Širdies stiprinimas

[Vilius]

Aišku, kad nebūtinai.Turėtum minimalių medicinos žinių tai ir žinotum, kad egzistuoja tokie dalykai, kaip ŠSD, maksimalus širdies susitraukimų skaičius, rezervas ir t.t. Pagal kurį apsiskaičiuoji individualų savo širdies darbą ir jį derini prie treniruočių, kai širdis dirba maksimaliu režimu ji vargsta, kai dirba, nors patankėjusi, ji nepakankamai dirba, yra tam tikri individualūs parametrai ir intervalai, kuriuose širdis dirbdama stiprėja.Viskas yra sąlygina- tiek pritūpimai, tiek bėgiojimas- gali ir gydyti ir žaloti.

Pas mane yra šiek tiek padidėjęs kraujospūdis. Gydytojo (sporto medicinos centre) komentaras buvo:štangų nerekomenduoju, nes jos dar labiau didina spaudimą. Išvada-širdžiai teigiamos įtakos tikrai nedaro...

Ne nu... Ką tu čia man aiškini?

Įrodyk, kad štangų kilnojimas nestiprina širdies.

Visų pirma reikia mokėti štangas kilnoti.

O su ta išvada

Man vienas daktaras sakė, kad nuo grūdinimosi susitrauks pimpaliukas. Išvada - grūdinimasis pimpalo ilgiui teigiamos įtakos nedaro...
Tikriausiai gydytojas pasakys išgerti nuodų, išgersi, taip? 

Atsiunčiau dvi nuorodas, tikriausiai jų nepakako. Įdomu ar išvis skaitėte.

Tai eik į sporto salę ir stiprink savo širdį su štangom, sėkmės.

Cardiovascular Stresses and Adaptations.

When an individual lifts a heavy weight, several events occur t h a t stress the
cardiovascular system. O n e of t h e first is that the contracting
muscles compress t h e blood vessels in those muscles and
increase their resistance to blood flow. This increase in
resistance causes a dramatic increase in blood pressure. There
are reports of blood pressure increases as high as t w o to four
times normal values. These pressures place a tremendous load
on the heart, which has to p u m p harder to compensate and
continue t o deliver blood not just t o t h e working muscle but to
all areas of t h e body.
After long-term weight training, the heart adapts by
increasing t h e thickness of the muscular wall of the left
ventricle. The increase in heart muscle mass enables
the heart to deliver blood efficiently in spite of temporary
blood pressure increases during exercise.
Requirements for Cardiorespiratory Fitness.
An issue of importance to the s t r e n g t h / p o w e r athlete is cardiorespiratory
fitness, sometimes confused w i t h aerobic fitness or endurance.
Aerobic/endurance fitness relates directly to the efficiency of
oxidative metabolism and is not t h e same as cardiorespiratory
fitness—a healthy heart and lungs. Specifically, aerobic fitness—
the oxidative mechanisms of A T P generation for prolonged,
low-intensity exercise—does not contribute to power
performance, either directly or indirectly. Exercise scientists
trained in academic programs where aerobic exercise is the
focus will usually say that aerobic training is necessary for all athletes. Exercise scientists trained in programs where
anaerobic exercise is t h e focus will argue against that point
vehemently, as studies have shown that aerobic training can
actually interfere w i t h maximal strength and power gains.
These arguments should be evaluated w i t h three things
in mind. First, cardiorespiratory fitness is p r i m a r i l y a health
issue, and competitive athletes do not normally fall within the
population which needs to be concerned about heart attack
prevention. (The fact is that elite competitive athletes are not
concerned about their health; they are concerned about
winning.) Individuals w i t h below-average levels of
cardiorespiratory fitness are in fact at a higher risk for
developing high blood pressure and cardiovascular disease, both
of which are certainly detrimental to health and performance.

Basic stuff you need to know

Competitive athletics has already selected against these
individuals. People for w h o m aerobic training addresses a
problem that does not exist would be better served by devoting
the time to skill acquisition, more complete recovery, or a
hobby.
Second, although a degree of cardiorespiratory fitness is
needed to more efficiently recover from sets or workouts,
supply needed oxygen and n u t r i e n t s to the working muscle,
and carry away waste products fast enough for adequate
recovery, a V 0 2 max only 2-3 m l / k g / m i n above normal is
adequate for accomplishing this task in s t r e n g t h / p o w er
athletes. This is n o t a tremendous improvement in
cardiorespiratory fitness above normal level. In fact, anaerobic
training alone, over time, develops aerobic fitness to just above
average levels and therefore negates the argument for including
aerobic training in power athletes' programs. Limited earlyseason
aerobic w o r k would be sufficient to solve any endurance
problems that might be encountered. If power athletes stay in
the weight r o om year-round, there will be no real need for long
slow distance w o r k outside the weight room.
Finally, research regarding the use of endurance training
for strength/power athletes rather strongly suggests that
endurance w o r k interferes w i t h all the parameters such athletes
are concerned w i t h developing. The most recent research into
interference deals w i t h the tendency of aerobic training to
reduce the magnitude of anaerobic improvement when the two
are done together or in close sequence. And this research does
not consider what happens to existing power performance. It
has been well k n o w n since t h e 1980s that a program of
endurance training will cause large reductions in vertical jump
height. For athletes whose sport requires a mix of anaerobic
and aerobic/endurance training, studies suggest that separating
the two by as little as an hour blunts the negative effect of the
endurance workout. The studies, and practical experience,
indicate that aerobic training may be included at low volumes
and intensities, but the question remains as to whether it
contributes to effective training and time management.
Research examining aerobic-anaerobic interference
typically looks at the effects of long slow distance-type training
upon strength performance. It is quite likely that interference
between the t w o occurs due to differences in the nature of the
activities and the metabolic pathways involved. It is possible
that endurance exercise activities that more closely resemble
weight training would not have the same detrimental effect on
power and strength performance. We suggest that highintensity
glycolytic exercise not only drives improvements in
VO2 max, but that this type of t r a i n i ng can be used alongside
weight training programs w i t h o u t significantly reducing
strength gains.
The distinction between cardiorespiratory fitness and
aerobic training i s particularly important. Anyone w h o has
ever done a 20RM set of deadlifts knows that there is a
cardiorespiratory component t o t h e work . The depression in
O2 saturation produced by this high level of glycolytic intensity
i s much more disruptive to t h e homeostasis of oxygen
transport and utilization t h a n traditional low-intensity types of
aerobic training. This may be what drives t h e moderate
improvement i n VO2 max seen i n traditional weight training
programs, and the high degree of improvement associated with
high-intensity glycolytic exercise.



There are a number of different types of cardiac hypertrophy.
The normal, unadapted heart has a "normal" ventricular chamber size and
muscle wall thickness (A). Long-term resistance training increases the
thickness of the muscle walls without significantly changing chamber size
(B). Long-term endurance training increases chamber size without increasing
muscle wall thickness (C). Pathological hypertrophy results in increased
chamber size and reduced muscle wall thickness (D

Na tai kad tam tavo šaltiny aiškiai parašyta,kad kraujo spaudimas pakyla 2-4 kartus, kas mano atveju gali baigtis liūdnai.... Tas tekstas tik įrodo medikų man sakytus žodžius.  O frazėm "nieko neišmanai" tai siūlau šiame forume nesimėtyt.

Širdies stiprinimas yra šūdo vertas, jei "nestiprinamos" kraujagyslės. Todėl ir pareina širdis nuo štangų, nes anaerobinis darbas padidina širdį, o kraujagyslės nepajėgios tiek kraujo prapumpuoti. Pats patyriau, teko mesti štangas ir krosiukais bei krosu užsiiminėti. Jei duodi daug anaerobinio darbo, reikia duoti ir aerobinio, kitaip batai, atsilenksi ir niekas nepastebės (nes *** viena burna lyšna žemėje reikalinga).

Tegu patirtis kalba už save...

“Weight Training Increases Blood Pressure”
Myth. Plenty of studies have shown that weight training decreases systolic and diastolic
blood pressure. Granted, your blood pressure does increase during a heavy set of Squats
or Deadlifts, but it goes back to normal after your set is done. This is actually how your
cardiovascular fitness improves with strength training (without having to do that dragging
cardio ). Instead of boring you with research, here are actual case studies from StrongLifts
Members who decreased their blood pressure with Stronglifts 5x5.
First, StrongLifts Member Will (page 11) – he had borderline high blood pressure before he
started StrongLifts 5x5 His doctor told him to do cardio because weight training wouldn't
help. Will listened, did cardio, but didn't stick with it because obviously, cardio is boring.
Why do you think they put TVs and magazines in the cardio area of each gym? Will then
discovered StrongLifts 5x5, started the program and within a year his blood pressure
plummeted from 138 to 100 without any kind of cardio, rather Squatting and Deadlifting.
In case you think this only applies to younger guys, consider SL Member Bob (page 185)
who is 3x the age of Will – 64 years old. Like Will he had high blood pressure when he
started, 138. 2 years after having done StrongLifts 5x5 his blood pressure has plummeted
to 100. Again, without doing any kind of cardio, but just by increasing his Deadlift – which
he does with 410lbs at age 64, while he never did any Deadlifts before. Interestingly, Bob
claims that his blood pressure actually increased when he was doing cardio.
Another case, StrongLifts Member Norman (page 180) who is 44. His blood pressure was
almost 150/100 when he had a heart attack prior to discovering StrongLifts 5x5. At his last
checkup his blood pressure was 125/70. He hasn't been on any medication for a year, and
he does Squats and Deadlifts with 500lbs. He even won his first powerlifting meet.
Many dumb doctors who are supposedly educated will claim that weight training increases
blood pressure and that it isn't healthy. Yet the American College of Sports Medecine – the
largest sport medicine and exercise science organization in the world – recommends it.
Here's a quote from their website...
Using free weights as part of an exercise program can be a safe and effective means of
improving strength and fitness for all ages and fitness levels, for men and women. They
provide a stimulus for muscle-fitness development, which can increase the amount of
calories you burn (body fat reduction), increase muscle size, enhance muscular
strength, power and endurance, and increase strength of bones. Increased muscle
strength can also have a positive impact on quality of life for older adults.
The ACSM would obviously not recommend weight training if it was bad for your health.
Do StrongLifts 5x5 as laid out for 12 weeks, your blood pressure won't increase, it will
decrease just like it did for my StrongLifts Members.

Vel gausiu ban tikriausiai...

Reiktų prisiminti ne tai ką pirmosios med. kursuose mokeisi, bet anglų kalbos žinias. Dar toje pačioje pastraipoje minima yra kraujo spaudimas (blood pressure), o ne susitraukimų skaičius .
