Oxidative Stress and Sports

 Oxidative stress occurs when there is an imbalance in the body between free radicals and antioxidants. Free radicals are molecules with unpaired electrons, which makes them unstable and reactive. When free radicals are high and antioxidants are too low, oxidative stress can damage cells, proteins, and DNA. In athletes and people who exercise regularly, oxidative stress can increase due to intense physical activity. But this is not always negative, as oxidative stress can also signal the body to improve its defenses.

How Exercise Causes Oxidative Stress

Exercise increases oxygen consumption in muscles, which can produce more free radicals. This is especially true for high-intensity or endurance sports. However, the body responds by creating more antioxidants. Regular training can improve this balance, making athletes better at managing oxidative stress over time. But too much exercise or inadequate recovery can lead to chronic oxidative stress, which may slow recovery and increase injury risk.

How to Reduce Oxidative Stress in Athletes

1. Antioxidant-Rich Diet: Eating fruits and vegetables with high antioxidants, like berries, citrus fruits, and leafy greens, helps balance free radicals.
2. Proper Rest and Recovery: Giving the body time to rest is essential for reducing oxidative stress and allowing muscles to repair.
3. Balanced Training: Avoiding overtraining and incorporating rest days can help manage oxidative stress.
4. Hydration and Supplements: Staying hydrated and, if needed, using antioxidant supplements (like vitamin C or E) can aid in controlling oxidative stress.

Conclusion

Oxidative stress is a natural result of exercise, but the key is balance. With a healthy diet, good recovery habits, and moderate training, athletes can minimize the negative effects of oxidative stress and even use it to strengthen their body.

Using Ankle and Wrist Weights: Benefits and Cautions

 Ankle and wrist weights can add intensity to exercises and help you get stronger, but it’s important to know how and when to use them to avoid risks.

Benefits of Ankle and Wrist Weights

These weights add a bit of extra weight to your body during exercises, which makes your muscles work harder. This can help strengthen muscles in your legs, arms, and shoulders. For athletes, these weights can improve power and endurance in specific sports like baseball or tennis. Plus, they help burn extra calories, so some people use them in strength training or light cardio​

Things to Keep in Mind

Choosing the right weight is important. Experts recommend using 0.5 to 2 kg for ankles and 0.5 to 1.5 kg for wrists. Avoid using heavy weights because they can hurt your joints (ankles, knees, and wrists). Ankle weights are usually not recommended for running or walking, as they add too much pressure on your joints. People with past injuries should be especially careful, as the extra weight can cause pain or injury​

Summary

Ankle and wrist weights can make strength and light cardio exercises more effective, but they should be used carefully. Start with light weights and avoid high-impact activities or long use.
