T\u00e4m\u00e4n lis\u00e4ksi tutkittiin aineenvaihdunnallisten muuttujien eroja ryhmien v\u00e4lill\u00e4. Tutkimus on ensimm\u00e4isi\u00e4 raportteja, miss\u00e4 \u00e4lyvaatteilla on mitattu lihasaktiivisuuksia useammilla eri k\u00e4vely- ja juoksunopeuksilla yhdistettyn\u00e4 hapenkulutusmittauksiin. Tutkimukseen osallistui yhteens\u00e4 21 vapaaehtoista, joista 20 suorittivat mittaukset ja joista 17 tulokset oli mahdollista analysoida. Juoksua harrastavien ryhm\u00e4ss\u00e4 oli 5 miest\u00e4 ja 5 naista ja harrastamattomien ryhm\u00e4ss\u00e4 oli 5 miest\u00e4 ja 2 naista. Tutkittavilta mitattiin maksimaalinen tahdonalainen isometrinen lihasaktiivisuus (MVIC) pintaelektrodi elektromyografiaa (sEMG) hy\u00f6dynt\u00e4vill\u00e4 \u00e4lyvaateilla etureisist\u00e4, takareisist\u00e4, pakaroista, kaksoiskantalihaksista, leveist\u00e4 kantalihaksista ja etummaisilta s\u00e4\u00e4rilihaksilta. Tutkittavat k\u00e4veliv\u00e4t 1,0 m/s, 1,3 m/s ja 1,5 m/s sek\u00e4 juoksivat 2,2 m/s, 2,5 m/s, 2,8 m/s, 3,1 m/s ja 3,3 m/s nopeuksilla viiden minuutin kuormitusjaksoja 200 metrin ulkoradalla valoj\u00e4niksen ohjaamalla nopeudella. Kuormitusjaksojen aikana tutkittavilta mitattiin samanaikaisesti lihasaktiivisuuksia, sykett\u00e4 ja hapenkulutusta. Aluksi mitattiin lepolaktaatti ja juoksukuormien sek\u00e4 viimeisen kuorman lopuksi mitattiin laktaattikonsentraatiot sormenp\u00e4\u00e4 verin\u00e4yttein\u00e4. Kaikille tuloksille laskettiin keskiarvot tasaisinta nopeutta vastanneelta 80 metrin suoralta jokaisella etenemisnopeudella. Tutkimustuloksina saatiin, ett\u00e4 aktiivisuus takareidess\u00e4 (kaikilla k\u00e4vely- ja yhdell\u00e4 juoksunopeudella) sek\u00e4 leve\u00e4ss\u00e4 kantalihaksessa (kaikilla k\u00e4vely- ja nelj\u00e4ll\u00e4 juoksunopeudella) erosivat ryhmien v\u00e4lill\u00e4 (0,001<p\u22640,05). N\u00e4iss\u00e4 lihaksissa juoksua harrastavien aktiivisuudet olivat pienempi\u00e4. Saatu tulos voi viitata harrastavien parempaan liiketekniikkaan. Muilla lihaksilla ei tilastollisesti merkitsevi\u00e4 eroja havaittu ryhmien v\u00e4lill\u00e4. Lihasaktiivisuus kasvoi nopeuden kasvaessa (0,001<p\u22640,05), mik\u00e4 on linjas-sa aikaisempien tutkimustulosten kanssa. Ryhmien v\u00e4lill\u00e4 ei l\u00f6ydetty tilastollisesti merkitsevi\u00e4 eroja lihasaktiivisuuksille ja hapenkulutuksille lasketuissa korrelaatioissa. Kaikilla tutkittavilla analysoitaessa etureidell\u00e4 (r=0,883) sek\u00e4 etummaisella s\u00e4\u00e4rilihaksella (r=0,914) havaittiin yhteys lihasaktivaation ja hapenkulutuksen v\u00e4lill\u00e4 (0,01<p\u22640,05) k\u00e4velynopeuksilla. Juoksunopeuksilla takareidell\u00e4 (r=0,789) ja pakaralla (r=0,788) havaittiin yhteys lihasaktivaation ja hapenkulutuksen v\u00e4lill\u00e4 (p\u22640,05). Hapenkulutuksissa tilastollisesti merkitsev\u00e4t ryhmien v\u00e4liset erot syntyiv\u00e4t viimeisell\u00e4 k\u00e4vely- sek\u00e4 ensimm\u00e4isell\u00e4 juoksunopeudella (p\u22640,05). Harrastavien hapenkulutukset olivat keskim\u00e4\u00e4rin alhaisempia tutki-tuilla nopeuksilla pois lukien ensimm\u00e4inen k\u00e4velynopeus sek\u00e4 kaksi viimeisint\u00e4 juoksunopeutta. Kah-della viimeisell\u00e4 juoksunopeudella harrastavien hapenkulutus oli suurempaa kuin harrastamattomilla. Juoksunopeuksien muutosta selitt\u00e4nee juoksua harrastamattomien kuormituksen muuttuminen enemm\u00e4n anaerobiseksi, joka n\u00e4kyy t\u00e4m\u00e4n ryhm\u00e4n laktaattikonsentraatioiden nousuna juoksu kuormien aikana sek\u00e4 hapenkulutuksien tasaantumisena kahden viimeisen juoksukuorman kohdalla. Sykkeet ja mitatut juoksukuormien laktaattikonsentraatiot olivat alhaisempia juoksua harrastavilla verrattuna harrastamattomiin ja ne erosivat ryhmien v\u00e4lill\u00e4 (0,001<p\u22640,01).", "language": "fi", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.abstract", "value": "The results of the study showed that activity in the hamstrings (at all walking and one running speed) and in the soleus (at all walking and four running speeds) differed between the groups (0,001<p\u22640,05). With these muscles, recreational runners had lower levels of muscle activity. The result might indicate that recreational runners might have had better movement technique. For the other muscles, no statisti-cally significant differences were found between the groups. Muscle activity increased with increasing speed (0,001<p\u22640,05) which is in line with previous studies. No statistically significant differences were found between the groups in the correlations calculated between muscle activities and oxygen consumptions. When all subjects were analyzed, with quadriceps femoris (r=0,883) and tibialis muscle (r=0,914) a relation was found between muscle activity and oxygen consumption (0,01<p\u22640,05) at walking speeds. At running speed, with hamstring (r=0,789) and qluteus muscle (r=0,788) a relation was found between muscle activity and oxygen consumption (p\u22640,05). Statistically significant differ-ences in oxygen consumption occurred at the last walking and at the first running speed between groups (p\u22640,05). Oxygen consumption by recreational runners was on average lower at all studied speeds, except for the first walking and last two running speeds. With the last two running speeds ox-ygen consumption was higher for runners than for non-runners. The change with two last running speeds is likely to be explained by the change of the load to be more anaerobic for the non-runners, which is reflected in an increase in lactate concentrations with running loads and oxygen consumption stabilization in the non-runners group within two last running speeds. Heart rates and measured lactate concentrations after running loads were lower in recreational runners group compared to non-runners group and results differed between the groups (0,001<p\u22640,01).", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2020-04-09T05:39:29Z\r\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2020-04-09T05:39:29Z (GMT).
