During concentric contraction, cellular activity includes the shortening of muscle fibers, which generates force to move a load or overcome resistance. This process is fueled by the consumption of ATP and involves the sliding of actin and myosin filaments within the muscle fibers.
What else can I help you with?
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 does cellular activity do during the phases of Eccentric contraction?
During the eccentric contraction phase, cellular activity involves lengthening the muscle fibers while generating force. This phase creates tension in the muscle as it elongates, allowing for controlled movement and resistance against external forces. Additionally, cellular processes such as protein breakdown and remodeling contribute to muscle adaptation and strength gains.
What is the function role of t tubules?
Enhance cellular communication passage for nervous stimulation during muscle contraction.
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 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.
What muscle contraction occurs in the biceps brachii during the upward phase of the bicep curl?
a concentric contraction- a concentric contraction involves the muscle length, shortening during a contraction! YA-trick-YA!

What is scientific word use when a muscle gets longer and get shorter?
The scientific terms for these processes are "eccentric contraction" and "concentric contraction." During eccentric contraction, a muscle lengthens while generating force, often when resisting an external load. Conversely, during concentric contraction, a muscle shortens while actively generating force, typically when lifting or moving a load. Together, these actions are essential for muscle function and movement.
What is commonly used to produce ATP during skeletal muscle contraction?
creatine phosphate, anaerobic cellular respiration, aerobic cellular respiration
What is the correct phase order of the stretch shortening cycle?
The correct phase order of the stretch-shortening cycle is eccentric contraction, amortization phase, and concentric contraction. This sequence allows for energy storage during the eccentric phase, a brief pause to transition from lengthening to shortening, and then rapid muscle shortening in the concentric phase for powerful movement.

What must be present during cellular respiration?
Oxygen and fuel and activity.
What is the energy source of most cellular activity?
Adenosine triphosphate (ATP) is the main energy source for most cellular activities. It is produced during cellular respiration through the breakdown of glucose and other nutrients in the presence of oxygen. ATP stores and releases energy for various cellular processes, such as muscle contraction, protein synthesis, and active transport.
What joint actions occurring in a lateral raise during the concentric and eccentric phase?
To see eccentric contraction, look at the biceps curl with flexion around the elbow. As you lower a weight, you are working against resistance, letting the joint angle increase to lower that object under your control.The opposite is the concentric contraction were the arm is flexed upward to decrease the angle at the elbow.
