The aim of this study was to investigate the impact protocols equalized by time under tension (TUT) but composed different repetition durations and repetitions numbers on muscle activation blood lactate concentration. Twenty-two males with previous experience in resistance training performed 2 (A B) Smith machine bench press exercise, both 3 sets, minutes' rest, 60% 1 maximum (1RM). Protocol A consisted 6 a 6-second duration for each repetition, whereas B subjects 12 3-second repetition....
Diniz, RCR, Tourino, FD, Lacerda, LT, Martins-Costa, HC, Lanza, MB, Lima, FV, and Chagas, MH. Does the muscle action duration induce different regional hypertrophy in matched resistance training protocols? J Strength Cond Res 36(9): 2371-2380, 2022-The manipulation of (MAD) can influence instantaneous torque along range motion, which lead to adaptations hypertrophy. The aim this study was compare effects (RT) on knee extension machine with MAD cross-sectional area (CSA) responses within...
This study aimed to investigate the bio- mechanical response of hamstring muscles acute stretching in dancers (D) compared non-dancers (ND). Maximal range motion (ROM Max ) and stiffness hamstrings were assessed 46 young males, 23 undergraduate students (ND) professional (D). Ages two groups D 21.5 ± 0.60 years; ND 27.5 0.98 years). Testing was performed sessions, familiarization with procedures first session tests themselves (pre- post-test intervention) second, a 24- 48-hour interval...
The present study investigated the effect of 10-week matched (range motion, volume, intensity, rest, and repetition duration) training protocols with varying muscle action duration (MAD) on maximal voluntary isometric contraction (MVIC) test at eight different knee angles one-repetition maximum (1RM) after in seated extensor machine. Forty women were allocated into one control three groups MAD: 5C1E (5s concentric [CON] 1s eccentric [ECC]), 3C3E (3s CON 3s ECC), 1C5E (1s 5s ECC). All (5C1E,...
This study is aimed at evaluating the profile of inflammatory markers and components redox regulation in untrained women after 10 weeks resistance training using equalized protocols but different muscle action duration (MAD). Twenty-two underwent progressive exercising knee extensor muscles for weeks-3x/week, with 3-5 sets 6 repetitions 50% 1 repetition maximum strength test (1RM), a rest 180 s between series, following protocol (i) 5 concentric eccentric (5C-1E) (ii) (1C-5E). Quadriceps...
Abstract This study investigate the effect of 10-week strenght training on amplitude electromyographic (EMG) signal vastus medialis, lateralis and rectus Femoris. Twenty three untrained volunteers performed 3-5 sets (3 - weeks 1 2; 4 series 3 4; 5 to 10) with 6 repetitions, intensity 50% repetition maximum (1RM), min rest between s duration at knee extensor exercise. One group (5:1) concentric action eccentric other (3:3) s. The VM, VL RF EMG (RMS) activities were recorded in each first...
Aim: The objective of the present study was to compare amplitude electromyographic (EMG) signal quadriceps muscle portions vastus medialis (VM), lateralis (VL) and rectus femoris (RF) activation ratio (VM/VL, VM/RF VL/RF) in protocols with different durations concentric eccentric muscular actions. Material method: Twelve female volunteers performed knee extensor exercise two [1s for action 5s (1:5); 1s (5:1)] 3 sets 6 repetitions, 180s pause between each a intensity 50% 1RM. root mean square...
O objetivo deste estudo foi comparar a concentração de lactato sanguíneo em protocolos treinamento força com diferentes durações das ações musculares no exercício supino.Dezessete voluntários executaram três séries seis repetições 60% 1RM, pausa minutos entre as e (2-4: 2s concêntrica 4s excêntrica; 3-3: 3s 4-2: excêntrica).A análise da considerou os valores médios por série cada protocolo.Os resultados ANOVA twoway mostraram que o efeito principal protocolo não apresentou diferença...
Abstract The purpose of the present study was to examine whether there would be performance differences between external and internal focus attention conditions an online demonstration condition, if these observed at a neuromuscular level through EMG analysis, in addition traditional outcome measures. We hypothesized that under condition participants perform better than conditions. also show smaller activity Furthermore, we hope replicate benefits relation focus, both product Six male...
Objective: To compare the acute effect of two training protocols until concentric failure (CF) with different intra-set interval (ISI) configurations (20 s and 40 s) on total weight, number repetitions, time under tension in trained subjects. Methods: Ten men participated study (age = 25.1 ± 4.4 years; body mass 76.5 10.4 kg; height 175.8 9.3 cm). Two were performed 4 sets bench press exercises differentiated by ISI: i) Protocol ISI-40 (40 - each set consisted 6 repetitions followed an ISI...
