The amount of effort you put into an exercise determines how your body adapts to it. More intense workouts lead to greater strength, power, and size gains.

Intensity in the weight room can be measured by the amount of weight lifted (load) and how hard you're working (perceived effort).

Refers to the large muscle groups in your body like your chest (pectoralis major), hamstrings (semitendinosus, semimembranosus), and glutes (gluteus maximus, minimus, and medius).

The internal structure of a muscle, starting with the muscle belly and zooming into the myofilaments (actin and myosin), which are responsible for muscle contraction.

The shortening of a muscle, pulling on tendons and bones to create movement. This happens at the microscopic level with actin and myosin interacting.

The point where a muscle attaches to the more stationary bone, usually closer to the center of the body.

The point where a muscle attaches to the bone that moves during contraction, typically further away from the body's midline.

An imaginary line dividing the body vertically into left and right halves.

The central, fleshy part of a muscle that contains the muscle fibers.

The outer layer of connective tissue that surrounds an entire muscle.

Bundles of muscle fibers within a muscle, wrapped in perimysium.

The connective tissue that surrounds individual muscle fibers within a fascicle.

The membrane that surrounds a single muscle fiber.

A long, cylindrical structure that makes up muscle fibers and contains the contractile proteins (actin and myosin).

The proteins within myofibrils that interact to cause muscle contraction.

Muscle fibers increase in size (hypertrophy) when subjected to resistance training, leading to overall muscle growth.

Concentric (shortening), eccentric (lengthening), and isometric (no change in length).

Concentric action involves shortening of the muscle, while eccentric action involves lengthening of the muscle.

A muscle action where the length of the muscle remains constant while force is produced.

The thin filament in a muscle fiber that is responsible for muscle contraction.

The thick filament in a muscle fiber that has heads that bind to actin and pull it.

Myosin heads attach to actin and pull it, causing the muscle fibers to shorten.

Parts of a sarcomere that represent the myosin and actin filaments, respectively.

A single motor neuron and all the muscle fibers it innervates.

The neuromuscular system transmits signals from the brain to the muscles, telling them to contract.

A motor neuron carries signals from the brain to the muscle fibers.

A single motor neuron can innervate (connect with) many muscle fibers, but each muscle fiber is controlled by only one motor neuron.

We need a vast network of motor neurons to control the trillions of muscle fibers in our bodies.

A motor neuron has dendrites, a nucleus, and an axon.

The space where a motor neuron connects to a muscle fiber, enabling communication for muscle contraction.

An electrical signal traveling along a neuron, triggering muscle contraction when reaching the neuromuscular junction.

Calcium and ATP are released at the neuromuscular junction, causing myosin and actin to interact, forming cross-bridges and resulting in muscle contraction.

Slow-twitch muscle fibers, primarily used for endurance activities, characterized by low force output and high fatigue resistance.

Fast-twitch muscle fibers, suited for both endurance and strength activities, moderate force output and fatigue resistance.

Fast-twitch muscle fibers, primarily used for explosive power and strength activities, high force output and low fatigue resistance.

Think of muscle fibers like cars: Type 1 = fuel-efficient economy car, Type 2A = sporty sedan, Type 2X = high-performance sports car.

A motor neuron and all the muscle fibers it innervates, working together to generate force.

The process by which a nerve (motor neuron) activates a muscle fiber.

Type 1 (slow-twitch), Type 2A (fast-twitch, moderate), Type 2X (fast-twitch, high-power) - each suited for different activities.

The overall shape and structure of a muscle, including its origin, insertion, and muscle belly.

Muscle fibers have specific properties like force output, fatigue resistance, and speed of contraction, determining their function.

Type 1 fibers are ideal for endurance, Type 2A are versatile, and Type 2X are best for explosive power, based on their properties.

Strength training offers numerous benefits, including increased calorie burning, muscle mass, bone density, and improved blood sugar control. It also enhances sleep, heart health, and overall quality of life.

Strength training is crucial for athletes in all sports. It increases power, speed, and endurance, leading to better performance on the field.

The resting metabolic rate is the number of calories your body burns at rest. Muscle mass increases your RMR, meaning you burn more calories even when doing nothing.

Squats and deadlifts strengthen muscles and bones, improving balance, mobility, and preventing falls, which are common among elderly people.

Muscles are made of fibers that contract and relax to produce movement. Strength training increases muscle fiber size and strength.

Multiple factors influence strength gains. These include genetics, training intensity, nutrition, and recovery.

Factors like training volume (sets and reps), nutrition, and genetics influence muscle growth. More volume and proper nutrition contribute to hypertrophy.

A basic program for improving health involves setting goals, choosing exercises, and determining the frequency, intensity, and duration of workouts.

The body is made up of different muscle groups, such as the legs, back, chest, arms, and core. Each group has specific exercises to target.

Beginners should train 2-3 days a week with at least 48 hours of rest between sessions to allow muscle recovery.

DOMS is a common muscle soreness that occurs 12-72 hours after a new or intense workout. It's a sign of muscle adaptation.

Sets are groups of repetitions. Reps are how many times you perform an exercise.

Two organizations with different training guidelines. ACSM is for beginners, NSCA for intermediate and advanced.

To increase strength, do fewer reps (1-8) with heavier weight.

To build muscle size, do more reps (8-15) with moderate weight.

To increase muscular endurance, do many reps (more than 15) with lighter weights.

Longer rest periods (2-5 minutes) are needed for strength training.
