Study Notes
World Records in Sprinting and Swimming
- Elite athletes at the 2024 Summer Olympics are anticipated to break world records in various sports.
- 100-meter dash and 50-meter freestyle swimming have not seen new world records in over a decade.
100-Meter Dash Records
- Current men's record: Usain Bolt (Jamaica) – 9.58 seconds, set in 2009, with a top speed of 45 km/h (28 mph).
- Current women's record: Florence Griffith Joyner (USA) – 10.49 seconds, set in 1988.
- Potential maximum human speed could reach 60 km/h (37 mph), completing 100 meters in approximately 5.625 seconds.
- Sprinting speed is influenced by technique and biomechanics, emphasizing force application and minimal ground contact time during runs.
- Historical progress: Men's 100-meter times have decreased by about one second since recordkeeping began in 1912; women's times have improved by approximately three seconds since 1922.
Validity of Existing Records
- Joyner’s record faces scrutiny due to wind conditions during competition.
- Transition to electronic timing in 1968 introduced greater precision and may have affected the perceived progression of record times.
50-Meter Freestyle Swimming Records
- Current men's record: César Cielo Filho (Brazil) – 20.91 seconds, set in 2009; slower than Bolt’s average speed during 100-meter dash.
- Current women's record: Sarah Sjöström (Sweden) – 23.61 seconds, set in 2023.
- Both records are about three seconds faster than original records from the 1970s.
Factors Influencing Swimming Speed
- Swimming is inherently slower than running due to water density and increased drag from body shape, particularly the head.
- 2008-2009 saw a surge of records due to innovative swimsuits designed by Speedo, which were subsequently banned in 2010.
- Optimal swimming technique involves minimizing drag by lying parallel to the water and maximizing stroke efficiency through high elbow positioning and fast stroke rates.
