Serum Cardiac Troponin Response in Adolescents Playing Basketball

Abstract

Cardiac troponin release is generally found in adult athletes after continuous-type endurance exercises or sport competitions. The purpose of this study was to investigate whether the physical stress experienced by adolescents while playing basketball, an intense, intermittent-type sport, could induce transient elevations of the serum cardiac troponin T (cTnT) and I (cTnI). Serum cTnT and cTnI levels in 10 male adolescent players (age 15.0 +/- 0.7 yr) were assessed immediately before and at 2, 4 and 24 h after a game randomly selected from a preseason basketball-training program. At 4 h following the game, serum cTnT levels in four of the ten subjects were above the cutoff of 0.01 ng . ml (-1) for myocardial injury. Two of these four subjects had values higher than the acute myocardial infarction cutoff of 0.05 ng . ml (-1). In three of the four subjects, the serum cTnI was above the cutoff of 0.06 ng . ml (-1) for myocardial injury. Nevertheless, serum cardiac troponins at 24 h had returned to pre-exercise levels. These findings suggest that the physical stress encountered during intense, intermittent-type sports could cause release of cardiac troponins in some adolescents at low risk for cardiac disease.

Cardiac troponin I release after a basketball match in elite, amateur and junior players

“…The likely explanation for this discrepancy was the use of a simple pre-post exercise sampling regime in previous work. The current data supports Nie et al [13], in basketball players, and Carranza-García et al [10], in futsal players, who reported an increase in cTn several hours after simulated match. Consequently, our findings show, in line with continuous endurance exercise studies [4,20], the importance of obtained multiple blood samples during recovery to observe the maximum posteffort value.…”

“…For example, available scientific data related to cTn release after intermittent exercise, such as soccer [10,11], rugby [12], basketball [13] or floorball [14] is limited, often poorly controlled [12] and with limited sampling times post-exercise [11,12,14]. Consequently this has produced contradictory data.…”

Efficacy of Rhus coriaria (sumac) juice in reducing muscle pain during aerobic exercise

“…The data obtained matched with other researchers' results who reported a decrement in serum inflammatory markers including C reactive protein (CRP) by 25% after 28 days (8,14,19,21,23,26). The potential of skeletal troponin I and hyp as markers of muscle injury may be useful for assessing the effects of intense exercise for soft tissue injuries (31,48,51,55). So, in our study, troponin I and hyp values were measured in the serum of placebo and sumac groups' pre, during and post-exercise test.…”

The 99th percentile of reference population for cTnI and cTnT assay: methodology, pathophysiology and clinical implications

“…The kinetic profile of cTnI and cTnT circulating levels after strenuous exercise in apparently healthy subjects [25,40,[52][53][54][55][56][77][78][79][80][81][82][83][84][85][86][87][88][89][90] is different from that usually observed in patients with AMI. It is well known that circulating levels of cTnI and cTnT in patients with uncomplicated type 1 AMI usually peak between 12 and 36 h from beginning of thoracic pain, gradually returning to below the 99th URL value within 5-7 days [1,3,40,76].…”
