CrossFit training is a high-intensity fitness training regimen that merges a variety of physical exercises, where it is designed to improve overall fitness and health, targeting multiple domains such as stamina, strength, flexibility, speed, coordination, and balance. Despite that, the existing literature on CrossFit training reveals a noticeable gap in studies specifically there are limited studies conducted comparing EMOM (Every Minute on Minute) and AMRAP (As Many Repetitions as Possible) protocols in CrossFit and lack of data examining the acute effect of CrossFit training. Thus, this study aimed to determine the acute effects of two CrossFit training protocols EMOM and AMRAP on the muscle strength of healthy adults. A quasi-experimental design was employed, with pre-test, ongoing test, and post-test assessments conducted on eight selected healthy adults. The eight participants, including 4 males and 4 females, underwent a pre-test, EMOM (2 days following the pre-test), ongoing test (2 days following the EMOM session), a washing period for 7 days, an AMRAP session, and a post-test. The upper and lower body strength test was evaluated using bench press and leg press exercises. There were no statistically significant differences found between the EMOM and AMRAP protocols in both upper and lower body strength, as p>.05. However, AMRAP demonstrated a slightly greater magnitude of improvement in muscle strength by 28.04% in upper body strength and 10.59% in lower body strength. This suggests that AMRAP may be more effective for enhancing muscle strength, but further research with larger sample sizes is warranted to confirm these findings.
