Tutkimukseen osallistuminen oli vapaaehtoista ja siihen saivat osallistua kaikki urheilijat jotka ottivat osaa kilpailuihin. Tasapaino- ja alaraajojen voimantuoton mittaukset suoritettiin onnistuneesti 62 naiselle ja 66 miehelle (n=128). Reaktionopeuden mittauksiin tutkimusjoukosta osallistui 43 naista ja 54 miest\u00e4 (n=97).

Problems in postural balance are common in older adults and they are strongly associated with increased risk of falling. Poor postural control is also associated with a person's psychosocial wellbeing when moving and social contacts are decreased because of fear of falling. The purpose of this study was to determine differences in leg muscle power, psychomotor speed and static postural balance between sprint/power disciplines and endurance disciplines in over 35-year-old master track- and field athletes. Also, purpose was to determine relation of muscle power and psychomotor speed to static postural balance.\n\nData were collected in WMA 2009. Participation in the study was based on voluntariness and everyone who participated to games was free to participate to study. Measurements of postural balance and maximum leg power were made in 62 women and 66 men (n=128). Measurements of psychomotor speed were made in 43 women and 54 men (n=97). Age was from 37 to 84 years in women (mean 57.2, SD 12.3), and from 37 to 91 years in men (mean 64.5, SD 15).\n\nBackground information was collected by interview before measurements. Measurements of postural balance and leg power were performed with forceplate (Force platform FP4, HUR labs, Tampere). In measurement of postural balance persons horizontal sway was measured by change of center of pressure (COP) and recorded as length of sway path in 30 seconds. Power of leg muscles was measured by a maximal countermovement jump. Measurements of reaction speed were conducted with dominant hand. Measurement device had a waiting button and 7 aim buttons 10 cm away from waiting button. Reaction speed was time from switch on of signal light to pressing of aim button. Reaction speed was measured with both, simple and seven choice tests. In analysis all data were standardized with age. \n\nIn sprint and strength disciplines men had 33% (p<.001) and women 38% (p<.001) better maximum leg power than endurance athletes. In men also reaction speed was 7% (p=.034) faster in sprint and strength disciplines than in endurance disciplines. In static postural balance there was no difference between groups. There was no relation between static postural balance and leg power or reaction speed.\n\nThe results show that intensive track- and field training in sprint and strength disciplines that has continued for long time is positively associated with leg power and might lead to a better simple choice reaction speed than training of endurance disciplines in track- and field. Leg power or reaction speed seems not to have relation to static postural balance in master track- and field athletes.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Antti Sillanp\u00e4\u00e4 (anjosill) on 2013-09-12 11:48:50.805759.
