本研究主要探討不同運動強度恢復期女性靜脈血漿乳酸最高值,以及
不同女性運動能力者在運動後恢復期之靜脈血漿乳酸變化情形。受試對象
為體育系女性 11名和非體育系女性 10名;平均年齡分別為20.3±1.5歲
和21.1±2.0歲;平均身高163.8±6.8公分和161.0±3.9公分;平均體
重57.0±8.2公斤和59.8±8.8公斤。每位受試者在電動跑步機上接受三次
測驗:1)漸進負荷至衰竭;2)120%VO2max至衰竭;和3) 70%VO2max運動五
分鐘;並於安靜、恢復期第3-15分鐘時抽靜脈血檢驗乳酸值。結果發現
:120%VO2max 和70%VO2max運動負荷後恢復期之乳酸最高值分別出現在第
五分鐘和第三分鐘;前者在恢復期第3-11分鐘間並無顯著差異,亦即仍維
持高值乳酸,其範圍在13-15mmol/L;至於後者,則在恢復期第3-10分鐘
間乳酸並無顯著差異存在,其濃度維持在 3-5mmol/L。也許此二時段皆是
在從事該強度運動後,恢復期測試乳酸的適當時間。體育系和非體育系受
試者在120%VO2max強度運動後,血乳酸最高值出現在恢復期第三分鐘和第
六分鐘,並顯示兩組在恢復期乳酸之適當採血時段分別在第 3-10分鐘和
第 3-14分鐘。然而70% VO2max 運動負荷後適當採血時間則分別在第3-9
分鐘和第3-14分鐘。本研究的結論是:不分運動強度或運動能力,女性於
激烈運動後恢復期自第3-10分鐘的靜脈血乳酸值均沒有顯著差異,因此都
可代表該運動強度之最高血乳酸值。
The purposes of this study were to investigate 1) the peak
venouse bloodlactate during recovery after different intensities
of exercise in females;and 2) to compare if there was a
difference in recovery peak blood lactatebetween Physical
Education (PE) and non-PE students. Eleven (11) female
PEstudents (age 20.3±1.5 yrs; height 163.8±6.8 cm; weight
57.0±8.2 kg) andten (10) female non-PE students (age 21.1±2.0
yrs; height 161.0±3.9 cm;weight 59.8±8.8 kg) were studied. All
subjects performed three treadmillrun tests which included: 1)
an icremental exercise test to exhaustion; 2) a120%VO2max
intensity exercise to exhaustion; 3) a 5min run at 70%VO2max.
Venous blood lactate levels were measured at rest and every
minute from the3rd to 15th min after completion of the 120%VO2
max and 70%VO2max intensityexercises. There was no significant
difference in lactate concentration duringthe 3rd to 11th min
post 120%VO2max exercise (13-15mmol/L, p>.05) and the
peaklactate value occurred at the 5th min of recovery. After the
70%VO2max intensityexercise, the peak lactate concentration
occurred at the 3rd min, and there wasno difference from the 3rd
to 10th min during recovery (3-5mmol/L, p>.05). Thus,from the
3rd to 10th min during recovery may be appropriate for measuring
peaklactate concentration. During the 120%VO2max recovery, the
peak lactate valuesappeared at the 3rd (15.6mmol/L) and 6th
(13.2mmol/L) minute for PE and non-PEstudents. However, the
blood lactate levels from the 3rd to the 10th min(14-16mmol/L)
for the PE group, and from the 3rd to the 14th min (11-14mmol/L)
for the non-PE group were not statistically different. For the
70%VO2maxexercise, there were no differences in lactate from the
3rd to the 9th min forPE, and from the 3rd to the 14th min for
non-PE. It can be concluded thatregardless of exercise intensity
and the subject's physical ability, the bloodsamples during the
3rd to the 10th min during recovery can all be indicative
ofexercise intensity and metabolism.
The purposes of this study were to investigate 1) the peak
