教練我要減脂,所以我要開始跑步了嘛?
其實到現在,相信還是許多人還是會有減脂就是要慢跑的想法,甚至還會這樣教學。這大概也是最常被問的問題。
☘️低強度長時間有氧,幫助脂肪燃燒?
執行後你會發現,跑步真的可以減脂。但!其實所有的運動都可以減脂,而不是減脂要跑步,增肌要重訓。那為什麼會有減脂要跑步的傳說呢?
最早在2001年Exercise Physiology: Theory and Application to Fitness and Performance書中提到
圖一、運動強度與營養素使用百分比之關係
👉隨著運動強度愈強,身體愈高比例使用醣類作為能量消耗。
圖二、運動時間與營養素使用百分比之關係
👉隨著時間愈久,身體愈高比例使用脂肪作為能量消耗。
因此,奠定了大家認為,低強度長時間運動,最能幫助脂肪的消耗!也是慢跑被認為最佳燃脂運動的原因。
☘️被忽略的細節 總能量消耗
不知道大家有沒有發現,上面兩張圖所表達的,是百分比,忽略了總能量的判斷。
根據2001年The effects of increasing exercise intensity on muscle fuel utilisation in humans文獻證實
圖三、運動強度、能量消耗與其能量供應源之關係
👉隨著運動強度愈強,能量消耗愈多。但是在其中脂肪酸的消耗變動較少,反而是醣類的消耗大幅增加。因此也符合前面所看到,醣類耗損的百分比增加。
因此,證明了不論運動強度多寡,都會消耗脂肪。而隨運動強度愈強,消耗醣類能量愈多。
☘️那是否高強度運動,對減脂無更大幫助?
根據2015年Abdominal fat reducing outcome of exercise training: fat burning or hydrocarbon source redistribution文獻提出
圖四、平時與餐後,能量與肌肉、脂肪的奪取關係。
👉運動後,肌肉會奪取更多的能量來源,迫使脂肪組織得到的能量減少,降低脂肪儲存,進而減脂。
因此,高強度運動對於減脂可能比中低強度更有效果。
☘️慢跑的價值
跑步不再具有減脂特別好的優勢,那為何還是現在主要訓練項目之一?
依照運動處方簽,健康體適能的目的在於
1. 提昇肌肉與肌耐力
2. 提昇心肺能力
3. 提昇柔軟度
4. 改善身體組成
這也是當學員踏進健身房,我們最應該先知道他的目的。提昇生活品質?減肥?改善酸痛?還是想增加運動表現?
而慢跑非常適合訓練肌耐力與心肺能力!此外對於新手運動員或高血壓、心血管疾病患者,無法採取高強度高負荷訓練時,慢跑會是一個非常好的運動。
☘️結論
慢跑對於提昇肌耐力、心肺能力都有很好的效果。對減脂也有一定的功效。
但如果以減脂為目的,其實大部分運動都可以,甚至愈高強度運動效果愈好,因此只要選擇自己喜歡的運動即可!
所以!並非減脂就是只能跑步唷!
☘️吉米小補充
但其實可以看到圖三的肌肉中三酸甘油脂,利用率明顯較低。文獻中並無明確的說明,目前認為較大的可能性為:高強度運動活化了無氧糖解,影響了肌肉中游離肉鹼下降,導致脂肪酸無法進入粒線體,脂肪酸氧化能力下降。
雖然近代研究普遍認為中低強度運動不在是減脂首選,但如果高強度運動可能會下降脂肪酸氧化能力的角度,慢跑也許真的是減脂最佳選擇!

【都市頑疾】以為糖尿病離你很遠?
⭐檢視自己的生活壞習慣
⭐糖尿病主要由不良習慣引致
#星期二提升正能量
你是糖尿病高危族嗎?
吃糖太多會患糖尿病?常喝甜味飲料會增加糖尿病風險嗎?你是糖尿病高危族嗎?
來看看你有沒有糖尿病風險成因:
☐ 三餐不定時
☐ 飲食太豐盛,少吃粗糧
☐ 嗜甜食、含糖飲料
☐ 容易肚餓及頭暈目眩
☐ 有吸煙或飲酒習慣
☐ 活動量不足
☐ 工作壓力大
☐ 肥胖,BMI超過25
☐ 睡眠不足 / 失眠
☐ 有糖尿病家族史
☐ 年齡 ≧ 45歲
☐ 患有高血壓或高血脂
☐ 曾患妊娠糖尿病
糖尿病分為一型及二型,一型患者因自體免疫問題令身體無法製造足夠胰島素;而較多人患上的二型糖尿,一般發生在中年或較年長人士身上,多與肥胖有關,不良飲食習慣令胰臟工作過度,或壓力大令壓力荷爾蒙過度分泌,造成胰島素阻抗而患上糖尿病。如果你有5個或以上風險成因,就要注意身體症狀,定期進行身體檢查,戒除不良飲食習慣,讓糖尿病離你越來越遠。

Are you at risk for diabetes?
Consuming too much sugar can lead to diabetes? Drinking sweet drinks regularly can increase your risk of getting diabetes? Are you at risk for diabetes?
Let’s take a look at risk factors:
☐ Having irregular meals
☐ Lack of coarse grains in diets
☐ Sweet tooth
☐ Feel dizzy when hungry
☐ Enjoy smoking and drinking alcohol
☐ Lack of exercise
☐ Stressful work
☐ Obesity, BMI exceeds 25
☐ Lack of sleep/insomnia
☐ Hereditary
☐ Aged 45 and above
☐ High blood pressure and cholesterol
☐ Gestational diabetes
There are two types of diabetes mellitus: type 1 and type 2. Type 1 patients cannot produce sufficient insulin due to the problems with their immune system. Type 2, which is more common, normally happens to elderly folks.
Type 2 diabetes is also associated with obesity and unhealthy dietary habits, which cause the pancreas to overwork. Excessive secretion of stress hormone, too, can inhibit the secretion of insulin, which in turn leads to diabetes.
If these risk factors seem familiar to you, then you should start paying attention to your health and go for regular body check-ups. Getting rid of all the unhealthy eating and drinking habits is the best preventive measure to keep diabetes at bay.

Episode 5: CYCLING IN SINGAPORE TOUR WITH GOPRO HERO 9 Health benefits of regular cycling
Health benefits of regular cycling
Cycling is mainly an aerobic activity, which means that your heart, blood vessels and lungs all get a workout. You will breathe deeper, perspire and experience increased body temperature, which will improve your overall fitness level.
The health benefits of regular cycling include:
increased cardiovascular fitness
increased muscle strength and flexibility
improved joint mobility
decreased stress levels
improved posture and coordination
strengthened bones
decreased body fat levels
prevention or management of disease
reduced anxiety and depression.
Back to top
Cycling and specific health issues
Cycling can improve both physical and mental health, and can reduce the chances of experiencing many health problems.
Obesity and weight control
Cycling is a good way to control or reduce weight, as it raises your metabolic rate, builds muscle and burns body fat. If you’re trying to lose weight, cycling must be combined with a healthy eating plan. Cycling is a comfortable form of exercise and you can change the time and intensity – it can be built up slowly and varied to suit you.
Research suggests you should be burning at least 8,400 kilojoules (about 2,000 calories) a week through exercise. Steady cycling burns about 1,200 kilojoules (about 300 calories) per hour.
If you cycle twice a day, the kilojoules burnt soon add up. British research shows that a half-hour bike ride every day will burn nearly five kilograms of fat over a year.
Cardiovascular disease and cycling
Cardiovascular diseases include stroke, high blood pressure and heart attack. Regular cycling stimulates and improves your heart, lungs and circulation, reducing your risk of cardiovascular diseases.
Cycling strengthens your heart muscles, lowers resting pulse and reduces blood fat levels. Research also shows that people who cycle to work have two to three times less exposure to pollution than car commuters, so their lung function is improved. A Danish study conducted over 14 years with 30,000 people aged 20 to 93 years found that regular cycling protected people from heart disease.
Cancer and cycling
Many researchers have studied the relationship between exercise and cancer, especially colon and breast cancer. Research has shown that if you cycle, the chance of bowel cancer is reduced. Some evidence suggests that regular cycling reduces the risk of breast cancer.
Diabetes and cycling
The rate of type 2 diabetes is increasing and is a serious public health concern. Lack of physical activity is thought to be a major reason why people develop this condition. Large-scale research in Finland found that people who cycled for more than 30 minutes per day had a 40 per cent lower risk of developing diabetes.
Bone injuries, arthritis and cycling
Cycling improves strength, balance and coordination. It may also help to prevent falls and fractures. Riding a bike is an ideal form of exercise if you have osteoarthritis, because it is a low-impact exercise that places little stress on joints.
Cycling does not specifically help osteoporosis (bone-thinning disease) because it is not a weight-bearing exercise.
Mental illness and cycling
Mental health conditions such as depression, stress and anxiety can be reduced by regular bike riding. This is due to the effects of the exercise itself and because of the enjoyment that riding a bike can bring.
