Training background has a strong effect on maximal muscle strength and power, but aging causes a decline in these attributes. It is unclear how much of the deterioration is due to disuse of the muscles and how much to aging itself. The aim of this thesis was to assess how training background and age affect the force generation of healthy males.\n\nMethods\nFor this cross-sectional study speed, strength and endurance athletes and healthy controls of\ndifferent ages were recruited. Subjects formed two age-groups: young, aged 20-40 (n=104), and old, aged 60-80 (n=181). Maximal strength was measured via an isometric leg press and the use of bench press equipment and muscle power in a counter movement jump test.\n\nResults\nThe young\nIn isometric leg press, strength athletes (3842 N) were stronger than other groups (p<0.001). Speed group (2897 N) was stronger than endurance group (p<0.05). In bench press strength athletes (1541 N) were stronger than other groups (p<0.01). Speed athletes (1303 N) were stronger than endurance group or controls (p<0.001). In countermovement jump speed (44,2 cm) and strength (41,2 cm) groups jumped higher than endurance athletes or controls (p<0.01). Endurance athletes (35,9 cm) jumped higher than controls (31,0 cm) (p<0.01).\n\nThe old\nIn the isometric leg press test, strength athletes (2478 N) were stronger than endurance (2011 N) and control group (1807 N) subjects (p<0.05). In the bench press, strength athletes (966 N) were stronger than other groups (p<0.001). In countermovement jump, speed (26,4 cm) and strength groups (24,4 cm) jumped higher than endurance athletes (19,8 cm) or control group subjects (16,7 cm) (p<0.01).\n\nConclusions\nBoth speed and strength training hinder the deterioration of maximal strength and muscle power of the legs in aging male athletes compared to the decline in healthy control groups. Endurance training seems to be less effective in helping to retain muscle power and strength.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2020-09-04T05:48:35Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2020-09-04T05:48:35Z (GMT).
