For female athletes, the menstrual cycle is more than just a monthly occurrence—it can significantly impact performance, recovery, and overall well-being. While each woman experiences her cycle differently, fluctuations in hormones throughout the month can influence strength, endurance, energy levels, and even the risk of injury. Understanding these effects can help athletes and coaches better manage training and competition schedules for optimal performance (Baker & Jeukendrup, 2014; Sung & Kim, 2020).
Phases of the Menstrual Cycle and Their Impact on Performance
The menstrual cycle typically lasts around 28 days and consists of four main phases, each of which affects the body in different ways (Kowalski & Rea, 2016).
1. Menstrual Phase (Days 1-5)
This phase begins when hormone levels drop, causing the uterine lining to shed. Many athletes experience fatigue, cramps, and a decrease in strength due to lower oestrogen and progesterone levels (Sung & Kim, 2020).
While some may feel sluggish, others find light exercise helps alleviate symptoms by increasing blood flow and releasing endorphins (Patterson & Stock, 2018).
2. Follicular Phase (Days 6-14)
Oestrogen levels begin to rise, promoting increased energy and endurance (Zabinski & Thomas, 2021).
Strength and performance typically peak due to improved muscle recovery and metabolism (Baker & Jeukendrup, 2014).
Many female athletes find this phase to be the best time for high-intensity training and strength-based workouts (Hawkins & Wiswell, 2003).
3. Ovulation Phase (Around Day 14)
Oestrogen reaches its highest point, and testosterone also spikes, which may lead to increased power and motivation (Kowalski & Rea, 2016).
However, some women may experience bloating or discomfort, and studies suggest a higher risk of ligament injuries (e.g., ACL tears) due to increased joint laxity (Baker & Jeukendrup, 2014; Patterson & Stock, 2018).
4. Luteal Phase (Days 15-28)
Progesterone levels rise, which can lead to water retention, mood changes, and a decrease in energy (Zabinski & Thomas, 2021).
Some athletes report feeling more fatigued, with a reduced ability to recover from intense training (Sung & Kim, 2020).
Body temperature is slightly higher, which may impact endurance and thermoregulation, making it harder to perform in hot conditions (Lloyd & McNulty, 2019).
Managing Training and Performance Around the Menstrual Cycle
Tracking the Cycle – Using apps or journals to monitor symptoms and energy levels can help identify patterns and adjust training accordingly (Lloyd & McNulty, 2019).
Adjusting Training Loads – High-intensity training can be maximised during the follicular phase, while the luteal and menstrual phases may require more emphasis on recovery and mobility work (Hawkins & Wiswell, 2003).
Nutrition and Hydration – Eating iron-rich foods, staying hydrated, and maintaining a balanced diet can help combat fatigue and inflammation (Patterson & Stock, 2018).
Recovery Strategies – Prioritising sleep, active recovery, and stress management can improve overall well-being throughout the cycle (Kowalski & Rea, 2016).
Communication – Athletes should feel comfortable discussing menstrual health with coaches and medical staff to create individualised training plans (Sung & Kim, 2020).
Breaking the Stigma
Despite its significant impact, menstruation remains an under-discussed topic in sports. By normalising conversations about the menstrual cycle, we can ensure female athletes receive the support they need to perform at their best. Understanding how hormones influence physical performance allows for smarter training strategies, ultimately leading to improved results and overall athlete well-being (Zabinski & Thomas, 2021).
In the end, the menstrual cycle should not be seen as a limitation but as an essential part of an athlete’s physiology that, when managed effectively, can contribute to long-term success in sports (Baker & Jeukendrup, 2014; Lloyd & McNulty, 2019).
