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).",[36,37,38,39,40],"Heart Failure","Coronary Heart Disease (CHD)","Atrial Fibrillation (AF)","Diabetes Mellitus","Arterial Hypertension",[42,43,44,45],"resistance training","cardiovascular disease","cardiovascular risk factors","muscle strength","NOT_YET_RECRUITING","2025-01-27",{"date":49,"type":50},"2025-01-29","ACTUAL",{"date":52,"type":32},"2025-02",{"date":54,"type":32},"2025-06",{"name":5,"class":6}]
