Background and objective:
The current study was published in the peer-reviewed journal Research Quarterly for Exercise and Sport in September 2009.
The purpose was to assess changes in body composition, flexibility and muscular endurance following 8 weeks of traditional mat Pilates training in a group of healthy recreationally active adults. Research documenting physiological changes following a Pilates protocol was (and still is) limited.
Methods (how was this research conducted):
22 physically active participants completed the full study: 9 adults, who were new to Pilates, were assigned to a Pilates mat program. 13 adults served as control group doing a self-prescribed, unsupervised cardio-vascular and strength protocol with the same frequency.
The control group demonstrated significantly greater abdominal and low back muscle endurance before the intervention.
All measures except for weight, hip and thigh circumference improved significantly for the Pilates group, but not the control group, after the intervention.
Limitations (things to keep in mind):
The strengths of the current study are found in its program frequency and length, as well as its statistical calculations.
It has, however, several limitations often encountered in exercise science research, which decrease internal and external validity. This doesn't mean that the results or conclusions are wrong, they can just be taken less seriously than the results of a study with greater validity: The number of participants was very small and mostly female, the participants had a relatively young average age due to the university setting, the groups weren't randomly assigned, the measurements weren't conducted blinded, and the control group’s exercise program was self-prescribed and unsupervised..
Implications (what this means for Pilates teachers):
In spite of its limitations, this study is a great demonstration of the positive effects of a classical Pilates Mat program for clients.
Its real importance however, lies in the fact that it is, to the author’s knowledge, the only study in MEDLINE that utilizes a classical Pilates protocol. This is indicated by the exercise selection and names, as well as the instructor’s background. She was certified at The Pilates Studio NY and trained with Elder Romana Kryzanowska.
The Pilates Method of Exercise: Effectiveness in the Treatment of Chronic Low Back Pain and Intervention Limitations
This first review does not introduce one, but several articles on low back pain, revealing limitations often encountered in Pilates research.
The goal of this article is to assess the effectiveness of the Pilates method in the treatment of chronic low back pain by reviewing scientific studies in which the Pilates Method was used as treatment. A critical look will be taken at the studies’ limitations and the types of exercises used.
The studies were required to meet scholarly standards, be peer reviewed and are randomized and controlled trials.
Study inclusion criteria
A Boolean search for randomized controlled and clinical trials using (Pilates) AND "low back pain" on PubMed (including MEDLINE) returned 24 results.
The effectiveness of Pilates in the treatment of low back pain
Regardless of the limitations of the selected studies described below, the success of Pilates-based exercise in the rehabilitation of low back pain is undeniable:
Due to the different measurements and intervention ranges, there is no statistical data analysis possible. Following a comparative result list:
General limitations in Pilates research
Pilates exercises are being used by physical therapists to support the rehabilitation programs for various musculoskeletal conditions, sports injuries, and neurological disorders, focusing especially on the spine and its stabilization. The increased use of Pilates-based exercises makes it imperative to understand, among other characteristics, its applications, its contraindications, and how to use it appropriately.
As numerous studies about Pilates and low back pain have been authored, the following limitations were observed:
Classical Pilates, contemporary Pilates and therapeutic exercise

Following similarities and differences of classical Pilates, contemporary Pilates and therapeutic exercise protocols:
Limitations: Exercise protocol definition and challenges
Most of the exercises taught to physical therapists in the United States for low back pain patients fall into general categories of spinal range of motion and strengthening exercises that may be described as core stability, dynamic stabilization, lumbo-pelvic and spinal stabilization, co-contraction type mat or ball exercises, progressive resistive exercises with weights or elastic bands, and functional activities.
Where is the boundary between such therapeutic exercise protocols and Pilates? A comparison of the 11 selected studies shows that the Pilates protocol used is not always clearly defined and may not even be Pilates.
Surprisingly, 2 studies do not provide any information about the exercises used (Cruz-Díaz et al., 2015 & da Fonseca et al., 2009). Da Fonseca et al. only provide brief information about muscle recruitment concepts, which indicate that the protocol is more closely related to therapeutic exercise than to Pilates.
Rydeard et al. (2006) provide a more detailed description about the exercises used, but the protocol is also about muscle recruitment strategies and doesn’t mention any Pilates exercises, in spite of the title of the study: “Pilates-based therapeutic exercise: effect on subjects with nonspecific chronic low back pain and functional disability”.
Wajswelner et al. (2012) promise “clinical Pilates” in the study title, but they use therapeutic exercises which are performed on the Pilates equipment. It is questionable if the use of equipment makes the exercises Pilates exercises.
Lastly, about a third of the mat exercises that Lee at al. (2014) use are yoga based, such as “seated hip stretch” and “knee over knee twist stretch”, not Pilates.
There is evidence that Pilates-based exercise in the rehabilitation of low back pain is effective. Additional peer-reviewed and randomized, controlled research is needed to produce scientifically reliable meta analyses, preferably utilizing similar measurements, intervention durations, frequencies and equipment.
For further scientific evaluation and in order to achieve reproducible exercise protocols and results, a standardization of contemporary Pilates exercises would be desirable. Classical Pilates has not been scientifically analyzed.
