Background: Daily nutrition plays an important role in supporting training adaptions and endurance performance. The objective of this 10-week study was to investigate the consequences of varying carbohydrate consumption and the glycaemic index (GI) together with an endurance training regimen on substrate oxidation, muscle energy storage and endurance performance under free-living conditions. Sixty-five moderately trained healthy men (29 ± 4 years; VO
2 peak 55 ± 8 mL min−1 kg−1 ) were randomized to one of three different nutritional regimes (LOW-GI: 50–60% CHO with ≥ 65% of these CHO with GI < 50 per day, n = 24; HIGH-GI: 50–60% CHO with ≥ 65% CHO with GI > 70 per day, n = 20; LCHF: ≤ 50 g CHO daily, n = 21). Metabolic alterations and performance were assessed at baseline (T0) and after 10 weeks (T10) during a graded exercise treadmill test. Additionally, a 5 km time trial on a 400-m outdoor track was performed and muscle glycogen was measured by magnet resonance spectroscopy. Results: Total fat oxidation expressed as area under the curve (AUC) during the graded exercise test increased in LCHF (1.3 ± 2.4 g min−1 × km h−1 , p < 0.001), remained unchanged in LOW-GI (p > 0.05) and decreased in HIGH-GI (− 1.7 ± 1.5 g min−1 × km h−1 , p < 0.001). After the intervention, LOW-GI (− 0.4 ± 0.5 mmol L−1 × km h−1 , p < 0.001) and LCHF (− 0.8 ± 0.7 mmol L−1 × km h−1 , p < 0.001) showed significantly lower AUC of blood lactate concentrations. Peak running speed increased in LOW-GI (T0: 4.3 ± 0.4 vs. T10: 4.5 ± 0.3 m s−1 , p < 0.001) and HIGH-GI (T0: 4.4 ± 0.5 vs. T10: 4.6 ± 0.4 m s−1 ), while no improvement was observed in LCHF. Yet, time trial performance improved significantly in all groups. Muscle glycogen content increased for participants in HIGH-GI (T0: 97.3 ± 18.5 vs. T10: 144.5 ± 39.8 mmol L wet-tissue−1 , p = 0.027) and remained unchanged in the LOW-GI and the LCHF group. At the last examination, muscle glycogen concentration was significantly higher in LOW-GI compared to LCHF (p = 0.014). Conclusion: Changes in fat oxidation were only present in LCHF, however, lower lactate concentrations in LOW-GI resulted in changes indicating an improved substrate metabolism. Compared to a LCHF diet, changes in peak running speed, and muscle glycogen stores were superior in LOW- and HIGH-GI diets. The low GI diet seems to have an influence on substrate metabolism without compromising performance at higher intensities, suggesting that a high-carbohydrate diet with a low GI is a viable alternative to a LCHF or a high GI diet. Trial registration: Clinical Trials, NCT05241730. https://clinicaltrials.gov/study/NCT05241730. Registered 25 January 2021. Key Points: While only the LCHF diet showed an improvement in fat oxidation and the HIGH-GI group increased peak running speed and showed a trend towards an improvement in time to exhaustion, the LOW-GI group appears to combine both effects on substrate metabolism and performance. Administered under free-living conditions, energy intake changed in LOW-GI diet, possible due to higher intake of fibre, stable insulin levels and associated higher feeling of satiety. Energy intake in HIGH-GI showed no changes and in LCHF a trend towards a reduced intake was observed. While changes in body weight and composition were more pronounced in LOW-GI and LCHF group, muscle energy storage showed beneficial improvements in endurance runners on a high glycaemic index diet. With the muscle glycogen content being significantly lower in LCHF compared to LOW-GI group, it can be assumed that this might be a limiting factor in maximum values for the graded exercise test.

Background: First evidence indicates that the supplementation of specific collagen peptides (SCP) is associated with a significant improvement in running performance in physically active women; however, it is unclear if the same is true in males. The purpose of the present study was to investigate the effects of a concurrent training program including 60 min of continuous moderate intensity running training and 15 min of dynamic resistance training combined with supplementation of SCP on parameters of running performance in moderately trained males. Methods: In a double-blind, placebo-controlled, randomized trial, participants performed a 12 weeks concurrent training and ingested 15 g of SCP [treatment group (TG)] or placebo [control group (CG)] daily. Before and after the intervention, running endurance performance was measured by a 1-h time trial on a running track. Velocity at the lactate threshold (V
LT ) and at the individual anaerobic threshold (VIAT ) were assessed on a treadmill ergometer. Body composition was evaluated by bioelectrical impedance analysis. Results: Thirty-two men (28.4 ± 5.2 years) completed the study and were included in the analysis. After 12 weeks, TG had a statistically significant (p ≤ 0.05) higher increase in running distance (1727 ± 705 m) compared to the CG (1018 ± 976 m) in the time trial. VLT increased in the TG by 0.680 ± 1.27 km h−1 and slightly decreased by − 0.135 ± 0.978 km h−1 in the CG, resulting in statistically significant group differences (p ≤ 0.05). A significantly higher improvement in VIAT (p ≤ 0.05) was shown in the TG compared with the CG only (1.660 ± 1.022 km h−1 vs 0.606 ± 0.974 km h−1 ; p ≤ 0.01). Fat mass decreased (TG − 1.7 ± 1.6 kg; CG − 1.2 ± 2.0 kg) and fat free mass increased (TG 0.2 ± 1.2 kg; CG 0.5 ± 1.3 kg) in both groups with no significant group differences. Conclusion: In summary, supplementation with 15 g of SCP improved running performance in a 1-h time trial and enhanced indicators of endurance capacity at submaximal exercise intensities such as an increased velocity at the lactate as well as the anaerobic threshold more effectively than CT alone.

- Abstract
Summary: Background: In response to the current coronavirus disease 2019 (COVID-19) pandemic the Austrian government issued a lockdown from 16 March to 15 May 2020. As periods of economic and emotional burden have proven to detrimentally affect people's psychological health, healthcare officials warned that the strict measures could have a serious impact on psychological health, leading to an increase in suicide attempts. Thus, the objective was to provide evidence for this assumption. Methods: All adult patients admitted to the trauma resuscitation room of the Medical University of Vienna during the lockdown period following a suicide attempt were included in this analysis, forming the study group. Suicidal patients treated during the same period in 2015, 2016, 2018, and 2019 were pooled to create the control group. The year 2017 was excluded because another major hospital in Vienna was partially closed due to a change in infrastructure, resulting in an increased number of severely injured patients treated at our department. As the lockdown caused a markedly decreased number of patients admitted due to other reasons than suicide the actual number was replaced with the average number of patients admitted in the relevant previous 4 years. Results: By comparing the study and the control group based on this realistic estimate we revealed an increase in attempted suicides during the lockdown period (p = 0.001). Demographic, mental health-related, and injury specific patient data did not differ between the groups. Conclusion: The results strongly urge for an improvement in crisis intervention and suicide prevention measures in the event of a future lockdown. [ABSTRACT FROM AUTHOR]

- Abstract
Summary: Background: This study investigated the impact of curative breast cancer surgery on patient satisfaction concerning cosmetic results and quality of life (QoL). Methods: In this study 61 participants completed questionnaires to evaluate their QoL and patient satisfaction with cosmetic results following breast cancer surgery. Cosmetic outcomes were evaluated by the breast surgeon and an independent breast specialist using the Harris scale and the breast analyzing tool (BAT). Results: Of the participants 71% completed all 4 follow-up visits, 38 (62%) patients received breast-conserving therapy (BCT) and 23 (38%) received a mastectomy. Surgery-associated complications arose in 2.6% of the patients who received BCT and 17.4% of patients who received a mastectomy. No significant differences in QoL between BCT patients and mastectomy patients were observed immediately after surgery, or after 6 and 12 months. Breast asymmetry, measured using the BAT score, and QoL scores were worst immediately after surgery. The surgeon rated the cosmetic results as better compared to the independent breast expert (p = 0.001). Furthermore, patients aged over 60 years old were less satisfied with the cosmetic outcome compared to younger patients at the time of discharge (p = 0.024). Patients who received a mastectomy were less satisfied when the resected volume was higher. Conclusion: Patient satisfaction was lowest immediately after surgery but improved during the following months, despite continued breast asymmetry. For mastectomy patients, a lower resected volume led to a higher satisfaction with cosmetic results. Satisfaction is subjective and cannot be determined from the esthetic satisfaction of the surgeon or using an objective tool measuring breast asymmetry. [ABSTRACT FROM AUTHOR]

Purpose: Whole-body vibration (WBV) training is frequently applied in sports and rehabilitation with the aim of inducing beneficial functional and structural adaptations. In the past decades, blood flow restriction (BFR) training has received increasing attention by enhancing the effectiveness of several low-load exercise regimens. The objective of this study was to evaluate the additional effect of BFR on myoelectric activity and metabolic accumulation during WBV training.Methods: Fifteen active men performed three sessions in a counterbalanced order on three different days: whole-body vibration exercise (WBV), whole-body vibration exercise with blood flow restriction (WBV + BFR), and a control session (CON) with neither WBV nor BFR. Electromyographic (EMG) activity was measured in six lower limb muscles throughout each exercise session; lactate and reactive oxygen species (ROS) concentrations were determined prior to, immediately after and 15 min after the exercise sessions.Results: EMG amplitudes increased from CON (29 ± 13% MVC) to WBV (45 ± 20% MVC) to WBV + BFR (71 ± 37% MVC) conditions (p < 0.05). Likewise, lactate concentrations increased in a similar manner, demonstrating significantly higher increases in the WBV + BFR session compared to WBV and CON. Furthermore, significant correlations between lactate concentration and EMG amplitude were detected. ROS concentration did not change significantly between the conditions.Conclusions: The findings of the present study emphasize that the addition of BFR increases the acute effects beyond WBV treatment alone which becomes manifested in both neuromuscular and metabolic adaptations. Further research is needed to identify potential long-term effects of the combination of these two training regimens. [ABSTRACT FROM AUTHOR]- Published

Attitudes towards psychiatric medication are an important factor influencing the success of treatment. Mental health care in the region of Central and Eastern Europe remains biologically oriented, yet the attitudes of people with severe mental illnesses are largely unknown. In the present study, we aimed to analyze factors of attitudes toward psychopharmacological drugs among people with schizophrenia spectrum disorder who use community social services in the Czech Republic. Drug Attitude Inventory (DAI) was used as a primary research instrument and data were analyzed using a multivariable linear regression. The majority of respondents (78%) had positive attitudes towards psychopharmacological treatment. Additionally, attitudes towards psychopharmaceutic drugs did not differ with regard to sociodemographic characteristics except for family status. There was a significant negative correlation with the level of self-stigmatization and a significant positive correlation with the duration of treatment. Respondents who had repeated experiences with discontinuation of medication without a prior consultation with a psychiatrist had significantly worse attitudes towards medication than respondents without this experience. This study revealed evidence of a strong relationship between the attitudes toward medication and a history of discontinuation of taking medication and duration of treatment. Therefore, we suggest that interventions focused preventing the internalization of stigmatizing attitudes towards mental illness should be available to people with schizophrenia spectrum disorder, especially in the early stages of the illness - irrespective of the patient's age.

Background: The combination of low-load resistance training with blood flow restriction (BFR) has recently been shown to promote muscular adaptations in various populations. To date, however, evidence is sparse on how this training regimen influences muscle mass and strength in older adults.Purpose: The purpose of this systematic review and meta-analysis was to quantitatively identify the effects of low-load BFR (LL-BFR) training on muscle mass and strength in older individuals in comparison with conventional resistance training programmes. Additionally, the effectiveness of walking with and without BFR was assessed.Methods: A PRISMA-compliant systematic review and meta-analysis was conducted. The systematic literature research was performed in the following electronic databases from inception to 1 June 2018: PubMed, Web of Science, Scopus, CINAHL, SPORTDiscus and CENTRAL. Subsequently, a random-effects meta-analysis with inverse variance weighting was conducted.Results: A total of 2658 articles were screened, and 11 studies with a total population of N = 238 were included in the meta-analysis. Our results revealed that during both low-load training and walking, the addition of BFR elicits significantly greater improvements in muscular strength with pooled effect sizes (ES) of 2.16 (95% CI 1.61 to 2.70) and 3.09 (95% CI 2.04 to 4.14), respectively. Muscle mass was also increased when comparing walking with and without BFR [ES 1.82 (95% CI 1.32 to 2.32)]. In comparison with high-load training, LL-BFR promotes similar muscle hypertrophy [ES 0.21 (95% CI − 0.14 to 0.56)] but lower strength gains [ES − 0.42 (95% CI − 0.70 to − 0.14)].Conclusion: This systematic review and meta-analysis reveals that LL-BFR and walking with BFR is an effective interventional approach to stimulate muscle hypertrophy and strength gains in older populations. As BFR literature is still scarce with regard to potential moderator variables (e.g. sex, cuff pressure or training volume/frequency), further research is needed for strengthening the evidence for an effective application of LL-BFR training in older people.

We study the circuit evaluation problem (also known as the compressed word problem) for finitely generated linear groups. The best upper bound for this problem is coRP (the complements of problems in randomized polynomial time), which is shown by a reduction to polynomial identity testing for arithmetic circuits. Conversely, the compressed word problem for the linear group SL3(Z) is equivalent to polynomial identity testing. In the paper, we show that the compressed word problem for every finitely generated nilpotent group is in DET ⊆ NC2.Within the larger class of polycyclic groups we find examples where the compressed word problem is at least as hard as polynomial identity testing for skew arithmetic circuits. It is a major open problem, whether polynomial identity testing for skew arithmetic circuits can be solved in polynomial time. [ABSTRACT FROM AUTHOR]

Ultra-endurance exercise, such as an Ironman triathlon, induces muscle damage and a systemic inflammatory response. As the resolution of recovery in these parameters is poorly documented, we investigated indices of muscle damage and systemic inflammation in response to an Ironman triathlon and monitored these parameters 19 days into recovery. Blood was sampled from 42 well-trained male triathletes 2 days before, immediately after, and 1, 5 and 19 days after an Ironman triathlon. Blood samples were analyzed for hematological profile, and plasma values of myeloperoxidase (MPO), polymorphonuclear (PMN) elastase, cortisol, testosterone, creatine kinase (CK) activity, myoglobin, interleukin (IL)-6, IL-10 and high-sensitive C-reactive protein (hs-CRP). Immediately post-race there were significant (P < 0.001) increases in total leukocyte counts, MPO, PMN elastase, cortisol, CK activity, myoglobin, IL-6, IL-10 and hs-CRP, while testosterone significantly (P < 0.001) decreased compared to prerace. With the exception of cortisol, which decreased below prerace values (P < 0.001), these alterations persisted 1 day post-race (P < 0.001; P < 0.01 for IL-10). Five days post-race CK activity, myoglobin, IL-6 and hs-CRP had decreased, but were still significantly (P < 0.001) elevated. Nineteen days post-race most parameters had returned to prerace values, except for MPO and PMN elastase, which had both significantly (P < 0.001) decreased below prerace concentrations, and myoglobin and hs-CRP, which were slightly, but significantly higher than prerace. Furthermore, significant relationships between leukocyte dynamics, cortisol, markers of muscle damage, cytokines and hs-CRP after the Ironman triathlon were noted. This study indicates that the pronounced initial systemic inflammatory response induced by an Ironman triathlon declines rapidly. However, a low-grade systemic inflammation persisted until at least 5 days post-race, possibly reflecting incomplete muscle recovery. [ABSTRACT FROM AUTHOR]

- Abstract
In this study the flow field and the acoustic field over a high-lift configuration consisting of a deployed slat and a main wing is numerically analyzed. The flow parameters are Ma = 0.16, Re = 1.4 * 106, αSlat = 23° and αgeo = 13°. The flow data, which are computed via a large-eddy simulation, provide the distributions being plugged in the source terms of, e.g. the acoustic perturbation equations (APE) or the Ffowcs-Williams and Hawkings (FWH) equation, to compute the acoustic near field. The analysis shows the interaction of the shear layer of the slat trailing edge and the slat gap flow to generate higher vorticity than the main airfoil trailing edge shear layer. Thus, the slat gap is the dominant noise region. [ABSTRACT FROM AUTHOR]

Introduction: Over the past decade, collagen peptide (CP) supplements have received considerable attention in sports nutrition research. These supplements have shown promising results in improving personal health, enhancing athletic performance, and preventing injuries in some but not all studies.A systematic review and meta-analysis of randomized controlled trials (RCTs) has been conducted to investigate the effects of long-term daily collagen peptide (CP) supplementation on strength, musculotendinous adaptation, functional recovery, and body composition in healthy adults, both with and without concurrent exercise interventions over several weeks.The PRISMA with PERSiST guidelines were followed for this systematic literature review, which was conducted in December 2023 using PubMed, Scopus, CINAHL, and SPORTDiscus databases. Eligible studies included healthy, normal to overweight adults over 17 years of age who engaged in exercise and daily collagen peptide (CP) supplementation for a minimum of 8 weeks (except one 3-week trial only included for maximal strength). Studies examining recovery-related outcomes were also eligible if they included a 1-week supplementation period without exercise. Methodological study quality was assessed using the PEDro scale. A random-effects model with standardized mean differences (SMD) of change scores was chosen to calculate overall effect sizes.Nineteen studies comprising 768 participants were included in both the systematic review and meta-analysis. Results indicate statistically significant effects in favor of long-term CP intake regarding fat-free mass (FFM) (SMD 0.48,
p < 0.01), tendon morphology (SMD 0.67,p < 0.01), muscle architecture (SMD 0.39,p < 0.01), maximal strength (SMD 0.19,p < 0.01), and 48 h recovery in reactive strength following exercise-induced muscle damage (SMD 0.43,p = 0.045). The GRADE approach revealed a moderate certainty of evidence for body composition, a very low certainty for tendon morphology and mechanical properties, and a low certainty for the remaining.This systematic review and meta-analysis represents the first comprehensive investigation into the effects of long-term CP supplementation combined with regular physical training on various aspects of musculoskeletal health in adults. The findings indicate significant, though of low to moderate certainty, evidence of improvements in fat-free mass (FFM), tendon morphology, muscle mass, maximal strength, and recovery in reactive strength following exercise-induced muscle damage. However, further research is required to fully understand the mechanisms underlying these effects, particularly regarding tendon mechanical properties and short-term adaptations to collagen peptide (CP) intake without exercise, as observed in recovery outcomes. Overall, CP supplementation appears promising as a beneficial adjunct to physical training for enhancing musculoskeletal performance in adults.Open Science Framework (Registration DOI: https://doi.org/10.17605/OSF.IO/WCF4Y).Objective: Over the past decade, collagen peptide (CP) supplements have received considerable attention in sports nutrition research.
