Final answer:
In the study, the subjects in the gentle stretching group experienced improvement in muscular endurance, while the subjects in the aerobic exercise condition experienced improvement in cardiovascular health.
Step-by-step explanation:
In the study conducted by Erickson and colleagues (2011), older adults were randomly assigned to either a gentle stretching condition or a more intense aerobic exercise condition. The subjects in the gentle stretching group experienced ______ compared with subjects in the aerobic exercise condition.
Aerobic exercise, such as cycling, walking, and running, helps improve cardiovascular health and increases muscular endurance. On the other hand, anaerobic exercise, such as weight training or sprinting, increases muscle strength. Therefore, it can be inferred that the subjects in the gentle stretching group experienced improvement in muscular endurance, while the subjects in the aerobic exercise condition experienced improvement in cardiovascular health.
