Sample Answer:

Judgement Statement:

  • Neurological adaptations prove highly effective in improving tennis performance, meeting criteria of skill refinement and performance consistency.

Skill Refinement:

  • Nerve pathways become better insulated through myelination, making signals travel faster for precise strokes.
  • Repeated practice creates automatic movement patterns in the brain for each stroke type.
  • Visual processing improves, helping players track the ball better and predict opponent shots.
  • The cerebellum gets better at timing movements, producing consistent contact points regardless of ball speed.
  • These changes result in measurable improvements in shot accuracy and power, with players making fewer unforced errors.

Performance Consistency:

  • Automatic movement patterns help maintain consistency by reducing how much players need to think during matches.
  • Less conscious thinking about technique allows focus on tactics and game strategy.
  • Players can repeat shots more accurately under pressure because they sense their body position better.
  • However, stress can still disrupt these automatic patterns in competition, especially in tie-breaks.
  • Neural adaptations show limitations when tiredness affects concentration in long matches.
  • Environmental factors like wind or crowd noise can interfere with established movement patterns.

Final Evaluation:

  • Neural adaptations greatly improve tennis performance by making skills more precise and automatic.
  • These adaptations strongly meet technical improvement goals but only partly meet consistency goals because pressure and tiredness still affect performance.
  • The benefits are much greater than the problems because neural changes create lasting improvements that stay even when players take breaks from training.
  • Players need to add mental training and fitness work to get the best results from their neural improvements.

Describe how the nervous system controls movement in power activities versus endurance activities.   (5 marks)

--- 15 WORK AREA LINES (style=lined) ---

Sample Answer

Power Activities:

  • Rapid recruitment of fast-twitch motor units through high-frequency neural signals for maximal drive.
  • Motor cortex sends maximal stimulation to activate large numbers of muscle fibres simultaneously within milliseconds.
  • High threshold motor neurons fire to generate explosive force production with immediate total recruitment.
  • Sympathetic nervous system maximally activated for immediate energy release, increasing adrenaline and glucose availability.
  • Short duration neural firing patterns prevent fatigue of neural pathways but cause rapid.

Endurance Activities:

  • Gradual recruitment of slow-twitch motor units through low-frequency neural signals for submaximal sustained activation.
  • Motor cortex maintains steady, submaximal stimulation over extended periods through efficient neural coding.
  • Low threshold motor neurons fire first, with systematic rotation of active motor units delaying fatigue.
  • Parasympathetic influence helps maintain efficient heart rate and breathing rhythm, optimising oxygen delivery.
  • Sustained neural firing patterns with motor unit rotation manage fatigue through gradual, rotating recruitment strategies.

Evaluate how fatigue affects the nervous system's ability to maintain skilled performance in endurance events.   (8 marks)

Sample Answer

Judgment Statement

  • Fatigue severely compromises the nervous system’s ability to maintain skilled performance in endurance events.
  • The nervous system strongly fails movement quality standards but partially maintains the ability to continue performing.

Movement Quality

  • Fatigue in the brain severely reduces movement quality by weakening the signals sent to muscles.
  • Marathon runners show deteriorating running form after 30km because fewer muscle fibres get activated.
  • Nerve chemicals work less effectively, making movements jerky instead of smooth.
  • Coordination suffers badly – cyclists begin wobbling and swimmers lose stroke rhythm.
  • Reaction times slow dramatically, with triathletes taking longer to respond to course changes.
  • These effects demonstrate that fatigue severely damages the precision needed for skilled movement.

Performance Continuation

  • Even though movement quality drops, the nervous system finds ways to keep athletes going.
  • They increase conscious thought to technique, though this uses mental energy.
  • Movement patterns change to work around tired muscles – runners shorten their stride to keep going.
  • Athletes rely more on watching their movements rather than feeling them.
  • Slower nerve signals mean reflexes work poorly, increasing injury risk.
  • However, these adaptations allow athletes to continue, even with reduced skill levels.

Final Evaluation

  • Fatigue profoundly impairs the nervous system’s control of skilled movement, with quality declining far more than the ability to continue.
  • While these backup strategies enable athletes to complete events, they cannot prevent significant skill deterioration.
  • The nervous system prioritises survival over performance quality when fatigued.
  • Success in endurance events requires training to delay these fatigue effects rather than relying on compensatory strategies.

During a tennis serve, what is the correct sequence of nervous system processes?

  1. Motor response → Processing → Sensory input
  2. Processing → Sensory input → Motor response
  3. Sensory input → Processing → Motor response
  4. Sensory input → Motor response → Processing
Show Answers Only

\(C\)

Show Worked Solution
  • C is correct: This sequence involves receiving sensory information (seeing the ball), processing in the central nervous system, then sending motor signals to muscles.

Other Options:

  • A is incorrect: Incorrect sequence – Output cannot occur before processing.
  • B is incorrect: Processing cannot occur before receiving sensory input.
  • D is incorrect: Processing must occur between input and output for coordinated movement.
