Progression records for shot put must be set in properly conducted, official competitions under the standing IAAF rules unless modified by World Masters Athletics. Divisions are based upon the age of the athlete, with the category giving a minimum and implying a maximum age (5 years higher than the minimum). So, for example, the M35 division consists of male athletes who have reached the age of 35 but have not yet reached the age of 40, so exactly from their 35th birthday to the day before their 40th birthday.[1]
Weights thrown vary with the division in the following way:[1]
Division
Weight thrown
M35
16 lb/7.260 kg
M40
16 lb/7.260 kg
M45
16 lb/7.260 kg
M50
6 kg
M55
6 kg
M60
5 kg
M65
5 kg
M70

M75

M80

The youngest divisions throw exactly the same 16 lb/7.260 kg implement as the Open division. The records are as follows.[2][3][4]

Oldfield improved the record three times during his series on his 35th birthday in Berkeley, California. His 22.19 was just 3 cm short of the standing official world record, though he had thrown 22.86 five years earlier, but that throw had been disallowed because Oldfield was a professional, against the rules at that time.
