我們將以簡單術語談低密度脂蛋白(LDL),它實際上不是膽固醇,它是蛋白質載體,蛋白質不能很好地與水混合,因此需要轉運載體。但是,LDL確實含有膽固醇。 人們認為LDL不好,是因為LDL將膽固醇帶入動脈,高密度脂蛋白(HDL)然後將膽固醇從動脈中運送肝臟。體內的每個細胞都會產生膽固醇。 實際上,身體每天會產生約3,000 mg的膽固醇。您需要它來生存。LDL直接綁住並減滅細菌毒素,以防止對身體傷害,它甚至可以幫助您治癒細胞。 導致LDL過高主要原因是: 1.高胰島素,糖尿病前期和糖尿病 2.甲狀腺功能減退 3.感染 4.腸道滲漏 5.遺傳 6.壓力 7.手術 8.內臟脂肪

不要只降低LDL,要找出導致LDL過高原因?您有上面提到的問題之一?在減少飲食中的所有膽固醇之前,請先解決這八個問題. 柏格醫生簡介: 柏格醫生現年55歲,是脊椎醫生,專門研究健康生酮和間歇性斷食。 他是暢銷書《健康生酮飲食》的作者,也是Dr. Berg’s Nutritionals營養品總監。 他不再執業,而是專注於社交媒體教育健康知識。 柏格醫生購物商店 : http://www.drberg.com/blog 柏格醫生的臉書: fb.me/DrEricBerg

Book reading: Elasticsearch The definitive guide - A distributed real-time search and analytics engine

Oct. 1, 2021

Introduction

I spent a day to read the book called Elasticsearch The definitive guide. I went over the book page by page, read something if I like, and then look for some good presentation through the book. 

My reading time | Highlights | What to do to be a better reader

I like to spend time to work on more reading related to the book. 

  1. Authors: Clinto Gormley & Zachary Tong.
  2. First few hours are very important. Once I understand the basics from the book, I will go back to read the book again and again. 
  3. I should become a best book reader in my early ages, for example, in my 20s, or in my 30s. 

Whether you need full-text search or real-time analytics of structured data or both—the Elasticsearch distributed search engine is an ideal way to put your data to work. This practical guide not only shows you how to search, analyze, and explore data with Elasticsearch, but also helps you deal with the complexities of human language, geolocation, and relationships.

If you’re a newcomer to both search and distributed systems, you’ll quickly learn how to integrate Elasticsearch into your application. More experienced users will pick up lots of advanced techniques. Throughout the book, you’ll follow a problem-based approach to learn why, when, and how to use Elasticsearch features.

  1. Understand how Elasticsearch interprets data in your documents    <- Focus on this part first
  2. Index and query your data to take advantage of search concepts such as relevance and word proximity
  3. Handle human language through the effective use of analyzers and queries
  4. Summarize and group data to show overall trends, with aggregations and analytics
  5. Use geo-points and geo-shapes—Elasticsearch’s approaches to geolocation
  6. Model your data to take advantage of Elasticsearch’s horizontal scalability
  7. Learn how to configure and monitor your cluster in production

8 Running Workouts to Build Strength and Endurance

Written by Doug Hay • Last Updated: March 11, 2021

When did running get so complicated?

I ask myself that all the time, usually when frustrated by a tough workout on my training plan or a confusing training concept.

Running is such a simple act

— exactly what drew me to it in the first place — until you complicate it with drills, exercises, workout nutrition, and complex workouts.

Of course, it probably comes as no surprise that the workouts on your training plan aren’t there to punish or frustrate you — they’re included to help you run stronger, faster, and for longer distances.

Plus, once you get to know them, they’re not so confusing, and can actually be a lot of fun.

So today I’m going to break down eight common running workouts, and share real-life examples I use with my coaching client. Plus, how they can fit within your week of training.

Don’t have time to dive in? Here’s what you need to know: When it comes to running, workouts get complicated quickly if you don’t know the theory behind them. Group workouts into three categories — easy, speed, and long run — and aim for at least one of each per week. Use tools like the Marathon Roadmap as a guide to better understanding your training.

The Importance of Variety

Before we start wading through the details, let’s first talk about variety. More specifically, why variety in your training is so important.

There’s a little running phenomenon I like to call “Single Speed Running,” where a runner logs nearly all of his or her miles at the exact same effort. Day after day. That speed is usually around 75 percent of max effort — not fast enough to really make your body work hard and adapt, but too fast to build much endurance or count as a “recovery” run.

Sound familiar?

Chances are it does, since that’s exactly what most runners do, whether they’re training for a marathon, 5K, or ultramarathon.

Not only does Single Speed Running keep you from getting stronger; it also significantly increases the risk of injury: our bodies need variety.

We need uber slow runs just as much as we need Lightning Bolt style sprints. The variety works the cardiovascular system and muscles in different ways, and makes room for both strength-building and recovery.

By understanding the importance of each workout, you’re more likely to begin incorporating a variety into your training, and in return, reaping the benefits.

But first, those workouts need to become less daunting and confusing … the goal of this post.

8 Common Running Workouts, Explained (With Examples)

Below you’ll find a description of eight common running workouts for endurance runners. With each explanation, I’ve also included examples for a variety of levels of how to put the workout to use.

Let’s start with the easiest:

1. The Easy Run

I’m putting the easy run first because it’s often the forgotten workout. But it’s also one of the most important.

Running at an easy pace builds endurance, promotes proper form, establishes routine and base mileage, and facilitates recovery. This type of run should be your most common, making up about 65-80% of your mileage (the percentage will vary depending your running philosophy).

The easy run is your aerobic workout, staying within heart-rate zones 1 and 2. If you’re unsure where that is for you, ask yourself this question when you’re running:

Can I keep a conversation going, speaking in paragraphs with full sentences?

Ask it out loud if you’re really unsure … just maybe not when others are within earshot.

If the answer is yes, you’re running in that aerobic, or easy zone, where your body and muscles have the energy and oxygen they need. For most runners, this is also where they should run the majority of their long run miles.

Sample Workouts

Beginner:

  1. Workout: 45 minutes at an easy pace. With this variation, distance doesn’t matter. You’re running for time instead of distance, so there’s no pressure to hit certain mileage.

Advanced:

  1. Workout: 6-10 miles at an easy, conversational pace. There should be no set structure or fluctuations in speed, but the hardest part will be resisting the temptation to speed up.
  2. Mid-week easy longer run: 10 miles at easy pace, positioned in the middle of the week between weekend long runs.

2. The Tempo Run

The tempo run’s pace is often called comfortably hard. Difficult enough to require pushing, but comfortable enough to where you can sustain the effort. This is often around 85-90% of your max heart-rate, or just a hair slower than your 10K race pace, where short sentences are possible, but a full-blown conversation isn’t.

If you’re unsure of your paces, check out this pace predictor. It isn’t perfect, but will give you a ballpark pace to aim for.

We run tempo workouts to increase our lactate threshold, or that point at which your body switches from its aerobic system to its anaerobic system, and quickly fatigues thereafter. The higher your threshold at a certain pace, the longer you can sustain that given pace and build strength, speed, and endurance.

Sample Workouts

Beginner:

  1. Workout: 40 minute run with 3 x 5 minutes at tempo pace, and a 3 minute recovery in between. For this style workout, you’ll start the 40-minute run with an easy warmup, once warm, begin five minute tempo intervals with three minutes of rest, and repeat three times. Allow for time at the end to cool down.

Advanced:

  1. Workout: 90 minute run with 3 x 15 minutes at tempo pace, and an 8 minute recovery in between. A workout like this, with longer tempo intervals, is great for marathon racing speed.
  2. Workout: 60 minute run with 3 x 8 minutes at a tempo pace, and a 4 minute recovery, include hills during tempo sections. Tempo workouts can also include hill training, which is particularly helpful while training for a hilly race.

3. The Progression Workout

A progression workout is one of my favorites, and commonly found in marathon training plans. The idea is simple:

Start slow, finish fast.

Over the course of your workout, you’ll increase in pace by starting easy and finishing hard.

This progression in pace gives you a complete workout, using both your aerobic and anaerobic systems, without over-straining your body or requiring the same recovery time as a traditional speed workout.

Sample Workouts

  1. Thirds Workout: 15 minutes at an easy pace, 15 minutes at a comfortably hard pace, 15 minutes at a hard pace. In this workout, you’ll increase speed at every 15 minute increment throughout the run, starting at an easy pace and making your way up to a hard pace.
  2. Fast Finish Workout: 45 minutes at a comfortably easy pace, 10 minutes at a hard pace, 5 minutes all out. Here you’re maintaining the easy pace throughout most of the run, until the final 15 minutes when you increase to hard and then all out. This a great option for mimicking a late race push.

4. The Hill Workout

Hill workouts are often referred to as “speedwork in disguise,” because they offer many of the same benefits of a traditional speed workout, without having to run at top speed.

Running uphill is all about building that explosive power that promotes speed and improved running economy.

Running downhill works your quads, and builds strength in your tendons and joints.

Both are important to a well-balanced runner, so I recommend incorporating uphill and downhill days into training for any sort of hilly course. Just focus your workout on one at a time to get the biggest benefit and reduce the risk of injury.

Hill workouts can be done through hard, short sprints up (or down) a hill, or by running a sustained, gradual hill.

Sample Workouts

Beginner and Advanced:

  1. Short Hill Sprints: 8 hill sprint repeats with light jog back down to rest, following a 3-mile easy run. This type of hill repeat will build explosive strength in the legs, and teach you how to attack shorter hills during a race.

Advanced:

  1. Sustained Hill Repeats: 5 x half-mile hill climbs on a gradual incline with easy run back down to rest. This is perfect when training for a hilly race, and builds endurance and strength on climbs and flats.
  2. Sustained Uphill / Downhill Repeats: The same 5 x half-mile climbs on a gradual incline only you’re also going hard on the descent, with 90-120 seconds of rest in between. Each interval then becomes a full mile.

5. The Interval Workout

When you picture the quintessential speed workout, you’re probably thinking of interval training. A set distance, repeated a set number of times, at a set pace. Usually with a short rest period in between. Interval distances can be anywhere from 100 meters to a mile or more. Most marathon training plans focus on distances of 400 meters or longer, but the details are left to the workout creator.

Warning: Don’t piss off your workout creator. Interval workouts will likely be your most painful runs, the ones that leave you doubled over and gasping for air.

Most intervals are designed to build speed and strength by working your anaerobic system, or lactate threshold running, and focus on shorter distances of a mile or less. They can be run on a track or along a set loop.

Sample Workouts

Beginner:

  1. Workout: 8 x 400 meters on the track with a 400 meter light jog in between. Try to maintain a consistent pace for each of the 400 meter intervals.

Advanced:

  1. Yasso 800s: 10 x 800 meters on the track, with a light jog for the same amount of time it took you to run each 800 in between. The classic “marathon predictor workout.” I don’t believe it’s great at predicting race times, but it’s certainly a solid speed and endurance building option (and very tough).
  2. Workout: 2 x 1,000 meters with 2 minute rest periods + 2 x 800 meters with 90 second rest periods + 2 x 400 meters on the track with 60 second rest periods. In this workout you’re decreasing in the length of each interval, but increasing in pace.
  3. Workout: 4 x 1,600m with 120 seconds recovery in between. This is an endurance building interval workout. Aim to maintain a consistent pace for each mile, or increase slightly in pace over each interval.

The Ladder Run

The Ladder Run is a popular form of interval workout which climbs up, down, or both up and down in distance with a short (often 90 seconds or a 400 meter jog) rest period in between each interval. It’s a fantastic way to challenge yourself and mix things up, with a variety of high-intensity running paces and distances, all in a single workout.

On a track, increase in distance to the “top” of the ladder, or the longest distance interval, before decreasing back down. If you’re just descending the ladder, increase in speed as you decrease in distance.

Sample Workouts

Advanced:

  1. Up and Down: 400 meters x 2, 800 meters x 2, 1,600 meters, 800 meters x 2, 400 meters x 2, with a 400 meter light jog in between each interval. This is an incredibly tough workout, which tests and builds both your endurance and leg speed.
  2. Down: 1,600 meters x 2, 1,200 meters x 2, 800 meters x 2, 400 meters x 2, with a 400 meter light jog in between each interval. As you decrease in distance, you’ll increase in pace.

7. The Fartlek Workout

Ah, the classic Fartlek run. If you’d like to make fun of the name, be sure to pair it with a Jack Daniels joke.

The word fartlek means speed-play in Swedish, and that’s exactly what the workout is. An opportunity to play around with different speeds and distances in a single workout. This was my favorite workout day when I ran cross country in high school, and not just because of the name.

In a sport that requires plenty of structure, the Fartlek run allows your creative juices to flow. The workout is simple as this:

Intermix fast running with slower running, and vary the pace and distance of each interval. It could be as flexible as randomly picking a street corner, tree, car, or lamp post to sprint to, or run at a tempo pace for three minutes, followed by an easy pace for four minutes, and a sprint for one minute, and so on. There are no rules, other than to have variety in your paces and distances.

Sample Workouts

Beginner:

  1. Unstructured: 5-mile run with the final 4 miles consisting of 4-6 Fartlek intervals. This is probably the most approachable workout in this entire post (other than an easy run), since you have the freedom to do as you please.
  2. Upticks: 45 minute easy run with the last 15 minutes consisting of 5-10 short upticks to a tempo effort. Each uptick should last 15-30 seconds in length.

Advanced:

  1. Structured: 1-mile warmup + 3 miles, including four to six 5-minute surges each followed by a 2- to 3-minute period of easy running + 1-mile cooldown. If you need a little more structure to stay on track, this will still allow for flexibly and play, but is defined by set intervals.

8. The Long Run Workout

Your weekly long run is arguably the most important run of the week. It’s your chance to build endurance, and learn how to handle increased mileage both mentally and physically.

But for most people, that’s where it ends. They view long runs as only an opportunity to go long, not fast. I believe strategically planned long runs throughout your training are a great opportunity to work on late race speed, mimic the final push on race day, and toughen your mind to push through the fatigue.

By adding a workout element to you long runs, you’re giving them more structure and added benefit.

Now a few quick rules I recommend:

  • Don’t run a long run workout every week, but instead begin to integrate them into your training once you’re already comfortable with the distance.
  • Limit your long run workout pace to below a tempo pace, preferable somewhere around your marathon race pace.
  • Practice your racing fuel strategy, taking in calories every 45-60 minutes. (For a whole-food workout fuel, check out Plant-Bites.)

During a long run workout, you’ll either increase from an easy pace to your marathon race pace, or alternate between the two.

Sample Workouts

Advanced:

  1. 1-2-3 Workout: After your warmup, run 1 mile at marathon pace followed my 1 mile easy, then 2 miles at marathon pace and 2 miles easy, 3 miles at marathon pace and 3 miles easy. Alternatively you can structure this with kilometers instead of miles.
  2. Countdown Long Run Workout: Take the difference between your easy pace and race pace and divide that by the number mileage of your run. Increase your pace or “count down” by that set increment each mile, so that by the end of the run you have steady increased your pace from easy to race pace.

Putting it all Together: What a Sample Training Week Actually Looks Like

Now that you’ve got the workouts down, let’s explore what a sample training week — which includes a number of these workouts — could look like. I say could, because training structure depends entirely on your distance and pace goals, skill level, and where you are with your training.

But let’s assume you’re training for a marathon, and roughly 10 weeks into a 16 week training plan. Here’s what your plan could look like:

  • Monday: Rest.
  • Tuesday: Tempo workout — 70 minute run with 3 x 15 minutes at tempo pace, and an 8 minute recovery in between.
  • Wednesday: Easy workout — 45 minutes at an easy pace.
  • Thursday: Track workout — 2 x 1,000 meters with 2 minute rest periods + 2 x 800 meters with 90 second rest periods + 2 x 400 meters on the track with 60 second rest periods.
  • Friday: Rest.
  • Saturday: Long run workout — A 17 mile countdown long run.
  • Sunday: Easy workout — 30-45 minutes at an easy pace.

As you can see, this schedule includes a lot o the variety mentioned above — both in distance, pace, and the types of workouts.

Challenge Yourself With New Workouts

Remember how we said variety was so important earlier?

Now’s your opportunity to take action. It’s easy to get caught up in a monotonous, comfortable rotation of just a few workouts and paces.

Mix it up. Try something new.

The variety just may increase your speed and strength, and reduce your risk of injury.

Which happens to be every runner’s dream come true.

Sweatlife: Say goodbye to cholesterol 5.7 > 5.1 | Harvard medical article

 

11 foods that lower cholesterol

Foods that make up a low cholesterol diet can help reduce high levels

Changing what foods you eat can lower your cholesterol and improve the armada of fats floating through your bloodstream. Adding foods that lower LDL, the harmful cholesterol-carrying particle that contributes to artery-clogging atherosclerosis, is the best way to achieve a low cholesterol diet.

Add these foods to lower LDL cholesterol

Different foods lower cholesterol in various ways. Some deliver soluble fiber, which binds cholesterol and its precursors in the digestive system and drags them out of the body before they get into circulation. Some give you polyunsaturated fats, which directly lower LDL. And some contain plant sterols and stanols, which block the body from absorbing cholesterol.

1. Oats. An easy first step to lowering your cholesterol is having a bowl of oatmeal or cold oat-based cereal like Cheerios for breakfast. It gives you 1 to 2 grams of soluble fiber. Add a banana or some strawberries for another half-gram. Current nutrition guidelines recommend getting 20 to 35 grams of fiber a day, with at least 5 to 10 grams coming from soluble fiber. (The average American gets about half that amount.)

2. Barley and other whole grains. Like oats and oat bran, barley and other whole grains can help lower the risk of heart disease, mainly via the soluble fiber they deliver.

3. Beans. Beans are especially rich in soluble fiber. They also take a while for the body to digest, meaning you feel full for longer after a meal. That's one reason beans are a useful food for folks trying to lose weight. With so many choices — from navy and kidney beans to lentils, garbanzos, black-eyed peas, and beyond — and so many ways to prepare them, beans are a very versatile food.

4. Eggplant and okra. These two low-calorie vegetables are good sources of soluble fiber.

5. Nuts. A bushel of studies shows that eating almonds, walnuts, peanuts, and other nuts is good for the heart. Eating 2 ounces of nuts a day can slightly lower LDL, on the order of 5%. Nuts have additional nutrients that protect the heart in other ways.

6. Vegetable oils. Using liquid vegetable oils such as canola, sunflower, safflower, and others in place of butter, lard, or shortening when cooking or at the table helps lower LDL.

7. Apples, grapes, strawberries, citrus fruits. These fruits are rich in pectin, a type of soluble fiber that lowers LDL.

8. Foods fortified with sterols and stanols. Sterols and stanols extracted from plants gum up the body's ability to absorb cholesterol from food. Companies are adding them to foods ranging from margarine and granola bars to orange juice and chocolate. They're also available as supplements. Getting 2 grams of plant sterols or stanols a day can lower LDL cholesterol by about 10%.

9. Soy. Eating soybeans and foods made from them, like tofu and soy milk, was once touted as a powerful way to lower cholesterol. Analyses show that the effect is more modest — consuming 25 grams of soy protein a day (10 ounces of tofu or 2 1/2 cups of soy milk) can lower LDL by 5% to 6%.

10. Fatty fish. Eating fish two or three times a week can lower LDL in two ways: by replacing meat, which has LDL-boosting saturated fats, and by delivering LDL-lowering omega-3 fats. Omega-3s reduce triglycerides in the bloodstream and also protect the heart by helping prevent the onset of abnormal heart rhythms.

11. Fiber supplements. Supplements offer the least appealing way to get soluble fiber. Two teaspoons a day of psyllium, which is found in Metamucil and other bulk-forming laxatives, provide about 4 grams of soluble fiber.

Putting together a low cholesterol diet

When it comes to investing money, experts recommend creating a portfolio of diverse investments instead of putting all your eggs in one basket. The same holds true for eating your way to lower cholesterol. Adding several foods to lower cholesterol in different ways should work better than focusing on one or two.

A largely vegetarian "dietary portfolio of cholesterol-lowering foods" substantially lowers LDL, triglycerides, and blood pressure. The key dietary components are plenty of fruits and vegetables, whole grains instead of highly refined ones, and protein mostly from plants. Add margarine enriched with plant sterols; oats, barley, psyllium, okra, and eggplant, all rich in soluble fiber; soy protein; and whole almonds.

Of course, shifting to a cholesterol-lowering diet takes more attention than popping a daily statin. It means expanding the variety of foods you usually put in your shopping cart and getting used to new textures and flavors. But it's a "natural" way to lower cholesterol, and it avoids the risk of muscle problems and other side effects that plague some people who take statins.

Just as important, a diet that is heavy on fruits, vegetables, beans, and nuts is good for the body in ways beyond lowering cholesterol. It keeps blood pressure in check. It helps arteries stay flexible and responsive. It's good for bones and digestive health, for vision and mental health.
