Does Massage Help Heal Muscles Strained by Exercise? After exercise, massage is often used to relieve pain, and a recent study shows that it also may relieve inflammation and help muscles heal. In the study, eleven male participants who had just strenuously exercised had 10 minutes of massage on one quadricep and no treatment on the other, with treatment randomly assigned. After 2.5 hours, muscle biopsies were taken and production of the inflammatory cytokine interleukin-6 was measured relative to the resting level. The differences (control minus massage) are given in Table 1 below. 0.6 4.7 3.8 0.4 1.5 -1.2 2.8 -0.4 1.4 3.5 -2.8 Table 1: Inflammation in muscle: control minus massage Data approximated from summary statistics in Crane, et.al., "Massage Therapy Attenuates Inammatory Signaling After Exercise-Induced Muscle Damage", Science Translational Medicine, 1 February 2012.

Round your answer to three decimal places.Lizards and Invasive FireAnts This exercise addresses lizard behavior in response to re ants. The red imported re ant, Soienopsis invicta, is native to South America. but has an expansive invasive range, including much of the southern United States (invasion of this ant is predicted to go global]. In the United States. these ants occupy similar habitats as fence lizards. The ants eat the lizards and the lizards eat the ants. and in either scenario the venom from the re ant can be fatal to the lizard. A study1 explored the question of whether lizards learn to adapt their behavior if their environment has been invaded by re ants. The researchers selected lizards from an uninvaded habitat (eastern Arkansas) and lizards from an invaded habitat (southern Alabama. which has been invaded for more than 3'0 years) and exposed them to re ants. They measured how long it takes each lizard to ee and the number of twitches each lizard does. The data are stored in FireAnts. If lizards adapt their behavior to the re ants, then lizards from the invaded habitats should ee from the re ants faster than lizards from the uninvaded habitats. Test this hypothesis. Time to ee is measured in seconds, and lizards taking more than a minute to ee have recorded responses of 61 seconds. Let group 1 be lizards from invaded habitats and let group 2 be lizards from uninvaded habitats. Click here for the dataset associated with this question. Click here to access StatKey. 1Langkilde.
