Classroom Exercise Frequency and Mental Health in Medical Students
5 augusti 2026 uppdaterad av: Dynamical Business and Science Society - DBSS International SAS
Promoción de la Actividad física y la Salud Mental en Estudiantes de Medicina
This 16-week, three-group, nonrandomized interventional study evaluated whether the weekly frequency of a brief classroom-based physical exercise program was associated with changes in mental health and physical activity among 105 undergraduate medical students at Universidad Tecnologica de Pereira, Colombia.
EG2 (n=35) received two exercise sessions per week, EG1 (n=37) received one session per week, and CG (n=33) received no exercise intervention.
Anxiety, depression, stress, and physical activity were assessed at baseline and after 16 weeks.

Detaljerad beskrivning
The three groups were specified prospectively in the ethics-approved protocol.
Participation was voluntary, and all participants completed written informed consent.
Academic groups were formed independently of the investigators by the university Registration and Academic Control Unit through its routine enrollment process.
Both intervention groups received the same approximately 10-minute classroom exercise program and differed only in weekly frequency.
Each session comprised a 3-minute warm-up, a 5-minute interval circuit involving large muscle groups, and a 2-minute cool-down with stretching and breathing.
Exercises varied across sessions and intensity increased progressively.
The target intensity was 5 to 7 on the modified 0-to-10 Borg scale together with a moderate Talk Test response.
Attendance was called before each session by the assigned instructor, and withdrawal during a session was recorded.
Adherence was defined as attendance at 80% or more of delivered sessions.
No adverse events were recorded.

Experimentell: EG2 - Classroom Exercise Twice Weekly
Thirty-five participants received two approximately 10-minute classroom exercise sessions per week for 16 weeks, corresponding to 32 delivered sessions.
|
Approximately 10-minute sessions comprising a 3-minute warm-up, a 5-minute interval circuit involving large muscle groups, and a 2-minute cool-down.
Exercises varied and intensity increased progressively, targeting 5 to 7 on the modified 0-to-10 Borg scale and a moderate Talk Test response.
The program required no exercise equipment.

Experimentell: EG1 - Classroom Exercise Once Weekly
Thirty-seven participants received one approximately 10-minute classroom exercise session per week for 16 weeks, corresponding to 16 delivered sessions.
|
Approximately 10-minute sessions comprising a 3-minute warm-up, a 5-minute interval circuit involving large muscle groups, and a 2-minute cool-down.
Exercises varied and intensity increased progressively, targeting 5 to 7 on the modified 0-to-10 Borg scale and a moderate Talk Test response.
The program required no exercise equipment.
