El ejercicio que más ALARGA la vida NO es caminar: son 3 PISOS al día (bajarlos es MEJOR)

Summary

Dr. Borja Bandera argues that stair climbing can complement walking by adding a brief, more demanding mix of cardiovascular work, leg strength, balance, and coordination. The central message is to start gradually, build the habit, and use the handrail or modify the activity when needed—not to push through sharp pain or unsafe breathlessness.

Why stairs may help

• More effort than ordinary walking: Each step lifts your body against gravity, so climbing can raise your heart rate and energy use more quickly than a level walk.
• Strength and power: Climbing works the legs in a repeated single-leg movement and recruits fast-twitch muscle fibers, which tend to decline with age.
• Balance and coordination: Each step challenges balance and body awareness, potentially helping train skills relevant to fall prevention.
• Metabolic and cardiovascular fitness: The video describes stair climbing as a short, vigorous activity that can fit into daily routines.

Evidence discussed

• An analysis of nearly 460,000 UK Biobank participants found that climbing about 50 steps a day was associated with roughly 20% lower risk of heart attack and stroke.
• A meta-analysis presented by the European Society of Cardiology found regular stair climbing was associated with 24% lower overall mortality and 39% lower cardiovascular mortality.
• These are observational associations, not proof that stair climbing alone caused the differences; people able to climb stairs may already be healthier.
• The speaker also discusses “VILPA”—short bursts of vigorous activity woven into daily life, such as rushing up stairs. In one study of sedentary people, three or four bursts lasting one to two minutes each were associated with lower mortality.
• A four-flight stair test is presented as a rough fitness check, not a diagnosis. In the cited study, completing four flights briskly in under a minute was associated with good fitness; taking over 90 seconds suggested lower fitness.

Practical ways to start and progress

• Begin with a manageable amount: The video suggests around 50–100 steps a day—roughly three to six floors—as a possible target for many older adults, while emphasizing that ability and circumstances vary.
• Progress gradually: Start with only part of a flight if needed, then add floors over time. The story of Antonio illustrates building up gradually rather than forcing the full climb on day one.
• Make it a routine: Choose a staircase at home, work, or a transit stop and replace one elevator or escalator trip with stairs.
• Try a four-flight check only if appropriate: The speaker says to attempt it only if you have no symptoms, known heart condition, or other limitation, and to record your time to compare later.
• Use a handrail when starting, recovering from injury, or needing extra security. The speaker stresses that holding the rail is not “cheating.”
• Carry groceries only if you are ready: Distribute the load evenly, start with a manageable weight, and take rests between floors if needed.

Going up versus going down

• The video distinguishes concentric work when climbing from eccentric work when descending.
• Going up emphasizes cardiovascular effort and leg strength. Going down puts the leg muscles under tension while they control each step, and may offer a training stimulus with a lower heart-rate demand.
• A study of women over 60 cited in the video found improvements in several health measures among participants who descended stairs. The speaker presents ascent and descent as different, complementary stimuli, not as a reason that descending is always better.
• Descending may cause more muscle soreness. Go slowly and use the rail if needed.

Knee and back considerations

The speaker says stair use is not automatically harmful to knee cartilage, but the knee bears more load on stairs than during level walking.

The video notes an association between climbing more than 150 steps a day and higher knee osteoarthritis risk in one analysis, especially among people with genetic predisposition. It recommends moderating activity and adapting the amount to your strength and condition.

For knee osteoarthritis, the suggested modifications are:

• Try climbing first, since the speaker says it may be more comfortable than descending.
• Descend slowly while holding the rail, or take the elevator down and walk back up.
• If a full flight is too much, practice a single step repeatedly with support.
• Mild discomfort that settles may be acceptable; sharp pain, swelling, or a locked knee is not.

The video describes stair climbing as generally gentle on the lower back for many people, but notes that serious cases may differ. A diagnosed back condition or significant symptoms call for individualized medical advice.

Technique and safety tips

• Do not use your phone while descending. Keep your attention and eyes on the next step.
• Use the handrail if it helps you feel secure or reduces strain.
• Place most of your foot on the step rather than climbing on your toes; push through the foot, including the heel.
• Avoid rushing or increasing the number of stairs faster than your strength and balance allow.

Options for people already in good shape

The speaker offers three higher-intensity progressions:

• “Glycolytic snack”: Three 20-second hard climbs, with two minutes of rest between them, three days a week. Do not sprint if it makes you unstable.
• Vertical rucking: Climb with a backpack, starting around 5 kg and increasing gradually. The speaker advises against carrying added weight down, particularly with knee wear or osteoarthritis.
• Two steps at a time: This increases the range of motion and shifts more work toward the glutes and hamstrings. It requires sufficient strength and control.
