-Quantify MCARNS in veggie Vs omnivore following 5 weeks sprint training. - 5 weeks sprint training does not significantly increase MCARNS, CARNS mRNA or exercise performance in both groups following 5 weeks sprint training.

-veg group not negatively affected in performance or muscle buffering capacity.

Issues: is 5 weeks acute vegetarianism enough? Carnosine turnover rate. Dietary compliance. Study Bias, personality influenced efforts in sprint training regime. Muscle fibre distribution. Genetics. Prev sport choice, exercise intensity.

B-al deficient diet and MCARNS conc in legs. 8+years veggie, sample size 12 vs 38, suggested veg may benefit from supplement. Did not match sample size, prev. training, fibre type biopsied, genetic predisp.

matched in equal numbers, muscle fibre type considered, non sign increase type 1, Sign increase type 2a for HIIT. Following HIIT training group where shown to have signify improvements in time to exhaustion, max power output and vo2max

MCARNS increase from HIIT, independent of Bal supply. Increase MCARNS as a result of intrinsic muscle changes

-veggie diet effect on carnosine homeostasis. Exclusion criteria , measured dietary compliance via pill counting and urinary meat intake biomarkers. MCARNS unaltered by 6mnth veg. Does not depend on nutrition supply. Endog synth enough.

-no effect on time to exhaution. Questions the relationship between beta al supplement and MCARNS on exercise performance.

-24 week ba supplementation. Healthy omnivorous males. randomly / supplement and placebo. Exclusion criteria applied. Measured compliance. matched for max cycling power output, block randomisation method.

-suppl significantly increase MCARNs vs placebo. -sig improve exercise capacity , time to exhaustion . Suggest veg athletes would be greatly disadvantaged. no max MCARNS matched max exerciser performance.

Cant be sure changes in muscle buffering capacity and exercise are as a result of MCARNS increase. Lack of info on how workload max tested, is intrinsic, extrinsic motivation affecting it.

-Bal supply and MCARNS & exercise performance in healthy omniv males. -opposing findings. -MCARNS conc in all leg muscles did not sig increase following 4&6 weeks supplementation. Sign improvement found in peak power, blood and muscle ph post supp

Concluded not to be down to Bal supp, due to lack of sig found between supple & MCARNS. Concluded B-al supp may not always increase MCARNS in omniv, and in such circumstance has no effect on exercise performance, unclear relation.
