Kunyangwe izvi zvingaite senge zvine musoro, ndinokahadzika kuti vanhu vazhinji vanoziva chikonzero chaicho nei zvichidikanwa kuti titarise kunonoka kwetsandanyama chibvumirano kana uchiita seti dzekudzokorora. Kana kuti pamwe waigara uchinetseka kuti sei uye nhasi tiri kuzokuratidza mhinduro.
Tsandanyama dzedu dzinoita chibvumirano nekuda kwekuwanda kwakasiyana kwebiological uye kemikari kuita, zvese izvi zvinoitika mukati memamirisecond akati wandei. Izvi zvinobvumira kuyambuka-mabhiriji kuumba actin uye myosin (mhando mbiri dzeprotein) dzinowedzera kana tsandanyama dzichibatana. Iyo yakaderera huwandu hwehuremu hwatinofamba mukudzidziswa (pasina kusvika kune kukundikana), iyo inokurumidza chiyero chechibvumirano, ichibvumira nhamba shoma ye actin-myosin-cross-bridges kuti iumbe. .
Myofibrillar vs sarcoplasmic hypertrophy: chii chimwe nechimwe?
Sezvo kutaura kwedu kwesimba kwakanyatso kuenzana nehuwandu hwemabhiriji akaumbwa, kuve neactin-myosin mhiri-mabhiriji mashoma akaumbwa zvinoreva kuti simba shoma rinogadzirwa.
Kune rumwe rutivi, kurema kwemutoro, kunonoka kwehuwandu hwekugadzirisa, zvichibvumira mamwe actin-myosin-cross-bridges kuti aumbe. Zvekare, simba rekubuditsa rinoenderana zvakananga nehuwandu hwemabhiriji akaumbwa, izvi zvinoreva kuti kugadzirwa kwesimba kuchavawo kukuru. .
Ngatitarisei pane simba-velocity musimboti
Sezvo kukurumidza kwekupfupisa kwemisungo yemhasuru (fast twitch) inowedzera, simba rinogadzirwa rinoderera (uye zvinopesana). Tsandanyama faibha dzinoshandisa masimba makuru kana dzakapfupikiswa zvishoma nezvishoma, asi masimba mashoma kana apfupikiswa nekukurumidza. Izvi zvinodaro mwero unononoka wekupfupisa unobvumira akawanda actin-myosin mhiri-mabhiriji kuti aumbe panguva imwe chete, uye actin-myosin mhiri-mabhiriji ndiwo anobvumira imwe neimwe tsandanyama fiber kuburitsa simba.
Sezvineiwo, mitengo yekukurumidza yekupfupisa inokonzeresa kuti actin-myosin muchinjika-mabhiriji mukati memhasuru fibers iputsike nekukurumidza, zvichitungamira kune mashoma panguva imwe chete mabhiriji kuumba chero nguva. Saka kana iwe uchida kuwedzera simba rako, zvakakosha kuti uise pfungwa pakuita inononoka tsandanyama contraction.
