Muscle fibers con- tain three metabolic pathways for producing ATP: crea- tine phosphate, rapid glycolysis, and aerobic oxidation (Demaree et al, 2001; Rupp, 2001). INTRODUCTION THREE ENERGY SYSTEMS ARE RESPONSIBLE FOR THE RESYNTHESIS OF ATP Regular physical activity is an important component of a healthy lifestyle. Increases in physical activity Creatine Phosphate System and cardiorespiratory fitness have been shown to When limited stores of ATP are nearly depleted reduce the risk of death from coronary heart disease as during high-intensity exercise (5–10 s), the creatine well as from all causes.

To provide ATP at a very rapid rate; however, as there is reflect this evidence, the Centers for Disease Control a limited supply of CP in the muscle the amount of and Prevention (CDC) and the American College of ATP that can be produced is also limited.

Research has also examined the long-term consequences of pain at developmental stages be- 5 discount celebrex 100mg with visa. For example order 100 mg celebrex overnight delivery, Grunau and her colleagues have con- ducted a series of studies comparing the pain responses of former preterm and full-term children postinfancy. This research has shown lower levels of reactivity in response to everyday pain at age 18 months among the low birthweight children (Grunau, Whitfield, & Petrie, 1994), a higher incidence of somatization among 4. Another biological factor that is thought to contribute to age-related dif- ferences in children’s pain experiences is body surface area (BSA). In their study of needle pain ratings of children between the ages of 3 and 17 years, Goodenough et al. The authors hypothesized that developmental ana- tomical differences may form a component of age-related responses to pain in children (Goodenough et al. Future research is needed to explore age differences in physiological factors that may relate to pain across in- fancy, childhood, and adolescence. Age Differences in Pain Assessment During Childhood There exist a variety of measures to assess pain in children, including self- report, behavioral, and physiological measures. Comprehensive reviews of these measures are available elsewhere (Finley & McGrath, 1998; McGrath & Gillespie, 2001). Due to its subjective nature, self-reports are generally considered to be the gold standard in pediatric pain assessment, where possible (Merskey & Bogduk, 1994). Examples of self-report tools include numeric ratings scales, faces scales, and colored analogue scales (Cham- pion, Goodenough, von Baeyer, & Thomas, 1998). Assessment measures de- signed specifically for adolescents are also available (Savedra, Tesler, Hol- zemer, Wilkie, & Ward, 1990) as are more comprehensive chronic pain inventories (Varni, Thompson, & Hanson, 1987). However, cognitive and emotional limitations may hinder the appropriateness of use of self-report measures with some children. Although researchers have employed self- report measures with children as young as 3 years of age (Goodenough et al. For example, young children tend to rely on the extremes of ratings scales (Chambers & John- ston, 2002; von Baeyer et al. Future research is needed to examine cognitive skills necessary for providing accurate self-reports of pain, meth- 124 GIBSON AND CHAMBERS ods to estimate the age at which these skills emerge, and ways to train young children to more appropriately use self-report measures. These range from detailed coding of facial expressions (Craig, 1998) to quantification of broad band behaviors (McGrath, 1998), such as screaming or flailing. Behavioral measures have typically been developed for a partic- ular developmental period. For example, specific behavioral measures exist for assessment of premature infants (e. Behavioral measures are especially valuable in the case where self-reports of pain are not possible (e. Research has generally indicated that observer ratings underestimate children’s pain in- tensity (Chambers, Reid, Craig, McGrath, & Finley, 1998), although no re- search has documented age-dependent differences in agreement between observer and child reports of pain. Physiological measures are also employed in the assessment of pain in children (Sweet & McGrath, 1998). These include heart rate, respiratory rate, and skin blood flow, among others. Research has generally shown that such physiological responses tend to habituate over time and are not spe- cific to pain, although they can be useful in providing complementary infor- mation regarding a child’s pain experience (Sweet & McGrath, 1998). As indicated earlier, age-related differences in children’s physiological respon- siveness to pain have been reported (Bournaki, 1997). Regardless of the specific type of pain measure of interest, it is of impor- tance to give consideration to the unique developmental features of the measure and its appropriateness for use with children of particular ages. Al- though it is helpful that available measures have been tailored to children of specific ages, this approach may, in part, hinder our ability to conduct com- parisons of children’s pain responses across developmental periods.
