Effect of Advanced Footwear Technology Spikes on Sprint Acceleration: A Multiple N-of-1 Trial.

Background: In contrast with Advanced Footwear Technology-AFT running shoes for long-distance, little is known about AFT sprint spikes on performance and acceleration parameters. However, their use has become widespread since the Tokyo 2020 Olympics, and knowledge of their effects would seem to be an essential starting point before any clinical or socio-economic considerations.

Objectives: Our objectives were to determine intra- and inter-subject sprinting performance modifications with Nike AFT spikes (NAS) compared to standard spiked-shoes (SS).

Co-construct, implement and evaluate a multi-level intervention to prevent a sedentary lifestyle in children-Study protocol of the CIPRES study.

Background: A sedentary lifestyle is commonly associated with a higher risk of chronic disease development. Among school-aged children from European countries, screen-time represents a significant portion of sedentary time with 39.8% of children spending more than 2h/day in front of a screen on average.

Comparison of dance and aerobic exercise on cognition and neuropsychiatric symptoms in sedentary older adults with cognitive impairment.

Background: To compare the effects of dance and aerobic exercise on cognition and neuropsychiatric symptoms in older people with cognitive impairment.

Methods: Twenty-three older adults (mean age = 78 ± 7 years; males: n = 7, females: n = 16) attending a day care center and diagnosed with cognitive impairment were randomly assigned to a 16-week dance intervention or an aerobic exercise intervention (60 min/week). Cognitive function [Mini-Mental State Examination (MMSE)], neuropsychiatric symptoms [Geriatric Depression Scale-15 (GDS-15), Neuro-Psychiatric Inventory-R (NPI-R)], and physical function [Timed Up and Go (TUG), Activity Daily Living (ADL)] were assessed at baseline and at the end of the intervention.

A systematic review of exercise modalities that reduce pro-inflammatory cytokines in humans and animals' models with mild cognitive impairment or dementia.

Purpose: To investigate which type, frequency, duration, intensity, and volume of chronic exercise might more strongly reduce pro-inflammatory cytokines and enhance anti-inflammatory cytokines in human and animal models with Mild Cognitive Impairment (MCI) or dementia.

Design: A systematic review.

A Comparison of an Alternative Weight-Grading Model Against Chronological Age Group Model for the Grouping of Schoolboy Male Rugby Players.

Objectives: Concerns regarding marked differences in the weights and body composition of young rugby players competing within the same age groups have led to the suggestion of alternative models for grouping young players. The aims of this study were (1) to compare variance in the body size and body composition of schoolboy rugby players (9 to 14 years), across weight- and age-grading models, and (2) to identify morphotypes for the weight model using Hattori's body composition chart.

Materials And Methods: Skinfold thickness measurements were used to assess body fat mass (BF), fat-free mass (FFM), body fat mass index (BFMI), and fat-free mass index (FFMI).
