Strength training in seniors: The knowledge of positive aspects of eccentric training in elderly is sparse

Eccentric (lengthening) resistance training respectively muscle work requires a lower share of cardiac activity in comparison to concentric (shortening) muscle work. Especially in seniors suffering from cardiovascular diseases (still the most common cause of death in industrialized countries) this kind of activity is predisposed due to its possibility of high stimulation of musculoskeletal system only partly (20-25%) stimulating cardiovascular system. Comprehension of positive aspects was addressed for a sample of people doing regular work out while having access to concentric and eccentric training stations. 38 females (57 ± 15.7 years / 163.3 ± 19.4 cm / 63.6 ± 10.4 kg) and 36 males (57.6 ± 16.9 years / 177.4 ± 6.9 cm / 80.6 ± 8.7 kg) visiting at least once a week a fitness mall with access to eccentric and concentric training stations were asked concerning cardiovascular diseases, their corresponding risk factors and their own experience with eccentric muscle training. Differences in the perception of eccentric muscle training compared to concentric training were reported by 18 women and 24 men, however reported Rates of perceived Exertion measured by BORG-Scale (6-20) did not significantly differ. A positive Bias that especially persons with cardiovascular illnesses respectively risk factors preferred this kind of activity was not detectable and knowledge of positive aspects of eccentric training was sparse. General practitioners are encouraged to inform patients of the existence of positive aspects of eccentric muscle training and to motivate patients to absolve their training respectively
