Discomfort during exercise?


Hello, Doctor: During high school, I rarely exercised except for physical education classes, and I walked less than 30 minutes each day, although I occasionally went jogging or hiking.
Given my lack of exercise in high school, I have recently started dedicating a lot of time to working out since the beginning of university and am trying to establish a routine.
Last week, I cycled for a total of 1 to 2 hours and walked 6 kilometers (the first two activities were concentrated from Monday to Wednesday), and I planned to run 7 kilometers on Friday afternoon.
However, during the 7-kilometer run, I sometimes walked in the beginning and almost walked the last kilometer.
I did not feel uncomfortable while running or after, and my legs were hardly sore.
This week, it seems I have exercised even more: in addition to walking around the large campus while going to class, I also cycled for 1 to 2 hours each day.
This Friday, I want to run the same 7-kilometer route again, but this time, I felt soreness in my legs and pain in my lower abdomen (similar to menstrual cramps) after running less than 100 meters (at a slow pace), and I also felt very breathless and tired, so I ended up walking the rest of the way, which I completed without discomfort.
Am I experiencing this because I suddenly increased my exercise too much, or could it be related to premenstrual syndrome? Should I see a doctor? (I heard that some people noticed a decline in their physical condition during exercise and later found out they had cancer, which makes me very worried...) Is it bad that I suddenly increased my exercise volume so much? Thank you, Doctor, for taking the time to respond!

It is recommended to gradually increase the amount of exercise rather than making a sudden significant increase.
Currently, it is advisable to reduce activity and rest.
Once symptoms subside, you can slowly increase the activity level.
If symptoms persist, further evaluation may be necessary.

Understanding exercise discomfort is crucial for anyone engaging in a new or intensified fitness routine, especially after a period of inactivity. It’s commendable that you are taking steps to improve your physical fitness by incorporating more exercise into your daily routine. However, it’s important to listen to your body and recognize when discomfort may signal a need for medical advice.

From your description, it seems that you have significantly increased your physical activity levels in a short period. Transitioning from minimal exercise to several hours of biking and running each week can put a strain on your body, especially if you haven't built up your endurance gradually. The discomfort you experienced during your recent run, particularly the pain in your lower abdomen and fatigue, could be attributed to several factors.

Firstly, it’s possible that you are experiencing delayed onset muscle soreness (DOMS), which is common when starting a new exercise regimen or increasing intensity. This soreness typically occurs 24 to 48 hours after exercise and can be accompanied by feelings of fatigue. However, the specific pain you described in your lower abdomen, akin to menstrual cramps, could also be related to other factors, such as premenstrual syndrome (PMS) or even gastrointestinal discomfort, especially if you were running on a full stomach or had not adequately hydrated.

Another consideration is the risk of overtraining. When you suddenly increase your exercise volume without allowing your body sufficient time to adapt, you may experience symptoms of overtraining, which can include fatigue, decreased performance, and increased susceptibility to injury. It’s essential to incorporate rest days into your routine and allow your body to recover, especially after intense workouts.

Regarding your concern about serious health issues, such as cancer, it’s understandable to feel anxious, especially when hearing stories of others who have faced severe health challenges. However, it’s important to remember that exercise discomfort is often benign and can be attributed to the body adjusting to new demands. If you experience persistent pain, unusual symptoms, or if the discomfort worsens, it would be wise to consult a healthcare professional for a thorough evaluation.

In the meantime, consider the following recommendations:
1. Gradual Increase: Gradually increase your exercise intensity and duration. Instead of jumping into longer runs, consider incorporating interval training or shorter runs with walking breaks to build your endurance without overwhelming your body.

2. Cross-Training: Engage in a variety of activities to prevent overuse injuries. Cycling, swimming, and strength training can complement your running and provide a balanced fitness regimen.

3. Listen to Your Body: Pay attention to how your body responds to exercise. If you feel pain that is sharp or persistent, it’s important to stop and assess the situation. Rest is crucial for recovery.

4. Hydration and Nutrition: Ensure you are well-hydrated and consuming a balanced diet to support your increased activity levels. Proper nutrition can help with recovery and overall performance.

5. Consult a Professional: If your symptoms persist or you have concerns about your health, don’t hesitate to seek medical advice. A healthcare provider can help rule out any underlying conditions and provide personalized recommendations.

In conclusion, while it’s great that you are motivated to improve your fitness, it’s essential to approach your new routine with caution and mindfulness. By gradually increasing your activity levels, listening to your body, and seeking medical advice when necessary, you can enjoy the benefits of exercise while minimizing the risk of injury or discomfort.
