Does Pelvic Tilt Angle Influence the Isokinetic Strength of the Hip and Knee Flexors and Extensors?

The purpose of this study was to examine the effect of pelvic tilt angle on maximum hip and knee muscles' strength and antagonist/agonist strength ratios. Twenty-one young males and females performed maximum isokinetic concentric knee extension-flexion and hip extension-flexion efforts at 60°·s, 120°·s, and 180°·s from three positions: anterior, neutral, and posterior pelvic tilt. Peak torques and knee flexor-to-extensor and hip flexor-to-extensor torque ratios were analyzed.

Effect of Bridge Exercise Duration on Lateral Abdominal Muscle Thickness and Gluteus Maximus Activation.

Context: Bridge exercises are extensively used in trunk-strengthening programs. The aim of this study was to investigate the effect of bridging duration on lateral abdominal muscle thickness and gluteus maximus activation.

Design: Cross-sectional.

The Role of CO on Respiration and Metabolism During Hypercapnic and Normocapnic Recovery From Exercise.

High intensity exercise can lead to depletion of CO from the body (hypocapnia). This disturbance becomes more noticeable during recovery or between seasons of intermittent exercise, putting the subject in a neural fatigue state. : A possible hypothesis to address this condition would be to provide high CO mixtures (hypercapnic) during the recovery period from exercise in order to relieve hypocapnia.
