- Energy requirement / energy systems
- Immediate energy requirement
- store ATP and phosphagenリン酸源 energy system
- 1-15sec (completely depleted within 20-30 sec)
- Short term energy requirement
- Glycolytic (break down of glucose)
- Glycogenolytic (break down of glycogen)
- 30-4 min
- Long duration energy requirement
- Oxidative (aerobic)
- activities lasting longer than -4min
- Immediate energy requirement
- Oxygen uptake
- VO2
- the volume of oxygen utilization by the tissues.
- Reflects the capacity to transport and utilize O2
- expressed…….
- Absolute –L O2/min
- Relative – ml O2/kg/min
- Resting energy generation exclusively aerobic (oxidative)
- VO2
-
Maximal oxygen uptake
- VO2 max considered as the “Gold Standard” of cardiorespiratory/cardiovascular fitness.
- Factors
- Ability to transport and deliver O2 to working tissues
- Ability of the muscles to take up and produce ATP aerobically
- Genetics
- Training
- Evaluation
- Incremental testing protocols
-
Rest-to-exercise transitions
- Requirement for ATP production immediately.
- Oxygen uptake increases rapidly.
- Reaches steady state within 1-4 minutes
- After steady state is reached, ATP requirement is met through aerobic ATP production.
- Initial ATP production through anaerobic pathways.
- ATP-PC system
- Glycolysis
-
Oxygen deficit
- (運動の最初は無酸素エネルギー系が優位なはずなのにoxygen deficitが出てくるのはなんでなんやろう?ATPの必要絶対量が安静時よりも圧倒的に増えるから、割合では有酸素運動系は低くても、有酸素を使ってるってこと??いや、違うな。ETCが回るまでには時間がかかるな。うーんわからん。2/2 2017)
- Lag in oxygen uptake at the beginning of exercise.
- Difference between O2 uptake in the first few min of exercise and an equal time period after steady state has been achieved.
- the requirement for O2 at the beginning of exercise increases, but oxygen consumption lags behind.
- Indicates that energy needs are being met anaerobically, how?
- Stores ATP and phosphagen activation
- Glycolysis
- Stored O2 on hemoglobin
- Stored O2 on myoglobin
- Trained and untrained subjects
- Trained subjects have a lower oxygen deficit
- Trained reach steady state quicker.
- Untrained 2-4 min
- Trained 1-2min 無酸素に頼らなくても有酸素でなんとかなるってことやな。
- Trained reach steady state quicker.
- Due to adaptations in either or both cardiovascular or muscular systems
- Trained subjects have a lower oxygen deficit
- Significance
- Aerobic bioenergetic system is activated earlier, so less reliance on glycolytic/glycogenolytic system
- Results in less production of lactate and H+
-
Recovery from exercise
- Oxygen uptake remains elevated above rest into recovery.
- Historically termed “Oxygen debt”, now known as “excess post oxygen consumption (EPOC)”. 運動後過剰酸素消費量
- Term used by A.V. Hill
- Repayment for O2 deficit at onset of exercise.
- Amount of oxygen consumption after cessation of exercise.
- Term used by A.V. Hill
- 2 phases of EPOC
- Rapid portion
- Steep portion of curve
- 0-3 min of recovery from exercise
- Slow portion
- Slower flatter portion curve
- 3-30 min of recovery from exercise
- Rapid portion
-
During EPOC
- Rapid portion
- Resynthesis of stored ATP and PCr (by what? aerobic?)
- Replenishing muscle and blood O2 stores
- Slow portion
- Elevated metabolic rate is due to elevation in
- heart rate, ventilation, hormones, body temperature
- Removal of lactic acid C3H6O3
- ~20% is converted to glycogen (glycogenesis)
- ~70% is oxidized to ATP and water (Krebs cycle – ETC?)
- ~10% is converted to amino acids (primarily leucineC6H13NO2)
- Elevated metabolic rate is due to elevation in
- EPOC (excess post-exercise oxygen consumption)
- terminology reflects that only ~20% elevated O2 consumption used to “repay” O2 deficit. ????????????
- Rapid portion
-
“excess post oxygen consumption (EPOC)”. 運動後過剰酸素消費量
- EPOC is greater following higher intensity exercise
- Higher body temperature
- Greater depletion of PC
- Additional O2 required for resynthesis
- Greater blood concentrations of lactic acid
- Greater level of glyconeogenesis
- Lactic acid is removed more rapidly with light exercise in recovery –optimal intensity is 30-40% VO2 max
- Higher levels of blood epinephrine and norepinephrine
- EPOC is greater following higher intensity exercise
- Metabolic responses to short-term, intense exercise
- Oxygen uptake increases linearly until maximal oxygen uptake is reached.
- VO2 max
- Physiological ceiling for delivery of O2 to muscle
- Affected by genetics and training
- Physiological factors influencing VO2 max
- Maximum ability of cardiorespiratory system to deliver oxygen to the muscle
- Ability of muscles to use oxygen and produce ATP aerobically
-
Lactate Threshold
- Early stages of incremental exercise, most energy is supplied from oxidative sources (La ~1-2 mmol/liter of blood)
- Lactate threshold : the point at which blood lactate rises exponentially (non-linear) during incremental exercise is referred to as “lactate threshold”
- Appears at 50-60% VO2 max in untrained subjects
- At higher work rates (65-80% VO2 max) in trained subjects
- a.k.a. Anaerobic threshold
- OBLA (Onset of blood lactate accumulation)
- Blood lactate levels reach 4mmol/L
- VO2 max + lactate threshold = very strong predictor of endurance performance.
- Very effective means in determining training intensity
- Mechanisms
- Low muscle oxygen
- Accelerated glycolysis
- Recruitment of fast-twitch fibers
- Reduced rate of lactate removal
-
Methods of estimating energy expenditure
-
Direct calorimetry
- the rate of heart production in an individual is directly proportional to the metabolic rate
- Process of measuring rate via heat production is called direct calorimetry
- Shortcoming : requires special chamber, expensive, slow.
-
Indirect calorimetry
- Direct relationship in O2 consumed and heat produced in body.
- Carbohydrate and fat metabolism requires O2 and produces CO2 and water.
- Measuring the O2 consumed and CO2 produced at is an indirect estimate of metabolic rate and caloric expenditure.
- most common –Open-Circuit Spirometry 肺活量測定
-
-
Energy Expenditure
- Respiratory Exchange Ratio (R / RER)
- R : is the ratio of oxygen consumed and carbon dioxide produced (VCO2/VO2)
- Only measured during steady state. This is important because only during steady-state exercise are the VCO2 and VO2 reflective of metabolic exchange of gasses in tissues.
- O2 requirement and CO2 produced during the oxidation of CHO/FAT/PRO differ greatly.
- Fat oxidation requires more O2 to be metabolized because carbs contain more O2
- Respiratory Exchange Ratio (R / RER)
-
Estimation of fuel utilization during exercise
- Respiratory exchange ratio (RER or R) R=VCO2/VO2
-
R for fat (palmitic acids-an example of fatty acid.)
- C16H32O2 + 23O2 ➡︎ 16CO2 + 16H2O
- R=VCO2/VO2=16CO2/23 O2 = 0.70
-
R for carbohydrate (glucose)
- C6H12O6 + 6O2 ➡︎ 6CO2 + 6H2O
- R=VCO2/VO2=6CO2/6O2 = 1.00
- During a 30 minute run an individual consumes 90 liter of oxygen and expires 72 liters of CO2.
- (VCO2 / VO2) = R. (72 L CO2 / 90 L O2) = 0.75
- 4.74 kcal x 90 L O2 = 426.6 kcal
- 1 L O2 30 Min 30 min
- RER of 0.75 =17% CHO / 83% FAT
- 426.6 kcal x 0.83 = 353.58 kcal from FAT
-
353.58 kcal fat x (1 gm fat / 9 kcal) = 39.28 grams FAT
- 426.6 kcal x 0.17 = 72.52 kcal from CHO
- (72.52 kcal) x (1 gm CHO / 4 kcal) = 18.13 grams CHO
- Exercise intensity and fuel selection
- Protein contribution as an energy source is relatively low, 2-5% daily.
- May increase up to 15% during long duration exercise
- Is not included in R values.
- What determines fuel being used during exercise?
- Diet
- Exercise intensity
- Low intensity exercise (less than 30% VO2 max)
- Fats
- High intensity exercise (more than 70% VO2 max)
- Carbohydrates
- Low intensity exercise (less than 30% VO2 max)
- Exercise duration
- Protein contribution as an energy source is relatively low, 2-5% daily.
- Crossover concept
- best describes the shift from fat to CHO metabolism as exercise intensity increases. Due to:
- Recruitment of fast muscle fibers
- Increasing blood levels of epinephrine
- best describes the shift from fat to CHO metabolism as exercise intensity increases. Due to:
- Shift from carbohydrate to fat metabolism during prolonged exercise
- Due to an increased rate of lipolysis (triglycerides ➡︎ glycerol + FFA)
- Stimulated by rising blood levels of epinephrine
- Is low intensity exercise best for burning fat?
- At low exercise intensities (~20% VO2 max, R=0.8)
- High percentage of energy expenditure (~67%) derived from fat
- However, total energy expended is low (3kcal/minこの値はどこから?)
- Total fat oxidation if also low (2kcal/minこの値はどこから?)
- 30min of exercise
- TOTAL 3kcal/min=90kcal
- 67% fat=60kcal. 33% carbs=30kcal
- At higher exercise intensities (~60% VO2 max, R=0.9)
- Lower percentage of energy (~33%) from fat
- Total energy expended is higher (9kcal/minこの値はどこから?)
- Total fat oxidation is also higher (3kcal/min)
- 30min of exercise
- TOTAL 9kcal/min=270kcal
- 33% fat = 90 kcal, 67% carbs = 180 kcal
- Optimal intensity for exercise can be misleading
- unless you consider both rate of energy expenditure and percentage contribution.
- At low exercise intensities (~20% VO2 max, R=0.8)

留学3ヶ月前に学校を変えた理由
少し長くなりますが、僕に起こった学校探しでのトラブル(?)を紹介します。留学を目指す方に参考になれば幸いです。
僕は留学開始する3ヶ月前、つまり2016年4月30日までUNC Charlotteに進学する予定でした。この学校を選んだ理由はモータースポーツドライバーやライダーを支えるアスレチックトレーナーとなるために最も適した環境があると思ったからです。
UNC Charlotteはアメリカの南部で特に人気のモータースポーツNASCARの本拠地に位置し、Program DirectorもNASCARの方と繋がりを持っていました。この学校に進学する以外にはない!と思っていました。
その学校を少しでも早く見たいという思いで4月末にCampus VisitとOpen Houseに行ってきました。留学の3ヶ月前に一度現地に足を運んで、Program Directorに会って話をして、留学開始までの勉強意欲を維持させることが狙いでした。(この意気込みが良くも悪くも思わぬ結果を招くことに。。。笑
さぁ、出発!初の1人アメリカ!
乗り換えでLos Angelsに到着!待ち合わせ時間は11時間!笑
Charlotteに到着!空港に到着するもCenter City行きのバスが全く分からず立ち往生。笑
無事にUNC Chralotteに到着して1日目はCampus Visitに行ってきました。超広大なキャンパスを歩くことに四苦八苦しました。
とりあえずキャンパスが超広いです!端から端まで歩くと30分以上はかかります。笑 僕はスーツケースコロコロしながら全部歩きました。笑
2日目はCharlotteのCenter Cityへ行ってNascar hall of fameを見学しました!
Nascar hall of fame前の横断歩道はチェッカーフラッグ!
全米でも21番目の大都市ということで人で賑わっていました。Bank of Americaの本社があったり、Carolina Panthersのスタジアムがあったりと見所たくさんのCharlotte観光でした!
ここまでは良かったんです。笑
さて、3日目にOpen Houseに行った時にProgram Directorと話す機会がありました。
出国までにメールで単位移行や授業の履修について十分に確認していましたが、直接会って話を聞いて確かめることが目的でした。
面接の時間は30分ほど取っていただきました。そこで、事件が発生。笑
2016 fallに取得するつもりだったクラスが既に30人待ちというのです。
メールで散々確認してきたのに、なぜ30人待ちの事実を教えてくれないんだ?笑 このクラスを取れないと3万7500ドルほど4年間払うことになる。それはさすがにできない。
もし、campus visitに来なければ 学期が始まる直前に取るべきクラスが取れないという事態になるところでした。そうなってしまったら、取りたいクラスを取れず高い学費を払って泣く泣く学校を変えざるをえなかったでしょう。間一髪で大惨事を逃れました。
(あくまで私の直感ですが)この学校のAthletic TrainingはInternational studentの受け入れに慣れてないので要らぬ苦労をしそうだなと思いました。年間3万7500ドルを払って学ぶ価値はないな。と思いました。
帰り道の間に、「本当にこの学校で良いのだろうか?」と悩みました。モータースポーツドライバーを支えるトレーナーとなるためには必ずしもUNC Charlotteに留学する必要はないと結論づけました。
(決してUNC Charlotteのprogramを否定しているわけではありません。あくまで私の経験であり、主観的意見です。)
よし、学校変えよう!
残り期間でできる限りの行動を起こして最高の選択をしよう!
と決心したのが帰りの飛行機、日本に到着する直前でした。
5月1週目
学校を探し始めたのですが、2週間ほど全く情報がつかめないまま焦って時間だけが過ぎる日々が続きました。
しかし、立命館大学在学中に得た人脈で良い学校を紹介していただくことができました。
新しい留学先はThe University of Southern Mississippiです。
ATCの方がいらっしゃる留学サポート会社にお世話なります。
学校を選んだ理由は
①締め切りが6月1日だったこと(学校を探し始めたのが5月1週目)。
②学費が比較的安いこと。Internationalで1年9000ドル程度(UNC Charlotteは1年18000ドル)
③日本人ATCがプログラムを修了していること
④南部に位置するので比較的NASCARが人気である事。
が主な理由です。
ちなみに私はUSMで奨学金を得てIn-state tuitionで留学を開始する予定でした。
過去にUSMを修了した日本人ATCもこの奨学金を得て留学していたそうです。
しかし、この奨学金を私は得る事ができませんでした。
理由はSecond Bachelorです。私は立命館大学を卒業してからUSMへ留学します。2つ目の学士、つまりSecond Bachelorを取得する学生に対して奨学金は降ろせないという学校の判断でした。8000ドルほど授業料が変わるので4年間で32000ドルほど差額が出ます。(あくまで私の経験です。全ての方が全ての学校で該当するわけではありません)
これを頼りにしていたので、かなり痛手ですが、嘆いても仕方ないので私はこれからできる事をやっていくのみです。
学士取得後にATC取得を目指して留学する方は奨学金の対象になるかどうか学校側にしっかりと確認してください!
痛い目あいますヨ!笑
そして僕は現在、Master Programへの進学へ向けて準備中です。いろんな学校の条件を比べながら、検討中です。
腰をどっしり落ち着けて勉強したいなぁ。。。笑
でも、常に試されてるからね。置かれた環境でベストを尽くそう!

6 Common Misconceptions About Cancer
conspiracy (theory) :
(徒党を組んだ)陰謀、謀議、陰謀 |
Myth #1 :サメはガンにかからない&サメの軟骨組織を貯めればガンが治る
ウソ。
angiogenesis : 血管新生.
tumors need a supply of blood. Cut off the blood supply and you could theoretically starve the tumor.
aflatoxin B1 : アフラトキシン (aflatoxin , AFT) とは、カビ毒(マイコトキシン)の一種でB1、B2、G1、G2を始めとする10数種の関連物質の総称。
shysters : いかさま師、いんちき弁護士
Myth #2 If you have cancer you should avoid eating sugar. ガンにかかったら砂糖を食べないようにするべきだ。
ウソ。直接的な原因にはならない。
not eating sugar doesn’t actually seem to give cancer cells access to less glucose
MYTH #3 : taking a ton of antioxidants will prevent cancer. 抗酸化物質はガンを防ぐ
注意が必要。
nanny : ナニー 《女性名; Ann(e), Anna の愛称》.
Sometimes destructive chemicals called reactive oxygen species get loose in out cells. They damage crucial cellular machinery. DNA damage can lead to cancer
抗酸化物質は活性酸素を中性化する。活性化酸素はDNAにダメージを及ぼす作用があるので抗酸化物質の摂取は効果的。に思えるが、研究ではまだ抗酸化物質がガンの発生率と関連があるかは証明できていないそうです。 抗酸化物質はガンが存在する場合には進行を早める可能性もあるとのこと。
melanoma : メラノーマ、黒色腫
MYTH #4 : Biopsies help cancer spread
dislodge : (…を)移動させる、除去する、追い払う、撃退する
One study of several hundred breast cancer patients showed that about 30% of the time, biopsies did shake loose bits of tumor.
there’s a catch : 落とし穴、問題、難点がある
もちろんミスによってガンの断片も残る可能性はあるが、その小さな断片ではガンは進行することはないそう。
でも、例外のガンがあります。
testicular cancer actually does have a decent chance of spreading after a biopsy.
MYTH #5 : cancer is a modern disease
ウソ。cancer has been found in 3,000 year old human remains & dinosaurs
wood smoke : 木材燃焼煙
MYTH #6 : Cancer is killing more people around the world
ガンが多くの人の命を奪っているように見えるが、多くの要素が複雑に絡み合っていることを理解しなければいけない。栄養環境が整って、医療も充実すれば寿命が延びる。このような環境下においては昔の死因であった餓死などが少なくなる。でも、人間はいずれ死ぬ。
ガンになる原因は山ほどあるのだ。
