TL;DR: Previous research from this group has shown a decreased PPT and CPM, indicating greater pain sensitivity, across all ages during an ultra-marathon, but clearly a difference between age groups in the degree of these changes. (via Semantic Scholar)

RESULTS: The Post PPT and CPM were significantly decreased (p<0.05) for both age groups, indicating greater pain sensitivity. The age group analysis (<40 versus >40) showed a decrease in Delta PPT in the older age group: (Mean Delta <40 years = 149.40 kPa, Mean Delta >40 years = 48.38 kPa t(42)= 2.69; p<.05. A similar decrease was found in Delta CPM: (Mean Delta <40 years = 31.75 kPa, Mean Delta >40 years = 11.69 kPa t(42)= 2.03; p<.05. CONCLUSION: Previous research from our group has shown a decreased PPT and CPM, indicating greater pain sensitivity, across all ages during an ultra-marathon. In this present study we have seen similar decreases in PPT and CPM but clearly a difference between age groups in the degree of these changes. Further research is required to determine how factors of immunosenescence, directly or indirectly, may affect the age group variations in pain during an ultra-marathon.
