Andrea Zorzi wrote an (very brief) analysis of modern volleyball that appeared today on FIVB website. Among other things that I may or may not agree with, he stated that serving speeds are “…about 10km/h faster than they used to be…”. This is true. When the FIVB changed to the current ball, the serving speed was around 110 km/h. It is now in the low 120s.
However… my recollection is that at the Olympic Games in 2000, with the old Mikasa leather ball, the fastest serves were around 127/128 km/h, from Iakovlev. Also at around the same time in Italy, using the old Molten leather balls, the fastest serves were in the 138 km/h range, from Dineikine and Iakovlev. When they first changed to synthetic balls in 2001, the speeds dropped and again in 2008.
Does anyone have some documentation or old articles or videos on this topic?
