各位樓主,
我自已都食佐差不多一年 蛋白粉,真係有d驚:funk: 。咁有經驗(口既)帥兄都食到有事,希望兩位帥兄早日康復。亦希望各位樓主食得健康。

(星島日報報道)心臟病是港人的第二號殺手,有心臟病專科醫生透露,近月有兩名「大隻佬」健身教練兼亞運健美獎牌得主,竟因服食坊間健康食品及自設餐單,食到腎衰竭及影響心臟,只剩半條人命,須入深切治療部。醫生警告,九成九的坊間健康食品或成藥沒經過科學驗證,監管上存有問題,亂服藥嚴重可致肝衰竭,每年均有三至七宗因服坊間的成藥而出事的個案。

香港公立醫院心臟醫生協會主席劉育港透露,兩月前有兩名任職健身教練的亞運健美獎牌得主,為擁有良好身體綫條,不但每日吃駝鳥蛋、每周喝二十公升清水,更曾服食坊間的健康食品,以致身體出現問題,找他求診,最後更須入深切治療部。他表示,兩人「食到差點死」,患上腎功能衰竭及影響心臟,虛弱得拿着十磅物件十分鐘已全身疼痛。

兩人曾獲亞運健美獎牌

心臟病專科醫生譚劍明補充,有健身人士會吃高蛋白質、雄激素的健康食物,多款食物混合一起,或會致腎衰竭,最終導致心臟衰竭,而過量服雄激素也會致荷爾蒙失調,影響心臟健康。他呼籲,市民不應超出自己能力,胡亂服藥「谷」肌肉,因坊間的健康食品或成藥沒經過科學驗證,監管上有問題,品質不受保證,或令身體機能下降。

另外,香港公立醫院心臟醫生協會於今年七月,以問卷訪問了三百七十七名冠心病患者、曾患上心肌梗塞、心紋痛或曾進行相關心臟手術人士。調查發現,近三成半人曾不理醫生指示而自行停藥,當中近四成停藥超過一星期,逾一成更停藥超過一月,譚劍明警告此乃高危行為,增加復發、甚至死亡的機會。劉育港指出,國際文獻證實,提早停藥令血管支架再栓塞機會增加五十七至一百六十一倍,死亡率增九倍。

調查顯示六成八人稱停藥主因是「一時忘記或疏忽」,三成六人卻表示「覺得自己已經痊瘉」或「覺得間中停藥無所謂」而自行停藥,而兩成四則「擔心藥物副作用」。值得注意的是,四成二人曾因心臟病復發而要入院或再做手術,四成四曾復發兩次或以上,其中近一成人復發超過四次,情況令人擔心。雖然有七成九人稱擔心復發,但仍有四成半人沒依照醫生或營養師指示改善飲食習慣。醫生建議,應注意飲食和運動,如最少每周做三次帶氧運動,每次三十分鐘。

Sports Nutrition

Ron Maughan (Loughborough University, UK) chaired the sports nutrition symposium that included speakers Susan Shirreffs (Loughborough) and Stephen Wong (Chinese University of Hong Kong). Although no new information was presented the following summarizes the content from the presentations:

‧ The Maughan Rule to supplementation is "if it works then it is probably banned, and if it is not banned then it probably does not work!" :funk:
‧ Athletes can obtain their nutritional requirements from a balanced diet ensuring that the essentials of carbohydrate, protein, fat, vitamins, minerals, fiber and water are attended to.
‧ Carbohydrate intake guidelines of 5-7 g/kg body mass in moderate training and up to 10 g/kg during heavy training.
‧ Protein intakes >1.7 g/kg/day are not necessary.
‧ Energy intake is best measured by monitoring body weight and skin folds.
‧ Acute post-exercise creatine supplementation and high carbohydrate intake increases muscle glycogen at three and six days post exercise.
‧ 2% body mass loss (as a measure of hydration status) is the level above which detrimental  performance effects will occur, but this figure may be less if heat is involved. (especially temperature >30ºC)
‧ Replace fluid losses at 150% of weight loss. (We note that this percentage is contentious given the possible risk of hyponatremia).
‧ The effectiveness of fluid replacement is improved with higher concentrations of Na+, which can be obtained from rehydration fluids (although Na+ concentration is limited by palatability) or food. K+ concentration is not an issue.
‧ Individualize fluid and recovery regimens
‧ Pre-match meals consisting of low glycemic index foods sustain carbohydrate availability and maintain blood glucose levels during exercise.
‧ Post-game glycogen repletion is best achieved with high-glycemic index foods.
