Effects of Squat Variations on Quadriceps Muscle Thickness and Strength
The study was conducted using a randomized controlled trial design. Participants who met the inclusion criteria were randomly assigned to either the "Classic Squat Group" or the "Heel-Elevated Squat Group." Both groups completed an 8-week strength training program consisting of three sessions per week, following the resistance exercise principles recommended by the American College of Sports Medicine. The main component of the program was the assigned squat variation.
Baseline and post-intervention assessments at 8 weeks were performed according to standardized protocols. Exercise sessions were supervised by an experienced physiotherapist to ensure proper technique and minimize injury risk. Training intensity was progressively increased based on participants' adaptation and one-repetition maximum (1-RM) strength levels.

Grupo de Participantes / Braço |
Intervenção / Tratamento |
|---|---|
|
Experimental: Tradional Squat Group
Participants performed the tradional squat exercise as part of an 8-week training program.
|
Participants completed an 8-week supervised bodyweight squat program performed twice weekly, with progressive increases in training volume and intensity.
Squats were performed to approximately parallel depth, using a controlled ~2-s eccentric phase followed by maximal intended concentric velocity, with 2-min rest intervals between sets.

Experimental: Heel-Elevated Squat Exercise
Participants performed heel-elevated squat exercise as part of an 8-week training program.
|
Participants in the Heel-Elevated Squat Group performed all repetitions with both heels supported on rigid 5-cm wedges.
Participants completed an 8-week supervised bodyweight squat program performed twice weekly, with progressive increases in training volume and intensity.
Squats were performed to approximately parallel depth, using a controlled ~2-s eccentric phase followed by maximal intended concentric velocity, with 2-min rest intervals between sets.

Muscle Strength (Isomed 2000 Isokinetic Dynamometer)
Prazo: Baseline and 8 weeks post-intervention
|
Quadriceps muscle strength was assessed using a Isomed 2000 isokinetic dynamometer, which is considered a gold-standard method for evaluating muscle performance.
Isokinetic testing measures maximal torque produced by the muscle throughout the range of motion at a constant angular velocity, providing reliable data on muscle function.
Knee extension strength were evaluated.

Assessment of Muscle Thickness
Prazo: Baseline and 8 weeks post-intervention
|
Before measurement, participants rested for 20 minutes, and quadriceps muscle thickness was assessed at the midpoint between the anterior superior iliac spine and the superior pole of the patella using B-mode ultrasonography.
Anterior thigh muscle thickness was defined as the distance between the superficial fascia of the rectus femoris and the femoral periosteum, representing the combined thickness of the rectus femoris and vastus intermedius.
