The bandwidth knowledge of results regarding the task of the overhand serve in volleyball

Aim: Motor learning is considered a complex process, providing numerous investigations. Knowledge of Results (KR), kind extrinsic feedback, one the variables that are used for investigations on motor learning. There different ways to provide KR optimize The bandwidth these forms, being factor affects learning, however, specificity task needs be in investigation this theme. Thus, objective study analyze acquisition skills overhand serve volleyball. Methods: sample consisted 24 volunteers both sexes (12 men and 12 women), 18 35 years age (M = 27, SD 3.46) inexperienced task. effect was analyzed two groups (with range without range), which had learn control their force by performing volleyball tennis type service order hit target line. Performance inferred mean standard deviation absolute, constant variable errors. Results: no statistically significant difference between improved precision (absolute error error) consistency (variable during acquisition. an improvement also transfer test measures. Conclusion: similar condition have information at each attempt, causing dependence external information.
