• Biomechanical principles (force, velocity, power) form the foundation for designing effective sport-specific conditioning programs
• Specificity principle emphasizes training adaptations tailored to the type and manner of activity performed
• Kinetic chain analysis reveals the sequence of joint and muscle actions in sport-specific movements
  • Helps identify weak links in the movement chain
  • Enables targeted strengthening of specific muscle groups
• Force-velocity relationship guides power-specific training protocols for different sports
  • High force, low velocity for strength-based sports (powerlifting)
  • Low force, high velocity for speed-based sports (sprinting)
• Biomechanical analysis of sport-specific techniques pinpoints key areas for strength and conditioning focus
  • Identifies inefficiencies in movement patterns
  • Highlights areas requiring improved stability or mobility

Training Design and Progression

• Progressive overload principle directs gradual increase in training demands to improve performance
  • Incrementally increase weight, sets, reps, or movement complexity
  • Allows for continuous adaptation without overtraining
• Moment arms and lever systems knowledge aids in designing exercises targeting sport-specific muscle groups and movement patterns
  • Longer moment arms increase torque and muscle activation
  • Shorter moment arms decrease torque but increase speed of movement
• Plyometric training utilizes the stretch-shortening cycle to enhance power output
  • Improves rate of force development
  • Particularly beneficial for explosive sports (basketball, volleyball)
• Resistance training programs should mimic sport-specific force production patterns
  • Concentric-focused training for acceleration-based sports (sprinting)
  • Eccentric-focused training for deceleration-based sports (tennis, basketball)

Energy Systems in Sports

Primary Energy Systems and Their Contributions

• Three primary energy systems contribute differently to various sports based on duration and intensity
  • ATP-PC system: Immediate energy for short, explosive efforts (weightlifting, sprinting)
  • Glycolytic system: Short-term energy for intense efforts lasting 30 seconds to 2 minutes (400m run, wrestling)
  • Oxidative system: Long-term energy for endurance activities (marathon, cycling)
• Energy system continuum explains varying proportions of each system used throughout performance
  • Sprinting: Primarily ATP-PC at start, shifting to glycolytic as race progresses
  • Soccer: Alternates between all three systems during a match
• Metabolic specificity principle dictates training should match predominant energy systems used in a particular sport
  • High-intensity interval training for sports with repeated bursts of activity (basketball)
  • Long slow distance training for endurance-based sports (marathon running)

Muscle Characteristics and Actions

• Muscle fiber type composition influences an athlete's performance capabilities in specific sports
  • Slow-twitch (Type I) fibers: Fatigue-resistant, ideal for endurance sports (marathon running)
  • Fast-twitch (Type II) fibers: Powerful, suited for explosive sports (sprinting, weightlifting)
• Muscle actions play distinct roles in different sports and require specific training
  • Concentric actions: Muscle shortening (upward phase of a bicep curl)
  • Eccentric actions: Muscle lengthening under tension (lowering phase of a squat)
  • Isometric actions: Muscle tension without length change (plank hold)
• Rate of force development (RFD) crucial in explosive sports, requires specific training methods
  • Olympic lifts and plyometrics improve RFD
  • Essential for sports requiring quick bursts of power (boxing, sprinting)

Substrate Utilization and Nutritional Considerations

• Understanding substrate utilization during different sporting activities informs nutritional strategies
  • Carbohydrates: Primary fuel for high-intensity activities
  • Fats: Main energy source for low-intensity, long-duration activities
  • Proteins: Used minimally for energy, crucial for recovery and muscle repair
• Nutritional periodization aligns macronutrient intake with training phases and competition demands
  • Higher carbohydrate intake during intense training periods or before competitions
  • Increased protein intake during strength-focused training phases

Periodization for Performance

Fundamentals of Periodization

• Periodization systematically manipulates volume, intensity, and specificity over time to optimize performance and reduce injury risk
• General Adaptation Syndrome (GAS) forms the theoretical basis for periodization
  • Alarm phase: Initial response to training stress
  • Resistance phase: Body adapts to stress, improving performance
  • Exhaustion phase: Occurs if stress is too great or prolonged
• Different periodization models offer varied approaches to structuring training cycles
  • Linear periodization: Gradual progression from high volume, low intensity to low volume, high intensity
  • Undulating periodization: Frequent variations in volume and intensity
  • Block periodization: Focuses on developing specific abilities in concentrated blocks

Implementation and Benefits

• Periodization manages fatigue and recovery, preventing overtraining syndrome and reducing injury risk
  • Incorporates planned recovery periods
  • Alternates between high and low-intensity training phases
• Training phases allow for systematic progression and peaking at the right time
  • Preparatory phase: Builds general fitness and strength
  • Competitive phase: Focuses on sport-specific skills and performance
  • Transition phase: Active recovery and maintenance of fitness
• Facilitates integration of technical, tactical, and physical training components in a cohesive long-term plan
  • Aligns skill development with physical preparedness
  • Ensures all aspects of performance are addressed systematically
• Individualization principle emphasizes tailoring programs to athlete's specific needs, sport demands, and competition schedule
  • Considers factors like training age, injury history, and performance goals
  • Allows for flexibility in program design based on individual response to training

Strength vs Endurance Training

Concurrent Training and Integration

• Concurrent training addresses the challenge of developing strength, power, and endurance simultaneously without interference effects
  • Careful scheduling of different training modalities
  • Strategic use of recovery periods between different types of training
• Complex training methods enhance power development for explosive sports
  • Combines heavy resistance exercises with plyometrics (heavy squat followed by jump squats)
  • Utilizes post-activation potentiation to improve power output
• Strength training protocols tailored to sport-specific force production requirements
  • Eccentric overload training improves deceleration abilities (crucial in change-of-direction sports)
  • Variable resistance training (bands, chains) matches strength curve of specific movements

Endurance Training Methods

• High-intensity interval training (HIIT) and tempo runs customized to match aerobic and anaerobic demands of different sports
  • HIIT improves both aerobic and anaerobic capacity
  • Tempo runs enhance lactate threshold and running economy
• Transfer of training concept emphasizes selecting exercises and methods mimicking sport-specific movements and energy demands
  • Sport-specific plyometrics for jumping sports (basketball, volleyball)
  • Resisted sprints for acceleration improvement in field sports
• Periodized integration of strength, power, and endurance training manages fatigue and optimizes adaptations
  • Alternating focus on different physical qualities throughout training cycle
  • Careful consideration of recovery needs between different training modalities

Performance Monitoring and Program Adjustment

• Sport-specific performance testing protocols essential for monitoring training effectiveness
  • Vertical jump tests for lower body power
  • Yo-Yo intermittent recovery test for soccer-specific endurance
• Regular testing guides program adjustments and ensures continued progress
  • Identifies areas of improvement or plateau
  • Allows for timely modifications to training focus or methods
• Athlete monitoring tools (heart rate variability, perceived exertion) provide insights into recovery status and readiness to train
  • Helps prevent overtraining and optimize adaptation
  • Allows for individualized adjustments to training load
