Inadequate water intake and subsequent hypo-hydration degrades central nervous system performance and significantly decreases exercise performance during multiple sets of back squats.

Are you thinking hydration?

A survey of almost two-thousand adult male, non-medical anabolic steroid (AAS) users in the United States found the typical user to be approximately 30 years old, highly-educated and Caucasian, with an above average income and no active involvement in organized sports. Researchers observed the focus on elite-level athletes and tragedies among adolescents has led to ineffective policy, given it missed the vast bulk of educated AAS users who were responsible in their use.

A bronze tribute immortalizing the typical steroid user.

A study examining the effects of progressive resistance training on men receiving androgen deprivation therapy (a treatment for prostate cancer) found muscle strength, endurance, and thickness all increased significantly after training.

Penile Vaginal Intercourse (a.k.a. PVI), (not anal sex, not oral sex, and not masturbation) is the only sexual behavior associated with indicies of better physical and mental health in a growing body of empirical literature. It just so happens PVI is also the one behavior responsible for gene propagation, (which seems to make sense on an intuitive level). African Bat Bugs have penises that look and act like hypodermic needles. Males don't bother to use their female counterparts vaginas, instead using their hypodermic-needle-like penises to pierce the females' abdomen and ejaculate directly into the bloodstream, where sperm then swim to the ovaries.

Not exactly well-hung; more like a needle dick, actually.

While levels of circulating Testosterone, Growth Hormone (GH) and IGF-1 are lower in healthy aging men, researchers at the NIH found supplementing low-dose Testosterone for 26 weeks increased nocturnal GH secretion and morning serum IGF-1 concentrations. Racing across long distances of frozen Alaska has a suppressive effect on the hypothalamic-pituitary gonadal axis in men. Researchers concluded this was likely due to the amplification of adrenal stress responses to an ultra-endurance race in environmentally stressful conditions.

Frozen nuts and suppressed HPTA.

Greek researchers studing the effects of exercise on hormone levels in 11-13 year old males found significant differences in bodyfat, Testosterone, and Free Androgen Index (FAI). Testosterone levels were 300 percent higher, and FAI was 600 percent higher in the weight-training group compared to the aerobic group.

Scientists studying effects of exercise on mood, dividing nursing home residents into three groups: walking, comprehensive exercise, and social conversation. They found residents receiving comprehensive exercise showed the highest positive and lowest negative affect and mood post study. Those who engaged exclusively in social jaw flapping exhibited the least positive and most negative results.

A little iron beats a lot of talk.

Lower body muscle strength is independently associated with insulin resistance, and resistance training improves glycemic control in subjects with type 2 diabetes. Following a night of only four hours sleep, a 30-minute post-lunch nap improves alertness and aspects of mental and physical performance.

Take a lesson from man's best friend.

Enhancing the quality of sleep improves quality of life. A broad range of sleep related disorders associated with abnormal sexual behaviors and experiences exist. According to scientists, having sex with friends tends to complicate friendships.

The relationship equation: Copulate = Complicate.

Women experience higher levels of Testosterone prior to having intercourse, and data points to associations between Testosterone and orgasm, sexual desire, and relationship commitment.

If her Testosterone levels were any higher, those panties would hit the pavement.

Women also experience fluctuations in cognitive ability during their menstrual cycle. Between one and 9.7 percent of men experience ejaculatory pain. This could occur due to prostatitis, ejaculatory duct obstruction, prostatic hyperplasia, or a reverse donkey punch.

When hurts so good hurts so bad.

Supplementing with protein resulted in significant lean mass gains. Even twelve weeks of soy protein supplementation did not inhibit lean mass gains or decrease serum Testosterone levels in the resistance trained.

Researchers found Creatine Monohydrate (CrM) plus conjugated linoleic acid (CLA) enhanced the beneficial effects of training. Old people (aged 65+) treated to a six-month course of resistance training with CrM plus CLA experienced greater increases in muscular strength and endurance, lean mass, and lowered fat mass than those who followed the same routine minus the supplements. Potential benefits on sprint performance from increased strength due to resistance training may not occur immediately and are likely to be affected by mechanical specificity.

People who performed ten weeks of stretching experienced significant improvements in flexibility, vertical and standing long jump performance, 20m sprint, knee flexion and knee extension endurance. This was in the absence of exercise, and a control group saw no improvements.

Maybe this flexibility stuff has its uses.

Training one arm for strength increases the strength of the untrained arm as well as the trained arm, thanks in part to adaptations within the sensorimotor cortex. Subjects who simply imagined strength training one arm showed no increase in strength in either arm.

Well, at least in most people.

Evidence of female ejaculation and the existence of the G-spot is being challenged and the debate is ongoing among some scientists. And some people believe man never landed on the moon.
