Resumen
El texto original del estudio, en el idioma en que se publicó.
Aims
The main aim was to compare aerobic performance data, determined before «period1» and after «period2» cold water immersion in two groups of footballers (CWI and no-CWI groups).
Methods
This is an experimental study with matching and randomization. The 20 male footballers, aged 17 to 20 years, were divided into two groups (n = 10 for each) following a random draw. The two groups were age-, height- and weight matched. 1000-m race was made during the two periods. Heart-rate (HR, % of theoretical maximum HR) and hemoglobin oxygen saturation (Oxy-sat, %) were measured before and after the race, and the time of the race (min) was noted. An Oxy-sat decrease > 4 points retained the diagnosis of exercise-induced desaturation. Eight CWI sessions (one per week), until the hip in a standing position (10 min; temperature: 11-12 °C) were performed.
Results
The two groups were age-, height- and weight matched. Comparatively to the race time of «period1», this of «period2» was decreased in the CWI group (3.21±0.04 vs. 3.15±0.04 min) and was increased in the no-CWI group (3.23±0.05 vs. 3.27±0.07 min). Comparatively to the HRs (before, after the race) of «period1», these of «period2» were decreased in the CWI group (36±1 vs. 34±1%; 56±3 vs. 44±2%) and were increased in the no-CWI group (35±2 vs. 36±1%; 55±2 vs. 57±2%). Comparatively to the after race Oxy-sat' of the «period1», this of «period2» was increased in the CWI group (96±1 vs. 98±0%) and was decreased in the no-CWI group (96±1 vs. 95±1%). While in the CWI group, the percent of desaturators was decreased between «period1» and «period2» (30 vs. 0%), in the no-CWI group, percentages remained similar (50 vs. 90%).
Conclusion
CWI improves aerobic capacity and muscle strength of young footballers.
