| ABSTRACT | |||
| The purpose of the study was to determine the effects of cold
water immersion (CWI) performed immediately or 3 h after a high intensity
interval exercise session (HIIS) on next-day exercise performance. Eight
male athletes performed three HIIS at 90%VO2max velocity followed
by either a passive recovery (CON), CWI performed immediately post-exercise
(CWI(0)) or CWI performed 3 h post-exercise (CWI(3)). Recovery trials were
performed in a counter balanced manner. Participants then returned 24 h
later and completed a muscle soreness and a totally quality recovery perception
(TQRP) questionnaire, which was then followed by the Yoyo Intermittent Recovery
Test [level 1] (YRT). Venous blood samples were collected pre-HIIS and pre-YRT
to determine C-Reactive Protein (CRP) levels. Significantly more shuttles
were performed during the YRT following CWI(0) compared to the CON trial
(p=0.017, ES = 0. 8), while differences between the CWI(3) and the CON trials
approached significance (p = 0.058, ES = 0.5). Performance on the YRT between
the CWI(0) and CWI(3) trials were similar (p = 0.147, ES = 0. 3). Qualitative
analyses demonstrated a 98% and 92% likely beneficial effect of CWI(0) and
CWI(3) on next day performance, compared to CON, respectively, while CWI(0)
resulted in a 79% likely benefit when compared to CWI(3). CRP values were
significantly lower pre-YRT, compared to baseline, following CWI(0) (p =
0.0.36) and CWI(3) (p = 0.045), but were similar for CON (p = 0.157). Muscle
soreness scores were similar between trials (p = 1.10), while TQRP scores
were significantly lower for CON compared to CWI(0) (p = 0.002 ) and CWI(3)
(p = 0.024). Immediate CWI resulted in superior next-day YRT performance
compared to CON, while delayed (3 h) CWI was also likely to be beneficial.
Qualitative analyses suggested that CWI(0) resulted in better performance
than CWI(3). These results are important for athletes who do not have immediate
access to CWI following exercise. Key words: Recovery, cold water immersion, C-Reactive Protein, yoyo test. |
