Abstract The purpose of this investigation was to examine the acute responses of several hormones [total and free testosterone (TT and FT, respectively), adrenocorticotropic hormone (ACTH), cortisol (C), growth hormone (GH), and insulin (INS)] to a single bout of heavy resistance exercise (HRE). Eight younger [30-year (30y) group] and nine older [62-year (62y) group] men matched for general physical characteristics and activity levels performed four sets of ten repetitions maximum (RM) squats…

Comparison of Acute Hormonal Responses between Resistance, Endurance and Endurance-Resistance Exercise in Healthy Young Men
TLDR
The E and ER protocols can increase GH with lower lactate and cortisol production, while the R protocol provides better anabolic environment for development and hypertrophy of muscle fiber because of higher stress, metabolic and hormonal responses.
Anabolic and catabolic hormonal responses to experimental two-set low-volume resistance exercise in sedentary and active elderly people
TLDR
The data indicate that low-volume resistance exercise may decrease cortisol levels and increase serum anabolic/catabolic hormone ratios, and should be corroborated by long-term low- volume resistance training programs.
Hormonal responses from concentric and eccentric muscle contractions.
TLDR
Con exercise increases GH concentrations to a much greater extent than ECC exercise at the same absolute load, and it is likely that greater GH responses were related to intensity rather than mode of contraction.
Acute hormone responses to heavy resistance lower and upper extremity exercise in young versus old men
TLDR
The present data would indicate that the responses of GH, TT and FT to heavy resistance isometric exercise are lowered with increasing age, which may indicate decreased anabolic effects on muscles and may explain in part the loss of muscle mass and strength associated with aging.
Androgen receptor content following heavy resistance exercise in men
The Effect of Post-exercise Ethanol Consumption on the Acute Hormonal Response to Heavy Resistance Exercise in Women
TLDR
An acute modulation of the neuroendocrine milieu following a heavy resistance exercise bout in women was demonstrated and Ethanol ingestion appeared to have no significant effect on the characteristics of acute hormonal augmentation in TT, FT, GH, COR, IGF-1, or E2.
Associations of exercise-induced hormone profiles and gains in strength and hypertrophy in a large cohort after weight training
TLDR
It is reported that the acute exercise-induced systemic hormonal responses of cortisol and GH are weakly correlated with resistance training-induced changes in fibre CSA and LBM (cortisol only), but not with changes in strength.
Active and passive recovery influence responses of luteinizing hormone and testosterone to a fatiguing strength loading
TLDR
From a hormonal perspective, the present AR method appears to have had some favorable effects following the strenuous strength loading; however, acute decreases in muscular force production did not significantly differ between groups.
ACUTE HORMONAL RESPONSES TO SUBMAXIMAL AND MAXIMAL HEAVY RESISTANCE AND EXPLOSIVE EXERCISES IN MEN AND WOMEN
TLDR
The acute exercise-induced response during HRE may play an important role in the long-term anabolic adaptation processes related to muscle hypertrophy and maximal strength development.
The Acute Hormonal Response to Free Weight and Machine Weight Resistance Exercise
TLDR
Free weight exercises seem to induce greater hormonal responses to resistance exercise than machine weight exercises using similar lower-body multijoint movements and primary movers.

Hormonal and growth factor responses to heavy resistance exercise protocols.
TLDR
The data indicate that the release patterns observed are complex functions of the type of HREPs utilized and the physiological mechanisms involved with determining peripheral circulatory concentrations (e.g., clearance rates, transport, receptor binding).
Endogenous anabolic hormonal and growth factor responses to heavy resistance exercise in males and females.
TLDR
Growth hormone increases in both males and females following the P-2 HREP were significantly greater at all time points than corresponding P-1 values; Females exhibited significantly higher pre-exercise hGH levels compared to males.

TLDR
The effects of long-term resistance training on circulating levels of GH and insulin-like growth factor I (IGF-I) and on the acute GH response to exercise in 5 men and 9 women, aged 69.6 +/- 1.1 yrs (SEM) are studied.
Acute hormonal responses to heavy resistance exercise in men and women at different ages.
TLDR
The primary results indicate that the response of GH concentrations to the same relative heavy resistance work load is greatly lowered with increasing age both in men and women, while acute responses in testosterone levels are minor.
Effect of acid-base balance on the growth hormone response to acute high-intensity cycle exercise.
TLDR
Data indicate that an increase in blood hydrogen ion concentration may be partly responsible for the hGH response to acute high-intensity anaerobic exercise.
Hormone and metabolite response to weight-lifting training sessions.
TLDR
Weight lifting induced changes in blood metabolites which reflect a mobilization of both carbohydrates and lipids stores for energy, which are smaller than the ones reported for endurance or interval running, which use larger muscle groups.
Training responses of plasma beta-endorphin, adrenocorticotropin, and cortisol.
TLDR
While exercise-induced increases were observed, the C group exhibited significant post-training reductions in plasma responses of beta-EP, ACTH, and blood lactate concentrations in response to maximal exercise.

Muscle strength and serum testosterone, cortisol and SHBG concentrations in middle-aged and elderly men and women.
TLDR
Examination of muscle cross-sectional area and maximal voluntary isometric force production characteristics of the leg extensor muscles and serum androgen and sex hormone binding globulin (SHBG) concentrations found both middle-aged and elderly groups demonstrated greater values than the respective elderly groups of the same sex.
