M. iliopsoakselle tehokkain harjoite oli jalan taaksevienti alataljassa, jossa tukijalan puoli tuotti suuremman lihasaktiivisuuden (26. 7\u00b1 16.7 %MVIC). Maastaveto oli tehokkain harjoite niin m. lumbar erector spinaelle (47.7\u00b1 24.6 %MVIC) kuin m. multifidukselle (35.6\u00b1 16.5 %MVIC). Kaikkien lihasten aktiivisuustasojen keskiarvojen mukaan maastaveto oli tehokkain harjoite (19.6 \u00b1 12.3 %MVIC).\nTutkimuksen tulokset ovat samansuuntaisia aikaisempien tutkimusten kanssa, joissa on raportoitu maastavedon ja vaakapenkin olevan tehokkain harjoite selk\u00e4lihaksille.

In the last 30 days 48% of women and 44% of men had experienced low back pain according to the FinTerveys 2017 study done by the Finnish Institute for Health and Welfare. In treating low back pain, therapeutic exercise has been found to have an impact on physical performance and alleviating the symptoms. Especially progressive strength and functional training has been found to be an effective way to treat low back pain. \nThe purpose of this study was to determine and compare the activity levels of the core musculature during the exercises. The participants were voluntary, physically active (n=9) healthy adult males, aged 28 years on average. Muscle activity was measured by surface electromyography from six core muscles during ten different exercises, and it is presented as electrical muscle activity in relation to maximal voluntary isometric contraction (%MVIC). The values presented are means and standard deviations (SD). \nAccording to the statistical analyses, the differences between the activity levels of the exercises were shown to be statistically significant (p<0.001). The highest average EMG-value from all of the trunk muscles combined was observed during deadlift (19.6\u00b1 12.3 %MVIC). For m. rectus abdominis, the most efficient exercise was rotational plank (11.9\u00b1 4.7 %MVIC) as well as for m. external oblique (20.8\u00b1 9.3 %MVIC). M. internal oblique produced the highest average muscle activity in cable push and pull, in which the side that was pulling produced higher muscle activity (16.7\u00b1 6.9 %MVIC). For m. iliopsoas, the highest muscle activity was during the cable hip extension on the grounded supporting leg (26.7\u00b1 16.7 %MVIC). Deadlift was the most efficient exercise for m. lumbar erector spinae (47.7\u00b1 24.6 %MVIC) and m. multifidus (35.6\u00b1 16.5 %MVIC). \nThese results are in alignment with previous studies, where deadlift and lumbar extension bench were reported to produce the highest levels of muscle activity in the lumbar muscles. For abdominal muscles, different plank variations, especially side plank, has been reported to produce significantly higher muscle activation compared to other exercises. The results of this study might be used in progressive rehabilitation programs for treating low back pain, depending on the individual needs of the patient.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2021-07-14T04:57:51Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2021-07-14T04:57:51Z (GMT).
