Acute effects of bouts of BFR and HST on serum concentrations of sex hormone binding globulin and androstenedione in previously untrained women (n = 9), measured 1 min and 30 min after training sessions

Values are expressed as means ± SD. Each individual performed each of the two training protocols in a contralateral manner, with singular sessions of HST and BFR being performed both before (week 0; n = 7) and after (week 12; n = 9) 12 weeks of HST and BFR, in each case on different days, separated by 4–6 days.

s-SHBG, sex hormone binding globulin; s-AND, sex hormone binding androstenedione.

^*Signficant changes from baseline caused by BFR or HST (P < 0.05). No difference was found between HST and BFR.
