Effectiveness of combined physical exercise and cognitive training in older adults with cognitive impairment: A systematic review and meta-analysis

Falls among cognitively impaired older adults are a global concern. The aim of this study was to assess the efficacy of combining physical exercise and cognitive training to improve balance among older adults. A systematic search of databases, including Embase, Medline-OVID, CINAHL-EBSCOhost, and Central-Cochrane Library, was conducted from March 9 to April 6, 2023. The search used keywords based on the PICO question, where the population was older adults with cognitive impairment. Compared to a single therapy, the intervention involved a combination of muscle strengthening and cognitive therapy, with the outcome of falls or balance. Inclusion criteria were randomized controlled trials (RCTs) in any setting. Studies with participants under 60 years old and lacking baseline clinical assessments were excluded. EndNote 20 was used as a reference manager tool, and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 flow diagram was used to map out the number of identified records. Two investigators worked independently, and the Jadad scale was used for critical appraisal. The PROSPERO registration number is CRD42023454876. A fixed-effects meta-analysis was performed using an inverse-variance method. Four articles met the inclusion criteria, three of which were included in the meta-analysis. Studies were from Europe, New Zealand, and the Philippines, with a total sample of 255 participants and mean ages of 65.9–87.5 years. The studies used combined physical and cognitive training in one group. Results showed a significant moderate effect size (effect size (ES): 2.29; standardized mean difference (SMD): 0.41; p<0.05; heterogeneity (I2): 0%) indicating no heterogeneity. In conclusion, the combined intervention displayed the potential to improve balance for cognitively impaired older adults.

Impact of Combined Exercise and High-Intensity Interval Training on 6-Minute Walk Test Dynamics in Heart Failure Patients with Preserved Ejection Fraction: Results from the ExIC-FEp Trial

(1) Background: Heart failure with preserved ejection fraction (HFpEF) is a clinical challenge, with limited success from current therapeutic strategies. This study aimed to assess the impact of combined exercise (CE) and high-intensity interval training (HIIT) on key biomechanical parameters during the 6-minute walk test (6MWT) in HFpEF patients. (2) Methods: A randomized controlled trial was conducted in 76 sedentary HFpEF patients, divided into three groups as follows: the CE, HIIT, and control groups. CE involves aerobic and strength training, whereas HIIT includes high-intensity intervals. Cadence (steps per minute), distance, maximum heart rate (HRmax), and exercise intensity were measured pre- and postintervention. (3) Results: The results revealed significant improvements in cadence in the CE group compared with the control group (p = 0.009) for intention-to-treat analysis, and in the control and HIIT groups (p = 0.002) for per-protocol analysis. CE also significantly improved HRmax and exercise intensity, suggesting an enhanced cardiovascular response. In contrast, HIIT did not significantly affect these parameters. The correlation between cadence and distance covered during the 6MWT was strong in the overall group (r = 0.762, p < 0.001). (4) Conclusions: These findings suggest that CE is an effective intervention to improve gait efficiency, cardiovascular response, and functional capacity in HFpEF patients, whereas HIIT may require further investigation in this population.

Brain endurance training improves sedentary older adults’ cognitive and physical performance when fresh and fatigued

ObjectivesCognitive and physical performance is impaired by aging and fatigue. Cognitive and exercise training may mitigate such impairments. Accordingly, we investigated the effect of Brain Endurance Training (BET) – combined cognitive and exercise training – on cognitive and physical performance when fresh and fatigued in older adults. DesignTwenty-four healthy sedentary women (65–78 years) were randomly allocated to one of three training groups: BET, exercise training, and control (no training). The BET and exercise training groups completed the same physical training protocol comprising three 45-min exercise sessions (20-min resistance exercise plus 25-min endurance exercise) per week for eight weeks. The BET group completed a 20-min cognitive task prior to exercise tasks. Cognitive (tasks: psychomotor vigilance, Stroop) and physical (tests: walk, chair-stand, arm curl) performance was tested when fresh and fatigued (before and after a 30-min cognitive task) at weeks 0 (pre-test), 4 (mid-test), 8 (post-test), and 12 (follow-up test). ResultsCognitive and physical and performance was generally superior when fresh and fatigued at mid-test and post-test for both BET and exercise training groups compared to the control group. The BET group outperformed the exercise group when fatigued at mid-test and post-test both cognitively (always) and physically (sometimes). The pre-to-post changes in cognitive performance when fresh and fatigued averaged 3.7 % and 7.8 % for BET, 3.6 % and 4.5 % for exercise, and −0.4 % and 0.3 % for control groups. The corresponding changes in physical performance averaged 16.5 % and 29.9 % for BET, 13.8 % and 22.4 % for exercise, and 10.8 % and 7.1 % for control groups. ConclusionThese findings show that BET can improve cognitive and physical performance in older adults.

Clemastine enhances exercise-induced motor improvement in hypoxic ischemic rats

Neonatal hypoxic ischemia (HI) occurs owing to reduced cerebral oxygen levels and perfusion during the perinatal period. Brain injury after HI triggers neurological manifestations such as motor impairment, and the improvement of impaired brain function remains challenging. Recent studies suggest that cortical myelination plays a role in motor learning, but its involvement in motor improvement after HI injury is not well understood. This study aimed to investigate the impact of myelination on motor improvement following neonatal HI injury. We employed a modified Rice-Vannucci model; the right common carotid artery of postnatal day 7 (P7) Wistar rats was isolated and divided, and the rats were then exposed to hypoxic condition (90 min, 8 % O2). A total of 101 rats (66 males) were divided into four groups: trained-HI (n = 38), trained-Sham (n = 16), untrained-HI (n = 31), and untrained-Sham (n = 16). The trained groups underwent rotarod-based exercise training from P22 to P41 (3 days per week). Structural analysis using magnetic resonance imaging and immunohistochemistry (n = 6 per group) revealed increased fractional anisotropy and myelin density in the primary somatosensory cortex of the trained-HI group. We further evaluated the effect of myelination promotion on rotarod performance by administering clemastine, a myelination-promoting drug, via daily intraperitoneal injections. Clemastine did not enhance motor improvement in untrained-HI rats. However, clemastine-administered trained-HI rats (n = 7) exhibited significantly improved motor performance compared to both saline-administered trained-HI rats (n = 11) and clemastine-administered untrained-HI rats (n = 7). These findings suggest that myelination may be a key mechanism in motor improvement after HI injury and that combining exercise training with clemastine administration could be an effective therapeutic strategy for motor improvement following HI injury.

Effects of 12 Weeks of Combined Exercise Training in Normobaric Hypoxia on Arterial Stiffness, Inflammatory Biomarkers, and Red Blood Cell Hemorheological Function in Obese Older Women.

The present study examined the effect of 12-week combined exercise training in normobaric hypoxia on arterial stiffness, inflammatory biomarkers, and red blood cell (RBC) hemorheological function in 24 obese older women (mean age: 67.96 ± 0.96 years). Subjects were randomly divided into two groups (normoxia (NMX; n = 12) and hypoxia (HPX; n = 12)). Both groups performed aerobic and resistance exercise training programs three times per week for 12 weeks, and the HPX group performed exercise programs in hypoxic environment chambers during the intervention period. Body composition was estimated using bioelectrical impedance analysis equipment. Arterial stiffness was measured using an automatic waveform analyzer. Biomarkers of inflammation and oxygen transport (tumor necrosis factor alpha, interleukin 6 (IL-6), erythropoietin (EPO), and vascular endothelial growth factor (VEGF)), and RBC hemorheological parameters (RBC deformability and aggregation) were analyzed. All variables showed significantly more beneficial changes in the HPX group than in the NMX group during the intervention. The combined exercise training in normobaric hypoxia significantly reduced blood pressure (systolic blood pressure: p < 0.001, diastolic blood pressure: p < 0.001, mean arterial pressure: p < 0.001, pulse pressure: p < 0.05) and brachial-ankle pulse wave velocity (p < 0.001). IL-6 was significantly lower in the HPX group than in the NMX group post-test (p < 0.001). Also, EPO (p < 0.01) and VEGF (p < 0.01) were significantly higher in the HPX group than in the NMX group post-test. Both groups showed significantly improved RBC deformability (RBC EI_3Pa) (p < 0.001) and aggregation (RBC AI_3Pa) (p < 0.001). The present study suggests that combined exercise training in normobaric hypoxia can improve inflammatory biomarkers and RBC hemorheological parameters in obese older women and may help prevent cardiovascular diseases.

Efficacy of combined exercise training during different menstrual phases in young students with primary dysmenorrhoea

AbstractObjectivesThe objective of the study was to compare the effectiveness of combined exercise training during different menstrual phases on pain, quality of life and menstrual symptoms.MethodsA total of 72 participants for the study were randomly assigned into three groups: Group 1 (N = 24), Group 2 (N = 24) and Group 3 (N = 24) which had undergone combined exercise training during the follicular, luteal and bleeding phases of their menstrual cycle, respectively. The treatment programme included combined exercise training involving deep breathing exercises, Kegel exercises, core strengthening exercises and stretching exercises. Exercises were repeated 5 times with hold duration of 15 s with total of 30–40 min session with 5–10 min of warm‐up and cooldown sessions. Demographic data and outcome measures (Visual Analogue Scale [VAS], Menstrual Symptom Questionnaire [MSQ], and Working ability, Location, Intensity, Days, Duration [WaLIDD]) were assessed at baseline and assessed again during the first menstrual cycle after the completion of the treatment programme. One‐way ANOVA was used for between‐group comparisons of the normally distributed data.ResultsWithin‐group comparison of the outcome variables except VAS in group 3 showed a statistically significant difference in all groups. Comparison of post‐intervention results of the outcome measures of all the groups revealed a statistically significant difference for the VAS, while there was no statistically significant difference for in between the comparison of the WaLIDD and MSQ scoring.ConclusionCombined exercise training is effective in reducing pain only when performed during follicular and luteal phases and significantly improve quality of life and menstrual symptoms in all phases of the menstrual cycle.

Circulating CD31+ Angiogenic T cells are reduced in prediabetes and increase with exercise training

AimsTo investigate circulating angiogenic cells in adults with prediabetes and the effect of a structured exercise program. MethodsA cohort of adults with overweight/obesity and either normal glucose (NG) or prediabetes were randomised to receive exercise (Exercise) (as twice weekly supervised combined high intensity aerobic exercise and progressive resistance training, and once weekly home-based aerobic exercise) or an unsupervised stretching intervention (Control) for 12 weeks. Circulating angiogenic T cells, muscle strength, and cardiovascular disease risk factors, including blood lipids, arterial stiffness, central haemodynamic responses, and cardiorespiratory fitness (VO2peak) in those with prediabetes (n = 35, 16 Control, 19 Exercise) and NG (n = 37, 17 Control, 20 Exercise) were analysed at baseline and after the 12-week intervention. ResultsAt baseline, compared with NG those with prediabetes demonstrated reduced VO2peak, angiogenic CD31+CD8+ T cells and VEGFR2+CD4+ T cells, and increased systolic blood pressure. CD31+ T cells were negatively correlated with cardiovascular disease (CVD) risk. Compared with Control, exercise training increased muscle strength, VO2peak, and CD31+CD4+ and CD31+CD8+ T cells in NG and prediabetes. ConclusionsCirculating angiogenic CD31+ T cells are decreased in people with prediabetes and are enhanced with exercise training. Exercise increases CD31+ T cells, and through this mechanism it is proposed that it may reduce CVD risk.

Effects of aerobic, resistance, and combined exercise training on body fat and glucolipid metabolism in inactive middle-aged adults with overweight or obesity: a randomized trial

MethodTwenty inactive males (BMI 27.67 ± 0.88 kg/m2, age 49.15 ± 2.58 years) participated in an eight-week were randomly assigned to one of three intervention groups (combined (CT), resistance (RT), and aerobic (AT)) exercise modalities to assess within-subject and between group changes in glycolipid profile. Data were analyzed using repeated measures ANCOVA.ResultPre-post mean values of body fat percentage (%BF), area under the curve (AUC), low density lipoprotein (LDL), high density lipoprotein (HDL) and total cholesterol (TC) decreased in all three groups. The main effect of exercise modality on the AUC (F (2, 26) = 10.577, P = 0.001, η2 = 0.569) was significant. Post-hoc analyses revealed that the RT group (-30.653 ± 6.766, p = 0.001) with 11.53% and the CT group (M = -0.896, SE = 3.347, P = 0.015) with 3.79% exhibited significantly greater reductions in AUC compared to the AT group. LDL levels showed significant different between groups (F (2, 26) = 6.33, p = 0.009, η2 = 0.442), specially significantly 3.7% lowered in AT (MD = 4.783, SE = 1.563, P = 0.002) and 3.79% lower in CT (MD = 4.57, SE = 1.284, P = 0.008) groups compared to the RT group. AT significantly reduced TC by 17.716 ± 5.705 mg/dL (p = 0.02) compared to RT, representing a 7.97% decrease.ConclusionExercise type significantly influences lipid profiles and glycemic control. Notably, both aerobic and combined training demonstrated a superior ability to modulate the lipid profile, and resistance training and combined training were more effective in reducing the AUC.Trial registrationMay, 31st 2024.

Improved heart rate variability in postmenopausal women following short-term combined exercise training

Imbalances in cardiac autonomic nervous systems are associated with cardiovascular risk factors and poor cardiac outcomes. Heart rate variability (HRV) is a practical and reproducible measure of cardiac autonomic nervous system function. Exercise training promotes positive adjustments in HRV. However, previous studies have reported mixed results. Therefore, this study aimed to investigate the effects of short-term combined exercise training on heart rate variability in post-menopausal women. Thirty-four women aged 50-80 years, at least 12 months post-menopause, were divided into a control (CON) group and an exercise (EX) training group. The participants in the exercise group underwent a 2-week of combined exercise program consisting of aerobic, strength, flexibility, and balance exercises. HRV was recorded using an Actiheart device, before and after the final exercise intervention in a sitting position. The significant main effects of time and group were found in the parameter of SDNN (p time = 0.039; p group = 0.026). Post-hoc analysis showed a borderline increase in SDNN in the EX group (POST: 48.79 ± 17.88 VS 44.54 ± 17.39, p = 0.055). No significant change was observed in the CON group (POST: 35.55 ± 13.51 VS 33.17 ± 8.74, p = 0.288). Statistical analysis of other HRV components revealed no significant results (all P &gt; 0.05). In conclusion, a 2-week of combined exercise training program, including aerobic, resistance, balance, and flexibility exercises improves global cardiac autonomic function in post-menopausal women.

The Impact of Exercise on C-reactive Protein Levels in Hypertensive Patients: A Systematic Review.

Hypertension, defined as persistently elevated blood pressure, is a prevalent chronic condition and a significant global health issue, closely linked to cardiovascular complications, with inflammation being one of the underlying mechanisms. In hypertensive patients, C-reactive protein (CRP), an inflammatory marker, is often elevated and associated with increased cardiovascular risk. Alongside pharmacotherapy, exercise is recommended as a non-pharmacological approach to managing hypertension, with evidence suggesting that exercise can also reduce inflammation. This study examines the impact of exercise on CRP levels in hypertensive patients. Fourteen studies focusing on exercise interventions and physical fitness related to CRP in individuals with high blood pressure were identified through an extensive search of PubMed, PubMed Central, ScienceDirect, Cochrane Library, and Google Scholar. The findings indicated that most studies involving aerobic exercise consistently demonstrated reductions in CRP levels among hypertensive patients, with significant effects observed under supervised conditions, and additional benefits seen when combined with dietary control. Resistance training showed mixed results, with significant reductions in CRP observed primarily in longer-term interventions. Combined exercise training, incorporating both aerobic and resistance elements, effectively reduced CRP levels and improved cardiovascular health markers. Physical fitness assessments, such as a bicycle exercise test to exhaustion, revealed a relationship between physical fitness and decreased CRP levels. Therefore, regular, consistent aerobic and combined training, as well as prolonged resistance exercise, significantly reduce CRP levels in hypertensive patients, highlighting exercise's role as a non-pharmacological strategy for managing hypertension through the reduction of inflammation. Further research is essential to validate these findings and investigate the underlying mechanisms and differential effects of various exercise modalities.

Effectiveness of Exercise on Fatigue for Patients With Heart Failure: A Systematic Review and Meta-Analysis.

Exercise is the standard treatment for fatigue in heart failure (HF) patients. However, no study has investigated the effect of exercise on improving fatigue and HR-QoL in HF patients. Our study adhered to the Cochrane Handbook for Systematic Reviews of Interventions and followed the PRISMA statement. The date of the last search was October 31, 2021. We included randomized controlled trials (RCTs) using exercise to improve fatigue and HR-QoL. The combined exercise training studies showed improvement in fatigue (SMD = -.51, 95% CI = -.89 to -.12, p = .001, I2 = 48%). The IMT studies showed significantly improved fatigue (MD = -11.36, 95%CI = -15.30 to -7.41, p < .00001, I2 = 54%). However, three studies, with moderate heterogeneity (p = .10, I2 = 56%), showed non-significant changes in HR-QoL (SMD = -0.04, 95% CI = -.45 to .37, p = .83).

Cardiac Rehabilitation for Prediabetes and Metabolic Syndrome Remission: Impact of Ultraprocessed Food–Intake Reduction and Time-Restricted Eating in the DIABEPIC-1 Study

BackgroundCardiac rehabilitation programs provide a valuable opportunity to promote the adoption of healthy lifestyle behaviors in patients with atherosclerotic cardiovascular diseases (ASCVDs) and metabolic comorbidities, including metabolic syndrome and prediabetes. However, strategies to reverse these conditions remain to be explored. The DIABEPIC-1 study aimed to assess the feasibility of an enhanced 6-month cardiac rehabilitation program for patients with ASCVD while investigating prediabetes and metabolic syndrome remission. MethodsThe study combined exercise training with a comprehensive nutritional intervention, emphasizing reduction in intake of ultraprocessed foods, adoption of a Mediterranean diet, and implementation of time-restricted eating. Baseline, 3-month, and 6-month assessments included segmental body-composition measurements, blood analysis, maximal exercise testing, nutritional diaries recorded with the Keenoa AI app, and lifestyle questionnaires. Remission criteria included a return to an HbA1c level of < 5.7%, and < 3 National Cholesterol Education Program Adult Treatment Panel III (NCEP/ATP-III) criteria for prediabetes and metabolic syndrome, respectively. ResultsA total of 36 participants were recruited. The study demonstrated completion rates of 94.4% at 3 months, and 88.9% at 6 months, and a mean compliance rate of 92.5% for planned clinical appointments. Significant reductions in waist circumference (–9.2 cm, P < 0.001) and weight (–8.0 kg, P < 0.001) were observed. Improvement in glycemic and lipid profiles, insulin-resistance marker levels, and liver health were noted. Participants enhanced their cardiorespiratory fitness, reduced their consumption of ultraprocessed food, and increased their adherence to the Mediterranean diet and time-restricted eating. Notably, 50% achieved prediabetes remission, and 70% with metabolic syndrome at baseline achieved remission. ConclusionsThe study demonstrates the possibility of enhancing cardiac rehabilitation with an intensive nutritional intervention, yielding clinically significant outcomes, including remission of key risk factors in a substantial number of ASCVD patients.

Effects of combined aerobic and resistance training on the inflammatory profile of children with overweight/obesity: A randomized clinical trial.

We assessed the effects of a 20-week combined (aerobic and resistance) exercise training programme on the inflammatory profile of prepubertal children with overweight or obesity. Totally 109 participants (10.1 ± 1.1 years, 41% girls) were randomly allocated to an exercise or control group. Adiponectin, C-reactive protein, epidermal growth factor, insulin-like growth factor-1, interleukin (IL)-1β, IL-6, leptin, tumour necrosis factor-α and vascular endothelial growth factor A (VEGFA) were analysed in plasma. Total white blood cell (WBC) count and immune subpopulations (eosinophils, basophils, neutrophils, lymphocytes and monocytes) were also determined. No intervention effect was found for any of the analysed biomarkers (all p ≥ 0.05). We observed a significant sex by intervention interaction for IL-1β (p = 0.03). When stratifying the sample by sex, the exercise programme induced a significant effect on IL-1β levels (mean Z-score difference, 0.66 [95% confidence interval 0.32-1.01]) in girls, but not in boys. A lower number of girls in the exercise group showed a meaningful reduction in IL-1β (i.e., ≥0.2 standard deviations) than in the control group (15% vs. 85%, p = 0.01). This exercise programme failed to improve the inflammatory profile in prepubertal children with overweight/obesity. Future studies should explore the effect of longer exercise interventions and in combination with diet.

Methylome-proteome integration after late-life voluntary exercise training reveals regulation and target information for improved skeletal muscle health.

Exercise is a potent stimulus for combatting skeletal muscle ageing. To study the effects of exercise on muscle in a preclinical setting, we developed a combined endurance-resistance training stimulus for mice called progressive weighted wheel running (PoWeR). PoWeR improves molecular, biochemical, cellular and functional characteristics of skeletal muscle and promotes aspects of partial epigenetic reprogramming when performed late in life (22-24months of age). In this investigation, we leveraged pan-mammalian DNA methylome arrays and tandem mass-spectrometry proteomics in skeletal muscle to provide detailed information on late-life PoWeR adaptations in female mice relative to age-matched sedentary controls (n=7-10 per group). Differential CpG methylation at conserved promoter sites was related to transcriptional regulation genes as well as Nr4a3, Hes1 and Hox genes after PoWeR. Using a holistic method of -omics integration called binding and expression target analysis (BETA), methylome changes were associated with upregulated proteins related to global and mitochondrial translation after PoWeR (P=0.03). Specifically, BETA implicated methylation control of ribosomal, mitoribosomal, and mitochondrial complex I protein abundance after training. DNA methylation may also influence LACTB, MIB1 and UBR4 protein induction with exercise - all are mechanistically linked to muscle health. Computational cistrome analysis predicted several transcription factors including MYC as regulators of the exercise trained methylome-proteome landscape, corroborating prior late-life PoWeR transcriptome data. Correlating the proteome to muscle mass and fatigue resistance revealed positive relationships with VPS13A and NPL levels, respectively. Our findings expose differential epigenetic and proteomic adaptations associated with translational regulation after PoWeR that could influence skeletal muscle mass and function in aged mice. KEY POINTS: Late-life combined endurance-resistance exercise training from 22-24months of age in mice is shown to improve molecular, biochemical, cellular and in vivo functional characteristics of skeletal muscle and promote aspects of partial epigenetic reprogramming and epigenetic age mitigation. Integration of DNA CpG 36k methylation arrays using conserved sites (which also contain methylation ageing clock sites) with exploratory proteomics in skeletal muscle extends our prior work and reveals coordinated and widespread regulation of ribosomal, translation initiation, mitochondrial ribosomal (mitoribosomal) and complex I proteins after combined voluntary exercise training in a sizeable cohort of female mice (n=7-10 per group and analysis). Multi-omics integration predicted epigenetic regulation of serine β-lactamase-like protein (LACTB - linked to tumour resistance in muscle), mind bomb 1 (MIB1 - linked to satellite cell and type 2 fibre maintenance) and ubiquitin protein ligase E3 component N-recognin 4 (UBR4 - linked to muscle protein quality control) after training. Computational cistrome analysis identified MYC as a regulator of the late-life training proteome, in agreement with prior transcriptional analyses. Vacuolar protein sorting 13homolog A (VPS13A) was positively correlated to muscle mass, and the glycoprotein/glycolipid associated sialylation enzyme N-acetylneuraminate pyruvate lyase (NPL) was associated to in vivo muscle fatigue resistance.

As We Were and As We Should Be, Combined Exercise Training in Adults With Schizophrenia: CORTEX-SP Study Part II.

To determine the changes in health-related quality of life (HRQoL) and sleep quality following a supervised combined exercise (EX) program compared to a Treatment-As-Usual (TAU) and to analyze the relationship between the differences in cardiorespiratory fitness (CRF) and HRQoL domains in people with schizophrenia (SZ). The SZ (n = 112, 41.3 ± 10.4 year) was randomly assigned into a TAU control group (n = 53) or EX-group (n = 59, 3 days/week). The 36-item Short-Form Health Survey questionnaire assessed HRQoL and the sleep quality analysis (accelerometry). After the intervention (20 weeks), physical functioning (∆ = 12.9%), general health (∆ = 15.3%), mental health (∆ = 8.3%), physical component summary (PCS) (∆ = 5.1%), and sleep efficiency (∆ = 1.9%) increased (p < 0.05) in the EX, with no significant changes in the TAU for any domains studied. There were significant differences between groups whose EX showed improvements (p < 0.05) compared to TAU in physical functioning, general health, PCS, and sleep efficiency. A greater CRF was associated with better values in physical functioning, role-physical, bodily pain, general health, vitality, and PCS after the exercise program in SZ. A 20-week supervised combined exercise intervention program for SZ increased sleep efficiency and physical functioning, general and mental health, and PCS scores. This could lead to a critical HRQoL change from how they were to how they should be. ClinicalTrials.gov identifier: NCT03509597.

Comparative effects of 8-week combined resistance exercise training and alternate-day calorie restriction on soluble epidermal growth factor receptor (sEGFR) and adipsin in obese men

This study investigated the combined effects of resistance exercise training (RET) and alternate-day calorie restriction (ADCR) on body composition, insulin resistance (IR), insulin resistance-related biomarkers (adipokine adipsin and hepatokine soluble EFGR), and weight loss in obese men. The findings revealed that RET + ADCR induced the greatest reductions in body weight, body fat percentage, and waist-to-hip ratio (WHR) compared to RET and ADCR alone (p < 0.05). Additionally, RET + ADCR resulted in the most significant improvements in IR, as measured by HOMA-IR, and in circulating levels of adipsin and soluble EFGR (p < 0.05). These findings suggest that combining RET and ADCR may be a more effective strategy for improving metabolic health, including body composition, IR, and metabolic tissues’ functions, in obese men than either intervention alone.

Changes in Metabolic and Inflammatory Markers after a Combined Exercise Program in Workers: A Randomized Controlled Trial.

We investigated the effects of a 16-week combined exercise training on body composition, metabolic and inflammatory markers in sedentary middle-aged workers. We also assessed whether significant alterations in metabolic markers were associated with changes in health-related outcomes. This randomized controlled trial involved 46 participants randomly allocated into control and exercise groups. The exercise group performed 16-week combined aerobic and resistance training for 75 min/session, 3 times/week. Fasting blood samples were collected at baseline and after 16-week intervention to determine lipid profile, metabolic and inflammatory markers as primary outcomes. A total of 36 participants completed the intervention (53.70 ± 6.92 years old) (n = 18 in each group). Waist circumference (interaction effect: F = 7.423, p = 0.002), fat mass (interaction effect: F = 5.070, p = 0.011), and muscle mass (interaction effect: F = 5.420, p = 0.007) were improved in the exercise group compared to the control group. Fasting glucose increased after the 16-week follow-up (time effect: F = 73.253, p < 0.001), without an intergroup difference. Insulin levels were greater in the control compared to exercise group (group effect: F = 6.509, p = 0.015). The control group tended to increase the HOMA-IR index (interaction effect: F = 3.493, p = 0.070) and to decrease the QUICKI index (interaction effect: F = 3.364, p = 0.075) to a greater extent compared to the exercise group. Exercise group reduced leptin (interaction effect: F = 11.175, p = 0.002) and adiponectin (interaction effect: F = 4.437, p = 0.043) concentrations in a greater magnitude than control group. IL-6 (time effect: F = 17.767, p < 0.001) and TNF-α (time effect: F = 9.781, p = 0.004) concentrations decreased after the intervention, without an intergroup difference. IL-17A levels increased in the control compared to exercise group (interaction effect: F = 5.010, p = 0.033). Effects on adiponectin, IL-6 and IL-17A levels seem to depend on baseline BMI, age, and sex. Percentage changes in leptin correlated positively with changes in HOMA-IR index in the exercise (r = 0.565, p = 0.015) and control (r = 0.670, p = 0.002) groups. A combined training program can be an effective strategy to improve body composition and inflammatory markers and prevent marked reductions in insulin sensitivity among middle-aged workers.

Efficacy of Lactococcus lactis subsp. lactis LY-66 and Lactobacillus plantarum PL-02 in Enhancing Explosive Strength and Endurance: A Randomized, Double-Blinded Clinical Trial.

Probiotics are posited to enhance exercise performance by influencing muscle protein synthesis, augmenting glycogen storage, and reducing inflammation. This double-blind study randomized 88 participants to receive a six-week intervention with either a placebo, Lactococcus lactis subsp. lactis LY-66, Lactobacillus plantarum PL-02, or a combination of both strains, combined with a structured exercise training program. We assessed changes in maximal oxygen consumption (VO2max), exercise performance, and gut microbiota composition before and after the intervention. Further analyses were conducted to evaluate the impact of probiotics on exercise-induced muscle damage (EIMD), muscle integrity, and inflammatory markers in the blood, 24 and 48 h post-intervention. The results demonstrated that all probiotic groups exhibited significant enhancements in exercise performance and attenuation of muscle strength decline post-exercise exhaustion (p < 0.05). Notably, PL-02 intake significantly increased muscle mass, whereas LY-66 and the combination therapy significantly reduced body fat percentage (p < 0.05). Analysis of intestinal microbiota revealed an increase in beneficial bacteria, especially a significant rise in Akkermansia muciniphila following supplementation with PL-02 and LY-66 (p < 0.05).
