Resumo

Objetivou-se investigar as relações do Tempo de Reação Simples (TRS), do Consumo Máximo de Oxigênio (O2máx) e da Potência Máxima Anaeróbica (Pmáx) no desempenho de homens e mulheres, adultos da categoria A, praticantes recreacionais de Orientação. Dezesseis sujeitos (8 homens e 8 mulheres; idade: 30 ± 4 e 27 ± 5 anos; massa corporal 78,8 ± 5,9 e 69,2 ± 10,4 kg; TRS: 1,391 ± 0,19 e 1,317 ± 0,25 ms; O2máx: 67,4 ± 3,22 e 48,5 ± 8,28 ml.kg-1.min-1; Pmáx: 675,0 ± 149,6 e 458,4 ± 88,62 W), foram submetidos a três sessões de avaliação: caracterização amostral (1a sessão); mensurações do TRS - Reaction Time Task v.2.0, do O2máx e da Pmáx - Running Anaerobic Sprint Test (2a sessão); prova de Orientação (3a sessão). Os resultados de comparação (teste T de Students) e de relação (Correlação Linear Produto-Momento de Pearson e Regressão Linear Múltipla) demonstraram relações estatisticamente significativas entre as variáveis independentes e o desempenho. A Pmáx apresentou forte poder de predição no grupo masculino (41%), seguida do TRS (32%) e do O2máx (27%). No grupo feminino, o TRS foi a variável mais preditora (54%), seguida do O2máx (32%) e da Pmáx (12%). Pode-se concluir que o TRS, o O2máx e a Pmáx são variáveis preditoras do desempenho em adultos praticantes recreacionais de Orientação da categoria A. Especificamente, em sujeitos com maiores capacidades cardiorrespiratórias, a Pmáx parece ser a principal variável preditora. Em contrapartida, o TRS passa a ser a variável com maior poder de predição.
