Effects of an eight-week high-speed resistance training program on rate of torq...
Duarte Martins, Alexandre; Paulo Brito, Joao; Batalha, Nuno; Oliveira, Rafael; Gonçalves, Bruno; Fernandes, OrlandoBackground: The aging process frequently entails a reduction in muscle strength, attributed to factors such as neural changes resulting in decreased voluntary muscle activation (1). Despite these challenges, it is crucial to implement strategies aimed at enhancing or, at the very least, mitigating these declines associated with aging. Purpose: This study assessed the impact of an eight-week high-speed resistanc...
Effects of a 16-week high-speed resistance training program on isokinetic muscl...
Duarte Martins, Alexandre; Batalha, Nuno; Fernandes, Orlando; Gonçalves, Bruno; Oliveira, Rafael; Paulo Brito, JoaoObjectives: This study investigated the effects of a 16-week high-speed resistance training program on isokinetic muscle strength parameters. Methods: Seventy-nine independent older adults, who were divided into an intervention group (IG, N=40, age: 68.5 ± 3.5 years) and a control group (CG, N=39, age: 72.1±5.9 years) participated in the study. The program lasted 16 weeks, with three sessions per week with 50–6...
Effects of a 16-week high-speed resistance training program on cellular health ...
Duarte Martins, Alexandre; Batalha, Nuno; Paulo Brito, Joao; Oliveira, Rafael; Gonçalves, Bruno; Fernandes, OrlandoObjective: Aging process includes body composition changes, such as an increase in fat mass and a decrease in fat-free mass. Exercise training programs are considered effective strategies to mitigate or prevent those body composition changes. Therefore, this study analysed the effects of a 16-week High-Speed Resistance Training (HSRT) program on body composition parameters in older adults. Methodology: This non...
Effects of a 16-week high-speed resistance training program on the rate of torq...
Duarte Martins, Alexandre; Paulo Brito, Joao; Fernandes, Orlando; Oliveira, Rafael; Marcos-Pardo, Pablo Jorge; Batalha, NunoIntroduction: Aging is often associated with a decline in muscle strength, driven by factors such as neural alterations leading to reduced voluntary muscle activation (Manini & Clark, 2012). These changes negatively impact physical performance and increase the risk of functional limitations in older adults. Objectives: This study aimed to evaluate the effects of a 16-week High-Speed Resistance Training (HSRT) p...
Effects of an eight-weeks high-speed resistance training program on heart rate ...
Duarte Martins, Alexandre; Fernandes, Orlando; Paulo Brito, Joao; Batalha, NunoObjective: This study examined the effects of an eight-week high-speed resistance training (HSRT) program on heart rate variability (HRV) indices (time and frequency domain). Methods: This study included thirty-nine physically independent older adults (age, 68.50±3.52y; BMI, 27.88±4.37 kg/m2). The HSRT program lasted eight weeks, with three sessions per week with 50–60min, each session being comprised of five-s...
Phase angle is related with physical function in older adults: a cross sectiona...
Duarte Martins, Alexandre; Paulo Brito, João; Batalha, Nuno; Oliveira, Rafael; Bilro, Vitor; Fernandes, OrlandoThis study aimed to verify a relationship between phase angle (PhA) with physical function in older adults. We also intend to analyse the ability of PhA to predict physical function after adjusting for poten-tial confounders. This cross-sectional study included fifty-six physically independent older adults (age, 70.57 ± 3.79 years; BMI, 28.09 ± 4.37 kg/m2). Bioelectrical impedance analysis was used to measure P...

Duarte Martins, Alexandre; Batalha, Nuno; Paulo Brito, Joao; Raimundo, Armando; Fernandes, OrlandoObjective: This study examined the effects of an eight-week high-speed resistance training (HSRT) program on physical function, through the handgrip test and three functional fitness tests. Methods: This study included twenty-three physically independent older adults (age, 69.17 ±4 .53 years; BMI, 28.10±4.66 kg/m²). The HSRT program lasted eight weeks, with three sessions per week with 50–60min, each session be...
Phase angle can predict bone indicators in older adults: a cross-sectional study
Duarte Martins, Alexandre; Fernandes, Orlando; Batalha, Nuno; Paulo Brito, JoaoOsteoporosis is considered a worldwide public health concern, which is characterized by low bone mass and microarchitectural changes in the bone being a risk factor for fractures in older adults. This study aimed to verify a relationship between phase angle (PhA) with bone indicators. We also intended to analyse the ability of PhA to predict bone indicators after adjusting for potential confounders. This cross-...
Phase angle can predict muscle strength in older adults: a cross-sectional study
Duarte Martins, Alexandre; Paulo Brito, Joao; Fernandes, Orlando; Batalha, NunoMuscle function is becoming increasingly vital in aging due to increased life expectancy. This study aimed to verify a relationship between phase angle (PhA) with muscle strength. We also intend to analyse the ability of PhA to predict muscle strength after adjusting for potential confounders. This cross-sectional study included fifty-six physically independent older adults (age, 70.57 ± 3.79 years; BMI, 28.09 ...
Effects of a sixteen-weeks high-speed resistance training program on bone miner...
Duarte Martins, Alexandre; Batalha, Nuno; Fernandes, Orlando; Bilro, Vitor; Raimundo, Armando; Paulo Brito, JoaoIntroduction The United Nations estimates 1.5 billion people aged over 65 years in 2025, compared with 703 million in 2019 (1). Unfortunately, the aging process involves the development of many chronic diseases, namely osteoporosis. Osteoporosis is characterized by low bone mass and microarchitectural deterioration of bone tissue (2). Reduced bone mineral density (BMD) and bone mineral content (BMC) with age in...
