Benefits of Heat Training

Human’s ability to sweat allows us to cool our bodies even when running in extremely hot environments. However, the need to circulate blood out to the skin periphery for this cooling draws this much needed blood away from working skeletal muscles and causes a lower cardiac filling and stroke volume leading to higher heart rates at any given work load. The loss of electrolytes and fluid via the sweating (without adequate replacement) will lead to a decreased blood volume and add additional demand on an already taxed heart.

Heat acclimatization is one way to improve ones ability to run well in a hot environment and in extreme cases is necessary for survival. Heat acclimation is merely when an individual has been conditioned to maintain a higher blood plasma and volume level, increased sweat rate, a decreased salt amount in the sweat produced, decreased fatigue rate of sweat glands, and quicker onset of sweating when placed in the heat. These changes are all needed to meet the demands on the body mentioned above. Heat acclimation is produced via repeated exposure to heat sufficient to raise body core temperature. This is most effectively done by exercise (skeletal muscle contractions) vs. sitting in a hot room. Only a few sessions of one hour of moderate exercise in the heat will produce an effect in un-acclimated individuals with changes being seen in a few days.

Some interesting highlights to acclimatization:

  • One can become acclimatized to heat and cold at the same time. Even with training bouts being on the same day in the different environments.
  • Most of the improvements in heart rate, core and skin temp, and sweat rate are acquired in just ONE week of heat exposure. Heart rate adaptations are seen in just 4-5 days! However increases in sweating and a feeling of “ease of walking” in a hot environment can take up to one month to occur.
  • More is gained from a 100 minute bout of heat exposure exercise than one 50 minute bout, but adding bouts beyond 100 minutes of exposure did not quicken adaptation.
  • Heat exposure adaptations have been studied to disappear as quickly as one week if the subject is not re-placed in the heat, but may last as long as 3 weeks in some individuals.

Know what you’re up against

Of all the adversities that runners and marathoners face, heat is the number one offender. This is because it can bring on two conditions that can negatively affect your performance… Overheating and Dehydration.

Overheating is the result of inadequate cooling; when the body cannot keep up with the demands of evaporation of water from your skin. When the body heats up internally, it starts to sweat and sends more blood to the skin where it is cooled by coming into contact with the relatively cooler skin. However, while running, your body’s demand for oxygen to the muscles means less blood will flow to the skin and this is when overheating occurs. And thus begins the tug-of-war within your body, especially if you want to keep up a certain pace. Either the blood (and oxygen) goes to your muscles to keep up with the pace demands and you start to overheat because less blood is going to the skin for cooling – OR – the blood goes to the skin for cooling, but less blood goes to your working muscles meaning you’ll be forced slow down.

Dehydration is the process of losing fluid from the body, in this case through sweat. As you sweat you lose water and electrolytes. That’s why drinking a sports drink containing electrolytes, as well as water, is so important. Because running in the heat exacerbates both overheating and dehydration, it is important to take precautions when running in the heat.

PRECAUTIONS FOR RUNNING IN THE HEAT
1) It takes approximately two weeks of consistent running in the heat and humidity to acclimate to warmer conditions.

2) Remember that thirst is not an indicator of dehydration. Once you are thirsty, you are already low on fluids. Indications of dehydration are an elevated heart rate during and after your run and dark, golden-colored urine. After your run, keep drinking fluids until your urine is clear.

3) During your run, drink about 4 to 8 ounces of water and/or sports drink every 15 to 20 minutes.

4) Weigh yourself before and after your run. Drink 16 ounces of fluid for every pound of weight lost. *Important note here… do not use this as a method of weight loss!

5) Apply a sunscreen of at least SPF #15. Make sure that it is a non-drip formula that won’t drip into your eyes.

6) Wear sunglasses that filter UVA and UVB rays and/or wear a cap with a visor.

7) Wear light-colored micro-fiber clothing.

8) Run when your shadow is taller than you are, and when the sun is not high in the sky. If you run in the morning, you’ll avoid the heat, but may encounter a higher humidity. The air quality is also better in the morning, since ozone levels increase soon after dawn, peak at midday, and then again in the early evening. Times to avoid running are noon till 3pm.

9) Eat salty foods and drinks such as pretzels and tomato juice.

10) Check the Heat Index Chart for apparent temperature. This is the number that calculates the air temperature with the relative humidity to determine what the temperature feels like and if there is a risk of a heat-related illness.

HEAT INDEX CHART

Apparent
Temperature
Heat Stress Risk with Physical Activity
and/or Prolonged Exposure
90° – 105° Heat cramps or heat exhaustion possible
105° – 130° Heat cramps or heat exhaustion likely Heatstroke possible
130°+ Heatstroke highly likely

SIGNS OF HEAT-RELATED ILLNESS
1) HEAT CRAMPS
Causes: Loss of electrolytes and accumulation of lactic acid in the muscles.
Conditions: Muscle cramps and/or spasms, heavy sweating, normal body temperature.
Treatment: Drink water and sports drink, slow down, massage affected area.

2) HEAT EXHAUSTION
Causes: Intense exercise in a hot, humid condition and loss of electrolytes.
Conditions: Profuse sweating, possible drop in blood pressure (less than 90 systolic, the top number), normal or slightly elevated body temperature, lightheadedness, nausea, vomiting, decreased coordination, possible fainting.
Treatment: Rest in a cool place, drink water and sports drink, if BP drops below 90 systolic, call EMS, avoid activity for at least 24 hours, refrain from running or exercising in the heat for at least one week.

3) HEAT STROKE
This is a medical emergency!
Causes: Intense exercise in a hot, humid condition, older age, dehydration, obesity, wearing heavy clothing, running in the heat when you have an infection or fever, certain drugs such as amphetamines, diuretics, beta blockers, cardiovascular disease, poor acclimatization, high blood pressure.
Conditions: High body temperature (106 or higher), lack of sweating characterized by dry, red skin, altered consciousness.
Treatment: Call EMS! Rest in a cool place, remove clothing to expose skin to air, apply ice packs or cool water to groin, underarms, neck (stop if shivering).

Final verdict

Be sure to undertake the desired heat adaptations gradually, through easy sessions. Don’t rush or overdo the acclimation process. Heat injuries can have severe consequences. Never attempt to “tough it out”.

Overheating can be dangerous (which is why heat acclimation exists, of course). If you begin to feel ill during any of the acclimation sessions, slow down or stop. It can also help to have water/sports drink with you during your run.

The moral of the story is don’t shun running in the heat, you are actually benefiting from it. Embrace it, enjoy it, and don’t be stupid.

New Route, New Routine and Rainy Sunday

Last Sunday I wrote about my trail and LSD training with Sir Enrique (check it here) and it turns out a great training for the both of us and decided to have another one last Sunday. If last week we focus on endurance and stability. This week we turn our attention in speed, addition of mileage and balance for trail.Earlier this afternoon it’s difficult to tell if you still want to continue the training or not due to bad weather. But with perseverance and willingness to push our body to the limit, we still carry on.

We made a new route and new routine yesterday (click here). First, run uphill and downhill (IRTM Alabang to Petron, Daang Hari). Second, LSD from Petron to Daang Reyna, rotonda. This stretch is 95% cement and 5% trail in the end of the road. I love this stretch because it’s not that polluted compare to Molino to Alabang Road and fewer cars are passing here. By the way that road lead you to Muntinlupa/San Pedro/SLEX. Back to our routine. So after the LSD, next is Sprinting in Evia football field (here) and finally LSD on our way back to Molino.

It was a tiring day and despite the bad weather we still manage to survive another Sunday training. I heard Sir Enrique lost 10lbs. and happy for the result. Mine, I lost track but definitely burn lots of calories. I guess this will be the last training for this month and resume the training again after the holy week. This time we’re planning to do this earlier because the next route will be Molino to San Pedro (WHAAATT!). I don’t know if Bullverine is serious or not but when I look at him “I see a man with a mission”.

Well, another day is over and my big day is 5 days away. I hope everything run smoothly and according to plan on that day. Stay tuned for my next review… See yah!

Running with Krupicka?

Last Sunday me and my running buddy decided to have a trail run in Petron, Daang Hari, Alabang. This is our first time to run here and finally we found trail routes near our place. Starting at Phoenix gas station in Bacoor to the meeting place took me approx. 30 minutes. On your way to Petron you can also encounter lots of uphill and downhill so I just take it lightly so that I can still keep up with Enrique later that afternoon.

Enrique a.k.a. “Bullverine” Sundiang was already there waiting for me, already warmed up. And so we quickly jump in to the trail as soon as I arrived at the place. Since Bullverine is running barefoot we decided to check the surface first in a slow pace and check if it is Ok. We look for broken glasses, sharp object and stone that might cause injury along the path. Of course we need an injury free training, right?

As soon as the surface is clean and good to go, we run in our normal pace. Bullverine serves as my pacer and train me for endurance, stability and balance. And also this serves as my preparation for the upcoming Salomon X Trail Run on the 31st of March. After our training we took some pictures for souvenir purposes. Our training went well, injury-free and we both happy with the result. I’m looking forward for our next trail training this coming Sunday (3-24-2012). For those interested runners who wants to join us just PM me or Enrique  in our Facebook account. See you on Sunday!
