The purpose of this study was to establish the validity and reliability of the newly developed surface electromyography (sEMG) device (PSL-EMG-Tr1) compared with a conventional sEMG device (BTS-FREEEMG1000).\n                    <jats:italic>Methods<\/jats:italic>\n                    . In total, 20 healthy participants (10 males, age 30.3\u2009\u00b1\u20092.9 years; 10 females, age 22.3\u2009\u00b1\u20092.7 years) were recruited. EMG signals were recorded simultaneously on two devices during three different isometric contractions (maximal voluntary isometric contraction (MVIC, 40% MVIC, 80% MVIC)). Two trials were performed, and the same session was repeated after 1 week. EMG amplitude recorded from the dominant biceps brachii (BB) and rectus femoris (RF) muscles was analyzed for reliability using intrasession intraclass correlation coefficient (ICC). Concurrent validity of the two devices was determined using Pearson\u2019s correlation coefficient.\n                    <jats:italic>Results<\/jats:italic>\n                    . Nonnormalized sEMG data showed moderate to very high reliability for all three contraction levels (ICC\u2009=\u20090.832\u20130.937 (BB); ICC\u2009=\u20090.814\u20130.957 (RF)). Normalized sEMG values showed no to high reliability (ICC\u2009=\u20090.030\u20130.831 (BB); ICC\u2009=\u20090.547\u20130.828 (RF)). sEMG signals recorded by the PSL-EMG-Tr1 showed good to excellent validity compared with the BTS-FREEEMG1000, at 40% MVIC (\n                    <jats:italic>r<\/jats:italic>\n                    \u2009=\u20090.943 (BB),\n                    <jats:italic>r<\/jats:italic>\n                    \u2009=\u20090.940 (RF)) and 80% MVIC (\n                    <jats:italic>r<\/jats:italic>\n                    \u2009=\u20090.983 (BB);\n                    <jats:italic>r<\/jats:italic>\n                    \u2009=\u20090.763 (RF)).\n                    <jats:italic>Conclusions<\/jats:italic>\n                    . The PSL-EMG-Tr1 was performed with acceptable validity. Furthermore, the high accessibility and portability of the device are useful in adjusting the type and intensity of exercise.\n
