Progression and perceptual responses to blood flow restriction resistance training among people with multiple sclerosis.

Purpose: Resistance exercise can attenuate muscular impairments associated with multiple sclerosis (MS), and blood flow restriction (BFR) may provide a viable alternative to prescribing heavy training loads. The purpose of this investigation was to examine the progression of upper and lower body low-load (30% of one-repetition maximum [1RM]) resistance training (RT) with BFR applied intermittently during the exercise intervals (RT + BFR) versus volume-matched heavy-load (65% of 1RM) RT.

Methods: Men and women with MS (n = 16) were randomly assigned to low-load RT + BFR (applied intermittently) or heavy-load RT and completed 12 weeks (2 × /week) of RT that consisted of bilateral chest press, seated row, shoulder press, leg press, leg extension, and leg curl exercises.

Sitting Less for Success: Reducing Sedentary Behaviors to Increase Kindergarten Achievement.

Background: Physical activity (PA) improves outcomes, but disadvantaged children typically experience more sedentary behavior (SB). This study explored movement, executive function (EF) health, and academic achievement (AA) for economically disadvantaged kindergarteners.

Methods: Children in 2 classrooms (n = 16; n = 7) wore wrist-based accelerometers to assess PA/SB during the school day.

Direct and Indirect Impacts of Voluntary Pre-Kindergarten on Kindergarten Readiness and Achievement.

Early Childhood Education (ECE) programs provide skills needed for successful kindergarten strides, especially for students from low socioeconomic backgrounds. While Florida's Voluntary Pre-Kindergarten (VPK) program currently serves most four-year-olds, some educators have questioned the program's quality. The purpose of this study was to investigate the direct and indirect effects of Florida's VPK program on kindergarten readiness and academic achievement for students attending the program in one county's VPK (CVPK) when compared to students who did not attend approved VPK programs in this county.

Patterns of responses and time-course of changes in muscle size and strength during low-load blood flow restriction resistance training in women.

Purpose: The purpose of this investigation was to examine the individual and composite patterns of responses and time-course of changes in muscle size, strength, and edema throughout a 4 week low-load blood flow restriction (LLBFR) resistance training intervention.

Methods: Twenty recreationally active women (mean ± SD; 23 ± 3 years) participated in this investigation and were randomly assigned to 4 weeks (3/week) of LLBFR (n = 10) or control (n = 10) group. Resistance training consisted of 75 reciprocal isokinetic forearm flexion-extension muscle actions performed at 30% of peak torque.

Juvenile probation officers' perceptions on youth substance use varies from task-shifting to family-based contingency management.

The majority of justice-involved youth have problems with substance use, but juvenile justice agencies face numerous barriers to providing evidence-based treatments for these youth. Task-shifting is one strategy for increasing access to such treatments. That is, training juvenile probation officers (JPOs) to deliver substance use treatments, such as contingency management (CM) could improve youths' motivation and behavioral outcomes.

Low-load blood flow restriction elicits greater concentric strength than non-blood flow restriction resistance training but similar isometric strength and muscle size.

Purpose: Low-load venous blood flow restriction resistance training (RT + BFR) has been demonstrated to increase muscle strength to a greater degree than low-load non-BFR resistance training (RT) during isotonic training, but no previous investigations have examined RT + BFR versus RT during isokinetic training. The purpose of the present study was to examine the effects of 4 weeks of isokinetic low-load RT + BFR versus low-load RT on indices of muscle strength, muscle size, and neural adaptations.

Methods: Thirty women (mean ± SD; 22 ± 2 years) participated in this investigation and were randomly assigned to 4 weeks of either RT + BFR (n = 10), RT (n = 10), or control (n = 10) group.

Eccentric and concentric blood flow restriction resistance training on indices of delayed onset muscle soreness in untrained women.

Purpose: Unaccustomed exercise can result in delayed onset muscle soreness (DOMS), particularly as a result of the eccentric phase of the muscle contraction. Resistance training combined with venous blood flow restriction (vBFR) may attenuate DOMS, but the available information in this regard is conflicting. Therefore, the purpose of this study was to examine the effects of low-load eccentric vBFR (Ecc-vBFR) and concentric vBFR (Con-vBFR) resistance training on indices of DOMS.

The association between neighborhood factors and physical activity and screen-time among youth with visual impairments.

Background: Youth with visual impairments tend to be at an elevated risk for developing health-related conditions. A thorough understanding of factors associated with health-related behaviors is crucial for the development of effective interventions. Little research has examined the importance of neighborhood factors for physical activity and screen-time behaviors of individuals with visual impairments.

Comparison of the Effects of Stable and Dynamic Furniture on Physical Activity and Learning in Children.

We compared the effects of traditional (stable) and non-traditional (dynamic) school furniture on children's physical activity (PA), energy expenditure (EE), information retention, and math skills. Participants were 12 students (8.3 years, 58 % boys) in grades 1-5.

High-intensity interval training and β-hydroxy-β-methylbutyric free acid improves aerobic power and metabolic thresholds.

Background: Previous research combining Calcium β-hydroxy-β-methylbutyrate (CaHMB) and running high-intensity interval training (HIIT) have shown positive effects on aerobic performance measures. The purpose of this study was to examine the effect of β-hydroxy-β-methylbutyric free acid (HMBFA) and cycle ergometry HIIT on maximal oxygen consumption (VO2peak), ventilatory threshold (VT), respiratory compensation point (RCP) and time to exhaustion (Tmax) in college-aged men and women.

Methods: Thirty-four healthy men and women (Age: 22.

Simplified method of clinical phenotyping for older men and women using established field-based measures.

The purpose of this investigation was to determine body composition classification using field-based testing measurements in healthy elderly men and women. The use of isoperformance curves is presented as a method for this determination. Baseline values from 107 healthy Caucasian men and women, over the age of 65years old, who participated in a separate longitudinal study, were used for this investigation.
