Apex Stretching and Hand Grip Strength:

Much can be said about the benefits of stretching – there are at least a couple reasons to do it!  And sure there’s been scientific evidence that stretching reduces the level of discomfort/soreness (Weppler et al, 2012) but there’s another side to that coin.

One research done March of this year looked at the effects of static stretching more thoroughly.

Static stretching is often utilized before and after the exercise or in this case both. While some claim it improves performance other claim it’s to prevent injuries. The majority of research in the field agrees on one thing – the effects of static stretches translate into strength loss more often than not!

Research of Eurico Peixoto Cesar and colleagues at the Laboratory of Biomechanics and Exercise Physiology tested this finding on Brazilian jiu-jitsu athletes specifically.

In order to get accurate estimates they tested grip strength dynamic and isometric kimono grip strength, range of motion along with passive torque. The static stretching routine consisted of the subject being seated with an arm close to the body, elbow at approximately 90 degrees while the researcher conducted the routine gradually until reaching the utmost discomfort point.

The results were conclusive – static stretching routines does increase Range Of Motion but they also reduce handgrip strength significantly, and the effect stays there!

A conversation on Vasper and Testosterone with A Pro Basketball Team

A conversation on Vasper and Testosterone with A Pro Basketball Team

Hello Art,

I was told someone at Vasper had told you to call us about some of the testing we have done pre/post use of Vasper. We did several small pilot studies on individuals with issues related to fatigue, sleep disturbances, etc.; something that athletes certainly suffer from when they are traveling and playing back to back games as the NBA does.

We have tested athletes in the NBA and see that when their anabolic hormones like testosterone begin to fall it increases their chances of injury. Testosterone is an important hormone for health of muscles, cardiovascular system, and brain function. From the basketball perspective, healthy levels of T are important for stamina (4th quarter performance), optimal eye-hand coordination (percentage of shots made in our world today and ability to toss a spear accurately into an animal 10,000 years ago), and probably most importantly, the belief that you can and will win (T activates brain sites that make men, and women, competitive). Winning increases T and is associated with winning streaks. Losing decreases T and is associated with losing streaks. Losing even decreases T levels in spectators.

As a scientist I see that low T, which is caused by over exercising and inadequate rest and regeneration leads to injury, which can be very expensive at all levels. Preventing these injuries is key to increasing the odds of winning. Keeping T levels within healthy ranges is key to staying healthy and preventing injuries.

The simple natural ways to keep T high are to: 1) reduce stressors (emotional-psychological, physical-overtraining) that increase levels of stress hormones (cortisol and adrenalin/noradrenalin), which suppress anabolic hormone levels (T and growth hormone-GH); 2) eat right at the right time of day; and 3) get a good nights sleep. If you don’t sleep well your T may be only half of what it should be. Oh yes, and 4) win. Winning increases T, losing decreases it.

In my limited experience with Vasper I found that it increased levels of T and IGF1 (marker for GH). We don’t know the mechanism, and it may be something as simple as enabling a better nights sleep.

Hopefully this isn’t too technical and you find it useful.

If you want to get baseline hormone levels on athletes we certainly can do that in easy to collect body fluids-saliva, urine dried on filter cards, or blood drops from the finger collected on filter cards. If you want more information on this please go to our web site at ZRTLab.com

Dr. Gladden’s Arterosil Study Results

Dr. Gladden’s Arterosil Study Results

Arterosil HP is an all-natural dietary supplement designed to support the body’s
vascular system for its optimal functions. In a previous human clinical
study, ArterosilHP was demonstrated to protect the endothelial
glycocalyx, the micro-thin slippery inner lining that prevents all blood
vessels from damage, in healthy subjects after they consumed a
standardized high sugar high fat meal. At the same time, the subjects
showed improved endothelial function with ArterosilHP supplementation as
measured by reactive hyperemia index (RHI).

In the current study, we hypothesize that ArterosilHP rapidly improves
arterial elasticity and pulse wave reflections through enhancing the
endothelial glycocalyx and its mediated arterial function. Nineteen
healthy human subjects (11 females age 22 to 64 and
8 males age 30 to 60) were randomly recruited for the open label single
blinded clinical study, which was co nducted at an independent
cardiology center on the Baylor Medical Campus in Plano, Texas. Their
vascular health condition was evaluated by using an FDA approved pulse
wave velocity diagnostic device, Max Pulse. The subjects arrived at the
clinic in the morning. Their baseline Max Pulse reading was taken at
approximately 2 hours (+/- 30 minutes) post consumption of a breakfast
of their choice. Immediately after the baseline reading one capsule of
ArterosilHP was swallowed. A post-dose Max Pulse reading was taken every
30 minutes for 3 hours, for a total of 7 Max Pulse readings (baseline,
30 min, 60 min, 90 min, 120 min, 150 min & 180 min +/- 5 minutes).
No food or liquid (other than small amounts of water as needed) was
consumed during the 3 hour testing period.

During each of the 7 tests for each subject the follow data were collected:

Percentage of Type 1 Wave Forms
Arterial Elasti city
Stress Resistance
Frequency Domain Power

Results

Percentage of Type 1 Wave Forms

84.2% of subjects experienced an increase in percentage of Type 1 Wave Forms
Average increase in percentage of Type 1 Wave Forms was 48.4% (p = .0032)
Mean time to maximum increase was 114 minutes

Arterial Elasticity

78.9% of subjects experienced an increase in arterial elasticity
Average percentage increase in arterial elasticity was 89.6% (p = .0081)
Mean time to maximum increase was 118 minutes

Stress Resistance

89.5% of subjects experienced an increase in stress resistance
Average percentage increase in stress resistance was 133.3% (p = .0016)
Mean time to maximum increase was 130 minutes

Frequency Domain Power

84.2% of subjects experienced an increase in frequency domain power
Average percentage increase in frequency domain power was 37.8% (p = .0003)
Mean time to maximum increase was 141 minutes

Conclusion

The current clinical study demonstrates that ArterosilHP supports arterial
health by rapidly improving the body’s percentage of type 1 wave forms,
arterial elasticity, stress resistance and frequency domain power. These
findings are consistent with our previous clinical results showing the
beneficial effects of ArterosilHP on the endothelial glycocalyx and
arterial function. Further analysis of these data will help us
understand the mechanisms and design new studies to evaluate long term
benefits of ArterosilHP supplementation on cardiovascular and
micro-vascular health.

Don’t be fooled by Artificial Sweeteners

Don’t be fooled by Artificial Sweeteners

Artificial sweeteners were first introduced in the late 70s
and early 80s giving people the hope that they could have their cake and
eat it too. However, many studies continue to show the dangers of these
sugar substitutes with symptoms including blood sugar increase,
gastrointestinal problems, seizures, dizziness, migraines, blurred
vision and obesity.
Low calorie and sometimes sweeter than
table sugar, artificial sweeteners like Splenda and Equal a Zero
Calorie sweetener have been appeal to those wanting to lose weight and
decrease their sugar intake. The scary truth is that these sweeteners
can be found in a variety of products like toothpaste, mouthwash, yogurt
and chewing gum. Saccharin commonly known by the brand name Sweet’n Low
can trick the body into releasing insulin which can pose problems for
those with diagnosed diabetes.
Common sweeteners to wat ch out f or include sucralose, saccharin,
neotame, aspartame, and acesulfame potassium. Steer clear of some
companies labeling their product as “natural”, although some sweeteners
are derived from naturally occurring substances most artificial
sweeteners are synthetic sugar substitutes. Try using honey, stevia, or
xylitol, a sugar alcohol found in some sugar-free gums, in small amounts
is great for baking.
In conclusion, sugar is hard to
avoid it’s everywhere even in places we never thought to look. Making
the better choice to eat some fresh organic fruit over a low calorie
snack bar might be the choice that saves you the headache-no pun
intended…okay maybe a little. Remember always check your back labels
and when in doubt go as natural as possible.
