Supplementation with Silk Amino Acids improves physiological parameters defining stamina in elite fin-swimmers

BACKGROUND Previous animal study has shown that supplementation with silk amino acid hydrolysate (SAA) increases stamina in mice. The presented study was the first formal evaluation of the influence of SAA supplementation on parameters defining physiological fitness level in humans. METHODS It was a randomized controlled trial with a parallel-group design on elite male fin-swimmers. The exper...

Silk amino acids improve physical stamina and male reproductive function of mice.

The effects of a silk amino acid (SAA) preparation on the physical stamina and male reproductive function of mice were investigated. Eight-week-old male ICR mice (29-31 g) were orally administered SAA (50, 160 or 500 mg/kg) for 44 d during 30-min daily swimming exercise. The mice were subjected to a weight-loaded (5% of body weight) forced swimming on the 14th, 28th and 42nd day to determine ma...

Shoulder Pain in Elite Swimmers

Much research has investigated shoulder pain which inhibits the performance of elite swimmers. An ever increasing understanding of the epidemiology and aetiology of what has been termed 'swimmer's shoulder' has enabled better treatment, rehabilitation and prevention programs to be implemented. This paper reviews the current research relevant to 'swimmer's shoulder' and the methods of treatment ...

Changes in physiological and stroke parameters during a maximal 400-m free swimming test in elite swimmers.

The aim of this study was to analyse the variations of the metabolic and technical parameters during a maximal 400-m freestyle event. Seven trained male swimmers swam a maximal 400-m freestyle as if in competition (255.8 +/- 6.9 s). Intermediate time and stroke rate (SR) were recorded at each length (25 m). To estimate the changes in metabolic parameters during the 400-m event, they swam a 300-...
