Countermovement jump
Caffeine consumption alone and combined with CitMal did not influence jump height in our study. The lack of an effect on CMJ measurements is contrary to other research on caffeine [Besides the two treatments with caffeine, isolated ingestion of CitMal did not enhance jumping performance. Rapid force production is necessary to enhance performance in the CMJ test, which is not likely to be achieved with CitMal ingestion. Indeed, CitMal ingestion is likely to be ergogenic in exercise of longer duration, whereas the performance benefit during short burst exercises is likely to be trivial or non-existential. Our results for jumping performance are similar to those from Glenn et al. [
