    Abstract Background and Study Aim. There is no doubt that the Coronavirus disease (COVID-19) pandemic, and its related containment measures such as lockdown and social distancing, is affecting physical activity and sleep quality  of the general population worldwide. Algeria, one of the most affected countries in Africa, entered the lockdown on March 9, 2020. Numerous studies have explored the interaction between physical activity and sleep quality showing the effect of physical activity levels on sleep, yet previous researches have not investigated the relationship between physical activity and sleep quality during lockdown. The main purpose of the present study was to investigate the association between physical activity and sleep quality in quarantined individuals.
    Material and Methods.  A national Google online survey was conducted between 16th April and 25th May 2020. 1002 Participants responded to the Pittsburgh Sleep Quality Index (PSQI) questionnaire and the short form of the International Physical Activity Questionnaire (IPAQ). Of the 1002 participants who completed the survey, 358 were students. The final data were collected from the respondents.
    Results. The COVID-19 home confinement led to a decrease in physical activity levels. However, the majority of the study population had good sleep quality (61.9%), while only (38.1%) had poor sleep quality. In addition, women are less physically active than men (p < 0.01). Moreover, there was a significant difference in sleep quality between sufficient and insufficient physical activity groups (p < 0.05).
    Conclusions. Our results show that Algerian adults have low levels of physical activity, good sleep quality, and poor sleep quality is associated with insufficient physical activity in adults during lockdown.

    Abstract Background and Study Aim. One of the fastest racquet sports in the world, badminton is defined as a versatile, explosive sprint sport that requires players to perform intense rhythmic movements with its highly competitive and dynamic feature. The aim of this study is to investigate the effectiveness of 4-week badminton training on some selected biomotoric features in young individuals engaged in recreational sports.
    Material and Methods. Twenty seven students of sports sciences voluntarily participated in the study (age = 18,85 ± 0,98 years). A total of 4 weeks of training was given for 2 hours a day specific to badminton sport. We examined the effects of pre-post training development of biomotoric properties, flexibility, reaction, vertical jump, balance and agility parameters on performance. Statistical analyzes of the data obtained as a result of the research were obtained using the IBM SPSS 23.0 package program.
    Results. The differences before and after badminton training, a statistically significant difference was found between pretest and posttest measurements of flexibility (5.53%), reaction (24.66%), vertical jump (8.93%), and agility (2.54%) tests (p<0.05). In the balance test, although there was a mathematical difference of 17.84%, this difference was not statistically significant (p>0.05). Finally, 4-week training improves flexibility, reaction, vertical jump and agility performances in a positive and meaningful way (p<0.05).
    Conclusions. The findings showed that the training method specific to badminton sport improved the flexibility, reaction, vertical jump and agility performances of individuals compared to pre-training. Specifically, these results revealed that the training-performance relationship clearly affects each other positively. In future studies, it can be predicted that more multidisciplinary training methods will be directed to research by making macro plans.
