"IF you look at any race, you'll see a range of bodies: tall, short, big, small, fat, whatever. Those bodies are out there doing their thing, and even if you don't have what's considered a typical 'runner's body', you can do it too." -Mirna Valerio
Talk about some Monday Motivation! Have a great day today and remember that you can take on the world today!
“Our former national team coach Bruno Bini came up with that [nick]name [Le Roc]. I was, and maybe I still am, regarded as a rugged player... But I can tell you I wasn’t all that happy about it at the time. I was a little annoyed about being pigeon-holed as a tough, not to say an aggressive, player. Looking back now, though, I think it’s very flattering. A rock is a very strong symbol and epitomises solidity. In all modesty, I think it kind of suits me. A rock symbolises what I am on the pitch and in my head: I never go to pieces; I never give up.” -Laura Georges
Serena Williams is one of the best and most dominant tennis players of all time. Today I am going to go over a couple of her serve speeds to show how hard of a hitter she is and how consistent she is.
Fastest Service Speed: 128.6 mph/ 207.0 km/h (2013)
2014 Best: 122.4 mph/ 196.98 km/h
2015 Best: 128.0 mph/ 206.0 km/h
Unfortunately, the Internet was being a pain and I could only obtain 3 calculations. Here is how she did for the past three years--not including this past season-- and how close everything is.
Mean: 126.3 mph
Standard Deviation: 3.42 (measures how much each speed is away from the mean speed).
Looks like Serena is doing relatively well at maintaining a hard shot and that is one of the many reasons why she is the best in the world.
How she measured up to everyone else in 2015:
Mean (for all Top 10 in speed, including Williams): 124.43 mph
Standard Deviation: 1.46
To calculate how well she did, I will subtract her performance in 2015 by the mean of everyone and divide it by the Standard Deviation. This standardizes and shows how far apart she really is from the competition.
128-124.43= 2.45 SD's away
Hi, I'm Jenna and I'm a sports fan! I've been avidly watching sports since 2011 because I found that by watching sports, I would be able to communicate with my dad and brother better. Ever since I got into sports, I've been able to enjoy myself more when I go to sporting events with my family.
