Blood hormones were sampled pre- and post-intervention from an antecubital forearm vein and analysed using electrochemiluminescent immunoassay. Cardiorespiratory fitness ([Formula: see text]) was determined via indirect calorimetry during an incremental cycle test to volitional exhaustion. RESULTS: Analysis of variance (ANOVA) revealed a lack of significant change in any parameter amongst LE, whilst SED experienced a significant exercise-induced improvement in cardiorespiratory fitness and total testosterone (all p < 0.05). Concurrent increases in sex hormone-binding globulin (SHBG; p < 0.05) resulted in a lack of change to either bioavailable or calculated free testosterone (p > 0.05) amongst SED. CONCLUSIONS: Although resting levels of systemic total testosterone increased in response to 6 weeks of exercise training, increases in SHBG negated any potential relationship between calculated-free or bioavailable testosterone. These findings indicate that increases in bioavailable testosterone fraction are not required for cardiorespiratory fitness improvements in aging men.]]> Wed 07 Apr 2021 13:56:59 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11709 Wed 07 Apr 2021 13:56:59 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11708 0.05). CONCLUSIONS: Findings from this investigation suggested that resting levels of serum T and calculated free-T was unable to distinguish between diverse lifelong training histories in aging men. Further, sal-T was not an appropriate indicator of serum T and calculated free-T values in older males and considerable caution should be exercised when interpreting sal-T measurements in aging males.]]> Wed 07 Apr 2021 13:56:59 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11706 Wed 07 Apr 2021 13:56:59 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11705 Wed 07 Apr 2021 13:56:59 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11704 Wed 07 Apr 2021 13:56:59 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11703 Wed 07 Apr 2021 13:56:59 AEST ]]>
