Document Content and Description Below

4 broad reasons for why we study PA Correct Answer: 1) Our Design 2) Environmental Mismatch 3) PA is important for physical health 4) PA goes beyond physical health Our Design Correct Answer: ... - Humans have evolved to be physically active, we are designed to move around. - ex. Plants are not made to move around - ex. Kangaroo is designed to move around at high speeds - Humans have muscles, long arms and legs (no roots) so moving around is important. - The human body responds well to the physical demands of PA, we can adapt well. - Human body does not respond well to being sedentary. - Survival depends on PA -Selctive Pressures Selective Pressure Correct Answer: - Environmental factors that affect the reproduction capabilities of a species. - ex. Giraffes have long neck, but there could have been a selective pressure for giraffes to need to be able to reach high for food (fires), those genes may have been transferred through generations. - example of selective pressures for giraffes: > elevated food sources > longer necked giraffes more likely to survive > genes passed down - Selective pressures for humans: > Finding water/ building shelter > Escaping predation > Transportation Environmental Mismatch Correct Answer: - The selective pressures that favoured a capacity for physical activity are no longer present. - We have designed our environment to minimize physical activity (ex. cars, buses, Segway's, subways, ordering things online...) PA is important for Physical Health Correct Answer: What this class is all about: - Cardiovascular disease - Obesity [Show More]
