The aim of this study was to compare the effects of two types of resistance training on triceps brachial thickness and its connection with maximum strength. The statistical sample included 30 novice bodybuilders who were divided into three groups (each group 10 subjects): experimental group I (pyramidal training), experimental group II (flat pyramidal training)and control group. Both experimental groups took part in protocols of strength training (split method) for eight weeks and six sessions every week. The subjects of control group had their traditional training. The muscle strength and the triceps brachial thickness in three groups were measured before and after the training period. Paired-sample t test and one-way ANOVA were used to determine intergroup differences (P≤0.05) and Pearson correlation coefficient was applied determine the relationships of variables. The observations showed that the anterior-posterior (AP) diameter of the triceps brachial in both experimental groups increased (P<0.01) and (P<0.05) respectively compared with the control group. Also, muscle strength in extension move in both experimental groups increased (P<0.00) and (P<0.04) respectively in comparison with the control group. But, no significant differences were observed between the two experimental groups (I and II) in strength and size of triceps brachial.
