Who is Emily Seebohm?

Emily Seebohm is a backstroke phenomenon from Australia, who also competes in freestyle, butterfly and IM events. She holds Australian records for individual events, including all long course and short course backstroke events, and 200IM (SC), as well as relay events, including 400 medley relay (LC) and 200 medley relay (SC).

In 2009, Emily was awarded the Medal of the Order of Australia for services to sport as a gold medalist at the 2008 Olympic Games. She was Swimming Australia’s 2014 Short Course Swimmer of the Year, and in 2017, she was named Female Australian Swimmer of the Year, an award she shared with Bronte Campbell in 2015.

Emily’s Metrics

We looked at Emily’s 100m backstroke metrics from the 2016 Rio Olympic Games, 2017 FINA World Championships, and 2018 Commonwealth Games, to analyze how her metrics and strategies changed over time, and how these impacted her overall performances.

Stroking Metrics



Emily’s backstroke speed improved at the 2017 FINA Championships and 2018 Commonwealth Games compared to her performance at the 2016 Olympics. Interestingly, she split her first 50 slightly faster at the 2016 Olympics, but swam better times in 2017 and 2018.

The improvements in her overall speed came from her increased speed on the second half of the 2017 and 2018 races. In both these years, her faster speed on the second lap resulted in splits around 0.7 seconds lower than in 2016, which offset her slightly slower starts, leading to faster times and better final standings.   

Stroke rate and DPS

Seebohm_Stroke Rate and DPS

Across all 3 competitions, Emily’s stroking strategy was to pull slower, but longer and more powerful strokes. Her DPS was consistently above her heat’s average, and she had a slower stroke rate than most of her competitors.

Her stroke rate remained relatively steady from one year to the next, but her DPS simultaneously increased. 

Stroke Index

The improvements in her speed, along with the increase in her DPS resulted in higher stroke index from 2016 to 2018. She had one of the most efficient backstrokes of the heat in all 3 races, and she improved her stroke efficiency even more from year to year. 

Transition Metrics

Time Underwater and Turn Time

Seebohm_Turn Time and Time Underwater

In 2016 and 2017, Emily had the slowest turn time in the field. She improved on this fairly significantly in 2018, where she had the quickest turn time in her heat.

On average, she spent less time underwater than her competitors, even in 2017, where her time underwater was around half a second longer than in 2016 and 2018.



Good pacing is essential for a fast race, even for distances as short as 100m. 

Emily held back slightly on the first lap of the 100m backstroke at the 2017 FINA Championships and 2018 Commonwealth Games, but she was able to finish her races stronger, which ultimately led to faster times.

Changes in just a single metric, or a combination of a few, can lead to overall progress – improving metrics is not all or nothing.

Emily’s better pacing strategy was not the only factor in the improvements in her overall performance. Her DPS and stroke index improved after the 2016 Olympics, and though her stroke rate remained nearly the same, the changes in her DPS and stroke index were enough to improve her speed, leading to faster times and podium finishes.

Knowing your strengths, and improving on them further, produces great results.

Emily pulls powerful and efficient strokes. This strategy earned her a spot at the 2016 Olympic finals. In the years following the Olympics, she strengthened her DPS and improved her backstroke efficiency, dropping her times in these races.
