As we age, our bodies feel heavier and our stamina drops. Do you know which part of our body wastes away first?
It is the ‘thigh muscle’, the massive pillar and measure of our health.
Many people focus only on their upper body or belly fat when trying to diet or manage their health.
However, to protect our centenarian health and prevent terrifying chronic diseases like diabetes, heart disease, and arthritis, we must focus above all on our lower body muscles, especially our thighs.
In today’s post, let’s take a closer look at why thigh muscles play such a decisive role in our bodies.
1. Why Thigh Muscles Are Important for Our Body
- The Ultimate ‘Fat-Burning Bucket’: Among all the muscles in our bodies, the thigh muscles account for nearly 30% of total muscle mass, making them the largest muscle group.
- Unlike smaller muscles like the arms or abdomen, building large muscles like the thighs increases our basal metabolic rate, allowing us to burn more calories and fat efficiently.
- The Core of Walking and Fall Prevention: When analyzing muscle waveforms during walking, the quadriceps (the muscles on the front of the thighs) play the most important role. If lower body strength and thigh power are lacking, people easily trip even over minor impacts, which can lead to major fall accidents like hip fractures.
2. The Deep Connection Between Thigh Muscles and Chronic Diseases
① Diabetes Prevention and Control
The carbohydrates we consume are converted into glucose to be used as energy, and insulin acts to move this glucose into muscle cells.
- The greater the muscle mass, the more active glucose metabolism becomes, and thigh muscles consume a large amount of glucose, which greatly helps control blood sugar.
- Conversely, when thigh muscles shrink and fat accumulates, inflammatory substances from the fat increase insulin resistance, having a devastating adverse effect on diabetes control.
② Reduced Risk of Cardiovascular Disease
Due to aging, when thigh muscles shrink and fat fills their place, inflammatory responses within the muscles rise.
These inflammatory substances destroy vascular endothelial cells and block blood vessels, which triggers critical diseases such as myocardial infarction and cerebral infarction.
In fact, research shows that even without hypertension or diabetes, the presence of sarcopenia (muscle loss) increases the risk of cardiovascular disease by 76%.
③ Alleviation of Knee Arthritis Pain
Many people worry, “Can I still exercise if my joints hurt?” Knee joints are supported together by muscles and ligaments, and when thigh muscles are strong, the muscles themselves absorb external shocks and loads heading toward the joints. Therefore, building thigh strength greatly helps reduce arthritis pain and lowers the probability of surgery.
3. Lower Body Strengthening Exercises Possible Even in Your 70s and 80s
As we age, thigh muscles naturally decrease every year starting from our 40s, but through consistent strength training, there are cases where people in their 70s and 80s regained strength comparable to people in their 30s to 50s. Representative lower body exercises that are good to practice in daily life include:
- Cycling (Indoor and Outdoor Cycling): The ultimate exercise that uses both the front and back muscles of the thighs to build lower body strength while minimizing strain on the knees.
- In-line Skating: Effectively builds balance and lower body strength simultaneously, making it effective for preventing falls in the elderly.
- Leg Raises While Seated & Light Squats/Tai Chi Postures: Even elderly individuals or patients with weak joints can safely build thigh power through actions such as lifting and lowering legs while sitting in a chair, or bending their knees slightly and holding the posture.
💡 Conclusion
“Having strong thighs means having a healthy body.
Just as we save money to prepare for old age, building our body’s muscles to prepare for our later years is just as important.”
Rather than staying away from exercise because of advanced age, try consistently practicing appropriate lower body exercises suited to your physical condition to protect your firm thighs and prepare for a vibrant, centenarian life!
