Welcome to Fitness Friday! Today, we're diving into the world of amino acids and highlighting one that's crucial for muscle growth—leucine. As Pilates teachers, it's important to understand the role of nutrition in muscle development to better guide our clients.
What is Leucine?
Leucine is an essential branched-chain amino acid (BCAA), which means our bodies can't produce it on their own. We must obtain it through our diet. Research has shown that leucine is particularly vital for building and repairing muscle tissue. It stands out among other BCAAs because it activates the mTOR pathway, which controls muscle protein synthesis (MPS)—the process of creating new muscle.
Why is MPS Important?
Muscle tissue is dynamic, constantly being broken down and rebuilt throughout the day. When MPS exceeds the breakdown rate, muscle growth occurs. Conversely, if the breakdown rate surpasses MPS, we lose valuable lean mass. Maintaining a positive balance of MPS is crucial for not only increasing but also preserving muscle mass.
More muscle mass is associated with a higher metabolic rate, better bone health, and improved insulin sensitivity. It’s even linked to increased longevity. Therefore, ensuring optimal MPS is essential for overall health and well-being.
The Exact Amount of Leucine You Need
To stimulate MPS effectively, you need approximately 2.5 to 3 grams of leucine at each meal. Research indicates that meals containing less than 1.8 grams of leucine don't support MPS adequately.
How to Get Enough Leucine Without Going Crazy
You can achieve this leucine threshold by consuming 20-25 grams of high-quality animal protein or 30-40 grams of plant-based protein per meal. Plant foods naturally contain lower levels of leucine, so you’ll need to consume more to meet the necessary amount.
The goal is to reach this leucine threshold at every meal, not just once a day. Additionally, while protein and leucine are critical for MPS, strength training is the most effective way to initiate this process.
Strength Training and Pilates
On this Fitness Friday, let's focus on the importance of strength training, especially for women. Combining strength training with Pilates can significantly enhance muscle development and overall fitness. Strength training not only builds muscle but also complements Pilates by improving functional strength and stability.
Incorporating both high-quality protein intake and regular strength training into your routine is key to maximising muscle growth and maintaining a healthy, strong body. As Pilates teachers, understanding and sharing this knowledge with your clients can help them achieve their fitness goals more effectively.
Stay strong and keep moving!
