摘要：This study compared two lower body leg lifts, the trap bar deadlift (TBDL) and the leg press (LP), relative to their contributions to strength (6-RM leg strength), power (vertical jump-VJ height), and speed (36.6 meter-36.6MS) in adolescent males. Adolescent males (n=51; 13-15 years) were separated into two groups (TBDL group and LP group) via a matched pair design based on initial VJ height. Periodized resistance training was performed for 8-weeks (2x/wk) and focused on the primary exercises of the TBDL or the LP with supplemental lower body resistance training exercises (lunges, hamstring curls, calf raises, etc.) held equal between the study groups. Pre- and post-tests were conducted for 6-RM leg strength in TBDL or LP, VJ height, and 36.6MS. Both groups improved their lower body leg strength. The TBDL group improved the TBDL 6-RM by 21% (p
