Final answer:
Flexibility exercises are the recommended type of exercise for addressing overactive, shortened hamstrings because they stretch and lengthen the muscles, improving range of motion and preventing injury.
Step-by-step explanation:
To address overactive, shortened hamstrings, the type of exercise recommended is flexibility exercises. This form of physical activity focuses on stretching and lengthening muscles, which is essential for increasing the range of motion and preventing injury due to tight muscles. Flexibility exercises include activities like stretching, yoga, and tai chi, which can help alleviate the tightness in the hamstrings and enhance overall muscle balance.
Consistently incorporating these exercises into one's routine can lead to significant improvements in flexibility, allowing for greater ease of movement and a reduced risk of strains and other muscle-related injuries. These exercises serve as an effective method to counteract the negative effects associated with overactive, shortened muscles such as the hamstrings.
