Should you run when you are sick?

We runners hate missing our workouts. More often than not we try to make-up a missed workout or do the next run even harder.

However there are days when we fall sick. This brings up a lot of questions.  Should I still train or attempt that race? Will I lose my fitness if I don’t run? Should I take some medication and continue with my run?

In many cases a serious runner would think of more reasons to run than not too. And sometimes a bad decision results in disaster.

A general rule followed in case of sickness is called the “neck rule”. Symptoms below the neck like chest cold, bronchial infection, body aches means you should avoid training. While a running nose, sneezing do not pose a significant risk. Of course a fever means no running at all.

RPE …

RATE OF PERCIEVED EXERTIONS….THE BEST METRIC ?
PHYSIOLOGY FIRST

RPE is the best subjective estimate of ongoing exercise across all population .
Instruments donot calculate ,decipher or guide as our brain does to all the sensory inputs it receives from musculoskeletal,gastrointestinal, endocrinal , respiratory and metabolic pathways . It measures the FEEL … A combination of what the above systems are going through with the central motor commands on the feedbacks .

It benefits recreational runners as it’s free,easy to follow and practice on the run without stopping .it cross checks with heart rate (HR ) when all of us calculate 220- age , a vague , theoretical formula which donot correlate well with age .
For those who doubt which they shouldn’t … A meta analysis of 64 studies show a strong correlation with physiological variables like HR ,lactate ,%vo2 Max .
It correlates the best with ventilation and respiratory rate , the most reliable reflection of aerobic exercise intensity .it can be used while progession of exercises, to monitor, to perform aerobic or resistance training efficiently .

RPE is a 20 category scale but 0- 10 is used . Also known as Borg scale .the popular talk test is pure physiology .
Though till date no perfect one scale exist to help endurance athletes

RPE in my opinion is better placed because
: the studies conducted had max number of participants.
:it has linear correlation with multiple physiological parameters
:not always can you measure HR
:runners on medication… Hormonal , anti diabetic or anti hypertensive alter metabolic and
Cardiovascular responses should follow RPE diligently.
:True MHR till date is not accurately defined , diminishes with age ,varies with intensity ,
Weather and terrain .

If RPE is higher and heart rate in training zone ………. You are overtraining

If RPE and HR are lower than usual training zone …….your adaptation are improving .

If RPE and HR are lower on increasing cadence ……. Your running economy is improving .

If RPE is oddly higher for training zone ……..your body is warning you to stop .

If RPE is less for the training zone …………….your body is ready to push-up efforts .
Devices fail here .

Runners with positive history of hypertension,coronary artery disease , smoker , type A personality ,overweight ,with work stress .etc
Follow RPE …. There is no conflict of interest with running devices .

Race strategy- Checklist to Help You Run a Faster Race

My 11 Point Checklist to Help You Run a Faster Race- Heath Matthews

Introduction

This article is a collection of points I have developed using my personal experience in both competitive and social running over the last 27 years. It is by no means exhaustive and I am sure your personal checklist may be different. I hope that by looking into my approach to a race you are able to gain something from it and perhaps add a point or two to your list and therefore run that little bit faster in your next race. As always I am always very keen to learn from others so if you have any suggestions or advice you would like to send to me please feel free to do so at heath(dot)matthews at yahoo.com.

1. Get plenty of Sleep

It’s really important to be in peak condition on race day. One of the best ways to ensure you are fully recovered is to sleep on it. The experts will say that about 8 hours of sleep a night is optimum for adults. In my experience that magical number is much more difficult to pin down. My favourite saying is that “bodies don’t read textbooks”. By this I mean that 8 hrs may be too much or too little for you as an individual. To figure out how much sleep you need you should start by sleeping for 3 nights in a row for the same number of hours. I would suggest starting at 9hrs and decreasing by 30mins every 3 nights. Do this until you start to feel noticeably more rejuvenated and refreshed in the morning. To complete your experiment keep reducing your sleep by 30 minutes every 3 nights until you feel rather tired and exhausted. If this is the case then you have figured out what amount of time you need to sleep. This is not an exact number but more of a bandwidth of time. An example is that you may find that 6.5 to 7.5hrs is enough for you. More or less may make you feel a like tired and sleepy.

2. Wake up with enough time to wake up!

Your body needs time to wake up and get ready to exercise. Give it time to digest your pre-race meal, go to the toilet and loosen up prior to the race.

3. Pre-Race Meal

It’s important to eat the right food prior to your race. DO NOT do anything new in the 3 days prior to the race!!! It’s important to experiment and find what works best for you both during training and racing but this must be done weeks prior to the big day! Do not shoot yourself in the foot eating something that doesn’t agree with your digestive system just because you’ve been told that it’s good for carbo-loading.

Try to eat medium to high glycaemic index foods in the three days prior to the race. Again, nothing new in your diet just more frequent eating of the high energy foods.

On race day you should eat a light and easy to digest prerace meal. Don’t panic and try to cram extra energy into your body. Chances are excessive food and liquid will just bloat you and cause discomfort in your bowel during the race. Often it will cause a cramp or stitch which can be disastrous to your race as you would need to slow right down to let it settle.

I often will have mostly liquids with fruit and sweets. These foods are easy to digest, high on the glycaemic index and I know they won’t make me bloated or uncomfortable.

4. Warm Up

I recommend warming up at home because at the venue it can be too crowed and rushed. Allow enough time at home (after you have eaten) to warm up. Start off with some light cardio for 10 minutes. Build a light sweat so you know your body temperature has increased and your soft tissues like muscles and tendons will be more receptive to stretching and mobilisation. If you need to go downstairs onto the road to do this then go for it. A short jog around the block would be great! Once your cardio is over go back upstairs or find a comfortable place to start your stretching routine. Again nothing new, just the routine you have refined over the months of training and that opens up your body best and gets it going. This should be mostly dynamic is nature working through the full range of motion and less static holds and sustained over pressure. Don’t worry about cooling down after your stretching and prior to your race starting. The joints and muscles will be sufficiently mobilised for you to start your race feeling comfortable and able to get into your stride quickly and comfortably. The aim of your warm up is to get you into your stride as quickly as possible in the race so you don’t waste time running at a slower pace and gently working yourself up to your race pace as you warm up.

5. At the venue

Try to get there early to get a good spot. It’s not always possible to get to the front of the line but being as close to the front as possible does help you in that you will have less people to run around once you start.

If the race is a smaller one and the runners are fewer in number, you might want to consider letting everyone else go ahead and then starting last. Your race only officially starts when your timing chip crosses the mat so the gun at the start of the race is not that important. You have your own watch anyway so you can start it whenever you cross the line.

6. Racing Line

The fastest time between two points is often the shortest distance between them. For this reason don’t waste time by running further. When you are running plot a straight line from where you are to the apex of the bend in the road in front of you. Run straight to that point. This will save you bobbing and weaving down the road adding a few extra meters to your run here and there. I find I can add as much as 150m to a half marathon distance by not running a good racing line. That can be as much as 20 to 30 seconds extra time which can be the difference between my new personal best and not. The shortest distance is a straight line. Avoid extra meters by running in curves and bends.

Be careful at the start not to get boxed in behind slow runners. Pick your lines so you can settle into your race pace as quickly as possible and avoid losing time and energy. I find running along the side of the road is best in races with large numbers of runners. Getting boxed in at a slower pace is one of the most disastrous things when it comes to trying to run a fast time.

7. Race Pace

I believe a steady state running technique is the best. Use a smart phone running app or a Garmin GPS watch to run at the pace you know will get you the time you want. The majority of the training programs I give to runners are based on this principle. Too often inexperienced runners will blow their legs too early in a race by running faster than they have trained to do. This often happens because of excitement and poor understanding of how to pace yourself properly. Having an app or a watch that gives you real time data on your pace every kilometre is a huge help!

Another popular running technique is to run at 5 -10 seconds below your race pace for the first third of the run. This is increased to race pace in the middle third and accelerated to 5 – 10 seconds faster in the final third. This approach in okay but I feel that it may be used by runners who have not warmed up correctly and who need that first third of the race to do so. You really need to know your body very well with this technique so you know when to shift gears. It is very effective if done properly but I find it goes wrong more often than it works in my personal experience.

8. Fuelling Strategy

Don’t rely on the race organisers to decide your fuelling strategy by the placement of their water stations to tell you when to drink or eat. Know your fuelling strategy weeks in advance of your race. This needs to be established in your training runs. It may be influenced by the seasons as colder seasons may need less hydration for example but know your fuelling strategy well.

My strategy is the following:
o Pre-race meal about two hours before the race.
o Sip on energy drink slowly during the next two hours.
o GU Gel 20mins before start. This is to replace the energy spent running around before the race and burned through nervousness. By taking it 20 minutes before the race I aim for it to be in my system by the start of the race and therefore I don’t start in a negative energy balance.
o GU Gel just before start. This should be available for my muscles about 20 to 30 minutes later.
o GU at 7km and 14km using the same reasoning.
o Between these GU Gels I would have the occasional sip of water. Not more than one mouthful every 1km.

Please take note that if you wait until you feel thirsty or tired then you are already too late in fuelling. If you drink at that time it will take time for that energy to reach your muscles and you will have exhausted your glucose supply by then. Try to avoid this by having a fuelling strategy that tops you up before you reach the empty point but that does not over load you so that you are feeling full and get gastric irritation as a result.

9. Use your arms

Your arms can be a great help to you when you are tired. If you increase your arm speed forward and backward, it will automatically increase your leg cadence too. This is particularly helpful running up hills or when you need an extra burst of speed for the finish line.

10. Use the downhill

Increase your stride slightly when running downhill. This will help you run faster without using too much energy to do so. Let gravity pull you down the hill. Only 10cm extra stride length per stride can make a difference.

This strategy is good for short hills like we will face at SCMM but for longer hills of 1000m or more, you may want to use a more conventional approach of shortening your stride to decrease ground reaction forces going up your legs on contact.

11. Finish strong.

Never finish a race at anything less than full speed. Even if it’s just the last 100m make sure you do it flat out. I always aim to run the last 1km as fast as I possibly can. I aim to be exhausted when I cross the finish line. Remember pain is temporary the elation of achieving your goal is forever!

Body caveats in endurance running physiology first

BODY CAVEATS IN ENDURANCE RUNNING…physiology first
Dr Arvind Gupta .

Running is popular in it’s own right and a fitness activity across the globe, and it’s sad that +50% runners get injured every year.

Still articles keep pouring in about avoiding injuries only on belief, arguments and theories and possible links …..eg exhalation on same foot, exhale long, inhale long, sync strides to respiration as the impact load is 3 times body weight and so on.

STRIDE — BREATH LOCKING .

As marathon is all about running in aerobic zone

There’s a fancy emphasis on respiration…Why is it so?
Mammals have an in built mechanism to lock into stride – breath mechanism known as LOCOMOTOR RESPIRATION COUPLING (L-R-C)
Human evolution suggest that humans can also train to lock stride -breath mechanism hence sync them to avoid injuries.

BODY CAVEATS TO LOCOMOTION RESPIRATION COUPLING (stride-breath coupling)

Human diaphragm is vertical and mammals have a horizontal diaphragm so mammals always tend to sync strides with respiration celebrex cost.We manage a sync only in a slow jog or at high speed running.

Breathing is INVOLUNTARY and governed by respiratory centres in the brain stem and is BEYOND YOUR CONSCIOUS CONTROLas the respiratory centres work on feedback mechanisms from receptors present in intercostal muscles, lungs and diaphragm

Breathing is also fine tuned by chemoreceptors, near your heart and aorta which respond to changing blood gas levels, pH of blood. Also an efficient expiratory centre is present in the brain stem which activates during exercise only and increase your respiratory rate to changing pH level while running .

Any attempts to sync breathing with foot steps decrease venous return to the heart which in turn affects the cardiac output .

CO2 dissolve and dissociates faster in blood itself so forceful expiration removes CO2 faster to bring in more O2 is ill founded.

Expiration is pure passive recoil of lung ,diaphragm and chest muscles .You cannot add to passive recoil by any means .Any forced expiration hampers the next respiratory cycle .

Cerebral cortex has no role in respiration . Humans breathing on count of footsteps tries to bring volition into play …..a function of higher centres in the brain L C R of 2-2, 3-2, 2-3, 2-1 conscious control will always concentrate on FOOT STRIKE more than respiration.The brain is designed so . Its known as EMBODIED COGNITION which activates the neuronal circuitry of running mere by thinking about it . No such neuronal circuits exist with respiration as its involuntary
The only time when cerebral cortex coordinates with respiration is COUGHING SWALLOWING & SPEAKING.

A word about difference in MALE -FEMALE breathing ,males are Abdomino-thoracic(use more abdominal muscles) and females are thoraco-abdominal breathers (use more chest muscles than belly). 
Trying to sync strides with respiration in females is less efficient than males as females use accessory muscles of neck in breathing which affects the diaphragm movements .

LEARNING to sync breathing and strides …….first breathing by lying down ……then on slow jog ……..and then onto the run is ill founded (2-2, 2-3, 3-2, etc). The sync will happen only when BODY ADAPTS TO A PHASE OF MINIMAL OXYGEN-CONSUMPTION (RUNNING ECONOMY ): (METABOLIC FITNESS )

The body will adapt eventually with time and max. training into aerobic zone.(lydiard way of running )
INSPIRING (3-2) more or EXPIRING (2-3) hampers with this body adaptation of lowest O2 consumption ,venous return ,metabolic changes while running hard . Let the body do it’s best .

IMPACT IMPACT LOAD WHILE RUNNING

Sync the respiration with strikes otherwise the 2-3 times body weight impact load will bring injuries ….read in many articles .IMPACT LOAD DEPENDS ON THE GLUTES STRENGTH (Which have weakened over years of sitting ….sitting long hours .)it has affected THIGH EXTENSION , ABDUCTION AND THIGH ROTATIONS AND FORWARD TILT OF PELVIS eventually affecting HIPS movements…….you run through hips always…….RIGHT.

BODY CAVEATS

The foot contact time is very short 0.22-0.3 secs
Neutral and fore foot strikers impact is very less. Heel strikers always take care .
Human pelvis is narrow restricting the load moving down the contact plane .
The movement of 9kg internal organs is 2-4cm only ….over a bag of air- fluid(5-6 litres ) filled intestines which buffers the load.
Core muscles have a respiratory and stabilizing role .It goes more towards respiratory role while running so as to adapt to minimize oxygen needs ……any attempts here to sync will destabilize the LUMBAR SPINE ……inviting injuries.
Core muscles forms a stable ball while running and distribute the impact load to all sides. CORE MUSCLES ALWAYS CONTRACT BEFORE THE FOOT STRIKE .
While running the centre of gravity may remain high at foot strike .
Gluteus medius and minimus muscles are leg stabilizers. STRENGTHEN BOTH GLUTES .
Check your upper and lower part of kinetic chain (hips and foot)if you are injury prone .

CHECK HAEMOGLOBIN ALWAYS ……just an add on

A word about the Hb levels…A Hb molecule carries 4 molecules of oxygen
A 15 mg Hb level has a O2 carrying capacity of –20.8ml/dl
10 mg Hb level has a O2 carrying capacity of–13.9mg/dl
Marathon is all about aerobic run. Check this premise well….
Take iron supplements .Your doctor runner friend advised you long back .

CHALLENGE YOUR EFFORT ..NEVER CHALLENGE THE FEEL….
ENJOY RUNNING .
