Systematic use of resistance to increase the capacity of skeletal muscles to exert force
requires muscles to work against a resistance greater than normal to stimulate adaptation
dictates that training must match the desired outcome (strength, power, or endurance)
involves gradually increasing the weight, frequency, or number of repetitions to continually challenge muscles
Types of strength
represents the highest force a muscle can generate in a single maximal contraction
refers to strength in relation to body weight, crucial in sports like gymnastics
(power) combines force and speed, essential for activities like jumping or sprinting
allows sustained force production over time, important in sports like rowing or wrestling
Physiological adaptations
occur first, improving and firing frequency
(muscle growth) follows, increasing muscle fiber size and overall muscle cross-sectional area
Increased results from the stress placed on the skeletal system
Hormonal changes include elevated levels of and , promoting muscle growth and repair
Power training concepts
Power training focuses on developing the ability to exert maximum force in the shortest time possible
Crucial for explosive sports and activities requiring quick, forceful movements
Incorporates elements of both strength and speed training to optimize athletic performance
Power vs strength
Power combines force and velocity, expressed as work done per unit of time
Strength emphasizes maximum force production without time constraints
Power training typically involves lighter loads moved at higher speeds compared to traditional strength training
Strength serves as a foundation for power development, but high strength doesn't always translate to high
Rate of force development
Measures how quickly an athlete can produce force, critical for explosive movements
Influenced by neural factors such as motor unit recruitment and firing frequency
Improved through , , and methods
RFD can be sport-specific, with different requirements for various athletic activities (sprinting vs. throwing)
