In this study, the total peak of joints’ torque, work, and the maximum jump height were measured in ten physically active male subjects performing the squat jump (SJ), and squat jump with arm swing (SJA). Accordingly, arm swing caused an increment in the heights of squat jump (p<0.001).The results revealed relationships between body mass and height with the total peak of joints’ torque (0.58<r<...

The influence of eccentric discharge of stored solids in squat silos has been highly valued by many researchers. However, calculation method of lateral pressure under eccentric flowing still needs to be deeply studied. In particular, the lateral pressure distribution on vertical wall could not be accurately recognized mainly because of its asymmetry. In order to build mechanical model of latera...

OBJECTIVE To assess the biomechanical evidence in support of advocating the squat lifting technique as an administrative control to prevent low back pain. BACKGROUND Instruction with respect to lifting technique is commonly employed to prevent low back pain. The squat technique is the most widely advised lifting technique. Intervention studies failed to show health effects of this approach an...

Pollution (i.e., sharing corrupted files, or contaminating index information with bogus index records) is a de facto problem in many file sharing Peer-to-Peer (P2P) systems. Since pollution squanders network resources and frustrates users with unprofitable downloads (due to polluted files) and unproductive download requests (due to bogus index records), the future success of file sharing based ...

[Purpose] The purpose of this study was to investigate the activation of back and lower limb muscles in subjects who were performing a squat exercise at different angles of trunk flexion. [Subjects and Methods] Twenty healthy subjects (age 21.1± 1.8 years, height 168.7 ± 8.2 cm, weight 66.1 ± 12.3 kg) volunteered. The activation of the erector spinae muscle, rectus femoris muscle, gluteus maxim...

1. Depth: Angle formed between the ankle knee and hip while squatting 2. Stance: distance between feet and center of mass over your ankles 3. Back-Hip Angle: Angle formed between the knees hips and back throughout the squat 4. Knee-Toe Alignment: Location and movement of knees throughout the squat • Certain components, such as required depth, stance and the angle at the hip, are fairly well-def...

The purpose of this study was to examine the relationships between muscle cross-sectional area (CSA), maximal strength, power output, and maximum potentiation characteristics. The vastus lateralis and biceps femoris CSA, one repetition maximum (1RM) back squat, 1RM concentric-only half-squat (COHS) strength, static jump power output, and maximum potentiation characteristics of 17 resistance-tra...

PURPOSE To compare EMG activity of selected hip and knee muscle groups in female athletes performing a modified single-leg squat and the 2-leg squat using the same relative intensity. METHODS Eleven Division I female athletes from a variety of sports (soccer, softball, and track) completed the study. EMG measurements were taken as the subjects completed 3 parallel repetitions at 85% of their ...

The aim of the present study was to investigate the effects of a multiple set squat exercise training intervention with superimposed electromyostimulation (EMS) on strength and power, sprint and jump performance. Twenty athletes from different disciplines participated and were divided into two groups: strength training (S) or strength training with superimposed EMS (S+E). Both groups completed ...
