| 3 | Predicting muscular strength using demographics,skeletal dimensions,and body composition measures显示文摘The purpose of this study was to develop an equation to predict strength for seven common resistance training exercises using anthropometric and demographic measures.One-hundred forty-seven healthy adults(74 males,73 females,3512 yr,17410 cm,8819 kg)volunteered to participate.Body composition values(regional/total)and body dimensions were assessed using dual-energy x-ray absorptiometry(DEXA).Subjects underwent the following maximal strength assessments:Leg Press,Chest Press,Leg Curl,Lat Pulldown,Leg Extension,Tri-ceps Pushdown,and Biceps Curl.Multiple linear regression with stepwise removal was used to determine the best model to predict maximal strength for each exercise.Independent predictor variables identified(p<0.05)were height(cm);weight(kg);BMI;age;sex(0=F,1=M);regional lean masses(LM,kg);fat mass(FM,kg);fat free mass(FFM,kg);percent fat(%BF);arm,leg,and trunk lengths(AL,LL,TL;cm);and shoulder width(SW,cm).Analyses were performed with and without regional measures to accommodate scenarios where DEXA is un-available.All models presented were significant(p<0.05,R^(2)=0.68-0.83),with regional models producing the greatest accuracy.Results indicate that maximal strength for individual resistance exercises can be reasonably estimated in adults. | Sean T.Stanelle Stephen F.Crouse Tyler R.Heimdal Steven E.Riechman Alexandra L.Remy Bradley S.Lambert | 2021 | Sports Medicine and Health Science2021,3,1: | 0 |
| 4 | Wearable positive end-expiratory pressure valve improves exercise performance显示文摘We tested a PEEP(4.2 cmH_(2)O)mouthpiece(PMP)on maximal cycling performance in healthy adults.Experiment-1,PMP vs.non-PMP mouthpiece(CON)[n=9(5♂),Age=30±2 yr];Experiment-2,PMP vs.no mouthpiece(NMP)[n=10(7♂),Age=27±1 yr].At timepoint 1 in both experiments(mouthpiece condition randomized)subjects performed graded cycling testing(GXT)(Corival®cycle ergometer)to determine VO_(2peak)(ml*kg*min^(-1)),O2pulse(mlO2*bt^(-1)),GXT endurance time(GXT-T(s)),and VO_(2)(ml*kg*min^(-1))-at-ventilatory-threshold(VO_(2)@VT).At timepoint 272 h later,subjects completed a ventilatory-threshold-endurance-ride[VTER(s)]timed to exhaustion at VO_(2)@VT power(W).One week later at timepoints 3 and 4(time-of-day controlled),subjects repeated testing protocols under the alternate mouthpiece condition.Selected results(paired T-test,p<0.05):Experiment 1 PMP vs.CON,respectively:VO_(2peak)=45.2±2.4 vs.42.4±2.3 p<0.05;VO_(2)@VT=33.7±2.0 vs.32.3±1.6;GXTTTE=521.7±73.4 vs.495.3±72.8(p<0.05);VTER=846.2±166.0 vs.743.1±124.7;O2pulse=24.5±1.4 vs.23.1±1.3(p<0.05).Experiment 2 PMP vs.NMP,respectively:VO_(2peak)=43.3±1.6 vs.41.7±1.6(p<0.05);VO_(2)@VT=31.1±1.2 vs.29.1±1.3(p<0.05);GXT-TTE=511.7±49.6 vs.486.4±49.6(p<0.05);VTER 872.4±134.0 vs.792.9±122.4;O2pulse=24.1±0.9 vs.23.4±0.9(p<0.05).Results demonstrate that the PMP conferred a significant performance benefit to cyclists completing high intensity cycling exercise. | Stephen F.Crouse Jason R.Lytle Sean Boutros William Benton Michael Moreno Patrick C.McCulloch Brad S.Lambert | 2020 | Sports Medicine and Health Science2020,2,3: | 0 |
| 5 | Pelvic region bone density,soft tissue mass,and injury frequency in female professional ballet dancers and soccer athletes显示文摘We recently observed a high prevalence of low pelvic bone mineral density(BMD)in female professional ballet performers.Because this population is susceptible to musculoskeletal overuse injuries,we aimed to determine which regions of the pelvis may be at greatest risk compared to general population females(GENPOP)as well as professional female soccer players(SOCCER,a comparison to other elite athletes regularly subjected to high degrees of loading).Three groups of age-matched females[(GENPOP;n=38,27±1yrs),(BALLET;single com-pany,n=36,26±3yrs),(SOCCER;single NWSL■club,n=34,25±1yrs)]consented to have their BMD and body composition assessed(DEXA,GE■).In addition to soft tissue and total and regional BMD analyses,a segmental analysis of the pelvis was performed to determine site-specific BMD for the iliac fossa,iliac fossa/iliac crest/ilium combined,pubic bone,ischium,and sacrum.A mixed-model ANOVA followed by a Tukey's post-hoc test was used to compare the groups(Type-I error;α=0.05).The BALLET group had lower pelvic BMD for all measures(Avg.%Diff.=15%-27%,p<0.001)compared to the SOCCER group and for the ischium(Avg.%Diff.=8%;p=0.007)and sacrum(Avg.%Diff.=7%;p=0.028)compared to the GENPOP group.The BALLET group had lower lean mass for all measures compared to the other groups(Avg.%Diff.=12%-18%;p<0.01).Professional ballet performers exhibit reduced pelvic region soft tissue and site-specific BMD not previously detected using standard DEXA analyses.These findings highlight which pelvic regions may benefit from preventative strength training and/or nutritional interventions. | Hamed Vahedi Carter M.Taft Joshua R.Daum Sherif Dabash Patrick C.McCulloch Bradley S.Lambert | 2021 | Sports Medicine and Health Science2021,3,3: | 0 |
| 6 | DEXA overestimates bone mineral density in adults with knee replacements显示文摘We examined bone mineral density(BMD)measurements made by dual-energy-xray-absorptiometry(DEXA)taken from 100 patients(♂46/♀54,66±6yr)who previously underwent single total-knee arthroplasty(TKA)to determine if automated software-based artifact detection(ASAD)adequately removes implant artifact from the DXA image before analysis and if potential inaccuracies could be overcome through manual artifact correction(MAC).We also sought to determine if software-based inaccuracies would result in fracture risk misclassification(Low-BMD/Osteopenia=Young-Adult T-Score<−1).Select Results:When using ASAD,limbs with implants had higher BMD(+12.0±1.7%,p<0.001)compared to control limbs resulting in a 2.5±0.2%overestimation of total-body BMD(single implant).Consequently,the prevalence of osteopenia in 95%of patients who would have been observed to have low leg BMD(18/19 patients)and 80%of those found to have low total-body BMD(4/5 patients)would have gone un-diagnosed.This overestimation was eliminated when using MAC.These results reveal a potential issue with ASAD for total-body DEXA scans in TKA patients and highlight the importance of careful review and MAC in those with joint replacements before making diagnostic decisions. | Katharine D.Harper Terry A.Clyburn Stephen J.Incavo Bradley S.Lambert | 2020 | Sports Medicine and Health Science2020,2,4: | 0 |
