Acute effects of running and blood flow restriction on gas exchange and perceptual responses. J Strength Cond Res 39(3): e436–e443, 2025—The purpose of this investigation was to examine gas exchange and perceptual responses during discrete running bouts performed at different peak running speeds with and without blood flow restriction (BFR). Twelve college-aged male subjects randomly performed four, 3-minute running bouts at 70%BFR, 80%BFR, and 90%BFR of their running speed at peak V̇o2 with BFR (applied bilaterally and most proximally on each leg) at 40% of total arterial occlusion pressure and 100%NOBFR of their running speed at peak V̇o2 without BFR. Separate 2-way, 4 (Speed [70%BFR, 80%BFR, 90%BFR, and 100%NOBFR]) × 3 (Time [120, 150, and 180 seconds]), Bayesian repeated-measure models were performed to examine differences in oxygen consumption (V̇o2), carbon dioxide production (V̇co2), and minute ventilation (V̇E) as well as ratings of perceived exertion (RPE) and pain. V̇o2, V̇co2, and V̇E increased across running speeds and was similar between the 90%BFR and 100%NOBFR speeds for V̇o2 (Meandiff = −1.49 ± 0.003 ml·kg−1·min−1; 95% HDI: −4.8 to 1.8) and V̇E (Meandiff = −6.97 ± 0.65 L·min−1; 95% HDI: −16.5 to 2.52). Ratings of perceived exertion was highest during the 90%BFR and 100%NOBFR speeds (90%BFR and 100%NOBFR \u003e 80%BFR \u003e 70%BFR), whereas pain was greater during the 90%BFR speed relative to the 70%BFR (Meandiff = −1.31 ± −0.20 au; 95% HDI: −2.63 to −0.0165) and 100%NOBFR (Meandiff = 1.3 ± 0.26 au; 95% HDI: 0.01–2.56) speeds. Applying BFR during 90%BFR of peak running speed induced comparable V̇o2 and V̇E responses as 100%NOBFR but was not associated with lower RPE and provoked more pain. Collectively, BFR exhibits a small, potentially negligible effect on gas exchange, which were largely speed dependent. Coaches and practitioners may consider treadmill running with BFR when reductions in exercise intensity are warranted.","source":"Semantic Scholar","year":2025,"language":"en","subjects":["Medicine"],"doi":"10.1519/JSC.0000000000004994","url":"https://www.semanticscholar.org/paper/2101e021c9fc6e1441b6727378e0608204bfcd62","is_open_access":true,"citations":5,"published_at":"","score":69.15},{"id":"ss_8c0a68572f79b9ec19854282bf0a12fb6b9dc014","title":"Signatures of planets and Galactic subpopulations in solar analogs.

We developed a neural network (NN) algorithm using Python to derive atmospheric parameters and chemical abundances for a sample of 99 solar twins and solar analogs previously studied in the literature from normalized high-quality spectra from HARPS, with a resolving power of R ∼ 115000 and a signal-to-noise ratio of S/N \u003e 400. We obtained precise atmospheric parameters and abundance ratios X/Fe of 20 chemical elements (Li, C, O, Na, Mg, Al, Si, S, Ca, Sc, Ti, V, Cr, Mn, Co, Ni, Cu, Zn, Y, and Ba). The results we obtained are in line with the literature, with average differences and standard deviations of $(2 ± 27)$ K for T_ eff, $(0.00 ± 0.06)$ dex for log g, $(0.00 ± 0.02)$ dex for Fe/H $(-0.01 ± 0.05)$ km s^-1 for microturbulence velocity (v_t), $(0.02 ± 0.08)$ km s^-1 for the macro turbulence velocity (vmacro), and $(-0.12 ± 0.26)$ km s^-1 for the projected rotational velocity (vsini). Regarding the chemical abundances, most of the elements agree with the literature within 0.01 - 0.02 dex. The abundances were corrected from the effects of the Galactic chemical evolution through a fitting versus the age of the stars and analyzed with the condensation temperature (T_ cond) to verify whether the stars presented depletion of refractories compared to volatiles. We found that the Sun is more depleted in refractory elements compared to volatiles than 89% of the studied solar analogs, with a significance of 9.5σ when compared to the stars without detected exoplanets. We also found the possible presence of three subpopulations in the solar analogs: one Cu-rich, one Cu-poor, and the last one being slightly older and poor in Na.","source":"Semantic Scholar","year":2025,"language":"en","subjects":["Physics","Computer Science"],"doi":"10.1051/0004-6361/202554675","url":"https://www.semanticscholar.org/paper/8c0a68572f79b9ec19854282bf0a12fb6b9dc014","is_open_access":true,"citations":2,"published_at":"","score":69.06},{"id":"ss_777977c61abbcfeb5b741fee97746c2d129b00f3","title":"Effects of Different Exercise Training on Physical Fitness and Technical Skills in Handball Players.

Effects of different exercise training on physical fitness and technical skills in handball players. A systematic review. J Strength Cond Res 38(11): e695–e705, 2024—This review aimed to assess the effects of exercise training on handball players' performance. A thorough search was conducted in 5 online databases (ProQuest, PubMed, Science Direct, Web of Science, and EBSCOhost (SPORTDiscus), as well as on Google Scholar and other gray literature references starting on April 11, 2022. The methodological quality of the included research was evaluated using the Physiotherapy Evidence Database scale. This systematic review includes 16 studies. Eight studies received “excellent” ratings (≥6 points), 5 received “good” ratings (5 points), and 3 received “moderate” ratings (4 points). The findings showed that the most frequently examined performance factors in exercise training intervention strategies with handball players were balance (n = 5), agility (n = 8), speed (n = 9), and jumping performance (n = 10). Muscular strength (n = 4), shooting and dribbling skill (n = 3), and muscular endurance (n = 4) were the second most frequently investigated performance factors. Regarding speed and agility, exercise training considerably improved the physical fitness of handball players. However, evidence related to muscular strength, shooting ability, and dribbling skills was limited. To achieve the optimum standard, handball players must have strong physical and physiological qualities. Meanwhile, no evidence was found related to the impacts of exercise training on power, endurance, flexibility, body composition, cardiovascular fitness, and cardiorespiratory fitness. Regarding limitations, there is a need for more research with solid evidence to determine the impacts of exercise training interventions on athletes' performance in handball.","source":"Semantic Scholar","year":2024,"language":"en","subjects":["Medicine"],"doi":"10.1519/JSC.0000000000004908","url":"https://www.semanticscholar.org/paper/777977c61abbcfeb5b741fee97746c2d129b00f3","is_open_access":true,"citations":2,"published_at":"","score":68.06},{"id":"ss_d1aea5f2416ae905aeacc241f034562faf61f019","title":"Autonomic Nervous System Indices of Player Readiness During Elite-Level Rugby Union Game-Week Microcycles","authors":[{"name":"A.

Autonomic nervous system indices of player readiness during elite-level rugby union game-week microcycles. J Strength Cond Res 36(11): 3173–3178, 2022—Elite-level rugby union (RU) is a high-intensity contact sport that involves large training and match volumes across a season, which can lead to postmatch fatigue. Autonomic nervous system (ANS) regulation and perceived fatigue have been suggested to relate to measures of training and match load in RU. However, there have been no studies to assess specific ANS variables in elite RU during in-season microcycles. Player readiness during game-week microcycles was measured via heart rate variability (HRV) indices, direct current potential and self-reported well-being among 13, elite, male RU players. To enable comparison, data collection days were categorized in relation to their proximity to match day, ranging from match day minus 3 (MD − 3), to match day plus 3 (MD + 3). Differences between match days were evaluated using general linear models and Cohen's d effect sizes. There were significant differences between MD and MD + 1 for ANS indices (RMSSD p = 0.04, d = −0.66, 95% CI 0.11–1.20; the standard deviation of NN intervals p = 0.04, d = −0.66, 95% CI 0.12–1.20; total power p = 0.05, d = −0.65, 95% CI 0.11–1.20) and wellness measures (readiness p = 0.18; d = −2.33, 95% CI, 1.54–3.13; energy p = 0.02; d = −2.24, 95% CI 1.44–3.03; soreness p = 0.00; d = −2.42, 95% CI 1.63–3.23). Match day plus 3 effects were significantly greater than MD + 1 in several ANS responses, with wellness recovering at a slower time-course than ANS responses. Measures of HRV are dysregulated postmatch, but based on their rapid recovery thereafter, using HRV to assess readiness of elite-level players in RU across a weekly microcycle could be limited and requires further investigation.","source":"Semantic Scholar","year":2022,"language":"en","subjects":["Medicine"],"doi":"10.1519/JSC.0000000000004292","url":"https://www.semanticscholar.org/paper/d1aea5f2416ae905aeacc241f034562faf61f019","pdf_url":"https://eprints.leedsbeckett.ac.uk/id/eprint/9424/1/AutonomicNervousSystemIndicesOfPlayerReadinessDuringElitelevelRugbyUnionGameweekMicrocyclesAM-SAWCZUK.pdf","is_open_access":true,"citations":6,"published_at":"","score":66.18},{"id":"ss_b2a2d1b0c05364ad31819816fe6b5cf89c7345c4","title":"Hypoxia Differentially Affects Healthy Men and Women During a Daytime Nap With a Dose-Response Relationship: a Randomized, Cross-Over Pilot Study","authors":[{"name":"A.

Objective: To evaluate the neuroendocrine response to hypoxic stress during a daytime nap and its cognitive impact. Design, Subject, and Setting: Randomized, single-blind, three period cross-over pilot study conducted with 15 healthy lowlander subjects (8 women) with a mean (SD) age of 29(6) years (Clinicaltrials identifier: NCT04146857, https://clinicaltrials.gov/ct2/show/NCT04146857?cond=napping\u0026draw=3\u0026rank=12). Interventions: Volunteers underwent a polysomnography, hematological and cognitive evaluation around a 90 min midday nap, being allocated to a randomized sequence of three conditions: normobaric normoxia (NN), normobaric hypoxia at FiO2 14.7% (NH15) and 12.5% (NH13), with a washout period of 1 week between conditions. Results: Primary outcome was the interbeat period measured by the RR interval with electrocardiogram. Compared to normobaric normoxia, RR during napping was shortened by 57 and 206 ms under NH15 and NH13 conditions, respectively (p \u003c 0.001). Sympathetic predominance was evident by heart rate variability analysis and increased epinephrine levels. Concomitantly, there were significant changes in endocrine parameters such as erythropoietin (∼6 UI/L) and cortisol (∼100 nmol/L) (NH13 vs. NN, p \u003c 0.001). Cognitive evaluation revealed changes in the color-word Stroop test. Additionally, although sleep efficiency was preserved, polysomnography showed lesser deep sleep and REM sleep, and periodic breathing, predominantly in men. Conclusion: Although napping in simulated altitude does not appear to significantly affect cognitive performance, sex-dependent changes in cardiac autonomic modulation and respiratory pattern should be considered before napping is prescribed as a countermeasure.","source":"Semantic Scholar","year":2022,"language":"en","subjects":["Medicine"],"doi":"10.3389/fphys.2022.899636","url":"https://www.semanticscholar.org/paper/b2a2d1b0c05364ad31819816fe6b5cf89c7345c4","pdf_url":"https://www.frontiersin.org/articles/10.3389/fphys.2022.899636/pdf","is_open_access":true,"citations":6,"published_at":"","score":66.18},{"id":"crossref_10.5937/zasmat2102095a","title":"Mechanisms and morphologies of cavitation damage of NN 70 steel","authors":[{"name":"Vujadin Aleksić"},{"name":"Ljubica Milović"},{"name":"Ana Maksimović"}],"abstract":"Broken test tubes for low-cycle fatigue testing of Nionicral 70 (NN-70) parent material (PM) steel and simulated heat-affected zones (SHAZ) were used to produce samples for cavitation resistance testing.

In particular, we compute both the $\\mathcal{O}(1)$ corrections quantifying fluctuations from typicality in the ensemble of networks, and the subleading $\\mathcal{O}(T/N)$ corrections due to finite-width effects. These provide corrections to the correlation length that controls the depth to which information can propagate through the network, and thereby sets the scale at which such networks are trainable by gradient descent.

Conventional MPPT algorithms (e.g., perturb and observe (P\u0026O), hill climbing, and incremental conductance (Inc-Cond) etc.) are trial-and-error-based, which may result in steady-state oscillations and loss of tracking direction under fast changing ambient environment.

This study examined the potential of Multi-layer Perceptron Neural Network (MLP-NN) in predicting dissolved oxygen (DO) at Johor River Basin. The river water quality parameters were monitored regularly each month at four different stations by the Department of Environment (DOE) over a period of ten years, i.e. from 1998 to 2007. The following five water quality parameters were selected for the proposed MLP-NN modelling, namely; temperature (Temp), water pH, electrical conductivity (COND), nitrate (NO3) and ammonical nitrogen (NH3-NL). In this study, two scenarios were introduced; the first scenario (Scenario 1) was to establish the prediction model for DO at each station based on five input parameters, while the second scenario (Scenario 2) was to establish the prediction model for DO based on the five input parameters and DO predicted at previous station (upstream). The model needs to verify when output results and the observed values are close enough to satisfy the verification criteria. Therefore, in order to investigate the efficiency of the proposed model, the verification of MLP-NN based on collection of field data within duration 2009–2010 is presented. To evaluate the effect of input parameters on the model, the sensitivity analysis was adopted. It was found that the most effective inputs were oxygen-containing (NO3) and oxygen demand (NH3-NL). On the other hand, Temp and pH were found to be the least effective parameters, whereas COND contributed the lowest to the proposed model. In addition, 17 neurons were selected as the best number of neurons in the hidden layer for the MLP-NN architecture. To evaluate the performance of the proposed model, three statistical indexes were used, namely; Coefficient of Efficiency (CE), Mean Square Error (MSE) and Coefficient of Correlation (CC). A relatively low correlation between the observed and predicted values in the testing data set was obtained in Scenario 1. In contrast, high coefficients of correlation were obtained between the observed and predicted values for the test sets of 0.98, 0.96 and 0.97 for all stations after adopting Scenario 2. It appeared that the results for Scenario 2 were more adequate than Scenario 1, with a significant improvement for all stations ranging from 4 % to 8 %.","source":"Semantic Scholar","year":2011,"language":"en","subjects":["Environmental Science"],"doi":"10.5194/HESS-15-2693-2011","url":"https://www.semanticscholar.org/paper/cbf44f1c9b6956312ef327ade79ee40b58f150f4","pdf_url":"https://hess.copernicus.org/articles/15/2693/2011/hess-15-2693-2011.pdf","is_open_access":true,"citations":45,"published_at":"","score":56.35},{"id":"ss_7e78ac23e6b5c1e48b50c927d3e5bc878bf410f6","title":"Integration of financial systems of western Balkan countries into the european financial system","authors":[{"name":"Artor R.
