The biceps and triceps work against each other to bend and straighten the elbow joint. If the bicep stop contracting and the triceps contract we will not be able to move our hand and can be paralyzed.
What else can I help you with?
What are agonistic pairs?
Pairs of muscles which work in a relationship, where both can support and oppose each other. The best and easiest example is the bicep and tricep. When the bicep is contracted the tricep is usually relaxed and visa versa. Think of it like a bicep curl. When you lift the dumbbell your bicep is contracting in the concentric contraction, but is still contracting on the way down, just on an eccentric contraction (i.e. acting as a brake). The whole time your tricep is relaxed. However when a tricep curl is performed the same principles apply but obviously using your tricep.
Do muscles always work in pairs?
Yes they do, they're called antagonistic pairs. However, I have also heard that there is a paradox that happens when you try to stand up from a sitting position which should be impossible because your hamstings and quadriceps are both contracting at the same time rather than one contracting and the other relaxing as antagonistic pairs should work.
What major muscles antagonists in a bench press?
Any time you are doing an exercise where you are pushing a secondary mover will be be the tricep. An antagonist when doing a pushing exercise will always be the bicep.
How can I effectively incorporate barbell bicep drag curls into my workout routine for maximum bicep muscle growth?
To effectively incorporate barbell bicep drag curls into your workout routine for maximum bicep muscle growth, perform the exercise with proper form and technique, gradually increase the weight over time to challenge your muscles, and ensure you are incorporating a variety of bicep exercises to target different muscle fibers.
What are the safety concerns when doing the dumbbell bicep curl?
You can save time and take steroids.
Why can't I extend my arms after a bicep workout?
After a bicep workout, you may have difficulty extending your arms due to muscle fatigue and soreness. This is a normal response to the stress placed on the bicep muscles during the workout. The muscles need time to recover and repair, which can temporarily limit your range of motion.
What are some effective short bicep exercises that can be done quickly and efficiently?
Some effective short bicep exercises that can be done quickly and efficiently include bicep curls, hammer curls, and concentration curls. These exercises target the biceps and can be completed in a short amount of time for a quick and effective workout.
How can I effectively strengthen and tone my arm muscles?
To effectively strengthen and tone your arm muscles, you can incorporate exercises such as bicep curls, tricep dips, push-ups, and shoulder presses into your workout routine. It is important to gradually increase the weight and intensity of your exercises over time to continue challenging your muscles. Additionally, maintaining a balanced diet and getting enough rest are also important factors in muscle growth and toning.
Why does our muscles became bigger when we are lifting heavy objects?
As you lift weights, your muscle's fibers are being ripped apart. After that, the muscle grows in order to be "normal" again and not ripped apart, making it bigger.
What happens to the muscle as the arm moves down?
One group of muscles contracts, and the other group extends. As an arm moves down, the bicep muscle (the one that faces the front side of the body and goes from the shoulder to the elbow) relaxes. When the muscle relaxes, it goes from being contracted to elongated. This relaxation happens at the same time that the tricep muscle (the one that faces the backside of the body and goes from the shoulder to the elbow) contracts. This happens because the human body's skeletal muscles have what can be considered compliments. I say this to mean that when a muscle relaxes, there is a muscle that contracts simultaneously. Therefore, they move antagonistically to each other. This is to serve the purpose of creating specific movements that help assist in locomotion. On the molecular level of what happens when a muscle contracts and relaxes, the actin and myosin filaments in muscle fiber overlap to contract and separate to relax.
Are there such things as partially contracted muscle fibers?
That is very good question! You do not have any thing like partially contracted muscle fibres, most probably. What you have got is partially contracted muscles. The muscle is more or less contracted as per the number of muscle fibres that are contracted at any given time.
Can smooth muscles stay contracted for long periods of time?
Yes
