The Effect of the Nature of Precued Parameters on Reaction Time of a Force Production Task
( Masoumeh Shojaei ),( S. M. VaezMousavi ) 한국스포츠정책과학원(구 한국스포츠개발원) 2007 International Journal of Applied Sports Sciences Vol.19 No.1
Results of previous studies on Parameter Precuing Technique suggested a relationship between reaction time (RT) and number and nature of precued parameters. Most of these studies only examined aiming movements as the experimental tasks. The present study was designed in order to test the effect of the nature of precued parameters on RT in a force production task. A mixed 3 factorial design was performed on non athlete right handed volunteer students (n=16; age=20 to 25). Having applied "Parameter Precuing Apparatus", subjects performed 2400 trials over 5 sessions on successive days (4 blocks of 120 trials per session) under different precued conditions of precuing. The task required production of defined isometric force (3 or 6 kg) toward inside or outside, with the right or left upper limb as quickly and accurately as possible after displaying the stimulus preceded by the precue. The subjects` RT in different levels of independent variable were analyzed by using 3 factor experiments (nature of precued parameter*gender*session) with repeated measures on two of the factors (type of precued parameter & session). It was found that the main effects of nature of precued parameter and session were significant (p<0.05); but the main effect of gender, interaction of nature of precued parameter and gender, and gender and session were not significant (p>0.05). The results are discussed in relation to their significance in the context of current theories and hypotheses on movement programming.

Background and Objective During the COVID-19 pandemic, there were increased reports of sleep problems. Individuals with poor sleep quality are at particular risk of reporting symptoms of anxiety, depression, and poor quality of life, along with substance abuse. The present study aimed to examine the effectiveness of combined physical activity and acceptance and commitment therapy (ACT) on anxiety and depressive symptoms and insomnia severity among individuals with poor sleep quality.Methods Participants were 60 males and females with mean age (standard deviation) of 39.29 (5.82) years. Participants were randomly divided into 4 groups of 1) physical activity, 2) ACT, 3) combination of physical activity and ACT, and 4) control. The study consisted of four stages: pre-test, interventions, post-test, and follow-up. Repeated measures analyses of variance were used to assess time by group interactions.Results The results showed that the symptoms of anxiety and depression and sleep problems were reduced for the physical activity, ACT, and combined groups, compared to the control group (p = 0.001). Superiority in all outcomes of the combined group was shown, compared to the other groups.Conclusions The present findings suggest that among individuals with poor sleep quality, combined physical activity and ACT intervention has the potential to reduce symptoms of anxiety and depression and insomnia severity. It further appears that health organizers should pay more attention to physical activity interventions in individuals with poor sleep quality.
