Tiivistelmä
The objective of the thesis was to study whether maximum voluntary isometric contraction (MVIC) values can be converted to one repetition maximum values (1RM) with a high degree of reliability in order to develop a mathematical formula for the conversion. An additional objective was to examine the relationship between 1RM and isometric
muscle strength using exercise devices.
The study participants comprised of healthy, trained men (n = 6) and women (n = 9). 1RM and MVIC tests were carried out at the Nordic Health clinic located in Helsinki using David Health Solutions’ exercise devices. Data was collected from 20 different exercises. The collected data was analyzed using Microsoft Excel and a statistical mathematics add-on.
As a result of this thesis, a strong correlation between 1RM and MVIC values was found (0,89). Additionally, a formula to estimate a person’s 1RM based on the results of the isometric muscle strength measurement was developed.
