“Electromyographic kinesiology,” in Research Methods in Biomechanics, 2nd Edn., eds D. G. E. Robertson, G. Caldwell, J. Hamill, G. Kamen, and S. Whittlesey (Champaign, IL: Human Kinetics), 179–202. It is very rare that we witness trainers in our gym using single-leg presses. doi: 10.1007/s40279-016-0653-3, Day, M. L., McGuigan, M. R., Brice, G., and Foster, C. (2004). The use of unique isolation movements like this can sometimes drive a workout over 90 minutes. Once analyzed and it was ascertained which indexes better significantly predicted SI, two successive regression analyses were performed in order to obtain two further conversion equations based on RPE scores to verify whether the coefficients of regression of SI and the coefficients of regression of RPE were similar and comparable. We are aware sEMG vs. force relationship is nonlinear in many cases in accordance with Alkner et al. Disord. 41, 3–13. J. Safe, compact and high weight capacity are but a few features of the Powertec Leg Press. He does high-incline Smith machine presses and says it's his favorite movement for shoulders.

C. (2003). Another factor to consider is that muscle sEMG activity differed strongly between different body weight unloading conditions (such as during our LP), as showed by previous studies (Dietz and Colombo, 1998; Van Hedel et al., 2006). Phys. Due to the interdependence of the predictors relative to the load during the exercises, variance inflation factors (VIFs) were used to assess the multicollinearity, and when the VIFs showed that two or more predictors were collinear, these predictors were analyzed separately.

In contrast, the equation obtained for RPE showed high regression coefficients. The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. The authors wish to thank all the athletes who volunteered within this study and Ms. Dinah Olswang for English editing. Med. Now we're going to turn the Smith machine into a lying leg press machine. Winter, D. A. B., and Samozino, P. (2016). Alibaba.com offers durable, and eco-friendly leg press machine equipment for all types of gym facilities. Haff, G. G. (2000). Details of these analyses are reported in Table 2—Panel B. I'll bet that regular flat and incline benches are painful for them, but they can likely do Smith machine presses. 35, 2043–2047. Mov. Movements like the leg press (with two legs) allow bodybuilders to put 51% or more of the workload onto one of the legs, giving the other leg less of a workout. 32, 459–463. Because most of your body moves to perform squats, they tend to engage other muscle groups, such as your abs and hips, whereas leg presses just involve movement of the legs. J. (2015). The fact that many pro bodybuilders use this movement, while amateurs often do not, may be a direct result of the fact that professionals often have more time to train in the gym. If you are interested in purchasing home leg workout machines, it is important to understand the different options available to you. While it does not work like the hack squat and angled press machine, there are some advantages in choosing the machine in strengthening and defining your muscles in the lower part of your body. For elite athletes, every minute detail matters. 47, 1255–1269. Bench press exercise: the key points. In particular, the Smith machine leg press will emphasize your quadriceps, but also indirectly targets the glutes, hamstrings, and calves. A new approach to monitoring exercise training. doi: 10.2478/hukin-2013-0019. (2015). doi: 10.1016/j.gaitpost.2005.06.015. An electromyographic comparison of 4 closed chain exercises.

For MP, whole BW was considered as overweight for EL computation. (2013b). They are two different exercises working the leg muscles differently. doi: 10.1590/S1517-86922003000500007, Schwanbeck, S., Chilibeck, P. D., and Binsted, G. (2009). In other words (and limited to RPE), VL and VM may not be fully representative of the effort sustained during the two investigated exercises. doi: 10.1519/R-12782.1, Lagally, K. M., Robertson, R. J., Gallagher, K. I., Goss, F. L., Jakicic, J. M., Lephart, S. M., et al. Further limitation of the study is that—coherently with our interest in only the positive phase of the exercise—we focused on two knee extensors activity, whereas choosing an antagonist or other joints' muscles would have provided information more valuable within a motor control perspective. doi: 10.1109/TAC.1984.1103644. Lagally, K. M., McCaw, S. T., Young, G. T., Medema, H. C., and Thomas, D. Q. For these two analyses SI was used as the dependent variable, where the RPEs reported during MP and LP were considered as independent variables, and were, respectively named RPEMP and RPELP. doi: 10.1123/ijspp.2015-0638, Nuzzo, J.

It’s interesting so few amateurs use this movement because it’s actually a fairly common movement among advanced and professional athletes. Vertical Leg Press Machine (Smith Machine Leg Press) Known as the most challenging type of leg machine, a vertical machine for leg press requires you to lie on your back and use your legs to lift the weight upward. Therefore, we believe that can be matter for further studies in order to provide the reader with that practical indication as well. B. The seated leg press is a great way to exercise all four muscle groups of the quads – rectus femoris, vastus medialis, vastus lateralis and vastus intermedius. J. Electromyogr. A., Tesch, P. A., and Berg, H. E. (2000). To indicate the load during the LP, the following indexes were computed: NLLP (absolute nominal, that is 9 kg seat + stacks' weight); NLLP/BW (relative nominal load, that is 9 kg seat + stacks' weight, divided by BW); ELLP (absolute effective load, that is 9 kg seat + stacks' weight + BWsine10), and ELLP/BW (relative effective load, that is 9 kg seat + stacks' weight + BWsine10, divided by BW). Physiol. Quadriceps EMG/force relationship in knee extension and leg press. (2004). IEEE Trans. (2001). doi: 10.1002/mds.870130210, Escamilla, R. F., Fleisig, G. S., Zheng, N., Barrentine, S.

Table 1 provides a full-comprehensive description of the two exercises in terms of used discs/stacks masses, NLs and ELs, achieved SIs and RPEs, and efforts' durations. Pearson's correlation analysis showed that linear correlation was a valid model to describe the relation between the load of the exercises and the relative integrals of VM and VL (r > 0.8 for all the participants and load indexes; Hopkins et al., 2009). It can serve as a substitute for the leg press or be programmed similarly to the leg press. Among the newest leg press options available in fitness gyms is the vertical leg press unit, which requires you to push a weighted platform straight up while lying on your back. It's the best exercise." Initially, the integrals of the sEMGRMS VL and VM signals were summed to obtain a single variable, named SI, that was used to estimate the activity of both these muscles during the two exercises (i.e., MP and LP). Sci. These leg press machine sets are unisex, cheap, and certified items. Comparison of muscle force production using the Smith machine and free weights for bench press and squat exercises. doi: 10.1249/00005768-198205000-00012, Cotterman, M. L., Darby, L. A., and Skelly, W. A. J. 10, 361–374. For example, the contribution of a large hip extensor muscle is not considered in the same SI-based equation, whereas it accounts for the corresponding RPE-based one. Strength Cond. Required fields are marked *. What do the pros know that the amateurs do not? Vertical Leg Press Vs. Leg Press. Take into account that your stance should be like a squat, shoulder to hip width, toes pointed out to whatever degree feels comfy, and really forcing those knees out through the entire set. doi: 10.1249/01.MSS.0000099107.03704.AE, Van Hedel, H.
