Observing the impact of meal consumption on limb occlusion pressure in Indian female Collegeites
Description
ABSTRACT Background: Blood flow resistance training (BFRT), which comprises of low load, short duration, and high efficiency exercises, has recently attracted the interest of coaches, athletes, and health enthusiasts. During activity, BFRT fully blocks venous outflow while only partially enabling arterial influx into working muscles. Applying the compressible cuff to a patient, at a specific time and location requires the limb occlusion pressure (LOP) to be administered in order to restrict the blood flow in arteries, away from it. Aim and objectives: To observe the variance in LOP, before and after the consumption of meal, in Indian female collegiate and to find the correlation between LOP and other variables. Materials and method: 93 female collegiate participated in the observational study. The pre and post-meal LOP of all the participant’s lower limb was measured using handheld Doppler, cuff inflator, and occlusion cuff. Analysis of data was done using IBM Statistical Package for the Social Sciences (SPSS) software version 21. Results: A mean of 66.99 mmHg (95% CI: 57.38-84.98 mmHg) was seen before meals, with a median LOP of 260.00 mmHg (interquartile range: 230.00-300.00 mmHg). With a mean of 69.98 mmHg (95% CI: 58.91-77.74 mmHg), the median LOP dropped to 230.00 mmHg (interquartile range: 180.00-260.00 mmHg) after meals. The statistical analyses revealed a substantial decrease in LOP subsequent to meal consumption, as evidenced by the Z-score of -7.67 and p-value of 0.00 between the post-meal and pre-meal LOP. Higher weight correlated positively with pre-meal LOP levels (rho = 0.261, p = 0.011). Positive interrelation was also depicted by BMI with pre-meal LOP (rho = 0.340, p = 0.001). Conclusion: The study emphasizes how eating behaviors impact LOP in Indian women, demonstrating a consistent decrease in LOP following meals. It implies that in order to ensure proper use of BFRT procedures, LOP should be reassessed in accordance with pre or post-meal sessions, rather than BFRT being regularly administered based only on a single LOP measurement. Additionally, it shows how weight and BMI have a major impact on LOP levels before and after meals, indicating that body composition should be taken into account while studying LOP dynamics.
