Oxidative status alteration during aerobic-dominant mixed and anaerobic-dominant mixed effort in judokas.

This study aimed to depict the oxidative status variation in judokas during aerobic-dominant mixed effort (AeDME) and anaerobic-dominant mixed effort (AnDME). It is to be expected that the sporting commitment of Judo is a stimulus of oxidative stress leading to the recruitment of antioxidant responses. Blood samples were collected from 17 athletes at rest, immediately after a training session (AeDME) and after a 5-min bout (AnDME). AeDME and AnDME caused significant increases in malondialdehyde (MDA) (p < 0.01 and p < 0.001 respectively) and glutathione (GSH) (p = 0.018 and p < 0.001 respectively). Blood thiol concentrations decreased following AeDME and AnDME (p < 0.001) whilst catalase decreased significantly after AnDME (p = 0.026) only. Uric acid increased significantly after AnDME than after AeDME (p = 0.047) while, conversely, total bilirubin was higher after AnDME than after AeDME (p = 0.02). We may ultimately summarize that AeDME and AnDME caused oxidative stress, higher in AnDME, and some antioxidant response slightly higher in AnDME compared to AeDME. In sports, monitoring of oxidative stress status is recommended as part of the training regimen.

Is moderate-intensity interval training more tolerable than high-intensity interval training in adults with obesity?

Interval training (IT) has been shown to be a time-effective alternative to traditional training programmes in the management of obesity. Nevertheless, studies comparing the effects of different IT intensities on inflammation, muscle and liver damage, and perceptual responses in people with obesity are relatively scarce. This study aimed to compare the acute effects of two different IT protocols matched by the mean load and duration on biochemical and perceptual responses in sedentary adults with obesity. Twenty-two volunteers (age = 33.40 ± 10.01 years, BMI = 38.29 ± 7.09 kg/m²) were randomized to perform two conditions: moderate-intensity IT (MIIT) 5 × 3 min (70% of peak power output (PPO))/2 min (45%PPO) and high-intensity IT (HIIT) 8 × 1 min (90%PPO)/2 min (45%PPO). Blood samples were drawn before and after exercise for biochemical and haematological measurements. Rating of perceived exertion (RPE) was assessed during and after exercise. Perceptual pain was evaluated before, throughout and after exercise. C-reactive protein, white blood cells and neutrophils increased only after HIIT (p < 0.001, for all). Aspartate aminotransferase, alanine aminotransferase, creatine kinase and lactate dehydrogenase increased in both HIIT and MIIT (p < 0.001, for all), without any difference between sessions. HIIT induced a greater increase of blood lactate compared to MIIT (p < 0.05). Pain and RPE scores were higher during HIIT vs. MIIT (p < 0.001 and p < 0.01, respectively). MIIT induced fewer immune system perturbations and less muscle pain and was perceived as more tolerable compared to HIIT session. Therefore, MIIT could be used as a first step to promote body adaptations before starting a HIIT programme in sedentary people with obesity.

Impact of atorvastatin reload on the prevention of contrast-induced nephropathy in patients on chronic statin therapy: A prospective randomized trial.

BACKGROUND: This trial aimed to assess the efficacy of Atorvastatin reloading on the prevention of Contrast-induced nephropathy (CIN) in patients pre-treated with this statin and undergoing coronary catheterization. METHODS: This was a prospective randomized controlled study including patients on chronic atorvastatin therapy. We randomly assigned the population to the Atorvastatin Reloading group (AR group), by reloading patients with 80 mg of atorvastatin one day before and three days after the coronary procedure, and the Non-Reloading group (NR group), including patients who received their usual dose without a reloading dose. The primary endpoints were the incidence of cystatin (Cys)-based CIN and Creatinine (Scr)-based CIN. The secondary endpoints consisted of the changes in renal biomarkers (Δ biomarkers) defined as the difference between the follow-up level and the baseline level. RESULTS: Our population was assigned to the AR group (n = 56 patients) and NR group (n = 54 patients). The baseline characteristics of the 2 groups were similar. Serum creatinine (SCr)-based CIN occurred in 11.1% in the NR group, and in 8.9% in the AR group without any significant difference. Cys-based CIN occurred in 37% in the NR group and 26.8% in the AR group without any significant difference. The subgroup analysis showed that high dose reloading had significantly reduced the CYC-based CIN risk in patients with type 2 diabetes (43.5% vs 18.8%, RR = 0.43. CI 95% [0.18-0.99])). The comparison of "Δ Cystatin" and Δ eGFR between the AR and NR groups didn't show any significant difference. However, cystatin C had significantly increased between baseline and at 24 hours in the NR group (0.96 vs 1.05, p = 0.001), but not in the AR group (0.94 vs 1.03, p = 0.206). CONCLUSIONS: Our study did not find a benefit of systematic atorvastatin reloading in patients on chronic atorvastatin therapy in preventing CIN. However, it suggested that this strategy could reduce the risk of CyC-based CIN in diabetic type 2 patients.

Melatonin intake before intradialytic exercise reverses oxidative stress and improves antioxidant status in hemodialysis patients.

PURPOSE: The present study aimed to investigate for the first time the effects of melatonin (MEL) intake on oxidative stress and cellular damage during intradialytic exercise (IEX). METHODS: Thirteen hemodialysis (HD) patients volunteered to participate in the current randomized crossover trial. Participants performed four HD sessions in four different conditions: (Exercise (EX)-MEL), (EX-Placebo (PLA)), (Control (C)-MEL), and (C-PLA). 3 mg of MEL or PLA were taken 60 min before starting exercise, or at the equivalent time in the C conditions. Blood samples were taken before HD (T0), immediately after the end of IEX (T1), 60 min after IEX (T2), or at the corresponding times in the C conditions to measure free radicals damage, antioxidant biomarkers, as well as biomarkers of muscle and liver damage. RESULTS: Malondialdehyde and Advanced Oxidation Protein Products decreased in (C-MEL) (p < 0.05, d = 2.19; p < 0.01, d = 0.99, respectively) at T2 compared to T0. Catalase and total thiol levels increased in (C-MEL) (p < 0.01, d = 1.51; p < 0.01, d = 1.56, respectively) and in (EX-MEL) (p = 0.01, d = 1.28; p < 0.01, d = 1.52, respectively) at T1 compared to T0. Total bilirubin levels increased in (EX-MEL) and (C-MEL) at T2 compared to T0 (p < 0.001, d = 2.77; p < 0.001, d = 1.36, respectively), but only at T2 compared to T1 in (EX-MEL) (p < 0.001, d = 1.67). In all conditions, uric acid levels decreased at T1 compared to T0 and at T2 compared to T1, while biomarkers of muscle and liver damage remained unchanged. CONCLUSION: This pilot study is the first to show that MEL ingestion, alone or combined with IEX, could improve oxidant-antioxidant balance during HD.

Iron Deficiency Anemia Is Associated with Proprioceptive Deficit in Adult Women: a Cross-Sectional Case-Control Study.

Proprioception is essential to several conscious and unconscious sensations and automatic control of movement in daily life activities. Iron deficiency anemia (IDA) may alter proprioception as it could induce fatigue, and affect neural processes such as myelination, and neurotransmitters synthesis and degradation. This study aimed to explore the effect of IDA on proprioception in adult women. Thirty adult women with IDA and 30 controls participated in this study. The weight discrimination test was performed to assess proprioceptive acuity. Attentional capacity and fatigue were evaluated, too. Women with IDA had a significantly (P < 0.001) lower ability to discriminate weights compared to controls in the two difficult increments, and for the second easy weight (P < 0.01). For the heaviest weight, no significant difference was found. Attentional capacity and fatigue values were significantly (P < 0.001) higher in patients with IDA compared to controls. Moreover, moderate positive correlations between the representative proprioceptive acuity values and Hb (r = 0.68) and ferritin (r = 0.69) concentrations were found. Moderate negative correlations were found between the proprioceptive acuity values and general (r = - 0.52), physical (r = - 0.65) and mental (r = - 0.46) fatigue scores, and attentional capacity (r = - 0.52). Women with IDA had impaired proprioception compared to their healthy peers. This impairment may be related to neurological deficits due to the disruption of iron bioavailability in IDA. In addition, fatigue resulting from IDA due to the poor muscle oxygenation could also explain the proprioceptive acuity decrease in women suffering from IDA.

Effectiveness of Ramadan diurnal intermittent fasting and concurrent training in the management of obesity: is the combination worth the weight?

BACKGROUND AND AIMS: We investigated, in men with obesity, the efficacy of the combination of two strategies (Ramadan diurnal intermittent fasting 'RDIF' strategy vs RDIF plus concurrent training program 'RDIF-CT' strategy) known for their positive impact on body composition and then we explored the possible impact on metabolic and inflammatory biomarkers. METHODS AND RESULTS: Twenty obese men, age: 31.8 ± 7.05 years, BMI: 33.1 ± 4.2 kg m-2, performing regularly RDIF, were randomized into two groups: RDIF-CT (n = 10) and RDIF without training (RDIF-NCT) (n = 10). The RDIF-CT group participated in High intensity interval training (HIIT) program combined with resistance exercises for 4 weeks. Body composition, blood glucose, lipid profile, liver biomarkers and inflammation were assessed before and after 4-week RDIF. Both groups showed a significant decrease in weight, fat mass (FM), fat percentage (Fat%) and waist circumference (WC) and an improvement in blood glucose, lipid profile and inflammation. Fat free mass decreased significantly in RDIF-NCT (p < 0.05) while remaining unchanged in RDIF-CT. However, RDIF-CT induced greater improvements in body composition (i.e., weight, FM, Fat% and WC (p < 0.05, p < 0.01, p < 0.01 and p < 0.05; respectively)) as well as greater decrease in lipid biomarkers (i.e., TC, TG and LDL (p < 0.01 for all)), inflammation (i.e., CRP (p < 0.05)), and liver damage (i.e., ASAT, ALAT and Gamma-GT (p < 0.01, p < 0.05 and p < 0.001; respectively)) compared to RDIF-NCT group pre-post intervention. CONCLUSIONS: Our results suggest that a combination of RDIF and CT induces greater changes in body composition, lipid profile, inflammation and liver biomarkers compared to RDIF strategy alone.

Effects of intradialytic exercise in combination with melatonin supplementation on functional capacity, postural balance, and quality of life in hemodialysis patients.

INTRODUCTION: We evaluated the effect of intradialytic concurrent (resistance-endurance) training combined with melatonin (MEL) supplementation on functional capacity, muscle strength, postural balance, and quality of life (QoL) in hemodialysis (HD) patients. METHODS: Thirty-three HD patients were randomized into three groups: Exercise (EX)-MEL (n = 11); EX-Placebo (PLA) (n = 11) and Control (C)-PLA (n = 11). Participants included in the EX-MEL and EX-PLA groups were submitted to concurrent training for 12 weeks. RESULTS: EX-MEL and EX-PLA improved functional capacity, muscle strength, QoL, and postural balance parameters in eyes open and eyes closed conditions. Parameters of postural balance in the dual task condition were improved only in EX-MEL. EX-MEL induced better results in some domains of QoL compared with EX-PLA. CONCLUSION: Intradialytic concurrent training induced beneficial effects on physical function, muscle strength, postural balance, and QoL in HD patients. MEL supplementation combined with intradialytic exercise lead to better improvements in postural balance and QoL.

Performance, muscle damage, and inflammatory responses to repeated high-intensity exercise following a 40-min nap.

The purpose of this study was to examine the effect of a 40-min nap opportunity (N40) on performance during, markers of muscle damage and inflammation, and the perception of fatigue and recovery, in response to a 5-m shuttle run test (5msrt). Fifteen male amateur athletes performed the 5msrt under two conditions: N40 and no-nap condition (NN). Blood biomarkers were collected at rest and after the 5msrt to measure muscle damage (i.e., creatinine kinase (CK), lactate dehydrogenase (LDH), aspartate aminotransferase (ASAT), and alanine aminotransferase (ALAT)) and inflammation (i.e., C-reactive protein (CRP)). RPE was determined immediately after each repetition of the test and PRS and DOMS were determined 5 min, thereafter. Compared to NN, N40 improved the highest distance (p<0.001, Δ=+7.9%) and the total distance (p<0.001, Δ=+7.2%) attained during the 5msrt. Pre and post the 5msrt, participants presented lower muscle damage (i.e., CK, LDH, ASAT and ALAT) and inflammation (i.e., CRP) (p<0.05) values in the N40 compared to NN. Concerning RPE, DOMS, and PRS, there was a positive effect in the N40 vs. NN (p<0.01). N40 represents an effective method for improving repeated high intensity short-term maximal performance, PRS, and associated muscle damage and inflammation, and reducing RPE and DOMS.

Cold Water Immersion Improves the Recovery of Both Central and Peripheral Fatigue Following Simulated Soccer Match-Play.

The present study aimed to investigate the effect of cold water immersion (CWI) on the recovery of neuromuscular fatigue following simulated soccer match-play. In a randomized design, twelve soccer players completed a 90-min simulated soccer match followed by either CWI or thermoneutral water immersion (TWI, sham condition). Before and after match (immediately after CWI/TWI through 72 h recovery), neuromuscular and performance assessments were performed. Maximal voluntary contraction (MVC) and twitch responses, delivered through electrical femoral nerve stimulation, were used to assess peripheral fatigue (quadriceps resting twitch force, Qtw,pot) and central fatigue (voluntary activation, VA). Performance was assessed via squat jump (SJ), countermovement jump (CMJ), and 20 m sprint tests. Biomarkers of muscle damages (creatine kinase, CK; Lactate dehydrogenase, LDH) were also collected. Smaller reductions in CWI than TWI were found in MVC (-9.9 ± 3%vs-23.7 ± 14.7%), VA (-3.7 ± 4.9%vs-15.4 ± 5.6%) and Qtw,pot (-15.7 ± 5.9% vs. -24.8 ± 9.5%) following post-match intervention (p < 0.05). On the other hand, smaller reductions in CWI than TWI were found only in Qtw,pot (-0.2 ± 7.7% vs. -8.8 ± 9.6%) at 72 h post-match. Afterwards, these parameters remained lower compared to baseline up to 48-72 h in TWI while they all recovered within 24 h in CWI. The 20 m sprint performance was less impaired in CWI than TWI (+11.1 ± 3.2% vs. +18 ± 3.6%, p < 0.05) while SJ and CMJ were not affected by the recovery strategy. Plasma LDH, yet no CK, were less increased during recovery in CWI compared to TWI. This study showed that CWI reduced both central and peripheral components of fatigue, which in turn led to earlier full recovery of the neuromuscular function and performance indices. Therefore, CWI might be an interesting recovery strategy for soccer players.

The Use of Digital Technology to Assess Cognitive Function in Tunisian Adults.

BACKGROUND: There has been increasing evidence and support for the use of digital technology in the cognitive health field. Despite the growing use of innovative digital technology to assess cognitive function, such technology remains scarce in Arabic countries, particularly in Tunisia. OBJECTIVE: To investigate the effectiveness of a digitally delivered cognitive assessment battery in differentiating varying degrees of cognitive function in older Tunisian adults. METHODS: One hundred fifty-five Tunisian older adults (age: 62.24±7.52 years) were assigned to one of four groups: healthy controls (HC), at-risk (AR), mild cognitive impairment (MCI), and Alzheimer's disease (AD). Participants completed a translated version of the Neurotrack digital cognitive battery. RESULTS: The AD group performed significantly lower on the associative learning (p = 0.01) and associative memory assessments (p = 0.002), than the HC and AR groups. The AD group also performed worse on the inhibition measure (p = 0.008) than the HC, AR, and MCI groups. For recognition memory, the was a significant difference between all four groups (p < 0.0005), with AD having the lowest scores followed by the MCI, AR, and HC groups, respectively. There were no significant differences observed on attention, executive function and processing speed performance between the four groups (p > 0.05). CONCLUSION: The use of digital technology appears to be a viable solution to current cognitive assessment challenges for assessing cognitive function in a Tunisian population. These findings provide further support for the use of digital technology in cognitive assessment, particularly in understudied populations.

Beneficial effects of Salvia officinalis essential oil on vanadium-induced testicular injury, DNA damage and histological alterations in Wistar rats.

Vanadium has been shown to catalyze the generation of reactive oxygen species. Since free radical production and lipid peroxidation are potentially important mediators in testicular physiology and pathophysiology, the present study was conducted to elucidate vanadium-induced oxidative damage in rat testis and the ameliorative role of Salvia officinalis essential oil (SEO) against the adverse effects of this heavy metal. Adult male Wistar rats were treated daily during 10 days either with ammonium metavanadate (5 mg/kg bw, intraperitoneally), SEO (15 mg/kg bw, orally) or their combination. A group of rats receiving daily a saline solution served as a negative control. Vanadium treatment induced a significant decrease in body and reproductive organ weights, serum testosterone level and sperm number and motility. An increase in lipid peroxidation and protein oxidation as well as a marked inhibition in the activities of antioxidant enzymes in the testes and seminal vesicles indicated the occurrence of oxidative stress after vanadium toxicity. Histopathological changes in testis and seminal vesicles were also observed following vanadium administration. However, co-administration of SEO to vanadium-treated rats resulted in an appreciable improvement of these parameters, emphasizing the therapeutic effects of SEO. It can be suggested that SEO mitigates vanadium-induced reproductive damage due to its antioxidant capacity. Thus, we can hypothesize that SEO supplementation could protect against vanadium poisoning.

ß-cyclodextrin microencapsulation enhanced antioxidant and antihyperlipidemic properties of Tunisian Periploca angustifolia roots condensed tannins in rats.

This study aimed to investigate the microencapsulation of novel condensed tannins isolated from Periploca angustifolia roots, using ß-cyclodextrin macrocyclic oligosaccharides, in order to enhance their antioxidant and antihyperlipidemic potentials. Scanning electron microscopy and Fourier transform infrared spectroscopy results revealed that tannin fraction was successfully included into ß-cyclodextrin cavities proved with an encapsulation efficacy of 70%. Our in vitro findings highlighted that both pure and encapsulated tannins have efficient inhibition capacities of pancreatic lipase activity. However, the inclusion complex has the greatest, in vivo, antioxidant, and antihyperlipidemic effects. In fact, results showed that complexed tannins had markedly restored serum lipid biomarkers, lipid peroxidation, protein carbonyl oxidation, and antioxidant enzyme defense. These findings were additionally confirmed by aortic and myocardial muscle sections of histological examination. Consequently, ß-cyclodextrin microencapsulation may be considered as an effective and promising technique for tannin delivery with improved antioxidant and antihyperlipidemic activities.

Melatonin reduces muscle damage, inflammation and oxidative stress induced by exhaustive exercise in people with overweight/obesity.

BACKGROUND: Intense physical exercise leads to inflammation, oxidative stress and muscle damage, and these responses are of greater magnitude in people with obesity. Melatonin (MLT) is considered an endogenous antioxidant which may have beneficial effects against inflammation, oxidative stress and promote tissue repair after exercise. The aim of this study was to examine the effect of MLT on inflammatory parameters, oxidative stress and muscle damage in people with overweight/obesity after a high-intensity interval exercise (HIIE). METHODS: A total of 23 subjects with obesity (9 men and 14 women) age: 33.26 ± 9.81 years, BMI: 37.75 ± 8.87 kg.m-2 were randomized to participate in two experimental sessions: HIIE + Placebo and HIIE + MLT (3 mg). The HIIE protocol corresponds to 8 intervals of 1 min (90% of the maximal aerobic power (MAP)) alternating with 2 min recovery (45% of the MAP). Blood samples were drawn before and 5 min after each exercise session. RESULTS: MLT ingestion attenuated the increase of inflammation (C-reactive protein, white blood cells (P < 0.001, ηp2 = 0.45; for both) and Neutrophils (P < 0.01, ηp2 = 0.36)) and hepatic and muscle damage (Aspartate aminotransferase (P < 0.01, ηp2 = 0.25), Alanine aminotransferase (P < 0.01, ηp2 = 0.27) and Creatine kinase (P = 0.02, ηp2 = 0.23). MLT also attenuated the exercise induced lipid and protein peroxidation (i.e., Malondialdehyde (P = 0.03, ηp2 = 0.19) and AOPP (P < 0.001, ηp2 = 0.55)). Concerning the antioxidant status, MLT intake increased Thiol (P < 0.01, ηp2 = 0.26) and Catalase (P < 0.01, ηp2 = 0.32) and decreased Uric acid (P = 0.02, ηp2 = 0.2) and Total bilirubin (P < 0.01, ηp2 = 0.33). CONCLUSIONS: MLT intake before HIIE reduced muscle damage by modulating oxidative stress and preventing overexpression of the pro-inflammatory mediators in people with obesity.

Effect of Artichoke (cynara scolymus) on cardiac markers, lipid profile and antioxidants levels in tissue of HFD-induced obesity.

Obesity plays a pivotal role in the insulin resistance disease, which is related to hypertension, hyperlipidemia, type 2 diabetes mellitus, and an increased risk of cardiovascular disease. The purpose of the present study was done to evaluate the effect of artichoke leaves extract (ALE) in the high-fat diet (HFD)-induced cellular obesity and cardiac damage in Wistar rats. Body and organ weights, serum lipid profile, cardiac markers, and antioxidants enzymes were measured. Oral administration of ALE at two doses 200 and 400 mg/kg for a period of 60 days showed a significant decrease in body and organ weights, serum total cholesterol, triglycerides, LDH, ALT accompanied by decreasing in oxidative stress biomarker (MDA, and AOPP) and increasing antioxidant enzymes (SOD, CAT, and GPx) levels as compared to HFD groups. The histological findings showed a cardioprotective effect of ALE. These findings suggest that ALE exert anti-oxidant cardiac effects in HFD- induced obese rats.

Preventive effect of Artichoke (Cynara scolymus L.) in kidney dysfunction against high fat-diet induced obesity in rats.

A high-fat diet (HFD) promotes oxidative stress, which contributes to the development of kidney dysfunction. We examined the protective effects of an ethanol extract of artichoke leaves (EEA) compared to Atorvastatin (ATOR) in the kidney of Wistar rats fed a high-fat diet. The experimental animals were divided into five groups: control (Cont), HFD, HFD treated with EEA (200 mg/kg), HFD treated with EEA (400 mg/kg), and HFD treated with ATOR. Organ weights, lipid profile, renal markers, and antioxidants enzymes were measured. Oral administration of EEA (200 and 400 mg/kg) for 60 days showed a significant decrease in organ weights and kidney markers levels accompanied by decreasing in oxidative stress biomarkers as compared to HFD groups. The histological findings showed a renoprotective effect of artichoke extract. These findings suggest that EEA exerts anti-oxidant kidney effects in HFD- induced obese rats.

Diagnostic value of miR-199a and miR-21 in the plasma of infertile women with dysregulated AMH levels.

This work aimed to explore the expression pattern of circulating miR-199a-3p, miR-21-5p and miR-let7i-3p in infertile women with dysregulated AMH levels. Quantitative real-time PCR was used to measure miR-199a-3p, miR-21-5p, and miR-let7i-3p expression levels in 60 plasma samples of infertile women with low or high AMH levels. Bioinformatic analyses for microRNAs predicting target genes and molecular pathways were performed according to gene ontology (GO) analysis and KEGG pathways. Only miR-199a-3p and miR-21-5p were significantly over and under-expressed, respectively, in the plasma samples of all infertile women with low or high AMH levels versus controls (p-value = 0.01). Furthermore, the diagnostic value miR-199a-3p yielded a receiver operating characteristic (ROC) curve with area under the curve (AUC) of 0.82 with a 95% CI [0.72-0.92] and an AUC of 0.81, for miR-21-5p, 95% CI [0.69-0.92]. The combined ROC curve of miR-21 and miR-199a provided an optimal combination with AUC = 0.98, 95% CI [0.96-1], and, a cut-off point (0.42) which provided 98% sensitivity and 87% specificity. In conclusion, circulating miR-199a-3p and miR-21-5p vary significantly whenever AMH levels of infertile women are disturbed and could potentially serve as non-invasive biomarkers in distinguishing infertile from fertile women.

Iron deficiency anemia induces postural control disorders in young women.

BACKGROUND: Due to menstruation and restrictive dietary practices, women are at a particular risk of iron deficiency anemia (IDA). This hematologic manifestation could impair postural control as it induces fatigue, muscle weakness, cognitive and neurological functions alteration. AIM: This study aimed to investigate IDA effects on postural control in young women in comparison to healthy counterparts. MATERIAL AND METHODS: Twenty-four young women with IDA and twenty-four controls participated in this study. Center of pressure (CoP) excursions, in the bipedal and semi-tandem postures on the firm and foam surfaces in the eyes opened (EO) and closed (EC), were recorded, and Romberg index was calculated to evaluate postural control. Besides physical performance, attentional capacity, fatigue, and heart and respiratory rates were assessed. RESULTS: Young women with IDA had significantly higher CoP velocity (CoPv) values in the bipedal posture in both vision and surface conditions (EO [firm: P < 0.001 and foam: P < 0.01]; EC: P < 0.001), as well as in the semi-tandem posture (EO [firm: P < 0.01 and foam: P < 0.001]; EC: P < 0.001) compared to controls indicating that they had worse postural control than their peers. In addition, values of the respiratory rate (P < 0.001), attentional capacity (P < 0.001), physical performance (P < 0.001), fatigue (P < 0.001), and Romberg index on the foam surface in both postures (P < 0.05) were significantly higher in young women with IDA compared to controls. CONCLUSIONS: Physical performance, fatigue, tachypnea and attentional capacity resulting from IDA may explain postural control disorder in young women.
