My 10 commandments regarding lifting weights and hairloss

[docj077]

Yes lifting weights can raise testosterone levels (if you are working out correctly and eating right), but the raise is not very signifigant. It is not a "night and day" difference...it is more like a "night and an hour later that night".

The slight boost you get should not translate into any real hair loss, if it does you were predisposed to lose it anyways and probably just happened a tad sooner.

Genetics are either a blessing or a b**ch huh.

As for the rest of the stuff (like creatine causing hair loss) is simply ludicris.

-A single bout of short and intensive aerobic and anaerobic exercise usually increases serum testosterone level.
-Prolonged moderate to intense exercise (> 2 hours) leads to an initial increase followed by a decline to or below the baseline levels.
-Exercise training frequently results in a decrease of serum testosterone, and may rarely be associated with reduced libido, sperm production and fertility.
-In addition, the reduced testosterone levels may attenuate the exercise-associated muscle hypertrophy, reduce the repair of muscle damage, reduce post exercise muscle rehabilitation and may play an important role in the development of over-training syndrome.
-Other consequences include decreased bone density and a possible effect on mood and behavior.

The evidence available, however, suggests that a slowly developing process requiring years of exercise training results in these changes.

-Potentially, the lowered testosterone levels of the endurance-trained male could disrupt some of their anabolic or androgenic dependent processes.
-To date, there are only a limited number of findings suggesting that a consistent disruption of testosterone dependent processes occur due to endurance exercise training (e.g., oligo-spermatogenesis).
-Conversely, the alterations in testosterone concentration brought about by endurance training could have cardiovascular protective effects and thus be beneficial to the health of men.

I'm sure there are some gentlemen interested in this study.

Dietary Intake, Serum Hormones, Muscle Mass and Strength During Strength Training in 49 - 73-Year-Old Men.Sallinen J, Pakarinen A, Fogelholm M, Alen M, Volek JS, Kraemer WJ, Häkkinen K.
Department of Biology of Physical Activity and Neuromuscular Research Center, University of Jyväskylä, Jyväskylä, Finland.

Effects of dietary intake on serum hormones, muscle cross-sectional area (CSA) and strength during strength training were studied in two groups of men: 1) strength training + nutritional counseling (n = 22, 59.1 +/- 6.1 yrs), and 2) strength training (n = 23, 58.5 +/- 7.1 yrs). Both groups performed strength training twice a week for 21 weeks. Counseling increased carbohydrate (p < 0.01) and fiber intake (p < 0.001) and polyunsaturated/saturated fat-ratio (p < 0.05) and decreased fat intake (p < 0.01). Muscle strength and CSA increased by 16 - 20 % and by 5.4 - 5.9 % in both groups (p < 0.001). Changes in protein content of diet correlated with the changes in the acute postexercise concentrations of total (r = 0.64, p < 0.01) and free testosterone (r = 0.54, p < 0.05) after training in the counseling group. Moreover, changes in the free testosterone responses to heavy-resistance exercise correlated with the increases in the muscle CSA (r = 0.52, p < 0.05) in the counseling group. Serum basal testosterone/sex hormone-binding globulin-ratios correlated with the body mass normalized energy (kJ/kg: r = 0.54, p < 0.001), protein (g/kg: r = 0.42, p < 0.01) and fat (g/kg: r = 0.51, p < 0.01) intake in all participants during the training. The data indicate that protein and fat intake may influence serum testosterone concentrations and that the changes in exercise-induced testosterone responses may contribute to muscle mass development during strength training.

IMHO if you are on DHT blockers (propecia, dutas) exercise and DHEA supplements will become in more free testosterone, but not in more DHT. So your hair is not in danger.
