LONDON -- Wearing a fitness tracker may help you keep tabs on how many steps you take, but the devices themselves -- even with the lure of a cash reward -- probably wont improve your health, according to the biggest study yet done on the trendy technology.Scientists say that although the activity trackers may boost the number of steps people take, it probably isnt enough to help them drop pounds or improve overall health.These are basically measuring devices, said Eric Finkelstein, a professor at Duke-NUS Medical School in Singapore, who led the research. Knowing how active you are doesnt translate into getting people to do more and the novelty of having that information wears off pretty quickly.Finkelstein and colleagues tested the Fitbit Zip tracker in a group of 800 adults in Singapore, by dividing them into four groups. Of those people, more than half were overweight and obese and about one third were active.A control group got information about exercise but no tracker and a second group got the Fitbit Zip; everyone in those groups also got about $2.92 a week. Participants in the last two groups got the tracker and about $11 for every week they logged between 50,000 and 70,000 steps. One of the groups had the money donated to charity while the other kept the cash.After six months, people with the Fitbit and who got the cash payment showed the biggest boost in physical activity. But after a year, 90 percent of participants had abandoned the device. The physical activity of the Fitbit wearers did not decline over the year as much as it did for those who were not given a tracker, but the higher activity level wasnt enough to produce any improvements in weight, oxygen capacity, or blood pressure.These trackers can encourage people to take more steps, but it still seems like these random extra steps arent enough to really improve your health, Finkelstein said. He said whats needed is more active steps, or what would amount to brisk walking or more rigorous exercise.The study was paid for by Singapores ministry of health and published online Tuesday in the journal Lancet Diabetes & Endocrinology.The results seem to reinforce those of another study, published last month in the Journal of the American Medical Association. In that study, conducted over two years, researchers found that adding wearable activity tracking devices to a diet and fitness program didnt result in more weight loss. Those who didnt wear devices lost about five pounds more than those who wore them, but both groups slimmed down and improved their eating habits, fitness and activity levels.Fitbit, in a statement responding to the study Tuesday, said: We are confident in the positive results our millions of users have seen from using Fitbit products. The statement went on to say that it was in the process of improving its trackers.Finkelstein said some of the newer fitness trackers have more advanced features, like prompts to exercise and ways to link to social media, but he still thinks it is unlikely people will radically change their exercise regimes without a more comprehensive approach.Some experts said the results were disappointing but not surprising.We should not be so naive to believe that simply by giving a sleek-looking gadget to someone, they will change deeply-rooted lifestyle habits, said Emmanuel Stamatakis, a physical activity expert at the University of Sydney who was not part of the research.Others said the trackers might be more useful if they were aimed specifically at unhealthy people.People who are active are already motivated so they dont need these devices, said Lars Bo Andersen of Norways Sogn and Fjordane University College.Fitbit shares have fallen by half since the beginning of the year, to just under $15 a share.---Medical Writer Lindsey Tanner contributed to this story from Chicago.

Every year there are several mature-age players drafted through the state leagues who offer AFL clubs immediate value and performance.Last year, Marcus Adams (pick 35), Mitch Brown (pick 54), Sam Collins (pick 55), Rupert Wills (pick 63), Sam Menegola (pick 66), Michael Hartley (pick 68), Josh Wagner (rookie draft pick 6), Anthony McDonald-Tipungwuti (rookie draft pick 22), Josh Smith (rookie draft pick 25), Ryan Davis (rookie draft pick 38) and Tom Ruggles (rookie draft pick 44) proved valuable at AFL level. They all showed they had the capacity to play a role and potentially remain long-term players at AFL level.Recruiting state league players in the latter portion of the draft and during the rookie draft consistently represents strong draft day value for clubs. It is an effective way -- if list holes during trade week and free agency have not been adequately addressed -- for clubs to find players who can immediately step into an AFL team and fill that hole.Historically the state leagues prove a fertile recruiting ground for AFL clubs, with general defenders and midfielders most commonly found. Some key defenders and ruckmen can be identified through the state leagues, though the numbers vary from year to year. By contrast key forwards and general forwards are relatively much less frequently identified through the state leagues, with fewer forwards at these levels displaying AFL-standard talent.So, which state league prospects could be drafted this year?The most likely state league player to be selected in this years AFL draft is Coburg rebounding defender Luke Ryan, who may feature as early as the second or third round. Ryan, 20, a 185cm, 82kg rebounding defender has from his 10 games this season made a significant impression and demonstrated clear AFL potential. His intercept marking, composure with ball in hand and kicking from the back half has been a highlight.In the WAFL, making a significant impression and also looming as a likely national draft selection has been Subiacos Liam Ryan. He is a 186cm, 76kg, high flying 20-year-old forward. Ryan has kicked an impressive 40 goals from his 16 WAFL League games while taking several highlight reel-worthy marks throughout the season.Relatively, the greatest scarcity in the state leagues are key forwards. The better key forwards typically have been identified and drafted straight out of the under-18 competitions nationally. This years most advanced plug and play key forward is South Adelaides 27-year-old star goal kicker Brett Eddy. Eddy, 193cm and 92kg, kicked 74 goals from 20 games this season in the SANFL. While he is strong overhead and clean at ground level, Eddy stands out because of his rare ability (regardless of how tightly his direct opponent plays him) to find a way to get goal side of his opponents to kick goals. Eddy has the capacity to offer immediate depth and possibly, depending on the quality of the teams other key forwards, push for a position inside a clubs best 22.Also in the WAFL, Claremont midfielder Jye Bolton has enjoyed a breakout year through the midfield. Last year, Bolton played only 10 games for Werribee in the VFL but with Werribee shifting from a partial alignment with North Melbourne to a full alignment this year, Bolton made the shift to Claremont for greater opportunities. The move has paid off handsomely for Bolton, who won the 2016 Sandover Medal as the competitions best and fairest player. Bolton, a 24-year-old who was rookie listed to Collingwood for one season, is a 183cm, 80kg midfielder who is ready to play at AFL level. He has the capacity to play either as an inside or outside midfielder for a team and has the game to slot into a side seamlessly.Performing strongly and continuing his development this year as a key defender, Tyler Keitel, a 20-year-old, 194cm, 91kg key defender, has taken strong strides forward in his second season playing WAFL League football for West Perth. He has impressed this season intercepting down back and has shown the versatility as required to play in other positions.Firmly in the mix to be selected in the national draft is developing North Ballarat ruckman Rowan Marshall. The 203cm big man, who will turn 21 in November, has shown significant growth in the VFL this season and has shown ability both through the ruck and up forward. His tackling this season has proven particularly impressive along with his mobility and invollvement around the ground.ddddddddddddAnother young ruckman who is also in the mix to be selected is 21-year-old, 204cm, 104kg Claremont ruckman Darcy Cameron. Cameron has taken another step in the right direction this year and has not only proven effective as a tap ruckman but also as a forward with 36 goals and 106 marks from his 19 WAFL League games. He has had another impressive season and may, as a relieving ruckman or No. 1 ruckman, be a developable player.The list of ready-to-go midfielders and general defenders is long.Of the midfielders in the NEAFL this year who are ripe for the picking, Blake Grewar, Jordan Harper, ex-Sun Andrew Boston, James Ives and Hayden Bertoli-Simmonds are among the better performers and all fit into the much desired 20-25 year-old age group where they all are mature enough to contribute now but still young enough to remain with a club medium to long term.From the SANFL, ex-Crow rookie James Battersby, Kaine Stevens, Christopher Jansen and ex-Blue Nicholas Holman are among the more impressive South Australian midfielders. Zane Kirkwood will turn 26 before the start of next season but has been one of the most impactful midfielders in the SANFL in recent seasons and may be worth a look.From the VFL, Sam McLachlan, Michael Gibbons, Tom Atkins and Matt Hanson loom are among the more promising, young VFL-listed midfielders. Robbie Fox as an outside type who can also play back is another name that has been discussed among AFL recruiters. The 187cm, 87kg, 23-year-old is a possible late draft choice.Down back in the NEAFL, ex-Gold Coast rebounding defender Jackson Allen is a damaging player with a long, strong kick and good acceleration. Matthew Sully in a key defence post could also be suitable for AFL play. He a 196cm, 95kg key defender who holds his own in the one-on-one contests and shuts down his direct opponent each week.Down back in the VFL as key defenders who may be third talls at AFL level, Tom Stewart and Brody Mihocek have both had strong seasons and developed well. Collingwoods Jordan Kelly, who was previously AFL-listed by Hawthorn and Western Bulldogs, has made meaningful inroads this year and been a reliable two-way player this season. Also on Collingwoods VFL list and impressing down back has been classy ball user Ryan Pendlebury, who is the younger brother of Scott. Breaking out as a key defender, Declan Keilty has also attracted some AFL interest and is in the mix for selection.In the WAFL, ex-West Coast Eagle Blayne Wilson has again elevated his standard of performance with 163 marks and 449 disposals from his 23 games down back this season. Playing an exciting style brand of footy down back has been Marlion Pickett, who as a linebreaker makes things happen with ball in hand. He is also able to play forward and have an impact. Both Wilson and Pickett will turn 25 before the start of the 2017 season and could each fill a need for a team if selected.As forwards, from the SANFL talented goal sneak Willie Rioli has made meaningful inroads this year and is on the radar of some clubs after losing significant weight and getting in much better shape. Joshua Scott, who was an impressive goal kicker in the TAC Cup a few years ago, has had a strong season. Ex-Carlton rookie Luke Reynolds also has improved significantly this season and has developed into an effective leadup forward who finished the SANFL season with 43 goals, one more than Joshua Scott.In the VFL, small forward Hisham Kerbatieh after being overlooked in last years AFL draft has again put up his hand for selection. Ex-Saint Ahmed Saad led the VFL goalkicking this year and also could fill a role for a team in a front half.Of the other ruckmen, Caseys 22-year-old, 203cm, 100kg Oscar McInerney big man is the third ruckman in the mix and is another genuine draft chance. He moves well and displays impressive cleanness below his knees for someone of his height.While Eddy is the clear standout of the state league key forwards, if a club is looking for someone a few years younger than Eddy, ex-Port Adelaide key forward Mason Shaw looks like the most likely alternative. The 197cm, 94kg Shaw, who will turn 23 before the start of the 2017 season, kicked 51 goals and took 128 marks from his 23 games which is a solid return.
