    Input: The aim of the study was to determine whether a recommendation to walk 10000 steps per day would result in significant improvements in glycemic control , insulin sensitivity , and cardiovascular risk in patients with type 2 diabetes mellitus . The study was a 6-week r and omized controlled trial that included 30 patients with type 2 diabetes mellitus . After 10 days of baseline activity , patients were r and omized into 2 groups : control and active . The control group ( n = 15 ) was instructed to continue with their baseline activity for 6 weeks . The active group ( n = 15 ) was instructed to walk at least 10000 steps per day 5 or more days per week , for 6 weeks .  Data relevant to glycemic control and other parameters of health were collected at study weeks 0 and 6 . There were no differences in the baseline activity between groups ( P = .36 ) . Subjects in the active group significantly increased physical activity by 69 % during the intervention phase of the study ( P = .002 ) , whereas there was no change in the physical activity of the control group ( P > .05 ) . High-density lipoprotein cholesterol and resting energy expenditure significantly increased in the active group ( P < .05 ) . Finally , plasminogen activator inhibitor 1 ( PAI-1 ) activity was reduced by exercise relative to the control group ( P = .03 ) . There were no differences in any other study parameters during the 6-week study . In conclusion , short-term intervention with a pedometer increased physical activity and positively affected plasminogen activator inhibitor 1 activity in previously inactive patients with type 2 diabetes mellitus . The use of a pedometer may prove to be an effective tool for promoting healthy lifestyle changes that include daily physical activity and self-monitoring of therapeutic goals PURPOSE The American College of Sports Medicine and the Centers for Disease Control and Prevention ( ACSM-CDC ) recommend 30 min of daily moderate-intensity physical activity for health ; however , the effectiveness of this recommendation in lowering blood pressure ( BP ) in hypertensives is unclear . The present study tested the hypothesis that walking activity following the ACSM-CDC physical activity recommendation would lower BP in postmenopausal women with high BP . METHODS Resting BP was measured in 24 postmenopausal women with borderline to stage 1 hypertension at baseline , 12 wk , and 24 wk . Fifteen women in the  exercise ( EX ) group walked 3 km.d-1 above their daily lifestyle walking , whereas 9 women in the control ( CON ) group did not change their activity . Walking activity was self-measured with a pedometer in both groups . RESULTS Resting systolic BP was reduced in the EX group after 12 wk by 6 mm Hg ( P < 0.005 ) and was further reduced by 5 mm Hg at the end of 24 wk ( P < 0.005 ) . There was no change in diastolic BP with walking . The CON group experienced no change in BP at either 12 or 24 wk . Body mass was modestly reduced by 1.3 kg in the EX group after 24 wk ( P < 0.05 ) ; however , it was not correlated with the change in BP . There were no changes in selected variables known to impact BP including percent body fat , fasting plasma insulin , or dietary intake . CONCLUSION In conclusion , a 24-wk walking program meeting the ACSM-CDC physical activity recommendation is effective in lowering systolic BP in postmenopausal women with borderline to stage 1 hypertension OBJECTIVE : To conduct a r and omised trial of a physical activity ( PA ) intervention , The First Step Program ( FSP ) for adults with type II diabetes . DESIGN : A 16-week intervention study and 24-week follow-up assessment . PARTICIPANTS : A total of 47 overweight/obese , sedentary individuals ( age=52.7±5.2 y ; BMI = 33.3±5.6 kg/m2 ) recruited through a diabetes education centre . MEASUREMENTS : Primary outcome :  daily PA assessed by pedometer ( steps/day ) . Secondary outcomes : anthropometric measures ( weight , BMI , waist girth , hip girth ) ; indicators of cardiovascular health ( resting heart rate and blood pressure ) ; glycemic control ( fasting glucose , insulin , HbA1c , glucose concentration 120 min postglucose load ) ; plasma lipid status ( total cholesterol , HDL cholesterol , LDL cholesterol , and triglycerides ) . RESULTS : Relative to the CONTROL group , FSP participants increased  their PA > 3000 steps/day ( approximately 30 min/day ) during the intervention ( P<0.0001 ) . Waist and hip girth decreased ( approximately 2–3 cm ) , but did not differ significantly between groups . Significant changes did not emerge for any of the other variables . CONCLUSIONS : The FSP is a practical intervention that elicits an immediate and profound change in walking behaviour . Such change is an important ‘ first step ’ towards increasing the volume and /or intensity of PA necessary to improve long-term health outcomes in this largely sedentary and overweight or obese population . Relapse by 24 weeks indicates that other strategies such as booster sessions are needed to maintain lifestyle change . Further research must determine realistic and responsive health outcomes for this population that are achievable through practical , real-world programming BACKGROUND It is currently unclear how physical activity and diet interact within the ranges of activity seen in the general population . This study aim ed to establish whether a small , acute , increase in physical activity would lead to compensatory change in energy intake and nutrient balance , and to provide power analysis data for future research in this field . METHOD Twelve participants were studied over 7 days of habitual activity and 2 weeks after instruction to increase physical activity by 2000 steps per day . Physical activity was assessed using a diary , the ' activPAL ' activity monitor and a pedometer . Dietary analyses from prospect i ve food diaries were compared between the first and third weeks . RESULTS Participants increased step-counts ( + 2600 steps per day , P = 0.008 ) and estimated energy expenditure ( + 300 - 1000 kJ day(-1 ) , P = 0.002 ) but did not significantly change their energy intake , dietary composition or number of meals per day . From reverse power analysis 38 participants would be needed to exclude a change in energy intake of 400 kJ day(-1 ) with 90 % power at P < 0.05 ; 400 kJ day(-1 ) would compensate for a 2000 steps per day increase in physical activity . CONCLUSION These results did not demonstrate any compensatory increase in food consumption when physical activity was increased by walking an average of 2600 additional steps per day . Power analysis indicates that a larger study ( n = 38 ) will be necessary to exclude such an effect with confidence PURPOSE This study examined the effects of walking speed on the accuracy and reliability of 10 pedometers : Yamasa Skeletone ( SK ) , Sportline 330 ( SL330 ) and 345 ( SL345 ) , Omron ( OM ) , Yamax Digiwalker SW-701 ( DW ) , Kenz Lifecorder ( KZ ) , New Lifestyles 2000 ( NL ) , Oregon Scientific ( OR ) , Freestyle Pacer Pro ( FR ) , and Walk4Life LS 2525 ( WL ) . METHODS Ten subjects ( 33 + /- 12 yr ) walked on a treadmill at various speeds ( 54 , 67 , 80 , 94 , and 107 m x min-1 ) for 5-min stages . Simultaneously , an investigator determined  steps by a h and counter and  energy expenditure  ( kcal ) by indirect calorimetry . Each br and was measured on the right and left sides . RESULTS Correlation coefficients between right and left sides exceeded 0.81 for all pedometers except OR ( 0.76 ) and SL345 ( 0.57 ) . Most pedometers underestimated steps at 54 m x min-1 , but accuracy for step counting improved at faster speeds . At 80 m x min-1 and above , six models ( SK , OM , DW , KZ , NL , and WL ) gave mean values that were within + /- 1 % of actual steps . Six pedometers displayed the distance traveled . Most of them estimated mean distance to within + /- 10 % at 80 m x min-1 but overestimated distance at slower speeds and underestimated distance at faster speeds . Eight pedometers displayed kilocalories , but except for KZ and NL , it is unclear whether this should reflect net or gross kilocalories . If one assumes they display net kilocalories , the general trend was an overestimation of kilocalories at every speed . If one assumes they display gross kilocalorie , then seven of the eight pedometers were accurate to within + /-30 % at all speeds . CONCLUSION In general , pedometers are most accurate for assessing steps , less accurate for assessing distance , and even less accurate for assessing kilocalories OBJECTIVES To determine whether a home-based pedometer-driven walking program with arthritis self-management education ( Walk + ) would increase physical activity , muscle strength , and functional performance in older adults with osteoarthritis ( OA ) of the knee as opposed to arthritis self-management education alone ( EDU ) . DESIGN A r and omized two-by-three ( group-by-time ) design with participants assigned to  Walk + ( n = 17 , mean age + /- st and ard deviation = 69.6 + /- 6.7 ) or EDU ( n = 17 , age = 70.8 + /- 4.7 ) . SETTING Community located in the Baltimore-Washington area . PARTICIPANTS Thirty-four community-dwelling adults , aged 60 and older with symptomatic knee OA and self-reported functional impairment . INTERVENTIONS Both groups received 12 hours of the Arthritis Self-Management program over 12 weeks and were followed for an additional 12 weeks . In addition , the Walk + group received individualized instruction in the use of a pedometer , with the goal of increasing their step count by 30 % of their baseline step count . MEASUREMENTS The outcome measures were physical activity ( daily step counts and total activity vector magnitude as measured by a pedometer and Tritrac-R3D accelerometer ) , quadriceps femoris strength ( isometric peak torque ) , and functional performance tasks ( 100-foot walk-turn-walk , timed stair climb , timed chair rise , and pain status ) . RESULTS Daily steps walked showed a significant group-by-time interaction ( P = .04 ) after controlling for age . From baseline to completion of training , a 23 % increase in daily steps occurred in the Walk + group and a 15 % decrease in the EDU group . Although steps increased in the Walk + group , total activity vector magnitude was maintained , suggesting a more efficient gait . The Walk + group became quicker than the EDU group in the normal-pace walk-turn-walk ( P = .04 ) . An isometric strength gain of 21 % postintervention was seen in the Walk + group , compared with a loss of 3.5 % in the EDU group . CONCLUSION In older adults with symptomatic knee OA , Walk + appears to increase walking , with improvements in muscle strength and walking performance . The use of a home-based pedometer-driven program to increase physical activity , strength , and function in this population warrants further research Izawa KP , Watanabe S , Omiya K , Hirano Y , Oka K , Osada N , Iijima S : Effect of the self-monitoring approach on exercise maintenance during cardiac rehabilitation : A r and omized , controlled trial . Am J Phys Med Rehabil 2005;84:313–321 . Objective : To evaluate the effect of the self-monitoring approach ( SMA ) on self-efficacy for physical activity ( SEPA ) , exercise maintenance , and objective physical activity level over a 6-mo period after a supervised 6-mo cardiac rehabilitation ( CR ) program . Design : We conducted a r and omized , controlled trial with 45 myocardial infa rct ion patients ( 38 men , seven women ; mean age , 64.2 yrs ) recruited after completion of an acute-phase , exercise-based CR program .  Patients were r and omly assigned to an SMA group ( n = 24 ) or control group ( n = 21 ) . Along with CR , the subjects in the SMA group self-monitored their weight and physical activity for 6 mos . The SMA used in this study was based on B and ura ’s self-efficacy theory and was design ed to enhance confidence for exercise maintenance . The control group participated in CR only . All patients were evaluated with the SEPA assessment tool . Exercise maintenance , SEPA scores , and objective physical activity ( average steps per week ) as a caloric expenditure were assessed at baseline and during a 6-mo period after the supervised CR program . Results : Mean period from myocardial infa rct ion onset did not differ significantly between the SMA and control groups ( 12.1 ± 1.3 vs. 12.2 ± 1.2 mos , P = 0.692 ) . All patients maintained their exercise routine in the SMA group . Mean SEPA score ( 90.5 vs. 72.7 points , P < 0.001 ) and mean objective physical activity ( 10,458.7 vs. 6922.5 steps/wk , P < 0.001 ) at 12 mos after myocardial infa rct ion onset were significantly higher in the SMA than control group . SEPA showed significant positive correlation with objective physical activity ( r = 0.642 ,
