A gendered view of performance
Dr Xanne Janse de Jonge is placing the little-explored field of female hormones in sport performance in the research spotlight.
The gender divide in science has oft-seen research focusing on humans in general, rather than differentiating men and women. The fundamental biological differences between men and women are under-explored, with women under-represented in a range of medical studies. It’s an area that Xanne is examining in her work on women and exercise performance.
An ongoing curiosity about how the body worked had people suggesting Xanne pursue a career in medicine – but she sought a more sporting-bent. “What got me into studying Sport Science was mainly my own competitive sport background,” Xanne explains.
“Throughout high school I was involved in rowing at a high level, competing at World Championships and other events. And that made me think ‘What’s actually happening to my body with this much training and what do we really know about this?’.”
Upon completing her ‘doctorandus’ studies in Amsterdam (Bachelor’s and Master’s), Xanne spent four years travelling between Australia and the Netherlands on various research scholarships before undertaking her PhD at Sydney Uni. Her research topic was on the menstrual cycle and exercise performance and it was during this time that her interest in focussing on women through sport science was cemented. “It’s an area that’s typically been underexplored as most of the research in sport science is conducted with male participants. But now we’re saying, ‘hang on, can we really just apply that theory to females or should we look at them separately?’”
Women in research
“When I first came to Australia I was working with a PhD student who was exploring females and aspects of ageing,” Xanne says.” As a control group, she asked Xanne to test a group of younger women.”
“We did strength testing and when I started analysing the data there was a really big variation in the results. So I started looking deeper and realised that what we really needed to ask was which stage of the cycle the women were in, and whether they were on oral contraceptives. That really got my interest up as when I was trying to explain the large variation of results I thought it’s probably because of female hormones so that’s why I started working on it.”
It’s not just the menstrual cycle that Xanne is researching, she’s also exploring the impact of oral contraceptives on hormone fluctuations, and won’t stop there. “But of course you can look through the whole life-cycle including menopause and Hormone Replacement Therapy,” says Xanne with increasing excitement and enthusiasm. “There’s already been some research in that area where they’ve shown a difference in strength between older women on HRT and those without and that’s what we’re trying to ascertain – do natural hormonal fluctuations during the menstrual cycle and synthetic hormones in the oral contraceptive pill give you that same effect?”
Coastal views of sport
UON Central Coast is a hub for exercise and sport science, with many researchers working with local sporting groups. Upon arriving at UON Xanne approached the Central Coast Mariners Football team and has been working with them for over 10 years now. “We’re monitoring whether players are ready to compete or train again after matches. We’re working with the players after matches and do some wellness and physical fitness tests to provide feedback to their coaches on whether they’re ready to train – or if they might need some rest or rehab first”.
While it was competitive rowing that first sparked Xanne’s interest in sport science, it’s Judo that’s Xanne’s current focus working with the national team and being on the Sport Science Advisory committee, helping with coaching and more. “I think it’s really important for research academics to show that they’re passionate about the field they’re working in,” says Xanne. “I love to do judo and go to the gym with the kids. The whole family is involved in judo, so we try to fit the rest of life around it.”
Xanne feels that she’s barely scratched the surface in terms of research into women, hormones and performance, “I’d love to gather a few more HDR students to really explore this topic,” she says.
A numbers game
One of the problems Xanne faces in pursuing her research is in recruiting enough women participants to study. “You need to find enough females that have regular cycles to commit to three months of training,” Xanne explains.
“In around 30 per cent of women the hormones don’t do what we expect them to – there are so many variations in the cycle. You can have your period without regular ovulating, so the hormones that women experience aren’t similar.”
In order to understand the women’s cycle, Xanne and her team take blood samples at three different times of the month to assess hormone levels and have the women do a urine test at ovulation time. “We then ask the women to advise the team when they get their period.” All this information is needed to make sure the women are tested at the right time in their cycle.
Xanne’s early work explored the hormonal cycle and its impact on muscle function (strength), but now she’s exploring how training can be adapted over the cycle. Xanne and her team are exploring if training more at certain times of the cycle will result in better and quicker training responses, such as an increase in strength. She has also explored temperature regulation; “With endurance exercise in hot conditions this definitely has an adverse effect,” Xanne says. “When you’re already hot for the two weeks after ovulation and you then start exercising in the heat, it only makes sense that you won’t perform as well.”
Xanne is one of a small team of global collaborators exploring this field. “I’ve got a PhD student coming from Spain to work with us for the last few months of her research, and we also have links in the US.”
Performance doesn’t only apply to sport performance, Xanne is also translating her work for the Defence Force and military, “We’re exploring the discussion around women in combat roles and which roles they’re suited to and how to best prepare them. It’s a new area that I’ve been invited to speak about at an International Symposium.”
It’s not just elite athletes who will benefit from this work – it will be applicable to all the female population - even if it’s just about motivation to go to the gym! “If you know that exercise is easier at certain times of the cycle, then you can plan your exercise routine around that.”

Career Summary
Biography
Xanne completed her "doctorandus" studies (Bachelor's & Master's) in Human Movement Sciences at the Vrije Universiteit Amsterdam in 1995. Her major was Exercise Physiology and as part of her studies she conducted a research project at the University of Sydney. Xanne spent the next few years travelling back and forth between Sydney and Amsterdam on research awards and fellowships. She settled permanently in Australia in 1998 and completed her PhD on the menstrual cycle and exercise performance at the University of Sydney in 2002. She then worked as an Exercise Physiologist in musculo-skeletal rehabilitation, as a sports facility coordinator and as a lecturer at the University of Western Sydney. Since 2006 Xanne has been a lecturer in Exercise & Sport Science at the University of Newcastle. Besides her research interest in exercise performance and trainability in females, Xanne has also been collaborating on applied sport science research with the Central Coast Mariners FC and the Judo Federation of Australia.
Research ExpertiseOne of the main areas of my research so far has been the effects of female hormones on exercise performance. Throughout ovulatory menstrual cycles women are exposed to continuously changing female steroid hormone profiles, while the use of oral contraceptives suppresses these fluct. The physiological changes accompanying these hormone fluctuations may affect exercise performance. As an acknowledgement of my expertise in this area I was invited to write a review on this topic for Sports Medicine. Research into the effect of the menstrual cycle on exercise has grown significantly since publication of my review. It signifies an important step in the catch up in the area of female exercise physiology. Areas of focus in my menstrual cycle research are temperature regulation, endurance performance, aerobic performance and muscle function. I am also interested in assessing if the "trainability" of females is affected by the fluctuations in female steroid hormones. My research on the influence of the menstrual cycle phase on skeletal muscle characteristics was published in the Journal of Physiology. This research addressed methodological problems identified in earlier work and provided clarification on an ambiguous topic. The research investigated muscle function during three phases of the menstrual cycle (early follicular, late follicular and mid luteal) as identified by significantly different concentrations of oestrogen and progesterone. Muscle function was measured both through voluntary muscle contractions and through the use of electrical stimulation. The results of this study suggest that the fluctuations in female reproductive hormones throughout the menstrual cycle do not affect muscle strength, fatiguability and contractile properties. My other areas of research are described below in the section "Collaboration".
Collaborations
A strong research focus is the time-motion analysis of soccer through our link with the Central Coast Mariners Football Club. GPS technology is used to record position, velocity and acceleration during matches and training. The advantage of GPS technology is that it is more accurate than previous techniques and is able to record position and velocity for every second of a match and/or training session. The Exercise & Sport Science staff and research students are tackling the challenge of processing and analysing the enormous amount of data and generating a useful summary of the player's performance. This information is useful because it allows the estimation of the physiological demands of playing soccer. It also provides useful information to coaches that can be used to design optimal training regimes. In 2010 Xanne spend 5 months at the VU University Amsterdam collaborating on research on methods of training monitoring during team sports, in particular soccer. Xanne has also established links with psychology to focus on wellness of professional soccer players. As part of the Sport Science Advisory Committee of the Judo Federation of Australia, Xanne is involved in applied sport science research in judo focusing on the national team. In 2017 Xanne was invited to present at the International Congress on Soldiers' Physical performance on the biological aspects of gender integration on military performance.

ABSTRACT: Romero-Parra, N, Rael, B, Alfaro-Magallanes, VM, Janse de Jonge, X, Cupeiro, R, and Peinado, AB; On Behalf of the IronFEMME Study Group. The effect of the oral contraceptive cycle phase on exercise-induced muscle damage after eccentric exercise in resistance-trained women. J Strength Cond Res 35(2): 353-359, 2021-To evaluate the influence of the active pill phase versus withdrawal phase of a monophasic oral contraceptive (OC) cycle on exercise-induced muscle damage and inflammation after eccentric resistance exercise. Eighteen resistance-trained female OC users (age: 25.6 ± 4.2 years, height: 162.4 ± 5.0 cm, and body mass: 58.1 ± 5.7 kg) performed an eccentric squat-based exercise during the active pill phase and withdrawal phase of their OC cycle. Muscle soreness, counter movement jump (CMJ), and blood markers of muscle damage and inflammation were evaluated before and postexercise (0, 2, 24, and 48 hours). Creatine kinase (CK) values were higher in the withdrawal (181.8 ± 89.8 U·L-1) than in the active pill phase (144.0 ± 39.7 U·L-1) (p < 0.001). The highest CK concentrations and muscle soreness values were observed 24 hours postexercise (217.9 ± 117.5 U·L-1 and 44.7 ± 19.7, respectively) compared with baseline (115.3 ± 37.4 U·L-1 and 4.4 ± 9.2, respectively; p < 0.001). In addition, a decrease in CMJ immediately postexercise (20.23 ± 4.6 cm) was observed in comparison with baseline (24.2 ± 6.1 cm), which was not yet recovered 24 hours postexercise (21.9 ± 5.9 cm; p < 0.001). No other phase or time effects were observed. An eccentric squat-based exercise session elicits muscle damage but no inflammation response in resistance-trained women. Furthermore, the highest CK concentrations observed in the withdrawal phase suggest that this phase might be more vulnerable to muscle damage and, therefore, less adequate to administer high training loads. However, the lack of differences in other muscle damage variables between OC phases does not warrant any guidance on the active pill versus withdrawal phase.

This study aimed to determine the relationship between subtypes of neuropathy and vascular reactivity on foot bone density in people with diabetes. Methods A case¿control observational design was utilised with two groups: those with diabetic peripheral large fibre neuropathy (n¿=¿23) and a control group with diabetes but without neuropathy (n¿=¿23). Bone density in 12 foot bones was determined with computed tomography scanning. Additionally, post-occlusive reactive hyperemia, presence of small fibre neuropathy and heart rate variability were determined. T-tests and hierarchical regression were used to examine the relationships among the variables. Results No difference in foot bone density was found between those with and those without large fibre neuropathy. Furthermore, no association between heart rate variability or reactive hyperemia and bone density was found. Small fibre neuropathy was associated with increased cuboid trabecular bone density (p¿=¿0.006) with its presence predictive of 14% of the variance. Conclusions This study found no clear association between presence of diabetic neuropathies and foot bone density. Furthermore, vascular reactivity appears to have no impact on bone density.

Treatment outcomes, however, are highly variable, which may be related to the method of delivery of core strengthening programmes. We investigated the effect of identical 8 week core strengthening programmes delivered as either supervised or home-based on measures of core stability. Methods Participants with poor core stability were randomised into three groups: supervised (n=26), home-based (n=26) or control (n=26). Primary outcomes were the Sahrmann test and the Star Excursion Balance Test (SEBT) for dynamic core stability and three endurance tests (side-bridge, flexor and Sorensen) for static core stability. The exercise programme was devised and supervised by an exercise physiologist. Results Analysis of covariance on the change from baseline over the 8 weeks showed that the supervised group performed significantly better on all core stability measures than both the home-based and control group. The home-based group produced significant improvements compared to the control group in all static core stability tests, but not in most of the dynamic core stability tests (Sahrmann test and two out of three directions of the SEBT). Conclusions Our results support the use of a supervised core-strengthening programme over a home-based programme to maximise improvements in core stability, especially in its dynamic aspects. Based on our findings in healthy individuals with low core stability, further research is recommended on potential therapeutic benefits of supervised core-strengthening programmes for pathologies associated with low core stability.
