Koj puas tau xav tias koj tsaug zog hmo ntuj li cas? Cov cuab yeej zoo li FitBit taug kev tsaug zog los ntawm kev tshuaj xyuas koj lub zog nyob rau hmo ntuj, tab sis lawv tsis tuaj yeem saib seb koj lub paj hlwb ua dab tsi.

Tom qab ib semester ntawm kev kawm paub txog kev ntsuas kev kho mob, peb chav kawm tau sib tw nrog txoj haujlwm ntawm kev tsim cov cuab yeej siv tau los ntsuas qee qhov kev hloov pauv hauv lub cev. Kuv tus khub thiab kuv tau xaiv los tsim lub taub hau uas tuaj yeem saib seb koj lub paj hlwb ua dab tsi thaum tsaug zog. Lub taub hau nyeem ntawv lub suab nthwv dej lub suab kom saib xyuas kev pw tsaug zog. Nws txheeb xyuas yuav ua li cas tus neeg siv lub paj hlwb tsis nce qib los ntawm alpha, beta, gamma, thiab delta theem thaum hmo ntuj. Cov ntaub ntawv tuaj yeem raug xa tawm thiab tshuaj xyuas hauv Excel.

Peb puas tau hais txog nws qhov zoo nkauj ib yam?

Kauj Ruam 1: Cov Khoom & Cov Cuab Yeej

Txhawm rau tsim Lub Hau Kev Nyeem Ntawv Lub Hau, koj yuav xav tau cov ntaub ntawv hauv qab no:
