Infrequent participation in physical activity can lead to
A high blood pressure during exercise
B muscle strain and soreness after exercise
C extra calories burned during exercise
D low heart rate after exercise
The Correct Answer and Explanation is :
The correct answer is B. muscle strain and soreness after exercise.
When someone engages in physical activity infrequently or irregularly, their muscles and joints are not as well conditioned to handle the exertion. As a result, the muscles are more susceptible to strain, and delayed-onset muscle soreness (DOMS) can occur. DOMS is the discomfort or pain that sets in 12 to 24 hours after physical activity, peaking around 24 to 72 hours post-exercise.
Why muscle strain and soreness happen:
- Muscle conditioning: Regular exercise improves the strength, flexibility, and endurance of muscles. However, when someone exercises sporadically, their muscles are not well-prepared for the physical demands, which leads to microscopic tears in muscle fibers during activities like lifting weights or running. The body responds to these tears with inflammation, which triggers soreness and discomfort.
- Lack of proper warm-up or cool-down: Those who don’t exercise regularly might skip crucial steps like warming up or cooling down, both of which are important for preventing muscle injury. A proper warm-up increases blood flow and prepares muscles for the upcoming physical strain, while a cool-down helps muscles recover post-exercise.
- Overexertion: When someone who doesn’t exercise regularly engages in physical activity, they might push their body beyond its limits without realizing it. This overexertion can increase the risk of muscle strain, where the fibers stretch or tear.
Infrequent participation in physical activity can also increase the risk of injury to joints, tendons, and ligaments, as these structures are not conditioned for regular movement. Staying consistent with physical activity, gradually increasing intensity, and ensuring proper recovery can help prevent muscle strain and soreness.
