Abstract
Context: Ice bags are often applied following exercise. It is known that exercise before cooling speeds heat removal, but does this exercise affect rewarming trends? Objective: Determine if exercise before an ice bag treatment effects interface (IF) and intramuscular (IM) during a 120-minute post-treatment period. Setting: Laboratory. Participants: Twelve physically active males (21.8 ± 1.7 y, ht: 183.3 ± 8.8 cm, mass: 87.4 ± 12.2 kg: skinfold: 23.6 ± 3.3 mm). Intervention: The exercise condition consisted of stationary cycling at 70% to 80% of their Karvonen predicted exercise heart rate, while the rest condition was supine lying. Each condition lasted 30 minutes. Treatment consisted of wetted ice bag (2000mL ice with 300mL water) compressed to the right anterior midthigh until the intramuscular temperature was 10°C below baseline. Rewarming temperatures were collected every 10 minutes for 120 minutes beginning immediately after treatment removal. Main Outcome Measures: IF and IM (2cm + ½ skinfold) temperatures to the nearest 0.1 °C. Results: Considering both the IF and IM rewarming trends separately, they are both affected by the exercise condition and time interaction (P < .00001 ). All conditions and treatment temperatures changed during the rewarming (P < .00001 ). Interface temperatures following exercise rewarmed faster and were higher than the rest condition at all times (P < .05 and smaller). Intramuscular temperatures where similar at the immediate, 10-, and 120-minutes times, while the exercise condition were higher than the rest at all of the other times (P = .042 and smaller). Conclusion: Following a 30-minute cardiovascular exercise bout both the interface and intramuscular rewarming trends after cooling the tissues 2 cm deep in the quadriceps to 10°C below baseline using a wetted ice bag treatment are different than no exercise before cooling.
