## Question

How can sports-science HIIT evidence inform effective and time-efficient pre-surgical exercise interventions?

## Summary

This commentary argues that individually prescribed and supervised high-intensity interval training may be useful for short pre-surgical exercise programs. It does not report a new trial; its main value is practical guidance on frequency, intensity, time, type, progression, monitoring, and clinical safety boundaries.

## Population

- No original sample; target population is pre-surgical patients considered for prehabilitation.
- Fitness level: Varied; individual prescription emphasized
- Health status: Pre-surgical clinical population

## Methodology

- Commentary and narrative synthesis
- Pre-surgical exercise intervention planning

## Protocol

- Proposed pre-surgical HIT.
- Modality: Cycling, treadmill, upper/lower body, or functional exercise.
- Work intervals: Examples include 4 min or 30-60 s intervals.
- Recovery: Examples include 3 min active recovery for 4 x 4-min intervals.
- Sets or repetitions: Examples include 4 x 4 min or 4-6 x 30-60 s.
- Intensity: Typically >=90% HRmax; RPE also recommended.
- Frequency: No single prescription; vigorous guideline comparison mentions 3 sessions/week.
- Program length: Pre-surgical window may be short, such as about 4 weeks.
- Progression: Change one FITT-VP variable at a time.

## Outcomes

### Programming guidance
Status: unclear
The authors argue supervised, individualized HIT may be useful before surgery, but no original outcome data are reported.

## Practical Insights

- Clinical HIIT content should emphasize clearance, supervision, warm-up, monitoring, and conservative progression.
- RPE is important when medication makes heart-rate targets unreliable.
- Pre-surgical HIIT should not be framed as general self-guided advice.

## Limitations

- Commentary rather than original intervention research.
- No exact tested protocol or adverse-event data.
- No direct surgical recovery outcome data.

## Safety And Adherence

- No original adverse events were reported because this was a commentary.
- The authors recommend HIT only for clinically stable patients with recent regular moderate-intensity exercise exposure.
- They recommend adequate warm-up, relative intensity prescription, appropriate facilities, supervision, and monitoring during and after sessions.
