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.

Detailed description

The study will be a randomized single blinded control trial, sixty healthy smokers will be divided into two groups. a control group of 30 participants will performing a 12-minute aerobic exercise where it included walking/ jogging with a controlled speed by the participant. Another experimental group of 30 participants also, performing a 12-minute aerobic exercise where it included walking/ jogging with a controlled speed by the participant. WHBM will be performed before and after exercises. It will be done to assess the effect of WHBM on heart rate, SpO2, blood pressure and VO2 max that will be monitored before and after WHBM in the experimental group. In addition, Performance will be assessed by observing the difference in distance covered before and after doing the WHBM. Heart rate and SpO2 will be measured using a finger pulse oximeter (Medical Rossmax). Blood pressure will be measured using a sphygmomanometer and VO2 max will be measured using the cooper's test formula in kilometers: "VO2 max = (22.351 x distance in Km) - 11.288"

Interventions

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