Sports analytics has become very popular in recent years. Many researchers have been using the tools and technique to study tennis player performance in various aspects during matches. However, much of the studies were performed on male players while much less attention were made on female players. This study explores the female players’ characteristics and serve performance that leads to winning matches in women’s singles 2018 Grand Slam tennis tournaments. Using data provided by the official website of the Women Tennis Association (WTA), 1016 single matches in all four 2018 Grand Slam Tournaments were analysed to evaluate winning traits in tennis specifically looking at the two most important strokes in tennis which are the serve and return of serve. Additionally, other personal player characteristics that would influence the match outcomes were also evaluated. To achieve the objectives of the study, odds ratio and chi-square test were used to compare between the match winner and match loser. The study revealed that percentage of first serve return won (PFSRW) has the highest odds ratio value (OR=1.263) followed by the percentage of first serve won (PFSW) with odds ratio equal to 1.244. These showed that having a good first serve, plays an important factor in increasing the winning odds as compared to second serve either in serve or in return of serve. This study also reveals that a taller player had the advantage over a shorter player for faster serve speed (p-value<0.05).
SEES is an instrument used to examine the affective state of exercise associated with mood. This study was aimed to determine the psychometric properties of Malay version. The original scale underwent forward and backward translation, cognitive debriefing and field testing. The psychometric properties were evaluated based on reliability and construct validity among 152 smokers. The translated SEES had shown satisfied reliability with Cronbach alpha of 0.80, 0.73 and 0.73 and a significant positive correlation with Profile of Mood Scale (POMS). The current study provides psychometric evidence for an appropriate, reliable and valid tool for SEES Malay version.

This study examined a supervised moderate-intensity aerobic exercise programme’s effectiveness in regulating the Tobacco Withdrawal Symptoms (TWS) during temporary abstinence. This was a single group, pre and post-quasi intervention study. Thirty daily smokers participated in an 8-week supervised moderate-intensity aerobic exercise programme. We assessed the TWS, smoking urge, mood and stress-pleasure related hormonal variables after the aerobic exercise intervention. The measurements were conducted after overnight abstinence at baseline, post-intervention (at week-8) and post-detraining (at week-10). TWS components, smoking urge and mood were found to improve. For hormonal variables, cortisol and beta-endorphin except adrenaline showed insignificant changes at post-intervention and de-training. The findings suggest moderate-intensity exercise might help in reducing withdrawal symptoms and its adverse effects. Thus, exercise is an effective adjunct treatment in a smoking cessation programme.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
