Brief Summary

Researchers will split the sixty healthy smokers in half. Thirty people will serve as a control group and will be asked to walk or jog at a controlled pace for twelve minutes as part of an aerobic exercise program. Separately, 30 people participated in an aerobic exercise session that lasted 12 minutes and involved walking or running at a pace that the participants themselves controlled. WHBM will be done both prior to and subsequent to physical activity. To determine how WHBM affects the experimental group's pre- and post-WHBM heart rates, SpO2, blood pressure, and VO2 max, this study will be conducted.

CONTROL

ACTIVE COMPARATOR

Researchers took the first measurement at t=0 minutes after 5 minutes of their arrival to allow them to rest. The measurements included heart rate and SpO2 using an oximeter (Medical Rossmax) and blood pressure using a sphygmomanometer. Then they were asked to perform a 12-minute walk/jog with speed controlled by them and incline = 1. At 4 and 8 minutes, the speed was reduced to 2.0 on the treadmill, and vitals were taken again. At t= 12 minutes we stopped the treadmill, recorded the distance covered, and proceeded to measure the heart rate. SpO2, blood pressure, and VO2max were calculated using the Cooper's test formula (Alvero-Cruz et al., 2017). Participants were asked to rest for 4 minutes, and then another measurement of the vital signs (heart rate, SpO2, and blood pressure) was taken before they were dismissed.

Interventions

aerobic exercise where it included walking/ jogging with a controlled speed by the participant OTHER

participants were asked to listen attentively to the given instruction using noise cancelling headphones for the given instructions. For 11 minutes, an audio for Wim Hof breathing method that is as follow. * Take a strong inhalation through the nose. * Let out a relaxed exhalation through the mouth. * Repeat for 30 breaths. * On the 30th breath, exhale and hold your breath for 30 seconds in the first round then 1 minute in the 2nd round and 1 and a half minutes for the 3rd round. * Take a deep breath in after the previous hold then hold it in for 15 seconds in the 3 rounds. * Let your breathing return to normal. These steps were repeated for 3 rounds. And participants were allowed to let go of their held breath and hold it again if they couldn't keep holding it for the asked time in the audio
