Co ncentric vs Eccentric — how do they affect your squats? Both terms relate to the contractions of the muscle we use in bodybuilding and weightlifting. Isotonic contraction occurs when your muscles change length and produce the force necessary to move the joints in your body. Related: Isotonic Vs. Isometric Contraction. Awareness of both the eccentric and concentric movements involved will help you recognize the multiple muscles that are strengthened.
Standing involves a series of relatively immobile positions separated by brief intervals of movement during which swaying occurs. When a subject is in the easy standing position, few muscles of the back and lower limbs are active during the immobile periods. The position of the line of gravity, which is determined by the distribution of body weight, is important in determining the degree of muscular activity involved in maintaining all phases of posture. The line of gravity extends superiorly through the junctions of the curves of the vertebral column and inferiorly in a line posterior to the hip joints but anterior to the knee and ankle joints fig. When a subject is in the easy standing position, the hip and knee joints are extended and are in their most stable positions.
Sitting down and standing up require a coordinated effort from muscles surrounding your hip, knee and ankle joints. Joints, or articulations, are junctions between two bones that permit a degree of movement. When you sit down, your hip joints flex, which means that the joints bend so that your thighs move forward, your knees flex and your ankles dorsiflex -- where the top of your feet move up toward your shins. When you stand up, your hip joints extend or straighten so that your thighs move backward while your knees extend and your ankles plantar flex, which means that your feet point and move away from your shins. Your ankle, knee and hip joints are all considered synovial, or freely movable articulations.
Brown, Nursing Department Sharon S. Kathy, a year-old woman, awakens one morning to a tingling, numb sensation covering both of her feet. This has happened to her a number of times throughout the year. Background: Scoliosis is defined as an abnormal lateral curvature of the spine, most often diagnosed in childhood or early adolescence. Scoliosis affects.
Standing , also referred to as orthostasis , is a human position in which the body is held in an upright " orthostatic " position and supported only by the feet. Although seemingly static, the body rocks slightly back and forth from the ankle in the sagittal plane.
