Abstract

Purpose<\/h3>\n

We evaluated whether repeated high-intensity interval exercise (HIIE) influences plasma oxytocin (OT) concentration in healthy men and, given that OT is mainly synthesized in the hypothalamus, we assessed the concentration difference between the arterial (OTART<\/sub>)\u00a0vs.<\/em>\u00a0the internal jugular venous OT concentration (OTIJV<\/sub>). Additionally, we hypothesized that an increase in cerebral OT release and the circulating concentration would be augmented by repeated HIIE.<\/p>\n

Methods<\/h3>\n

Fourteen healthy men (age 24 \u00b1 2 yrs.; mean \u00b1 SD) performed two identical bouts of HIIE. These HIIE bouts included a warm-up at 50-60% maximal workload (W<\/em>max<\/sub>) for 5 min followed by four bouts of exercise at 80-90%\u00a0W<\/em>max<\/sub>\u00a0for 4 min interspersed by exercise at 50-60%\u00a0W<\/em>max<\/sub>\u00a0for 3 min. The HIIE bouts were separated by 60-min of rest. OT was evaluated in blood through radial artery and internal jugular vein catheterization.<\/p>\n

Results<\/h3>\n

Both HIIE bouts increased both OTART<\/sub>\u00a0(from 3.9 [3.4-5.4] (median [IQR]) to 5.3 [4.4-6.3] ng\/ml in the first HIIE,\u00a0P<\/em>\u00a0< 0.01) and OTIJV<\/sub>\u00a0(from 4.6 [3.4-4.8] to 5.9 [4.3-8.2] ng\/ml,\u00a0P<\/em>\u00a0< 0.01), but OTART-IJV<\/sub>\u00a0was unaffected (from -0.24 [(-1.16)-1.08] to 0.04 [(-0.88)-0.78] ng\/ml,\u00a0P<\/em>\u00a0= 1.00). The increased OT levels were similar in the first and second HIIE bouts (OTART<\/sub>P<\/em>\u00a0= 0.25, OTIJV<\/sub>P<\/em>\u00a0= 0.36).<\/p>\n

Conclusions<\/h3>\n

Despite no change in the cerebral OT release via the internal jugular vein, circulating OT increases during HIIE regardless of the accumulated exercise volume, indicating that OT may play role as one of the exerkines.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"excerpt":{"rendered":"
