Objective: To examine the effects of fatigue on landing biomechanics in single-leg drop landings. Design: Quasi-experimental. Setting: Controlled research laboratory. Participants: Twenty-four healthy individuals (12 women and 12 men). Interventions: Participants performed 3 landings from a height 0.36 m before after fatiguing protocol. Main Outcome Measures: Sagittal ankle flexion, sagittal knee frontal valgus angles (degrees) at initial ground contact; vertical reaction forces (N); time to...
Context: Noncontact anterior cruciate ligament injury has been reported to occur during the later stages of a game when fatigue is most likely present. Few researchers have focused on progressive changes in lower extremity biomechanics that throughout fatiguing. Objective: To evaluate effects sequential protocol sidestep-cutting task (SS). Design: Controlled laboratory study. Setting: Laboratory. Patients or Other Participants: Eighteen uninjured female collegiate soccer players (age = 19.2...
Purpose: Female dancers have lower anterior cruciate ligament (ACL) injury rates compared with physically active women. Enhanced balance can decrease musculoskeletal risk. Dancers are proposed to superior nondancers, and this may reduce their risk for ACL injury. However, whether female actually better than nondancers is unclear. Method: Thirty-three women (15 dancers, 18 nondancers) performed the Balance Error Scoring System (BESS; error scores), Star Excursion Test (SEBT; percent leg...
Dancers experience a high incidence of injury due to the extreme physical demands dancing. The majority dance injuries are chronic in nature and occur lower extremities low back. Researchers have indicated decreased core stability (CS) as risk factor for these injuries. Although CS is suggested negatively affect extremity joint motion lumbar control during activity, this relationship has not been extensively discussed previous literature. Understanding between important help reduce improve...
Ambegaonkar, JP, Shultz, SJ, and Perrin, DH. A subsequent movement alters lower extremity muscle activity kinetics in drop jumps vs. landings. J Strength Cond Res 25(10): 2781–2788, 2011—Drop landings are common training exercises injury research model tasks. Drop have a single landing, whereas include jump after initial landing. With the expected ground impact, instant landing surface suggested to modulate neuromechanics, activity, should be same both tasks when from height onto surface....
Bioimpedance analysis (BIA) has been demanded for the assessment of appendicular skeletal muscle mass (ASM) in clinical and epidemiological settings. This study aimed to validate BIA equations predicting ASM standing supine positions; externally cross-validate new published built-in group individual predictive accuracy; assess overall agreement between measured predicted index as sarcopenia diagnosis. In total, 199 healthy older adults completed measurements multifrequency (InBody770...
Jones, MT, Ambegaonkar, JP, Nindl, BC, Smith, JA, and Headley, SA. Effects of unilateral bilateral lower-body heavy resistance exercise on muscle activity testosterone responses. J Strength Cond Res 26(4): 1094–1100, 2012—Unilateral exercises (HREs) are used for strength training. Little research has examined whether activation (TES) responses differ between these exercises. Our purpose was to compare the effects HRE using surface electromyography (sEMG) TES concentrations. Ten...
Anterior cruciate ligament (ACL) injuries often occur during landing, with female athletes at higher injury risk than male athletes. Interestingly, dancers have lower ACL rates do in general.Female will earlier and greater extremity muscle activity sagittal knee joint leg stiffness basketball players.Cross-sectional group comparison.Fifty-five healthy (35 dancers, 20 players) performed 5 double-leg drop jumps from a 45-cm box. Surface electromyography (onsets amplitudes; prelanding...
Ground reaction force (GRF) and tibiofemoral magnitudes directions have been shown to affect anterior cruciate ligament loading during landing. However, the kinematic kinetic factors modifying these 2 forces landing are unknown.To clarify intersegmental links underlying alteration of GRF vectors secondary changes in sagittal-plane body position single-legged landing.Crossover study.Laboratory.Twenty recreationally active participants (age = 23.4 ± 3.6 years, height 171.0 9.4 cm, mass 73.3...
As the world population ages, practitioners use community-engaged interventions to help older adults stay healthy. Engaging in arts programs (e.g., dance or music) reportedly improves physical and mental health, but little research exists examining these effects community-dwelling adults. Our purposes were examine how taking part 10-week, twice per week community (dance control (social conversation) affected health their perceptions after program participation.<br/> Methods: In this...
Concussions are a public health concern and concussion management in school requires team approach. We examined schoolteachers' administrators' perceptions of concussions, management, implementation return-to-learn (RTL) guidelines.We audio-recorded transcribed semistructured interviews with teachers (N = 16) administrators 6) from system. analyzed data using an analytic induction constant comparison approach.Two themes emerged: different understanding, context. Participants no sport...
The purpose of this study was to compare lower extremity (LE) biomechanics and muscle activity between ‘new’ ‘dead’ pointe shoes in professional female ballet dancers performing relevé arabesque. We compared sway area, peak ankle moments, tibialis anterior medial gastrocnemius activation amplitudes. Nine participated (age = 22.2 ± 2.2 years, height 163.2 6.3 cm, body mass 50.8 6.5 kg) executed three trials arabesque on under two conditions: (108–144 training hours) (3–36 hours). While...
Although data exist on injuries in youth football leagues, there are limited recent injury incidence middle school football. Updated estimates can help drive the development of prevention strategies.Describe epidemiology during years 2015-2016 to 2017-2018.Descriptive study.Data originated from 9 public schools Virginia 2017-2018. Certified athletic trainers collected and athlete-exposure (AE) school-sanctioned games practices boys', Injury counts rates per 1000 AEs were calculated. rate...
Ankle stabilizers can reduce ankle sprain incidence and severity by limiting range of motion. Still whether using them affects performance remains unclear. The authors compared effects 3 stabilizers, tape, lace-up (Swede-O Lok), semirigid (Air-Cast Air-Stirrup) braces, a nonsupport control on vertical jump (Sargent Jump Test), agility (Right-Boomerang Run test), dynamic balance (Modified Bass Test) in 10 volunteers (4 males, 6 females; 25.6 ± 2.8 years, 167.8 13.7 cm, 61.4 10.7 kg)...
Postural deviations can predispose an individual to increased injury risk. Specifically, lumbar are related low back pain and injury. Dancers gymnasts anecdotally suggested have exaggerated lordosis subsequently may be at risk of pathologies. Our objective was examine levels in dancers gymnasts.We examined 47 healthy collegiate females (17 dancers, 29 gymnasts; mean age 20.2 ± 1.6 yrs) using 2-dimensional sagittal plane photographs the Watson MacDonncha Posture Analysis instrument....
Dancers have unique health issues, including high injury rates and functional, nutritional, psychological concerns. Thererfore, developing dancers with literacy is crucial. This study examines 1. the types of health-related information offered in university dance programs, 2. perceptions stakeholders (administrators, faculty, students) toward education provided to these programs. Participating (N = 104) from 11 countries completed a web-based survey examining offerings for students at their...
