How training, adequate fuelling, nutrition and recovery work together to support healthy bones and sustainable performance.

Bone health is often framed as a concern for later life. For athletes, however, the groundwork begins much earlier. Adolescence, early adulthood and the premenopausal years are important periods for building and maintaining the skeleton while training places repeated demands on bone, muscle and connective tissue.

Appropriate loading can support bone health, but exercise is only one part of the picture. Adequate energy, calcium, vitamin D, protein, sleep and recovery help create the conditions in which the body can maintain normal physiology and adapt to training.

This article is general education, not an individual training, nutrition or medical plan. Athletes with menstrual changes, recurrent injuries, suspected under-fuelling or bone pain should seek qualified care early.

Key Takeaways

·       Bone health matters throughout an athlete's career, not only after menopause.

·       Bone is living tissue that responds to the type, magnitude, rate and repetition of mechanical loading.

·       Low energy availability can affect menstrual function, bone health, recovery and performance, even when it is unintentional.

·       Resistance training and appropriate weight-bearing or impact activity can provide complementary bone-loading stimuli.

·       Protein supports the collagen-rich matrix of bone, but calcium, vitamin D, adequate energy and a varied diet also matter.

·       Persistent menstrual changes, recurrent bone stress injuries or declining performance deserve professional assessment.

·       Collagen research in female athletes is emerging; short-term biomarker findings do not yet prove improved bone density or fewer injuries.

Bone Health Starts Earlier Than Many Women Realise

Peak bone mass is the greatest amount of bone accumulated during growth. Much of it is built during childhood and adolescence, with further consolidation into early adulthood. Genetics strongly influence the result, while physical activity, nutrition, hormones and health also contribute.

That makes the early years an opportunity, not a deadline. Bone continues to remodel throughout life, and healthy habits remain worthwhile at every age. Read more in Peak Bone Mass Explained: Why Your 20s Matter More Than You Think.

Your Skeleton Is Training Too

Running, jumping, lifting and changing direction create forces through the skeleton. Muscle contractions also pull on bone through tendons. Osteocytes help sense aspects of this mechanical environment and participate in cellular signalling that influences remodelling.

Not every movement produces the same response. Bone adaptation is site-specific and depends on factors such as loading direction, rate, magnitude, novelty and training history. A repetitive activity can be excellent for fitness while providing a relatively narrow skeletal stimulus.

Why Female Athletes Have Particular Considerations

Female athletes are not one uniform group. Age, puberty, menstrual status, hormonal contraception, pregnancy, postpartum recovery, menopause, sport, training history and medical conditions can all shape individual needs. Hormones interact with energy availability and other factors involved in normal bone turnover.

A menstrual cycle can be a useful health signal for many athletes. Missing or persistently irregular periods should not automatically be dismissed as a normal consequence of hard training. Hormonal contraception can also mask the natural cycle, so concerns need individual assessment rather than self-diagnosis.

Low Energy Availability and RED-S

Low energy availability occurs when dietary energy remaining after exercise is insufficient to support the body's other needs. It can result from intentional restriction, high training demands, practical barriers to eating or simply underestimating requirements.

When the mismatch persists, it may contribute to Relative Energy Deficiency in Sport, or RED-S, a syndrome involving impaired physiological function. Potential effects include menstrual disturbance, poorer bone health, reduced recovery, recurrent illness and impaired performance. It can affect elite and recreational athletes and is not defined by body size or appearance.

Possible warning signs include menstrual changes, repeated bone stress injuries, persistent fatigue, declining performance, frequent illness, mood changes, difficulty recovering and restrictive eating patterns. These signs have many possible causes, so assessment should involve a GP or sports physician and, where appropriate, an accredited sports dietitian and other qualified practitioners.

Training That Supports Bone

Resistance Training

Progressive resistance exercise loads bones through muscular force and can support strength, balance and performance. Squats, hinges, presses, rows, lunges and loaded carries are examples, but program design should match experience, technique, injury history and sport demands.

Weight-Bearing and Impact Activity

Running, court sports, jumping and landing can provide weight-bearing or impact stimuli. More impact is not automatically better. Athletes with pain, low bone density, previous stress fracture, pregnancy or postpartum considerations, or other medical issues may need modified loading and professional guidance.

Variation, Progression and Recovery

Different movements load different skeletal sites. A varied program may combine resistance, weight-bearing movement, balance, coordination and sport-specific work. Progress gradually; abrupt increases in volume, intensity or impact can exceed the body's capacity to recover.

Current Australian adult guidance includes muscle-strengthening activity on two or more days each week, regular moderate-to-vigorous and light activity, functional activity and adequate sleep. Athletes often train beyond general guidelines, so their fuelling and recovery needs must reflect the actual workload.

Fuel the Training You Are Doing

Exercise provides a stimulus, while food supplies energy and nutrients. For active women, the priority is an overall eating pattern that supports health and training rather than a single 'bone food' or supplement.

Adequate Energy and Carbohydrate

Eating enough overall is fundamental. Carbohydrate supports training and replenishment, while regular meals and snacks can make high requirements easier to meet. A sports dietitian can help when appetite, gastrointestinal symptoms, dietary restrictions, body-composition pressure or a demanding schedule makes fuelling difficult.

Calcium and Vitamin D

Calcium is a major mineral in bone, and vitamin D supports calcium absorption and mineralisation. Australian and New Zealand Nutrient Reference Values provide age- and life-stage-specific calcium recommendations. These are population reference values, not automatic supplement doses. Food intake, sun exposure, vitamin D status, medicines and medical history should guide individual advice.

Protein and the Collagen Matrix

Protein supplies amino acids used to build and renew many tissues. Type I collagen forms most of bone's organic matrix, which is then strengthened by minerals. Protein therefore matters for bone as well as muscle, but it cannot replace adequate energy, calcium, vitamin D or appropriate training.

What the Collagen Research Actually Shows

A 2026 randomised pilot trial studied 22 endurance-trained premenopausal women who ran more than 56 kilometres per week. After four weeks, 20 grams of collagen peptides per day affected some short-term markers of bone formation, signalling and inflammation compared with an isocaloric control.

This is interesting early research, but it has important limits: the sample was small, the intervention was brief and the study measured biomarkers rather than bone mineral density, bone strength or bone stress injury rates. It does not establish that collagen supplements strengthen bones or prevent fractures. Larger, longer trials with structural and clinical outcomes are needed.

Athletes considering supplements should first address total energy intake and the broader diet, then seek qualified advice. Products should also be checked for safety, suitability and sport-specific anti-doping requirements.

Recovery Is Part of the Program

Training is the stimulus; adaptation unfolds during the hours and days that follow. Sleep, sufficient food, hydration and sensible load management support the ability to train consistently. Recovery does not mean avoiding challenge—it means balancing challenge with the resources and time required to respond.

Persistent soreness, fatigue, declining performance or repeated injuries are reasons to review the plan. Learn more in Muscle Recovery Explained.

A Practical Framework for Active Women

1.         Include appropriately programmed resistance training and weight-bearing movement.

2.         Increase load, running volume and impact gradually rather than through sudden spikes.

3.         Eat regular meals and snacks that match training demands; do not rely on hunger alone during heavy blocks.

4.         Include suitable protein foods across the day, calcium-rich foods and a wide variety of plant foods.

5.         Use carbohydrate around training according to workload, preferences and individual goals.

6.         Protect sleep and schedule easier sessions or rest when fatigue accumulates.

7.         Track health signals such as menstrual changes, recurrent injuries, illness, mood, recovery and performance.

8.         Seek early professional support rather than trying to train through bone pain or prolonged under-fuelling.

Where Bone Broth Fits

Bone broth is not a treatment for low bone density, low energy availability, RED-S or a bone stress injury. It does not replace adequate fuelling, calcium-rich foods, vitamin D, resistance training or medical care. Protein content varies substantially, so check the nutrition information rather than assuming every broth is protein-rich.

When a product provides meaningful protein according to its label, bone broth can be one convenient food within a varied diet—for example as a warm drink or a base for meals containing vegetables, grains, legumes and other protein sources. Read Functional Proteins Explained or the Bone Broth Benefits Complete Guide.

Broth & Co's publicly available clinical study investigated digestive health. It was not a study of bone density, RED-S, athletic performance or fracture prevention.

Frequently Asked Questions

Why should young female athletes think about bone health?

Adolescence and early adulthood are important for building peak bone mass, while training, fuelling, hormones and recovery continue to affect bone throughout life. Early attention supports both health and sustainable performance.

Does running strengthen bones?

Running provides weight-bearing impact, but the response varies by skeletal site, training history and dose. Runners can benefit from appropriately programmed resistance training and, where suitable, varied multidirectional loading.

Are missed periods normal for athletes?

No. Menstrual changes can have several causes and should not simply be accepted as proof of hard training. Seek medical assessment, especially when changes persist or occur with fatigue, restricted eating, weight change, pain or recurrent injury.

What is low energy availability?

It is a mismatch in which the energy remaining after exercise is insufficient to support the body's other needs. It may be intentional or unintentional and can occur in athletes of any body size.

Do collagen peptides prevent bone stress injuries?

There is not enough evidence to make that claim. A small, short-term study found changes in some biomarkers, but did not measure whether collagen prevented injuries or improved bone density.

When should an athlete seek professional help?

Seek prompt advice for focal bone pain, suspected stress fracture, missed or persistently irregular periods, recurrent injuries, ongoing fatigue, frequent illness, significant dietary restriction or declining performance. Sudden or severe symptoms require urgent care.
