Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Methods: Participants will be recruited through invitations at work places and other community arenas. The investigators aim to recruit 10-15 subjects in each of the following age groups: 20-29, 30-39, 40-49, 50-59, 60-69 and 70-80 years of age. Both genders will be included. All age groups will be matched for age-related baseline maximal strength and distribution between the two genders. All participants will be checked via a health registration scheme, and excluded if contra indications for hard physical training or testing should appear. When in doubt, the projects physician will decide on inclusion or exclusion due to a thorough examination. Subjects will give a blood sample to be analyzed for known genes such as ACE and ACTN3. The intervention has a pre- post design. Tests of maximal strength and power will be conducted in a leg-press machine, using the protocol assessing one repetition maximum (1RM) previously described. Force and Power will be measured by the Muscle Lab system from Ergotest Tech. (Langesund, Norway). The intervention is an eight week, three times per week protocol, each training session consisting of a standardized warm-up, and 4 repetitions x 4 sets with an intensity of 4 repetition maximum (4RM) performed in the leg press machine.There will be a three minutes pause between sets. Participants will be given instructions and supervision.
Hypothesis: Maximal strength training adaptations will be affected by age and baseline maximal strength but not by gender or genetic variations.
