Summary

Carnosine (made by bonding β-alanine and histidine) has been suggested to contribute to the extension of physical exercise, counteracting the decline in muscle performance due to fatigue. However this process is largely restricted by the levels of β-alanine available in the human body. Carnosine levels can be raised through long term ingestion of food products, such as meat, fish and poultry, however it can also be significantly increased by β-alanine supplementation. Improved β-alanine levels can potentially advance exercise capacity and exercise performance, which may have been previously limited. Recently research has demonstrated no beneficial effect of β-alanine supplementation on neuromuscular performance in active, healthy males when they were well rested, with no prior exercise or fatigue of the assessed muscle. It remains unknown if β-alanine supplementation would aid physical performance when the muscle has already been fatigued. This is currently being investigated in older adults (60-80 years), however there is no clear comparison between the potential effects in younger and older participants.

Therefore this investigation hopes to examine the effects of 4 week β-alanine supplementation on lower limb contractile and force properties, pre and post muscle specific fatigue in 18-30 year old males.
