1 2 Objective: 1. Evaluate single leg squat performance 1-2 years after arthroscopy for intra3 articular hip pathology, compared to controls and the non-operative limb. 2. Investigate 4 whether single leg squat performance on the operated limb was associated with hip muscle 5 strength. 6 Design: Cross-sectional study 7 Setting: Private physiotherapy clinic and university laboratory. 8 Participa...

The squat is one of the most frequently used exercises in the field of strength and conditioning. Considering the complexity of the exercise and the many variables related to performance, understanding squat biomechanics is of great importance for both achieving optimal muscular development as well as reducing the prospect of a training-related injury. Therefore, the purpose of this article is ...

The back squat and barbell hip thrust are both popular exercises used to target the lower body musculature; however, these exercises have yet to be compared. Therefore, the purpose of this study was to compare the surface electromyographic (EMG) activity of the upper and lower gluteus maximus, biceps femoris, and vastus lateralis between the back squat and barbell hip thrust. Thirteen trained w...

Recent studies indicate that the utilization of the hexagonal barbell jump squat (HBJS) compared with the traditional barbell jump squat may offer a superior method of developing peak power. The notion that a single optimal load may be prescribed in training programs aiming to develop peak power is subject to debate. The purpose of this study was to identify the optimal load corresponding with ...

In this paper, we propose a three-dimensional design and evaluation framework and process based on a probabilistic-based motion synthesis algorithm and biomechanical analysis system for the design of the Smith machine and squat training programs. Moreover, we implemented a prototype system to validate the proposed framework. The framework consists of an integrated human-machine-environment mode...

T he squat is widely used as a staple exercise in resistance training programs. It is used by athletic and recreational populations alike to enhance both strength and hypertrophy of the lower-body musculature and improve functional performance (17). However, considerable controversy exists as to optimal squat depth, particularly as to whether deep squatting increases the risk of injury to the k...

The purpose of this study was to investigate the relationship between movement velocity and relative load in three lower limbs exercises commonly used to develop strength: Leg Press, Full Squat, and Half Squat. The percentage of one Repetition Maximum (%1RM) has typically been used as the main parameter to control resistance training, however more recent research has proposed movement velocity ...

This article traces the contributions of Prof. E.O. Tuck to the field of mathematical ship squat prediction. The review expands on Tuck’s own review of his early work [1] and describes the use of his formulae in modern squat prediction methods. A method for calculating Tuck’s sinkage and trim coefficients using easilyobtainable ship parameters is also described.

CONTEXT Multiple factors have been suggested to increase the risk of faulty dynamic alignments that predict noncontact anterior cruciate ligament injury. Few researchers have examined this relationship using an integrated, multifactorial approach. OBJECTIVE To describe the relationship among static lower extremity alignment (LEA), hip muscle activation, and hip and knee motion during a single...
