「戴口罩跑步為什麼一下就喘❓」
「戴口罩可以順便訓練肺活量⁉️」
雖然世界衛生組織WHO呼籲“運動時不建議配戴口罩”
但是我國人口密集,疫情也隨之嚴峻
在這樣的景況下
「運動時到底能不能戴口罩?」
似乎就成為一個熱們的話題🧐
今天🐑老師,就來帶大家解開戴口罩的運動迷思~
-
🏃♂️「為什麼戴口罩運動會覺得很喘❓」
呼吸困難感屬於主觀感受,每個人的感覺強度不同。
➡️戴上口罩時,口罩會吸收身體散發的熱量與水氣,使口罩內的濕度增加(想像是進入蒸氣室,很難呼吸)➡️呼吸時會吸入先前呼出的潮氣量的一部分,該部分潮氣量耗盡了氧氣而富含二氧化碳,間接的死腔就會增加(不知道什麼是死腔?#跑步時到底該怎麼呼吸)➡️經過重複的呼吸和運動強度增加,每分鐘通氣量也跟著提升(呼吸的頻率加快)➡️最後再加上流汗口罩越來越濕,你就會呼吸更加困難。
💡所以會喘不是因為氧氣不足,而是因為二氧化碳提高導致每分鐘通氣量增加,再加上溼度會大幅度降低口罩的舒適度,所以讓你感覺難受
🏃♂️「戴口罩可以訓練肺活量❓」
現有的數據表明,儘管隨著運動強度增加,戴口罩會使人們對呼吸的感知努力度跟著提升,但對於運動過程中的血氧、心律和其他生理參數影響卻很小,即使在非常劇烈的運動中也是微乎其為,甚至就連自覺努力、衰竭時間都沒有顯著差異,因此戴口罩運動可能對運動耐力表現無法產生重大的影響。
🏃♂️「戴口罩運動需要注意什麼❓」
1️⃣潮濕的口罩必須隨時更換,避免口罩防護力下降
2️⃣放慢速度與步伐,隨時注意身體狀況
3️⃣心血管疾病患者需醫生許可
4️⃣阻塞性肺部疾病患者需醫生許可
5️⃣長期抽煙或老年者需斟酌
⚠️目前的文獻多半是針對健康成年人
雖然實驗過程中受試者沒有發生身體不適的狀況,但是仍然不能排除發生的可能性
⚠️因此還是強烈建議若非健康成年人請勿輕易嘗試,而且僅適用於中低強度運動與短時間下之運動,執行時需要有他人陪同
✅最後,還是要呼籲
此文不是鼓勵你戴口罩出門運動
而是理性思考戴口罩運動背後的意義與原因
✅防疫期間“在家運動”
才是最安全而且舒適的選擇!

【KETO Fat Chance of Performing Better】/【生酮飲食對於運動表現的影響】
The Ketogenic Diet may help some shed a little weight, but it might not be good news for athletic pursuits.
A study published in the Journal of Sports Medicine and Physical Fitness chronicled 16 men and women who ate a low-carb, keto-style diet (i.e., getting less than 10% of one’s energy from carbs) for 4 days, then measured their anaerobic exercise performance on a Wingate cycling test. The second phase of the study conducted the same test after participants spent 4 days on a higher-carb diet (both diets had the same number of calories).
.
✔The results: Participants performed worse after the low-carb diet.
------------------------------------------
【生酮飲食對於運動表現的影響】
生酮飲食可以幫助一些人減重減脂,但對於追求運動表現來說可能不是件好事。
發表於Journal of Sports Medicine and Physical Fitness 的一項研究,紀錄了16位男性與女性,在分別進行生酮飲食(每日碳水化合物攝取佔比小於10%)與高碳飲食(相同總卡路里),連續4天後進行Wingate cycling test 無氧運動進行比較。
.
✔結果顯示:參賽者於生酮飲食後表現沒有高碳飲食好。
------------------------------------------
衝刺、舉重這類型的高強度運動需要使用無氧磷酸根系統,主要的供應源是碳水化合物,碳水也就成為了運動表現關鍵因素之一了,也就不難推論這項研究的結局。
.
⚠️不過這份研究有兩個令人疑問的點:
.
1)生酮飲食的效果,必須經過身體的轉換期進入生酮狀態(酮症),時間長短因人而異,通常前3天會特別精神不好,4天的短期變換飲食,生酮飲食還沒發揮不說,身體還處於適應階段,運動表現當然不會好。
.
2)生酮飲食常作為減重減脂的方式之一,在減脂過程身體能量本身就不足,在這份研究裡被提出討論與運動表現到相關性,是不是有點沒意義呢?
.

Tips for all the runners. #2016 #3
Answer to the #2 post - Evidence suggest that it is training intensity and not duration that is the most important factor in improving VO2max.
Interval Training
→ Repeated exercise bouts, with brief recovery periods in between.
→ Length and intensity of the work interval depends on what the athlete is trying to accomplish.
→ A longer work interval requires a major involvment of aerobic energy production.
→ A shorter with more intense work interval provides greater participation of anaerobic metabolism.
↔ Thus, in order to improve VO2 max, the interval training should generally utilize intervals longer than sixty seconds to maximize the involvement of aerobic ATP production.
↔ It is generally believed that high-intensity intervals are more effective in improving aerobic power than low-intensity intervals.
↔ Improvement maybe due to the recruitment of fast-twitch fibers (types lla and llx) during the high-intensity exercise.

A new addition to the ever popular Combat Conditioning classes is a pool recovery session ran by strength and conditioning coach, Andrew Wood. A various number of workouts from swimming to shadow boxing underwater can part of the session.
Coach Andrew Wood has been using this method for years with our fighters and has added it to our Combat Conditioning Classes.
Recovery in any sport is a crucial aspect of training. While some athletes have a preferred method or routine that fits their training program, recent studies have provided some scientific evidence that aquatic-based recovery workout method may actually be more beneficial over another.
Any pain-inducing inflammation from MMA, Muay Thai or any other various types of training -- whether it be muscle soreness, contusions or joint pain-- has to be flushed out of the area. Because you float in water, you can work your muscles and engage in movement, intense or relaxed, while submerged without adding further wear and tear to the troubled areas as you would on land.
An aquatic-based recovery workout reduces muscle fatigue and post-exercise pain, partly because the hydrostatic properties of water help decrease inflammation, according to a study in the “International Journal of Sports Medicine.” Dynamic range-of-motion exercises combined with diaphragmatic breathing also decrease muscular tension and increase relaxation.
