Can Wayde van Niekerk repeat his amazing feat from the 2016 Olympics – now five years later – at the next Games?

It is a year later, but the Tokyo 2020 Olympics finally started on Friday, 23 July 2021. In team South Africa, a couple of the athletes and management, many of them medal contenders, call themselves Kovsies.

From 1 August, the progress of the country’s golden boy, Wayde van Niekerk, will be closely followed when he tries to hold on to the title as Olympic 400 m champion – he is still the world record holder (set at the 2016 Games). The final of the 400 m is scheduled for 5 August.

One of only five female athletes in the South African team, Gerda Steyn will compete in the marathon on 7 August. This is her first time at the Olympics. 

She is in red-hot form. In April, she broke a 25-year record in Italy when she ran the fastest-ever marathon by a South African woman, finishing in 2:25:28. She is the defending Comrades and Two Oceans champ.

Protea hockey player, Nicole Erasmus, will become a fourth-generation Olympic contender in her family. Her mother, Lynne Walraven (née Tasker) was a Zimbabwean swimmer, her great-uncle, Anthony Tasker, was a member of the South African rowing team, and her great-great-uncle, Frank Rushton, was a South African hurdles athlete. 

From 26 to 28 July, the South African sevens rugby team, with former Shimlas Chris Dry as a team member and Neil Powell as head coach, will aim to improve on their bronze medal achieved in 2016. Powell was also the head coach at the time, and another former Kovsie, Philip Snyman, captained the Blitzboks.

Kate Murray (formerly Roberts), head coach and high-performance manager of Triathlon South Africa, will act as the SA triathlon coach. She is a double Olympic participant, having raced for South Africa at the 2008 and 2012 Olympic Games.

Research on locomotion of giraffes valuable for conservation of this species

approximately 20 - 30 m away. When the
drone moves closer, they will revert
to galloping.

The meaning of the Arab term Giraffe Camelopardalis is ‘someone who walks fast’. It is precisely this locomotion of their longnecks that encouraged researchers, Dr Francois Deacon and Dr Chris Basu, to study the animals more closely.

Despite the fact that giraffes are such well-known animals, very little research has been done on the manner in which these graceful animals locomote from one place to the next. There are only two known ways of locomotion: the slower lateral walking and the faster galloping. Most animals use these ways of moving forward. It is unknown why giraffes avoid intermediate-speed trotting.

Research of great value to the industry

Research on the manner in which giraffes locomote from one place to the next will assist the industry in understanding aspects such as their anatomy and function, as well as the energy they utilise in locomoting from one place to another. Information on the latter could help researchers understand where giraffes fit into the ecosystem. This data is of great value for large-scale conservation efforts.

Universities working together to collect data

Dr Basu, a veterinarian at the Royal Veterinary College in the UK, has studied the animals at a zoo park in the United Kingdom. He visited the University of the Free State (UFS) in order to expand his fieldwork on the locomotion of giraffes. This study was done in cooperation with Dr Deacon from the Department of Animal, Wildlife, and Grassland Sciences at the UFS. Dr Deacon is a specialist in giraffe habitat-related research in South Africa and other African countries.

The fieldwork for the research, which was done in the Woodland Hills Wildlife Estate and the Willem Pretorius Nature Reserve, preceded research on the movement and the forces involved in the locomotion of giraffes. Due to the confined fenced area in the zoo park, it was practically impossible to study the animals at speed. “The study of actions ‘faster than walking’ is crucial for gathering data on, inter alia, the frequency, length, and time associated with each step.


Technology such as drones offers unique
opportunities to study animals like giraffes.



Technology used to ensure accuracyTechnology such as drones offers unique opportunities to study animals like giraffes. Apart from the fact that it is possible to get high-quality video material of giraffes – moving at speed – it is also a very controlled device that ensures the accuracy of data.

It is the first time ever that a study has been done on the locomotion of giraffes with this level of detail.
Research on the study will be published in the Journal of Experimental Biology.

The project was approved by the UFS ethics committee.
