Why did astronauts back in 1960s return to earth with muscles so weak that they had difficulty walking when they returned to the earth?
After any period in a place where the force of gravity is less than on the surface of the earth (or nearly weightless in orbit), muscles will begin to atrophy. The longer in space the weaker you get becuase the muscles do not have to counter the force of gravity. This also includes the heart muscle so the astronauts must be monitored while in space and for a while after their return to earth.

How far did the astronauts travel on the moon?
The actual time spent outside walking on the moon was 2 hours 13 minutes from the time Armstrong set foot on the surface until they both returned to 'Eagle' and closed the hatch.
What effect does microgravity have on muscles?
In the near-zero gravity of Earth orbit, muscles that are ordinarily used for standing, walking, or balancing are not needed. During prolonged periods in space, astronauts have to work these muscles to keep them from atrophying (reducing in size and strength).
How long Apollo 11 astronauts spend walking on the moon?
In the Apollo 11 mission the astronauts had a moonwalk lasting 2 hours and 31 minutes.
Do astronauts need to walk on the moon?
Astronauts do not need to walk on the moon to conduct experiments or gather samples. They can use rovers and specialized equipment to explore the surface without walking. Walking on the moon would be difficult due to the moon's low gravity and lack of atmosphere.
How many astronauts wolked on the Apollo moon landing?
A total of 12 astronauts walked on the moon during the Apollo missions, from 1969 to 1972. Each Apollo mission had a team of astronauts, with two astronauts landing and walking on the moon's surface during each mission.
What are the main symptoms of Wernicke's syndrome?
include ataxia (difficulty in walking and maintaining balance), paralysis of some of the muscles responsible for movement of the eyes, and confusion
What are some parkinson diease syptoms?
Some of the symptoms of Parkinson's disease are Tremor or shaking, stiff and aching muscles, weakness of face and throat muscles, slow and limited movement and difficulty with walking and balancing.
What symptoms would a person have if their cerebellum has been injured?
The cerebellum is involved in muscle control, especially for movement and balance and muscle tone. Some symptoms would include difficulty balancing, difficulty telling when to stop walking forward, tremors, staggering when walking, weak muscles, slurred speech and abnormal eye movements.
What muscles are targeted when walking?
When walking, the major muscles targeted are the quadriceps, hamstrings, glutes, calves, and hip flexors. These muscles work together to move and stabilize the body during the walking motion.
Does running and walking use the same muscles?
Running and walking does use the same muscles in the body. Three of the main muscles used in the legs are hamstrings, quadriceps and gluteal muscles.
What do astronauts need when walking in space?
I am not sure, ask NASA
Are buttock muscles used when walking?
The gluteus muscles are used when walking. They support the upper body in an upright posture.
How far did the astronauts travel on the moon?
The actual time spent outside walking on the moon was 2 hours 13 minutes from the time Armstrong set foot on the surface until they both returned to 'Eagle' and closed the hatch.

What exercise helps our muscles?
walking
Which muscles are utilized when walking?
The muscles utilized when walking include the quadriceps, hamstrings, glutes, calves, and core muscles. These muscles work together to move the legs and stabilize the body during each step.
How long Apollo 11 astronauts spend walking on the moon?
In the Apollo 11 mission the astronauts had a moonwalk lasting 2 hours and 31 minutes.
