Muscular System
What are muscles responsible for in the body?
Muscles are responsible for producing movement, maintaining posture, and helping with body functions like breathing and digestion.
What is the main function of the skeleton in the human body?
The main function of the skeleton is to provide structure and support for the body. It also protects vital organs, helps with movement, stores minerals, and produces blood cells.
What is the function of the heart?
he heart pumps blood throughout the body. It sends oxygenated blood to the body and deoxygenated blood to the lungs for oxygenation.
uring a barbell front squat, which muscle plays a significant role in stabilizing the torso and preventing it from collapsing forward?
Erector spinae
Which system does aerobic exercise primarily target?
Cardiovascular system
What is the difference between skeletal muscles and smooth muscles?
What is the longest bone in the human body?
The femur, also known as the thigh bone, is the longest bone in the human body.
What are the two different measurements of blood pressure?
What is the primary muscle worked during a barbell overhead press?
Deltoids
During a burpee, which muscle group is most engaged while jumping?
Quadriceps
What is the role of tendons in the muscular system?
Tendons are strong, fibrous tissues that connect muscles to bones. They help transmit the force generated by muscles to move the bones.
How many bones are in the adult human skeleton?
The adult human skeleton has 206 bones.
What are the main components of the cardiovascular system?
The main components of the cardiovascular system are the heart, blood vessels (arteries, veins, capillaries), and blood.
In a barbell back squat, which muscle group helps to extend the hip as you rise from the bottom of the squat?
Gluteus maximus
In sprints, what is the primary energy system that fuels short, intense efforts?
Phosphagen system (ATP-PCr system)
What happens when a muscle contracts?
When a muscle contracts, it becomes shorter and tighter, which helps the body move. For example, when you bend your arm, the muscle in your upper arm contracts.
What is the name of the bone in your upper arm?
The bone in your upper arm is called the humer
What is the main function of the cardiovascular system?
The main function of the cardiovascular system is to circulate blood throughout the body, delivering oxygen, nutrients, and hormones to cells and removing waste products like carbon dioxide.
What muscle is primarily responsible for generating force to extend the arms during a barbell bench press?
Triceps brachii
What is the primary cardiovascular benefit of tabata training?
Improved VO2 max
What is the role of ATP in muscle contraction?
ATP (adenosine triphosphate) provides the energy needed for muscle contraction. It helps myosin heads attach to actin filaments and detach after pulling, allowing the muscle to keep contracting. Without ATP, muscles cannot contract properly.
What are the three main types of joints, and how do they differ?
What is the difference between arteries and veins?
Which muscles are targeted when doing a barbell squat with pause at the bottom?
The primary muscles worked are the quadriceps, hamstrings, and glutes. Pausing at the bottom increases time under tension, particularly engaging the quadriceps and improving power and stability at the bottom of the squat.
What is the main fuel source for prolonged moderate-intensity exercise?
Fat
