In the quest for fitness and well-being, it's common for women to push themselves hard in the gym, sometimes training every day. However, there's a fine line between dedication and overtraining, and crossing it can have detrimental effects on hormones, weight loss, stress levels, and overall health. In this blog, we'll delve into the world of overtraining and its specific implications for women. We'll also discuss the ideal training frequency, intensity, and timing during different stages of life and the menstrual cycle.
Growth Occurs During the RECOVERY Phase
Understanding supercompensation is crucial for achieving progress without overtraining. A study published in "Sports Medicine" (2015) explains that muscle adaptation and growth occur during the recovery phase, not during the workout. The basic principle is that after you challenge your body with exercise, it temporarily weakens, but with adequate rest and recovery, it rebounds and becomes stronger than it was before.
The Workout: During a workout, especially one that challenges your body, you create stress and fatigue in your muscles and body systems. For example, when lifting weights, you cause micro-damage to muscle fibers.
Initial Recovery Phase: After exercise, your body enters an initial recovery phase. This phase is marked by rest, rehydration, and refueling with nutrients. During this time, the body starts repairing the damage caused during the workout. It begins to restore glycogen stores, repair muscle tissue, and eliminate waste products like lactic acid.
Supercompensation Phase: The supercompensation phase occurs after the initial recovery phase. This is when the body not only fully repairs the damage but also adapts to handle a similar stressor more effectively in the future. Muscle fibers become denser and stronger, and energy storage capacity increases. This is where the real gains in fitness, strength, and endurance occur.
Hormonal Havoc: The Perils of Overtraining
Hormones play a central role in the body's response to exercise and recovery. After intense physical activity, the body experiences a surge in stress hormones like cortisol. While cortisol is essential for regulating various bodily functions, excessive or prolonged elevation, as seen in overtraining, can disrupt hormonal balance. A study published in the "Journal of Sports Science & Medicine" (2016) found that excessive exercise can lead to chronically elevated cortisol levels. This chronic elevation can result in a condition known as "exercise-induced hypothalamic amenorrhea,". The excessive stress placed on the body can disrupt the hypothalamus-pituitary-ovarian axis, affecting the production of estrogen and progesterone. Irregular periods or amenorrhea can lead to fertility issues and reduced bone density, increasing the risk of osteoporosis.
The disruption of these hormones can also increase the risk of anxiety and depression, mood swings, fatigue, PMS, sleeping problems, weight gain, injury risk, reduced bone density, heavy periods, vaginal dryness and dry skin.
Moreover, the Women's Health Initiative Observational Study (2002) revealed that women who engaged in high levels of physical activity had a 34% lower chance of regular menstrual cycling compared to women with lower activity levels.
Prioritise Recovery after Menopause
Cardiovascular health becomes increasingly important during menopause. Estrogen, which declines during this time, has a protective effect on the cardiovascular system. Exercise can help maintain heart health, but overtraining can stress the heart and counteract these benefits. It's crucial to find a balance that supports cardiovascular fitness without overloading the system.
Many menopausal women experience hot flashes and sleep disturbances. Overtraining can exacerbate these symptoms due to increased body temperature and disrupted sleep patterns. Tailoring exercise intensity and timing to avoid overheating and prioritizing good sleep hygiene are essential.
Weight Woes: Overtraining's Hindrance to Weight Loss
The relationship between overtraining and weight loss is complex. Although exercise is essential for weight management, overtraining can have the opposite effect. Excessive exercise can lead to elevated cortisol levels, which promote fat storage, particularly around the abdominal area. A study published in the "Journal of Sports Science & Medicine" (2012) found that high training volumes, typical of overtraining, are associated with increased cortisol levels and reduced fat loss.
Furthermore, the disruption of hunger hormones, such as leptin and ghrelin, due to overtraining can lead to increased appetite and a propensity to overeat, counteracting weight loss efforts.
Stressing Out: The Mental Toll of Overtraining
The mental toll of overtraining should not be underestimated. A study in the "Journal of Sports Sciences" (2004) reported that overtrained athletes often experience mood disturbances, anxiety, and increased perceived stress levels. This emotional and psychological stress can lead to burnout and negatively affect overall well-being.
Optimal Recovery Period for Different Workout Intensities:
Low to Moderate-Intensity Workouts (e.g., steady-state cardio, moderate weight lifting):
For low to moderate-intensity workouts, women typically require 24 to 48 hours of recovery time between sessions targeting the same muscle groups. This allows for muscle repair and adaptation without risking overtraining.
High-Intensity Interval Training (HIIT):
HIIT is more intense and places greater stress on the body. As a general guideline, women should allow at least 48-72 hours of recovery between high-intensity sessions targeting the same muscle groups. True HIIT sessions are performed at maximal intensity, which is extremely difficult to do for extended periods of time, and requires a long time to recover from. HIIT should be limited to 1-2 times per week, with 48 to 72 hours of recovery between sessions, and for no longer than 10-20 minutes each session.
Strength Training with Heavy Weights:
Strength training with heavy weights can cause muscle damage that requires slightly longer recovery periods. Women should aim for 48 hours of recovery between sessions that focus on the same muscle groups.
Super-Intense or Advanced Workouts (e.g., CrossFit, Powerlifting):
For extremely intense workouts or advanced training regimens, recovery time may need to be extended to 72 hours or more. It's crucial to listen to your body and adjust your training frequency accordingly to prevent overtraining.
Recovery Throughout the Menstrual Cycle & Menopause
The menstrual cycle is divided into four phases: menstruation, the follicular phase, ovulation, and the luteal phase. Hormonal fluctuations occur throughout this cycle, influencing a woman's physical and emotional state. Tailoring your exercise and recovery routine to these hormonal changes can optimize performance and overall well-being.
Follicular Phase
This phase is ideal for increasing training intensity. Recovery should still include rest days, but you'll likely feel more energetic. Optimal training frequency is 4-5 days of moderate-intensity training focusing on Strength Training, Cardiovascular Workouts, and Mobility.
Ovulation
This is the best time for intense workouts and pushing your limits. Recovery should include adequate sleep and nutrition to support the increased energy expenditure. Training frequency can be increased with higher recovery, aiming for 4-6 days per week of a combined HIIT, Heavy Weight Training & Hypertrophy style workouts.
Luteal Phase
As hormonal fluctuations may cause mood disturbances and fatigue, focus on workouts that support mental well-being and perform 3-4 days per week of Yoga, Pilates, Light Weight Training or Moderate-Intensity Cardio. Recovery is essential to manage stress.
Menses
This is a time for gentle movement and recovery. Your body is likely to be fatigued, and you may experience discomfort. Focus on restorative practices like Yoga, Stretching, and Walking. Hydration and nutrition are crucial to support your body through this phase. Optimal training frequency is 2-3 days per week to allow for adequate recovery.
Peri-Menopause
During this phase, which can last several years, you might experience irregular periods and hormonal fluctuations. Prioritise rest and relaxation as your body adapts to changing hormone levels. Focus on low to moderate-intensity activities 3-4 days per week of Light Weight Training, Pilates, Yoga, and Walking. These exercises can help manage stress, prevent muscle loss and support joint flexibility.
Menopause
Menopause officially begins when you've gone 12 months without a menstrual period. Your hormone levels have significantly decreased, and recovery becomes even more critical. Continue with low to moderate-intensity exercises, emphasizing Strength Training, Cardiovascular Fitness, Walking and Flexibility. Recovery days should be included to ensure your body has time to repair and adapt but training 3-5 days per week is optimal.
Remember that individual factors, including fitness level, age, and overall health, can influence recovery times. Additionally, nutrition, sleep, and stress management play vital roles in the recovery process. Pay attention to your body's signals, such as soreness, fatigue, and reduced performance, and adjust your training frequency and intensity accordingly.
It's also important to periodise your training, which involves varying the intensity and volume of your workouts over time. This helps prevent overtraining and promotes continuous progress by allowing different muscle groups to recover while others are being targeted.
Ultimately, finding the right balance between training and recovery is essential for women to maximise their fitness gains, minimise the risk of injury, and support long-term health and wellness goals.
