Greater progression of athletic performance in older Masters athletes In recent years, fewer world records have been achieved in sports. On the other hand, the number of older athletes increased and their achievements were getting better.An American group examined the performance development over 100 m running, 400 m running and 100 m swimming from 1975 to 2013 for age-class athletes on world class levels.Over 100 m walk showed no improvement in the recent (fastest) group, but the times in the older age groups were getting better.
Especially in the higher age groups, the improvement was clearer with the athletes in the category 75-79 years showed the clearest improvement. The trend was for 100 m swimming and 400 m are very similar.The work can be found under https://pubmed.ncbi.nlm.nih.gov/25753790/
