Article Synopsis
  • This study evaluated how personal protective equipment (PPE) and holster positions affect the walking and sprinting abilities and comfort of Brazilian police officers.
  • It involved 20 police officers who were tested under three different conditions: no PPE, PPE with a thigh holster, and PPE with a hip holster.
  • Findings showed that PPE affects stride length and gait speed while increasing discomfort, particularly in the back and knees, highlighting the importance of ergonomic design in PPE for better officer mobility.

Considering that water immersion may acutely reduce blood pressure (BP) and that exercise may elicit positive post-exercise hypotension (PEH) responses, we aimed to analyze the presence of PEH in normotensive individuals and compare its magnitude between two resistance training sessions performed in aquatic or land environments. Ten physically active men (23.2 ± 3.

: To compare the effects of 16 weeks of aerobic training (AT) to 8 weeks of AT followed by 8 weeks of combined training (CT), as well as to a control group (CG), on the functional, cognitive and hemodynamic responses of older women exercising in the aquatic environment. : The study is a three-armed parallel randomized controlled clinical trial. For this, 52 older women were first randomized in an aerobic training (AT; n = 35) or control group (CG; n = 17).

The aim of the present study was to compare the neuromuscular, morphological, and functional responses to a high-velocity resistance training (HVRT) program between three cohorts: middle-aged adults (40-55 years, n = 18), healthy older adults (> 60 years, n = 18), and mobility-limited older adults (n = 8). Participants were tested before and after a 4-week control period and then assigned to a 12-week HVRT intervention. Investigated outcomes included ultrasound-derived muscle thickness and quality, maximal dynamic strength (1RM), maximal voluntary isometric contraction (MVIC), and muscle activation (sEMG), as well as muscle power and functional performance.

Background: The aim of the present study was to investigate the muscular and cardiorespiratory adaptations of two water-based training programs in older women.

Methods: Volunteers were divided between a water-based aerobic training (WBA; N.=13), water-based combined training (WBC; N.

Individuals with obesity are recommended to practice physical activity with reduced weight bearing, such as water-based exercises. However, the magnitude of the vertical ground reaction force (Fz) during these exercises is unknown in this population. This study aimed to verify the magnitude of peak Fz (Fz) in women with obesity during different exercises performed in water and on land and at different intensities.

Background: Down Syndrome (DS) is a genetic condition presenting delay in acquisition of main motor milestones, such as walking. Although studies have been investigating the biomechanical parameters during land walking performed by individual with DS, the literature is scarce regarding kinetic parameters analysis in this population, specially during water walking.

Research Question: This study sought to assess the vertical ground reaction force (Fz) of walking performed in water and on land at different speeds by individuals with DS.

The purpose of this study was to investigate the effects of two water-based aerobic programs on cardiorespiratory and neuromuscular outcomes in older women. Forty-one women (60 to 75 years old) volunteered to participate in the study. Participants were randomized into a water-based continuous (CTG; n = 21; 63.

Article Synopsis
  • The study investigated the effects of water immersion on the perceived weight and biomechanics of pregnant women during exercise in their third trimester.
  • The research involved eleven participants performing three water-based exercises, revealing an average weight reduction of about 82.9% during immersion, with similar vertical ground reaction force measures across exercises.
  • Findings support the safety of aquatic exercises for pregnant women, minimizing injury risks while promoting physical activity.

The neuromuscular adaptations between ergometer-based high-intensity interval training (HIIT-T; n = 15), whole-body high-intensity interval training (HIIT-WB; n = 12) and moderate-intensity continuous training (MICT; n = 14) were compared in forty-one healthy men randomized to 16 weeks of training (3x per week). Two-way repeated measures analysis of variance (ANOVA) showed countermovement (CMJ) and squat (SJ) jump height (HIIT-T: 8.5 ± 13.

This study aimed to investigate the effects of two water-based training programs (aerobic and combined) and a non-periodized physical activity program on functional capacity and quality of life (QoL) of elderly women. Forty-one elderly female volunteers (65 ± 4 years) were divided into three groups: aerobic training group (WBA, n = 13), combined training (sequence: resistance/aerobic; WBC; n = 11) and a control group of non-periodized physical activity program (CG, n = 9). The participants performed the water-based trainings twice a week for 12 weeks.

The purpose of the study was to compare the acute effects of water-based resistance-aerobic (RA) and aerobic-resistance (AR) sequences on systolic blood pressure, diastolic blood pressure (DBP), and mean blood pressure (MBP) in young women. Thirteen active women participated in four sessions: (1) exercises familiarization, (2) aquatic maximal test to determine the heart rate (HR) corresponding to the anaerobic threshold (HR), (3) concurrent protocol RA, and (4) concurrent protocol AR. Both protocols were initiated with the blood pressure measurements at rest in supine position.

The aim of the present study was to compare the peak anterior-posterior (Fy) and medio-lateral (Fx) ground reaction forces (GRFs) of women performing stationary running at different intensities in aquatic and dry land environments. Fourteen young women performed the stationary running exercise at three cadences (first ventilatory threshold, second ventilatory threshold and maximum effort, as determined during exercise in water) in aquatic and dry land environments. Two-way repeated measures ANOVA was used to analyse the data (α = .
