skateboard jumps.Frederick, Determan Whittlesey, and Hamill (2006) describe the ground reaction forces during the Ollie jump, Determan, Frederick, Cox, and Nevitt (2006) during the Kickflip jump.Although the study by Crockett and Jensen (2007) includes monitoring of muscle activity by electromyography (EMG), this study is primarily concerned with the ratio of the number of rebounds and speed of movement and comparison of muscle activity during various skateboard jump performances is missing.The aim of this study was to compare muscle activity in the basic skateboard jumps, the Ollie and switchstance Ollie. Methods SubjectsThe experiment involved 10 men without health problems aged 20.0 ± 4.6 years with height 1.79 ± 0.05 m

Background: The influence of parents on physical activity (PA) and body weight of their children is confirmed by scientific studies.However, it is not known whether only children or those with siblings have a higher level of PA and healthier body weight.Objective:The aims of this study are (i) to assess whether there are any differences in the achievement of the daily step count (SC) recommendation and in the prevalence of overweight/obesity between only children and children from families with multiple children, and (ii) to investigate whether the achievement of the SC recommendation by children/parents and parental overweight/obesity is associated with childhood obesity.Methods: The analysis included 566 families (10.6%/89.4% with single child/two or more children) with complete data on weight status and PA monitored with a Yamax pedometer during regular school/work between 2013-2019.The daily SC recommendation amounted to ≥ 13,000/11,000 SC for 5-12-year-old sons/daughters and ≥ 10,000 SC for 12-16-yearold adolescents and adults.The chi-square test was used to compare the achievement of the daily SC recommendation and the prevalence of overweight/obesity.Binary logistic regression analyses were used to investigate whether the achievement of the daily SC recommendation by children/parents and parental overweight/obesity were associated with obesity in their offspring.Results: A significantly higher proportion of children with siblings achieved the recommended daily SC (51.8% vs. 31.7%,p = .003)and showed a lower prevalence of overweight (16.2% vs. 20.0%,p = .041)and obesity (7.1% vs. 20.0%,p < .001)compared with only children.The achievement of the daily SC recommendation in children significantly (p < .05)decreased the odds ratio of obesity (odds ratios 0.22-0.34,95% confidence intervals 0.07-0.85).Conclusions: Children from families with siblings had higher physical activity and healthier body weight than those from single-child families.However, reaching the recommended daily SC reduces the likelihood of childhood obesity, regardless of the presence of a sibling in the family.

Background: Several studies have compared the physical, physiological and anthropometric characteristics according to age and playing position in soccer.However, no studies have researched the comparison of emotional intelligence (EI) levels of soccer players.Objective: The purpose of this study was to compare the EI levels of soccer players in their age and playing position.Methods: A total of 550 male soccer players were divided into four groups according to their age: under-17 (n = 135), under-19 (n = 131), under-21 (n = 144) and 22+ (n = 140) and playing position: goalkeeper (n = 101), defender (n = 159), midfielder (n = 148) and forward (n = 142).EI levels of soccer were evaluated through the Emotional Intelligence Inventory in Sport.Results: Players in the lowest age category showed significantly (p < .001)higher EI level.Moreover, midfielders have also significantly (p = .039)higher EI level than other players.Conclusions: The results of this study indicated that the level of EI varies according to players' age and playing position.These findings might be used for the evaluation of psychological and physiological responses required for soccerspecific performance.

1 back pain is a common complaint among them (Pimentel et al., 2020).The prevalence of neck and low back pain is higher in SBP than in other postural abnormalities (Lewis & Sahrmann, 2015).The low back pain in this group of athletes may result from the spinal muscle variations that have occurred due to the SBP.Literature has indicated people with SBP experience forward displacement of the pelvis and backward displacement of the thoracic region (Dolphens, Cagnie, Coorevits, et al.,

feedback of relevant metrics, thus greatly aiding coaching staff to modify different variables in training programs related to the physical and physiological demands of the players (Casamichana, Román-Quintana, Castellano, & Calleja-González, 2015).Likewise, it is useful to provide a detailed summary of the training load (volume, intensity and frequency;Foster et al., 2001;Scott et al., 2013).In that sense, analysing cumulative load with and without match data can provide different interpretations and it is expected that starters and/or players with higher match participation will have higher cumulative load values (Oliveira et al., 2021).Therefore, to be effective, training programs in soccer keep a relation to the loads imposed during matches (i.e., relative training load; Modric et al., 2021).Coaches require an adequate distribution of training load between the previous and the following match, to achieve a desired adaptive response and thus avoid the fatigue that may affect players' performance in competition

Background: Many young people spend a significant amount of time playing esports and video games during the day and meet their social and psychological needs on these platforms.This situation can lead to people developing an addiction to esports games over time.This situation brings about many problems, notably the gradual isolation of individuals from social life over time.Especially during university years, many individuals turn to esports games as a way to escape from various issues.There could be numerous reasons for this inclination.Objective: This study aimed to uncover the factors contributing to university students' addiction to esports games.Methods: The study utilized the Q Method, incorporating qualitative and quantitative research features.Twenty-six university students who play games for at least 21-24 hours a week were included in the study group.The study group was determined using the snowball sampling method.The principal component analysis method was used to analyze the data.Results: The factors that contribute towards university students' addiction to esports games are wanting to socialize and make new friends, wanting to be a professional-level esports player and earning money by sharing game videos on social media.Conclusions: The study's findings suggest that various factors, including psychological, economic, social, and professional aspirations, contribute to esports addiction.It was also shown that there are individual benefits that contribute to the formation of addiction to these games, as well as the potential harm that esports games can cause to individuals.
