There are 3 types of muscle fiber contraction during exercise. 1) CONCENTRIC or “positive” contraction - shortening of the muscle fibers during contraction. The joint angle decreases between the proximal and distal attachments. 2) ISOMETRIC or “neutral” contraction - No change in the length of the muscle fibers during contraction. The joint angle does not change. 3) ECCENTRIC or “negative” contraction - lengthening of the muscle fibers during contraction. The joint angle increases between the pr

♦️BRAXTON HICKS VS. LABOR CONTRACTIONS ♦️Both are a contraction or tightening of the uterus which is a muscle.♦️Braxton Hicks contractions are toning of the uterus or thirsty muscle. They last under 30 seconds, may or may not have discomfort and can be all over the belly or localized to an area of the belly. No pattern to them and usually happens randomly. Dehydration is the most common reason for these contractions but not limited to this reason.♦️Labor contractions are the body warming up and
