Interaction Between Caffeine and Creatine When Used as Concurrent Ergogenic Supplements: A Systematic Review.

There is some controversy regarding the interactions between creatine (CRE) and caffeine (CAF) supplements. The aim of this systematic review was to study whether such ergogenic interaction occurs and to analyze the protocol to optimize their synchronous use. The PubMed, Web of Science, MEDLINE, CINAHL, and SPORTDiscus databases were searched until November 2021 following the PRISMA guidelines.

A Short-Term Resistance Training Circuit Improved Antioxidants in Sedentary Adults with Down Syndrome.

Previous studies have found aerobic training improved oxidative damage in people with Down syndrome (DS). However, there is a lack of information regarding the influence of resistance training on redox imbalance in this population. Accordingly, this study was conducted to determine the effect of resistance training (RT) on antioxidant defence system in sedentary adults with DS.

[Association between abdominal obesity and seminal oxidative damage in adults with metabolic syndrome].

Background: Abdominal obesity, metabolic syndrome (MS) and oxidative stress may impair seminal quality leading to derangements in fertility.

Aim: To identify an association between abdominal obesity and markers of seminal oxidative damage in adults with MS.

Material And Methods: Seventy males aged 25 to 40 years, with MS according to ATP-III criteria volunteered for this cross-sectional study.

A short-term arm-crank exercise program improved testosterone deficiency in adults with chronic spinal cord injury.

Purpose: To determine the influence of arm-crank exercise in reproductive hormone levels in adults with chronic SCI. Further objectives were to assess the influence of arm-crank exercise on muscle strength and body composition.

Materials And Methods: Seventeen male adults with complete SCI at or below the 5th thoracic level (T5) volunteered for this study.

Salivary testosterone and immunoglobulin A were increased by resistance training in adults with Down syndrome.

This study was designed to assess the influence of resistance training on salivary immunoglobulin A (IgA) levels and hormone profile in sedentary adults with Down syndrome (DS). A total of 40 male adults with DS were recruited for the trial through different community support groups for people with intellectual disabilities. All participants had medical approval for participation in physical activity.
