| Summary: | 碩士 === 國立體育學院 === 運動科學研究所 === 82 === This study was designed to invesgate the exercise intensity of
Waitankung (WTK). Two matched groups: middle-aged (48±7 yr)
and elderly (69±6 yr) were tested for oxygen cost, related
metabolic variables, ventilation, and heart rate during both
treadmill running and WTK performing. Physiological responses
were measured and treated by an automated respiratory gas
analyzer (Gould 2900) and ECG telemetry (Mennen). Middle-aged
group had significant higher VO2max, HRmax, and VEmax than
those of elderly group (P<0.05) during maximal exercise
testing. There were significant differences in VO2, HR, and RR
during WTK between the two matched groups (P<0.05), i.e. VO2:
10.6±1.5 vs 8.4±1.7 ml/kg/min; HR: 120.2±14.3 vs 101.3±
19.1 bpm; and RR: 23.4±4.0 vs 20.0±1.1 breaths/min. These WTK
exercise values corresponded to 30.7±4.1 ％ of VO2max and
43.2±11.5 ％ of HRR for middle-aged, 30.0±5.3 ％ of VO2max
and 30.8±11.9 ％ of HRR for elderly males. In conclusion, 1)
WTK exercise may be classed as light exercise, as it''''s
intensity dose not exceed 50 ％VO2max. 2) According responses
difference to WTK between the two matched groups, the
absolutely work load of WTK for middle-aged group seems to be
higher than that of elderly group.
