| Abstract: | Abstract The effect of one and three coactors on an individual's performance of a muscular endurance task was determined for 8-, 13-, and 18-year-old males. Subjects extended the dominant leg in a horizontal position for as long as possible under one of three conditions: alone, in pairs, and in groups of four. Results showed that individuals in quadrads performed significantly better than individuals in dyads and alone. No significant difference was found between individuals performing alone and in dyads. Eight-year-olds were found to be superior to the two older age groups, but the age factor was independent of the coaction effect. |
