Figure 1

Hypothesized moderation model of potential effects of sex (moderator) on the relationship between HIIT and CRF through MSF (mediator). Numbers indicate effects of moderation on mediation model’s elements: (1) indirect influence of HIIT on CRF, (2) component: HIIT effect on MSF (MSFI, HG, ABS, FL, VJ), and (3) component: MSF (MSFI, HG, ABS, FL, VJ) effect on CRF.
