AGONIST: The muscle most involved in producing a movement
ANAEROBICS: The word anaerobic means without oxygen. It is a highly intense, short term activity such as sprinting and weightlifting.
Agonist muscle- A muscle that is very effective in causing a certain joint movement. Also called the prime mover.On a biceps curl, the biceps is the agonist muscle that flexes the elbow joint.
Agonist: The contracting muscle as distinguished from the relaxing muscle.
Amino Acids: The building blocks of proteins and the end products of protein digestion. There are 20 essential amino acids for human metabolism and growth.
Agonist
A muscle responsible for producing a specific movement through concentric muscle action.
Amino Acids
A class of organic compounds that are building blocks from which protein is constructed.
Agonist Muscle directly engaged in contraction that is primarily responsible for movement of a body part.
All-or-None Muscle fibre contracts fully or it does not contract at all.
agonists These muscles cause the movement to occur. They create the normal range of movement in a joint by contracting.
Agonist - Also known as the prime mover, this refers to the muscle that causes motion.
Antagonist Stabilizer
A muscle that contracts to maintain the tension potential of a biarticulate muscle at the adjacent joint. The antagonist stabilizer may be contracted throughout or at only one extreme of the movement.
beta agonist a beta-agonist or beta adrenoceptor agonist is a drug or chemical that partially mimics the effects of epinephrine, primarily targeting the beta adrenoceptors which accelerate heart rate and increase blood pressure (beta-1), ...
Agonist
A muscle responsible for moving the body part that contracts or shortens.
AMDR
An abbreviation for the Adult Minimum Daily Requirement of certain nutrients as established by the United States Food and Drug Administration (FDA).
Agonist/antagonist relationship: (Not to be confused with the roles described above). For every muscle in the body, there is another muscle capable of resisting its force. If this were not the case, controlled human movement would not be possible.
Antagonist Workouts - Antagonist training refers to working opposing muscle groups in the same workout.
The antagonist muscle to the two major calf muscles is called the tibialis anterior. It's a small and relatively weak muscle compared to the major calf muscles (the gastrocnemius and the soleus) and not particularly useful for doing Supersets with.
Agonist [back to top] Muscles directly engaged in contraction as related to muscles that relax at the same time. Amenorrhea [back to top] Cessation of regular menstrual flow.
This drug is classified as a Beta-2 agonist, and is used for treating asthma. It is not an anabolic steroid, or a growth hormone.
Yohimbine is an alpha2 receptor antagonist. The catecholamine norepinephrine (NE) is released in times of stress and intense activity to increase the amount of available energy by releasing stores nutrients (i.e. fatty acids from fat cells).
Full range exercise movements are advantageous for strengthening the prime-mover, or agonist muscles--the muscles directly trained in the exercise, such as the biceps in the biceps curl.
SUPER SET: Represents a method in which the athlete performs a set for the agonistic muscle of a given joint, followed without a rest period by a set for the antagonistic muscles.
You can use this superset style of training for two different muscle groups, but only if they have an agonist/antagonist relationship with each other.
Static Active flexibility -- this refers to the ability to stretch an antagonist muscle using only the tension in the agonist muscle. An example is holding one leg out in front of you as high as possible.
This is because of the agonist-antagonist relationship which means the glutes and hip flexors are opposing muscles. When the primary hip extensors become weak the synergist (helper) muscle takes over causing further problems.
You need to work the agonist and antagonist muscle groups. Just like you would with your regular gym workouts. You would never just train your chest but neglect your back (well some people do, but that's another story).
The drug belongs to the class of asthma medications known as beta2-receptor agonists (commonly called beta agonists).
Position in which muscles in an agonist/ antagonist relationship, or bilateral muscles do not have equal tone, and thus are imbalanced
muscle strain ...
results: The results are often reported at different speeds so that a speed/strength/power relationship can be seen. Comparison of the relative strengths of the different sides of the body, or agonists versus antagonists (e.g.
The following table is reported values for joint agonist-antagonist ratios at slow isokinetic speeds.

ACTIVE STRETCH : Muscles are stretched using the contraction of the opposing muscle, (antagonist). For an example stretching the triceps, requires the biceps to contract.
AEROBIC CAPACITY : Another term for maximal oxygen uptake (VO2 Max).
When you stretch your muscles you are exercising agonist muscle groups. When one muscle group is contracting, opposite muscle groups are lengthening. Move your arms, legs, and feet within the comfort of your ability level.
The Brisbane trial is the best western study of the Buteyko Method. The trial results indicated asthmatics using the Buteyko Method reduced use of beta-agonists (relievers) by 96% and steroids by 49%.
Active StretchingActive stretching is also referred to as static active stretching. An active stretch is one where you assume a position and then hold that position with no assistance other than using the strength of your agonist muscles. A great exa.
Full-range of motion movements contract and strengthen the muscle you're working (the prime mover) and stretch the opposing (antagonist) muscle. This contributes to both muscle strength and joint flexibility.
