简要总结
Exercise training is a cornerstone in the prevention and rehabilitation of cardiovascular disease. While research has primarily focused on endurance training, resistance training becomes more and more important. The gold standard to prescribe resistance training intensity or monitor longitudinal changes is the 1-Repetition-Maximum (1-RM) test. However, particularly for unexperienced individuals, this test may not be recommendable due to the high load and an increased risk of injuries. Alternatively, there are several published formulas to estimate the 1-RM based on a multiple-repetition-maximum (or repetition-to-failure) test. However, these formulas have been primarily tested in healthy individuals. Moreover, the reliability of the 1-RM estimation based on two tests with different submaximal weight is unknown. Therefore, the present study evaluates the agreement of the 1-RM estimation (based on different formulas) between two Multiple-RM tests with different weight in 50 patients with cardiovascular disease (heart failure, coronary heart disease, atrial fibrillation) or cardiovascular risk factors (type 2 diabetes, arterial hypertension).

结局指标
主要结局
Estimated 1-Repetition-Maximum
时间窗: cross-sectional study (day 1)
The estimated 1-Repetition-Maximums based on two Multiple-Repetition-Maximum tests with different weight will be compared using Bland-Altman plots. Acceptable Limits of Agreement are defined as +/- 10%. The comparisons will be performed using different published formulas to evaluate, which formula(s) may be recommended in patients with cardiovascular disease / risk factors. The study will be performed on the following resistance training machines: leg press and chest press
次要结局
- Number of repetitions required to perform a valid Multiple-Repetition-Maximum test(cross-sectional (day 1))
- Adverse Events(cross-sectional (day 1))
