Brief summary
Cardiovascular response to exercise affects the capacity of all body organs depending upon intensity, duration and mode of exercises. The aim was to compare acute effects of arm crank with treadmill moderate intensity exercises on heart rate variability in normal participants.
Detailed description
A one hundred thirty male volunteers were equally and randomly assigned to; Group-I: Sixty-five participated in an arm crank moderate intensity exercise for 40 minutes. Group-II: Sixty-five participated in a treadmill moderate intensity exercise for 40 minutes. Halter heart rate monitor and automatic sphygmomanometer were used to measure heart beat intervals and arterial blood pressure respectively.
Interventions
DEVICEArm crank
Each participant practiced on arm crank (Hudson) from long sitting position for 40 minutes. Seat's height and distance were adjusted to achieve full extension of subject arms at horizontal shoulder-level position
DEVICETreadmill
Participant practiced on an electronic computerized treadmill for 40 minutes . participant began warming up with lowest speed treadmill exercise for 5 minutes at zero inclination. Treadmill speed was increased gradually to achieve the pre-determined individualized moderate intensity for 30 minutes

Inclusion criteria
* Normal adult non-obese male subjects , their age ranges from 25-36 years. * They were asymptomatic for cardiovascular and respiratory diseases. * They currently did not receive any medical prescriptions. * All participants were asked to avoid strenuous exercise, give up caffeine and alcohol beverages to have sufficient rest for 2 days before measurement sessions to avoid any carry over effects of stimulants or depressants on autonomic functions
Exclusion criteria
* Any participant had medical history of cardiovascular and pulmonary disorders or received any interfering medications with study was excluded
