25(OH)D3 Levels Relative to Muscle Strength and Maximum Oxygen Uptake in Athletes

between 25(OH)D 3 levels and muscle strength in professional athletes, particularly high-rank professional athletes. It should also be pointed out that low serum 25-hydroxycholecalciferol (25(OH)D 3 ) levels can contribute to myocardial hypertrophy, increased blood pressure, endothelial dysfunction and decreased maximum oxygen uptake (VO 2max ). While the available literature abounds in data on the relationship between Vitamin D levels and cardiorespiratory fitness in subjects with a low level of physical activity ( Turkbey et al., 2010 ), reports on similar studies

Muscle Strength and Speed Performance in Youth Soccer Players

Introduction Performance in a soccer match depends on a variety of factors such as skills, tactics, and players’ physiological, physical and mental capacities ( Stolen et al., 2005 ). Small changes in these capacities can have significant effects on the development and result of a match and/or a championship ( Chelly et al., 2009 ; Comfort et al., 2012 ; Stolen et al., 2005 ). In soccer, numerous attempts have been made to determine whether adult players’ muscle strength is related to their speed. Although sprint actions only constitute 11% of the total

Spruce Needle Polyprenols Protect Against Atorvastatin-Induced Muscle Weakness and do not Influence Central Nervous System Functions in Rats

Abstract

Polyprenols (PPs) have been identified in almost all living organisms. The richest source of PPs is the needles of conifer trees. Endogenously, PPs, similarly to cholesterol, are synthesised in human and animal cells via the mevalonate pathway. Previous studies have demonstrated the anti-oxidant properties of PPs. To our knowledge, no studies have been published on the influence of PPs on muscle strength. We hypothesised that administration of PPs could prevent changes in muscle functioning caused by statins (weakness, etc.). In the present study, atorvastatin (80 mg/kg) was used as a model compound. PPs at doses 1, 10 and 20 mg/kg were administered. Both drugs were given per os for 16 days. The influence of atorvastatin, PPs and their combination on behaviour, muscle strength, plasma cholesterol and creatine kinase activity was assessed in female Wistar rats. Our data demonstrated that atorvastatin considerably impaired muscle strength, whereas PPs protected that effect. Neither PPs, nor atorvastatin influenced plasma cholesterol levels, whereas PPs at dose 20 mg/kg elevated creatine kinase activity by about 25%. PPs at the tested doses did not alter behaviour, indicating safety of central nervous system functions. The obtained data suggest usefulness of PPs as a complement in statin therapy to reduce muscle-related side effects.
