Frequency of resistance training does not affect inhibitory control or improve strength in well-trained young adults

Abstract

The objective of the current study was to compare the effects of resistance training frequency on cognitive inhibitory control in young adults with previous experience in the modality. Male participants (N = 36) were randomly placed into one of three experimental groups. Participants performed resistance training 1 (F1), 2 (F2), and 3 (F3) times per week for 24 weeks. The three groups performed exercises of equal intensity, volume-load, and rest duration. Cognitive inhibitory control (via Stroop test) was tested 72 h before (pre-experiment) and 72 h after (post-experiment) the resistance training program. No time vs. group interaction effects were noted for accuracy (F(4, 29) = 3.57, p = 0.18) or response time (F(4, 29) = 2.61, p = 0.06) on the Stroop test. These results indicate that increased resistance training frequency, when volume-load is kept constant, does not appear to potentiate cognitive inhibitory control.

Effect of different training frequencies on maximal strength performance and muscle hypertrophy in trained individuals—a within-subject design

“…Differently from the McLester Jr. et al [ 35 ], that estimated muscle mass increase and body composition alterations through skinfold measurements, most recent studies performed these same measurements through dual-energy x-ray absorptiometry [ 38 , 39 , 42 , 45 ], air displacement plethysmography [ 46 ], and ultrasound images [ 22 , 37 , 39 – 41 , 43 , 44 , 46 ]. In many of these studies [ 22 , 39 – 41 , 44 , 46 ] authors did not find differences in lower limbs muscle CSA when different RT frequencies were compared.…”
