![]() To note that results are specific to isometric training at a fixed joint angle.Īlthough such protocols are insightful for generating mechanistic hypotheses, theirĭesigns are of questionable relevance to ecologically valid RT programs, thereby Partial excursion is carried out at a long muscle length. Training with a partial ROM may be equally effective as a full ROM provided that the Training with joint angles > 70° compared with just 0.47% per week withĪngles ⩽ 70° (effect size difference = 0.35). 10 The authors reported average increases in muscle size of 1.16% per week when Heavy loads in a muscles strongest range, which conceivably leads to greaterĪ recent systematic review concluded that isometric training at longer muscle lengthsĮlicited greater increases in muscle size compared with isometric training at 8 Alternatively, others claim that partial ROM training affords the use of Shortening and lengthening of muscle fibers. Their complete ROM elicits greater stimulation of fibers by maximizing the On one hand, some theorize that taking repetitions through Opinions as to whether training with a partial or complete ROM is optimal for While the evidence for training-induced variations in ROM on muscular strengthĪppears compelling, its effects on hypertrophy are less clear. ![]() That ultimately translates into greater adaptations within the functional training range. Whereby neural adaptations occur with persistent training specific to a given ROM Collectively, findings are consistent with the principle of specificity, Quarter squats, half squats or full squats were greatest at the ROM used in Similar results were foundīy Rhea et al., 7 who observed that increases in 1RM squat pursuant to performing 16 weeks of In greater 1RM improvements in the half squat exercise. Squat 1 repetition maximum (1RM) strength while training using half squats resulted 6 study, training with quarter squats resulted in higher increases in quarter 6 showed that these findings translated to dynamic exercise as well. Increases most apparent within several degrees adjacent to the angle of Initial work on the topic wasĬarried out using isometric exercise, with results consistently showing strength Training must involve complete excursion of the joint. To the joint angle trained thus, to achieve strength throughout a full ROM, 2 Indeed, a majority of research shows that strength adaptations are specific Some authors have proposed that training through a full ROM is necessary to maximize Play an important role in muscular adaptations. ![]() 1 Despite its relative lack of attention in the literature, ROM potentially can RT prescription briefly discusses ROM but stops short of making practical recommendations. 2 For example, the 2009 American College of Sports Medicine position stand on Occurs at a given joint during exercise performance. Is the range of motion (ROM), operationally defined as the degree of movement that One variable that has received relatively little attention 1 Variables most often discussed in this regard include volume, load, andįrequency, among others. It is well-established that the manipulation of resistance training (RT) variables isĪn important factor in optimizing RT-induced muscular adaptations. The response to variations in ROM may be muscle-specific however, this No study to date has investigated how ROM influences Limbs is limited and conflicting, precluding the ability to draw strong Alternatively, research on the effects of ROM for the upper Of literature, it can be inferred that performing RT through a full ROM confersīeneficial effects on hypertrophy of the lower body musculature versus training “excellent” based on the modified PEDro scale. The methodological quality of all included studies was deemed to be Sample of the studies was n = 135, which comprised 127 men andĨ women. Limbs while the other two focused on the upper extremities. Six studies were identifiedĪs meeting inclusion criteria: four of these studies involved RT for the lower Based on the available literature, we aimed to drawĮvidence-based recommendations for RT prescription. The purpose of this study was to systematically review the literature as to theĮffects of performing exercise with a full versus partial range of motion (ROM)ĭuring dynamic, longitudinal resistance training (RT) programs on changes in
