The Effect of Different Types of Squat Exercises on Muscle Strength and Muscle Oxygenation

13. juli 2026 opdateret af: FİLİZ EYÜBOĞLU, Uskudar University

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.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: Classic Squat Group
Participants performed the classic squat exercise as part of an 8-week resistance training program.
Andet: Classic Squat Group
Participants in the Classic Squat Group performed a progressive resistance training program three days per week for a total of eight weeks. The squat exercise was performed with full foot contact maintained on a stable ground surface. Training intensity was prescribed at 70-85% of each participant's one-repetition maximum (1-RM) and was progressively adjusted according to individual adaptation. All training sessions were supervised by a physiotherapist to ensure correct technique and safety.
Eksperimentel: Heel-Elevated Squat Exercise
Participants performed heel-elevated squat exercise as part of an 8-week resistance training program.
Andet: Heel-Elevated Squat Group
Participants in the Heel-Elevated Squat Group also completed a progressive resistance training program three days per week for eight weeks. The squat exercise was performed using a 20-degree inclined platform placed under the heels. Training intensity was set at 70-85% of each participant's one-repetition maximum (1-RM) and was progressively increased based on individual performance and adaptation. All sessions were conducted under the supervision of a physiotherapist to maintain proper form and reduce injury risk.

Foranstaltningsbeskrivelse
Tidsramme
Muscle Oxygenation (Moxy Monitor - NIRS)
Tidsramme: Baseline and 8 weeks post-intervention
Muscle oxygenation was assessed using a near-infrared spectroscopy (NIRS)-based Moxy Monitor. The device was placed on the vastus lateralis muscle of the quadriceps during exercise to continuously and non-invasively record the balance between local oxygen delivery and utilization.

Foranstaltningsbeskrivelse
Tidsramme
Muscle Strength (Isomed 2000 Isokinetic Dynamometer)
Tidsramme: 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.
