VBRT is classified as resistance training in which \nmovement velocity is used as a depended variable in quantifying the training load (intensity, volume, \ne.g.). An important application of VBRT is quantifying the optimal number of repetitions per set to target \nto specific training adaptations by using the velocity loss within the set as a determinant. The purpose of \nthis study was to compare neuromuscular effects of two different, 20 and 40 %, within set velocity loss \nresistance programs (VL20 and VL40) in lower and upper body in young men and women. \nMethods: The study included a one-week control period and thereafter an 8-week training intervention \nconsisting 15 training sessions. Measurements were made in four testing sessions: Control, Pre, Mid and \nPost. 24 healthy young men (aged 26.4 \u00b1 3.9 years) and 25 women (aged 25.5 \u00b1 3.8 years) were assigned \nto 4 different groups: VL20M = 20 % velocity loss men (n=12), VL40M = 40 % velocity loss men (n=12), \nVL20W = 20 % velocity loss women (n=13) and VL40W = 40 % velocity loss women (n=12). The \ntraining program consisted two exercises: Smith machine full back squat (BS) and Smith machine bench \npress (BP). During the training program, all the repetitions were performed with the maximal initial \nvelocity in every training session and the training intensity and the number of repetitions per each set were \ndetermined by using the velocity-based approach. Both VL20 groups continued performing their exercise \nsets until they reached the within-set mean propulsive velocity (MPV) loss of 20 % and both VL40 until \nthe MPV loss of 40 %. The following neuromuscular measurements were performed: 1RMs in BS and \nBP, mean MPVs against high and low submaximal loads in BS and BP, countermovement jump (CMJ), \nsquat jump (SJ), maximal isometric leg press force (ILP Fmax), maximal isometric bench press force (IBP \nFmax), rate of force development (RFD) in ILP, average force during 0-100 ms (F100ms) in ILP, integrated \nelectromyography (IEMG) during 500-1500 ms in ILP and during the concentric phase in CMJ as well as \nvastus lateralis (VL) cross-sectional area (CSA). \nResults: Significant (p<0.05) increases in BS and BP 1RMs (mean 7\u201310 %) were observed in both groups \nin men. VL20M and VL40M also showed significant increases (p<0.05) in VL CSA at Post (mean 15\u201320 \n%), and in BS and BP MPV against high and low loads at Post (mean 0.04\u20130.17 m/s), except in VL40M \nBP MPV against low loads the change was not significant. No significant between group differences were \nobserved between VL20M and VL40M in any of the variables at any measurement point. Significantly \nhigher (p<0.05) increases were observed from Pre to Post in BS MPV against low loads (0.19 vs 0.14 \nm/s) and BP MPV against high loads (0.14 vs 0.09 m/s) in VL40W than in VL20W. In turn, significantly \n(p<0.05) higher increases from Pre to Post were observed in RFD (32.4 vs 0.7 %) in ILP and VL+VM \nIEMG during CMJ (38.5 vs 12.4 %) in VL20W than in VL40W. \nConclusions: Similar adaptations took place in men to both training programs. Women increased their \ndynamic performance more using VL40 training than VL20 training. Whereas, in explosive isometric \nperformance and muscle activation the VL20 training program led to higher gains in women. The different \nneuromuscular responses to VL20 and VL40 training between sexes in the present study indicate that \nvelocity-based training programs should be designed differently for men and women.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2019-06-18T08:23:26Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2019-06-18T08:23:26Z (GMT).
