Muscles are divided into two categories: fast twitch and slow twitch. Fast twitch fibers, or type II muscle, generate energy 10 times faster than slow twitch fibers, but tire quickly due to anaerobic metabolism. Lactic acid is a reserve fuel, but can cause fatigue. More muscular athletes have a greater distribution of fast-twitch muscle fibers, […]
Slow twitch muscle fibers provide endurance for activities like running and cycling, while fast twitch fibers produce more power but fatigue quickly. Slow twitch fibers use oxygen more efficiently to generate energy, making them better suited for aerobic exercise. Strength training can target different types of fibers, with more reps and lower weights engaging slow […]
Dietary fiber, found in plant foods, is largely indigestible and contributes few calories or nutrients. It improves digestive function, bowel movements, and colon health, and can lower cholesterol and stabilize blood sugar levels. Soluble fiber delays nutrient absorption and lowers cholesterol, while insoluble fiber adds bulk to stool and improves colon function. Dietary fiber is […]
Type I muscle fibers are used for long-duration, low-intensity movements, while Type II fibers are used for short-duration, high-intensity movements. Type I fibers are red in appearance, have more myoglobin and are more suitable for aerobic activity, while Type II fibers are white in appearance, have no myoglobin and rely on glycolytic enzymes for energy. […]
Scientists have created a synthetic spider silk that is 98% water and has super-strong fibers, similar to the real thing. The fibers are spun from a hydrogel mixture and can be used in applications such as bulletproof vests and helmets. Spider silk is one of the strongest materials in nature. It also has a high […]
