Abstract:
The purpose of this study was to study the physical fitness of Thai hill tribe youth in changwat Chiang Mai. Subjects were 300 males and females Thai hill tribe youth, ages ranged from 10 24 years old, in changwat Chiang Mai and then were divided into 5 groups in which each age group consisted of 30 males and 30 females. Body weight, height, body mass index, pulse rate at rest, blood pressure, leg strength, lung capacity, flexibility and maximal oxygen uptake were measured in each subject. The data were then analyzed in term of means and standard deviation. The results were described as follow : 1. Male Thai hill tribe youth with age group between 10 12 years, 13 15 years, 16 18 years, 19 21 years, 22 24 years had the means of body weight as 27.77, 45.04, 52.19, 55.48, 58.52 kg., respectively.

The means of pulse rate at rest were 77.13, 73.13, 70.80, 68.87, 69.77 bpm., respectively. The means of blood pressure were 106.83/68.13, 112.13/68.67, 115.03/74.80, 117.77/75.53, 114.57/73.53 mm.Hg, respectively. The means of leg strength were 2.65, 2.88, 3.18, 2.96, 2.91 kg./kg. weight, respectively. The means of lung capacity were 53.36, 50.71, 54.76, 54.86, 53.92 ml./kg., respectively. The means of flexibility were 8.37, 9.37, 9.30, 7.42, 7.47 cm., respectively, and the means of maximal oxygen uptake were 72.85, 69.20, 68.31, 66.62, 64.89 ml. / kg. / min., respectively. 2. Female Thai hill tribe youth between 10 12 years, 13 15 years, 16 18 years, 19 21 years, 22 24 years had the means of body weight as 32.32, 43.62, 45.50, 46.58, 48.63 kg., respectively. The means of height were 133.89, 144.58, 148.81, 149.93, 150.34 cm., respectively. The means of body mass index were 17.83, 20.67, 20.57, 20.73, 21.52 kg./m2, respectively. The means of pulse rate at rest were 78.43, 75.83, 73.53, 71.77, 71.10 bpm., respectively. The means of blood pressure were 105.30/66.20, 112.90/71.13, 113.37/72.83, 115.10/73.97, 114.67/74.60 mm.Hg, respectively. The means of leg strength were 1.93, 2.46, 2.51, 2.67, 2.53 kg./kg., respectively. The means of lung capacity were 45.27, 40.29, 40.98, 42.48, 38.72 ml./kg., respectively. The means of flexibility were 7.07, 8.47, 6.13, 5.95, 4.40 cm., respectively, and the means of maximal oxygen uptake were 65.92, 64.96, 62.64, 59.13, 60.34 ml./kg./min., respectively.
