Small regulatory peptides encoded within the mitochondrial genome (mitochondrial-derived peptides) have been shown to have cellular cyto- and metabolo-protective roles that parallel those of exercise. Here we provide evidence that humanin and SHLP6 are exercise-sensitive mitochondrial derived peptides. Studies to determine whether mitochondrial-derived peptides play a role in regulating exercise-induced adaptations are warranted.

Background: Platelets (plts) are involved in thrombosis. However, intense exercise can affect the number and activation of plts. Objectives: The purpose of this study was to compare the effects of acute high-intensity interval exercise performed in the morning and the evening on plt indices and exercise-induced thrombocytosis. Methods: Eleven healthy young adult active male (70.60 ± 8.26 kg) subjects performed high-intensity interval exercise (40 m shuttle sprints at maximum speed for 20 m in a track) on two distinct experimental days (at 8:00 - 9:00 and 15:00 - 16:00) separated by a three-day washout period. Blood samples were taken before and immediately after each exercise session from the antecubital vein by a repetitive venous puncture in a sitting position. Results: Data indicated that after high-intensity interval exercise, there were increases in the number of plts in the morning (P = 0.03) and the evening (P = 0.001). In addition, it was observed that mean plt volume and plt larger cell ratio was higher in the morning pre-test and post-test (P < 0.05), while plt distribution width was only higher in the morning pre-test (P = 0.03). Conclusions: It seems that it may be safer to perform high-intensity interval exercise in the evening due to lower mean plt volume, plt larger cell ratio, plt distribution width, and risk of thrombosis.

Aerobic exercise at approximately 70% of maximal aerobic capacity moderately reduces pain sensitivity and attenuates pain, even after a single session. If the analgesic effects depend on exercise intensity, then high-intensity interval exercise at 85% of maximal aerobic capacity should further reduce pain. The aim of this study was to explore the exercise-induced analgesic effects of high-intensity interval aerobic exercise and to compare them with the analgesic effects of moderate continuous aerobic exercise. Twenty-nine young untrained healthy males were randomly assigned to aerobic-continuous (70% heart rate reserve (HRR)) and interval (4 × 4 min at 85% HRR and 2 min at 60% HRR between cycles) exercise modes, each lasting 30 min. Psychophysical pain tests, pressure and heat pain thresholds (HPT), and tonic heat pain (THP) were conducted before and after exercise sessions. Repeated measures ANOVA was used for data analysis. HPT increased (p = 0.056) and THP decreased (p = 0.013) following exercise unrelated to exercise type. However, the main time effect (pre-/postexercise) was a trend of increased HPT (45.6 ± 1.9 °C to 46.2 ± 1.8 °C; p = 0.082) and a significant reduction in THP (from 50.7 ± 25 to 45.9 ± 25.4 numeric pain scale; p = 0.043) following interval exercise. No significant change was found for the pressure pain threshold following either exercise type. In conclusion, interval exercise (85% HRR) has analgesic effects on experimental pain perception. This, in addition to its cardiovascular, muscular, and metabolic advantages may promote its inclusion in pain management programs.
