However in recent times, sports activities science specialists have additionally been wanting into a special technique that 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 warmth and humidity makes it tougher on 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 secure? And is it as efficient as altitude coaching?
The advantages of warmth coaching vs altitude coaching
Warmth coaching includes exercising in excessive temperatures (85 to 100 levels F) to extend the physique’s means to dissipate warmth and preserve core temperature.

“It may well enhance endurance, scale back fatigue, and improve cardiac perform and thermoregulatory responses,” explains train physiologist Karissa Bollinger, an ultramarathon runner, and the proprietor of Golden Trainer Wellness LLC. “Moreover, it might improve 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 includes repeatedly exercising at excessive altitudes (normally over 1,500 meters above sea degree) to enhance athletic efficiency.
“It stimulates the physique’s manufacturing of crimson blood cells and helps improve the quantity of oxygen carried within the blood, which can assist enhance endurance efficiency,” she notes. “Moreover, altitude coaching may enhance operating economic system and improve the anaerobic threshold.”
She explains that whereas sure athletes could 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 determined by that athlete’s particular sport, occasion, and particular person wants.
“Basically, warmth coaching could profit sports activities akin to long-distance operating or biking in scorching, humid circumstances,” suggests Bollinger. “However, altitude coaching could also be extra helpful for endurance and high-intensity sports activities akin to distance operating, 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 variety of diversifications to deal with the elevated thermal stress. “These embrace a rise in blood stream to the pores and skin, which helps dissipate warmth by sweating and vasodilation of the blood vessels. In consequence, plasma quantity and coronary heart fee could improve to assist preserve 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 stability and electrolyte ranges in response to dehydration.”
Bollinger contrasts this in opposition to the physiological diversifications that end result from coaching at altitude, that are caused because of the diminished availability of oxygen within the air at greater elevations.
“These [changes] embrace a rise in air flow, a rise in crimson blood cell manufacturing, and a rise in capillary density. These diversifications assist the physique transport oxygen extra effectively to the working muscle groups and preserve cardio efficiency at greater altitudes,” explains Bollinger. “Moreover, coaching at altitude may improve 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 perform (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 sometimes must spend a number of weeks to months at excessive altitude to see optimistic diversifications. But analysis suggests you’ll be able to see the results of warmth coaching after only one to 2 weeks of understanding 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’ll be able to safely practice within the warmth—extended publicity can improve your danger of warmth exhaustion, dehydration, and different heat-related sickness, warns Bollinger. Look out for unusually heavy sweating, weak point, fatigue, dizziness, headache, muscle cramps, or nausea. “In extreme circumstances, warmth stroke could happen, which is a doubtlessly life-threatening situation that requires fast medical consideration.”
Bollinger additionally factors out that warmth coaching might not be as efficient for enhancing cardio capability and train economic system as altitude coaching. And it merely feels more durable, which might result in much less intense exercises (or skipping exercises altogether).
In the meantime, she says that coaching at excessive altitudes can put you at danger for altitude illness, which might trigger signs like complications, dizziness, and nausea. Bollinger explains that whereas altitude coaching is meant to enhance cardio perform, if you need to reduce the depth and period of your coaching because of the issue understanding 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 circumstances,” 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 may help them do it safely).
Even should you reside at decrease altitudes, you’ll be able to strive carrying an altitude coaching masks or take an altitude coaching class.
Warmth coaching is extra seemingly going to be probably the most possible choice for the typical individual, although. “On a regular basis athletes can attempt to incorporate warmth publicity into their coaching routine by carrying further layers of clothes, understanding in a heated room or sauna, or throughout the hottest elements of the day,” Bollinger suggests.
To assist maximize the security and effectiveness of warmth coaching, Bollinger shares some ideas:
1. Acclimatize step by step:
Begin with shorter warmth publicity exercises. “It’s best to step by step improve the period and depth of warmth publicity over time to keep away from heat-related diseases,” advises Bollinger. This can 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. Costume appropriately:
Put on light-colored, loose-fitting garments that enable sweat to evaporate. Keep away from darkish colours or tightly fitted clothes, since it might lure warmth.
4. Time your exercises:
When it’s a real scorcher on the market, keep away from exercising throughout the hottest a part of the day. As a substitute, goal 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 should you really feel such as you’re overheating.
6. Use sunscreen:
Apply sunscreen earlier than heading exterior to guard your self from dangerous UV rays.
7. Hearken to your physique:
If you happen to really feel dizzy, lightheaded, or expertise another uncommon signs, cease your exercise instantly and relaxation within the shade or a cool space.
8. Do not skip the quiet down
Assist convey your physique again to resting step by step by a strong cooldown, like a 10-minute stroll on the finish of your run.
9. Seek the advice of your physician:
