BACKGROUND: This study aimed to evaluate the effects of a combination of aerobic-resistance training (CARET) and broccoli supplementation on dectin-1 levels and insulin resistance in men with type 2 diabetes mellitus (T2D). METHODS: Forty-four males with T2D were randomly allocated to four groups ( = 11 each group): CARET + broccoli supplement (TS), CARET + placebo (TP), control + broccoli supplement (S), and control + placebo (CP). CARET was performed three days per week for 12 weeks. TS and S groups received 10 g of broccoli supplement per day for 12 weeks. All variables were assessed at baseline and 12 …
Fatigue-Induced Sex Differences For Explosive Neuromuscular Characteristics Of The Plantar Flexors, Ben Dalton
Fatigue-Induced Sex Differences For Explosive Neuromuscular Characteristics Of The Plantar Flexors, Ben Dalton
Symposium of Student Scholars
Previous research on fatigue using isometric contractions suggests that females are more fatigue resistant than males, but less is clear regarding fatigue induced by dynamic contractions. PURPOSE: To determine sex differences for explosive voluntary neuromuscular characteristics of the plantar flexors (PFs) during a dynamic fatiguing task. METHODS: Recreationally active males (n=14; 22.4±2.2 yrs) and females (n=15; 20.9±2.5 yrs) performed a fatiguing task of the PFs consisting of 60 maximal isotonic contractions at 30% of their maximal isometric strength using a dynamometer. Peak power (PP), optimal velocity (OV), and optimal torque (OT) were calculated from the first five contractions of the …
Chair Rise Kinetics And Correlates Of Performance In Young And Older Males, Tyler Smith
Chair Rise Kinetics And Correlates Of Performance In Young And Older Males, Tyler Smith
Symposium of Student Scholars
Purpose: To compare chair rise kinetics in young (YM) and older (OM) males, and determine correlates of chair rise performance. METHODS: YM (n=15, age =20.7±2.2 yrs) and OM (n=15, age=71.6±3.9yrs) performed three trials of a single chair rise as quickly as possible on a force plate and the vertical ground reaction force (VGRF) signal was analyzed. Peak VGRF (PF), as well as peak (100 ms rolling average), early (minimum VGRF to 50% PF), late (50% PF to PF), and overall (minimum VGRF to PF) rate of force development (RFD; Δforce/Δtime) were calculated based on phases of the task. Power and …
Age-Related Reduction In High-Velocity Power And Myofiber Morphology And Composition, Ben Dalton
Age-Related Reduction In High-Velocity Power And Myofiber Morphology And Composition, Ben Dalton
Symposium of Student Scholars
Power is diminished more dramatically at higher contraction velocities in older adults. It has been suggested that this may reflect age-related changes in single myofiber morphology or composition. PURPOSE: To examine power, muscle activation, and single myofiber morphology and composition between young (YM) and older (OM) males. METHODS: Power, or torque × velocity, was recorded during isokinetic knee extensions at 60°·s-1 and 180°·s-1 in healthy, untrained YM (n=15; 20.7±2.2 yrs) and OM (n=15; 71.6±3.9 yrs). The relative increase in power from 60°·s-1 to 180°·s-1 was recorded for each participant. Electromyography amplitude of the vastus lateralis (VL) …
Isometric Versus Isotonic Contractions: Sex Differences In The Fatigability And Recovery Of Isometric Strength And High-Velocity Contractile Parameters, Phuong L. Ha, Benjamin E. Dalton, Michaela G. Alesi, Tyler M. Smith, Trisha Vandusseldorp, Yuri Feito, Garrett Hester

The purpose of this study was to investigate potential sex differences in the fatigue- and recovery-induced responses of isometric strength and power, as well as select dynamic contractile parameters after isometric and isotonic plantar flexor (PF) contractions. Healthy males (n = 12; age = 21.8 ± 2.2 years) and females (n = 14; age = 21.4 ± 2.5 years) performed a 2-min maximal voluntary isometric contraction and 120 concentric isotonic (30% peak isometric torque) contractions of the PFs on separate visits. Isometric strength, isotonic power, as well as torque- and velocity-related parameters were recorded before, immediately after, and throughout 10 …
