The influence of nutrition has the potential to substantially affect physical function and body metabolism. Particular attention has been focused on omega-3 polyunsaturated fatty acids (n-3 PUFAs), which can be found both in terrestrial features and in the marine world. They are responsible for numerous cellular functions, such as signaling, cell membrane fluidity, and structural maintenance. They also regulate the nervous system, blood pressure, hematic clotting, glucose tolerance, and inflammatory processes, which may be useful in all inflammatory conditions. Animal models and cell-based models show that n-3 PUFAs can influence skeletal muscle metabolism. Furthermore, recent human studies demonstrate that they can influence not only the exercise and the metabolic response of skeletal muscle, but also the functional response for a period of exercise training. In addition, their potential anti-inflammatory and antioxidant activity may provide health benefits and performance improvement especially in those who practice physical activity, due to their increased reactive oxygen production. This review highlights the importance of n-3 PUFAs in our diet, which focuses on their potential healthy effects in sport.

Adequate feeding of a horse is essential to help sustain its health and performance in different situations. Traditionally, horses are fed hay or grazed grass without or with grains plus supplements or compound feeds. However, the practice of feeding horses varies greatly in the UK depending upon the workload of a horse, co-location of the owner and the seasonal variations mainly due to the weather and the availability of pasture or hay. Although many complete feeds are also available commercially, their nutritive values do vary and thus they may not suit a horse. Therefore, there is a need to formulate nutritious diets that are palatable for a horse and cost-effective for the owner. It is also imperative to prepare diets that are more completely digested to minimise faecal contamination the environment. This study compared the suitability of three coarsely mixed diets to improve digestion and reduce excretion in adult ponies.

This review presents the principles and limitations of phosphorus nuclear magnetic resonance (31P-NMR) spectroscopy as applied to the study of striated muscle metabolism. Application of the techniques discussed include noninvasive measurement of high-energy phosphate, intracellular pH, intracellular free Mg2+, and metabolite compartmentation. In perfused cat biceps (fast-twitch) muscle, but not in soleus (slow-twitch), NMR spectra indicate a substantially lower (1 mM) free inorganic phosphate level than when measured chemically (6 mM). In addition, saturation and inversion spin-transfer methods that enable direct measurement of the unidirectional fluxes through creatine kinase are described. In perfused cat biceps muscle, results suggest that this enzyme and its substrates are in simple chemical equilibrium.
