Definitions Flashcards
Muscular Endurance
Focuses on prolonged muscle activity (holding or repeating actions)
Muscular Strength
involves the maximum force a muscle can generate in a single effort (heavy weightlifting)
Aerobic Power
The max rate at which the body can produce energy from oxygen during physical activity, it’s a measure how well the body’s systems work together to transport oxygen to the muscles
Cardiorespiratory performance (Aerobic Power)
The ability of the heart and lungs to pump oxygen to the muscles
Blood Oxygen Content (Aerobic Power)
The amount of blood pumped by the heart
Heart Rate (Aerobic Power)
The rate at which the heart pumps blood
Muscular Power
The ability of a muscle or group of muscles to exert a maximum amount of force in a short period of time. Examples of muscular power include fast leg kicks, explosive jumping, taking a big step and lifting your body while boarding a bus
Plyometric exercises (Muscular Power)
These exercises involve quick, repetitive movements, such as jumping and plyometric push ups
Isokinetic exercises (Muscular Power)
These exercises involve repetitive movements at a constant speed, while modifying the weight
Flexibility
The ability of a joint or series of joints to move through an unrestricted, pain free range of motion
Overload
Also known as progressive overload, is a training method that gradually increases the stress on your body to improve your strength and endurance
Specificity
Is a type of exercise that is designed to improve a specific skill or ability. The principle pf specificity states that the body adapts to the type of physical activity it performs, so the more the specific the exercise, the greater the improvement
Reversibility
The idea that fitness gains are lost when training stops. This can happen when training intensity decreases, or if an injury or illness prevents training, the effects of reversibility can be reversed by resuming training
Skeletal muscle
is a tissue that allows you to move, maintain posture, and regulate body temp. it’s found throughout the body and makes up about 40% of a person’s body weight
Cardiac Muscle
Also known as the myocardium, is the middle layer of the heart that pumps blood throughout the body. It’s made up of cardiomyocytes, which are individual cells that contract to generate the force needed to pump blood.
contraction
Cardiac muscle contracts and relaxes rapidly and involuntarily to pump blood.
Cardiac Output
The amount of blood pumped by the heart, which is determined by the heart and stroke volume.
Isometric contraction
Muscle length remains the same/contraction is held
Isotonic contraction
Both shortening and Lengthening of the muscle fibers
Smooth muscle
A type of involuntary muscle that lines the inside of hollow organs. It has many functions, including moving food through the digestive system, regulating blood pressure and helping the lungs expand
Cardiovascular disease
A general term for conditions affecting the heart for blood vessels
Pulmonary Disease
A disease that affects the lungs and respiratory system. It can be by infection, smoking or exposure to air pollution
Internal Motivation
Internal motivation to exercise is when you exercise because you enjoy the activity itself, rather than for a reward or outcome. It is a sustainable way to exercise that comes from your own values and goals
Examples: Enjoying the process of exercising, feeling good about taking care of your body, improving your health, increasing your energy, and reducing stress
External motivation
External motivations for exercise is when a person is motivated to exercise because of external factors, such as rewards, recognition, or avoiding negative consequences.
Examples: Weight loss, Social rewards, prizes & fitness challenges
