RESUMO Análise de prova é um procedimento avaliativo comumente utilizado em natação pura, mas que não foi ainda aplicado em nadadores com síndrome de Down. Nesse sentido, foram avaliados nadadores masculinos e femininos síndrome de Down relativamente ao tempo final de prova, velocidade de nado, frequência e distância de ciclo, e velocidade de partida, viragem e chegada, tendo sido relacionadas todas as variáveis e caracterizada a tática de uma prova de meio-fundo. As eliminatórias e finais dos 50, 100 e 200m livres dos 5.º Campeonatos do Mundo de Natação DSISO'2010 as e as finais dos 400m livres dos 6.º Campeonatos do Mundo de Natação DSISO'2012 foram filmadas, observando-se que: (a) os nadadores foram mais rápidos que as nadadoras, apresentando maiores distâncias de ciclo para frequências gestuais semelhantes; (b) os nadadores com síndrome de Down foram mais lentos que os nadadores sem deficiência e com deficiência mínima elegível nos 400m livres; (c) as estratégias de nado mais utilizadas nos 400m livres foram as de início rápido e negative pacing, tendo os nadadores mais rápidos utilizado a estratégia parabólica. Os nadadores com síndrome de Down foram mais rápidos que as nadadoras e atingiramm maiores distâncias de ciclo, enquanto as nadadoras apresentaram maiores dificuldades nas fases de partida, viragens e chegadas. Dos dados obtidos parece não existir vantagem na utilização de uma estratégia especifica de ritmo de prova.

METHODS: Twenty three (12 trained, 11 control) recreational female athletes had lower extremity muscle electromyography (EMG) data quantified during 10 single-leg land-and-cut trials before (Base), immediately (Post 0), and six weeks (Post 6) after a six-week NTP. Surface EMG electrodes were secured over the muscle bellies of the medial (MH) and lateral hamstrings (LH), vastus lateralis (VL), vastus medialis (VM), rectus femoris (RF), and medial (MG) and lateral gastrocnemius (LG) of the dominant limb. The average RMS amplitudes were calculated for each muscle during two jump landing phases; 100 ms prior to ground contact (Pre) and ground contact to 50% of stance (Re). Pre and Re co-contraction indices were also quantified for thigh muscle pairs (VL-LH and VM-MH). Subject based means of the dependent variables were submitted to two-way repeated measures (time) ANOVAs to test for the main and interaction effects of time and group. RESULTS: Subjects demonstrated significantly (p < 0.05) greater Pre and Re LH and MH muscle activation, Re LG muscle activation, and Pre and Re VL-LH and VM-MH co-contraction at both Post 0 and Post 6 time points. Increases in Pre VM (p = 0.014) and Re MG (p = 0.006) activation were only noted at the Post 6 follow-up. CONCLUSION: Lower extremity muscle activation increased during dynamic single-leg landings following a 6-week NTP. Specifically, females increased hamstring and gastrocnemius activation magnitudes, and relative activation of the hamstrings to quadriceps, which may reduce ACL injury risk. Importantly, these beneficial adaptations may even be retained six weeks following training.

The purpose here was to assess its reliability and accuracy when analysing spatial–temporal gait parameters. Forty-two young adults performed 3 × 400 m walking at moderate intensity on a 400-m standard track, using both the WalkinSense and a pedometer. The between-trial reliability was excellent for all variables, with intraclass correlation coefficient values ranging from 0.90 to 0.98. The absolute and percentage differences between the WalkinSense and the track length were (mean ± standard deviation) −36.7 ± 45.0 m (95% confidence interval: −44.6, 28.6) and 9.2 ± 11.3% (95% confidence interval: −11.2, 7.2), respectively. The absolute and percentage differences between the WalkinSense and the pedometer for number of strides were 0.7 ± 10.5 strides (95% confidence interval: −1.2, 2.6) and 0.1 ± 4.0% (95% confidence interval: −0.7, 0.8), respectively. The WalkinSense system showed excellent reliability ...
