TI  - Effects of equal-volume resistance training performed one or two times a week in 
      upper body muscle size and strength of untrained young men.
PG  - 144-9
AB  - AIM: The purpose of the present study was to compare the effects of equal-volume 
      resistance training (RT) performed once or twice a week on muscle mass and 
      strength of the elbow flexors in untrained young men. METHODS: Thirty men (23 +/- 3 
      years) without previous resistance training experience were divided into two 
      groups: Group 1 (G1) trained each muscle group only once a week and group 2 (G2) 
      trained each muscle twice a week during 10 weeks. Baseline and 10 weeks post-test 
      elbow flexors muscle thickness (MT) were measured using a B-Mode ultrasound. Peak 
      torque (PT) was assessed by an isokinetic dynamometer before and after the 
      training program. RESULTS: Elbow flexors MT increased significantly (P<0.05) from 
      31.70 +/- 3.31 to 33.43 +/- 3.46 mm in G1, and from 32.78 +/- 4.03 to 35.09 +/- 3.55 mm 
      in G2. Elbow flexors PT also increased (P<0.05) from 50.77 +/- 9.26 to 54.15 +/- 
      10.79 N.m in G1, and from 48.99 +/- 11.52 to 55.29 +/- 10.24 N.m in G2. The results 
      of ANOVA did not reveal group by time interactions for any variable, indicating 
      no difference between groups for the changes in MT or PT. CONCLUSION: The results 
      from the present study suggest that untrained men experience similar gains in 
      muscle mass and strength with equal volume RT performed one or two days per week.
