Strong evidence during the last few decades has highlighted importance of nutrition for sport performance, role carbohydrates (CHO) being special interest. Glycogen is currently not only considered an energy substrate but also a regulator signaling pathways that regulate exercise-induced adaptations. Thus, low or high CHO availabilities can result in both beneficial negative results depending on purpose. On one hand, depletion glycogen levels limiting factor performance sessions which...

RATIONALE Isoprostanes (IsoPs) are a series of prostaglandin (PG)‐like compounds formed non‐enzymatically through free‐radical‐induced peroxidation arachidonic acid. They considered as 'gold‐standard' biomarkers for oxidative stress, in general, and lipid peroxidation, particular. METHODS A new qualitative quantitative analytical method the determination 13 eicosanoids human urine using solid‐phase extraction (SPE) ultra‐pressure liquid chromatography coupled to tandem mass spectrometry...

The aim of the present study is to analyse nutritional supplements (NS) consumption by squash players different levels (international vs. national). A total 14 international and 28 national ones answered a NS frequency questionnaire that had been previously validated. T-Student test was used for independent samples χ2 in comparative analysis among athletes levels. International level consume greater proportion (100% 67.9% p = 0.017), with differences bicarbonate soda, glutamine,...

Background: The use of sports supplements (SS) to improve performance is widespread in all types athletes, however, the specific characteristics mountain races may require certain SS. Despite being a sport where consumption SS seems widespread, few studies have been conducted this regard. objective study analyze pattern runners relation degree scientific evidence, sex, and level competition. Methods: Descriptive cross-sectional on habitual 357 federated Spain. Data were collected through...

Abstract Background Endurance athletes’ competitions have increased over the decades and marathon races are becoming increasingly popular. Proper nutrition is critical for optimal performance long-term health in athletes. This study aimed to investigate runners’ nutritional intake, especially fluids, food, supplements, competing Seville Marathon. A descriptive cross-sectional was carried out obtain information on consumption of liquids, supplements. total 160 runners (aged 42.2 ± 7.3 years)...

This study analyzes and compares sports supplement (SS) consumption among federated road cyclists, considering sex competition category. The aim is to identify key factors influencing SS use provide insights for developing nutritional strategies in cycling. A cross-sectional, descriptive was conducted, involving 1503 cyclists (1231 men 272 women). Data were collected through a validated questionnaire assessing anthropometric data, training habits, patterns, sources of information. Results...

Weightlifting is a discipline where technique and anthropometric characteristics are essential to achieve the best results in competitions. This study aims analyse relationships between body composition, limb length barbell kinematics performance of weightlifters. It consists an observational descriptive 19 athletes (12 men [28.50 ± 6.37 years old; 84.58 14.11 kg; 176.18 6.85 cm] 7 women [27.71 6.34 64.41 7.63 166.94 4.11 cm]) who met inclusion criteria. A level I anthropometrist took...

Futsal is classified as a high-intensity intermittent sport or repeated-sprint sport. Explosive and very fast movements are performed with short reaction time, interspersed playing time of 3 to 6 min during the 40 match, at intensities 85–90% maximum HR. Performance factors such agility, sprint repetition capacity, aerobic endurance lower body power, speed associated game actions. These performance can be affected by athlete’s composition. The aim determine relationship between different...

Sports supplements (SS) are widely consumed by many types of athletes to improve their performance. These SS classified according level scientific evidence, the ABCD system from Australian Institute Sport (AIS). In open water swimming, use may be necessary due physiological challenges posed this sport discipline. However, there is currently little literature on in swimmers. The aim work analyze pattern consumption swimmers, studying differences competitive (regional vs. national)....

Background: The use of sports supplements (SS) to improve performance is very common in athletes. In the case triathletes, physiological characteristics sport may require certain SS. Although consumption SS widespread this sport, few studies have investigated it thus far. aim analyze pattern by triathletes according sex and competitive level. Methodology: This a descriptive cross-sectional study on habitual 232 Spanish-federated triathletes. Data were collected through validated...

Soccer is a sport practiced all over the world and whose practice begins in young athletes. Currently, consumption of nutritional supplements essential to achieve maximum performance players. The aim this study was describe sports (CSS) by elite soccer players its association with their competitive level, playing position, sex. A comparative descriptive non-experimental performed during 2021–2022 season. total 70 completed one online questionnaire about CSS. We found that drinks (55.7%),...

The oxidized nucleoside 8-hydroxy-2'-deoxyguanosine has been widely studied as a marker of DNA oxidation; however, data on the occurrence other metabolites in plasma that are related to damage scarce. We have applied an improved, sensitive, robust, and reliable method, involving solid phase extraction ultrahigh-performance liquid chromatography (UHPLC)-tandem mass spectrometry (MS/MS), precise quantitation seven 15 elite triathletes after 2-week training program. All compounds were eluted...

People's eating habits and lifestyle can have a negative impact on health. In situations of difficulty or socioeconomic crisis, these tend to be modified, leading unhealthy dietary patterns that result in an increase chronic non-communicable diseases (NCDs). Previous studies indicated that, due the state alarm imposed Spain combat spread COVID-19, purchase non-core products occurred, along with decrease daily physical activity population. This could risk factor for COVID-19 infection. The...

CrossFit® is a high-intensity sport that combines weightlifting, gymnastic skills, and cardiovascular exercises. To find the anthropometric references define optimal body composition, it essential to first an composition for one’s physical preparation.
