Dnes jsem objevil docela zajímavou studii o vlivu ejakulace na hladinu testosteronu, často jsem o tom přemýšlel a konečně někoho napadlo udělat studii. Je to v AJ, tak sem dám výtah z článku. Slyšel jsem, že i dost kickboxerů záměrně "abstinuje" pár dní před důležitým zápasem a tady to máme vědecky podložené.
"Many athletes have questions about sexual
practice, and how sexual practice is applied so
as to maximize immune-function, physical
performance and quality of life. Should an
athlete abstain the night prior to a competition?
Should the athlete partake? Does sexual activity
increase or decrease testosterone levels? The
answers to these questions are in scientific
literature.
*Testosterone is responsible for muscle growth,
and muscle growth does not occur in its
absence. Consequently, athletes go to great
lengths to boost testosterone levels. Athletes
may take a variety of herbs, vitamins, minerals,
prohormones, prosteroids, and even illegal
steroids, to boost their testosterone levels and
performance.
Nutritional supplements are effective at altering
hormone levels, but many lose effectiveness
over time as the body down-regulates its natural
production of substances as a response to
exogenous influence. Muscle growth can stop
when this occurs.
Elevating testosterone levels naturally is
achieved by correctly applying sound training,
nutrition and sexual protocols. Scientific
literature and anecdote testify to the effects of
nutrition, exercise, and recovery on muscle
growth, but the correct application of sexual
activity as a method of boosting muscle growth
is only now being studied seriously.
Chinese researchers conducted a study in 2003,
and enlisted twenty-eight male volunteers to
abstain from ejaculation for a period of one
week. The participants were tested daily for
deviations on serum testosterone levels. The
Chinese study was the first to measure the
influence of ejaculation frequency on serum
testosterone levels, and the results are
provocative.
Researchers found that abstaining from
ejaculation for six days had no impact on serum
testosterone levels. On the seventh day, serum
testosterone levels peaked to 145.7% of
baseline, and then declined rapidly on the day 7,8.
Researchers believe testosterone declined on
day eight from the negative feedback
suppression of Leutinizing hormone secretion.
Leutinizing hormone is essential for testosterone
production, and LH determines free testosterone
levels. Suppression of LH would decrease serum
testosterone levels, returning them to baseline.
The study determined that the frequency of
sexual activity and ejaculation impacted
testosterone levels.
Putting It All Together -
Research is useful in as much as it can be applied
to provide direction. Based on the latest
scientific research on sexuality and sexual
behaviour as it relates to physiological function,
here is chronological sequence of action that
best utilizes the findings of the research:
1. Because testosterone levels are minimized in the
presence of elevated insulin levels, the pre-
workout meal should consist of lipids and
protein - both of which have negligible impacts
on insulin levels.
2. Research demonstrates that testosterone levels
rise as a response to sexual stimuli. Therefore,
an athlete could benefit pre-workout by being
exposed pre-workout to sexual stimuli. The
athlete could then exercise with increased
testosterone levels and aggression.
3. Post-workout, the athlete should consume a
protein drink with flax oil or olive oil. Lipids
facilitate the passive permeation of the cell wall
by sex hormones.
4. One hour post-exercise, the athlete should
achieve ejaculation. This will increase the natural
level of killer cells, thus increasing immune-
system function and enhancing recovery
abilities. The increase in killer cells will prevent
over-training .
You may also choose to postpone the
achievement of ejaculation for seven days so as
to maximize testosterone on a day of the
athletes choosing - i.e. on the hardest training or
competition day. If the athlete chooses this
protocol, ejaculation should be achieved on the
seventh day, post workout and according to the
above protocol, so as to avoid the negative
feedback suppression of LH demonstrated on
day eight of abstinence.
Natural testosterone fluctuations can be
manipulated only within the context of
hormonally correct exercise and nutrition. If
nutrition or exercise are inappropriate and if
insulin and estrogen levels rise, testosterone, GH
and IGF-1 will be adversely impacted and
muscle growth inhibited.
CONCLUSION -
*By postponing ejaculation for seven days,
testosterone levels spike. This testosterone
spike is thought efficacious for muscle
building and recovery."
