“…Intense physical exercise stimulates the HPA and HPG axes through several mechanisms that are not fully understood. Increase in plasma lactate and humoral mediators such as interleukins and angiotensin II have been implicated in the activation of the HPA axis during intense physical exercise [18]. The beta-endorphins, factors released into the circulation during intense exercise, influence the hypothalamic functions, including the regulation of reproduction via their inhibitory effect on GnRH release [19].…”

Abstract:This critical review discusses the use of the testosterone/cortisol ratio in the studies of athletic performance and sports physiology. Although in most of the time physical exercise is beneficial to health, it can also be seen as a "stressor" both in men and in women. It is not completely known at what level this "physical stress" ends up its beneficial effects and begins to impair health status. In search for this putative turning point, several markers have been put forward in the last decades. One of these markers is the ratio between testosterone, considered as an anabolic hormone, and cortisol, considered as a catabolic one. Whether in search for an anabolic internal environment for strength training or to avoid performance decline during aerobic workout, the testosterone/cortisol ratio has been considered as an important physiological variable to gauge individual conditioning and responses.

Latar belakang. Gangguan Pemusatan Perhatian/Hiperaktivitas (GPP/H) merupakan gangguan neuropsikiatrik yang disinyalir memberikan dampak negatif bagi kesehatan ketika dewasa. Tujuan. Penelitian ini dilakukan untuk mengetahui karakteristik fisik dan sosiodemografis anak dengan GPP/H, dan pengaruh kepatuhan latihan fisik terhadap perubahan prilaku pada anak GPP/H. Metode. Penelitian eksperimen, pre-post design dengan perlakuan latihan SKJ '88 dilakukan pada subjek penelitian di Sekolah Khusus Al-Ikhsan selama 8 minggu. Pemilihan sampel digunakan metode tanpa acak (non probability sampling) dengan jenis metode consecutive sampling, yaitu semua anak dengan GPP/H yang memenuhi kriteria pemilihan akan diikutsertakan dalam penelitian. Analisis data digunakan uji t satu sampel dan uji t berpasangan. Hasil. Di antara 40 subjek penelitian, didapatkan 19 (47,5%) sangat patuh dan 21 (52.5%) patuh. Nilai selisih rata-rata skor SPPAHI orangtua (SPPAHI-O) tiap tipe GPP/H didapatkan inatentif 46,2 (p<0,001), hiperaktif-impulsif 60,4 (p<0,001), campuran 47,6 (p<0,001) ditunjukkan adanya perbaikan perilaku di rumah. Nilai selisih rata-rata skor SPPAHI guru (SPPAHI-G) tiap tipe GPP/H didapatkan inatentif 41,7 (p<0,001), hiperaktif-impulsif 56,8 (p<0,001), campuran 42,2 (p<0,001) ditunjukkan adanya perbaikan perilaku di sekolah. Kesimpulan. Hasil penelitian menunjukkan kepatuhan melakukan latihan SKJ '88 berpengaruh terhadap perbaikan perilaku di rumah (p<0.001) dan di sekolah (p<0.001) pada kelompok subjek sangat patuh maupun patuh. Sari Pediatri 2016;18 (2) Background. Attention-Deficit/Hyperactivity Disorder (ADHD) is a neuropsychiatric disorder in children that allegedly affect their health in adulthood.Objective. This research was aimed to find physical characteristic and sociodemography of the children of ADHD and to know the influence of exercise due to changes of behaviour children with ADHD. Methods. This study was experimental research with pre and post design by giving SKJ '88 excercise to the subject of study at Sekolah Khusus Al-Ikhsan for 8 weeks. Sample selection was done without random (nonprobability sampling) with consecutive sampling method types, all children with ADHD who met the selection criteria will be included in the study.

“…Physical activity is widely known to be a powerful stimulus of the hypothalamic-pituitaryadrenal (HPA) and noradrenergic systems (7). Physical and mental stress each elicits physiologic responses that are mediated through the autonomic nervous system and endocrine system (8).…”
