Association of Upper Gastrointestinal Surgery of Great Britain and Ireland (AUGIS)/perioperative quality initiative (POQI) consensus statement on prehabilitation in oesophagogastric surgery.

Prehabilitation is safe, feasible and may improve a range of outcomes in patients with oesophago-gastric cancer (OGC). Recent studies have suggested the potential of prehabilitation to improve body composition, sarcopenia and physical fitness, reduce surgical complications and improve quality of life. Despite this, prehabilitation services are not offered throughout all OGC centres in the UK. Where prehabilitation is offered, delivery and definitions vary significantly, as do funding sources and access. A professional association endorsed series of consensus meetings were conducted using a modified Delphi process developed by the Peri-Operative Quality Initiative (POQI) to identify and refine consensus statements relating to the development and delivery of prehabilitation services for OGC patients. Participants from a variety of disciplines were identified based on a track record of published studies in the field of prehabilitation and/or practice experience encompassing prehabilitation of OGC patients. Approval from the POQI board was obtained and independent supervision provided by POQI. A total of 20 statements were developed and agreed by 26 participants over a preliminary meeting and 2 semi-structured formal POQI meetings. Ten research themes were identified. In the case of one statement, consensus was not reached and the statement was recorded and developed into a research theme. A strong recommendation was made for the majority of the consensus statements (17 of 20). Consensus statements encompassing the interventions and outcomes of prehabilitation services in oesophago-gastric cancer surgery have been developed to inform the implementation of programmes.

Pacing Protein And Plant-based Protein: Predictors Of Improved Body Composition In Division Iii Female Athletes

Biologic and targeted synthetic disease-modifying anti-rheumatic drugs improve body composition in rheumatoid arthritis patients more than conventional synthetic disease-modifying anti-rheumatic drugs: Results from the PRESENT study.

The effects of biologic and targeted synthetic disease-modifying anti-rheumatic drugs (b/tsDMARDs) and conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs) on body composition and muscle function in rheumatoid arthritis (RA) patients requiring treatment enhancement were compared. This multicenter, prospective, observational study (PRESENT Study) divided RA patients non-randomly into a csDMARD group (n = 100) and a b/tsDMARD group (n = 100). Changes in body composition and muscle function were examined in 80 patients in each group followed for 52 weeks. The percentages of new-onset and improved sarcopenia over 1 year were investigated. Patients in the b/tsDMARD group were divided into three groups by drug type: TNF inhibitors (n = 30), non-TNF inhibitors (n = 23), and JAK inhibitors (n = 27). Baseline median age and disease duration were 70.0 and 4.0 years, respectively. Changes in weight (24 and 52 weeks) and muscle mass (52 weeks) were significantly higher in the b/tsDMARD group (p = .035, p < .001, and p = .002, respectively). On multivariate logistic regression analysis, b/tsDMARD treatment (OR 3.21, p = .002), DAS28-ESR (OR 0.65 p = .011), and muscle mass (OR 0.90, p = .023) were independently associated with increased muscle mass at 52 weeks. The percentages of new-onset and improved sarcopenia were almost equal. There were no significant differences in the time-dependent changes (52 weeks) of clinical status, body composition, muscle function, and status of sarcopenia among TNF inhibitors, non-TNF inhibitors, and JAK inhibitors. Weight and muscle mass increased significantly more with b/tsDMARD than with csDMARD treatment. There were no differences in body composition changes by mode of action with b/tsDMARDs.

Effects of 8-weeks Surf Skateboard training on physical fitness in young people

BackgroundSurf skateboards have grown in popularity among young people in recent years. However, no research studies have analyzed the effect of surf skateboarding on physical fitness. ObjectiveThe purpose of this study was to determine the effects of 8-week surf skateboard training on physical fitness in young adults. MethodsTwenty-two young people, ages 18–24 years were randomly assigned into two groups: a control (CON; n = 11) and surf skateboarding (SSK; n = 11) group. The surf skateboard training group received an eight-week intervention consisting of three 60-minute (min) sessions per week, while the control group continued with their normal daily lives. Physical fitness was assessed before and after the intervention through a battery of tests that included body composition, cardiorespiratory fitness, muscular strength and endurance, flexibility, and balance. ResultsThe results showed that the SSK group demonstrated significant (p < 0.05) improvements in maximum voluntary ventilation, back and leg strength, lower body muscular endurance by the sit-to-stand tests, and balance in all direction compared with the pre-test and the CON group. In addition, the SSK group showed significantly (p < 0.05) decreased body weight, body mass index, percent body fat, and resting heart rate, while increased maximum oxygen consumption, pulmonary function, respiratory muscle strength, upper body muscular endurance by the sit-up test and flexibility compared with the pre-test. ConclusionThe findings suggest that surf skateboard training have an effective physical activity intervention to improve body composition, cardiorespiratory fitness, muscular strength and endurance, flexibility, and balance in young people.

Effects of a Sorghum Beverage with Lacticaseibacillus paracasei on Body Composition, Lipid Profiles, and Intestinal Health in Overweight and Obese Adults: A Randomized Single-Blind Pilot Study.

(1) Background: This study aimed to evaluate the effect of an extruded whole-grain sorghum beverage containing L. paracasei on body composition, lipid profiles, and intestinal health in overweight and obese adults. (2) Methods: A chronic, single-blind randomized controlled pilot study was conducted with 30 volunteers allocated to three groups (n = 10/group): extruded sorghum beverage (ESB), extruded sorghum beverage with L. paracasei (ESPB), and control beverage (CB) (waxy maize starch). The chemical composition of the beverages was analyzed. Volunteers consumed the beverages for ten weeks at breakfast, along with individual dietary prescriptions. Body composition, biochemical markers, gastrointestinal symptoms, stool consistency, intestinal permeability, short-chain fatty acids, fecal pH, and stool L. paracasei DNA concentration were analyzed at the beginning and end of the intervention period. (3) Results: The ESB showed better composition than the CB, particularly in terms of resistant starch content, total phenolic compounds, condensed tannins, and antioxidant capacity. Both the ESB and the ESPB had an effect on body composition (estimated total visceral fat and waist volume), biochemical markers (Castelli index I), and intestinal health (Bristol scale, diarrhea score, valeric acid, and L. paracasei DNA concentration). No changes were observed in the CB group after the intervention. (4) Conclusions: Whole-grain sorghum beverages demonstrated good nutritional value, and consumption of these beverages, with or without L. paracasei, provided health benefits, including improvements in body composition, Castelli index I scores, and intestinal health, in overweight and obese adults.

Acute Effects of High-intensity Circuit Training Using Body Weight on Body Composition Indices in Sedentary Collegiate Females

High-intensity circuit training (HICT) has become increasingly popular for enhancing health and fitness. However, limited research exists on the effects of high-intensity circuit training using body weight (HICTBW) on body composition in sedentary young adults. This study aimed to explore the impact of a 4-week HICTBW program on body composition in sedentary collegiate females. A randomized controlled trial design was employed. Twenty sedentary collegiate females were randomly assigned to either a training group (n=10), which participated in a 4-week HICTBW program, or a control group (n=10), which did not engage in any training. Body composition was assessed using bioelectrical impedance analysis (r = 0.642 to 0.78), measuring body fat percentage, fat mass, muscle mass, waist-to-hip ratio, and body mass index (BMI). Repeated measure ANOVA was used to compare between and within groups. Although no significant differences in body composition variables were observed between pre- and post-training (p&amp;gt;0.05), slight positive changes were noted in all measured parameters. The lack of significant findings may be attributed to the short duration and frequency of the intervention. Future studies with extended training periods are recommended to better understand the potential impact of HICTBW on body composition in sedentary collegiate females. This research highlights the need for more comprehensive studies to validate the effectiveness of HICTBW in improving body composition among this population.

Abstract A088: Examining associations between objective and perceived stress and allostatic load in African American prostate cancer survivors

Abstract Background. Racial disparities in prostate cancer survivorship persist despite clinical advancements. Stress has been implicated as a potential driver of these disparities, with both chronic and perceived stress found to be associated with adverse cancer survivorship. Allostatic load (AL), one such marker of chronic stress, has been associated with decreased survivorship and worse quality of life (QoL) in cancer survivors. Perceived stress has also been associated with outcomes in cancer survivorship including increased symptom burden and worse quality of life. Despite this, few studies incorporate direct measures of stress or examine how these measures contribute to AL This study examines the relationship between AL, objective stress (as measured by occurrence of stressful life events), and self-reported perceived stress in a subset of African American prostate cancer survivors (N=59) enrolled in Men Moving Forward, a randomized trial to improve body composition through lifestyle change. Methods. At baseline, participants completed an adapted version of the Crisis in the Family Systems (CRISYS) survey, an instrument designed to measure recent (past 4 months) contemporary life stressors. The survey was tailored for AAPCS via feedback from the community advisory board. 41 items reflective of 11 domains were included. Overall CRISYS scores and scores by domain were calculated. Feelings of perceived stress in the past month were measured via the 10-item perceived stress scale, with higher scores reflecting higher perceived stress. AL scores used 15 criterion reflecting neuroendocrine, cardiovascular, immune, and metabolic systems. Each criterion was assigned a score of 0 or 1: 1 if in the high-risk range based on clinical guidelines. An index score was generated by summing high-risk indicators. Pearson correlations were used to explore the relationship between stress measures. Logistic regression comparing the those with highest quartile AL to lower AL was also performed. Results. The mean AL score was 5.6 (SD ± 2.4) of a maximum score of 15. The mean summative score for CRISYS was 4.8 (SD ± 3.3). The most common domains of stress experienced were safety in the community (67%), relationships (66%), and medical issues of loved ones (44%). The Mean PSS was 11.5 (SD ± 6.0), with 64% of men reporting low stress and 36% moderate stress levels. Significant correlations were found between CRISYS and PSS, however no correlations with AL were detected. No significant findings were identified in the regression analysis. Conclusions. Objective and perceived stress measures were correlated, but no associations were found between the perceived or objective stress measure and AL in this sample.. Given AL is meant to reflect the physiological impact of cumulative and chronic stress burdens, it is possible that the shorter-term context of the objective (past 4 months) and perceived stress (past month) measures were not sufficiently aligned with the longer-term context of AL.

Body composition in a pediatric population with type-1 diabetes – The importance of planned physical exercise

Objective and methodsThis study aimed to assess the body composition of pediatric patients with type-1 diabetes (T1D) in a Portuguese pediatric endocrinology/diabetic clinic, using the InBody 570 bioimpedance system. Preschool children (<6 years) and those recently diagnosed (<6 months) were excluded. ResultsThe study included 78 patients (53% female). Median age at assessment was 14 years, with 81% pubertal children. Eighty-seven percent were using continuous subcutaneous insulin infusion (CSII), 25% with an automated closed-loop model. Median HbA1c was 7.3%. Most had an adequate body mass index (BMI) standard deviation score (62%) and 48% engaged in regular physical exercise (PE) outside of school. Median percentage body fat (PBF) was 21.5% and was abnormal in 48%, with median visceral adiposity of 4. Despite adequate BMI, 11% had excessive PBF. PBF was significantly associated with visceral fat (r=0.79; P<0.001), female gender (P<0.001) and PE performed out of school (P=0.005). PE was associated with lower PBF (P=0.005), lower visceral fat (P=0.002), and higher muscle-to-fat ratio (P=0.006). ConclusionEngaging in physical exercise out of school correlated significantly with improved body composition, characterized by reduced PBF and diminished visceral adiposity. Considering the known benefits of physical exercise for metabolic and glycemic control, this study highlights the importance of promoting regular physical exercise in T1D patients.

Synergistic Effects of Time-Restricted Feeding and Resistance Training on Body Composition and Metabolic Health: A Systematic Review and Meta-Analysis.

This systematic review and meta-analysis examined the synergistic impact of time-restricted feeding (TRF) combined with resistance training (RT) (TRF + RT) on body composition and metabolic health in adults, contrasting it with habitual eating patterns (CON) and RT (CON + RT). Adhering to PRISMA guidelines, five databases were searched up to 28 April 2024. Randomized controlled trials or crossover trials assessing the effects of TRF + RT for at least 4 weeks in adults were selected. Data were pooled as standardized mean differences (SMDs) or weighted mean differences (WMDs) with 95% confidence intervals (CIs). The risk of bias was evaluated using the revised Cochrane risk-of-bias tool. Seven studies with 164 participants were included in the final analysis. TRF + RT significantly reduced body mass (WMD -2.90, 95% CI: -5.30 to -0.51), fat mass (WMD -1.52, 95% CI: -2.30 to -0.75), insulin (SMD -0.72, 95% CI: -1.24 to -0.21), total cholesterol (WMD -9.44, 95% CI: -13.62 to -5.27), low-density lipoprotein cholesterol (LDL-C) (WMD -9.94, 95% CI: -13.47 to -6.41), and energy intake (WMD -174.88, 95% CI: -283.79 to -65.97) compared to CON + RT. No significant changes were observed in muscle mass, strength, or other metabolic markers. TRF + RT, in contrast to CON + RT, significantly improved body composition, insulin, and cholesterol levels without affecting muscle mass or strength.

Testosterone and the prevention of type 2 diabetes mellitus: therapeutic implications from recent trials.

Type 2 diabetes (T2D) is increasing to epidemic proportions and frequently associated with obesity and a low serum testosterone concentration in men. This review valuates recent randomized controlled trials (RCTs) investigating the effect of testosterone treatment on glycemic control and T2D prevention. The 2-year Testosterone for the Prevention of Type 2 diabetes Trial (T4DM) study showed that in men aged 50 years and over with visceral obesity and impaired glucose tolerance, testosterone treatment on the background of a lifestyle intervention reduced T2D risk by 40%. The Testosterone Effects on Atherosclerosis Progression in Aging Men and Testosterone Trials demonstrated modest improvements in insulin sensitivity and body composition. However, the Testosterone Replacement Therapy for Assessment of Long-Term Vascular Events and Efficacy Response in Hypogonadal Men trial found no significant glycemic benefits over 2 years. Recent data from the Diabetes Prevention Program Outcome Study support the cost efficacy and durability of metformin. In men at high risk of T2D, treatment with testosterone prevents the disease; however, there are caveats to its use and other approaches may be more applicable. Differences in trial designs, age groups, and outcome measures contribute to varying results. HbA1C is a suboptimal outcome measure. Future research should explore potential synergies between testosterone and GLP-1 receptor agonists in T2D management, while considering cost-effectiveness.

Effects of 12-weeks resistance training and vitamin E supplementation on aminotransferases, CTRP-2, and CTRP-9 levels in males with nonalcoholic fatty liver disease: a double-blind, randomized trial

BackgroundNonalcoholic fatty liver disease (NAFLD) involves excessive liver fat accumulation and is closely linked to oxidative stress, which contributes to liver inflammation and damage. This study aimed to evaluate how interventions such as resistance training (RT) and vitamin E supplementation (VES) can modulate markers of NAFLD and key proteins regulating glucose and lipid metabolism, such as C1Q/TNF-related proteins (CTRPs).MethodsForty participants with NAFLD (mean age: 32.4 ± 8.2 years) were randomly assigned to one of four groups for 12 weeks: placebo (PLB), VES, PLB + RT, and VES + RT. VES was administered at 800 IU/day in a double-blind manner. The RT regimen included eight exercises at 60–80% of one-repetition maximum (1RM), with three sets of 8–12 repetitions, performed three times per week. Pre- and post-intervention assessments included body composition, aspartate aminotransferase (AST), alanine aminotransferase (ALT), lipid profile, glycemic control, CTRP-2, CTRP-9, and 1RM evaluations.ResultsFollowing the interventions, there was a significant improvement in body composition, lipid profile, glycemic control, and 1RM indices in the exercise groups compared to non-exercise groups (p < 0.05). AST and ALT levels decreased in all groups (p < 0.05) compared to the PLB group. There was also a significant difference between the VES + RT group and both the VES and PLB + RT groups (p < 0.05). CTRP-2 and CTRP-9 levels decreased in the exercise groups compared to non-exercise groups (p < 0.05), and their changes showed a marked correlation with body composition, lipid profile, and glycemic control indices (p < 0.05).ConclusionsThis study highlights the benefits of RT on various health parameters among NAFLD patients. While adding VES to RT resulted in greater decreases in aminotransferases, it did not provide further improvements in other variables. Additionally, enhancements in body composition, lipid profile, and glycemic control indices were possibly associated with decreased levels of CTRPs.Trial registrationRegistered retrospectively in the Iranian Registry of Clinical Trials (IRCT20220601055056N1) on December 21, 2023.

Developing an 8-Week, Tele-Education Weight Control and Exercise Programme, and Evaluating Its Effects on Weight and Pain Reduction in Patients With Obesity and Knee Osteoarthritis: A Double-Blinded Randomised Clinical Trial.

Knee osteoarthritis (OA) is a leading cause of disability among the elderly and is often exacerbated by obesity. Research supports weight loss and exercise therapy as key strategies for managing knee OA-related disability. Concurrently, telemedicine is becoming a popular healthcare approach. This study aimed to develop and evaluate an 8-week tele-education programme's impact on weight control and knee OA outcomes. Participants with knee OA and obesity were included. Baseline data on pain (VAS index), physical activity (GPAQ questionnaire), and quality of life (EQ5D and KOOS questionnaires) were collected. Performance tests, including the 30-second Chair Stand test (30CST) and the Timed Up-and-Go test (TUG), were recorded. Participants were randomly divided into two groups: a control group receiving oral advice on diet and exercise, and an intervention group receiving educational videos on nutrition, lifestyle changes, physical activity, individualised exercises, and psychosocial support. Evaluations were repeated after 8weeks. Data from 25 of 30 participants were analysed. In the intervention group, body composition, waist, and abdominal circumference decreased significantly (p<0.05). The KOOS questionnaire showed significant improvements in pain, activity, and daily tasks (p=0.00). The EQ5D questionnaire and health satisfaction also showed positive results within the intervention group (p=0.00) and between groups (p=0.008). The pain index improved significantly within (p=0.00) and between groups (p=0.02). Functional test results were significant within the intervention group (p=0.00) and between groups (p=0.017 for 30CST and p=0.004 for TUG). An 8-week tele-education programme for weight control and exercise therapy in knee OA patients significantly improved body composition, quality of life, and functional performance. Given the costs of obesity and knee OA on both people and the health system, tele-education can be a cost-effective treatment strategy.

Effect of Diet, Exercise and Sleep (DES) Model in Six Months Postpartum Weight Retention and Body Composition in Thai Mothers: A Quasi-Experimental Study

ms: The amount of fatty tissue in women increases during pregnancy, leading to postpartum weight retention after delivery. Thus, pregnancy has been identified as a stimulus leading to the development of overweight and obesity. This study investigates the effect of the diet, exercise and sleep (DES) model on weight retention and body composition among Thai mothers six months to one year post-delivery. Methods: A total of 64 participants were allocated to the intervention and control groups. The intervention group received health education and a Pilates exercise programme in the first month, which they practiced in months 2–6. During this time, the researchers visited their homes each month, counselling the women based on the transtheoretical model. This research had two primary outcome measures, including after-delivery weight retention and body composition, and three secondary outcome measures, including knowledge, attitudes and practices related to diet, exercise and sleep. The measures were collected at baseline and every month using a questionnaire and body composition analysis. Data were analysed using a t-test and repeated measures ANOVA. All levels of significance were set as p &lt; 0.05. Result: A comparison of postpartum weight retention six months and one year after delivery in the intervention group showed that the mothers’ weight decreased significantly. Body fat and visceral fat levels significantly decreased after participating in the programme for six months. In addition, postpartum weight retention and body composition in the intervention group were significantly better than in the control group one year after delivery. Conclusions: Postpartum weight retention is associated with long-term maternal morbidity. The intervention significantly reduced postpartum weight retention and improved body composition. Therefore, this model may be used in planning the development of maternal health behaviours in the postpartum period.

Effects of insect consumption on exercise performance, body composition and metabolism: a review

Abstract Insects contain a number of beneficial macronutrients, micronutrients, and bioactive compounds that play crucial roles for optimal bodily functions and exercise. This review aims to consolidate information from studies involving humans and animals that investigated the effect of insect consumption, either alone or in combination with exercise, on exercise performance, body composition, and metabolism. In humans, insect supplementation with exercise could improve strength. Insect supplementation, with or without exercise, could also improve body composition. However, the lack of dietary and physical activity control may have influenced these findings. Insect consumption alone caused increased blood amino acids, followed by activation of the mammalian target of rapamycin complex-1 (mTORC1) signalling and increased muscle protein synthesis, which is further elevated when combined with resistance exercise. In animals, insect consumption alone could improve endurance and fatigue biomarkers. It could also reduce fat mass and increase muscle mass. The reduction in fat mass was attributed to improvements in blood lipid profiles, while the increase in muscle mass is attributed to elevated blood amino acids and mTORC1. Interestingly, in combination with exercise, greater changes in these variables were observed, including increases in energy metabolism. Findings from animal studies, such as changes in muscle mass and protein metabolism, have been validated in humans, while outcomes regarding endurance, fat mass, and blood lipids have not been validated in humans. This encourages future research to focus on these parameters. Due to ethical constraints and impracticality, there has been a reliance on animal studies to elucidate certain mechanisms and parameters in humans. Overall, insect consumption, with or without exercise, in both humans and animals showed promising results in improving exercise performance, body composition, and metabolism and thus, could function as an alternative exercise supplement. Additionally, utilizing animal models has allowed researchers to better understand the key mechanisms behind these improvements.

Association Between Body Composition Patterns, Cardiovascular Disease, and Risk of Neurodegenerative Disease in the UK Biobank.

Accumulating evidence connects diverse components of body composition (e.g., fat, muscle, and bone) to neurodegenerative disease risk, yet their interplay remains underexplored. This study examines the associations between patterns of body composition and the risk of neurodegenerative diseases, exploring the mediating role of cardiovascular diseases (CVDs). This retrospective analysis used data from the UK Biobank, a prospective community-based cohort study. We included participants free of neurodegenerative diseases and with requisite body composition measurements at recruitment, who were followed from 5 years after recruitment until April 1, 2023, to identify incident neurodegenerative diseases. We assessed the associations between different components and major patterns of body composition (identified by principal component analysis) with the risk of neurodegenerative diseases, using multivariable Cox models. Analyses were stratified by disease susceptibility, indexed by polygenetic risk scores for Alzheimer and Parkinson diseases, APOE genotype, and family history of neurodegenerative diseases. Furthermore, we performed mediation analysis to estimate the contribution of CVDs to these associations. In addition, in a subcohort of 40,790 participants, we examined the relationship between body composition patterns and brain aging biomarkers (i.e., brain atrophy and cerebral small vessel disease). Among 412,691 participants (mean age 56.0 years, 55.1% female), 8,224 new cases of neurodegenerative diseases were identified over an average follow-up of 9.1 years. Patterns identified as "fat-to-lean mass," "muscle strength," "bone density," and "leg-dominant fat distribution" were associated with a lower rate of neurodegenerative diseases (hazard ratio [HR] = 0.74-0.94) while "central obesity" and "arm-dominant fat distribution" patterns were associated with a higher rate (HR = 1.13-1.18). Stratification analysis yielded comparable risk estimates across different susceptibility groups. Notably, 10.7%-35.3% of the observed associations were mediated by CVDs, particularly cerebrovascular diseases. The subcohort analysis of brain aging biomarkers corroborated the findings for "central obesity," "muscle strength," and "arm-dominant fat distribution" patterns. Our analyses demonstrated robust associations of body composition patterns featured by "central obesity," "muscle strength," and "arm-dominant fat distribution" with both neurodegenerative diseases and brain aging, which were partially mediated by CVDs. These findings underscore the potential of improving body composition and early CVD management in mitigating risk of neurodegenerative diseases.

A comparison of continuous, interval, and accumulated workouts with equalized exercise volume: excess post-exercise oxygen consumption in women

BackgroundDespite the well-known health benefits of exercise, women’s participation in exercise is low worldwide. As women are at risk of developing various chronic diseases as they age, suggesting effective exercise methods that can maximize energy consumption is needed to prevent such conditions. Excess post-exercise oxygen consumption (EPOC) can maximize energy consumption. In this crossover, randomized controlled trial, we aimed to compare the EPOC for different exercise modalities including continuous exercise (CE), interval exercise (IE), and accumulated exercise (AE) that spent the homogenized energy expenditure during exercise in healthy women.MethodsForty-four participants (age, 36.09 ± 11.73 years) were recruited and randomly allocated to three groups. The intensity of each modality was set as follows: CE was performed for 30 min at 60% peak oxygen uptake (VO2peak). IE was performed once for 2 min at 80% VO2peak, followed by 3 min at 80% VO2peak, and 1 min at 40% VO2peak, for a total of six times over 26 min. AE was performed for 10 min with a 60% VO2peak and was measured thrice a day.ResultsDuring exercise, energy metabolism was higher for IE and CE than that for AE. However, this was reversed for AE during EPOC. Consequently, the greatest energy metabolism was shown for AE during total time (exercise and EPOC).ConclusionsBy encouraging regular exercises, AE can help maintain and improve body composition by increasing compliance with exercise participation, given its short exercise times, and by efficiently increasing energy consumption through the accumulation of EPOC.Trial registrationClinical number (KCT0007298), 18/05/2022, Institutional Review Board of Konkuk University (7001355-202201-E-160).

Shift schedule effects on firefighter health and fitness.

Firefighter health is of utmost importance both to first responders and the individuals they serve daily. The impact of shift schedule on firefighter health remains poorly understood. The purpose of this study was to examine differences in health and performance outcomes in firefighters across two different shift schedules. Firefighter (N = 1995) body composition, muscular strength, endurance, flexibility, and cardiorespiratory endurance were assessed and described. A Mann-Whitney U test was conducted to compare differences between shift schedules (48/96 and 4's and 6's). There was a statistically significant difference in BMI (U = 70115, z=-1.988, p = .047), BF% (U = 67341, z=-2.779, p = .005), and trunk flexion score (U = 81362, z = 1.979, p = .048) favoring the 48/96 shift schedule. Firefighters following a 48/96 shift schedule exhibited improved body composition and fitness performance in comparison to peers who followed a 4's and 6's shift schedule. Findings may guide regional firefighter scheduling to optimize health and performance.

Impact of concurrent training sequence on heart rate variability, glycemic control, body composition, lipid profile, and cardiorespiratory fitness in type 2 diabetes patients with cardiac autonomic neuropathy: A randomized controlled trial

BackgroundType 2 Diabetes Mellitus (T2DM) is a global health concern, with cardiac autonomic neuropathy (CAN) being a significant complication that exacerbates cardiovascular risks. Aerobic and resistance exercises are recognized for their benefits in managing T2DM, but the optimal integration of these modalities, especially for patients with T2DM, requires further exploration. ObjectiveTo investigate the effects of the sequence of aerobic and resistance training in a concurrent training regimen on heart rate variability (HRV), glycemic control, body composition, lipid profile, and cardiorespiratory fitness (CRF) in patients with T2DM. MethodsIn this randomized controlled trial, 45 T2DM patients with CAN were allocated to three groups: a control group, an aerobic then resistance training (ART) group, and a resistance then aerobic training (RAT) group. Measurements were taken at baseline and after a 13-week intervention, assessing HRV, glycemic control, body composition, lipid profile, and CRF. ResultsBoth ART and RAT groups showed significant improvements in HRV, glycemic control, body composition, lipid profile, and CRF compared to the control group. Notably, there were no significant differences between ART and RAT groups in these outcomes, suggesting that the sequence of aerobic and resistance exercises in concurrent training does not significantly affect the health benefits attained. ConclusionConcurrent aerobic and resistance training, irrespective of the sequence, effectively improves HRV, glycemic control, body composition, lipid profile, and CRF in T2DM patients with CAN. This study supports the inclusion of concurrent training in exercise prescriptions for managing T2DM and its complications.

Nondietary psychological app program leads to sustained weight loss due to trained physiological satiety perception.

Obese people are mostly unable to maintain successful weight loss after the end of a dietary change. One reason is that conventional weight reduction concepts neglect physiological hunger and satiety perception, leading to a relapse to previous eating habits on the long run. We examined the long-term efficacy of a psychological smartphone weight loss program, which avoids any dietary instructions and aims at relearning of satiety perception. Parameters of body weight alterations and psychological features, for example, satiety perception, food cravings, and emotional eating, were explored in a nonrandomized experimental study comprising 75 obese participants. Measurements occurred at baseline, two times during program application, as well as at 6- and 12-month follow-up. Participants displayed significant weight loss during the entire study period (p = .029) and showed an improved body composition at the 6-month follow-up (p = .018). These effects were associated with increased satiety perception, as well as reduced food cravings, and emotional eating habits. Notably, all improvements in measured parameters significantly sustained between the end of the program and the 12-month follow-up (p < .005 for all). Psychological relearning of satiety perception may outclass dietary approaches in terms of long-term efficiency.

Efficacy of Supersets Versus Traditional Sets in Whole-Body Multiple-Joint Resistance Training: A Randomized Controlled Trial.

Iversen, VM, Eide, VB, Unhjem, BJ, and Fimland, MS. Efficacy of supersets versus traditional sets in whole-body multiple-joint resistance training: A randomized controlled trial. J Strength Cond Res 38(8): 1372-1378, 2024-Time constraints often hinder exercise engagement, necessitating exploration of time-efficient resistance training methods. Superset training, where 2 exercises are performed successively with minimal rest, nearly halves session duration but is metabolically demanding, possibly reducing strength gains. In a randomized controlled trial with blinded test leaders, we examined the efficacy of supersets versus traditional sets in a full-body, multiple-joint resistance training workout on maximal strength in the trained exercises. Subjects took part in a 3-week introductory training phase before baseline testing to ensure they were thoroughly familiarized. Next, they were randomized to a superset- or a traditional-set group, performing 10 weeks of heavy multiple-joint resistance training twice per week. The exercise programs consisted of leg press, bench press, lat pull-down, and seated rows. The traditional training group had a 5.2-kg higher improvement in pull-down than the superset group (p = 0.033), and a close to significant 4.8-kg higher improvement in seated rows (p = 0.073). The improvements in leg press and bench press were quite similar for both groups (p = 0.507-0.527). There were no changes between groups in body composition outcomes (0.151-0.640), but both groups increased muscle mass and reduced fat mass (p < 0.05). In conclusion, superset training of multi-joint exercises hampered maximal strength gains somewhat compared with traditional-set training. However, there were very similar improvements in body composition, and strength gains were observed for all exercises in the superset group. Thus, whole-body, multiple-joint superset resistance training could be a viable time-saving approach.
