Objectives: The respiratory function is often overlooked in people with Low Back Pain (LBP),
while it is one of the factors for the continuation and recurrence of lumbar spine injury. Aim
of this study was survay the immediate effect of Respiratory Muscle Sprint-Interval Training
(RMSIT) on the plantar pressure variables of athletes with LBP.
Methods: This randomized controlled trial was conducted on two groups with LBP, one
experimental group (24 patients) and one control group (23 patients). The plantar pressure
variables were recorded using a plantar pressure measurement device. The experimental
group performed the RMSIT protocol. The RMSIT was fulfilled as six sets of 30-second
deep breathing exercises (with two minutes of rest between sets) with constant tidal volume,
maximum breathing rate, and added resistance. The paired t-test and one-way covariance tests
were used to analyze the data.
Results: The results of (95%) confidence ellipse showed that RMSIT caused a significant
decrease in the amount area of sway, but the exercise did not make a significant difference
in the length of minor axis and length of the major axis. The results of the Center of Presure
(COP) factors showed that the training program significantly reduced the amount of path
length, the standard deviation in the Y axis, but the results did not show a significant difference
in the velocity and standard deviation in the X axis in the experimental group. The results
demonstrated no significant difference between the experimental and control group in the
plantar pressure symmetry indices.
Discussion: It can be concluded that, these exercises can be used to reduce some postural
oscillation indices in athletes with LBP.

Therefore, the pres-ent study was conducted to evaluate the immediate effect of Respiratory Muscle Sprint-Interval Training (RMSIT) on plantar pressure variables of athletes with chronic LBP when implementing overhead squat.
According to the paired t-test results (Table 4) in the experimental and control groups, there was no signifi-cant difference in the plantar pressure symmetry be-tween pre-test and post-test.
4. Discussion The results of this study showed that respiratory mus-cle training changed some the plantar pressure variables in athletes with LBP.
