Selected morphological, cardiovascular and neuromuscular risk profiles among asymptomatic sedentary men performing Islamic prayer

Abstract

Background: This study investigated morphological, cardiovascular and neuromuscular profiles among asymptomatic sedentary men performing the Islamic prayer (Salaah). This study emphasised the need for an inquiry into unique sedentary populations who perform Islamic prayer as physical activity.

Methods: An experimental study was conducted among male participants (n=20). Resting heart rate (RHR), resting systolic blood pressure (SBP), resting diastolic blood pressure (DBP), body mass index (BMI) and percentage body fat (BF%) were measured before a timed Salaah simulation activity. Electromyography (EMG) of the vastus medialis oblique (VMO) was measured for maximum voluntary contraction (MVC) and two movement transitions of the Islamic prayer (Salaah). Bilateral manual muscle strength (MMT) testing was also completed. Inferential and descriptive statistical analyses were performed using SPSS (IBM, V.27.0). Pearson's correlation coefficient was used to determine statistically significant relationships between variables. The level of significance was set at p<0.05.

Results: Negative correlations between post-Salaah SBP and MVC average (r=-0.19; p=0.42) and between the post-Salaah DBP and the MVC average (r=-0.40; p=0.08) were not significant. Weak correlations were found between the MVC average and the right (r=0.14; p=0.56) and left (r=0.18; p=0.44) quadriceps femoris MMT values.

Conclusions: This study demonstrated that individuals who performed the Salaah were reasonably healthy in terms of BMI, BF%, RHR, resting SBP, resting DBP, MMT and MVC average values. The study further demonstrated the electromyographic activity of the VMO muscle through the Salaah for two movement transitions of the prayer. Verily, this demonstrates preliminary evidence of EMG activity for the VMO muscle in those who perform the Salaah.
