Tokyo 2020's weekly series, which covers each event, is a great way for beginners to learn about artistic gymnastics during an Olympic Games.This week, we're talking about uneven bars.

.There is no shame in it; everyone has a different way of patching themselves up. Try not to get caught up in the madness involved in the preparation of the bars before each routine.

In most bar events for both genders, every gymnast has an exact way of preparing the apparatus - only women do uneven bars, but it true for most bar events for both genders as well.The gymnasts aren't falling off, but the scraping, chalking, and water-spraying between each routine can resemble a whirling dervish of a chef in the kitchen.

In between presenting the gymnast to the judges and taking a deep breath, there is a momentary pause.

Aliya Mustafina, Rio 2016 bars champion and yet another gymnastics fan favourite, showed off her leg extension and toe point during her bars routine.

What to look out for

Exercisers must string together alternating movements in both directions and between the different height bars - the low bar is approximately 170 cm high and the top bar is approximately 250 cm high - with a distance between the two of 180 cm.Most of the time, elements with twists, somersaults, grip changes, and high flight receive the highest scores.A more difficult move is always better, and if you can combine it with another difficult move, then you - quite rightly - get a bonus.

Routines that look short have fewer superfluous moves than those that add little value. They simply make it easier to move into the next move.

On all apparatus, these days, scores are composed of an execution score (the E score) and a difficulty score (the D score).Viewers can also view the E score if they are fans of the old 10/10 grading system.As the competition progresses, judges will remove marks from participants who lose form, such as toes that are not pointed or falls from the apparatus.

Judges calculate the D score by using a Code of Points, which is replaced every Olympic cycle, which assigns a value to each move the gymnast performs. .She scores 6.800 in difficulty and 9.100 in execution.

Here comes a science bit

This Bluffer's guide series has covered a couple of events in Tokyo 2020, so we bring you something a little more technical - a move on bars called the Nabs.It was originally performed by Tatiana Nabieva, a retired Russian gymnast, in 2010.

We're going to look at the move at the beginning of the routine where she puts her toes on the bars, then flies in a straight line over the bar to catch again.

As soon as a gymnast competes a new move successfully for the first time, the move is named after them, therefore this move is called the Nabieva, also known as Nabs among the gymnastics community.There are still only a few gymnasts who can complete this move.A video from 2010 shows Nabieva debuting the move.

For a fuller explanation of the move, you can refer to it as a toe-on layout Tkatchev, but understand that it's important for the gymnast to display straight feet as shown in the photo below. Some gymnasts pike down, which involves bending forward at the waist, but it isn't as precise.

What to expect in the uneven bars apparatus final

Medal winners tend to be unpredictable in apparatus finals, so expect emotional moments from unexpected winners.In many cases, top gymnasts have already competed on three days in the qualifiers, the team competition, and the individual all-around competitions, so they start to feel a bit weary in the later stages of the nine-day event.

There is a chance for apparatus specialists, those who specialize only in one or two events, as well as some of the less visible gymnastics nations to shine.Gymnasts have already qualified for Tokyo 2020 on one of the apparatuses at various events and World Cups leading up to the Games.Perhaps their country did not qualify a team to compete.So in the qualifiers, it is all or nothing for them, trying to place among the top eight.One mistake and they're out!

What are the top contenders for the Olympic uneven bars final on Sunday 1 August?

All athletes who make the finals and go through a clean routine and have the difficulty are in a good position to win at this point.

Musafina won't be at the event to make it a threepeat, however two contenders to watch for are Lee - the model from above - and Belgian Nina Derwael, who is the two-time world champion the event from 2018 and most recently from this year's world championships in Stuttgart.

At 5'6" (168cm), Derwael is extremely tall for a gymnast, which has made her extremely innovative on the event over her career.

From Lee, it appears as of the US Classic earlier this month, that she now has the toughest routine in the world, so if she hits well, then she may be in the running in Tokyo.See the results here.Cool, huh?
