What is the difference between concentric and eccentric?
Concentric reducers are a symmetrical, conical shaped device that enlarges or reduces a pipes diameter equally about the centerline. An Eccentric reducer is not Symmetrical about the centerline. For example, envision the flow through a gravity based pipe... picture it in terms of an elevation section view... the eccentric reducer maintains the flowline (a straight continuous line along the bottom) while the pipe size decreases from the top down.
Identify some posture and resistance constants?
Posture constants include alignment of the head over the shoulders, maintaining a neutral spine, and engaging the core muscles. Resistance constants involve creating tension in the muscles being worked, controlling the movement in both the concentric and eccentric phases, and using proper breathing techniques. Both posture and resistance constants are important to ensure effective and safe exercise performance.
Which resistance equipment may be referred to as double positive?
The resistance equipment referred to as "double positive" is typically a set of resistance bands that provide resistance in both directions of movement, both on the eccentric (lengthening) and concentric (shortening) phases of the exercise. This type of resistance helps engage more muscle fibers and increase overall muscle activation during workouts.
How do you know when your having contractions?
Contractions are characterized by a tightening or squeezing sensation in your abdomen that comes and goes in a regular pattern. You may also feel discomfort or pain in your lower back. Timing the contractions can help determine whether they are becoming more frequent and intense, indicating labor is progressing.
Which includes both speed and direction?
Velocity is a vector quantity that includes both speed and direction. Speed is the magnitude of velocity, while direction indicates its movement in a specific path or orientation in space.
Is a squat eccentric or concentric?
Both. Concentric: Exercise where the muscle is contracted under a load Eccentric: Exercise where the muscle is stretched under a load. So when you squat down its eccentric, when you come back up its concentric. Most exercises are both, with a few exceptions (i.e. jumping of a wall is mainly eccentric, while a punch is mainly concentric. Eccentric contraction is associated with increased muscle growth, but also DOMS (Delayed onset muscle soreness, when your muscles are very sore after a workout).
Is walking downhill a concentric or eccentric contraction of your quadriceps muscle?
Every step, whether going uphill, downhill, or on flat land, involves both an eccentric and concentric contraction.The eccentric contraction occurs when the quadriceps muscles lengthen as they load. In order for your quadriceps to lengthen, the knee must bend. Thus, the eccentric contraction in the walking motion occurs just after you step. This is perhaps more obvious with running than walking. After the foot touches the ground, the quadriceps is loaded eccentrically by the weight of the body as the knee bends.The concentric contraction of the quadriceps occurs then when the muscle shortens, as you push off from your foot. Again, this is probably more obvious with a running motion than walking motion. After the weight of your body has shifted onto the foot that is currently in contact with the ground (with your knee bent), your quadriceps contracts concentrically as the knee unbends and you lift your own body weight.So walking, even downhill, still involves both eccentric and concentric contractions. Walking (and running) downhill can lead to fatigue in your quadriceps due to the greater eccentric loading that occurs when going downhill. The range of muscle motion can be greater and your body is coming from "higher" up (its previous elevation on the hill), which can increase the load as well. As compared with concentric contractions, eccentric contractions can cause more damage to the muscle.

Whats difference between eccentric and concentric muscle contractions and examples of when in use?
Eccentric and Concentric contractions are both types of Isotonic Contraction. In isotontic contractions the length of a muscle changes, ie movement occurs, unlike an Isometric Contraction where force is applied but no movement occurs. Concentric contraction is the more obvious type of sixe change a muscle can have, it is when the muscle Shortens to move the Load. For example id one was to bend the elbow whilslt holding a weight (called a Bicep Curl) the Brachialis and, to a lesser extent, the Biceps Brach would shorten and pull the forearm up with the weight. Eccentric contracion is the type that muslce builder who wish to bulk up with inefficient muscle use. This is where the muscle Lengthens under conrtaction. To continue the same example above, imagine the weight was too heavy to hold up so it starts to fall under control. The brachialis and biceps muscles are still contracting trying to hold the weight in place but they are not producing enough force so the load is stretching them out.
What are the two types of exercise contractions?
# Resistance # Cardio Resistance is like weights, pushing against spring tension, pushups, situps... Cardio is the stuff that makes you sweat and makes your heart pound, like jogging, bicycling, jumping rope. Both are important.
How does concentric resistance training impact muscle strength and endurance?
Concentric resistance training can improve muscle strength and endurance by targeting the concentric phase of muscle contractions, which involves the shortening of muscles against resistance. This type of training helps to increase muscle force production and enhance the ability of muscles to sustain repeated contractions over time, leading to improvements in both strength and endurance.
What muscle contraction occurs when you do pull ups?
During pull-ups, the primary muscle contraction is an eccentric contraction of the latissimus dorsi and other upper body muscles as you lower yourself back down. Additionally, there is a concentric contraction when pulling yourself up, where these muscles shorten to lift your body. The biceps also engage in both phases, contributing to the movement. This combination of contractions helps build strength and endurance in the upper body.
What is the word for two circles having identical circumferences A circle is both concentric and?
Concentric and coincident, perhaps.
When are two coplanar circles concentric?
When the centers of both the circles are at the same point.
What are the similarities between concentric and gun platform castles?
They are both made of stone!!
If two circles have the same point then what are they called?
If you mean they both have the same centre - they're called 'concentric' circles.
