- Biomechanical and bioenergetical evaluation of swimmers using fully-tethered swimming: A qualitative reviewPublication . Amado, Nuno M.; Morouço, Pedro, G.; Marques, Mário C.; Fernandes, Ricardo J.; Marinho, Daniel A.It is presented a qualitative review of the specialized literature on fully-tethered swimming, with the scopes of summarizing and highlighting published knowledge, identifying its gaps and limitations, and motivate future research. The major research conclusions can be summarized as follows: (i) tethered swimming is a reliable test to evaluate force exerted in water by swimmers; (ii) higher maximum values of force are obtained in breaststroke and butterfly, while average values are higher in front crawl; (iii) tethered forces present moderate to strong relationships with swimming velocity, and associations between forces diminish as swimming distance increases; (iv) 30 s maximal tethered swimming may be used as an adaptation of Wingate test for swimming; (v) differences in stroke mechanics can occur in tethered swimming but there is no evidence to suggest that they affect swimming performance; (vi) Tethered swimming is a valid methodology to evaluate aerobic energy contribution in swimming and recent investigations concluded that it can also provide information on the anaerobic contribution. Based on and stimulated by current knowledge, further research should focus on the following topics: (i) the usefulness of tethered swimming as a valid tool to evaluate other swimming techniques; (ii) differences in force parameters induced by gender or competitive level; (iii) defining accurate variables for estimation of anaerobic power and/or capacity using tethered swimming; (iv) bilateral asymmetries in exerted forces, and corresponding influence of breathing; (v) relative contribution of arms and legs for whole-body propelling forces
- The effect of practicing sports on the body composition and physical fitness of people with intellectual and developmental disabilitiesPublication . Oliveira Diz, Susana Cristina; Susano Jacinto, Miguel Ângelo; Costa, Aldo Filipe Matos Moreira Carvalho; Matos, Rui; Monteiro, Diogo; Teixeira, José E.; Antunes, RaulIntroduction: People with IDD tend to have a sedentary lifestyle, which affects their health and physical fitness. Methods: The aim of this study was to analyses the effect of a sport-based intervention, with weekly 60-min sessions over 36 weeks, on the body composition and functional physical fitness of people with Intellectual and Developmental Disabilities (IDD). The sample consisted of 36 institutionalized participants with IDD, divided into two groups: experimental group with 23 participants (M = 37.26; SD = 13.84) and control group with 13 individuals (M = 38.31; SD = 14.22). A stadiometer, bioimpedance equipment and the Hand Grip, Sit and Stand, Timed Up and Go and 6 Min Walk tests were used to assess the variables of interest. Results: The experimental group showed statistically significant values in body mass index (p = 0.01; r = 0.301), muscle mass (p < 0.01; r = 0.431), Sit and Stand Test (p = 0.01; r = 0.324) and 6 Min Walk Test (p < 0.01; r = 0.399). Discussion: The results suggest that long-term programs based on the practice of sports can bring benefits to the body composition and functional physical fitness of adults with IDD.
- Effects of dry-land strength training on swimming performance: a brief reviewPublication . Morouço, Pedro; Marinho, Daniel Almeida; Amaro, Nuno; Pérez-Turpin, José Antonio; Marques, Mário CardosoMorouço PG, Marinho DA, Amaro NM, Peréz-Turpin JA, Marques MC. Effects of dry-land strength training on swimming performance: a brief review. J. Hum. Sport Exerc. Vol. 7, No. 2, pp. 553-559, 2012. This article provides a brief review over the state of art concerning dry-land training for swimmers. It is important to understand the role of muscular strength for swimming performance and how it might be improved. Firstly, this article analyzes the relationships between strength or power assessment in dry-land and swimming performance. Secondly, the results of studies aiming to evaluate the influence of dry-land strength training to swimming performance improvement are presented. These results allow coaches to realize the benefits that may be obtained by an appropriate strength training program, according to gender and level.
- 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.
