Female Triad: Bone recovery after female athlete triad
Women whose bone development is interrupted in adolescence by the so-called ‘female athlete triad’ of disordered eating, delayed menstruation and osteoporosis can still catch up on bone growth well into their twenties.

Female Boxing Injuries: Female boxing safer than expected
Female boxing is no more dangerous than any other female impact sports. That is the encouraging conclusion of a new survey from Italy, where female boxing has been permitted since 2001 but is still regarded as ‘an experimental sport’ (‘Medical survey of female boxing in Italy in 2002-2003’, Br J Sports Med 2005;39:532-536).
The survey of all female boxing competitions in Italy between January 2002 and October 2003 was made up of two elements:

Arm Strength: Transfer of arm strength works one way only
The transfer of strength from a trained limb to an untrained one is a well-known phenomenon, thought to be due to neural adaptations, and offers potential benefits for athletes seeking to maintain strength in an injured limb while it is out of action. But does this apparently miraculous transfer of strength affect both sides equally? Probably not, according to a team of Canadian researchers, who studied transfer of arm strength in right-handed people and found it operated only from right to left – ie from the dominant to the non-dominant side.

Stitch Pain: New light on stitch
A new Australian study offers valuable insights into the common but potentially disabling sport-related condition known colloquially as ‘stitch’ (‘Epidemiology of exercise-related transient abdominal pain at the Sydney City to Surf community run’, J Sci Med Sport 2005; 8:2:152-162).
In a previous study – the largest published on the subject – the researchers found that 60% of runners had experienced exercise-related transient abdominal pain (ETAP) while running within the past year, but this was a retrospective study based on recall.

Record-breaking preditcions : What are the absolute limits to human performance levels?
Everything’s up to date in Kansas City – they’ve gone about as far as they can go!
The song in question, in a musical set in the 1890s, was actually written a hundred years later; the irony lay in the hindsight. In each generation over the last century we have seen new records set, with performances once regarded as superhuman becoming routine and unremarkable, writes Bruce Tulloh.

Sports Injury Pain : Pain and brain – a revolutionary approach to chronic injury
Injury and pain are a competitive athlete’s worst nightmare, scuppering even the best-laid training plans. And when injuries become chronic, they can destroy confidence and even end athletic careers. But a revolution is taking place in our understanding of pain, which has profound implications for the treatment and rehabilitation of many chronic injuries. As Stephen Robson and Louis Gifford explain in the first of a two-part series, it’s time to throw away many of our existing preconceptions about pain and injury.
At a glance:

Creatine: is it really safe for long-term use?
Creatine is the number one choice of sports supplement for athletes at all levels – and with good reason. Unlike most products that compete for space on the shelves of health food stores up and down the country, creatine does precisely what it says on the tin: namely boost the body’s phosphocreatine energy system, thereby enhancing short-term, high intensity anaerobic efforts. But, while there are few, if any, remaining concerns about short-term use, there are still no guarantees of long-term safety, writes Andrew Hamilton.

Pregnancy Weight Training: Pregnancy, strength and fitness
The theory that pregnancy, being a form of graduated weight training, actually improves subsequent performance in women has been dealt a blow by a major new US study suggesting that both fitness and strength decline significantly during pregnancy and are still not fully restored six months after birth.

Caffeine dehydration : Caffeine and alcohol – just how dehydrating are they?
Do you do drugs? Think long and hard before you answer, because the answer is, very probably, yes! Like it or not, alcohol and caffeine are drugs that most of us consume regularly as part of our diet. Like all drugs, they have side effects, one of which is common to both – a ‘diuretic’ (waterloss) effect. But how strong is this effect, and is a diet containing these drugs detrimental to the goal of optimum hydration?

Growing Pains
‘Diseases or complaints of growth’ were first described by Duchamp (1) in his treatise ‘Maladies de la Croissance’ in 1832. These aches and pains were initially thought to be manifestations of rheumatic fever requiring prolonged bed rest, a notion that gave way to the ‘fatigue theory’ proposed by Bennie in 1894 (2). This declared that ‘little legs have performed an unusual amount of work during the day’ and may therefore hurt at the end of the day.

The glycaemic index: how athletes can make it work for them
Unless you’ve been living on Mars for the last 15 years, you’ll already be aware that carbohydrate nutrition is just about the most important weapon in your nutritional toolbox for maximising sport performance. In recent years, the ‘glycaemic index’ – the rate of carbohydrate energy release – has become an important consideration for athletes seeking to consume the ‘right’ type of carbohydrate for a particular mode of training or recovery. But why is this index important and how can you use it to plan your carbohydrate intake?

Sports drinks and teeth
There is no doubt that properly formulated fluid and/or carbohydrate drinks can enhance sports performance. However, more recent research has discovered that regular sports drinks users may be putting their dental health at risk; in particular the protective tooth enamel has been found to erode 30 times faster with regular usage of sports drinks (which tend to be quite acidic) by comparison with plain water!

Vibration Platform: New training aids Good vibrations?
Move over, wobble board – the vibration platform is here. In the past 10 years there has been an increasing interest in the somewhat strange concept of vibration training and its potentially positive impact on athletic performance. Can simply standing on a vibrating platform improve one’s strength, power and flexibility? Is this a gimmick providing a short-term fix, or can athletes and coaches expect to see some valuable long-term training adaptations? Is vibration a useful rehab tool? Here’s the balance of research to date.

Maltodextrin-plus-fructose Drink: Carb combo drink produces most energy
UK researchers have found that ingesting large amounts of two simple carbohydrates during prolonged cycling exercise allows for significantly greater conversion of carbohydrate to energy than ingesting one alone.
A drink containing maltodextrin and fructose, providing the same amount of energy as the first drink;

Cyclists Warm Up
A new UK study has shown that cycling performance is boosted by prior moderate and heavy exercise, but not by sprint exercise.
The researchers set out to determine the effects of three different warm-up regimes on cycling work output during a seven- minute performance trial. Although it is widely accepted that prior warm-up exercise should be performed before the main bout of sporting or exercise activity, previous studies have tended to focus on the physiological effects of warm-up rather than on its potential performance benefit.

Pre-competition exercise: does timing matter?
Cycling time triallists gain a significant performance advantage if, on the day before competition, they train at exactly the same time as the competition is scheduled to start. That is the important conclusion of a new study from the UK.
Eight male recreational cyclists completed two separate 16.1k time trials on cycle ergometers at 7am. On the day before one of the trials, they performed a submaximal workout at 60% VO2max for 30 minutes at 7am; on the day before the other, they performed exactly the same workout at 12 noon.

ACL surgery
The anterior cruciate ligament (ACL) is an intra-articular knee ligament. It is made up of two bundles of fibrous tissue, each 3.5cm long, which act to maintain anatomical relations between the femur and tibia throughout the range of knee motion.

Sports drinks or water : what is the best choice for sports performers?
What does the term sports nutrition conjure up in your mind? Carbohydrate and protein? Vitamins and minerals? Or maybe the more exotic ergogenic aids like creatine? Whatever springs to mind, I bet it isn’t water. Yet water is of supreme, overriding importance to both your health and performance.

Antioxidant Diets: Low antioxidant diets may hamper fuel delivery
Although the jury’s still out on the pros and cons of antioxidant supplementation for athletes, a consensus of scientific opinion is beginning to form around the notion that low antioxidant intakes are undesirable for various reasons.

Speed Training Workouts : Is over-speed training over-hyped?
The goal of over-speed training is to allow an athlete to move his or her limbs faster by using special training techniques to increase limb speed such as hill descents or assisted propulsion from elasticated bungee cords. However, there’s confusion about just how effective over-speed training is and how best to implement it for maximum benefit, as John Shepherd explains.

Blood Doping: New warning on blood doping
Most blood doping techniques can be reliably detected by current anti-doping strategies. But Italian researchers have issued a warning about an alternative and dangerous technique, which is not yet banned and is virtually undetectable by anti-doping tests.

Performance Enhancing Drugs
Can the governing bodies of sport ever win their hard-fought campaign to stamp out the illegal use of performance enhancing drugs? Or are they condemned to stand Canute-like on the shore in a fruitless attempt to resist the onslaught of smarter and ever-less-detectable substances?

Muscle Cramps : No link between hydration and cramps
The popular theory that exercise-induced muscle cramping (EAMC) is caused by fluid imbalances, particularly dehydration and abnormalities in blood electrolyte levels, has been overturned by a South African study of ultra-distance runners.
