What does it mean for a muscle to be tight?
Muscle stiffness typically occurs after exercise, hard physical work, or lifting weights. You may also feel stiffness after periods of inactivity, like when you get out of bed in the morning or get out of a chair after sitting for a long time. Sprains and strains are the most common reasons for muscle stiffness.
What is the difference between overactive and underactive muscles?
Overactive and underactive muscles are usually reflections of muscle imbalances and posture. Overactive muscles are not necessarily strong or tight, but are hypertonic or have chronic increased tone. Whereas underactive muscles may not always be weak and lengthened, but are hypotonic or have chronic decreased tone.
What does muscle inhibition mean?
So what exactly is muscle inhibition then? Essentially, it’s a muscle that is receiving no or distorted neurological input. The easiest way to tell if you have muscle inhibition is when you move a muscle at the joint and it feels sluggish and lacks range of motion.
What is the mechanism of muscle spasm?
Muscle spasm can be defined as persistent, involuntary muscle contraction (not including spasticity, a phenomenon of central nervous origin). The main reason why pain arises in muscle spasm is muscle ischemia, which leads to a drop in pH and the release of pain-producing substances such as bradykinin, ATP, and H+.
Can muscles be weak and tight?
Muscle tightness is a feeling and not a mechanical condition. Muscles that feel tight are not always shortened and stiff but can in fact be elongated, fatigued / weak!
Can muscles be tight and weak?
Do you stretch overactive or underactive muscles?
When a muscle is overactive and tight, it is beneficial to stretch and allow that group of muscles to relax while at the same time working to activate and strengthen the underactive muscle group that is inhibited and weak which will help you find the balance we refer to in your posture.
Is a weak muscle a tight muscle?
Whenever a weak muscle is forced to work beyond its capacity, it will tighten and, therefore, be more subject to stress and strain. It is imperative to always build the strength and endurance of muscles along with flexibility.
Why do muscle spasms happen physiology?
Spasms of skeletal muscles are most common and are often due to overuse and muscle fatigue, dehydration, and electrolyte abnormalities. The spasm occurs abruptly, is painful, and is usually short-lived. It may be relieved by gently stretching the muscle.
Which process must occur for a muscle to be able to relax?
Relaxation: Relaxation occurs when stimulation of the nerve stops. Calcium is then pumped back into the sarcoplasmic reticulum breaking the link between actin and myosin. Actin and myosin return to their unbound state causing the muscle to relax.
