Relationship of aerobic and anaerobic parameters with 400 m front crawl swimming performance
The aims of the present study were to investigate the relationship of aerobic and anaerobic parameters with 400 m performance, and establish which variable better explains long distance performance in swimming. Twenty-two swimmers (19.1±1.5 years, height 173.9±10.0 cm, body mass 7l.2±10.2 kg; 76.6±5.3% of 400 m world record) underwent a lactate minimum test to determine lactate minimum speed (LMS) (i.e., aerobic capacity index). Moreover, the swimmers performed a 400 m maximal effort to determine mean speed (S400m), peak oxygen uptake (VO2PEAK) and total anaerobic contribution (CAM). The CAM was assumed as the sum of alactic and lactic contributions. Physiological parameters of 400 m were determined using the backward extrapolation technique (VO2PEAK,<and alactic contributions of CANA) and blood lactate concentration analysis (lactic anaerobic contributions of CANA). The Pearson correlation test and backward multiple regression analysis were used to verify the possible correlations between the physiological indices (predictor factors) and S400m (independent variable) (p<0.05). Values are presented as mean 1 standard deviation. Significant correlations were observed between S400m (l.4±0.1 ms-1) and LMS (1.3±0.1 m.s-1; r=0.80), VO2PEAK (4.5±3.9 L.min-1; r=0.72) and CANA (4.7±1.5 L•O2; r= 0.44). The best model constructed using multiple regression analysis demonstrated that LMS and VOQPEAK explained 85% of the 400 m performance variance. When backward multiple regression analysis was performed, CANA lost significance. Thus, the results demonstrated that both aerobic parameters (capacity and power) can be used to predict 400 m swimming performance
Diagnósticos, resultados e intervenções de enfermagem para crianças na ClÃnica Pediátrica de um hospital escola
Pesquisa exploratório-descritiva, desenvolvida com os objetivos de construir afirmativas de diagnósticos, resultados e intervenções de enfermagem para crianças internadas na ClÃnica Pediátrica de um hospital escola, tendo como base o Banco de Termos da Linguagem Especial de Enfermagem da referida ClÃnica Pediátrica e a CIPE® Versão 1.0; e de validar as afirmativas construÃdas com a participação de enfermeiros experts. Foram elaboradas 107 afirmativas de diagnósticos / resultados de enfermagem, das quais 48 atingiram IC >0.8 (44,85%) entre os enfermeiros experts, no processo de validação. Para estas 48 afirmativas, foram elaboradas 330 intervenções de enfermagem, das quais 270 alcançaram IC >0.8 (81,81%) entre os enfermeiros experts. Acredita-se que a utilização dessas afirmativas poderá representar um relevante instrumento no processo de sistematização da assistência de enfermagem na ClÃnica Pediátrica do hospital escola
