Ramadan intermittent fasting induced poorer training practices during the COVID-19 lockdown: A global cross-sectional study with 5529 athletes from 110 countries حسب Washif, Jad

"…Ramadan intermittent fasting during the COVID-19 lockdown (RIFL) may present unique demands. We investigated training practices (i.e., training load and training times) of athletes, using pre-defined survey criteria/questions, during the ‘first’ COVID-19 lockdown, comparing RIFL to lockdown-alone (LD) in Muslim athletes. …"

Hot and Hypoxic environments inhibit simulated soccer performance and exacerbate performance decrements when combined حسب Aldous, Jeffrey

"…Twelve male University soccer players completed three familiarization sessions and four randomized crossover experimental trials of the intermittent Soccer Performance Test (iSPT)in normoxic- temperate(CON:18◦C50%rH),HOT(30◦C;50%rH),HYP(1000m;18◦C50%rH),and HH(1000m;30◦C;50%rH).Physical performance and its performance decrements, bodytemperatures(rectal,skin,and estimated muscle temperature), heartrate(HR), arterial blood oxygen saturation(SaO2), perceived exertion, thermal sensation(TS), body mass changes, blood lactate, and plasma volume were all measured. …"

Ni-P-TiO2 Composite coatings on copper produced by sol-enhanced electroplating حسب Wang, Yuxin

"…Ni-P-TiO2 composite coatings were prepared on copper substrate by TiO2 sol-enhanced electroplating. A systematic study of Ni-P-X coatings with different sol concentrations (TiO2 concentration X from 0 to 50 mL/L) has been conducted in order to understand the effect of TiO2 sol addition and the strengthening mechanism. …"

Epibenthic communities from offshore platforms in the Arabian Gulf are structured by platform age and depth حسب Felipe, Torquato

"…Oil and gas platforms act as artificial habitats for a myriad of marine organisms. In this study, we used opportunistic remotely operated vehicle (ROV) data to describe fouling assemblages through the characterization of functional groups in the Al Shaheen oil field, situated in Qatari waters. …"
