Daisy has added rowing and running to her fitness routine. These activities are MOST LIKELY going to improve her.
A. Body Composition
B. Muscle Fitness
C. Cardiovascular Fitness
D. Flexibility
The Correct Answer and Explanation is:
Correct Answer: C. Cardiovascular Fitness
Rowing and running are both aerobic exercises that primarily target cardiovascular endurance. These types of activities increase heart rate for a sustained period, promoting stronger heart function, improved lung capacity, and more efficient oxygen delivery throughout the body. As Daisy engages regularly in rowing and running, her heart becomes more efficient at pumping blood, and her body becomes better at using oxygen to fuel physical activity. This leads to improved cardiovascular fitness.
Cardiovascular fitness refers to the ability of the heart, lungs, and circulatory system to supply oxygen to working muscles during prolonged physical activity. Rowing and running require the body to work continuously and rhythmically, which enhances the endurance of these systems. Over time, individuals who consistently perform aerobic exercises notice they can perform the same activities with less effort, showing improvements in stamina and reduced fatigue.
While rowing and running do involve muscles in the arms, legs, and core, they are not the most effective exercises for significantly building muscular strength or size. Therefore, they have limited effects on muscle fitness, which refers to strength and muscular endurance. These activities also have minimal impact on flexibility, which is the range of motion around a joint, and any improvements in body composition (such as fat loss or muscle gain) are secondary benefits and often depend on other factors like diet and resistance training.
In summary, the main benefit Daisy will gain from consistently performing rowing and running is enhanced cardiovascular fitness. These activities strengthen the heart and lungs, boost endurance, and help the body use energy more efficiently during exercise and daily life.
