Abstract

Abstract The range of motion (ROM) may affect the external maximal load during back squat (BS) exercise. The correct ROM manipulation can be useful as an exercise load manipulation strategy, changing the volume load during a resistance training session. The aim of this study was to evaluate the acute effects of ROM on relative load, absolute load and the rating of perceived exertion (RPE) during partial and full BS exercise with adjusted loads. Fifteen male individuals (age: 26.5±4.5 years; height: 173±6 cm; body mass: 80.6 ± 8.8 kg; resistance training experience 5±3 years) participated in this study. The experimental procedure was conducted in two sessions. In the first session, brief familiarization and a 10-repetition maximal test (10-RM) was performed for partial (PBS) and full BS exercise (FBS) with 30-min of rest interval. During the second session, all subjects performed 1 set of 10-RM in both conditions (partial and full ROM), and relative load, absolute load, and RPE were evaluated. A paired t-test was used to compare means. The results showed higher values for PBS when compared to FE exercise: relative load (PBS: 1.14±0.24xBW vs. FBS: 0.87±0.24xBW; P<0.001), and absolute load (PBS: 925±249 kg x FBS: 708±232 kg, P<0.001). Similar RPE was observed between conditions (PBS: 8.6±1.3 IEP x FBS: 8.5±1.0 IEP, P=0.855). It was concluded that PBS allowed higher relative load and absolute load during 10RM, without effects on RPE.

后蹲运动的运动范围影响绝对容积负荷，而不改变感知用力的等级

运动范围(ROM)可能影响背部深蹲(BS)运动时的最大外负荷。正确的ROM操作可以作为一种运动负荷操作策略，在阻力训练期间改变容量负荷。本研究的目的是评估在调整负荷的部分和完全BS运动中，ROM对相对负荷、绝对负荷和感知劳累等级(RPE)的急性影响。男性15例(年龄26.5±4.5岁;高度:173±6cm;体重:80.6±8.8 kg;有抗阻训练经验(5±3年)者参加本研究。实验过程分两次进行。在第一阶段，对部分(PBS)和完全BS运动(FBS)进行了简短的熟悉和10次重复最大测试(10-RM)，休息时间为30分钟。在第二阶段，所有受试者在两种情况下(部分和完全ROM)进行1组10-RM，并评估相对负荷、绝对负荷和RPE。采用配对t检验比较均数。结果显示，与FE运动相比，PBS值更高:相对负荷(PBS: 1.14±0.24xBW vs. FBS: 0.87±0.24xBW;P<0.001)，绝对负荷(PBS: 925±249 kg × FBS: 708±232 kg, P<0.001)。两组RPE相似(PBS: 8.6±1.3 IEP × FBS: 8.5±1.0 IEP, P=0.855)。结果表明，PBS在10RM期间允许更高的相对载荷和绝对载荷，而对RPE没有影响。

期刊介绍： The Brazilian Journal of Kinanthropometry and Human Performance is a journal of Physical Education, Kinesiology, Sport and related areas, whose focus is human movement, being reviewed by an international panel of peers, with emphasis on the measurement of the man in its morphological and functional aspects, as well as conditioning factors of physical performance. Given the multidisciplinary nature of the journal, these areas of study are approached in several contexts, with interactions with social, behavioral, health and environmental aspects. The journal publishes original articles as well as relevant Review/Update articles and Points of View.
