BACKGROUND: Some authors suggest that single joint (SJ) exercises promote greater muscle @entity1184 because they are easier to be learned and therefore have less reliance on neural factors. On the other hand, some authors recommend an emphasis on @entity2720 ( @entity2720 ) exercises for maximizing muscle strength, assuming that @entity2720 exercises are more effective than SJ exercises because they enable a greater magnitude of weight to be lifted. OBJECTIVES: The present study aimed to compare the effects of @entity2720 vs. SJ exercises on muscle size and strength gains in untrained young @entity1 . @entity1 AND METHODS: Twenty-nine young @entity1 , without prior resistance training experience, were randomly divided into two groups. One group performed (n = 14) only @entity2720 exercises involving the elbow flexors (lat. pull downs), while the other (n = 15) trained the elbow flexors muscles using only SJ exercises (biceps curls). Both groups trained twice a week for a period of ten weeks. The volunteers were evaluated for peak torque of elbow flexors (PT) in an isokinetic dynamometer and for @entity121 ( @entity121 ) by ultrasonography. RESULTS: There were significant increases in @entity121 of 6.10% and 5.83% for @entity2720 and SJ, respectively; and there were also significant increases in PT for @entity2720 (10.40%) and SJ (11.87%). However, the results showed no difference between groups pre or post training for @entity121 or PT. CONCLUSIONS: In conclusion, the results of the present study suggest that @entity2720 and SJ exercises are equally effective for promoting increases in upper body muscle strength and size in untrained @entity1 . Therefore, the selection between SJ and @entity2720 exercises should be based on individual and practical aspects, such as, equipment availability, movement specificity, individual preferences and time commitment.
