QC (Quick Charge) is not your normal protein.
It’s designed specifically for endurance racing—light, fast-absorbing, and easy on the stomach.

Why protein during a race?

• Prevents muscle breakdown when carbs run low
• Supports muscle function & recovery even mid-race
• Helps delay fatigue and maintain mental focus

Why QC stands out?

• Superior bioavailability & absorption → works when you need it most
• Portable race-friendly sachets, no heavy shakes
• Designed for performance, not just recovery

QC = Protein for racing, not just protein.

1. Muscle Repair & Adaptation During Training and Racing
Endurance activities like long-distance running or cycling cause metabolic stress and micro-damage to muscle proteins. Consuming protein helps stimulate muscle protein synthesis and supports recovery and adaptation to training loads.

2. Preventing Muscle Breakdown (Gluconeogenesis)
When carbohydrate stores drop—typically after ~90 minutes of sustained exercise—the body may start using amino acids from muscle tissue for energy (via gluconeogenesis), which weakens muscles and performance. Providing protein during the event helps prevent this “muscle cannibalization.”

3. Supporting Training Adaptation & Endurance Performance
Research suggests that endurance athletes benefit from daily protein intakes of around 1.8 g/kg body weight, with potentially higher needs (~2.0 g/kg) on low-carb or high-intensity training days. Post-exercise protein (approx. 0.5 g/kg) further aids recovery, repair, and adaptation.

4. Modest Performance Gains with Protein Supplementation
A recent meta-analysis found protein supplements may modestly increase lean mass and significantly improve time to exhaustion when compared to carbohydrate-only fueling—allowing athletes to sustain effort longer.

What Makes QC Stamina (Quick Charge) Stand Out

• Engineered for race-day use, not typical post-workout recovery shakes. It’s designed to be digestible, lightweight, and usable intra-race to maintain muscle function and stamina.
• Helps sustain muscle output, particularly during long efforts when carbs alone may not suffice.
• Promotes mental sharpness and reduces central fatigue—critical in later stages of ultra-distance events.
• Convenient fueling: portable sachets (take one every 2–3 hours) that minimize gut distress and are easy to integrate into race nutrition.

Summary: Why Protein (and QC Stamina) Matters During Races

Aspect	Why It’s Important	How QC Stamina Helps
Prevent muscle breakdown	Helps avoid using muscle protein for energy	Provides amino acids intra-race
Support adaptation & recovery	Promotes repair and mitochondrial adaptation	Delivers protein during prolonged effort
Maintain performance & mental focus	Prevent fatigue and maintain strength	Balanced formula supports body & mind
Gastrointestinal tolerance	Avoids race-day stomach issues	Designed to digest easily and be lightweight

QC Stamina is clearly formulated to fill a unique niche in race fueling—providing bioavailable protein support during long endurance efforts when traditional carbs may fall short. Its emphasis on easy digestion and sustained energy distinguishes it from typical proteins intended for post-exercise recovery.

If you’re an advocate of injury-free running, you likely place a high value on warming up before your run and cooling down afterward. However, this alone is not enough. You might also engage in interval training to further improve your abilities, but there’s a chance you’re not executing interval training correctly.

Therefore, it’s worth ensuring a proper understanding of interval training and “recovery intervals.”

It’s well known that the benefits of interval training lie in the recovery intervals. Recovery intervals are defined as recovery periods following high-intensity training, allowing the body to prepare for the next about of high-intensity exercise. Recovery intervals can involve slow jogging, brisk walking, or resting, and their purpose is to help the body recover to maintain or improve performance in subsequent exercises.

When discussing recovery during interval training, three variables need to be optimized:

1. Recovery time
2. Mode of recovery
3. Activities during recovery

To answer these questions, consider the following factors:

• Who is training?
• What type of training is being performed?
• What is the training goal?

Today, we will discuss this important topic of interval training!

 

Interval Training Structure: Repeats and Recovery

In “interval training,” the “interval” refers to the recovery periods between fast runs, and “repeats” refers to the specific durations of fast runs separated by specific paces.

“Repeats” represent the fast-running parts, while “recovery intervals” represent any distance and time between them.

When designing training schedules, recreational runners are recommended to structure recovery in two ways:

• As a set distance (e.g., 16 x 200m with 200m slow jogging recovery)

Choosing the correct recovery length is a broad topic that covers all possible situations and outlines the fundamental science behind what happens during recovery so you can make more informed decisions in your training.

Generally speaking, interval training can be divided into two categories:

1. Repeats performed at intensities above your lactate threshold or critical speed
2. Repeats performed at intensities close to or slightly below your lactate threshold or critical speed

 

Recovery Time for Repeats Above Lactate Threshold or Critical Speed

When running speed exceeds the lactate threshold (MLSS) or critical speed (CS), your body is in a state of metabolic instability (e.g., oxygen uptake gradually increases to VO2 max, heart rate gradually rises to max heart rate, and blood lactate steadily rises).

In these exercises, the role of recovery intervals is to allow these metrics to return to a baseline so you can repeat the exercise without reaching exhaustion.

The critical speed model is a useful conceptual tool; it suggests that running above critical speed consumes limited “anaerobic” energy reserves. Once these reserves are depleted, you will be too fatigued to continue. For example, running continuously at a 5K pace for 5 kilometers will deplete your anaerobic energy reserves from 100% to 0%.

 

 

Now, if you divide the same amount of running into 5 x 1000m with N seconds of recovery, the difficulty of the exercise depends entirely on the duration and intensity of N.

The length of recovery intervals follows an exponential decay process with a half-life. Recovery happens quickly in the first 10 seconds and then slows down.

For example, the intramuscular phosphocreatine (PCr) levels, an excellent indicator of anaerobic energy dependence, show that recovery occurs quickly in the early stages and then slows down.

When conducting high-intensity 300-meter repeats at 1500m pace, a recovery time of three times the repeat length is necessary. However, this recovery speed varies with an individual’s ability.

 

Recovery Time for Repeats at or Below MLSS

When engaging in high-intensity aerobic exercise (e.g., CS-, half-marathon pace, or marathon pace runs), during recovery intervals, you can choose between two goals:

1. Clear residual metabolic by-products to prevent rapid lactate accumulation
2. Stress the body to improve its ability to convert lactate into an energy source, a process known as lactate oxidation

These are very different goals and therefore require different strategies for recovery interval lengths.

1. Maintaining Control in High-Intensity Aerobic Training

For classic Daniels’ cruise intervals (e.g., 10 x 3 minutes at T pace), it’s possible to briefly exceed lactate intensity during the repeats. Short rest intervals can help clear metabolic by-products and bring the metabolic state back below MLSS.

In this case, due to the short half-life of the exponential decay function of recovery intervals, 1 minute of recovery time is sufficient for runners in good condition. Stronger runners might reduce this time to 45 or even 30 seconds without much trouble. Even for relatively long T pace repeats (e.g., 3 x 10 minutes at T pace), only 2-3 minutes of recovery is typically needed.

2. Increasing Muscle Lactate Oxidation

For half-marathon and marathon runners, advanced techniques involve using fast recovery intervals to put the body in a physiological state where lactate produced can be used as an aerobic energy source.

This requires two conditions:

1. Increased lactate production in fast muscle fibers
2. High carbohydrate oxidation rate capacity in slow muscle fibers

This can be achieved by alternating between fast but fully aerobic pace repeats (e.g., marathon or half-marathon pace) and “recovery” intervals that are still quite fast—only 10-15% slower than the repeats.

This fast recovery is necessary to create a favorable metabolic condition for lactate transport and oxidation during high-intensity activity. Therefore, recovery intervals should not be too slow to burn significant amounts of lactate during the intervals.

This is why top marathon and half-marathon runners use “alternating pace training,” such as 10 x 1k (105% MP) / 1k (90% MP).

Completing a kilometer at a fast recovery pace allows them to spend more time in a state of high lactate transport and oxidation, thus gaining greater training stimulus for these abilities.

 

What to Do During Recovery?

Four options: standing, walking, jogging, or fast running, with speeds ranging from very easy running pace to quite fast recovery intensity.

1. Standing Recovery
   Most coaches do not recommend complete standing still. Being completely still for more than thirty seconds is inadvisable. Walking takes advantage of the “muscle pump action” to maintain blood flow, which standing lacks.
2. Walking Recovery
   Walking recovery is used when you want to recover quickly without gaining any additional benefits. For example, 6 x 300m at 100% 1500m pace with 4 minutes of walking recovery.
3. Jogging Recovery
   For healthy runners, jogging won’t significantly hinder recovery.

Example: 4x1600m at T pace with 1 minute and 30 seconds of jogging recovery. At T pace, lactate accumulation doesn’t exceed the threshold, making the recovery half-life short enough that 1 minute and 30 seconds of jogging is sufficient.

4. Running Recovery: Easy, Moderate, Fast
   To understand the impact of intensity during recovery intervals, refer to the illustration showing black and white circles representing different recovery intensities.

Notice that resting recovery is faster than continuing exercise. Black circles represent true rest (sitting on a bike), showing that:

1. Recovery is slower
2. Recovery values drop below the baseline

The speed of recovery isn’t depicted, but it’s faster initially and slows down later, with lower overall anaerobic capacity regeneration at higher recovery intensities.

 

Using Easy, Moderate, and Fast Running Recovery

Incorporate low-load Fartlek-style accelerations in normal easy runs to help your legs feel stronger for the next day’s training.

Example:

• 60 minutes easy run: The entire session lasts 60 minutes, mostly at an easy pace.
• 30 minutes acceleration run: Within the 60 minutes, spend 30 minutes alternating accelerations.
• 30 seconds fast run: Accelerations are 30-second fast runs at around 5K pace.
• Every 2 minutes and 30 seconds: Each fast run is followed by 2 minutes and 30 seconds of easy pace recovery.

This method integrates short bursts of high intensity within a long easy run, enhancing training efficiency while avoiding overtraining. It’s suitable for runners who want to maintain aerobic base while adding some anaerobic endurance.

Example:

• 8km easy run + 3 sets (2.4km at 101-103% marathon pace, 800m easy to moderate recovery)

Running 7.2km directly at 103% marathon pace might be challenging, but running 2.4km intervals below T pace (around 106% MP) shouldn’t significantly tax your anaerobic reserves. Easy to moderate recovery prevents 2.4km repeats from being too fast.

For half/full marathon runners, this can serve as a foundation for more structured training with quick recovery intervals.

 

Fast Recovery Intervals

Fast recovery intervals are beneficial for elite runners to break through training plateaus. Proper pacing skills are crucial to execute such training correctly. Overtraining by running repeats too fast or recovering too quickly can be counterproductive.

Previously discussed principles of fast recovery intervals create a metabolic state in muscles favorable for lactate oxidation. Running intervals at or slightly below MLSS for long distances (e.g., 1km at T pace or 2-3km at marathon pace) elevates blood and muscle lactate levels.

High-intensity recovery during intervals helps the body transport and oxidize lactate for energy.

Example:

• 8 sets (1km at 105% MP, 1km at 90% MP)

Such training can evolve in three directions:

• Higher training volume (e.g., 10 x 1k / 1k)
• Greater stretch (e.g., 5 x 2k / 1k)
• Faster recovery pace (e.g., 8 sets of 1km at 105% MP, 1km at 95% MP)

 

 

Summary

Most of the time, using time-based recovery is optimal. Distance-based recovery is useful for team training or when you want more flexibility to adjust recovery by feel.

After repeats faster than MLSS, the goal during recovery intervals is to regenerate some of the anaerobic energy consumed.

For repeats at or below MLSS, the two goals are either to prevent repeats from being too fast or to mobilize the body’s lactate transport and oxidation mechanisms.

In the first case, short slow jogs are best. In the latter, you should run faster for longer (about 3-4 minutes) at 5-15% slower than MLSS.

Recovery is an exponential decay process with a half-life, so it starts very quickly and then slows down. Short recovery for moderate-intensity repeats and longer recovery for very fast sprints or extended moderate repeats are needed.

Recovery speed depends on your aerobic capacity. For sub-2:50 marathoners, fast recovery intervals below MLSS mobilize lactate oxidation as fuel, a particularly useful skill. This is why top marathoners use recovery intervals only 5-15% slower than their repeats in MP and HMP training, a secret to elite marathon training.

Katsuo Stamina was developed with these in mind?
• To speed up the breakdown of lactic acid
• To improve endurance
• To prevent muscle damage
• To shorten muscle recovery time

How do one use with the correct dosing of Katsuo Stamina during an activity?

Primarily once we begin our workout, Lactic Acid is formed and over time it will sore our muscles (a natural body reaction) to communicate to our brain that we need to slow down. That’s basically is our body’s own defence mechanism.
Katsuo Stamina helps by flushing out the lactic acid present and also to convert the remaining into energy thereby allowing us to feel lighter with our muscles and continue at the pace/speed where we are going at.

The picture illustration show’s the recommended dosage of using Katsuo Stamina. It is important to note that as with all activities, the recommended to “How to use Katsuo Stamina” begins with a single dosage (in this case 3 tablets, 30 minutes before the start of the activity.
Some consumers often question the need to consume this single dose before the activity and wonder why. When we begin our activity, even before our body could feel the effects of the onset of Lactid Acid, well into 20 minutes, our body will start to have accumulation of Lactid Acid. Although Katsuo Stamina tablets are manufactured for easy absorption, it is therefore advisable to consume them 30 minutes before the start of the activity to cover for the entire duration of the activity .

Following the illustrated chart, the next dosage is to be followed accordingly.

Road Running
• Half Marathon – A single dose (3 tablets) before start
• Full Marathon – 2 doses (6 tablets) before start AND/OR A single dose (3 tablets) before start with midway the 2nd dose (3 tablets)
• Ultra Marathon – 2 doses (6 tablets) before start with 1 dose (3 tablets) every other 20km into the activity.

Trail Running
• Trail Run (less than 15km) – A single dose (3 tablets) before start
• Trail Run (15km to 30km) – 2 doses (6 tablets) before start AND/OR A single dose (3 tablets) before start with midway the 2nd dose (3 tablets)
• Trail Run (above 30km) – 2 doses (6 tablets) before start with 1 dose (3 tablets) every other 15km into the activity.

42.195公里的馬拉松是一場挑戰人類極限的運動，能否順利完賽，不僅取決於平時科學的系統性訓練，還考驗著賽日當天的狀態，而有效的補給在狀態發揮上則充當了非常重要的角色，
補給不全面或不及時，輕則影響比賽表現，重則危及生命安全。

因此馬拉松途中會設置不同的補給點向跑者提供各式各樣的補給品，如果按照補給目的來分，大致可分為以下幾類：

一、補充糖原
糖原是身體能量的重要來源，跑馬過程會大量消耗肌肉中糖原含量，使體能下降。適量且及時補充糖原有助於維持人體血糖水準平衡，縮短體能恢復的時間。CP點用於補充糖類的食物很多，除了常見的米飯、麵條、饅頭等富含碳水化合物的食物，還有能量膠和能量棒這樣的快速補充糖類的運動營養補給品。

二、補充水
成年人體內約70%的成分是由水組成，水分以汗液的形式排出，對人體散熱、體溫調節產生影響。運動過程中缺水容易出現口乾舌燥、氣短的感覺，及時補水確實是非常有必要的。

三、補充電解質
汗液排出除了帶走水分，還會帶走大量含鈉、鉀、鎂、鈣等元素的電解質，這些微量元素的失衡會造成跑者疲勞，頭痛、噁心以及抽筋，像鹽丸、各種功能性飲料含有鉀鈉鈣鎂等微量元素，正好滿足跑者的需要。此外一些水果（例如香蕉），富含鈉、鉀、鎂等多種礦物質也是補給品中的座上客。

除了糖類、水和電解質，有種物質很容易被人忽視，那就是蛋白質。蛋白質作為肌肉組織的重要成分，經歷馬拉松這樣的高強度運動後，人體的肌肉會有不同程度的損傷，更需要攝入蛋白質修復損傷的肌肉細胞和生成新的肌肉細胞，預防傷痛，增強力量。

但是從食物中獲取的蛋白質會面臨消化難、吸收慢的尷尬境地，這時補充肌鰹強蛋白質賽中補給包（簡稱“賽中包”）就能幫到你解決這些難題。

賽中包的乳清蛋白含量高，乳清蛋白屬於動物蛋白的一種。對比植物蛋白，乳清蛋白
是一類非常優質的蛋白，含有人體所需的所有必須氨基酸，就像母乳一樣，非常好吸收，是蛋白類的“精品”。

 

肌鰹強賽中包添加支鏈氨基酸（BCAA），對防止肌肉損傷、防止肌肉流失，增加肌肉力量有很好的效果。因為氨基酸屬於小分子蛋白質，和通過腸道消化再吸收的方式不同，小分子蛋白能夠直接被小腸壁吸收，吸收更快更徹底，對受損肌肉細胞修復和對抗身體疲勞效果更明顯。

除了支鏈氨基酸（BCAA），賽中包還特別添加膠原蛋白，膠原蛋白被人體吸收之後到達軟骨組織，修復關節軟骨和肌腱，就像“潤滑劑”一樣，改善激烈運動帶來的關節脹痛和僵硬感。

對於有乳糖不耐受症的跑者人群，他們對補給品的選擇有一定顧慮，肌鰹強賽中包也貼心地考慮到這一點。乳糖不耐受症是由於人體乳糖酶分泌少，導致不能完全消化乳糖引起的非感染性腹瀉。肌鰹強賽中包不含乳糖成分，跑者可放心食用~

下次去跑馬，除了補給糖、水和電解質，記得帶上肌鰹強賽中包，輕鬆補充蛋白質，為肌肉運動再加點力量！

過去的肌肉疲勞理論認為，乳酸是造成肌肉疲勞、限制運動表現的直接原因。但是隨著更多研究問世，這些關於乳酸的理論假說被推翻，人們似乎開始走向另外一種極端：乳酸和肌肉疲勞毫無關係，事實真的是這樣嗎？
 

我們先來看看什麼是乳酸？

介紹乳酸之前，我們需要先了解ATP和人體供能方式這些概念。

ATP（又名三磷酸腺苷），是人體活動的能量來源。我們人體的供能方式有三種：磷酸原供能、糖酵解供能和有氧供能，雖然三種供能方式不同，產能有效程度不同，但最終目的是一樣的，就是生產ATP來為人體提供能量。

而乳酸就是從糖酵解供能方式來的，是糖原（人體供能原料）燃燒不充分的代謝物。乳酸對應的英文名稱有兩個：Lactic acid或者Lactate。中文翻譯雖然一樣，實際卻是兩種不同的物質，Lactic acid是一種弱酸，能夠被人體迅速分離成氫離子。Lactic acid被分解後，剩餘的部分會和鈉離子（Na+）或鉀離子（K+）結合，形成乳酸鹽（Lactate）。

肌肉中和血液中不會存在太多的Lactic acid和Lactate，這得歸功於乳酸脫氫酶（Lactate dehydrogenase）這種物質，使得乳酸的含量始終保持一個相對平衡的狀態。
 
 

乳酸是怎麼產生的？

上面講到，乳酸主要來自於糖酵解供能方式，那具體是怎麼產生的？

一般情況下，人體運動強度不大，身體通過消耗氧氣使糖原得到充分燃燒，產生大量能量，這時身體的供能方式為有氧供能。如果運動強度在短時間內迅速增大，有氧供能的效率不能滿足身體需要，身體就會轉入糖酵解供能方式，糖原燃燒不充分，只能生成少量能量 + 大量乳酸。（過程如下圖所示）

 

實際上，人體無時無刻都會產生乳酸，像日常走路、洗碗、搭公交等行為都會產生乳酸，之所以乳酸數量保持相對穩定，秘密就在於人體本身就有足夠的乳酸脫氫酶將其分解掉。

隨著運動強度增大，乳酸生成速度越來越快，乳酸脫氫酶數量和分解速度不足以應付，乳酸會越積越多。想要快速分解乳酸，意味著需要更多的乳酸脫氫酶，或者額外的物質來誘導身體產生更多乳酸脫氫酶。

此外，日常我們進行大量運動，如跑馬拉松，出汗較多後服用鹽丸來補充身體流失的微量元素，這也與乳酸鹽有一定的關係。乳酸鹽（Lactate）的形成會消耗大量的鈉離子（Na+）或鉀離子（K+），這時身體需要攝入鹽丸等補給品來補充相應的微量元素。
 
 

乳酸和身體疲勞有什麼關係？

在了解乳酸和疲勞的關係之前，還需要了解乳酸閾值（Lactate threshold）這個概念。人體血液裏乳酸濃度隨著運動強度的增大逐漸上升，前期處於較為平穩增長的趨勢，當到達了某個點，血乳酸濃度由原來的平穩增長變為急速增長，這個轉捩點就是乳酸閾值，單位為mmol/L（毫摩爾/每升），代表身體由有氧供能為主轉入無氧供能為主。

每個人乳酸閾值都不同，總體來說專業運動員的乳酸閾值會比普通人的要高。這意味著什麼呢？意味著運動員和普通人進行同等強度的運動，運動員不會累得那麼快，能堅持更久，耐力更強，乳酸閾值的高低代表著人體清除乳酸的效率能力。運動員主要是通過進行有效的運動訓練產生大量乳酸，提升乳酸脫氫酶清除乳酸能力。所以乳酸閾值相對高，代表清除乳酸的能力越好，人在運動後不會輕易感到疲勞。

 

乳酸是不是一無是處？

當然不是。乳酸雖然是無氧代謝的產物、会影响运动表现，但是如果有足夠過的乳酸脫氫酶將其進行分解，它就可以變成丙酮酸，消耗氧氣得到充分利用，重新變成供人體使用的能量。因此乳酸利用得好，依舊是運動者的好朋友。

 
 

这里要注意了，服用肌鲣强后不仅减少了你体内的乳酸堆积，还能促进乳酸转化成能量，为你持续供能，提升你的耐力。

 
 

肌鲣强处理乳酸的作用机理是其所含鲣鱼蛋白肽可以刺激人体合成更多乳酸脱氢酶。研究证明，人体内的乳酸脱氢酶（Lactate dehydrogenase, LDH）能催化血液中的乳酸转化成丙酮酸（一种能量物质），乳酸堆积减少，身体疲劳感自然下降。

“与天斗与地斗与乳酸斗，其乐无穷。”

“我也曾努力想要PB，无奈我撞墙了腿都迈不动啊！”

“跑马拉松的人，不是在抗击乳酸，就是在乳酸堆积的路上。”

……

确实，乳酸这个家伙，一直困扰着爱运动的你。当运动强度上去了，它就如同鬼魅般如影随形，让你疲劳，让你难受。事实上，有没有一些方法能优美地KO它，让你的运动变得相对轻松呢？

 

今天，我们就一起来探讨下。

首先，我们来看看乳酸是如何产生的。

其实，人在运动的时候，体内的糖原会通过“燃烧”变为能量。分“有氧燃烧”、“有氧无氧混合燃烧”、“无氧燃烧”三种方式。充分燃烧的糖原变成了水和能量，没有充分燃烧的糖原，产生的”废物“便是乳酸。

当运动强度比较低时，你的身体主要处于“有氧燃烧”状态，大部分糖原彻底“燃烧”变为了水和能量，其产生的乳酸极少到能忽略不计。

随着运动强度的逐渐提升，你的身体变为“有氧供能”与“无氧供能”叠加状态为主，乳酸从这一刻开始增量。糖原的一部分变成了能量，一部分变成了乳酸。

当运动强度比较高时，你的身体已经变为“无氧供能”为主，糖原的一小部分变成了能量，大部分变成了乳酸。从而造成乳酸的堆积加快，体内乳酸含量越来越高。

 

你的脚步越发沉重，真的是乳酸在作怪吗？

表面上看，乳酸堆积导致肌肉疲劳感的产生，让人丧失继续运动的能力，不得不终止运动，你停下来——身体自我保护的目的达到了。这似乎就是为什么你在30km左右撞墙期死活跑不动的原因。

实际上，肌肉疲乏感是氢离子集结的结果。每当你的身体里产生一个乳酸分子，就有一个氢离子形成。氢离子会降低血液的pH值，使肌肉呈酸性，而酸性会刺激肌肉神经末端，造成疼痛、沉重、灼热等不适感，让人误以为是乳酸的缘故。

不过，停下来的过程中，乳酸被分解了，你似乎又获得了能量，又能继续跑下去了。

 

慢着，乳酸分解还能提供能量？

是的，你没听错。

科普时间——

乳酸经过转化变成丙酮酸后，在肌肉的线粒体里被“燃烧”释放出大量的能量，提供运动所需的力量。

丙酮酸什么的听起来是不是十分拗口？简单来说，你可以想象身体如同一根木柴。柴燃烧的时候呢，可能有两种情况。一是完全燃烧化成灰热量耗尽，二是没有完全燃烧变成炭，炭是可以继续燃烧释放热量的。同理，乳酸就好比未完全燃烧的炭，是一种可被再次利用的燃料。

懂了吧？

传统的方法是如何处理的？

一般为服用乳酸药丸。先来看看，药丸的成分大多为：维生素+乳酸钙、镁。它的作用机理按商家描述的应该是——血乳酸达到一定浓度就会刺激神经反射，减少细胞内乳酸生成，延缓疲劳，增强耐力。简单来说就是，我先让你摄入一定量的乳酸，事先提高血乳酸水平，从而抑制细胞内乳酸的生成。

存在则合理，我相信这个方法肯定是有效的。

但是，不少跑友存在疑问。

当血乳酸达到一定浓度后，细胞内的乳酸产量虽然变少了，但它还在不断增加不是吗？事先摄入乳酸不会加重身体的负担啊？有没有方法能把堆积的乳酸分解掉？不仅能把乳酸处理掉，还能获取其中的能量，效果岂不是更佳？

有，当然有。

肌鲣强是如何处理的？

先来看看肌鲣强的主要成分：鲣鱼蛋白肽。

科普时间——

猎豹是陆地上速度最快的哺乳类动物，其极速奔跑速度是100公里/小时，但只能坚持15秒，多则可能导致其身体过热而死亡！相比猎豹，鲣鱼能在水里以90公里/小时的速度持续暴走2小时，并保持正常的生存状态。

科学研究表明，鲣鱼体内富含鲣鱼蛋白肽，因为这种物质的存在，鲣鱼能迅速分解体内堆积的乳酸，为身体持续供能，运动起来自然像开了挂一般。肌鲣强里的主要成分鲣鱼蛋白肽就是从鲣鱼体内提取的。

肌鲣强处理乳酸的作用机理是其所含鲣鱼蛋白肽可以刺激人体合成更多乳酸脱氢酶。研究证明，人体内的乳酸脱氢酶（Lactate dehydrogenase, LDH）能催化血液中的乳酸转化成丙酮酸（一种能量物质），乳酸堆积减少，身体疲劳感自然下降。

这里要注意了，服用肌鲣强后不仅减少了你体内的乳酸堆积，还能促进乳酸转化成能量，为你持续供能，提升你的耐力。

 

其实，肌鲣强还能给你额外的好处。

它能让你减免损伤——

人体过量运动时，细胞内的ＣＫ值（磷酸肌酸激酶）激增。达到一定的程度的时候，ＣＫ会溶解细胞膜，造成肌肉损伤。跑马拉松的你应该深有体会。那些跑后腰酸背痛这里伤那里伤（延迟性肌肉疼痛），其实都不是乳酸在作怪，本质都是细胞损伤。肌鲣强可以明显降低肌细胞的CK水平，减少肌肉拉伤，让你在赛后免于疼痛之苦。

它能加速你的恢复——

大量使用报告显示，服用肌鲣强可以快速恢复体能。标准马拉松通常第二天就恢复正常情况的80~90%。超长距离、多日比赛，每天保持较低的疲劳状态，次日早晨恢复到正常情况的80%左右，赛后恢复期不超过2天。

说到这里，我们还是看看专家怎么说吧。

东京大学院研究运动生理学的“乳酸”教授八田秀雄(Hideo Hatta) 先生，专注研究乳酸和相关的知识一辈子，每年二月召开一次全球“乳酸大会”。

在日本著名运动杂志《Run + Trail》上最新发布的“乳酸分解力”实验中，八田让五位来自东京地区的专业跑步教练分别在服用肌鲣强和不服用肌鲣强的情况下，分7次每次3分钟，测试在提升运动强度的条件下，乳酸的浓度变化。

 

以下实验在日本东京横滨市运动医学科学中心进行。

数据显示：

1、在同等的运动强度下，服用组血中乳酸浓度明显更低。

2、在同等的血中乳酸浓度下，服用组能达到更高的运动强度。

实验证明，肌鲣强可以有效地分解运动中堆积的乳酸，降低血中乳酸浓度，提高运动持久力。

还有一项对比数据值得关注。

数据显示：

随着运动强度的提升，差值越来越大（非线性）。

这说明了，当你的运动强度越大，服用肌鲣强的效果就越显著。

 

这会你总算明白了吧？

肌鲣强不仅能优雅地搞定乳酸堆积，还能促进乳酸分解提供能量，提升耐力，减免你的肌肉损伤，加速你的恢复。

跑步是一项痛并快乐着的运动，如果一定要列举跑步的几大痛苦，那么“乳酸之苦”一定名列前茅。高强度的间歇跑、变速跑，以及马拉松比赛中后程时，那种肌肉僵硬、酸麻、沉重、发不上力的感觉，就是乳酸造成的。

乳酸这个家伙，一直困扰着爱跑步的你。当运动强度上去了，它就如同鬼魅般如影随形，让你疲劳难熬，酸痛难受。

其实，这是正常现象，却大大影响了跑友的心情，尤其是对于刚刚入坑的跑友而言，它往往是坚持不了跑步的原因之一——稍微跑个步，不仅会累，还会腿疼屁股疼。

“知己知彼，百战不殆”，先来了解乳酸的来龙去脉。

我们知道，人体主要有三种供能系统，分别是有ATP-磷酸肌酸供能系统、有氧供能系统和无氧供能系统。ATP在肌肉中含量低，供能时间非常短，只有1~3秒，此过程非常迅速。所以这里我们重点说有氧供能和无氧供能。

人在运动的时候，体内的糖原会通过“燃烧”变成能量。这个“燃烧”的过程分为两种方式，分别是“有氧燃烧”以及“无氧燃烧”。充分燃烧的糖原变成了水和能量，而燃烧不充分的糖原，就会转变为“废物”——乳酸。

那么，怎么才能确定乳酸的产生情况呢？具体可以看运动强度！

1、运动强度较低时，比如慢跑，身体为有氧供能系统发挥主要作用，就处于“有氧燃烧”的状态，体内大部分糖原彻底“燃烧”变成水和能量，产生的乳酸极少到忽略不计。

2、随着运动强度的逐渐提升，有氧供能系统不能满足运动员需要时，无氧供能系统随即被启动。这时候，你的身体变为“有氧供能”与“无氧供能”叠加状态为主，乳酸从这一刻开始递增。糖原的一部分变成了能量，一部分变成了乳酸。

3、当运动强度较高时，你的身体已经变为“无氧供能”为主，身体进入无氧运动状态，氧供能不足的情况下，糖原燃烧不充分，一小部分转变为能量，大部分转变为乳酸。乳酸堆积加快，体内乳酸含量越来越高，它会让人感到肌肉酸痛，抽筋，甚至是丧失运动能力……

乳酸这种东西，人体里都有。比如，平时做个家务、买个菜、逛个街，帮老婆拎个包，日常挤个地铁 ……只要有动作，也产生乳酸。只是，在这些活动过程中，人体有能力对它进行分解，所以，你没啥感觉！

一旦你开始做运动，尤其是运动负荷达到一定强度时，超过乳酸阈值后，人体的疲劳感就会暴增，耐力直线下降，双腿就像是灌了铅一样乏力沉重，难以继续前行，严重者可能会导致抽筋的发生……

乳酸阈值——在运动过程中，人体血液内的乳酸浓度会随着运动负荷的渐增而增加。当运动的强度到达某一负荷时，血液内的乳酸浓度就会急剧上升，这一临界点就称为乳酸阈值。

 

其实，我们可以把乳酸堆积看作人体的一种运动保护机制，限制你的运动强度，以免机体崩溃造成严重后果。我们应该庆幸有乳酸堆积这种设定，并赞叹大自然的神作。

只不过，跑步时遭遇乳酸堆积真的很难受。

对抗乳酸，这3招get一下！

1、控制比赛配速，提倡先慢后快。

先慢后快的好处是，起跑阶段较慢的配速下，产生的乳酸较少，即便后程加速产生大量乳酸，但那时比赛已经快结束了，所以忍受“乳酸之苦”的总时间并不多。另外，起跑后经过一段时间的“预热”，人体肌肉的温度升高、粘滞性降低、血流量增加，才可以承受更高强度的运动，这也有利于后程的加速冲刺。

相反，当你一开始冲得太快，乳酸堆积过多，意味着接下来大部分赛程都要和乳酸抗争，整个过程比较痛苦，而总成绩不见得提高（后程一定会掉速），可谓得不偿失。

建议无论全马、半马比赛，前2-3公里比正常配速慢5-10秒/公里为宜，前半程最好不要超过目标成绩的平均速度。而且，业余跑友参加马拉松往往没有地方做热身，所以前2-3公里降低一点配速当做“预热”更是必要的。

2、日常训练提高乳酸分解能力。

“乳酸阈值”所处的运动强度越高，你就可以在更快的配速下不增加乳酸堆积。根据最新的研究表明，提高乳酸阈值，最重要的是增加身体分解乳酸的能力。

换句话，从本质上来说，想要提高乳酸分解能力，那么提高有氧能力才是王道（而不是无氧）。而高水平的有氧能力，需要通过各种手段多管齐下来训练：LT训练通常会分为两种：间歇跑和节奏跑。两者的差别在于前者是以间歇的方式进行，比较适合初学者；后者则会持续跑一段时间，执行难度相对比较高。

（1）间歇跑：短时间多次数、配合短的休息时间进行，比如快跑距离从800到3200米，恢复从30到60秒不等。显然这个距离越长，恢复时间越短，难度越大。

（2）节奏跑：做好充分热身，慢慢加速，然后一直按乳酸门槛速度跑下去，根据自身状态5-20分钟，再慢慢减速，最后放松拉伸。节奏跑通常建议持续20分钟以上，对训练乳酸阈值的效果更佳。刚开始不适应可以逐渐增加时间，避免受伤。

最后，一定要注意这样的训练一周不要超过两次，训练之间最好间隔两天进行恢复性训练或休息，同时一种训练方法即使再有效，但如果总是一成不变，那么也太不可能达到理想的训练效果。

3、使用排酸黑科技加速乳酸分解。

事实上，乳酸分解后也是可以提供能量的，人体在分解乳酸时需要乳酸脱氢酶作为催化剂。但人体的乳酸脱氢酶合成有限，当乳酸产生的速度大于其分解（乳酸脱氢酶催化乳酸分解）速度时，身体会越来越疲累，肌肉越来越酸痛。

肌鲣强处理乳酸的作用机理是其所含鲣鱼蛋白肽可以刺激人体合成更多乳酸脱氢酶。研究证明，人体内的乳酸脱氢酶（Lactate dehydrogenase, LDH）能催化血液中的乳酸转化成丙酮酸（一种能量物质），乳酸堆积减少，身体疲劳感自然下降。

这里要注意了，服用肌鲣强后不仅能减少你体内的乳酸堆积，还能促进乳酸转化成能量，为你持续供能，提升你的耐力。

而且，肌鲣强可以明显降低肌细胞的CK水平，减少肌肉拉伤，缓解赛后24-48小时内产生的延迟性肌肉疼痛，并能加速你在赛后的体能恢复。

 

你还在等什么？

用上这3招，快乐地跑起来吧！
