Core muscular network is important for function. An experimental study was conducted in 120 healthy individuals in the age group of 20 to 30 years. They were randomly assigned into 3 groups of 40 each – control, rhythmic stabilization training and combination of isotonic exercises. Core muscle strength was measured using core stability gradation and endurance with lumbopelvic stability test. There was statistically significant difference observed in post values of core muscle strength (p = 0.000) and endurance (p = 0.000) in all the three groups using one-way ANOVA test. Combination of isotonic exercises is better than Rhythmic stabilization and control group. Hence, proprioceptive neuromuscular facilitation techniques have a significant effect on core strength and endurance in healthy individuals.
