What joint action is brought about by the concentric contraction of the rectus abdominis?
The concentric contraction of the rectus abdominis primarily facilitates trunk flexion, allowing the torso to bend forward. This action is crucial in movements such as sitting up from a lying position or performing crunches. Additionally, it aids in stabilizing the pelvis and spine during various activities, contributing to core stability.

Is a cricket bowl a concentric contraction?
No, a cricket bowl is not a concentric contraction. A concentric contraction occurs when a muscle shortens while generating force, such as when lifting a weight. In cricket, a bowl refers to the action of the bowler delivering the ball to the batsman. This motion involves a combination of eccentric and concentric muscle contractions.
Examples of different types of muscular contraction relating to four types of physical activity?
=1. Throwing a ball in a football match - this would be a concentric contraction because when bringing the ball behind the head your biceps do the concentric contraction. This is because the two ends of the bicep come closer to each other when doing the action. == ==2. pomallhorses in gymnastic - this is a isometric contraction because the biceps and triceps when doing this the ends of the muscle do not come closer of get further away form each other they stay the same. == ==3. Kicking a ball in rugby - this is an concentric contraction because the ends of the hamstring get further away when doing this action therefore it is a concentric contractions.== ==4. Sit ups - when doing sit ups your abdominals get closer when you sit up form the floor there for this is a concentric contraction.=
What joint action takes place when the spine contracts concentrically?
When the spine contracts concentrically, primarily during movements like flexion or extension, the muscles along the spine, such as the erector spinae, rectus abdominis, and obliques, shorten to produce movement. This action helps stabilize the vertebral column while allowing for controlled motion, such as bending forward or arching backward. Concentric contraction aids in maintaining posture and facilitating dynamic movements essential for various physical activities.
What Concentric contraction of the external oblique muscles on one side of the body contributes to?
Concentric contraction of the external oblique muscles on one side of the body contributes to trunk rotation and lateral flexion. This action helps in activities such as twisting the torso during sports or daily movements and stabilizes the spine during dynamic activities. Additionally, it plays a role in maintaining posture and providing support for the abdominal wall.
Is shoulder extension concentric or eccentric?
Shoulder extension can involve both concentric and eccentric muscle actions depending on the context. During a concentric action, the shoulder extensors, like the latissimus dorsi and teres major, actively shorten to move the arm backward. In contrast, during an eccentric action, these muscles lengthen under tension while controlling the descent of the arm. Thus, whether shoulder extension is concentric or eccentric depends on the specific movement being performed.

What is the joint action during the concentric phase of a sit-up?
During the concentric phase of a sit-up, the primary joint action involves flexion at the hip and lumbar spine. The rectus abdominis muscle contracts to lift the torso towards the thighs, while the hip flexors assist in bringing the pelvis closer to the ribcage. This coordinated movement effectively engages the core muscles, facilitating the upward motion of the body.
What are different types of contraction in sport?
The different types of contraction in sport is; Concentric Eccentric you also have to include; joint action e.g. Extension / flexion the agonist / agonistic muscle pairs e.g. hamstrings, quadriceps, biceps, triceps ect. & the joint itself e.g. knee, elbow, shoulder,
What Concentric contraction of the external oblique muscles on one side of the body contributes to?
Concentric contraction of the external oblique muscles on one side of the body contributes to trunk rotation and lateral flexion. This action helps in activities such as twisting the torso during sports or daily movements and stabilizes the spine during dynamic activities. Additionally, it plays a role in maintaining posture and providing support for the abdominal wall.
What type of muscle contraction occurs when the bicep performs flexion?
When the bicep performs flexion, a concentric contraction occurs. In this type of contraction, the muscle fibers shorten as they generate force, allowing the elbow to flex and bring the forearm closer to the upper arm. This action is primarily facilitated by the biceps brachii muscle, which contracts to lift the weight against gravity.
What is the concentric joint action in a lateral raise?
hamstring
What is the concentric joint action for lateral raise?
horizontal abduction
What is the concentric joint action of the hamstring curl?
flexion exstention
Concentric contraction of the hamstrings causes which joint action?
knee flexion and hip extension.Biceps femoris also: knee external rotation and hip external rotation.Semi tendinosus and Semi membranosus also: knee internal rotation and hip internal rotation.hamstrings eccentric contraction causes knee extension and hip flexion, whilst the antagonist muscles are passive.
