Monitoring Internal Load SPS3114 Flashcards

What is Internal Load?

  • Internal load refers to the relative physiological stress placed on an athlete during training.

Monitoring Internal Load

  • Importance of understanding technology in monitoring:

    • Avoid being misled by technological advancements.

    • Interpret data based on actual events.

    • Formulate strategies for measurement, while tactics determine how to measure.

Smallest Worthwhile Change

  • Definition:

    • The minimal beneficial change in performance that is justifiable based on fitness tests.

    • Calculation: ext{Smallest Worthwhile Change} = 0.20 imes ext{Standard Deviation of Test Result Differences}

  • In team sports:

    • Default value is one-fifth of the between-athlete standard deviation.

Noise in Test Results

  • Noise is defined as the typical or standard error of measurement from reliability studies.

  • Generally, the noise exceeds the smallest worthwhile change.

  • Calculation of Noise:

    • ext{Typical Error} = rac{ ext{Standard Deviation of Test Results}}{1.41}

  • Actual meaningful change is computed as:

    • ext{Actual Meaningful Change} = ext{Typical Error} + ext{Smallest Worthwhile Change}

Monitoring Metrics

Subjective Scale Assessment

  • Rate of Perceived Exertion (RPE):

    • Highly correlated to heart rate and lactate levels.

    • Benefits of sRPE:

    • Cost-free, straightforward, and quick to implement.

    • Limitations:

    • Difficult to get honest responses from athletes.

    • Confusion regarding the scale’s use.

Training Load Calculations

  • Training Load: ext{Training Load} = ext{RPE} imes ext{Session Duration}

  • Monotony Indicator: ext{Monotony} = rac{ ext{Training Load}}{ ext{StDevTL}}

  • Training Strain: ext{Training Strain} = ext{Training Load for the Week} imes ext{Monotony}

Acute vs. Chronic Load

  • Current debate over acute/chronic workload ratio:

    • Previous positive reception is now challenged by recent findings suggesting it yields negligible results.

    • Recommendation is to focus on load assessment trends.

Engagement in Monitoring

  • Importance of athlete engagement in assessments:

    • Commitment to provide authentic responses.

    • Use of variations in questions to keep responses genuine.

  • Wellness questionnaires can measure a range of factors:

    • Personal issues, perceived recovery, fatigue, sleep quality.

Heart Rate Variability (HRV) Assessment

  • Factors affecting HRV assessments:

    • Previous activities, time of day, body posture, and diet.

Submaximal Assessment Techniques

  • Submax YoYoIR2:

    • Involves assessing maximum heart rate and recovery patterns after exercise.

  • Treadmill Test:

    • Designed to meet logistical requirements.

Range of Motion Measurements

  • Techniques:

    • Sit & reach, knee-to-wall, Thomas Test.

  • Applications of measurement:

    • Determine bilateral and unilateral deficits.

Review Questions

  • What is Internal Load?

  • Goals of Monitoring Internal Load?

  • Definitions for smallest worthwhile change, noise in test results, actual change required, and internal load measures.

  • Discuss the advantages and limitations of sRPE, wellness questionnaires, HRV training, and biochemical markers.

  • Define unilateral and bilateral deficit in range of motion measurements.

Additional Review Questions

  • What does internal load refer to in the context of athletic training?

    • Internal load refers to the relative physiological stress placed on an athlete during training.

  • Why is it important to understand technology when monitoring internal load?

    • To avoid being misled by technological advancements, interpret data based on actual events, and formulate effective measurement strategies.

  • How is the Smallest Worthwhile Change calculated, and what does it represent?

    • ext{Smallest Worthwhile Change} = 0.20 imes ext{Standard Deviation of Test Result Differences} . It represents the minimal beneficial change in performance that is justifiable based on fitness tests.

  • Define noise in the context of test results and provide its calculation.

    • Noise is the typical or standard error of measurement from reliability studies. Calculation: ext{Typical Error} = \frac{\text{Standard Deviation of Test Results}}{1.41}

  • How is "Actual Meaningful Change" computed, and why is it important?

    • ext{Actual Meaningful Change} = ext{Typical Error} + ext{Smallest Worthwhile Change}. It helps determine the real change beyond just the noise and minimal worthwhile change.

  • What are the benefits and limitations of using the Rate of Perceived Exertion (RPE) as a subjective scale assessment?

    • Benefits: Cost-free, straightforward, and quick to implement. Limitations: Difficult to get honest responses, confusion regarding scale use.

  • Explain how training load, monotony, and training strain are calculated.

    • Training Load: ext{Training Load} = ext{RPE} imes ext{Session Duration}, Monotony: ext{Monotony} = \frac{\text{Training Load}}{\text{StDevTL}}, Training Strain: ext{Training Strain} = ext{Training Load for the Week} imes ext{Monotony}

  • What is the current debate surrounding the acute/chronic workload ratio, and what is the recommendation?

    • Previous positive reception is now challenged by recent findings suggesting it yields negligible results. Recommendation is to focus on load assessment trends.

  • Why is athlete engagement important in monitoring assessments, and what tools can be used to enhance this engagement?

    • Commitment to provide genuine responses. Use variations in questions and wellness questionnaires to measure personal issues, perceived recovery, fatigue, and sleep quality.

  • What factors can affect Heart Rate Variability (HRV) assessments, and how can these be controlled?

  • Factors that affect Heart Rate Variability (HRV) assessments include previous activities, time of day, body posture, and diet. These can be controlled by standardizing measurement conditions, such as measuring HRV at the same time each day,
