Abstract:
The aim of the study was to grade scale selected aerobic fitness (Physiological) variables of high altitude male youth of Kashmir. The study was conducted on two hundred forty two healthy male youth of Kashmir (attitude: 6070 feet/1850 meters). The age of the subjects ranged from 18 to 23 years. The physical variables of the subjects like age, body weight and height were noted down. For selected physiological variables youth were administered submaximal bench step test (American College of Sports Medicine Protocol) for six minutes. To determine the VO2 max., plotting HR-workload combinations calculated by Karvonen heart rate reserve method was adopted. Data was collected using Cardio-Sport heart rate monitor and step test protocol. The selected variables were Resting Heart Rate = RHrest, Target Heart Rate = THR, Maximal Heart Rate = HRmax., Heart Rate at Two minutes of step testing with cadence 15 steps/min = ExHR2min, Heart Rate at Four minutes of step testing with cadence 20 steps/min = ExHR4min, Heart Rate at Six minutes of step testing with cadence 30 steps/min = ExHR6min, recovery heart rate at one minutes of rest = RcvyHR1min, recovery heart rate at two minutes of rest = RcvyHR2min, recovery heart rate at third minute of rest = RcvyHR3min and VO2 max.(As per the formula advocated by American College of Sports Medicine). The collected data was computed with mean, standard deviation, six sigma scale and chi square using SPSS. The study concluded that the developed grade scales of selected physiological variables are good normative in reference to Kashmir youth in regard to their Aerobic fitness evaluation.
