Key result
The 10 m incremental shuttle walk test showed a moderate to high association with symptom-limited exercise test duration (r2 ⩾0.72) but cannot reliably predict individual test duration.
Why the study?
Does the 10 m incremental shuttle walk test accurately measure exercise capacity compared to a symptom-limited exercise test in patients eligible for cardiac rehabilitation?
RCT (n=15)
Randomized order of testing
Does the 10 m incremental shuttle walk test accurately measure exercise capacity compared to a symptom-limited exercise test in patients eligible for cardiac rehabilitation?
Effect estimate: r2 ⩾0.72
The 10 m incremental shuttle walk test is a convenient field test of exercise capacity in cardiac rehabilitation but cannot accurately predict individual symptom-limited exercise test duration.
No takes yet. Share an insight, caveat, or question.
ISWT should not guide individual exercise capacity assessment in cardiac rehab; leaves open group-level utility pending prospective validation.
Hanson et al. (2017) conducted an RCT in Cardiac rehabilitation (n=15). 10 m incremental shuttle walk test (ISWT) vs. Treadmill symptom-limited exercise test was evaluated on Association between ISWT and symptom-limited exercise test duration (r2 ⩾0.72). The 10 m incremental shuttle walk test showed a moderate to high association with symptom-limited exercise test duration (r2 ⩾0.72) but cannot reliably predict individual test duration.
