Background: We aimed to examine the effects of cool-down exercise and cold-water immersion therapy on agility, speed, power, balance, and sport-specific skill performance in college soccer players, and to provide baseline data for the development of effective recovery programs. Methods: In August 2020, 21 male college soccer players in Seoul, Korea, were randomly divided into the following groups: control group (CG, n=7), cool-down exercise group (CDG, n=7), and cool-down exercise plus cold-water immersion group (CDCWG, n=7). Agility, speed, power, balance, and sport-specific skill performance were assessed before and after the intervention. Results: No significant differences in Southeast Missouri (SEMO) Agility Test, 20-m sprint test, vertical jump test, or Y-balance test (right) were observed among the groups; however, there was a significant effect of time (P<0.05) and a significant time × group interaction (P<0.05). Significant effects of time (P<0.001), group (P=0.043), and a time × group interaction (P=0.009) were observed in the Y-balance test (left). There were no between-group differences in the 22-m dribble test, shooting test (left), or shooting test (right); however, there were significant effects of time (P<0.05) and significant time × group interactions (P<0.05). No significant effects of group or time × group interactions were observed for the kicking test (left or right); however, there were significant effects of time (P<0.001). Conclusion: Addition of cold-water immersion therapy to a recovery program including cool-down exercise can promote recovery of basic and sport-specific abilities among college soccer players.

Purpose: The purpose of this study is to compare two cold water immersion (CWI) protocols, continuous and fractionated, to optimize the recovery of Handball players after on recovery from exercise resulting in exercise-induced muscle damage. Material: Ten male Handball players (age: 15 ± 1.4 years, mass index: 67.2 ± 5.1 kg, height: 176.6 ± 7.30) voluntarily participated in the study. After three 90-minute training sessions (average heart rate 160 ± 15.81, 156 ± 5.53 and 156 ± 12.24 bpm) per week, participants were divided into 03 groups. The first experimental group (GE1) in continuous immersion (CWIC) of (12 minutes, 12± 0.4° C), a second experimental group (GE2) in fractional immersion (CWIF) of (4 x 2 min at 12 ± 0.4° C + 1 min out of water) and a control group (GC) in passive recovery. Body mass indices (BMI), countermovement (Countermovement jump) and muscle pain (Intensity of pain in the thighs) were measured. Results : The results concerning the percentage differences in the variation of the CMJ occurred respectively at 24h (Z = 12.62, p = 0.004) and 48h (Z = 16.22, p <0.001) compared to the control group. In addition, the results for muscle volume did not report any significant interaction (F (5.64) = 3.42, p = 0.078). The results of both protocols showed their effectiveness in reducing pain intensity by 24 and 48 hours after intense training (F (3.54) = 2.91, p = 0.016, p2 = 0.24). Conclusion: In conclusion, continuous and fractionated cold water immersion is beneficial for neuromuscular recovery 24 hours after intense exercise. The results also demonstrate a rapid recovery of handball players from their physical potential required in high level competitions.

Summary Study aim: To investigate the effect of cold water immersion (CWI) on muscle damage indexes after simulated soccer activity in young soccer players. Material and methods: Eighteen professional male soccer players were randomly divided into two groups: CWI (n = 10, age 19.3 ± 0.5, body mass index 22.2 ± 1.3) and control (n = 8, age 19.4 ± 0.8, body mass index 21.7 ± 1.5). Both groups performed a simulated 90-minute soccer-specific aerobic field test (SAFT90). Then, the CWI group subjects immersed themselves for 10 minutes in 8°C water, while the control group subjects sat passively for the same time period. Blood samples were taken before, immediately after, 10 minutes, 24 hours and 48 hours after the training session in a fasted state. Blood lactate, creatine kinase (CK) and lactate dehydrogenase (LDH) enzyme levels were measured. Results: Lactate, CK and LDH levels increased significantly after training (p < 0.001). There were significant interactions between groups and subsequent measurements for CK (p = 0.0012) and LDH (p = 0.0471). There was no significant difference in lactate level between the two groups at any aforementioned time. Conclusion: It seems that CWI after simulated 90-minute soccer training can reduce the values of muscle damage indexes in soccer players.
