Hypertrophy of Lumbopelvic Muscles in Inactive Women: A 36-Week Pilates Study.

ABSTRACT:

Background

The use of Pilates in various fields of sport sciences and rehabilitation is increasing; however, little is known about the muscle adaptations induced by this training method.

Hypothesis

A standardized Pilates training program for beginners (9 months; 2 sessions of 55 minutes per week) will increase the muscle volume and reduce potential side-to-side asymmetries of the quadratus lumborum, iliopsoas, piriformis, and gluteus muscles (gluteus maximus, medius, and minimus).

Study design

Controlled laboratory study.

Level of evidence

Level 3.

Method

A total of 12 inactive, healthy women (35.7 ± 5.4 years) without previous experience in Pilates were randomly selected to participate in a supervised Pilates program (36 weeks, twice weekly). Muscle volume (cm³) was determined using magnetic resonance imaging at the beginning and end of the intervention program. Side-to-side asymmetry was calculated as [(left - right volume) × 100/right volume].

Results

Small, nonsignificant (P > 0.05) differences in the volume of the quadratus lumborum, iliopsoas, piriformis, and gluteus muscles were observed between pre- and post-Pilates program timepoints. Before and after Pilates, side-to-side asymmetry was less than 6% and nonsignificant in all muscles analyzed.

Conclusion

Modern Pilates performed twice weekly for 9 months did not elicit substantial changes in the volume and degree of asymmetry of the selected lumbopelvic muscles in inactive women.

Clinical relevance

The benefits of Pilates in rehabilitation or training are likely elicited by neuromuscular rather than morphological adaptations. Pilates has no significant impact on muscle volume and does not alter side-to-side ratios in muscle volume (degree of asymmetry) of the lumbopelvic muscles.

Project description:The aim of this study was to compare the effect of pelvic floor muscle training with surface electromyographic (sEMG) biofeedback (BF group) and Pilates exercises (P group) on the bioelectrical activity of pelvic floor muscles in women with stress urinary incontinence. The other aim aim was to compare changes in voiding diaries and scores on quality of life questionnaire against baseline values and between the groups. Women in the BF group (n = 18) participated in pelvic floor muscle training with sEMG biofeedback; the P group (n = 13) participated in basic level Pilates workouts. Both protocols were continued for eight weeks. Voiding diary, quality of life and electromyographic characteristics of the pelvic floor muscles were assessed at the three-time points: at baseline, after eight weeks' training, and at month six post-training. The sEMG activity of the pelvic floor muscles was tested during five trials in two positions. There was no marked improvement in bioelectrical activity of the pelvic floor muscles during contraction following training with sEMG biofeedback or Pilates exercises. Following eight weeks of sEMG biofeedback training, a decrease was noted in resting bioelectrical activity of pelvic floor muscles and during relaxation after sustained contraction but only in supine-lying. No such effect was observed in the Pilates group. In the BF group, the number of incontinence episodes after end of treatment (timpepoints: 1vs. 2) and at six month follow-up (timpepoints: 1vs. 3) decreased by 68.5% and 89.3%, respectively. The respective values in the P group were 78.6%, and 86.4%. The intergroup differences did not reach the level of statistical significance. As regards the quality of life, the questionnaire demonstrated that Pilates exercises had significantly better effects compared to biofeedback training both at the end of the eight-week exercise program and (p = 0.003) and at six month follow-up (p = 0.0009). The International Consultation on Incontinence Questionnaire-Short Form (ICIQ- SF) showed comparable efficacy of Pilates exercises and training with sEMG biofeedback. Intragroup improvements in micturition frequency, incontinence (leakage) episodes, and nocturia frequency were comparable. Alleviation of urinary incontinence symptoms was comparable in both groups, whereas the improvement in the quality of life was more notable in the Pilates group. The obtained results failed to demonstrate the superiority of any of the two methods regarding the bioelectrical activity of pelvic floor muscles in patients with stress urinary incontinence.

Project description:Background: The aging society worldwide carries public and inevitable issues. Aging is accompanied by multiple diseases, and the health impacts challenge healthcare and social systems. In addition to medical treatment, exercise has been recognized as an effective strategy not only for disease prevention and alleviation, but also for multiple health benefits on health promotion. The purpose of this study was to investigate the effects of a suitable Pilates exercise intervention program on health maintenance and benefits in community-dwelling middle-aged women with a quasi-experimental design. Methods: We recruited healthy middle-aged community-dwelling women who had not regularly exercised in the previous three months. The participants were assigned to the experimental (n = 22) and control (n = 23) groups based on a quasi-experimental design. The experimental group participated in a mat-based Pilates exercise class twice a week (1 h/session) throughout the 12-week intervention, whereas there was no intervention for the control group. Body composition, basal metabolic rate, and functional physical fitness—comprising cardiovascular capacity, flexibility, muscular strength of upper limbs, muscular strength of lower limbs, core strength, agility, static balance, and dynamic balance—were assessed as primary outcomes in both groups before and after the intervention. Results: There were no significant differences in any of the dependent variables between the two groups before the exercise intervention. After the 12-week intervention, body composition, including body mass index, body fat (−1.5 to 3%), and basal metabolic rate (+10.6%), and functional fitness, including flexibility (+3.5%), core strength (+31.5%), lower-limb strength (+13.5%), agility (+7.3%), and balance (+4.2%), improved significantly in the experimental group relative to the control group (p < 0.05). Moreover, the improvement in physical fitness in lower-limb strength, agility, and balance for fall prevention also demonstrated higher clinical significance than the control. Conclusions: This 12-week mat-based Pilates exercise program significantly improved body composition, basal metabolic rate, and functional physical fitness in community-dwelling middle-aged women. The beneficial effects of Pilates exercise programs may thus promote improved health in the middle-aged female population, with practical implications for communities.

Project description:We report active treatment group differences on response and remission rates and changes in anxiety severity at weeks 24 and 36 for the Child/Adolescent Anxiety Multimodal Study (CAMS).CAMS youth (N = 488; 74% ? 12 years of age) with DSM-IV separation, generalized, or social anxiety disorder were randomized to 12 weeks of cognitive-behavioral therapy (CBT), sertraline (SRT), CBT+SRT (COMB), or medication management/pill placebo (PBO). Responders attended 6 monthly booster sessions in their assigned treatment arm; youth in COMB and SRT continued on their medication throughout this period. Efficacy of COMB, SRT, and CBT (n = 412) was assessed at 24 and 36 weeks postrandomization. Youth randomized to PBO (n = 76) were offered active CAMS treatment if nonresponsive at week 12 or over follow-up and were not included here. Independent evaluators blind to study condition assessed anxiety severity, functioning, and treatment response. Concomitant treatments were allowed but monitored over follow-up.The majority (>80%) of acute responders maintained positive response at both weeks 24 and 36. Consistent with acute outcomes, COMB maintained advantage over CBT and SRT, which did not differ, on dimensional outcomes; the 3 treatments did not differ on most categorical outcomes over follow-up. Compared to COMB and CBT, youth in SRT obtained more concomitant psychosocial treatments, whereas those in SRT and CBT obtained more concomitant combined (medication plus psychosocial) treatment.COMB maintained advantage over CBT and SRT on some measures over follow-up, whereas the 2 monotherapies remained indistinguishable. The observed convergence of COMB and monotherapy may be related to greater use of concomitant treatment during follow-up among youth receiving the monotherapies, although other explanations are possible. Although outcomes were variable, most CAMS-treated youth experienced sustained treatment benefit.

Project description:BackgroundIndividuals with celiac disease must follow a strict gluten-free diet (GFD) in order to avoid negative short- and long-term health consequences. Unfortunately, many people with celiac disease report poor quality of life (QoL) despite following a strict GFD, and up to 30% still report negative symptoms (eg, gastrointestinal upset).PurposeThe purpose of the MOVE-C (understanding the relationship between the MicrobiOme, Vitality, and Exercise in Celiac disease) pilot study is to explore the effects of a 12-week supervised progressive high-intensity interval training (HIIT) and lifestyle intervention on physiological, behavioral, and psychosocial outcomes among inactive adults with celiac disease.Methods/Design: Sixty inactive adults diagnosed with celiac disease will be randomized to HIIT+ or waitlist control (WLC). Participants in the HIIT+ will engage in a 12-week HIIT + lifestyle education program. HIIT sessions will be comprised of 2 workouts per week, working up to 14 × 30-second intervals at 90% maximal heart rate (HRmax) followed by 2 minutes recovery at 50% HRmax. The 6 biweekly lifestyle sessions will involve education on the promotion of a whole foods GFD, sleep hygiene, psychosocial coping skills (eg, self-compassion), and self-regulatory skills to master changes in behaviors. Assessments will occur at pre and post 12-week intervention and 3-month follow-up. WLC participants will be offered a 12-week HIIT program + online lifestyle education sessions after completing the final assessment. The primary outcomes are QoL and gut microbiota composition assessed with 16S rRNA sequencing. The secondary outcomes are markers of metabolic syndrome (waist circumference, fasting glucose, serum lipids, blood pressure, and body composition), gastrointestinal symptoms, sleep quality, adherence to a GFD, exercise behavior, self-regulatory efficacy, and self-compassion. It is hypothesized that participants in the HIIT+ will experience improvements in all outcomes when compared to those in the WLC. These improvements are expected to be maintained at the 3-month follow-up.DiscussionThe findings from this study will advance the knowledge regarding the effects of HIIT and lifestyle education on key outcomes for an at-risk chronic disease population. Furthermore, the findings can be used to inform future programs to improve fitness and physical and mental health outcomes for people with celiac disease.

Project description:ObjectivesPregnancy-related lumbopelvic pain (LPP) is a frequent condition known to significantly affect women in their daily life. The aetiology of pregnancy-related LPP pain is still not clearly established but the mode of conception has been suggested to contribute to LPP. Anxiety related to fertility treatments may be one of the contributing factors. The primary objectives of this study were to determine the evolution of LPP prevalence and severity, and anxiety throughout pregnancy in women who conceived spontaneously (SP) or after fertility treatments (FT). A further aim was to examine the relationship between pregnancy-related LPP severity and anxiety. The secondary objective was to determine the evolution of physical activity and their correlation with the severity of pregnancy-related LPP.DesignProspective cohort study.SettingPregnant women were recruited through physicians' referrals, posters and newspaper advertisements in the local and surrounding communities (hospital, maternity care clinic, prenatal centres, sports centres, local university) in the city of Trois-Rivières, Canada.Participants59 pregnant women (33 SP and 26 FT) were assessed during the first, second and third trimester of pregnancy.Primary and secondary outcome measuresPregnancy-related LPP prevalence and severity (primary), trait and state anxiety, and physical activity levels (secondary).ResultsThere was no relationship between the mode of conception and the outcome measures. The prevalence and severity of LPP increased over the course of pregnancy (time effect, p<0.0001) whereas trait anxiety decreased from early to mid-pregnancy (time effect, p=0.03). Activity limitations increased throughout pregnancy (time effect, p<0.0001) and physical activity levels decreased (time effect, p<0.0001). The severity of LPP was positively correlated with activity limitations (r=0.51?to 0.55) but negatively with physical activity levels (r=-0.39?to -0.41).ConclusionsMaternal health-related factors, such as LPP, anxiety and physical activity, are not different in women who conceived spontaneously or after fertility treatments. The more LPP was severe, the more the women were physically limited and inactive.

Project description:INTRODUCTION:Physical exercises have been recommended to improve the overall well-being of patients with fibromyalgia, with the main objective of repairing the effects of lack of physical conditioning and of improving the symptoms, especially pain and fatigue. Although widely recommended and widely known, few studies support the use of Pilates as an effective method in improving the symptoms of the disease, comparing it with other well-founded exercise modalities. This protocol was developed to describe the design of a randomised controlled study with a blind evaluator that evaluates the effectiveness of mat Pilates, comparing it with aquatic aerobic exercises, in improving pain in women with fibromyalgia. METHODS:Sixty women aged 18-60 years with a diagnosis of fibromyalgia, with a score of between 3 and 8 points on the Visual Analogue Scale for pain, and who sign the clear and informed consent form will be recruited according to the inclusion criteria. They will be randomised into one of the two intervention groups: (1) Pilates, to perform an exercise programme based on mat Pilates; and (2) aquatic exercise, to participate in a programme of aerobic exercises in the swimming pool. The protocol will correspond to 12 weeks of treatment, with both groups performing the exercises with supervision twice a week. The primary outcome will be pain (Visual Analogue Scale for pain). The secondary outcomes are to include impact related to the disease, functional capacity, sleep quality and overall quality of life. The evaluations will be performed at three points: at baseline and after 6 weeks and 12 weeks of treatment. ETHICS AND DISSEMINATION:This protocol has been approved by the Ethics Committee of FACISA/UFRN (number: 2.116.314). Data collection will begin after approval by the ethics committee. There will be prior contact with the women, at which time all the information about the study and the objectives will be presented, as well as resolution no 466/2012 of the National Health Council of Brazil for the year 2012, which provides guidelines and regulatory standards for research involving human beings. Participants must sign the informed consent form before the study begins. TRIAL REGISTRATION NUMBER:NCT03149198.
