Titolo: Subacquea ed esercizio fisico

Ciao a Tutti!!!
Leggendo il libro di Leone Tarozzi sulla decompressione, mi sono venuti
alcuni dubbi riguardo alle attività fisiche da abbinare alla subacquea.
Infatti nel testo succitato si include l' intensa attività fisica effettuata
nelle 24 ore prima dell' immersione nei possibili fattori di aumento del
rischio decompressivo... Quindi sarebbe da sconsigliare la palestra la sera
prima dell' immersione, o anche la semplice partita di calcetto?
Sarebbero poi da evitare tutte quelle attività che implicano eventuali
(micro) traumi, ad es. le Arti Marziali ( pensate all' allenamento al sacco
o al condizionamento tipo makiwara, per non parlare del combattimento anche
solo "da palestra"...), il calcio e la semplice corsa su asfalto...
E che dire poi del trasporto delle decine di chili di attrezzatura sub,
magari su impervi sentierini prima dell' immersione!!! ;-)))))))))
Voi, che ne pensate? Come vi regolate? Dovremmmo forse darci tutti allo yoga
ed assoldare degli sherpa per quando andiamo in mare??? :-))))))))
Ciao!

> non c'entra una mazza, ma cos'č il makiwara?
E' un'asse di legno verticale, alto circa un metro e mezzo, eventualmente
ricoperto con della corda per gli ultimi 20-30 cm, usato dai praticanti
(seri) di Arti Marziali per allenarsi a portare le tecniche, specialmente di
pugno, con efficacia! Impari soprattutto a tenere i pugni ben chiusi.
Inoltre rinforza le "nocche"!

The ABCs of Fitness
- - - - - - - - - - -
BY THE GUE STAFF
The fitness and diet industry is a multibillion-dollar marketing machine
that deluges the public with advertisements on a daily basis. Many of the
messages sent try to create the illusion that fitness can be achieved
through maximum eating and minimum effort, with just the addition of a
little pill or a new exercise gadget. Most people know that such methods
will not work, but unfortunately, many still hopefully pursue them while
others have become too weary and frustrated to do anything at all.
To help make exercise and nutritional choices easier, each issue of dirQuest
will focus on sorting out the mixed messages to find the aspects of healthy
living that are supported by the most reliable research.
ABC's of Nutrition
The marketing efforts of large companies and industries dominate the way
people think about nutrition. From the highly esteemed four food groups of
our grade school days to the multi-million dollar "it does a body good" and
"mustache" milk advertising campaigns, few people on the planet are beyond
the grasp of the marketing skills of huge food manufacturers. Several
decades of questionable, marketing-based "research" funded by these
organizations, cloud the minds of most so-called experts, forcing
individuals to carefully weigh any information presented. Certainly
educational information created by the marketing division of the dairy
industry might have some value; however, it is nearly inconceivable that
this type of information would promote a diet that does not include healthy
doses of their products. In many cases, fundamental nutrition information
has been relayed to students by teachers who use create educational support
materials created by food advertisers to "assist" the educational process.
Add these nutritional complications to a medical field with very little
nutritional training and you are nearly guaranteed a web of confusing
information. Consider, for example, that on average physicians receive less
than three hours of nutritional training during four years of medical
school. Yet the Surgeon General indicates that the majority of disease can
be corrected or prevented with proper diet and exercise. Given the
overwhelming evidence that most of our current nutritional habits are
responsible for a reduced quality of life, why do we continue this assault
on the health of our bodies? A powerful combination of habit, marketing
power and convenience conspire to shield people from a growing realization
that the popular American diet is killing us in unprecedented numbers. With
all the debate and confusion surrounding responsible nutrition, some
fundamental and relatively uncontested tenets to healthy living stand clear.
Meat Consumption
Despite heavy advertising, it has become increasingly difficult for the meat
industry to hide the high correlation between health risk and meat
consumption. A diet that supplies most of its protein needs from plant
rather than animal sources seems to decrease the risk for developing
cancer.1 Also, a simple review of the healthiest populations in the world
illustrates that "one fact that emerged consistently was the strong
correlation between heavy flesh-eating and short life expectancy."2 The
upside? Many fitness trainers and nutritionists advocate that you will have
more strength and energy during your (shortened) life. But, consider
findings in the Yale Medical Journal that "flesh-eaters showed far less
endurance than the abstainers (vegetarians), (due) entirely to the
difference in their diet"3.
Fruits and Vegetables
An overwhelming amount of evidence indicates that abundant quantities of
fresh fruits and vegetables are essential to a healthy diet. With as much as
70% of all cancer cases being diet-related4, it is essential to remain aware
of the great life-giving benefit found in fresh fruits and vegetables.
Consuming organic foods can eliminate or at the very least significantly
reduce the pesticides found in common food portions. Fresh fruits and
vegetables are best, while frozen are better than canned which are robbed of
many nutritional benefits.
Hydration
Most people are at least partially dehydrated on a daily basis, stressing
the kidneys and greatly impacting the body's self-healing ability to filter
the blood. This purification system can operate efficiently only if the
water intake is sufficient to carry away wastes. Dehydration also likely
increases DCS risk (and subsequent damage) by increasing blood viscosity.
Consumption of at least eight glasses a day is recommended, with athletic
activity or hot climates demanding from one to two gallons a day.
Carbohydrates
The optimal fuel for the body is found in carbohydrates. However, carbs have
received a certain negative stigma when people focus on the sugar rush
associated with simple carbohydrates. The simple "carbs" are rapidly
converted to sugar and may result in a "crash" or energy low. Simple carbs
can be replaced (brown rice and whole wheat bread rather than white rice and
white bread) or combined with complex carbs or protein to provide a longer,
more consistent fuel source. In general, any processed carbohydrate foods
are likely to create this rush, while more natural foods produce a slower
metabolic release.
Protein
A great deal of evidence demonstrates that the excess protein consumption
within the American diet encourages many negative health (and environmental)
issues. In fact, it is difficult to design any experimental diet with
adequate calories that is actually deficient in protein5, including a strict
vegetarian diet. The cholesterol, fat, toxins and disease carried by the
common protein sources of meat and dairy produce well-researched and
significant health concerns, including the increased risk of osteoporosis,6
that is mostly hidden from the public, and heart disease. Excellent sources
of less toxic protein include beans, nuts, greens and tofu.
Fat
An increasing trend of consuming high fat, processed foods continues despite
significant evidence indicating that it is a leading cause in a wide range
of diseases, including heart disease, stroke and many cancers. Such diseases
occur most often to meat eaters, then dairy eating vegetarians and least
frequently to non-dairy consuming vegetarians.
Nutrition can be a complicated issue, especially when mixed with powerful
marketing campaigns. However, individuals should never let this confusion
lead them to believe that there are no acceptable or beneficial guides to
nutritional health. A diet high in wholesome foods- organic fruits and
vegetables, whole grains, legumes and water, with little processed foods
containing fat, cholesterol, sodium and sugar, is a simple and beneficial
plan. The benefit to even relatively minor dietary changes can generate
amazing benefits in health and lifestyle improvements.
ABC's of Exercise
While diet can certainly make a huge difference in the quality of life, the
picture is incomplete without a consistent exercise regime. Regular exercise
is capable of forever changing one's health and well being. The secret to
enjoying the benefits is to develop a program that matches ability and
comfort. Certainly peak levels of fitness require significant time and
effort, but amazing benefits can be found in the simplest of exercise
routines. Everybody, regardless of age or present physical condition, can
exercise. Your medical and orthopedic background will determine the type and
intensity of your exercise routine, but not your ability to exercise. From
bike riding and running to swimming and even fast walking, there are many
exercise choices.
Aerobic Vs. Anaerobic Exercise
Aerobic exercise is a sustained, rhythmic large muscle activity that does
not require more than a low or moderate intensity (energy) level. Some
aerobic activity can be performed continuously without undue respiratory
discomfort. Aerobic exercise is essential for cardiovascular health and
should be practiced a minimum of three days per week. While the aerobic
system is responsible for prolonged athletic activity, anaerobic exercise is
utilized in short power surges such as sprinting, jumping or weight lifting.
Anaerobic or mixed exercise routines should be performed at least twice a
week. In truth many aerobic exercises exceed the aerobic threshold and
become anaerobic. Individuals who push themselves too far in exercise
routines or who are new to aerobic exercise will often bridge into times of
anaerobic effort as they develop an increased aerobic level of fitness.
People striving for general fitness and cardiovascular health should focus
on aerobic exercises, adding anerobic exercise such as weight-lifting for
bone density, muscular strength and resilience.
It is important for each person to discover what motivates them, since
regular activity is essential for true fitness. Many individuals develop a
favorite exercise routine, while others like more variety. Some find that
morning exercise limits the endless reasons not to exercise as the daily
grind overwhelms them. Early morning exercise is a great way to start the
day and leaves one energized with a great feeling of accomplishment.
However, others prefer afternoon or early evening routines. Whatever the
time chosen, make the most of personal improvement time by developing
greater mental clarity and a healthier body. Several very popular exercises
include swimming, biking, running and weight lifting.
Swimming
Swimming is an excellent exercise that does not fatigue the body with
gravity-pounding stress. Efficient swimming requires good form, and those
with very little technique should take at least a couple basic lessons to
improve the quality of their swim. Swimming helps develop excellent
cardiovascular fitness and exceptional comfort in the water, both of which
are especially beneficial for divers. By mixing swimming sprints with lap
exercises, the benefits of cardiovascular and muscle building exercise are
blended.
Biking
Biking is a favorite exercise among both casual and dedicated fitness
enthusiasts. Biking allows exercisers to adjust their routine by increasing
distance or intensity for more rigorous programs. Biking can be very
satisfying and include scenic rides and social interaction with other
riders. A good helmet and a fairly inexpensive bike, and riders are off to
explore their surroundings. Riders can choose between mountain bikes for
intense off-road excursions or road bikes for distance and endurance.
Running, jogging or sprinting
Running is a convenient exercise that can be accomplished in nearly any area
without the need for special equipment, save a good pair of running shoes.
Individuals can tailor their workout by mixing a routine of walking, fast
walking, jogging and sprinting according to their comfort and ability. A
technique gaining popularity involves hard spurts of activity interspersed
with reduced effort, such as sprinting followed by jogging in an ongoing
cycle. Those with limited fitness levels should work up to the rigors of
this program and may wish to alternate jogging and fast walking.
Furthermore, alternating cycles of intense effort can be worked into other
routines such as swimming and biking.
Jumping rope
Rope jumping is an amazingly flexible method of exercise that can provide
significant levels of fitness within a relatively short time period. Jumping
rope is also convenient because it can be done almost anywhere, even when
traveling. As with many forms of exercise, new participants will find the
effort to be more anaerobic in nature. With minimal practice longer segments
of jumping will become possible, increasing the aerobic impact. At the onset
many people may be heavily challenged by short jumping periods of one minute
with a one minute break. Some studies indicate that only six minutes of rope
jumping is equivalent to 30 minutes of jogging, making this exercise a great
time saving routine for especially busy days. New participants can start
with one minute cycles and work up to three and then five minute jumping
segments with one minute rest breaks.
Weight Lifting
Weight-bearing exercises give us the strength to move efficiently in our
day-to-day movements (like standing up on the dive boat with a set of double
steel 104s). They also keep our bones healthy by encouraging bone growth and
warding off bone weakness. All exercise routines should be preceded by a
warm-up and stretching period. Preparing the muscles for any form of
strenuous exercise is essential to a safe and injury-free routine. Daily
stretching, possibly as part of a yoga routine, is an excellent method to
clear one's mind while preparing the body for physical stresses. Warming up
for an exercise routine should take between five and ten minutes. The
exercise routine should begin within ten minutes of the initial warm-up,
preferably sooner. Many health benefits are thought to be associated with a
good stretching regime. From increased circulation to mental health and
injury prevention, stretching is an essential way to start any exercise
routine. Fitness routines that mix aerobic, weight bearing and flexibility
exercises tend to provide the greatest levels of general health. Most people
find that they become accustomed to a regular exercise routine much more
quickly than they anticipate. The hardest part of new exercise is the
acclimation period at the onset of training. Once individuals get beyond the
initial couple weeks of soreness, new levels of energy and health can begin
to restore the body. After experiencing the benefits of true health, most
people would never consider returning to low levels of personal fitness.
Remember, the better you treat your body, the better it will treat you.

Andrea invece di prendere per il culo chi della sicurezza per se eper gli
altri ne ha fatto un modello di vita guardati nello specchio forse dietro di
te vedrai l'aureola .
Se però vai a parlare con tutti i docenti iperbarici in giro per il mondo
nessuno consiglierà le stronzate che tu hai detto , a patto che non siano
praticate da persone che abitualmente fanno certi allenamenti e che dopo
moltissine esperienze non abbiano maturato una tolleranza maggiore della
media di noi comuni mortali all'Azoto .
Se invece hai dati tecnici veri e non parole , su persone normali ,
comunicaceli altrimenti stai zitto e butta la tastiera nel cesso .
Io non sono un inqisitore , sono 15 anni che ripeto che un ottima forma
fisica è alla base dell'immersione , ma quando tu parli di persone che
normalmente la domenica si fanno un -90 non parli di
comuni mortali .
Parla col Dott . Longobardi che di prove col Doppler ne ha fatte sicuramente
+ di mè e senti cosa ti risponde , dopo ritenta con Brauzzi che trattava i
Consubi
Alla fine fai come vuoi
Buona fortuna
Alessandro
Pensaci

 possibili.
Andrea, Andrea, ma e' chiaro che il moto dopo l'immersione
favorisce la MDD!
Ma perche' credi che lo Schumi dopo aver vinto il gran
premio con la Ferrari agiti cosi' la bottiglia di Sciampagne?!
Lo fa per liberare le bolle, o no?
Scusa ma non e' che quel tuo amico di Trieste, di cui per
ragioni di privacy non si puo' (Corrado docet  :-) dire il
nome (ma soltanto il cognome: Arena), ti abbia fatto il
lavaggio del cervello con le sue teorie estemporanee sulla deco? :-))))
Ciao
 
Giovanni
PS: quand'e' che si fa una immersione insieme?
