The Impact of Women's Exercise on Endometriosis: A Study on the Benefits for Pain Management

Based on the Journal of Applied Physiology, Medicine & Science in Sports & Exercise, Sports Medicine, British Journal of Sports Medicine, and other international peer-reviewed journals, this article provides an in-depth analysis of the scientific evidence on “exercise and endometriosis” in the field of female exercise physiology. It also incorporates Taiwan’s local climate, race, and sports culture contexts to offer evidence-based training and health strategies.

In the realm of female exercise physiology, “exercise and endometriosis” is a topic with both academic depth and practical value, yet it has long been misunderstood or overlooked. The knowledge accumulated in exercise science over the past decades has largely been based on studies of healthy adult males, meaning that many of the unique physiological characteristics and needs of female exercise physiology have only received systematic attention and research in recent years. In fact, adolescents, women, and special populations (such as older adults, pregnant and postpartum women, and those with chronic illnesses) differ fundamentally from the “standard young male athlete” in terms of physiological structure, hormonal environment, developmental stage, and health context. Directly applying adult male training principles and physiological data to these groups can lead to diminished results at best, and health harm at worst. This is precisely why understanding “exercise and endometriosis” is so important—it allows us to move beyond the “one-size-fits-all” myth and provide scientific guidance that truly aligns with the physiology and needs of different populations. Taiwan is moving toward an aging society, gender equality awareness is rising, and youth sports participation is increasingly common—these trends make the local application of female exercise physiology particularly valuable. This article will take you from cellular and systemic physiological mechanisms, through empirical research in top international journals, the quantitative relationship between dose and effect, differences in responses across populations, to directly actionable training applications and Taiwan’s local context. Finally, we will debunk long-standing myths, so that your understanding of “exercise and endometriosis” is truly built on science, not hearsay or outdated stereotypes.

Academic Research Review

Regarding the scientific exploration of “exercise and endometriosis,” the field of female exercise physiology has accumulated rigorous and rich evidence in recent years. Below are several representative studies selected for their value in methodological design, study populations, and strength of conclusions, which together form the foundation of our current understanding:

1. Bonocher et al. (2014). Reproductive Biology and Endocrinology reviewed the potential protective and symptom-improving mechanisms of exercise on endometriosis.

2. Hansen & Knudsen (2017). European Journal of Obstetrics & Gynecology examined the association between physical activity and the risk of endometriosis.

3. Tourny et al. (2018). Journal of Bodywork and Movement Therapies reviewed the role of exercise in the management of chronic pelvic pain.

4. Ricci et al. (2016). Human Reproduction analyzed epidemiological evidence on physical activity and the risk of endometriosis.

Taken together, these studies show that the scientific picture of “exercise and endometriosis” has deepened with advances in research methods and a growing awareness of “population specificity.” Early studies often interpreted data from adolescents, women, or special populations directly through the framework of adult males, ignoring the fundamental differences brought by developmental stage, hormonal cycles, aging processes, or disease context. In contrast, recent high-quality research increasingly emphasizes “tailored research methods for specific populations”—analyzing adolescents by biological maturity rather than chronological age, incorporating menstrual cycle and energy availability as control variables in female studies, and conducting stratified assessments of resistance training and cardiovascular risk in older adults. This methodological evolution has allowed us to progress from “treating differences as noise” to “treating differences as the core of research.” It is worth noting that this field still faces several challenges: the number of studies on women and special populations remains relatively small compared to men, and sample sizes are often limited; longitudinal tracking (especially long-term development in adolescents) is costly; and ethical considerations prevent certain interventions in vulnerable populations. Therefore, when interpreting conclusions, we must both value the population-specific insights revealed by these studies and pay attention to the level of evidence and scope of applicability—a conclusion drawn from a specific age, sex, or health status group may not be generalizable to other groups. This dual caution regarding population differences and evidence quality forms the foundation of the scientific application of female exercise physiology and is the consistent stance of this article.

Core Mechanisms

Endometriosis is a common yet often underestimated gynecological disease in which endometrial tissue grows outside the uterine cavity (e.g., on the ovaries, pelvic peritoneum), causing chronic pelvic pain, dysmenorrhea, painful intercourse, and infertility, significantly impacting quality of life and sports participation. The role of exercise in its management is an emerging topic with practical implications for female athletes. The potential beneficial mechanisms of exercise involve multiple levels. At the hormonal level, endometriosis is an estrogen-dependent disease, and regular exercise may lower circulating estrogen levels and alter estrogen metabolism, theoretically helping to suppress lesions. At the inflammatory level, the disease is associated with chronic inflammation, and the anti-inflammatory effects of exercise (reducing inflammatory cytokines, increasing anti-inflammatory mediators) may reduce inflammatory burden. At the pain management level, exercise promotes the secretion of endogenous pain-relieving substances such as endorphins, improves pain thresholds and pain modulation, and has positive effects on central sensitization in chronic pain; moderate exercise also improves pelvic blood circulation and reduces congestion. At the psychological level, chronic pain is often accompanied by anxiety and depression; exercise improves mood and coping abilities, breaking the cycle of “pain-disability-worsening mood.” Epidemiologically, some studies have found that higher physical activity is associated with a lower risk of endometriosis, but the evidence remains inconsistent and causality has yet to be confirmed. A practical tension to note is: on one hand, exercise may be beneficial; on the other hand, during acute pain flare-ups or in certain situations, intense exercise or specific movements may worsen discomfort and require individualized adjustment. For female athletes with this condition, recommendations include: coordinating management with a gynecologist, flexibly adjusting training according to symptom cycles (switching to low-intensity or different exercise types during painful periods), using exercise as a tool for pain management and emotional support, and being aware of the potential interactions between this condition and menstrual and energy status. Aerobic exercises such as cycling can serve as a gentle exercise option due to controllable intensity and improved circulation, but attention should be paid to saddle pressure on the pelvis during symptomatic periods. Importantly, endometriosis should not be a reason for women to completely give up exercise—with proper management, exercise may actually be a helpful tool for improving symptoms and quality of life. This also highlights the need for female exercise science to address these female-specific health issues and provide evidence-based guidance.

To truly understand “exercise and endometriosis,” one must return to the unique physiological context of female exercise physiology: how the developing body, fluctuating hormones, aging systems, or disease effects alter exercise responses at the cellular, tissue, and systemic levels. The table below summarizes the key points of action at different physiological levels for this topic, helping you build a complete mechanistic picture:

| Physiological Level | Key Mechanisms | Implications for Training and Health |

|—|—|—|

| Endocrine/Hormonal | Population differences in sex hormones, growth and metabolic hormones | Affects adaptation direction, energy regulation, and reproductive/skeletal health |

| Bone and Muscle | Bone mass accumulation/loss, muscle fiber composition and protein synthesis | Determines bone density, strength development, and injury risk |

| Cardiovascular and Metabolic | Population-specific characteristics of cardiac remodeling, VO₂max, and substrate utilization | Affects endurance performance, recovery, and long-term health |

| Neural and Psychological | Neuromuscular control, motivation, and psychosocial needs | Determines skill development, injury prevention, and sustained participation |

Two dimensions deserve special emphasis: “developmental stage” and “individual variability.” The same intervention may produce vastly different or even opposite effects at different levels of maturity, age, sex, hormonal status, or health conditions—this is precisely where female exercise physiology is most susceptible to being misled by oversimplified recommendations. For adolescents, for example, the effects, risks, and optimal timing of a training stimulus differ before and after PHV; for women, energy availability and menstrual function are key regulators behind many physiological responses; for older adults, anabolic resistance and the rate of decline make the meaning of “stimulus intensity” different from that in younger people. “Exercise and endometriosis” deserves in-depth exploration precisely because it can specifically affect certain key aspects of female exercise physiology. The more thoroughly you understand the mechanisms, the better you can judge “for whom, at what stage, what to do, and how much,” rather than blindly applying unsuitable general rules. This ability to adjust according to population and individual context is the dividing line between those who understand female exercise physiology and those who train blindly.

Dose-Response Relationship

In female exercise physiology, “dose determines effect” is a core principle, but this dose often needs to be recalibrated according to population characteristics. Too low a stimulus fails to reach the adaptation threshold and produces no benefit; too high a load may exceed the compensatory capacity of vulnerable populations, causing injury, developmental disruption, or health damage. The table below summarizes the dose-response correspondence for “exercise and endometriosis” and serves as the most important quantitative reference when developing training and health plans for specific populations:

| Dose / Condition | Physiological State | Effects and Key Points |

|—|—|—|

| Regular exercise | Anti-inflammatory, estrogen modulation | May reduce symptoms and lesions |

| Pain management | Promotes endogenous analgesia | Improves pain threshold and modulation |

| Adjustment during symptomatic periods | Flexibly reduce intensity/change type | Avoids worsening discomfort |

| Psychological support | Improves mood | Breaks the pain-mood vicious cycle |

As can be seen from the table above, the dose-response relationship in female exercise physiology often presents a threshold-type or inverted U-shaped curve: before reaching the effective dose, benefits increase with dose; but beyond a certain critical point, not only is there no additional benefit, but risks and costs rise sharply—this is especially critical for vulnerable populations (developing adolescents, women prone to energy imbalance, and older adults with declining compensatory capacity). This means that “finding the optimal dose for that population and individual” is far more important than “pursuing more and harder at all costs.” In practical application, it is recommended to continuously monitor responses using objective indicators (such as performance, recovery, health markers, subjective feelings) and calibrate according to population characteristics and individual data. Remember: the group average reported in research is a starting point, not an endpoint; each person’s maturity, hormonal status, health background, and genetics will cause the optimal dose to shift individually. Only by calibrating with your own data and professional assessment can you safely translate group science into a personal prescription.

Differences Across Populations

The impact of “exercise and endometriosis” is not equal for everyone. Age and maturity, sex, training status, hormonal state, health conditions, and genetic background all significantly modulate individual response magnitude. Ignoring these differences and applying a single recommendation is one of the most common and dangerous mistakes in the application of female exercise physiology.

| Population Dimension | Response Characteristics | Practical Recommendations |

|—|—|—|

| Beginner vs. Advanced | Advanced individuals have mature adaptations and better tolerance but less marginal room | Beginners should progress conservatively, building a foundation before increasing load |

| Male vs. Female | Differences in hormones, body composition, bone, and metabolic characteristics | Women need individualized assessment of energy, iron, and bone health |

| Young vs. Older | Older individuals recover more slowly, have anabolic resistance, and accelerated decline | Older adults need sufficient stimulus intensity but longer recovery and screening |

| Developmental Stage | Maturity affects adaptation direction, risk, and timing | Arrange training by biological maturity rather than age |

Regarding population-specific considerations for this topic: women of reproductive age are the primary population; symptom severity varies greatly between individuals and requires individualized coordination with gynecology.

When interpreting individual differences, one must also be wary of a statistical trap: research reports mostly “group average responses,” but beneath the average often lies enormous individual variation. In the same intervention, some may be strong responders while others barely respond. This is why even if a study shows “average effectiveness,” you still need to combine professional assessment and your own response to confirm applicability. Taking common exercise populations in Taiwan as an example—whether it’s adolescents burdened with heavy schoolwork, women balancing family and training, or middle-aged and older adults pursuing healthy aging—correctly understanding the physiological characteristics of your own population group is the only way to avoid the ineffective or even harmful consequences of “copying someone else’s training plan.” After understanding population differences, you will realize: truly professional female exercise physiology advice is always an individualized prescription that “varies by person and stage,” never a one-size-fits-all slogan.

Practical Training Applications

Theory must ultimately translate into practical training and health operations. Below is a practical framework for translating “exercise and endometriosis” into concrete applications:

• Population Matching: All training and health recommendations must first ask, “Is this suitable for this population?”—adolescents prioritize development and protection, women prioritize energy and bone health, older adults prioritize safety and functional maintenance; the starting points are all different.

• Progression and Monitoring: Progress gradually from an appropriate starting point, continuously monitor responses with objective indicators (performance, recovery, health markers) and subjective feelings, and dynamically adjust according to individual conditions.

• Health Over Performance: For vulnerable populations, long-term health (development, bone, endocrine, cardiovascular) always takes precedence over short-term performance; never sacrifice health for temporary numbers.

• Holistic Context: Training is only one piece of the puzzle; sleep, nutrition (especially energy availability), recovery, psychological and social support are equally critical—no single intervention can compensate for overall imbalance.

• Professional Collaboration: When facing growing adolescents, female-specific health issues, or older and chronically ill populations, seeking timely collaborative assessment from coaches, medical professionals, nutritionists, and psychologists is a guarantee of safety and effectiveness.

Using practical planning as an example: when developing a plan, you should first clarify the population characteristics and health context of the individual, then set reasonable goals, doses, and monitoring indicators accordingly. The most common mistake many people make is directly applying practices seen on social media or in adult elites to adolescents, women, or older adults, ignoring the underlying physiological differences—this is precisely what female exercise physiology seeks to avoid. Daily training and life are the best laboratories for observing population and individual responses and building personalized data.

It is recommended to integrate training logs with health monitoring, recording key indicators (such as growth and injuries in adolescents, menstrual and iron status in women, strength and recovery in older adults) along with training content and physical responses. After weeks to months of accumulation, the value of this personalized database will far exceed any general guide. Additionally, don’t overlook the often-underestimated aspect of “recovery and long-term development”—for vulnerable populations, excessively pursuing short-term progress at the expense of recovery and health often leads to injury, burnout, or health problems, actually interrupting the engine of long-term progress. Treat population matching and health priority as core training principles, and you will see clear differences in both your results and safety.

Local Application in Taiwan

Taiwan’s unique climate, terrain, social structure, and sports culture add a distinctive local flavor to the application of “exercise and endometriosis.” Climatically, the hot and humid summers and cold and damp winters pose additional challenges for different populations (especially adolescents and older adults with different thermoregulatory capacities); topographically, the extreme elevation change from sea level to Wuling at 3,275 meters provides a rich training environment; socially, Taiwan is entering an aging society, faces heavy academic pressure, and has rising gender equality awareness—all of which profoundly affect the exercise circumstances of various populations.

Taking local contexts as examples: adolescent athletes often face the dual pressure of academics and training, lacking systematic recovery and long-term development planning; female sports enthusiasts face insufficient attention to energy availability, iron, bone health, and female-specific health issues; older adults need friendly, safe exercise environments and communities that accommodate different abilities. Making good use of Taiwan’s dense convenience store supply points, diverse cycling and running routes, and growing sports communities, while designing appropriate activities for different populations (such as diverse development for adolescents, female-friendly equipment and environments, and group rides for older adults), is the way to truly implement the science of female exercise physiology for every sports enthusiast in Taiwan, promoting health and sports participation for all.

Debunking Common Myths

Myth: “If endometriosis hurts, you should rest completely and not exercise.” Regular exercise may improve symptoms through anti-inflammatory effects, hormonal regulation, and pain management; with proper management, it can actually be beneficial. The key is to adjust flexibly according to symptoms, not to give up exercise entirely.

These myths are widespread often because they “sound reasonable,” are easily passed by word of mouth, or stem from inappropriately applying adult male concepts to other populations. However, the value of science lies in testing intuition with rigorous evidence: many seemingly obvious ideas do not hold up under rigorous research on specific populations. The field of female exercise physiology is especially rife with outdated stereotypes and oversimplified claims that compress complex population differences, developmental stages, and individual variation into a single slogan. The next time you hear a definitive exercise recommendation for adolescents, women, or special populations, it’s worth asking: “What is the level of evidence for this claim? Is it based on research on this population? Or is it directly extrapolated from conclusions on other groups?” Cultivating this evidence-based, population-specific critical thinking is more valuable than memorizing any single conclusion, and it is a key step toward making female exercise physiology more scientific and preventing harm.

Conclusion

“Exercise and endometriosis” is a topic in female exercise physiology with both theoretical depth and practical value. As can be seen from the international journal evidence reviewed in this article, adolescents, women, and special populations have unique characteristics and needs in exercise physiology—they are by no means “scaled-down” or “special-case” versions of adult males. Understanding and respecting these differences is precisely the starting point for scientific, individualized training. The key lies in mastering mechanisms, calibrating doses, adjusting according to population and individual, and always prioritizing long-term health over short-term performance. For sports enthusiasts in Taiwan, while mastering scientific principles, it is equally important to integrate local climate, environment, and social context, transforming general rules into prescriptions suitable for one’s own population and individual. May every adolescent, woman, and older adult who sweats through exercise at various stages of life safely, healthily, and sustainably enjoy the joy and benefits of sport through the wisdom of female exercise physiology. The value of exercise has never been limited by age, sex, or condition—let science become a force that benefits everyone.
