Introduction
School physical education programs play a crucial role in the lives of adolescents, not only significantly impacting physical health but also positively influencing posture and overall development.Physical exercise not only contributes to maintaining a healthy weight and cardiovascular health but also helps improve musculoskeletal health and prevent issues like fractures.Furthermore, school physical education programs provide opportunities to enhance posture, shape correct posture, and achieve proper body proportions.However, the actual effectiveness and current status of school physical education programs vary across regions and schools, necessitating in-depth assessment and optimization.

Promoting Cardiovascular Health
School physical education programs typically include aerobic exercises such as running, swimming, and basketball, which help improve heart health.Research has shown that aerobic exercise increases heart endurance and reduces the risk of heart disease.For instance, a long-term study found that adolescents participating in physical activities had a lower incidence of heart disease in adulthood.Furthermore, physical exercise helps lower the risk of high blood pressure, a major cardiovascular disease risk factor.Adolescents exercising in physical education classes can help maintain healthy blood pressure levels.According to the American Heart Association, engaging in at least 150 minutes of moderate-intensity aerobic exercise per week or 75 minutes of high-intensity aerobic exercise significantly reduces the risk of heart disease and stroke.Physical education programs also contribute to improving the circulatory system of adolescents.[1] Aerobic exercise makes the heart pump blood more efficiently, improving blood flow and reducing the burden on the heart.Enhanced blood circulation ensures the effective delivery of oxygen and nutrients to various parts of the body while helping remove waste and toxins.Additionally, physical exercise helps lower levels of bad cholesterol in the blood, which is crucial for cardiovascular health.Research has found that aerobic exercise increases high-density lipoprotein cholesterol levels while lowering low-density lipoprotein cholesterol levels.[2]

Enhancing Musculoskeletal Health
Physical exercise, especially resistance and weight-bearing training, helps increase muscle mass.These exercises encourage more involvement of muscles, thereby enhancing the quantity and quality of muscle fibers.Studies have shown that moderate resistance training significantly improves the muscle mass of adolescents.A study found that adolescents engaging in six months of resistance training showed significant improvements in muscle mass, indicating that exercise can effectively increase muscle.Increasing bone density is also crucial for physical exercise.Repeated impact and weight-bearing activities stimulate bone growth and increase bone density.This is especially important for adolescents as their bones are still developing.Multiple studies have found that adolescents participating in aerobic exercises, jumping activities, and resistance training have higher bone density, particularly during the period of bone growth, and this effect is particularly significant.By improving muscle mass and bone density, physical exercise significantly reduces the risk of fractures.Adolescents with strong muscles and sturdy bones are more resistant to fractures in case of injury.Research shows that adolescents participating in physical exercise have a lower probability of fractures, especially compared to their peers who do not exercise or engage in less physical activity.

Weight and Body Fat Management
School physical education programs typically encompass various aerobic exercises that help adolescents burn calories and maintain a healthy weight.Additionally, aerobic exercise can increase the basal metabolic rate, making the body more efficient at energy expenditure.A study found that adolescents engaged in physical activities were more likely to maintain a healthy weight compared to their peers who did not participate in physical activities.This suggests that physical education programs play a positive role in helping adolescents manage their weight.Controlling body fat is equally important, and physical exercise contributes to body fat control.Through aerobic exercise and resistance training, adolescents can improve their body fat levels and reduce unhealthy fat accumulation.[3] This is crucial for preventing obesity and related health issues.Multiple studies have demonstrated that adolescents participating in physical exercise generally have lower body fat levels, making it easier for them to maintain healthy body fat levels compared to adolescents who do not exercise or engage in minimal physical activity.Physical activity also improves the mental health of adolescents, helping control weight and body fat.Exercise can reduce anxiety and depression, which helps avoid emotional eating and unhealthy dietary choices, aiding in weight and body fat control.School physical education programs have a positive impact on weight management and body fat control for adolescents.By providing case studies and empirical data, we can observe the actual evidence of these effects, emphasizing the crucial role of physical education programs in helping adolescents maintain a healthy weight and body fat level.[4]

Improving Posture
Proper posture is crucial for both physical health and appearance.Poor posture not only affects one's external appearance but can also lead to a range of health issues.For example, rounded shoulders, hunching, and forward leaning can result in discomfort, muscle tension, and pain in the back and neck.Additionally, incorrect posture can impact respiratory efficiency and digestive system function.School physical education programs provide an ideal environment for students to learn and practice proper posture.Coaches and educators guide students on how to stand, walk, sit, and perform various sports activities with correct posture.This includes details like maintaining body balance, keeping the spine straight, and relaxing the shoulders.Proper posture can alleviate discomfort in the back and neck, reducing the risk of muscle tension and pain.It also aids in expanding the lungs, improving respiratory efficiency, and increasing oxygen supply.Good body posture can boost students' confidence.Their appearance becomes more attractive, contributing to enhanced self-esteem and self-confidence.Proper posture helps prevent posture-related health issues such as hunching and rounded shoulders.Improving posture not only benefits physical health but also enhances personal image and self-assurance.School physical education programs provide an ideal platform for adolescents to learn, practice, and reinforce correct posture habits, which is essential for their future health and quality of life.[5]

Enhancing Body Proportions
The diversity of activities in school physical education programs encompasses various types of exercises, including aerobic activities, strength training, and flexibility exercises, which contribute to shaping healthy body proportions.Aerobic exercises such as jogging, swimming, and jumping rope can effectively reduce unnecessary body fat.These exercises burn a significant number of calories, helping to sculpt a leaner body proportion.Aerobic exercises also improve cardiovascular fitness, enabling the heart to pump blood more efficiently and the lungs to deliver oxygen more effectively.This not only enhances body posture but also provides increased endurance.Strength training exercises such as weightlifting and gymnastics can significantly increase muscle mass.This aids in sculpting the body's lines and curves, improving muscle proportions.Muscles consume more calories than fat, so increasing muscle mass helps raise the basal metabolic rate.This means the body burns more energy even at rest.Flexibility exercises like yoga and stretching can increase joint flexibility, making the body more supple.This contributes to improving the fluidity and comfort of body posture.Combining these different exercise forms helps students shape healthier and more attractive body proportions.These exercises not only have a positive impact on appearance but also enhance overall physical functionality and health.Through school physical education programs, students have the opportunity to engage in these diverse exercise modalities, assisting them in shaping better body proportions and improving their overall physical fitness.This benefits not only their external image but also supports the maintenance of physical health and functionality.[6]
