“…An increase in glucose transporter type 4 (GLUT4) expression is suggested when Cr supplementation is combined with exercise [ 29 ]; positive effects of Cr supplementation are seen at initial levels and also by maintaining high levels of muscle glycogen for up to 2 h [ 30 ]. In addition, training tends to promote central and peripheral fatigue, along with other endocrine, immunological, inflammatory, and oxidative stress [ 31 ]. Moreover, training tends to modulate physiological adaptation and improve physical performance indicators [ 32 ].…”

The aim of the present study was to analyze the effect of creatine (Cr) supplementation on peak torque (PT) and fatigue rate in Paralympic weightlifting athletes. Eight Paralympic powerlifting athletes participated in the study, with 25.40 ± 3.30 years and 70.30 ± 12.15 kg. The measurements of muscle strength, fatigue index (FI), peak torque (PT), force (kgf), force (N), rate of force development (RFD), and time to maximum isometric force (time) were determined by a Musclelab load cell. The study was performed in a single-blind manner, with subjects conducting the experiments first with placebo supplementation and then, following a 7-day washout period, beginning the same protocol with creatine supplementation for 7 days. This sequence was chosen because of the lengthy washout of creatine. Regarding the comparison between conditions, Cr supplementation did not show effects on the variables of muscle force, peak torque, RFD, and time to maximum isometric force (p > 0.05). However, when comparing the results of the moments with the use of Cr and placebo, a difference was observed for the FI after seven days (U3: 1.12; 95% CI: (0.03, 2.27); p = 0.02); therefore, the FI was higher for placebo. Creatine supplementation has a positive effect on the performance of Paralympic powerlifting athletes, reducing fatigue index, and keeping the force levels as well as PT.

“…It is well known that high intensity exercise causes an increase in reactive oxygen species (ROS), altering the redox balance and increasing oxidative stress [ 1 , 2 ]. This increase in ROS can cause damage to the cell membrane and dysfunctions in the cellular mitochondria [ 3 ], which are associated with increased fatigue and loss of performance [ 4 , 5 ].…”

Hydrogen-rich water (HRW) is used as a supplement to improve performance and reduce fatigue in athletes. However, the potentially beneficial effects of HRW intake could be mediated by the training status of athletes. The purpose of the study was to analyse the ergogenic effect of intake of HRW for one week on aerobic and anaerobic performance, both in trained and untrained individuals. Thirty-seven volunteers participated in the study and were divided into two experimental groups: trained cyclists and untrained subjects. A double-blind crossover design was performed in which all subjects took a placebo (PW) and nano-bubble HRW (pH: 7.5; hydrogen concentration: 1.9 ppm; oxidation-reduction potential (ORP): -600 mV). At the end of 7-day intake, performance was assessed by an incremental VO 2 max test and by a maximum anaerobic test. After HRW intake, only trained cyclists improved their performance in the anaerobic test with an increase in peak power (from 766.2 ± 125.6 to 826.5 ± 143.4 W; d = .51) and mean power (from 350.0 ± 53.5 to 380.2 ± 71.3 W; d = .51), and a decrease in the fatigue index (from 77.6 ± 5.8 to 75.1 ± 5.9%; d = .45). The findings demonstrate that the ergogenic effect of HRW is mediated by the training status, and that 7-day intake of HRW would be an effective strategy for improving anaerobic performance in trained cyclists.

OBJETIVO: determinar el efecto de una prueba aeróbica de natación en piscina clorada indoor sobre la concentración de NO2-, H2O2 y el pH en el condensado del aire espirado. MÉTODO: diez nadadores aficionados nadaron 2,5 km en piscina clorada. Se obtuvieron muestras antes y en cuatro oportunidades durante las ocho horas posteriores a la prueba. El análisis estadístico usó modelos mixtos y la prueba de Spearman RESULTADOS: la prueba se realizó a 74,99±10,10 % de la reserva cardíaca y duró 50,80±8,98 minutos. Posterior a la prueba disminuyó el NO2- (p=0,04) y el pH (p=0,02) en el condensado del aire espirado. Los valores pre-ejercicio se relacionaron con los cambios absolutos p=0,0002, p=0,047 y con el volumen de entrenamiento p=0,017, p=0,077 para NO2- y H2O2 respectivamente. CONCLUSIONES: la natación en piscina clorada disminuye la concentración de NO2- y el pH en el condensado del aire espirado.
