Summary
Aerobics instructors frequently experience voice loss and hoarseness due to shouting and poor vocal hygiene knowledge. This study highlights occupational voice risks for fitness professionals.
Area of Science:
- Occupational Health
- Speech Science
- Kinesiology
Background:
- Fitness instructors, particularly in aerobics, are susceptible to voice disorders.
- High-intensity vocal demands in aerobics instruction pose occupational risks.
Purpose of the Study:
- To investigate the prevalence of vocal problems among aerobics instructors.
- To identify risk factors associated with voice disorders in this population.
- To assess instructors' knowledge of vocal hygiene.
Main Methods:
- A questionnaire was administered to 54 aerobics instructors (50 female, 4 male).
- Data collected included teaching experience, facility conditions, voice projection methods, music volume, health history, smoking habits, and vocal hygiene knowledge.
- Participants reported voice loss, hoarseness, and sore throat episodes.
Main Results:
- 44% of instructors reported partial or complete voice loss during or after instruction.
- Instructors experienced increased voice loss, hoarseness, and sore throat unrelated to illness since starting their careers.
- Sore throat and hoarseness post-instruction, and shouting to cue participants were significant risk factors.
- Vocal hygiene knowledge was notably low among participants.
Conclusions:
- Aerobics instruction is associated with a high prevalence of voice problems.
- Vocal strain from shouting and inadequate vocal hygiene knowledge contribute to these issues.
- Targeted interventions focusing on vocal training and hygiene are recommended for aerobics instructors.
