Alang˛ mnajem cerita bab gastrik. Mau juga tanya si jag bab pantang larang org gastrik dlm hidup berdiet ni. Esp dlm nak selarikan dgn
cara hidup mcm yg si jag cerita dlm latest pos.
Memang ada pantang ke? Setahu aku org gastrik ni jgn lambat makan je. Kelak binasa
Good question,aku akan menjawabnya. Tapi,disclaimer, I'm not a doctor or even a sport science dietitian, all the information given here is based on my own searching and consulting sports science expert and also self experiment, I am the test subject of my own project. Another thing, I used to have astma and also gastric ulcer,atau yg orang kita panggil gastrik. Used to,now no longer.
Up to this point, there is no CLEAR EVIDENCE or relation between caffeine consumption and Stomach and Duodenal Ulcers (Peptic Ulcers) or even dyspepsia juga dipanggil heart burn. The debate is still on, but there is no clear link between the two. It was last reviewed in 1999 by 1. Boekema, P.J. et al. Scandinavian Journal of Gastroenterology, 34 Suppl 230, 35-39, 1999. They finally conclude that “Coffee promotes gastro-oesophageal reflux, but is not associated with dyspepsia. Coffee stimulates gallbladder contraction and colonic motor activity”. gastro-oesophageal reflux = heart burn. Asid peptik dalam usus masuk balik ke dalam tekak...tuh bila makan banyak rasa cam nak muntah...atau 'naik balik makanan'.
Another thing I would like to point out, Sports Science and Medical Science is 2 separate school. In Sports Science, the studies & solution are for people who are conducting sports or athletic activity, regardless of level. Medical science,works for both...but usually for the 'average' human being. An example, a normal doctor will advice you not to consume no more than 250 mg of Vitamin C per day. Tapi, if you are an athlete or exercise regularly, strenuously...mcm jogging 3 kali seminggu,main futsall,main rugby...weight training,marathon etc...even Tae Kwan Do etc...than the 250mg does not apply. Sports Science doctor would advice,4000 mg a day! Why? Because the amount of 'wear-and-tear' the body goes through by exposing your body to those activities.
Using caffeine as a performance catalyst is not something new and is not without controversy. The effect of caffine on sports peformance is significance,up to the point.the Olympic World Anti-Doping Association (WADA) banned the substance .. i.e caffeine but in 2004,removed it. WADA's excuse that caffine will give unfair advantage. Tapi,kalau ko fikir balik, kalau pelari pecut tuh nak minum kopi....before pertandingan...? Memang dia kaki minum kopi pun. So,WADA came to thier senses and removed the ban.
Tapi AWAS, kalau ko jenis hari2 pekena kopi...I mean before ko start dalam pilot project ni,ko mmg peminum kopi tegar...pagi petang siang malam,then the effect will be less effective. Badan manusia ni, the prolong exposure of a substance will have build an immune towards it.
Aku jarang2 minum kopi, dalam satu minggu...minum kopi bila nak exercise etc jek, lain2 masa...air kosong...teh. Teh pun,bukan teh tarik, tapi peppermint or green tea or any other tea,and usually before tido. So,caffine effects on my body is higher.
Satu lagi, caffeine ni penyerap air,diuretic. Kalau nak pakai kopi untuk eksesais sebagai pemangkin, make sure eksesais ini dibuat diawal pagi,waktu sejuk2,so you will not suffer heat exhaustion. Research tentang penggunaan kopi sebagai pemangkin pembakaran lemak ini dijalankan di US dan Eropah,negara cuaca sejuk, test subjek mereka pun lari dalam sejuk,jadi masaalah dehydration tuh x nampak sangat.
Lepas eksesais, terbaik kalau boleh minum air kelapa fresh. R&D telah menjumpai,air kelapa mempunyai lebih banyak elektrolit,garam mineral etc dari minuman2 elektrolit lain. Air Kelapa ni digunakan oleh 'Special Forces' dalam hutan sebagai penawar racun...etc. Next best thing, air2 elektrolit macam 100 Plus.
Ok,apasal x boleh air kosong jek? Camni. Ko dah eksesais, garam2 habis semua kelua...dalam peluh,kira mineral deficit dah nih. Bila ko tambah air kosong,dalam badan...ia akan create an imbalance, mineral imbalance yg sangat merbahaya dan mengakibatkan kematian. So, electorlit drinks are good for the first phase of hydration, lepas ko dah minum tuh, baru ko minum air kosong.
Panjang dan detail, tapi nak kena cerita jugak. Takut2 ramai yg buat benda2 ni selama ni main ikut2 and mengelakan masaalah 'gila isim'.Belum lagi masuk bab eksesais dan diet untuk mereka yg ada masaalah gastrik.

Recommendations:
Do not use any caffeine for three days (or more) prior to an event. Start 3 to 4 hours prior to your event and consume 3mg - 6mg of caffeine per kg body weight (that's 210mg to 420mg for a 150lb athlete).* This is a large amount of caffeine, so be sure to experiment before you do this with incremental levels of caffeine.* If you are not trained, then you are better off not using caffeine at all.
If you choose to load with caffeine prior to training or an event, make sure to use products which clearly list total caffeine content. Many energy drinks list caffeine, green tea or guarana on the label but do not list total caffeine content. Most of these drinks offer minimal levels of caffeine (5mg-40mg).
WADA's removal of caffeine from its banned substance list does raise some serious concerns. If abused caffeine can be detrimental and dangerous. Caffeine's actions on the CNS, excitory response and potential as a diuretic can all cause serious damage if abused. We strongly urge all athletes wanting to use caffeine to do so under extreme caution.
*Excess caffeine can cause anxiety, irritability, delirium and hallucinations. Caffeine increases core body temperature and heart rate. Consult a physician before using caffeine prior to exercise.
Typical Caffeine amounts:
Soda: 50mg caffeine
Cup of Coffee: 50 - 150mg caffeine
Cup of tea: 10 - 50mg caffeine
Guarana: active ingredient is caffeine (8% to 15%)
Green tea herb: active ingredient is caffeine (0% to 15%) I.E. 100mg of Green Tea extract provides between 0mg and 15mg total caffeine content.
