What else can I help you with?
Muscular contraction is defined as a contraction which moves against a constant resistance?
isometric contraction
The ability to exert maximum force against resistance?
Muscular strength
Ability of a muscle to exert force against resistance is called what?
Strength.
What is isotonic range?
Isotonic range refers to a type of muscle contraction in which the muscle shortens during contraction against a constant load. This contraction allows the muscle to produce movement through a full range of motion. It is commonly used in resistance training to build strength and muscle endurance.
Which type of strength training uses machines to increase muscle strength and endurance?
Types of Strength Training Exercises Static (isometric) exercise = muscle contraction without a change in the length of the muscle Dynamic (isotonic) exercise = muscle contraction with a change in the length of the muscle Concentric contraction = muscle applies force as it shortens Eccentric contraction = muscle applies force as it lengthens Types of Dynamic Exercise Constant resistance = constant load throughout a joint's range of motion Variable resistance = changing load to provide maximal resistance throughout a joint's range of motion Eccentric loading = placing load on a muscle as it lengthens Plyometrics = sudden eccentric loading and stretching followed by a concentric contraction Speed loading = moving a load as rapidly as possible Isokinetic exercise = exerting force at a constant speed against an equal force
What is isotonic and iso inertial contraction?
Isoinertial exercises are those that maintain a constant inertia = mass. A weight is placed on an extremity (arm or leg) and the extremity is put through a range or motion (or pattern of movement of that extremity). This range of motion can change direction but the force on the extremity doesn't change. An example of this is the yo-yo, it changes direction at the bottom, but the mass of the yo-yo stays the same. Isoinertial exercises strengthen both the muscle being targeted as well as the synergistic (helper) muscles as well. This type of exercise also helps to strengthen ligaments and tendons throughout the range of motion. Isoinertial exercises are not to be confused with (although hard not to) isotonic exercises. Isotonic exercises have a constant muscle force which often involves a constant resistance such as a free weight (dumbbell etc.).
Is there friction on a car at a constant speed?
Yes, there is still friction acting on a car at a constant speed. The tires experience rolling resistance against the road, and air resistance affects the car's motion. These frictional forces contribute to the total resistance the car needs to overcome to maintain a constant speed.
Application of muscular force without movement is called?
isometric- Application of muscular force without movement
What is a concentric contraction?
concentric contraction is atype of muscle contraction which the muscle shortens while genrating aforce The muscle shortens to produce movement. A muscle contraction in which shortening occurs.
What forms of energy are used when someone lifts a barbell to momentary muscular failure?
I don't know what you mean by momentary muscular failure. Surely if this happens he won't succeed in lifting the barbell? Lifting a barbell or indeed any muscular work done involves chemical changes in the muscles which provide the energy required, in this case raising the weight against the force of gravity. The energy used to lift a weight m kg a height of h meters is 9.81 x m x h joules.
What is isokenetic?
pertaining to a concentric or eccentric contraction that occurs at a set speed against a force of maximal resistance produced at all points in the range of motion.
What does muscular strength means?
The definition of muscular strength is the maximum amount of force that a muscle can exert against a form of resistance at one time. It is using muscles to exert force and refers to the amount of force those muscles produce.
