Objective:The aim of this study was to evaluate physical conditioning and muscle strength before and after a four-month program of physical training. Methods: Two groups of children, ages 8 to 11 years, with moderate asthma were studied. All subjects were tested before and after a program of physical training, which was conducted in 90-min sessions, twice weekly, for four months and also included exercises performed in the water. Children in both groups received general information about asthma, as well as information about the management and treatment of asthma. Results: In the final evaluation, anthropometric parameters (height and weight) were found to have increased. Children in the exercise group presented significant gains in the distance run in nine minutes (initial 1.333 + 0.03 km vs. final 1.440 + 0.03 km; p < 0.05), number of abdominal crunches (initial 24.3 + 1.4 abdominais vs. final 33.2 + 1.1; p < 0.05), maximal inspiratory pressure (initial 73 + 5 cmH 2 O vs. final 103 + 5 cmH 2 O; p < 0.05), maximal expiratory pressure (initial 75 + 4 cmH 2 O vs. final 102 + 4 cmH 2 O; p < 0.05) and heart rate at rest (initial 84.3 + 1.6 bpm vs. final 77.1 + 2.7 bpm; p < 0.05). The control group presented no significant changes in any of these parameters. Conclusion: An exercise program involving longer sessions, conducted less frequently, facilitates increased participation by children, thereby leading to better physical conditioning and greater muscle strength.

ResumoObjetivo: Investigar a influência da dominância de membros sobre o desempenho dos membros inferiores em testes funcionais. Métodos: Oito atletas recreacionais (20,702,19 anos; 75,9015,30 kg; 1,730,07 m), de ambos os sexos, fizeram parte deste estudo-piloto. O desempenho funcional dos membros inferiores foi avaliado por meio de três testes de salto unipodal: hop test (HP), six-meter timed hop test (STHT) e square hop test (SHT), sendo considerado, em cada teste, o desempenho médio de três tentativas válidas, para a análise dos dados. Resultados: De acordo com o teste t-Student para amostras dependentes (=5%), não houve diferença significativa entre o desempenho dos membros dominante e não-dominante, nos três testes funcionais: HT (p=0,27), STHT (p=0,70) e SHT (p=0,23). Conclusão: A dominância de membros inferiores parece não influenciar de forma decisiva o desempenho funcional de atletas recreacionais.Palavras-Chave: dominância cerebral, membros inferiores, avaliação do desempenho. AbstractObjective: To investigate the influence of limb dominance on lower limb performance in functional tests. Methods: Eight recreational athletes (20.702.19 years, 75.9015.30 kg, 1.730.07 m), of both sexes, were took part of this pilot-study. The lower limb functional performance was evaluated by means of three single-leg hop tests: hop test (HP), six-meter timed hop test (STHT) and square hop test (SHT). Each test considered the average performance of three valid attempts to data analyzes. Results: According to the Student's t-test for dependent samples (= 5%), there was no significant difference between dominant and non-dominant limbs performance in the three functional tests: HT (p= 0.27), STHT (p= 0.70) and SHT (p= 0.23). Conclusion: The lower limb dominance does not seem to influence decisively the functional performance of recreational athletes.
