Toistaiseksi on olemassa v\u00e4h\u00e4n tutkittua tietoa plyometrisen nopeusvoimaharjoittelun vaikutuksista lihasj\u00e4nnekompleksin toimintaan ja rakenteeseen. Tutkimuksen tarkoituksena oli m\u00e4\u00e4ritt\u00e4\u00e4 plyometrisen ja konsentrisen nopeusvoimaharjoittelun vaikutuksia lihasj\u00e4nnekompleksin toimintaan ja rakenteeseen 12 viikon harjoittelun aikana. Tutkimukseen osallistui 12 20-30 \u2013vuotiasta tervett\u00e4 miest\u00e4, jotka jaettiin kahteen ryhm\u00e4\u00e4n (konsentrinen; CON ja plyometrinen; SSC). CON ryhm\u00e4 suoritti harjoittelun paineilmalaitteilla ja SSC ryhm\u00e4 hyppyharjoitteluna kelkkaergometriss\u00e4. Molemmat ryhm\u00e4t harjoittelivat nopeusvoimaperiaatteella 2-3 kertaa viikossa. SSC-ryhm\u00e4 harjoitteli kelkkaergometrill\u00e4 ja CON- ryhm\u00e4 harjoitteli paineilmalaitteella. Rakenteellisissa muutoksissa tarkasteltiin akillesj\u00e4nteen venymist\u00e4 sek\u00e4 lyhenemist\u00e4 pudotushyppyjen aikana, akillesj\u00e4nteen poikkipinta-alaa kolmesta kohtaa (1cm, 2cm ja 3cm kantaluusta yl\u00f6sp\u00e4in), akillesj\u00e4nteen pituutta seisoessa sek\u00e4 soleuksen, lateralis ja medialis gastrocnemiuksen poikkipinta-alaa. Muutokset m\u00e4\u00e4riteltiin ultra\u00e4\u00e4nen avulla. Toiminnallisissa muutoksissa tarkasteltiin hyppykorkeutta, pudotuskorkeutta, voimantuottoa, kontaktiaikaa sek\u00e4 lihasaktiivisuutta soleus, medialis gastrocnemius ja tibialis anterior \u2013lihaksista. Molemmilla ryhmill\u00e4 erityisesti voimantuottoaika pieneni. Tibialis anterior/soleus koaktivaatio pieneni SSC-ryhm\u00e4ll\u00e4 merkitsev\u00e4sti pudotettaessa maksimikorkeudesta alku- ja loppumittausten (4,06\u00b11,07, 1,60\u00b10,43(p<0,01)) v\u00e4lill\u00e4. Lihasten poikkipinta-alassa SSC-ryhm\u00e4ll\u00e4 medialis gastrocnemius (GM) ja soleus \u2013lihaksissa (SOL) tapahtui alku- ja loppumittausten (GM; 5,30\u00b11,39 cm\u00b2, 8,08\u00b11,89 cm\u00b2 (p<0,05); SOL 15,19\u00b11,63 cm\u00b2, 19,23\u00b11,30 cm\u00b2 (p<0,01)) v\u00e4liss\u00e4 tilastollisesti merkitsev\u00e4\u00e4 kasvua.
