The purpose of this study was to investigate the effects of a six-week (16-17 training sessions) low velocity resistance training program (LV) on various performance measures as compared to a traditional strength (TS) and a traditional muscular endurance (TE) resistance training program. Thirty-four healthy adult females (21.1 +/- 2.7 y) were randomly divided into 4 groups: control (C), TS, TE, and LV. Workouts consisted of 3 exercises: leg press (LP), back squat (SQ), and knee extension (KE). Each subject was pre- and posttested for 1 repetition maximum (1RM), muscular endurance, maximal oxygen consumption (VO2max), muscular power, and body composition. After the pretesting, TS, TE, and LV groups attended a minimum of 16 out of 17 training sessions in which the LP, SQ, and KE were performed to fatigue for each of 3 sets. For each training session, TS trained at 6-10 RM and TE trained at 20-30 RM both with 1-2 second concentric/1-2 second eccentric; and LV trained at 6-10 RM, with 10 second concentric/4 s eccentric. Statistical significance was determined at an alpha level of 0.05. LV increased relative LP and KE 1 RM, but the percent increase was smaller than TS, and not different from C in the SQ. For muscular endurance, LV improved similarly to TE for LP and less than TS and TE for KE. Body composition improved for all groups including C (significant main effect). In conclusion, muscular strength improved with LV training however, TS showed a larger improvement. Muscular endurance improved with LV training, but not above what TE or TS demonstrated. For all other variables, there were no significant improvements for LV beyond what C demonstrated.
本研究的目的是调查与传统力量训练（TS）和传统肌肉耐力训练（TE）计划相比，为期六周（16 - 17次训练课程）的低速阻力训练计划（LV）对各种性能指标的影响。34名健康成年女性（21.1 +/- 2.7岁）被随机分为4组：对照组（C）、TS组、TE组和LV组。训练包括3项练习：腿举（LP）、后深蹲（SQ）和伸膝（KE）。对每位受试者进行了1次最大重复量（1RM）、肌肉耐力、最大耗氧量（VO2max）、肌肉力量和身体成分的前后测试。预测试后，TS组、TE组和LV组在17次训练课程中至少参加了16次，其中LP、SQ和KE每项进行3组直至疲劳。对于每次训练课程，TS组以6 - 10RM进行训练，TE组以20 - 30RM进行训练，均采用1 - 2秒的向心/1 - 2秒的离心动作；LV组以6 - 10RM进行训练，采用10秒的向心/4秒的离心动作。显著性水平设定为0.05。LV组相对LP和KE的1RM增加，但增加百分比小于TS组，在SQ方面与C组无差异。对于肌肉耐力，LV组在LP方面的改善与TE组相似，在KE方面的改善小于TS组和TE组。所有组包括C组的身体成分均有改善（显著主效应）。总之，LV训练可提高肌肉力量，然而TS组的改善更大。LV训练可提高肌肉耐力，但未超过TE组或TS组的表现。对于所有其他变量，LV组除了与C组表现相当外，没有显著改善。
