Increased fascicle length but not patellar tendon stiffness after accentuated eccentric-load strength training in already-trained men
Purpose This study examined whether additional external load during the eccentric phase of lower limb strength training exercises led to greater adaptations in knee extensor strength, muscle architecture, and patellar tendon properties than traditional concentric–eccentric training in already-trained men. Methods Twenty-eight men accustomed to strength training were randomized to undertake 10 weeks of supervised traditional (TRAD) or accentuated eccentric loading (AEL) or continue their habitual unsupervised (CON) strength training. TRAD and AEL trained 2∙week−1 with a six-repetition maximum (RM) session and a ten-RM session. TRAD used the same external load in both concentric and eccentric…
Dataset for: ACUTE ELEVATIONS IN SERUM HORMONES ARE ATTENUATED AFTER CHRONIC TRAINING WITH TRADITIONAL ISOINERTIAL BUT NOT ACCENTUATED ECCENTRIC LOADS IN STRENGTH-TRAINED MEN
It has been proposed that the maintenance of acute hormonal responses reveal an efficacy of a training stimulus to evoke ongoing increases in strength and muscle mass. We previously observed that maximum strength continued to improve throughout a 10-week period in an accentuated eccentric loading group (AEL) but not a traditional isoinertial loading (ISO) group. Therefore, the present study investigated whether the magnitude of acute hormonal responses was greater (i.e. maintained) in AEL compared to ISO at the end of the training period. Subjects in AEL (eccentric load = concentric load + 40%) and ISO performed experimental loading tests (3 sets of 10 repetitions in the leg press and knee …
