Spirulina platensis prevents oxidative stress and inflammation promoted by strength training in rats: dose-response relation study.

The purpose of this study was to evaluate the effects of Spirulina Platensis supplementation on selected blood markers of oxidative stress, muscle damage, inflammation, and performance in trained rats. Rats (250 g - 300 g) were submitted to a strength training program (eight weeks), divided into four groups: control (GT) (trained without supplementation), trained with daily-supplementation of 50 mg/kg (GT50), 150 mg/kg (GT150) and 500 mg/kg (GT500). Training consisted of a jump protocol in PVC-cylinder containing water, with increasing load over experimental weeks.

Supplementation with Modulates Aortic Vascular Reactivity through Nitric Oxide and Antioxidant Activity.

The possible mechanism is involved in the effects of on vascular reactivity. Animals were divided into sedentary group (SG) and sedentary groups supplemented with at doses of 50 (SG50), 150 (SG150), and 500 mg/kg (SG500). To evaluate reactivity, cumulative concentration-response curves were constructed for phenylephrine and acetylcholine.

Aortic Response to Strength Training and Dependent on Nitric Oxide and Antioxidants.

Studies have shown that supplementation with improves vascular reactivity. However, it is unclear whether in association with strength training this effect can be enhanced. Thus, this study aimed to determine the effects of strength training and on the reactivity of the aorta from Wistar rat and the possible mechanisms involved.

Carbohydrate supplementation attenuates decrement in performance in overtrained rats.

Carbohydrate ingestion at the end of a single exercise is recognized as delaying fatigue and accelerating recovery, but whether chronic ingestion can prevent overtraining during periods of intense training has not yet been elucidated. This study aimed to determine whether carbohydrate supplementation minimizes overtraining in Wistar rats. The animals underwent 11 weeks of training (running) on a treadmill, and the last 3 weeks were designed to induce overtraining.
