Muscle Physiology & Resistance Training

    This chapter provides an overview of the physiological principles related to assessing muscular strength and the methods for developing and
    sustaining muscular strength through exercise. It specifically focuses on the evaluation and training of the isolated lumbar extensor muscles,
    synthesizing research findings. Normative data for both genders and the interpretation of strength curves are included. Important considerations for evaluating and conditioning the lumbar extensor muscles, such as static and dynamic testing techniques, muscle fatigue characteristics, counterweighting effects, total torque, net muscular torque, strength curves, and the trainability of these muscles, are discussed.

    Comparison of Female Geriatric Lumbar Extension Strength

      In the conducted research, lumbar strength was compared between healthy asymptomatic geriatric women and symptomatic geriatric females. The INJ group assessed the back strength of the two control groups using MedX lumbar extension machines. The findings revealed a notable increase in range of motion (ROM) and back strength following the use of these machines.
