Optimising your fitness journey goes beyond just hitting the gym. Proper nutrition plays a crucial role, impacting both pre- and post-workout performance and recovery. However, numerous myths and misconceptions cloud this topic, often leading to suboptimal results.

This article debunks these common myths and provides evidence-based information to fuel your body for peak performance and optimal recovery.

Pre-Workout Nutrition Myths

Myth 1: Eating before a workout will divert blood flow away from muscles.

This widespread myth lacks truth. In reality, consuming carbohydrates before a workout enhances blood flow and nutrient delivery directly to working muscles.

A 2011 study published in the Journal of Sports Science and Medicine found that pre-workout carbohydrate intake leads to better performance and endurance [1].

Myth 2: Avoiding carbohydrates before a workout will burn more fat.

While fat burning occurs during exercise, depleting carbohydrate stores doesn’t maximise it. According to Vigh-Larsen et. al. (2021), carbohydrates are the primary fuel source for high-intensity exercise, and neglecting them can lead to fatigue, decreased performance, and hinder your workout goals [2].

Myth 3: Pre-workout supplements are essential for a good workout.

Pre-workout supplements are often marketed as a magic bullet for enhanced performance. However, the evidence is mixed.

A 2017 study published in the Journal of the International Society of Sports Nutrition concluded that pre-workout supplements do not improve exercise performance but they may improve energy and focus [3].

Pre-Workout Recommendations

  • 2-3 hours before your workout: Consume a balanced meal or snack rich in carbohydrates and protein for optimal energy and performance.
  • Choose easily digestible carbohydrates: Opt for fruits, vegetables, whole grains, and yogurt.
  • Tailor your pre-workout meal size: Adjust based on your activity level and individual needs.

Post-Workout Nutrition Myths

Myth 1: You have a 30-minute window to replenish glycogen after your workout.

This myth holds some truth, but it’s not the whole picture. While consuming carbohydrates within a few hours after exercise can help maximise glycogen resynthesis, the process continues for several hours.

A 2017 study published in the Applied Journal of Physiology found that glycogen resynthesis continues for up to 24 hours after exercise [4]. This means you have a window of opportunity for optimal recovery, not a strict deadline.

Myth 2: You need a protein shake immediately after a workout to maximise muscle growth.

Protein plays a crucial role in muscle growth and repair, but consuming it immediately after a workout isn’t essential.

Research suggests that protein synthesis remains elevated for several hours after exercise, providing a window for optimal protein intake [5]. This allows for a balanced post-workout meal that includes carbohydrates and healthy fats for overall recovery.

Post-Workout Recommendations

  • Within 2-3 hours after your workout: Consume a balanced meal or snack to optimise recovery.
  • Focus on carbohydrates: Replenish glycogen stores with easily digestible sources like fruits, vegetables, and whole grains.
  • Include protein: Promote muscle repair and growth with a moderate serving.
  • Add healthy fats: Promote satiety and hormone balance with nuts, seeds, avocado, or olive oil.
  • Adjust your post-workout meal size: Tailor it to your activity level and individual needs.

You can now make informed choices for optimal performance and recovery after learning about these pre- and post-workout myths. Individualisation is key so adapt your pre- and post-workout nutrition strategies based on your fitness goals, activity level, and body’s unique requirements.
