Effects of Full Verses Parallel Squats on Quadriceps Muscular Hypertrophy in Healthy Male Athletes

The Limitations of Anterior Knee Displacement during Different Barbell Squat Techniques: A Comprehensive Review

“…Due to the widespread use of the barbell squat in fitness, rehabilitation, and therapy, various techniques and modifications have been established by altering the squat bar position: high-bar back squat (barbell placed across the back slightly above the acromion), low-bar back squat (barbell placed across the back slightly below the acromion), front squat (barbell held in front of the chest approximately on the clavicles and above anterior deltoid), and overhead squat (barbell in an overhead position while elbows are fully extended and radial-ulnar joints pronated) [76][77][78][79]; modifying the squat depth: partial squat (representing a squatting depth less than parallel), which semantically includes quarter squats (QSs) (110-140 • knee angle) and half squats (HSs, 80 • to 100 • ), parallel squats (PSs) where the thighs are parallel to the floor (60-70 • ), and DSs or full squats (FSs), distinguished by a squat with thighs deeper than parallel, where knee angles have been shown to reach as much as 40-45 • knee flexion [7,19,34,38,[80][81][82]; modifying the stance width and foot rotation: narrow stance (107 ± 10% of the shoulder width), medium stance (142 ± 12% of the shoulder width), or wide stance (169 ± 12% of the shoulder width) with internally or externally rotated foot position [11,83]; or modifying the squatting surface: stable or instable underground (e.g., power board, BOSU ball, and balance cone) [79].…”

Quantitative MRI of Vastus Medialis, Vastus Lateralis and Gluteus Medius Muscle Workload after Squat Exercise: Comparison Between Squatting with Hip Adduction and Hip Abduction

“…There is increased interest because this exercise is considered a functional multijoint exercise that simulates more closely daily activities (Boudreau et al, 2009; Besier et al, 2009). There are several types of squat exercises classified in 3 groups: full or deep squat, half or parallel squat and partial or semi squat (Colker et al, 2002; Scaglioni-Solano et al, 2005). The partial squat can be prescribed at the beginning level when the stabilization of the joint and neuromuscular control is the primary goal (Chandler et al, 1989; Stensdotter et al, 2003; Tang et al, 2001).…”
