Muscle Memory
These are the three types of muscle tissue found in the human body.
What are skeletal, smooth, and cardiac muscle?
Commonly called the “abs,” this muscle is located at the front of the abdomen and helps bend the trunk forward.
What is the rectus abdominis?
This is the term for the main muscle responsible for producing a particular movement.
What is the agonist?
This term describes an increase in muscle fibre size, commonly resulting from resistance training.
What is muscle hypertrophy?
This is the common name for a sudden, painful muscle cramp, especially in the calf.
What is a charley horse?
This type of muscle is voluntary and attaches to bones to produce movement.
What is skeletal muscle?
This large muscle covers the shoulder and is responsible for raising the arm away from the body.
What is the deltoid?
This muscle acts as the antagonist when the biceps brachii bends the elbow.
What is the triceps brachii?
After wearing a leg cast for six weeks, a person's leg muscles become smaller and weaker. This process is called this.
What is muscle atrophy?
This muscle injury occurs when muscle fibres are overstretched or torn, often during sudden or forceful movements.
What is a muscle strain?
This tough connective tissue attaches muscles to bones, unlike ligaments, which connect bones to other bones.
What is a tendon?
Located at the back of the upper arm, this muscle is responsible for straightening the elbow.
What is the triceps brachii?
When a person kicks a soccer ball by straightening their knee, this muscle group acts as the agonist, while the hamstrings act as the antagonist.
What are the quadriceps?
This molecule provides the energy muscles need to contract and must constantly be replenished during exercise.
What is ATP (adenosine triphosphate)?
A hockey player takes a hard knee to the thigh, causing pain, swelling, and bruising. This injury is known as this.
What is a muscle contusion?
During a biceps curl, holding a dumbbell completely still while maintaining muscle tension is an example of this type of contraction.
What is an isometric contraction?
This large muscle covers much of the middle and lower back and helps pull the arm downward and backward.
What is the latissimus dorsi?
During an elbow extension, the triceps become the agonist and this muscle group becomes the antagonist.
What are the biceps?
During intense exercise, muscles break down glucose quickly, producing this substance that can also be reused by the body as an energy source.
What is lactate?
A student completes an intense leg workout on Monday. By Wednesday, their quadriceps are stiff and sore, especially when walking downstairs. This condition is responsible for the delayed soreness.
What is delayed onset muscle soreness (DOMS)?
During a biceps curl, the muscle shortens as the weight is lifted and lengthens under tension as the weight is slowly lowered. Name these two types of contractions in order.
What are concentric and eccentric contractions?
Located on the front of the lower leg alongside the shin, this muscle pulls the foot upward toward the shin during walking.
What is the tibialis anterior?
When a basketball player rises onto their toes to shoot, this calf muscle acts as a main agonist, while the tibialis anterior acts as the antagonist.
What is the gastrocnemius?
During a push-up competition, a student's arms begin shaking, their movements slow down, and eventually they cannot complete another repetition. This temporary decrease in the muscles' ability to produce force is called this.
What is muscle fatigue?
When a sprinter suffers a muscle injury that results in a complete tear of the muscle or muscle-tendon unit it is categorized as this.
What is a Grade 3 muscle strain?
