Postresistance Exercise Ethanol Ingestion and Acute Testosterone Bioavailability

Abstract

Postexercise ethanol ingestion affects the hormonal milieu including testosterone concentration and bioavailability during recovery from resistance exercise.

Alcohol consumption and hormonal alterations related to muscle hypertrophy: a review

“…Hormonal levels of testosterone have also been measured after heavy resistance exercise [85]. Participants consumed either 1.09 g/kg of grain ethanol per kilogram lean mass (EtOH group) or no ethanol post exercise (placebo group).…”

“…At 140–300 min post exercise, total testosterone and free testosterone levels as well as free androgen index were significantly higher only in the EtOH group. The study demonstrated that during the recovery period from heavy resistance exercise, post exercise ethanol ingestion affects the hormonal profile including testosterone concentrations and bioavailability [85]. …”

The Effects of Alcohol Consumption on Recovery Following Resistance Exercise: A Systematic Review

“…Of the retrieved studies, 10 took into account at least one biological measure [9,[18][19][20][21][22][23][24][25][26], 11 took into account at least one physical measure [9,[18][19][20][21][22][23][24][25]27,28] and cognitive function only one [24].…”

“…The retrieved biological measures include creatine kinase (CK) [18][19][20][21][22][23][24][25], heart rate [19,26], lactate [19,26], blood glucose [9], urine measures [24], cortisol [19,21,24,26], testosterone [19,21,24,26], estradiol [26], sexual hormone binding globulin (SHBG) [21,26], leukocytes and cytokines [19,21,22], C-reactive protein (CRP) [24], plasma amino acids [9], intracellular signaling proteins and rates of muscle protein synthesis (MPS) [9] and calcium (Ca 2+ ) [25]. The physical measures include force [18,[20][21][22][23][24][25]27,28], power [19,21,24,28], muscular endurance [25], soreness [18,…”

“…The maximum score a study can receive is 32, with higher scores indicating better quality. The studies were then divided into groups and marked as 'high quality' (score [23][24][25][26][27][28][29][30][31][32], 'moderate quality' (score [19][20][21][22], 'lower quality' (score [16][17][18] or 'poor quality' (<14) (Supplementary File S1 and S2). Kendall Tau correlation coefficient statistical method was used to determine inter-rater reliability.…”
