Purpose This investigation examined the effect of 6 months high- or low-intensity resistance (REX) on mineral density (BMD) biochemical markers adults aged 60–83 yr. Methods Sixty-two women (68.4 ± yr) were stratified for strength randomly assigned to a control (CON, N = 16), (LEX, 24), high-intensity (HEX, 22) group. Subjects participated...

Our goal was to determine the effects resistance training on circulating IGF-I and two of its major binding proteins, IGFBP-1 IGFBP-3. Additional goals were compare time course hormonal changes with strength effect volume extent changes.Thirty-one men women (mean age = 37 +/- 7 yr) completed a 25-wk, 3 d x wk(-1) program in which they performed single-set (1-SET, N 11), multiple-set (3-SET, or no exercise (Control, 9). Before training, after 13 25 wk blood hormones analyzed assessed as sum...

<h3>Objective</h3> To examine the effect of 6 months high- or low-intensity resistance exercise on aerobic capacity and treadmill time to exhaustion in adults aged 60 83 years. <h3>Methods</h3> Sixty-two men women completed study protocol. Subjects were matched for strength randomly assigned a control (n = 16), (LEX, n 24), high-intensity (HEX, 22) group. trained at either 50% their one repetition maximum (1-RM) 13 repetitions (LEX) 80% 1-RM 8 (HEX) 3 times per week 24 weeks. One set each 12...

Untrained individuals develop muscle soreness and increased serum creatine kinase (CK) activity in the blood after strenuous, unaccustomed exercise. An unpublished observation our laboratory revealed that trained weightlifters also experience considerable exercise, but may not show a dramatic CK response. This study examined responses to strenuous exercise weight-lifters (TR, n = 10) untrained subjects (UTR, 10). Trained had minimum of three years weightlifing experience, regularly performed...

Abstract Objective: To compare exercise‐induced oxidative stress and levels of homocysteine cholesterol in normal‐weight overweight older adults after resistance exercise (RX). Research Methods Procedures: This interventional study was conducted at a wellness center. Forty‐nine (age range, 60 to 72 years) were stratified by BMI (&lt;25 kg/m 2 normal weight, ≥25 overweight/obese) then randomly assigned either control non‐exercise group or an RX group. The completed 6‐month training program....

Randomized, controlled trial.To assess the believability of a novel sham intervention for neurodynamic technique (NDT) in participants with signs and symptoms carpal tunnel syndrome (CTS). Additionally, we wished to potential mechanism NDT (hypoalgesia) compare outcomes related clinical pain upper extremity disability between intervention.Preliminary evidence suggests that is effective treatment CTS. A sham-controlled study lacking from literature could provide insight efficacy NDT, as well...

Aim: Resistance exercise performed at low loads (20–30% of maximal strength) with blood flow restriction (BFR) acutely increases protein synthesis and induces hypertrophy when chronically. We investigated myogenic proteolytic mRNA expression 8 h following an acute bout knee extension exercise. Methods: Fifteen subjects (22.8 ± 3.7 years, eight men seven women) were randomized to two conditions: BFR or control All participants four sets (30, 15, 15 repetitions) 20% strength. Persons in the...

This study examined the changes in synovial fluid levels of cytokines, oxidative stress and viscosity six months after intraarticular hyaluronic acid (HA) treatment adults elderly with knee osteoarthritis (OA).This was a prospective, repeated-measures design which patients OA were administered 1% sodium hyaluronate. Patients (N=28) stratified by age (adults, 50-64 years adults, ≥65 years). Ambulatory pain values self-reported physical activity collected at baseline month six.Knee aspirates...

The purpose of this study was to compare the effects two different resistance exercise protocols on self-reported disability, fear avoidance beliefs, pain catastrophizing, and back symptoms in obese, older adults with low (LBP).

In a pilot randomized clinical trial, participants aged ≥60 years (n = 35) with physical limitations and symptomatic knee osteoarthritis (OA) were to 12 weeks of lower-body low-load resistance training blood-flow restriction (BFR) or moderate-intensity (MIRT) evaluate changes in muscle strength, pain, function. Four exercises performed three times per week volitional fatigue using 20% 60% one repetition maximum (1RM). Study outcomes included extensor gait speed, Short Physical Performance...

This study aimed to compare the efficacy of eccentrically focused resistance exercise (ECC RT) concentrically (CNC on knee osteoarthritis (OA) symptoms and strength.Ninety participants consented. Participants were randomized CNC RT, ECC or a wait-list, no-exercise control group. Four months supervised training was completed using traditional weight machines modified-matched that overloaded eccentric action RT). Main outcomes included one-repetition maximal strength (knee extension, leg...

This current concept, narrative review provides the latest integrated evidence of musculoskeletal injuries involved with trail running and therapeutic strategies to prevent injury promote safe participation. Running activities that comprise any form off-road (trail running, orienteering, short-long distance, different terrain, climate) are relevant this review. Literature searches were conducted 1) identify types mechanisms acute chronic/overuse in runners, 2) prevention techniques most...

Introduction/Purpose: This study compared oxidative stress levels antioxidant capacity in nonobese obese participants acute resistance (RX) aerobic exercise (AX). Methods: Blood samples were collected from 28 (mean = 20.8% body fat) 35.0% pre- immediately post-RX AX. Lipid hydroperoxides (PEROX), malondialdehyde (TBARS)...

This investigation examined the effect of 6 months high‐ or low‐intensity resistance exercise on serum homocysteine and lipoprotein (a) levels in adults aged 60–80 years. Forty‐three men women completed study protocol. Subjects were randomly assigned to a control (n=10), (LEX, n=18), high‐intensity (HEX, n=15) group. performed training at either 50% their one‐repetition maximum for 13 repetitions (LEX) 80% eight (HEX) 3 times per week 24 weeks. The load was increased by 5% when rating...
