For the aforementioned physiological effects of cry otherapy, functional performance was affected by cold's negative influences (e.g. changes in strength, tissue stiffness, altered stretch-reflex). However, both the agility and speed functional performance tests returned to base- line levels much sooner than vertical jump. It is possible the quicker return to baseline times may be attributed to increased tissue rewarming through increased blood flow to the working muscles during exercise. Research has demonstrated moderate exercise significantly enhanced tissue rewarming (Myrer et al., 2001; Palmer and Knight 1992). Myrer et al. (2001) noted 11 minutes following treatment, an ice-exercise group was .61°C colder than pretreatment levels while an ice-rest group was 8.05°C colder. Significant differences also existed 30 minutes following treatment. In the ice-exercise group, tempera
