Fact check for fitness beyond BMI



Once upon a time, health professionals seemed to be in agreement that body mass index (BMI) was the surest way to measure someone's health. But in recent years, this has been challenged by scientists who suggest that the test is outdated, throws up anomalies and hence should be ignored. We spoke to Tom Woolf, a former professional rugby player and the founder of PTX Performance Training in Dubai, about which system is the truest gauge of one's health.

BMI

What it is A measurement computed by taking one's mass in kilograms and dividing it by the square of one's height in metres. From this, 18.5 is considered underweight, between 18.5 and 24.9 is normal, 25 to 29.9 is overweight and 30 or more is clinically obese.

Pros It's simple to calculate, meaning anyone with a set of scales, a tape measure and calculator can figure it out.

Cons Tom Woolf explains: "Under the system, someone like [the former England rugby union player] Jonny Wilkinson would be deemed clinically obese because of his height to weight ratio and his bone and muscle density. Muscle is a lot denser than fat, so someone who has a lot of muscle can be heavy, even though they're extremely fit, so clearly [BMI] throws up a number of anomalies."

Body composition analysis

What it is Usually conducted with a modern, bioelectronic machine that forces a weak electric current through your body to reveal your fat content, bone density, muscle mass and water levels.

Pros It enables you to work out the exact proportion of various elements in the body, so it's a lot more accurate than BMI. "We use it when people are coming to us to get fitter, rather than just measuring absolute weight or BMI, as we can see exactly how our programmes are affecting them," says Woolf.

Cons "It is prone to a number of anomalies," says Woolf. "Someone like a sumo wrestler or a professional rugby prop forward are big, roly-poly guys with high fat content, but will score very highly in fitness tests, and probably be in the top one percentile globally."

Heart rate

What it is This is measured in one of two ways. First, as a resting heart rate, in which a lower result indicates a much stronger cardiac muscle, hence a better metabolic rate. A rate of between 60 and 90 beats per minute is considered normal, while elite athletes may register between 40 and 60 beats per minute. Second, as recovery, in which your heart's beats per minute are measured for a fixed period (usually one minute) after ceasing activity. The closer it is to one's pre-exercise heart rate, the fitter you are.

Pros "It's a very good indicator of aerobic capacity," says Woolf. "If someone is getting fitter, then both resting heart rate and recovery heart rate should decrease over time."

Cons "We find that it's not always accurate, as different climates can have different results on people. For example, someone who is from a European, cold environment who's not used to the climatic conditions over here would have a faster heart rate," says Woolf.

Waist-to-hip ratio

What it is A fitness measurement that's worked out by dividing the narrowest point of your waist by the widest point of your hips. According to some scientists, a ratio of 0.7 - or a waist measurement that is exactly 70 per cent of the hip circumference - is the ultimate goal for women.

Pros All you need is a tape measure and a calculator. For women, it takes into account that some voluptuous women may still be healthy, even though they have a comparatively high percentage of body fat.

Cons "We wouldn't use this as it's very reliant on genetic factors," says Woolf. "People store fat in different parts of their body, so it can skew the results in different ways. These are good for health practitioners to ascertain whether there will be longer-term risks, but they're not a good indicator of fitness."

VO2 Max test

What it is An analysis to ascertain the maximum amount of oxygen, in millimetres, one can use in a minute per kilogram of body weight. Those with high results can use oxygen more efficiently and thus exercise more intensely than those who are out of shape. Your average, untrained, young person will have a VO2 Max in the 40s, while an elite endurance athlete may record results in the 80s. Measuring VO2 Max accurately requires an all-out effort (usually on a treadmill or bicycle) with special breathing measurement equipment in a sports performance lab.

Pros It's a very scientific indicator of a person's aerobic capacity.

Cons Accurate results require a lab full of expensive equipment. Also, it fails to take into account the subject's strength. "We use this test to measure aerobic capacity," says Woolf, "but we also measure anaerobic capacity and strength. You need to take into account all of these when working out someone's fitness levels."

How tumultuous protests grew
  • A fuel tax protest by French drivers appealed to wider anti-government sentiment
  • Unlike previous French demonstrations there was no trade union or organised movement involved 
  • Demonstrators responded to online petitions and flooded squares to block traffic
  • At its height there were almost 300,000 on the streets in support
  • Named after the high visibility jackets that drivers must keep in cars 
  • Clashes soon turned violent as thousands fought with police at cordons
  • An estimated two dozen people lost eyes and many others were admitted to hospital 
BIOSAFETY LABS SECURITY LEVELS

Biosafety Level 1

The lowest safety level. These labs work with viruses that are minimal risk to humans.

Hand washing is required on entry and exit and potentially infectious material decontaminated with bleach before thrown away.

Must have a lock. Access limited. Lab does not need to be isolated from other buildings.

Used as teaching spaces.

Study microorganisms such as Staphylococcus which causes food poisoning.

Biosafety Level 2

These labs deal with pathogens that can be harmful to people and the environment such as Hepatitis, HIV and salmonella.

Working in Level 2 requires special training in handling pathogenic agents.

Extra safety and security precautions are taken in addition to those at Level 1

Biosafety Level 3

These labs contain material that can be lethal if inhaled. This includes SARS coronavirus, MERS, and yellow fever.

Significant extra precautions are taken with staff given specific immunisations when dealing with certain diseases.

Infectious material is examined in a biological safety cabinet.

Personnel must wear protective gowns that must be discarded or decontaminated after use.

Strict safety and handling procedures are in place. There must be double entrances to the building and they must contain self-closing doors to reduce risk of pathogen aerosols escaping.

Windows must be sealed. Air from must be filtered before it can be recirculated.

Biosafety Level 4

The highest level for biosafety precautions. Scientist work with highly dangerous diseases that have no vaccine or cure.

All material must be decontaminated.

Personnel must wear a positive pressure suit for protection. On leaving the lab this must pass through decontamination shower before they have a personal shower.

Entry is severely restricted to trained and authorised personnel. All entries are recorded.

Entrance must be via airlocks.

Fighter profiles

Gabrieli Pessanha (Brazil)

Reigning Abu Dhabi World Pro champion in the 95kg division, virtually unbeatable in her weight class. Known for her pressure game but also dangerous with her back on the mat.

Nathiely de Jesus, 23, (Brazil)

Two-time World Pro champion renowned for her aggressive game. She is tall and most feared by her opponents for both her triangles and arm-bar attacks.

Thamara Ferreira, 24, (Brazil)

Since her brown belt days, Ferreira has been dominating the 70kg, in both the World Pro and the Grand Slams. With a very aggressive game.

Samantha Cook, 32, (Britain)

One of the biggest talents coming out of Europe in recent times. She is known for a highly technical game and bringing her A game to the table as always.

Kendall Reusing, 22, (USA)

Another young gun ready to explode in the big leagues. The Californian resident is a powerhouse in the -95kg division. Her duels with Pessanha have been highlights in the Grand Slams.

Martina Gramenius, 32, (Sweden)

Already a two-time Grand Slam champion in the current season. Gramenius won golds in the 70kg, in both in Moscow and Tokyo, to earn a spot in the inaugural Queen of Mats.
