Summary
This study validates single-item measures for fatigue and recovery in dancers, finding the fatigue item reliable and valid. The recovery item showed acceptable reliability but only partial construct validity.
Area of Science:
- Sports Medicine
- Dance Science
- Psychometrics
Background:
- Assessing dancer fatigue and recovery is crucial for performance and injury prevention.
- Validated, concise measurement tools are needed for efficient data collection in dancers.
Purpose of the Study:
- To evaluate the construct validity and reliability of two single-item measures for fatigue and recovery in dancers.
- To explore dancers' interpretation of these single items.
Main Methods:
- 243 dancers completed single-item fatigue/recovery, Brunel Mood Scale (BRUMS), and Short Recovery and Stress Scale (SRSS) for validity.
- 49 dancers completed questionnaires twice for reliability and underwent concept identification for interpretation.
Main Results:
- The fatigue item demonstrated good construct validity and reliability.
- The recovery item showed acceptable reliability but only partial construct validity.
- Dancers defined fatigue as tiredness and muscle soreness; recovery as muscle soreness and tiredness.
Conclusions:
- Single-item fatigue measures are preliminarily validated for dancers.
- The single-item recovery measure has acceptable reliability but requires further validation.
- Further research is needed to explore other measurement properties of these items.

Fatigue occurs when materials rupture under repeated or fluctuating loads, even at stress levels far below their static breaking strength. It typically results in brittle failure, even for ductile materials. It is a critical consideration in designing machines and structural components subjected to repetitive or varying loads. The nature of these loadings can range from fluctuating loads like unbalanced pump impellers causing vibrations to repeatedly bending a thin steel rod wire back and forth...

01:24Muscle Recovery and Fatigue
2.2K
Muscle fatigue refers to the decline in a muscle's ability to maintain the force of contraction after prolonged activity. It primarily stems from changes within muscle fibers. Even before experiencing muscle fatigue, one may feel tired and have the urge to stop the activity. This response, known as central fatigue, occurs due to changes in the central nervous system, namely the brain and spinal cord. While there is no single mechanism that induces fatigue, it may serve as a protective...
