Background: The role of diaphragmatic function is of utmost importance in the attainment of optimal respiratory performance, particularly in individuals who are obese, particularly those who are centrally obese. There have been reports of variations in diaphragm function over the course of a day, thereby leading to investigations into the potential influence of environmental factors, such as rapid cooling, on the movement and strength of the diaphragm.

Aim and Objective: This study aims  to find the effect on diaphragmatic excursion and strength following quick icing among people with   central obesity associated with diurnal variation.  To evaluate the diaphragmatic excursion after quick icing associated with diurnal variation and to evaluate the diaphragmatic strength after quick icing associated with diurnal variations.

A total of 36 participants will be selected on the basis of inclusion and exclusion criteria. Pre-assessment will be taken using three primary outcome measures. these are MED scale, MMT and EMG. Participants will be recruited from Jalandhar, Punjab and Mumbai, Maharashtra. Demographic information will be taken whereas thoroughly explained about the rules and regulations of the study. Quick icing will be applied on two different times (morning and evening). Post assessment will be taken on 4th week.
