Otsіnka pristosuvannya Sertsevy-sudinnoї system before the Labour navantazhen

Stan Sertsevy-sudinnoї Sistemi pratsіvnika deposits od navantazhen of labor. For otsіnki її adaptovanostі to Tsikh navantazhen porіvnyuyut pokazniki sistolіchnogo krov'yanogo vises i heart rate pid hour i Robot in stanі Spock.

Koefіtsієnt pіdvischennya sistolіchnogo (maximum) vise rozrahovuєtsya of the formula:

de Rs.rob - sistolіchny vise during robotі mm Hg. Article .; Rs.sp - sistolіchny clutches of stanі Spock mm Hg. Art.

Koefіtsієnt pіdvischennya heart rate rozrahovuєtsya of the formula:

de nrob - frequency pulse pid hour robots; nsp - heart rate stanі Spock.

Yakscho K1> K2, the regulyatsіya Sertsevy-sudinnoї dіyalnostі vіdbuvaєtsya normal; Yakscho K1 <K2, the Got Location Sertsevy nedostatnіst.

About rіven trenovanostі Sertsevy-sudinnoї Sistemi pratsіvnika to fіzichnih navantazhen svіdchit koefіtsієnt vitrivalostі

Zbіlshennya koefіtsієnta vitrivalostі in zv'yazku Zi zmenshennyam pulse Je vise pokaznikom detrenovanostі Sertsevy-sudinnoї Sistemi pratsіvnika. Another pokaznikom, yaky harakterizuє pristosuvannya Sertsevy-sudinnoї system before fіzichnih navantazhen, Je pokaznik of Quality reaktsії. Vіn konkretnіshe harakterizuє vіdnovlennya krov'yanogo vises i heart rate pіslya vikonannya іntensivnoї works:

de Kp - pokaznik reaktsії of Quality; Pn1 i Pn2 - TISK pulse before i pіslya robots; i n1 n2 - frequency pulse until i pіslya robots.

In normі Kp <1 Zbіlshennya tsogo pokaznika svіdchit about nespriyatlivu reaktsіyu Sertsevy-sudinnoї Sistemi at Helsinki Human navantazhennya.
