Effects of Mat Pilates on hip and knee isokinetic torque parameters in elderly women

Mat Pilates improves lower and upper body strength and flexibility in breast cancer survivors undergoing hormone therapy: a randomized controlled trial (HAPiMat study)

PURPOSE

To evaluate the effects of 24 weeks of Mat Pilates in breast cancer survivors (BCS) undergoing hormone therapy on lower and upper body muscle strength parameters and flexibility.

MATERIALS AND METHODS

Forty-three BCS (≥40 years) with confirmed breast cancer stage 0-III undergoing hormone therapy were included. Participants were randomized into Mat Pilates (three times/week, 60 min session) or control group (relaxation activities every two weeks). The difficulty and number of exercise repetitions were increased over the weeks. Assessments were performed at three times points (baseline, 12 weeks, and 24 weeks). The generalized estimating equations (GEE) model was used to compare each outcome measure during the analysis of intention to treat (ITT) and "Per protocol analysis" (PPA).

RESULTS

The Pilates group presented significantly increased (p < 0.05) isometric flexor-extensor PT, and concentric and eccentric flexor PT and mechanical work (MW) after the intervention. Most of the upper body strength parameters, time to achieve maximal force (TF_max), maximal force (F_max), and rapid force index (RFI) and right-left upper and lower body flexibility (p < 0.05) also improved.

CONCLUSIONS

From our findings, we conclude that 24 and 12-weeks of Mat Pilates induced strength and flexibility gains for lower and upper body, respectively.Implications for rehabilitationMat Pilates can be adapted to the fitness level of breast cancer survivors, with a great variety of exercises that can be performed using a mat only or a few pieces of equipment.Patients can practice at home to gain different health benefits (i.e., increasing strength, flexibility, and functional capacity level), which could positively impact on quality of life.Mat Pilates performed three times per week with systematized increments in exercise level, load, and volume throughout the intervention was effective to improve hip extensor-flexor muscles peak torque and mechanical work at different muscle contractions, as well as upper and lower body flexibility.Mat Pilates was also able to improve right-left shoulder abductor and trunk extensor muscles strength parameters after 12 weeks of intervention, as well as both surgery and non-surgery sides of the upper body.

Effects of mat Pilates on older adult women with knee osteoarthritis: A randomized controlled trial

INTRODUCTION

Osteoarthritis is the most common joint disorder in the world and its incidence is rising, and one of the most frequent causes of pain, loss of function and disability in adults.

AIM

The aim of this study was to evaluate the effects of Mat Pilates on health status, pain, stiffness, and functionality of older adult women with knee osteoarthritis (KOA).

METHODS

A randomized-controlled trial to preliminarily test an intervention protocol of Mat Pilates in older women with KOA on health status, pain, stiffness, and functionality. This study included 41 volunteers with age over 40 years, which mean was 52.1 ± 8.9 years, and were allocated into Mat Pilates and control groups. The protocol was developed to be performed in 60 min, twice a week; the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and the Medical Outcomes Study 36 (SF-36) were used to assess pain, to evaluate functionality and stiffness.

RESULTS

The Mat Pilates group significantly improved the functional capacity assessed by SF-36 (33.12 ± 22.03 to 69.37 ± 22.43, p < 0.05), and by WOMAC (29.75 ± 6.92 to 9.75 ± 9.35, p < 0.05). The pain domain also improved in Mat Pilates group assessed by SF-36 (39.50 ± 12.89 to 71.75 ± 18.66, p < 0.05) and by WOMAC (8.00 ± 2.56 to 2.75 ± 3.01, p < 0.05). The total score of WOMAC (41.75 ± 10.39 to 14.25 ± 13.88, p < 0.05), and the general health status assessed by SF-36 (59.44 ± 18.07 to 82.75 ± 12.03, p < 0.05) only improved for Mat Pilates group. No differences were observed in outcomes for the control group in both questionnaires.

CONCLUSION

Our results show that Mat Pilates protocol can improve the health status, pain, and functionality of older women with KOA.

Benefits of Pilates in the Elderly Population: A Systematic Review and Meta-Analysis

The aim of this systematic review is to collect and summarize the benefits of Pilates in the elderly population (>60 years old), within the current scientific production, assessing its contribution to Healthy Ageing (HA). We used PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analysis) to select, collect, and analyse this thematic. The methodological procedures were registered in the PROSPERO database. The main results of the studies analysed (n = 30) point to significant differences between the intervention and the control groups in dynamic balance, strength, mobility, functional capacity, risk of falling reduction, and mental and psychological health. Thus, the results showed that Pilates may be beneficial for the health of the elderly. The meta-analysis found statistical differences between means on the dynamic balance (mean difference (MD) = −0.0, 95% CI [−0.71, −0.50]; I2: 0%) and the aerobic capacity and aerobic resistance [(MD) = 38.29, 95% CI [6.82, 69.77]; I2: 0%). Thus, it is concluded that the efficacy of Pilates has been shown in various areas of HA and has proven to be affordable and safe for the majority of people, using just a mat on the floor. Future studies should focus on the analysis of the relationship between the cost and the benefit of a Pilates intervention in the elderly population, to better understand how health costs can be minimized and to contribute to a multidisciplinary and generalized HA. Pilates has practical application for the clinicians, therapists, and health professionals that work with the elderly population.

Effects of Pilates Training on Physiological and Psychological Health Parameters in Healthy Older Adults and in Older Adults With Clinical Conditions Over 55 Years: A Meta-Analytical Review

This meta-analytical review aimed at comparing the impact of Pilates interventions (PIs) on physiological and psychological health parameters in healthy older adults and older adults with a clinical condition aged 55 years and older. The literature search was conducted in three databases (PubMed, Web of Science, SPORTDiscus). Randomized controlled trials that aimed at improving physiological and psychological health parameters in adults aged 55 years and older using Pilates as an intervention were screened for eligibility. The included data was extracted and assigned based on participants' health condition (clinical vs. non-clinical), as well as the respective control condition used in the study [inactive (IC) vs. active control group (AC)]. Statistical analyses were computed using a random-effects inverse-variance model. Fifty-one studies with a total of 2,485 participants (mean age: 66.5 ± 4.9 years) were included. Moderate effects (SMD: 0.55; 0.68) were found for physiological health parameters (muscle strength, balance, endurance, flexibility, gait, and physical functioning) in both experimental (clinical and non-clinical) conditions when compared to ICs (p < 0.003; p = 0.0001), and small to moderate effects (SMD: 0.27; 0.50) when compared to ACs (p = 0.04; p = 0.01). Moderate to large effects (SMD: 0.62; 0.83) were documented for psychological health parameters (quality of life, depression, sleep quality, fear of falling, pain, and health perception) in both conditions when compared to ICs (p < 0.001, p < 0.001). PIs induce small to large effects in physiological and psychological health parameters in older adults, regardless of their health condition. The substantial heterogeneity within the included studies complicated standardized comparison of the training modalities between the two target groups. Nonetheless, Pilates seems to be a safe, adaptable, and promising exercise approach for a heterogenous population of older adults.

The impact of an 8-week Pilates-based physical training program on functional mobility: data from a septuagenarian group

Study aim: This study aimed to evaluate the effects of a Pilates-based training program on functional mobility and strength in community-dwelling adults over 70 years old.

Material and methods: Twenty community-dwelling elderly subjects were recruited and randomly assigned to control (C = 10) or Pilates training (PT = 10) groups for 8 weeks (2 times/week). Anthropometric, strength, cardiorespiratory fitness, functional mobility, and static and dynamic balance parameters were assessed before and after the intervention.

Results: The PT group had higher values of lower limb strength (p = 0.013 d = 0.56) and 6-minute walking test distance (p = 0.04; d = 0.45) than the C group. The PT group also had differences in one leg stance duration and decrease in the Timed Up and Go test. We also observed a positive correlation between muscle strength and cardiorespiratory fitness (p < 0.01, r = 0.62), cardiorespiratory fitness and one leg stance, eyes closed, right and left leg (p = 0.04, r = 0.45; p = 0.05, r = 0.45, respectively).

Conclusions: Eight weeks of Pilates-based physical training induced improvements in skeletal muscle strength and functional mobility of community-dwelling septuagenarians.

Acute effects of mat Pilates session on heart rate and rating of perceived exertion

AIMS

The aim of this study was to analyze the acute effects of Heart Rate (HR) and Rating of Perceived Exertion (RPE) for 21 of 34 original Mat Pilates (MP) exercises, to estimate maximum oxygen consumption (VO_2max), and energy expenditure (EE) of a MP session.

METHODS

Ten participants volunteered (26.30 ± 3.98 yrs) to measure the intensity of each exercise; HR and RPE were monitored immediately after the end of each exercise. VO_2maxwas estimated using the Astrand-Ryhming step submaximal test, and EE by a linear regression equation. HR and RPE mean values and standard deviations were calculated for each exercise.

RESULTS

The maximum value for each participant normalized the EE and VO_2max values, which were ranked from highest to lowest. The percentage of the mean values of HR_max and RPE_max in each exercise showed significant, strong and positive correlation (p = 0.82; p = 0.001). In 10 exercises, HR was 60% higher than HR_max. The mean values of EE and VO_2max were 213.71 ± (76.41) Kcal and 34.69 ml (Kg^.min)^-1 (±3.5), respectively, for the entire MP session. Half of the exercises achieved moderate intensity in HR with low estimated VO_2max during the whole MP session. However, if the MP session of this study was practiced five times per week, it would meet the weekly American College of Sports Medicine (ACSM) EE recommendations.

CONCLUSION

The 21 MP exercises monitored in this study promote considerably acute and high increments in HR and RPE.

Pilates versus resistance training on trunk strength and balance adaptations in older women: a randomized controlled trial

Background

The neuromuscular decline impact in the functional independence of older women is determining the necessity of implementing new strategies focused on core strength training and postural stability maintenance to promote healthy aging.

Objectives

To define whether Pilates or resistance training is better at improving (a) core isometric and isokinetic muscular strength, and (b) static and dynamic balance, in older women.

Methods

This was a cluster randomized controlled trial. Physically independent older women (60–80 years) from day centers were randomly allocated to Pilates, Muscular and Control Groups (PG, MG and CG) using a block randomization method. Only the research staff performing the assessment and statistical analysis were blinded. Exercise groups trained twice a week (1 h per session) for 18 weeks in a moderate-to-vigorous intensity. Core strength (primary outcome): trunk and hip isometric and hip isokinetic muscular strength (Biodex System III Pro Isokinetic Dynamometer), alongside one leg static balance (portable force platform Kistler 9286AA) and dynamic balance (timed up and go (TUG)) were assessed.

Results

A total of 60 participants were randomized (PG, n = 20; MG, n = 20; CG, n = 20) and 49 completed the trial (PG, n = 16; MG, n = 19; CG, n = 14). Regarding hip isometric extension strength, PG was statistically better than CG (P = 0.004). There were no differences between groups regarding isokinetic strength or balance. Intra-group comparisons showed significant improvements (P < 0.05) in the dynamic balance and trunk and hip isometric extension strength for PG and MG, whereas every hip isokinetic measurement was improved in MG. Exercise programs did not produce any adverse event.

Conclusions

The Pilates training program was more effective for improving isometric hip and trunk extension strength, while the Muscular training program generated greater benefits on trunk and hip isokinetic strength. Moreover, both training programs showed moderate effects for the TUG.

Clinical Trial Registration

The trial was registered at ClinicalTrials.gov (identifier: NCT02506491).
