Two experiments investigated the relationship between perceptual experience (during practice) and posttest improvements in perceptual accuracy and consistency. Experiment 1 investigated the potential relationship between how often knowledge of results (KR) is provided during a practice session and posttest improvements in perceptual accuracy. Experiment 2 investigated the potential relationship between how often practice (PR) is provided during a practice session and posttest improvements in perceptual consistency. The results of both experiments are consistent with previous findings that perceptual accuracy improves only when practice includes KR and that perceptual consistency improves regardless of whether practice includes KR. In addition, the results showed that although there is a relationship between how often KR is provided during a practice session and posttest improvements in perceptual accuracy, there is no relationship between how often PR is provided during a practice session and posttest improvements in consistency.

Background: Virtual reality (VR) is an emerging technology that is proving to be effective in encouraging physical activity (PA) and improving health. Although regular PA has many advantages, physical inactivity continues to be a significant global health concern. Using an ActivPAL for PA assessment, this study examines the effects of an active video game (AVG) using VR on cognitive function among female university students.

Objectives: This study aimed to investigate the effects of external (EXT) versus internal (INT) focus of attention on acquiring and transferring simple and complex motor skills in novice female volleyball players.
Methods: Fifty-seven participants were assigned to one of the three groups: The external focus (EXT), the internal focus (INT), and the control group (CON). Over a 6-week intervention, participants practiced a simple skill (volleyball passing) and a complex skill (overhead tennis serve).

The prevalence of childhood obesity in South Africa necessitates the design and implementation of interventions to improve the levels of physical activity and nutrition among school-age children. This study aimed to evaluate the efficacy of a brief intervention to improve knowledge regarding exercise and nutrition among primary school learners in Tshwane, South Africa, using a quasi-experimental single-group, pre-post-test design. A total of 86 primary school learners from two primary schools participated in the intervention, which was guided by the Analysis Grid for Obesity-Linked Environments (ANGELO).

Objective: To verify the effects of two different detraining periods on the physical fitness of older adults with cardiometabolic risk factors.
Methods: This observational study encompassed older individuals with cardiometabolic risk factors, who were assessed after two different detraining periods: 1 month (1DT) and 3 months (3DT). Physical fitness was assessed using the 30-s sit to stand test (STS), 30-s arm curl, chair sit-and-reach, back scratch, timed up and go, and 6-min walk test (6MWT).
