Anaerobic performance after 3-day consecutive CO2-rich cold-water immersion in physically active males

Effect of CO2 and H2 gas mixture in cold water immersion on recovery after eccentric loading

“…Our findings indicated that neither C-CWI with CO 2 -rich water nor regular CWI with tap water yielded favorable responses. In two earlier studies, C-CWI after aerobic exercise provided a greater recovery effect than CWI [ 17 , 37 ], whereas in the present study C-CWI did not result in any favorable responses after eccentric loading. Differences in the exercise task may thus influence the recovery effect.…”

The field study about the effects of artificial CO2-rich cool-water immersion after outdoor sports activity in a hot environment

“…In our previous studies, we investigated the effects of cold carbonated water immresion in a room controlled for room temperature and humidity. 14 , 15 , 16 In the present study, we conducted a field experiment in a real-world hot environment to test our laboratory findings in an athletic context. It has been shown that the HR decreases during water immersion due to water pressure and water temperature.…”

“… 22 Referring to the CWI data in paper Choo et al., 22 there were no differences in thigh skin temperature, mean body temperature, and skin vascular resistance between the two temperatures (9 and 15 °C) conditions at the 60-min recovery period after CWI. We chose 20 °C with a longer immersion time (15–20 min), 14 , 15 , 16 and our CCWI conditions in those studies resulted in temperature decreases of −4.7 °C in the abdomen and −5.9 °C in the lower legs at the end of immersion. Therefore, our CCWI might not be much different as a thermal effect compared to Choo's results.…”

“…We also observed that the T core and lactate values were highly correlated with cycling work efficiency 15 and peak pedal repetitions in a high-intensity intermittent exercise test. 16 …”
