A series of questions and answers related to maintaining peak performance in spaceflight, focusing on the challenges of muscle loss in microgravity. It explores the physiological effects of spaceflight on the human body, particularly muscle atrophy, and examines strategies for preventing and mitigating these effects. Interactive elements like matching exercises and diagrams, making it suitable for engaging students in learning about the physiological adaptations required for space travel.

Take a moment to imagine that you just landed on the surface of Mars. You exit your spacecraft and step onto Martian soil--the first human in history to ever do so. You look around you. What would you see? How do you feel? Most importantly, what would you do first? - Correct Answer-Check equipment/ devices for any damages Using the evidence in this report, what do you observe happening to astronauts during spaceflight? - Correct Answer-An increase in muscle loss A decrease in muscle size A decrease in muscle strength Why might muscle loss be a problem for the success of your mission? Such actions could lead to....(select all that apply) - Correct Answer-all answers So what are you doing about it? - Correct Answer-Find out why this issue is occurring in the first place Which of the following are you most likely to be doing once you get home? - Correct Answer-phone Do you think relaxing in this way will require the use of your muscles? - Correct Answer- No Take a look and match each video to the type of muscle shown. - Correct Answer- 1 - cardiac muscles... 2 - Smooth muscles... 3 - skeletal muscle... Heat production - Correct Answer-You are outside on a cold day and shiver Movement - Correct Answer-You spike a volleyball You pick up a glass...
Posture - Correct Answer-You stand in line... You get into the... Label the diagram appropriately - Correct Answer-Bicep-Contracting muscle Tricep- relaxing muscle Take a look at the soccer player as he kicks the ball across the field. Then, label the diagram to explain how this happens. - Correct Answer- 1 - Contracting 2 - origin 3 - relaxing 4 - insertion True - Correct Answer-Actin and myosin are... Contraction moves the... False - Correct Answer-Myosin is the... Contraction elongates... What differences do you notice after 17 days in space? (Select all that apply) - Correct Answer-There are fewer actin filaments What do you predict might occur as a result of fewer protein fibers? (Select all that apply) - Correct Answer-Decreased muscle size Decreased strength of muscle tissue Earth - Correct Answer-Uses lower body... weighed down Space - Correct Answer-weightless floats in microgravity Doesn't use as... Using only the evidence gathered from the activity above, predict what you think may be causing muscle loss in astronauts? - Correct Answer-Lack of loading on the body After a couple of weeks, which of the following best describes how your body changes?
Take a look at the astronaut exercise plan below. What changes would you recommend based on what you now know about resistive exercise? - Correct Answer-Keep resistive exercise as is What would you do to prevent muscle loss? - Correct Answer-make sure they are doing enough weightlifting so their lower body-specifically their legs-are working hard. They need to do resistive exercise. To maintain the muscle size and volume astronauts need to work out and do resistive exercises daily. They also need an adequate supply of macronutrients such as protein to support muscle development.
