Protein is well known for it’s role in post-exercise recovery, from aiding muscle growth and repair, to reducing muscle soreness. But did you know that it’s not just what you eat — timing matters too.
In this blog, we explore the importance of protein in post-exercise nutrition, and explain how and when protein should be consumed, particularly around exercise to optimise recovery and performance, for both men and women.
Protein metabolism is a crucial component of how our bodies repair and build muscle tissue, especially following exercise. However, recent research highlights that men and women have different protein requirements.
One of the key distinctions lies in how each sex oxidizes protein and leucine, a branch chain amino acid pivotal for triggering muscle protein synthesis. Studies suggest that women within their reproductive years typically oxidize less protein and leucine compared to men, which can influence how efficiently they recover from physical exertion.
These differences are rooted in the metabolic processes occurring in the liver. For both sexes, protein is vital for muscle adaptation and immune function post-exercise.
However, the distinct metabolic pathways and hormonal influences in women necessitate a closer look at how and when protein should be consumed particularly around exercise to maximize benefits.
Hormones play a significant role in how the body responds to protein intake and exercise. For women, the fluctuating levels of oestrogen and progesterone throughout the menstrual cycle introduce additional variables.
Oestrogen, often elevated during certain phases of the cycle, is known to inhibit muscle protein synthesis. Conversely, high levels of progesterone can enhance muscle breakdown, complicating the recovery process after workouts particularly if a women is training in a fasted state.
In men, the hormonal landscape is more stable, allowing for a more consistent approach to protein metabolism and muscle repair. This hormonal stability generally translates to a less critical timing for protein intake post-exercise.
However, for women, understanding the interplay of hormones and their impact on muscle recovery is essential for optimising post-exercise nutrition and preventing lean muscle loss.
The menstrual cycle can greatly influence how women should approach their post-exercise recovery. During the high hormone phases, when oestrogen levels peak, women may experience reduced efficiency in muscle protein synthesis. This reduced efficiency means recovery nutrition must be done quickly post training to prevent lean muscle loss.
After exercise the body is most primed to utilise nutrients it receives for repair and restoration. Its recommended to eat 20 – 25g of protein and 40 – 60g of carbohydrate within the hour post training. Men have a wider window for recovery of 3 – 4 hours.
Not meeting recovery recommendations for both sexes will have a negative impact not only on recovery, energy levels, body composition but also immune function as well.
Women looking to enhance their muscle recovery should focus on a few practical strategies.
Track it. There are many apps out there that help you such as Flo or Wild Ai. By tracking your cycle you will gain insight into your hormonal phases – which will allow you to prioritise your nutrition accordingly. For example, during the high hormone phases, ensuring that you consume include a recovery snack or meal within the hour post training can counteract hormonal impacts on muscle synthesis.
Such as eggs, Greek yogurt, tofu, edamame beans chicken or fish post-training. However, don’t forget the benefits of the other nutrients as well! Carbohydrates are needed for optimal recovery and to support your immune system. Healthy fats, vitamins and minerals from fruit and vegetables also support overall recovery.
These are also essential components of a comprehensive recovery strategy. By combining these practical tips with a focus on timely protein intake, women can optimise their post-exercise recovery and improve their athletic performance.
Protein plays an essential role in post-workout recovery for both men and women alike, from helping to repair and build muscle, to reducing soreness. By focusing on timely protein intake and understanding how this differs between men and women, you can use nutrition to enhance your performance and overall well-being.
