To investigate the effects of altitude training on the development of elite kayakists` muscle strength and aerobic capacity. 28 kayakists, 15 of them from Chinese national team (6 males, 21.0±0.6yrs, 3.1±4.3kg; 9 females, 20.2±0.8yrs., 75.4±2.1kg), 13 of them (males) from a province club (8 in exp. group, 21.2±1.7yrs., 80.5±4.2kg; 5 in contr. group, 18.9±1.1yrs, 79.3±1.6kg). Training manoeuvre: The every week`s on-water exercise volume (km) of the national team members during altitude training was 90% of that on low land .The strength training volume on altitude was the same as on low land. The province club members` on-water training volume and the strength training volume during experiment were respectively 70% and 50% of that as usual. Both the exp. group and the contr. group shared the same training program. The only difference was that the exp. group trained on altitude, the contr. group trained at sea level. After 4 weeks` altitude (1843m) training, the national team members` MR-1 weight in bench-pull was significantly reduced (males: 136.0±2.7kg vs 132.6±3.5kg; p<0.05; females: 90.4±2.2kg vs. 81.2±2.7kg, p<0.01). The male members` 1min. and 2min. performances on kayaking ergometer went down ( 372.3±26.7w, 304.4±18.7w vs. 369.2±19.2w, 300.3±16.7w); the female members` did not change significantly. The female members` on water performances were down in k1 500m (115.1±5.1sec. vs 119.2±6.0sec., p<0.05), unchanged in k1 5000m (1410±111sec. Vs 1400±107sec. P>0.05). After 4 weeks` altitude training, the province club members` isokinetic strength at shoulders and knees (tested on Cybex II+) was down significantly (too many data to show), VO2max (tested on Jaeger EOS-Sprint) was reduced (5.17±0.16L/min. vs. 4.95±0.21l/min., P<0.05). 4min.working capacity on kayaking ergometer was down (247.3±7.1w vs 233.3±4.9w, p<0.05). The control group members` isokinetic strength was less reduced, and the VO2max and the working capacity on ergometer kept unchanged. Such altitude training did not show better effects on elite kayakists` muscle strength and aerobic capacity than low land training.
