Baidarininkų aerobinio pajėgumo ugdymas

Abstract

Baidarininkams įveikiant 1000 m nuotolį aerobinio energijos gamybos būdo įnašas siekia 70-80 %, todėl daug baidarininkų rengimo laiko turi būti skiriama aerobinio pajėgumo ugdymui. Darbo tikslas – išnagrinėti didelio meistriškumo baidarininkų, dalyvaujančių 1000 m nuotolio rungtyje, aerobinio ugdymo vyksmą parengiamuoju laikotarpiu. Tirtas Lietuvos čempionų, pasaulio vicečempionų parengiamuoju laikotarpiu atlikto fizinio krūvio priemonių ir metodų turinys. Aerobinio pajėgumo kaita tirta su dujų analizatoriumi „Oxycon Mobile781023-052-5.2“ krūvį atliekant baidarių irklavimo ergometru „Dansprint“. Lapkričio mėnesio treniruotės mezociklą sudarė penki mikrociklai: 1) įvadinis – penkerios pratybos; 2) didėjančio fizinio krūvio – penkerios pratybos; 3) dalinio atsigavimo – ketverios pratybos; 4) didelio fizinio krūvio – septynerios pratybos; 5) atsigavimo ir superkompensacijos – ketverios pratybos. Gruodžio mėnesio treniruotės mezociklas išsiskyrė tuo, kad vienas mikrociklas buvo skirtas deguonies suvartojimo didinimui taikant specialius fizinius krūvius. Vasario mėnesio mezociklo būdingi bruožai: pratybų skaičius mikrocikluose padidėjo iki 8, buvo taikomi pratimai, ugdantys kreatinfosfatinį galingumą, ir pradėti taikyti fiziniai krūviai, skatinantys glikolitines reakcijas, penktas mikrociklas buvo skirtas atsigavimui ir superkompensacijai, jo metu buvo atlikti etapiniai tyrimai. Į kiekvieno baidarininkų treniruotės mezociklo struktūrą buvo įtraukti įvadiniai ir atsigavimo bei superkompensacijos mikrociklai. Mikrocikluose dvi arba trys dienos buvo skirtos atsigavimui. Tiriant nustatyta, kad per tris mėnesius baidarininko R. N. parengtumas smarkiai pagerėjo: VO2 max padidėjo nuo 56,1 iki 67,5 ml/min/kg, darbo galia išaugo nuo 280 iki 320 W. Tyrimo rezultatai parodė, kad baidarininkų atlikti fiziniai krūviai, jų derinimas su atsigavimo ir superkompensacijos laiko tarpsniais buvo veiksmingi ugdant jų aerobinį pajėgumą.

In 1000 m kayak rowing event aerobic energy production amounts from 70 to 80 percent. Due to this fact, training of kayak rowers must include significant amounts of aerobic capacity development. The aim of the research was to investigate aerobic capacity development process during the preparatory period of elite kayak rowers participating in 1000 m event. We performed the study on the content of means and methods of the non-water training load, carried out by Lithuanian champions, World Championship silver medal winners at the beginning of their preparatory period. Change of aerobic capacity was studied using gas analyzer “Oxycon Mobile 781023-052- 5.2”, the training load being performed using kayak rowing ergometer “Dansprint”. November training mezocycle included 5 microcycles: introductory – 5 sessions; increasing training load – 5 sessions; partial recovery – 4 sessions; great training load – 7 sessions; recovery and supercompensation – 4 sessions. Characteristic feature of December training mezo-cycle was a microcycle, devoted to VO2 max increase applying special training load. Characteristic features of February mezocycle were the following: increased number of training sessions up to 8 within microcycles, exercises for creatine phosphate capacity development were included, and application of training load for glycolytic reactions stimulation were initiated. The fifth microcycle was devoted to recovery and supercompensation and included on-stage testings. Within the structure of kayak rowers’ each training mezocycle, characteristic was involvement of introductory and recovery supercompensation microcycles. The carried out investigation demonstrated remarkable progress of kayak rower R.N. during a three months period: VO2 max increased from 56,1 to 67,5 ml/min/kg, working capacity increased from 280 W to 320 W. The study proved effectiveness of kayak rowers’ performed training load, its adjustment to recovery and supercompensation periods in development of kayak rowers’ aerobic capacity.
