However in recent times, sports science experts have additionally been wanting into a unique technique which may distinctly profit Miami’s staff (and is one thing many extra of us have entry to, whether or not we would like it or not): warmth coaching.
Exercising within the warmth provides an additional dimension of bodily and psychological problem to a exercise, for the reason that thermal stress of the heat and humidity makes it harder in your physique to remain cool sufficient. Because of this some athletes intentionally topic themselves to scorching environments to assist their our bodies adapt by rising blood plasma quantity.
However, is warmth coaching protected? And is it as efficient as altitude coaching?
The advantages of warmth coaching vs altitude coaching
Warmth coaching entails exercising in excessive temperatures (85 to 100 levels F) to extend the physique’s skill to dissipate warmth and keep core temperature.

“It may well enhance endurance, cut back fatigue, and improve cardiac operate and thermoregulatory responses,” explains train physiologist Karissa Bollinger, an ultramarathon runner, and the proprietor of Golden Teacher Wellness LLC. “Moreover, it could enhance muscle glycogen storage and enhance cardio and anaerobic efficiency.”
Whereas there are some overlapping advantages between warmth coaching and altitude coaching, the rules are fairly totally different.
Altitude coaching entails often exercising at excessive altitudes (often over 1,500 meters above sea degree) to enhance athletic efficiency.
“It stimulates the physique’s manufacturing of purple blood cells and helps enhance the quantity of oxygen carried within the blood, which can assist enhance endurance efficiency,” she notes. “Moreover, altitude coaching can also enhance running economy and enhance the anaerobic threshold.”
She explains that whereas sure athletes might profit from doing both warmth coaching or altitude coaching (or each), whether or not it’s higher to do warmth coaching or altitude coaching primarily is dependent upon that athlete’s particular sport, occasion, and particular person wants.
“Typically, warmth coaching might profit sports activities equivalent to long-distance working or biking in scorching, humid situations,” suggests Bollinger. “Then again, altitude coaching could also be extra helpful for endurance and high-intensity sports activities equivalent to distance working, biking, rowing, and cross-country snowboarding.”
What are the physiological variations that happen when coaching in warmth vs altitude?
Within the warmth, the physique experiences a spread of diversifications to deal with the elevated thermal stress. “These embody a rise in blood circulation to the pores and skin, which helps dissipate warmth by sweating and vasodilation of the blood vessels. In consequence, plasma quantity and coronary heart price might enhance to assist keep blood stress throughout train,” explains Bollinger. “Moreover, the physique will increase its manufacturing of warmth shock proteins and prompts the renin-angiotensin-aldosterone system, which helps regulate fluid steadiness and electrolyte ranges in response to dehydration.”
Bollinger contrasts this towards the physiological diversifications that outcome from coaching at altitude, that are caused because of the decreased availability of oxygen within the air at greater elevations.
“These [changes] embody a rise in air flow, a rise in purple blood cell manufacturing, and a rise in capillary density. These diversifications assist the physique transport oxygen extra effectively to the working muscle tissue and keep cardio efficiency at greater altitudes,” explains Bollinger. “Moreover, coaching at altitude can also enhance muscle buffering capability, which helps delay the onset of fatigue throughout high-intensity train.”
Basically, there are shared advantages, however every environmental stressor results in totally different physiological diversifications. Warmth coaching primarily helps to reinforce thermoregulatory operate (your physique’s cooling mechanisms) and enhance warmth tolerance, whereas altitude coaching helps to enhance oxygen transport, cardio capability, and oxygen utilization at excessive altitudes.
Additionally, athletes usually have to spend a number of weeks to months at excessive altitude to see optimistic diversifications. But analysis suggests you may see the consequences of warmth coaching after only one to 2 weeks of figuring out in excessive temps for an hour a day, says Bollinger.
What are the downsides of warmth and altitude coaching?
There are limits to how a lot you may safely prepare within the warmth—extended publicity can enhance your threat of warmth exhaustion, dehydration, and different heat-related illness, warns Bollinger. Look out for unusually heavy sweating, weak spot, fatigue, dizziness, headache, muscle cramps, or nausea. “In extreme circumstances, warmth stroke might happen, which is a doubtlessly life-threatening situation that requires fast medical consideration.”
Bollinger additionally factors out that warmth coaching will not be as efficient for bettering cardio capability and train economic system as altitude coaching. And it merely feels tougher, which may result in much less intense exercises (or skipping exercises altogether).
In the meantime, she says that coaching at excessive altitudes can put you at risk for altitude sickness, which may trigger signs like complications, dizziness, and nausea. Bollinger explains that whereas altitude coaching is meant to enhance cardio operate, if it’s important to cut back the depth and length of your coaching because of the issue figuring out in air with much less oxygen, altitude coaching can backfire. Additionally, know this: “The diversifications induced by altitude coaching could also be short-lived and should not switch on to sea-level situations,” she provides.
How on a regular basis athletes can take benefit
Altitude coaching is usually a luxurious solely possible for elite athletes, however Bollinger says that leisure athletes can incorporate warmth coaching or altitude coaching into their routine if they’ve the means and medical clearance to take action (and ideally a coach who might help them do it safely).
Even for those who dwell at decrease altitudes, you may strive sporting an altitude coaching masks or take an altitude coaching class.
Warmth coaching is extra probably going to be essentially the most possible possibility for the common particular person, although. “On a regular basis athletes can attempt to incorporate warmth publicity into their coaching routine by sporting further layers of clothes, figuring out in a heated room or sauna, or in the course of the hottest components of the day,” Bollinger suggests.
To assist maximize the protection and effectiveness of warmth coaching, Bollinger shares some ideas:
1. Acclimatize progressively:
Begin with shorter warmth publicity exercises. “It’s best to progressively enhance the length and depth of warmth publicity over time to keep away from heat-related diseases,” advises Bollinger. It will assist give your physique time to regulate to the warmth.
2. Keep hydrated:
Drink loads of water earlier than, throughout, and after your exercise to take care of correct hydration.
3. Gown appropriately:
Put on light-colored, loose-fitting garments that permit sweat to evaporate. Keep away from darkish colours or tightly fitted clothes, since it could entice warmth.
4. Time your exercises:
When it’s a real scorcher on the market, keep away from exercising in the course of the hottest a part of the day. As an alternative, intention for early morning or late night exercises when the temperature is cooler.
5. Take breaks:
It’s important to take frequent breaks to chill down for those who really feel such as you’re overheating.
6. Use sunscreen:
Apply sunscreen earlier than heading outdoors to guard your self from dangerous UV rays.
7. Take heed to your physique:
When you really feel dizzy, lightheaded, or expertise some other uncommon signs, cease your exercise instantly and relaxation within the shade or a cool space.
8. Do not skip the calm down
Assist deliver your physique again to resting progressively by a stable cooldown, like a 10-minute stroll on the finish of your run.
9. Seek the advice of your physician:
When you have an underlying medical situation or are taking any medicine, seek the advice of your physician earlier than beginning a warmth coaching program.
