This book was released on 2019 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: Muscle strength is an essential part of a healthy life. One frequently used exercise for lower body strength development is the squat. Common variations of the squat are front and back squats. Recently a new transformer bar has been developed that allows the bar to be placed on the squatters back while the load can be shifted back and forth. The purpose of the current study was to quantify the biomechanical differences in back and front squats' kinematics and kinetics using a conventional bar or a transformer bar. The results showed that the more front load placement resulted in higher low back torques. However, the regular bar back squat and the squats with a transformer bar demonstrated similar hip and knee torques. The regular bar front squat was the only condition that showed increased knee torques but decreased hip torques compared to the regular bar back squat and the squats with a transformer bar. In conclusion, a transformer bar is just as effective in training the hips and knees as a regular back squat and may be considered for people with upper extremity limitations. Additionally, the regular front squat has more knee loading and less hip loading compared to other squats and may be consider for people who want to focus on knee strength training. Furthermore, squats with more forward placements of the load could result in greater low back loading and should be taken into consideration for those with low back impairments.

Book Synopsis A Biomechanical Comparison of Isometric Back Squats and Belt Squats by : Jacob S. Layer
Download or read book A Biomechanical Comparison of Isometric Back Squats and Belt Squats written by Jacob S. Layer and published by . This book was released on 2017 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: Background: Squat variations are one of the most effective and widely used lower body exercises. Since most squat variations involve the upper body, spinal and upper extremity pathologies often preclude their use. The belt squat presents a possible alternative. Because resistance is applied to the pelvis, external loading of the upper body appears to be eliminated. Until now, no comparisons have been made between the biomechanics of the back squat and the belt squat. Purpose: to compare the force production, low back moment, and lower extremity joint moments during back and belt squats, performed isometrically. Methods: 26 participants performed isometric belt squats and isometric back squats at four depths. Ground reaction forces and motion were recorded using 3D motion capture and force plates. Joint moments were calculated using inverse dynamics. A regression approach was used to predict joint moments and vertical ground reaction forces at a 45o thigh segment angle. Results: The belt squat produced greater vertical ground reaction forces, knee moments, and ankle moments, while significantly reducing low back moments. Hip moments were not significantly different. Conclusion: The belt squat appears to be an effective means of training the lower body, while minimizing upper body involvement.
Book Synopsis Comparison in Joint Angles and Joint Forces Between the Safety-squat Bar and Traditional Barbell Back Squat by : David Johansson (Graduate student)

This book was released on 2021 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary objectives for this investigation were to compare the kinematic and kinetic differences between performing a parallel back squat using a Traditional Barbell (TB) or a Safety-Squat Bar (SSB) while using the same foot-stance for both barbells. Fifteen healthy males who were experienced at performing the barbell back squat (23.13 + 3.93 years of age) performed back squat with traditional barbell and a safety squat bar at 85% of their respective 1RM with each barbell. A 3x2 Factorial ANOVA with repeated measures was used to determine the kinetic and kinematic differences between the exercises. Results showed that the TB exercise experienced significantly greater maximum hip angle (P

Book Synopsis Lower Body Kinematic Comparisons Between Front and Back Squats in Response to Loads by : Joosung Kim
Download or read book Lower Body Kinematic Comparisons Between Front and Back Squats in Response to Loads written by Joosung Kim and published by . This book was released on 2014 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: The squat is considered as one of the most popular exercises prescribed by therapists, athletic trainers, researchers, coaches, and athletes for injury prevention and strength and conditioning. The purpose of this study is to examine the lower body kinematic comparisons between front and back squat exercises in response to loads. The result of the study shows that there is a statistically significant difference in the knee flexion, trunk inclination, and angular velocity of spine between both squat exercises. The results suggest the importance of prescribing strengthening exercises targeting the knee joint in the front squat and the trunk stability in the back squat.
Book Synopsis Comparison Between the Trap Bar Dead Lift and Back Squat Exercises on Vertical Jump by : Douglas A. Young (Jr.)
Download or read book Comparison Between the Trap Bar Dead Lift and Back Squat Exercises on Vertical Jump written by Douglas A. Young (Jr.) and published by . This book was released on 2011 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ability to produce power during competition is essential. Football requires explosive power in order to get off the ball faster, increase speed of the first step, and increase the height of the vertical jump. Most strength training professionals use the back squat to increase power of the lower extremities; however, as large forces are placed on the back, athletes are at greater risk for injury. The trap bar dead lift is similar to the back squat in movement and form, but the trap bar dead lift reduces the force on the lower back. After testing for maximum vertical jump, athletes at Timpview High School participated in a strength program using either back squats or trap bar dead lift for seven weeks. A pre-test, mid-test and post-test were performed to calculate the increase in maximum vertical jump, if any. It was found that neither lift was significantly different than the other when testing for maximum vertical jump. These results will allow strength training professionals to use the trap bar dead lift instead of the back squats in subjects similar to those participating in the study.

Book Synopsis Mean-Field Magnetohydrodynamics and Dynamo Theory by : F. Krause
Download or read book Mean-Field Magnetohydrodynamics and Dynamo Theory written by F. Krause and published by Elsevier. This book was released on 2016-01-22 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mean-Field Magnetohydrodynamics and Dynamo Theory provides a systematic introduction to mean-field magnetohydrodynamics and the dynamo theory, along with the results achieved. Topics covered include turbulence and large-scale structures; general properties of the turbulent electromotive force; homogeneity, isotropy, and mirror symmetry of turbulent fields; and turbulent electromotive force in the case of non-vanishing mean flow. The turbulent electromotive force in the case of rotational mean motion is also considered. This book is comprised of 17 chapters and opens with an overview of the general concept of mean-field magnetohydrodynamics, followed by a discussion on the back-reaction of the magnetic field on motion; the structure of the turbulent electromotive force; homogeneous and two-scale turbulence; turbulent electromotive force in the case of rotational mean motion; and the dynamo problem of magnetohydrodynamics. The dynamo theory, which is based on mean-field magnetohydrodynamics, is explained and its applications to cosmical objects are described. The remaining chapters explore toroidal and poloidal vector fields; a simple model of an a-effect dynamo; and spherical models of turbulent dynamos as suggested by cosmical bodies. This monograph will be of interest to physicists.
