The Effect Of Repetition Tempo On Training Volume, Heart Rate, Blood Lactate, And Muscle Oxygenation When Time Under Tension Is Matched In Recreationally-Trained Lifters, Zachary A. Mang

Health, Exercise, and Sports Sciences ETDs

It is commonly reported that resistance training (RT) with slower-repetition tempos leads to greater metabolic stress because they increase the time under tension (TUT) during sets of exercise. However, little information is available on the effect of different repetition tempos on blood lactate concentration, muscle oxygenation, and heart rate (HR) when TUT and proximity to concentric muscular failure are matched during lower-body RT. In a repeated-measures, cross- over design, 11 recreationally-trained females (n = 5) and males (n = 6) performed five sets of belt squat under the following conditions: Slow-repetition tempo (SLOW; 10 reps with 4:2 second tempo) and …
