SummaryChanges in the testosterone concentrations after single sessions of endurance and strength training were measured in seven well trained men, experienced in both forms of training. Both training sessions were rated as hard to very hard on the Borg scale. Blood samples for testosterone measurements were taken before, immediately after, and 2, 4 and 6 h after the training sessions as well as the next morning. The mean tes tosterone concentration increased 27% (P<0.02) and 37% (P< 0.02… 

Figures and Tables from this paper

Effect of training status and exercise mode on endogenous steroid hormones in men.
TLDR
It appears that the endogenous hormone profile of men is more dependent on exercise mode or intensity than exercise volume as measured by caloric expenditure, and the relatively catabolic environment observed during the resistance session may indicate an intensity-rather than a mode-dependent response.
Effect of endurance exercise on resting testosterone levels in sedentary subjects.
TLDR
Twelve weeks of moderate-intensity and low frequency training had no effect on resting serum testosterone, but were sufficient to increase aerobic fitness among sedentary young men.
Effects of Strength Training on Submaximal and Maximal Endurance Performance Capacity in Middle‐Aged and Older Men
TLDR
The relationships found in this study between various indices of cycling testing and serum hormone concentrations after strength training suggest that maximal incremental cycling might be used as an additional test to detect anabolic-catabolic responses to prolonged strength training in middle-aged and older men.
Different hormonal response to continuous and intermittent exercise in middle‐distance and marathon runners
TLDR
A continuous running exercise results in a lower cortisol response in runners who are adapted for longer distances, and an intermittent running exercise resulted in a higher testosterone response in runner who is adapted to middle distances.
Maintenance of testosterone status in fitness joggers after increased training mileage
TLDR
It was concluded, that the training intervention did not alter T status in these fitness joggers.
Effect of acute DHEA administration on free testosterone in middle-aged and young men following high-intensity interval training
TLDR
Results demonstrate acute oral DHEA supplementation can elevate free testosterone levels in middle-aged men and prevent it from declining during HIIT, and D HEA supplementation may have significant benefits related to HIIT adaptation.
Effects of a 24-week same-session combined endurance and strength training program on physical performance and serum hormone levels in recreational endurance runners
TLDR
The present study confirmed that, training strength always after endurance may lead to an augmented stress to the endocrine system that ma y take several days to recover, and this training design may impede strength and power development, counteracting the benefits of strength training on endurance performance.
Salivary Testosterone and Cortisol Responses in Professional Rugby Players After Four Resistance Exercise Protocols
TLDR
RE induced significant individual, protocol-dependent hormonal changes lasting up to 30 minutes after exercise, which may have important ramifications for modulating adaptation to RE and could explain the variability often observed in studies of hormonal response to RE.

TLDR
A multivariate analysis of the data from the trained groups and sedentary, age-matched control groups showed that regular training has a significant effect on steroid excretion.

Serum testosterone concentration during two hours of moderate intensity treadmill running in trained men and women.
TLDR
Differences in the testosterone response between men and women during prolonged aerobic exercise are of interest and may imply that different mechanisms of control are involved.
Neuromuscular and hormonal responses in elite athletes to two successive strength training sessions in one day
TLDR
It is suggested that high intensity strengthening exercises may result in acute adaptive responses in both the neuromuscular and endocrine systems and Recording of muscle activation and muscle strength and analysis of certain serum hormone concentrations with sufficient frequency during the training process may be useful in optimizing and controlling the contents of individual training sessions and the full training program.
The effect of exercise on the production and clearance of testosterone in well trained young men
TLDR
It is suggested that the exercise-induced elevation of testosterone level is due solely to the reduction in the rate at which testosterone is cleared from the plasma, and that changes in the extrahepatic clearance of testosterone may also be involved.
Variations of serum testosterone concentrations after physical exercises of different duration.
TLDR
These findings, and similar variations of serum testosterone observed in an ultramarathon runner during a 6-h training session, suggest that serum testosterone increases during physical activities lasting up to 3 h and decreases to or even below the pre-exercise values for longer physical efforts.
Endurance Training and Testosterone Levels
TLDR
There are no findings to indicate that any consistent dysfunctions of any of the testosterone dependent processes in the male occur due to endurance training.
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.
A 7-week follow-up study of the behaviour of testosterone and cortisol during the competition period in rowers
TLDR
An increase in catabolic activity in periods of intensive physical strain, including competitions is suggested, and Regenerative phases of training seem to reduce the anabolic-catabolic imbalance.
The Effects of Exercise on Reproductive Function in Men
TLDR
The long term, physiological suppression of the hypothalamic-pituitary-gonadal axis in men is probably not of major significance but it is clear that further investigation in several areas is essential to provide continuing reassurance that ‘exercise is good for you’.
Serum testosterone, body composition, and strength of young adults.
TLDR
Correlations between serum testosterone, body composition, and static strength were nonsignificant in males and females and Comparisons of subjects with the highest and lowest levels of testosterone within each sex showed no significant differences in strength or body composition.
