Does the addition of single joint exercises to a resistance training program improve changes in performance and anthropometric measures in untrained …

2018

The present study compared changes in muscle performance and anthropometric measures in young men performing resistance training (RT) programs composed of only multi joint (MJ) exercises, or with the addition of single joint (SJ) exercises (MJ+SJ). Twenty untrained men were randomized to MJ or MJ+SJ groups for 8 weeks. Both groups performed the same MJ exercises. The difference was that the MJ+SJ group added SJ exercises for upper and lower limbs. Participants were tested for 10 repetitions maximum (10RM), flexed arm circumference, and biceps and triceps skinfolds. Both groups significantly increased 10RM load for the bench press (MJ 38.5%, MJ+SJ 40.1%), elbow extension (MJ 28.7%, MJ+SJ 31.…

OP0159 THE EFFECT OF HIGH-INTENSITY RESISTANCE TRAINING AND VITAMIN D SUPPLEMENTATION ON MUSCLE STRENGTH IN PATIENTS WITH KNEE OSTEOARTHRITIS: A RAND…

2019

Background Exercise therapy is the cornerstone of knee osteoarthritis (OA) management. In particular muscle strengthening exercise, targeting the characteristic loss of muscle strength present in knee OA, is a key factor for the beneficial effects reported for exercise therapy. The optimal training intensity for resistance training in patients with knee OA, however, is not known to date. Besides resistance training, vitamin D supplementation in patients with vitamin deficiency may optimize muscle strength. Objectives To assess (i) whether high-intensity resistance training leads to greater improvements in muscle strength compared to moderate-intensity resistance training in patients with kn…

Effects of different circuit training protocols on body mass, fat mass and blood parameters in overweight adults

2017

Benefits of exercise are known for a long time, but mechanisms underlying the exercise mode recommendations for specific chronic cardiovascular diseases remain unclear. The aim of this study was to compare the effects of different circuit training protocols in order to determine which is the best for weight loss and for specific overweight- related disorders. Forty-five female sedentary overweight participants from 20 to 50 years (average 31.8±11.2) were enrolled and assigned to three different groups; each group was compared with a control normal-weight group. Three different circuit protocols were randomly assigned to each overweight group: aerobictone- aerobic (ATA), aerobic-circuit-aero…

Do Women and Men over 70 Years Old Similarly Benefit from a One-Year Training Program?

2010

Background and Aims : Exercise capacity declines with age and is improved with exercise training. The aim of this study was to characterize the effects of a one-year combined exercise training in subjects over 70 years old, and to examine the eventual differences obtained between men and women. Methods : After baseline evaluation, 24 subjects (12 men and 12 women) over 70 years old underwent moderate intensity training with aerobic and resistance exercises, 3 hours a week over one year. Workload, oxygen uptake (VO2) and heart rate were measured during a symptom-limited exercise test. The distance walked in 6 minutes (6-MWT) was also registered, and the maximal strength was measured on knee …

Effects of added endurance or strength training on cardiovascular and neuromuscular performance of conscripts during the 8-week basic training period

2010

 The present series of studies investigated changes in Finnish conscripts’ body composition, aerobic fitness and muscle endurance profiles during the last three decades. A second aim was to examine the effects of added endurance (ET) or strength training (ST) on cardiovascular and neuromuscular performance as well as hormonal responses of conscripts during an 8-week basic training (BT) period when compared to the current standardized (NT) programme. The third aim was to study the effects of these three different training programmes on a novel 3K combat running performance test. The present results showed that aerobic fitness and muscle endurance of 20 year old men in Finland has decreased a…

Do Antioxidant Vitamins Prevent Exercise-Induced Muscle Damage? A Systematic Review

2020

Free radicals produced during exercise play a role in modulating cell signaling pathways. High doses of antioxidants may hamper adaptations to exercise training. However, their benefits are unclear. This review aims to examine whether vitamin C (VitC) and/or vitamin E (VitE) supplementation (SUP) prevents exercise-induced muscle damage. The PubMed, Web of Science, Medline, CINAHL, and SPORTDiscus databases were searched, and 21 articles were included. Four studies examined the effects of acute VitC SUP given pre-exercise: in one study, lower CK levels post-exercise was observed; in three, no difference was recorded. In one study, acute VitE SUP reduced CK activity 1 h post-exercise in condi…

Regular Strength and Sprint Training Counteracts Bone Aging: a 10- year Follow-up in Male Masters Athletes

2021

According to cross-sectional and interventional studies, high-intensity strength and impact-type training provide a powerful osteogenic stimulus even in old age. Longitudinal evidence on the ability of high-intensity training to attenuate age-related bone deterioration is currently lacking, however. This follow-up study assessed the role of continued strength and sprint training on bone aging in 40- to 85-year-old male sprinters (n=69) with long-term training background. pQCT-derived bone structural, strength and densitometric parameters of the distal tibia (5% distal-proximal tibia length) and tibial midshaft (50% length) were assessed at baseline and after 10 years. The groups of well-tra…

2020

Purpose: To examine the potential sex differences in adaptations to combined endurance and strength training in recreationally endurance trained (eumenorrheic) women (n = 9) and men (n = 10). Methods: Isometric (ISOMmax) and dynamic bilateral leg press (1RM), countermovement jump (CMJ), running performance (3,000 m time trial), lean mass and body fat % (LEAN and FAT% determined by dual X-ray absorptiometry) as well as serum testosterone and cortisol (TES and COR, respectively, measured using hormone-specific immunoassay kits) were examined before a control period and pre, mid, and post a supervised 10-week combined high-intensity interval endurance training (4 × 4 min intervals and 3 × 3 × …

Effects of strength and endurance training on antioxidant enzyme gene expression and activity in middle-aged men

2007

This study was aimed at investigating the effects of a 21-week period of progressive strength or endurance training on peripheral blood mononuclear cells (PBMC) antioxidant enzyme gene expression and activity in healthy middle-aged untrained men. Strength (n=11) and endurance (n=12) training were performed twice a week, including resistance exercises to activate all the main muscle groups or cycle-ergometer pedaling, respectively. mRNA levels of catalase, glutathione peroxidase (GPx), mitochondrial superoxide dismutase (MnSOD) and cytosolic superoxide dismutase (CuZnSOD) were increased after 21 weeks of strength training, while endurance training induced significant changes only in MnSOD an…

Exploring Moderators of the Effect of High vs. Low-to-Moderate Intensity Exercise on Cardiorespiratory Fitness During Breast Cancer Treatment – Analy…

2022

IntroductionThe results from the physical training and cancer randomized controlled trial (Phys-Can RCT) indicate that high intensity (HI) strength and endurance training during (neo-)adjuvant cancer treatment is more beneficial for cardiorespiratory fitness (CRF, measured as peak oxygen uptake [VO2peak]) than low-to-moderate intensity (LMI) exercise. Adherence to the exercise intervention and demographic or clinical characteristics of patients with breast cancer undergoing adjuvant treatment may moderate the exercise intervention effect on VO2peak. In this study, the objective was to investigate whether baseline values of VO2peak, body mass index (BMI), time spent in moderate- to vigorous-…
