Power of lower extremities and age were the main determinants on the agility test for adults in a cohort of men aged 66–91 years
2019
Study Design: Cross-sectional study. Objective: To evaluate the relationship between agility and personal factors, muscle strength and power, mobility, self-reported balance and physical activity among older men. Methods: Agility was measured by using the Agility Test for Adults (ATA). We studied 100 Finnish male former elite athletes (endurance n = 50; power n = 50) and 50 matched controls aged 66 to 91 years (mean age 75.5 years). The associations between agility and other variables were similar between three groups; thus, multiple linear regression analyses were done by using the pooled data of the participants. Results: On the basis of multiple linear regression analyses, combination of…
Exercise programs for subjects with low back disorders.
2007
Exercise has played a central role in rehabilitation of subjects with low back pain. The research in this field has intensified since the 1980s. Low back pain has been associated with both physically stressful and sedentary occupations. There is no clear association between low back pain and physical activity during leisure time. Many studies have shown that subjects with back pain have impairments in muscular and connective tissue, functional limitations in muscular strength, endurance, speed, and neuromuscular functions, and physical, social and psychological disabilities. The ultimate aims of the exercise-based programs are to reduce and prevent these impairments, functional limitations …
Muscle Strength and Physical Performance Are Associated with Reaction Time Performance in Older People
2021
Background: Functional mobility and muscle strength are well known risk factors for sarcopenia. Furthermore, possible associations have been suggested between predisposing factors of sarcopenia and reaction time among the elderly. This study aims to analyze possible associations of functional mobility and muscle strength and reaction times in a population of people aged >
Can Vitamin D deficiency influence muscle perfomance in post-menopausal women? A multicenter retrospective study
2018
Background: The presence of the vitamin D receptor (VDR) has been recently demonstrated in human muscle supporting the theory of a role of vitamin D in the proliferation and differentiation of muscle cells. So far only few studies investigated the association between vitamin D and muscle performance in postmenopausal women. Aim: To define the functional impact of vitamin D deficiency. Design: Multicenter retrospective study. Setting: Five Italian outpatient services of Physical and Rehabilitation Medicine (PRM). Population: Postmenopausal women. Methods: We divided the population in two groups based on the threshold of 30 ng/mL as cut-off to define sufficient and insufficient serum levels o…
Neuromuscular Training Warm-up Prevents Acute Noncontact Lower Extremity Injuries in Children’s Soccer : A Cluster Randomized Controlled Trial
2021
Background: Prevention of sports injuries is essential in youth, as injuries are associated with less future physical activity and thus greater all-cause morbidity. Purpose: To investigate whether a neuromuscular training warm-up operated by team coaches is effective in preventing acute lower extremity (LE) injuries in competitive U11-U14 soccer players. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: Twenty top-level U11 to U14 soccer clubs in Finland were randomized into intervention and control groups and assessed for 20 weeks. Participants included 1403 players (280 female, 1123 male; age range, 9-14 years): 673 players (44 teams) in the intervention group and …
Muscle strength according to level of physical exercise and educational background in middle-aged women in Finland.
1992
The aim of this study was to examine the role of socio-economic status and the practice of physical exercise in explaining variation in muscle strength in 50 to 60-year-old women. Consequently, four study groups combining education and physical activity were formed: (1) university education, physically active; (2) university education, sedentary; (3) vocational or lower level of education, physically active; (4) vocational or lower level of education, sedentary. Maximal isometric strength of hand grip, arm flexion, body flexion and extension as well as dynamic power of the abdominal muscles were measured in 112 women. The results of the maximal isometric strength measurements were standardi…
Lift weights to fight overweight
2014
Although resistance training (RT) has long been accepted as a means for developing and maintaining muscular strength, endurance, power and muscle mass, its beneficial relationship with health factors and chronic disease has only recently been recognized in the scientific literature. Prior to 1990, resistance training was not a part of the recommended guidelines for exercise training and rehabilitation for either the American Heart Association or the American College of Sports Medicine (ACSM). In 1990, the ACSM recognized resistance training as a significant component of a comprehensive fitness programme for healthy adults of all ages, a position subsequently confirmed few years after. At pr…
Physical training considerations for optimizing performance in essential military tasks.
2021
Physically demanding essential military tasks include load carriage, manual material handling and casualty evacuation. This narrative review characterizes the main physical attributes related to performance of these occupational tasks and reviews physical training intervention studies in military settings to improve performance in these military tasks. Load carriage performance requires both aerobic and neuromuscular fitness with greater emphasis on maximal strength and absolute maximal oxygen uptake, especially when carrying heavier loads. In manual material handling, maximal strength and power are strongly associated with discrete lifting, while muscular strength, muscular endurance and a…
Effects of concurrent strength and endurance training in women with early or longstanding rheumatoid arthritis: Comparison with healthy subjects
2003
Objective To investigate the effects of a 21-week concurrent strength and endurance training protocol on physical fitness profile in women with early or longstanding rheumatoid arthritis (RA) compared with healthy subjects. Methods Twenty-three female patients with RA volunteered for the study. Twelve had early RA and eleven had longstanding RA. Twelve healthy women served as controls. Maximal strength of different muscle groups was measured by dynamometers, walking speed with light cells, and vertical squat jump on the force platform to mirror explosive force. Maximal oxygen uptake was measured by gas analyzer. Six training sessions (3 strength training and 3 endurance training) were carri…
Electrophysiological adaptations to endurance and strength training
2020
Abstract Sex differences in exercise training adaptations are still a largely unexplored field of study. There are well-known differences between men and women in terms of their average baseline fitness, such as larger muscle mass and higher cardiorespiratory fitness in men compared to women. Trained women may have a higher performance level than untrained men, but at the top end of the physical training and performance curve, i.e., where athletes are, men exhibit a higher prevalence and amplitude of sinus bradycardia and other electrophysiological changes. This chapter will explore whether men and women respond differently to a standardized training stimulus when sex differences at baselin…
