As climbers, we often get carried away by our sensations on the rock or in the gym. We feel stronger, or that we lack endurance, but how do we really know if we’re progressing? Are we training the right things? The answer lies in the objective and periodic assessment of our physical qualities. Beyond perceptions, measuring our performance is a powerful tool that can transform our training and, ultimately, our climbing results.

In this post, we’ll break down the importance of assessments, the key criteria that tests must meet, and how, as climbers and coaches, we can use them to climb smarter and more effectively.

Why measure in climbing?

Assessing physical qualities in climbing is fundamental for several reasons:

It allows us to evaluate the level of development of physical performance factors, which are crucial for performing well in climbing.
It helps identify areas for improvement and guide training effectively, answering the big question: "What should I train?"
It facilitates measuring the effects of training and our progress, giving us a clear view of whether our planning is working.
It allows us to contextualize our performance in relation to our efficiency level and compare ourselves with other athletes of similar performance.

Objective assessments allow us to estimate how we’re improving a physical quality, regardless of temporary fluctuations in our performance. Moreover, by quantifying, we avoid cognitive biases and demystify beliefs like “I do this because it works for Adam,” helping us base our decisions on concrete data.

The precision of measurement: understanding error

When we measure, we’re comparing to a standard, and every measurement has a margin of error or “tolerance.” For example, if our ruler has 1 mm marks, the error will be +/-0.5 mm. Although the concept of measurement error is complex, it’s important to keep in mind that it always exists.

The pillars of a good test: essential requirements

For assessments to be truly useful, precise, and relevant, the tests we use must meet a series of fundamental requirements:

Relevance: The test must have a direct and significant relationship with climbing performance. For example, a test that assesses finger strength or specific endurance will be more relevant than one of explosive lower body strength for a climber.
Validity: Refers to the degree to which scientific evidence and theory support the interpretations of the tests. Validity is not a characteristic of the test itself, but of the interpretation of its results.
- Construct Validity: The test must really measure what it intends to measure. For example, a hand dynamometer that measures total grip strength may not be valid for climbers because it doesn’t discriminate between them and other people with strong hands (e.g., from tool use), as it doesn’t mimic the specific climbing grip.
- Criterion Validity: Once construct validity is established, this refers to the correlation between the test score and actual climbing performance. Valid tests are those whose values correlate with climbing level, usually expressed by the Pearson correlation coefficient (R).

Validity is crucial because it ensures that the conclusions of the assessments are appropriate and truly reflect the aspect of performance we want to measure.

Reliability: High validity requires high reliability. Reliability refers to the consistency of the measurement; that is, that a test provides similar or identical results when applied to the same person at two close moments and under the same conditions. It is measured with the intraclass correlation coefficient (ICC).
- To ensure reliability, it’s essential to apply a consistent and standardized measurement protocol and consider the participant’s condition.
- A reliable test ensures that results are not influenced by external variables, allowing for precise interpretation. It is a fundamental requirement for results to be valid and allows us to estimate measurement error.
Specificity: This is a crucial element related to validity. Specificity means that the test conditions resemble the real action being evaluated in climbing. Measuring grip strength on a crimp or two-finger pocket is more specific and relevant than using a hand dynamometer, as it better replicates the sport’s demands.

The coach’s role and athlete safety

It’s not only about what and how we measure, but also whom, when, and how we communicate the results.

Coherence-Prophylaxis (Safety): It’s essential to ensure the safety and health of participants, especially in young populations. Finger strength assessments in youth during the “growth spurt” (peak height velocity) carry a higher risk of injuries to the growth plates. Therefore, it’s imperative to discriminate which tests are safe for each population.
Regular Interval Repetition: Assessments should be scheduled periodically and when the climber is not fatigued. This helps athletes understand that data are tools for long-term improvement, relieves pressure on immediate results, and ensures that measurements reflect real adaptations, not fatigue.
Interpretation of Results: It’s crucial to provide athletes with accurate and timely information about their progress. Physiological tests can be physically and psychologically demanding, and communicating improvements effectively is essential to maintain motivation and ensure the athlete gives their best effort in each assessment.

Key factors influencing assessment results

When conducting tests, it’s vital to consider certain elements that can affect results:

Environmental Conditions: Temperature and humidity can significantly influence results, especially in endurance tests. Documenting these conditions is important for interpreting results.
Skin Condition: Sweating and hand moisture can affect grip ability, causing slippage, especially in long-duration endurance tests. This is less critical in short-duration strength tests.
Fatigue: Tests should be performed in a state of consistent recovery or with minimal fatigue. Fatigue can make observable adaptations appear lower than they really are, distorting results.

Conclusion

Objective and periodic assessments are a cornerstone of intelligent climbing training. They provide valuable data to identify our strengths and weaknesses, adjust our planning, measure our progress, and ensure we’re training as safely and effectively as possible. By understanding and applying the principles of relevance, validity, reliability, and specificity, and considering the factors that can influence results, we can turn “feeling” into “knowing” and thus unlock our full potential on the wall!
