- “Repeated load” moving forward while supporting weight
In running,
Each time you land, you get two to three times as much impact as your weight
use the reaction to kick the ground
Repeat the action thousands of times.
Muscles used primarily at this time:
quadriceps femoral muscle (front of thigh)
Hamstrings (back of thighs)
the gluteus maximus (bump)
the triceps of the lower thigh (calf)
👉 Improve muscle strength and muscle endurance by repeating self-weight training hundreds to thousands of times. - extensible contraction (excentric contraction)
When you land, your muscles
work hard while being stretched out It has a special function.
by this
Fine damage to muscle fibers
be more strongly reconstructed on recovery
👉 This is the reason why my legs get stronger especially when I go downhill or when I speed up. - adaptation of the nervous system
by repetition
increase muscle mobilization efficiency
reduce unnecessary power
👉 “Even with the same legs, you won’t get tired and can use them strongly.”
② theory in which the cardiovascular system is trained - surge in oxygen demand
When you run, your leg muscles require a lot of oxygen.
To respond:
Heart rate ↑
Single stroke volume ↑ (heart becomes stronger)
effective use of respiratory rate and lung capacity ↑
👉 Continuous load is applied to the heart and lungs. - Improved cardiac pumping
On a continuous run:
development of the heart muscles (especially the left ventricle)
Increased blood volume per beat
Result:
experience a decrease in resting heart rate
make breathing difficult even with the same exercise
👉 This is the condition where cardiopulmonary functions have improved. - increased capillaries and mitochondria
Within the muscle:
increase capillaries → oxygen supply up
increase mitochondria → increased energy production efficiency
👉 “A body that can run for a long time and comfortably.”
③ Why does running work for both
The point is the simultaneous load.

👉 If your legs don’t move, you can’t train your heart and lungs, and if your heart and lungs are weak, you can’t use your legs
This interdependence is the strength of running.
④ Supplement: Differences from muscle training
running
→ muscular endurance, neural efficiency, cardiopulmonary strength
Muscle training (squat, etc.)
→ maximum muscle strength and muscle hypertrophy
👉 Combining both is the most efficient.
if necessary
“The difference between jogging and dash.”
“Why does running slowly and for a long time make your heart and lungs stronger?”
