The study aimed to examine the Effects of Tabata training on key health parameters in individuals in late middle age. The researchers employed an experimental method using a one-group pretest-posttest design, suitable for the nature of the study. The sample included 22 participants (45.59 ± 4.29 years),Variables measured included Body Mass Index (BMI), Body Fat Mass (BFM), Fat-Free Mass (FFM), Skeletal Muscle Mass (SMM), Body Fat Percentage (PFM), and Skeletal Muscle Index (SMI).The results indicated statistically significant differences between the pretest and posttest means at the (α ≤ 0.05) level, favoring the posttest measurements for BMI, FFM, SMM, and SMI. However, there were no statistically significant differences for BFM and PFM, reflecting the positive impact of Tabata training on the general health of individuals in late middle age. The researchers recommend further studies on the use of Tabata training across different age groups
