I have an idea for a new thread...

they always say that if a shark comes accross you in the water it might eat you. If a croc finds you in the water it will eat you.

It's one of the few animals on earth that actually see humans as prey (if they can see you)

Whereabouts? doing what? sorry for prying..  but that place is heaven on earth. I'm desperate to take the missus there.

It is heaven on earth, and everyone should try get up there at least once in their lives.

 

My wife and I managed a small lodge in the heart of the delta for one of the larger safari companies. It was incredible - for most of the year you could only get to the island by boat. On days we had no guests in camp, we would explore the islands on mokoro, go tiger fishing. Very fond memories. When the kids are out of the house, we plan on going back.

Wow. I knew there were Orca's floating around False Bay. But collapse of shark populations is hectic. Hopefully the whales will not be as badly affected.

Was just about to post the article I just read. Very weird.

That's truly sad. 

I've read a previous article on the topic, that they suspect it's as a result of Chinese boat/trawlers (over) fishing illegally in our waters that affects the young/baby sharks' food availability.

The presence of Orcas are also suspect, as there were quite a few dead sharks that washed up on the shores with their livers removed.

This article also points to over-fishing and corruption, although the killer whales and changing ocean conditions could also be contributing factors

Fallows and his colleagues in South Africa’s shark tourism business think they have the answer. The culprit, they believe, is a long-line fishery that has been targeting smaller species of sharks, including soupfin and smooth-hound sharks, which are a favored prey species of great whites. The South African government has encouraged this poorly regulated fishery and has granted licenses to politically connected boat owners...

So cool !!

 

Love the use of ummmm different alcohols...

You are correct ... 50% of the time ..

if i remember correctly, Sifiso Nhlapo made well over 1,000w on the initial sprint

 

EDIT: Holy FAAARK!!!

 

https://www.researchgate.net/publication/236286198_Velocity_Production_in_Elite_BMX_Riders_A_Field_Based_Study_Using_a_SRM_Power_Meter

 

 

The aim of this study was to analyze the production of velocity in bicycle motocross (BMX) compared to other cycling disciplines. Six elite BMX riders, 5 males and 1 female who competed and trained regularly for a period of 12 yrs ± 2 agreed to take part in this study. Each rider performed 3, 50-m sprint tests and a single 200 m fatigue test. The riders’ peak power, fatigue index, power to weight ratio, and cycling revolution per minute were analyzed using a Schoberer Rad Messtechnik (SRM) BMX power meter. The BMX riders’ peak power and power to weight ratio were all found to be similar to those in other sprint cycling events. Peak power outputs of 1539 ± 148 W and 1030 W were recorded with mean power to weight ratios of 21.29 ± 0.84 Watts/Kilogram and 16.65 Watts/Kilogram. The BMX riders’ power fatigue index was found to be higher than other sprint events as riders fatigued at a greater rate. Mean fatigue index was 61.19 ± 5.97 Watts/Second for the male riders and 53.04 Watts/Second for the female rider. A notable finding of this study was the relationship of cycling cadence (rev•min-1), peak power (Watts) and velocity (mi•h-1). This relationship suggests once a BMX rider achieves peak power their pedaling cadence becomes the major contributory factor to velocity production.

 

Read the rest of the text. Elite BMX riders have the same w/kg output as track sprinters, more or less. Only reason the mean output is lower (actual wattage recorded) is that BMXers on avg are 30kg lighter than trackies.

Chat to you tomorrow while we at work.

So top result was 1,687w and lowest was 1,391w for the men.
