maconha catabolsa?

[nandorocha]

bom.. tenho conhecidos q usam e teimam dizendo que nao influencia na academia.. pelo q eu ja li sobre o assunto realmente a maconha de uma certa forma retarda o crescimento dos musculos.. eai alguem sabe algo a respeito?

porfavor nao fugir do assunto do tópico, sem discurssões sobre a droga e só comentarios ligado ao assunto!

Obrigado! ;]

Marijuana

Cardiovascular consequences of marijuana use.

Sidney S.

Kaiser Permanente Medical Care Program, Division of Research, Oakland, California 94612, USA.

This review describes what is known about effects of marijuana and cannabinoids in relation to human physiological and disease outcomes. The acute physiological effects of marijuana include a substantial dose-dependent increase in heart rate, generally associated with a mild increase in blood pressure. Orthostatic hypotension may occur acutely as a result of decreased vascular resistance. Smoking marijuana decreases exercise test duration in maximal exercise tests, increases the heart rate at submaximal levels of exercise. Tolerance develops to the acute effects of marijuana smoking and delta9-tetrahydrocannibol (THC) over several days to a few weeks. The cardiovascular responses that occur in response to THC are mediated by the autonomic nervous system, with recent findings also demonstrating that the human cannabinoid receptor system plays a role in regulating the cardiovascular response. Although several mechanisms exist by which marijuana use might contribute to the development of chronic cardiovascular conditions or acutely trigger cardiovascular events, there are few data regarding marijuana/THC use and cardiovascular disease outcomes. A large cohort study showed no association of marijuana use with cardiovascular disease hospitalization or mortality. However, acute effects of marijuana use include a decrease of the time until the onset of chest pain in patients with angina pectoris; one study has shown that marijuana may trigger the onset of myocardial infarction. Patients who have coronary heart disease or are at high risk for the development of CHD should be cautioned about the potential hazards of marijuana use as a precipitant for clinical events. Research directions might include more studies of cardiovascular disease outcomes and relationships of marijuana with cardiovascular risk factors, studies of metabolic and physiologic effects of chronic marijuana use that may affect cardiovascular disease risk, increased understanding of the role of the cannabinoid receptor system in cardiovascular regulation, and studies to determine if there is a therapeutic role for cannabinoids in blood pressure control or for neuroprotection after stroke.

Q. Can occasionally smoking marijuana hurt athletic performance?

A. "The athlete who uses marijuana, even on a casual basis, experiences very significant effects that have a direct bearing on athletic performance," says Roy T. Bergman, M.D.

Bergman, who has served on the medical staff for U.S. Olympic and Pan American Games teams, points to studies showing that marijuana decreases exercise capacity. It inhibits sweating and temperature control. The drug impairs coordination, steadiness and accuracy. It slows reaction time and interferes with judgment of speed, time and space relationships. Marijuana can also cause short and long-term memory loss and prolong learning time. In addition, regular use is strongly associated with apathy, loss of ambition, difficulty in concentrating, and a decline in academic performance.

These negative effects have not stopped all athletes from taking the drug, however. For example, 36% of athletes involved in NCAA competition had used marijuana during the previous year according to one study. And in a survey of elite women athletes, 17% of the respondents said they too had used the drug in the last year. Other studies have concluded that marijuana is second behind alcohol as the substance most commonly abused by athletes.

Marijuana users often argue that a smoke now and again, or perhaps a spiked chocolate chip cookie, is less harmful to performance than alcohol. However, both can be quite damaging to success in sport. And in one respect, marijuana may be more of a physical threat than alcohol: The psychoactive ingredient in marijuana, THC, enters the fat tissue where it can be gradually released into the blood to cause effects 24 to 36 hours after the drug was last used.

Vejam bem, na verdade creio que existam pouquissimos estudos cientificos analisando os efeitos da maconha na hipertrofia. Por isso há muita informação controversa. Exemplo, uns dirão que ela diminui os níveis de testosterona e hormonios sexuais ou negarão isso:

3) NEW STUDY FINDS POT DOESN'T LOWER TESTOSTERONE

A new study by Dr. Robert Block at the University of Iowa disputes the commonly held notion that marijuana alters the level of testosterone and other sex hormones.

The study contradicted a widely publicized 1974 study by Dr. R.C. Kolodony, which reported decreased testosterone levels in men who smoked marijuana chronically.

The U. of Iowa study found that chronic marijuana use had no effect on testosterone, luteinizing hormone, follicle stimulating hormone, prolactin and cortisol in men or women.

Noting that six other studies had failed to show lowered testosterone levels in men, Dr. Block concluded: "It appears that marijuana, even heavy use of the kind that's typical in the United States, doesn't alter testosterone levels."

However, he cautioned that heavy use might have other adverse effects, including "possible effects on reproductive function and mild, selective cognitive impairments associated with heavy, chronic use."

Block's study is published in Drug and Alcohol

Dependence, Vol. 28: 121-8 (1991).

Mas na minha opinião, maconha e musculação não combinam.
