaluations took place in three moments, consisting of functional fitness and physical activity tests. Results Results showed an increase in the vigorous activity score, walking score, movement score and standing position score between the first and the second moment of evaluation. There was as also a significant decrease in the sitting position score, which confirmed the decrease in the sedentary behaviour of the participants. The pedometer showed us a significant increase of steps, between the two moments, and the variable related to walking, indicated positive average results in the longitudinal evaluation (0.026 ≤ 0.05). Conclusions The walking programme induced positive results in some of the fall risk factors in the older people, such as physical activity and cardiorespiratory fitness, therefore we believe that the quality of life of the participants was improved. Finally, the observed decreased in sedentary behaviour can be an important message for interventions with walking activity.
- Results from a 9-month physical activity intervention in physical fitness of older womenPublication . Bento, Teresa; Azul, Joana; Santos-Rocha, RitaObjective: The main purpose of our study was to analyze the effects of a 9-month, physical activity intervention program in physical fitness in older women. Methods: Older women were recruited and randomly assigned to a supervised physical activity group or to a control group. Combined exercise sessions were performed three times a week, for 45 minutes and controlled for intensity. Sociodemographic data, health and daily habits, and physical function was assessed at baseline and after nine months. Results: However the intervention group showed better results at the end of the program, comparison between groups revealed no statistically meaning differences, for all studied variables. Baseline results from both groups revealed to be higher than the reference standards for their age and gender, meaning that participants were already very active at the beginning of the intervention. Not controlling for physical activity in the control group may have limited the analysis. Conclusions: Although not statistically significant, our results indicate that participants of the intervention group achieved better results, meaning that this supervised, community based physical activity intervention program was beneficial. It should also be acknowledge that participants, at least, maintained their initial high level, meaning that there was no decline in their physical function.
- The basic foundations of Capoeira learning from 5 to 10 years of age: implementation and evaluation of a formative projectPublication . Barros, Nelson; Branco, Marco A. C.; Catela, DavidCapoeira differs from the vast majority of other duels by the musical accompaniment, where the rhythm gives the temporal structure to the movement. The practice of Capoeira enables the development of structural elements of human movement, particularly in perception‐action cycles, e.g., music rhythm and specific movements or peripheral vision and attack and defense actions, integrated in cultural and socio‐affective dimensions (Silva & Damiani, 2005). The training in Capoeira follows a traditional course in associations or Capoeira groups where transmission of knowledge is made by the Mestre de Capoeira, each developing an individual philosophy and methodology and based on accumulated practical knowledge. Actually, there is no formal process and specific training of these professionals, and professionals usually have little qualification. The practitioner student passes to teacher condition by subjective criteria (Heine, Carbinatto, & Nunomura, 2009). In order to contribute to a tested contents’ systematization, for the motor learning of the basis of Capoeira, in the 2nd childhood, considered the critical period of development of motor skills and coordinative abilities (Mitra & Mogos, 1990), as well as structuring modes social interaction (Ré, 2011), the authors started a project to build and test a guiding program for Capoeira teaching agents, for them to structure and sustain the progression of learning the basic techniques, tactics and rules; as well as to introduce to the process of interaction between capoeiristas performers and instrumentalists, while respecting the cultural and historical values of Capoeira’ identity.
