Understanding Spinal Fatigue and Muscle Responses in Resistance Training

Exploring spinal fatigue as a physiological mechanism and its impact on motor neuron signaling, along with testing methods and muscle response variations in resistance training. Emphasizing the importance of tempo in resistance training, discussing rep ranges, motor unit recruitment, and age-related considerations, as well as risks associated with steroid use. Delving into the differences between mechanical tension in concentric and eccentric muscle movements, focusing on force production dynamics and effort perception during weightlifting.
