Weight (resistance) training can increase strength and muscle mass. A personalized training protocol (i.e., with optimum frequency and number of sets) was followed for 4 months by a 40-year old male with 20 years of weight training experience. The body was split in three parts and was trained every 5-6 days. The strength increase was between 7% (back) and 17% (legs), while the free-fat mass increase was 0.4 kg (0.5%), which was lost after the 4-month period. It was shown that reduced sleep duration for one night did not affect the strength performance. However, with 2 days of reduced sleep, there were indications of worse performance. The results confirm the importance of personalized weight training programs and good sleep habits for strength improvements.
This study documents that a personalized weight (resistance) training programs can result in strength increases even for advanced trainees. This study contributes in the existing literature showing that one-night sleep restriction only slightly affects strength performance, but two nights of reduced sleep duration have a negative effect.

The problem of physiological study of non-traditional means of coaching attracts a lot of scientists’ attention in recent years. This is due to the need to provide a maximum development of certain muscle groups and direction of the coaching process. Proper use of simulators weight machines bring positive results (Valeria et al., 2018). Obviously, an important step in the use of technology is the right choice for team sports coaches and personal trainers for the effectiveness of the coaching process. One effective component of this process is the inclusion to a coaching program with the help of physical exercises would be TRX® function loops. Among specialists of functional and physical coaching innovation as TRX® – coaching is one of the best equipment for complex solution of the tasks. This exercise is an exercise using body weight. It was designed to develop strength, power, core stability, flexibility and balance. TRX® is the valuable creation for the sports industry of any levels. TRX® Coaching –Suspension Coaching became commonly usable for Fitness Health Clubs, Professional Sports and Elite Strength Conditioning Workout for Sports Teams (Dao and Le, 2018). Therefore, it was suggested the use of TRX® exercises in preparation of basketball players. The results of the study clearly show that the inclusion in the 18-25 years old basketball player coaching program with the TRX® functional loop contributes to a significant increase in overall fitness levels and ability to foster gas of life. Using TRX® during coaching can be considered to be an important factor in increasing the effectiveness of basketball preparation

Dimakopoulou E. , Sakka P. , Karydaki M. , Margioti E. , Theodorelou M. (2018). Association between Physical Activity, General Health and Burden of Dementia Caregivers. Journal of Sports Research, 5(1): 24-32. DOI: 10.18488/journal.90.2018.51.24.32
Most caregivers do not engage in physical activity programs despite evidence that physical exercise improves general health and relieves symptoms of depression, anxiety and stress. The aim of the study is a) to investigate the amount of physical activity of caregivers in everyday life, b) to examine the reasons of limited participation in physical activities and c) to find out if limited participation in physical activity affects their general health. Fifty three (n=53) caregivers (59.04±12.76 yrs) were recruited by a Dementia Day Care Center. A caregiver questionnaire was designed to obtain information on basic demographics, living habits and current care details (hours of care, etc). The Greek version of PASE questionnaire was used to measure the amount of physical activity undertaken by caregivers. Caregiver burden was assessed via the Greek version of the validated Zarit burden interview and general health was investigated via the Greek version of General Health Questionnaire (GHQ-28). All data were analyzed by using SPSS, version 22. The majority of caregivers are daughters or wives. The current sample had a PASE mean score of 168.0±87.46. Differences in PASE score were found between occupational status (F=6.210, p=0.001) and living arrangements (F=3.882, p=0.05). No differences were found in PASE score between different levels of burden (F=1.058, p=0.376). PASE score was not related to GHQ28 scores. High correlations were found between ZBI and GHQ28 total (r=0.71, p=0.001) and ZBI and GHQ28 four subscales (somatic: r=0.62, p=0.001, anxiety-insomnia: r=0.66, p=0.001, social dysfunction: r=0.54, p=0.002, severe depression: r=0.44, p=0.003). ZBI was also correlated with years of care (r=0.38, p=0.004) and hours of care/day (r=0.40, p=0.003). The most frequent barriers to physical activity cited by caregivers were their living arrangements and their occupational status. In addition, burden was not cited as a significant barrier.
This study is one of very few studies which have investigated the amount of physical exercise of dementia caregivers and connects it with other important aspects of caregiving, as general health and their burden. Additionally, this paper explores the possible reasons that caregivers do not engage in physical exercise.
Comparison of Recover Heart Rate Status among 4th Year Male Sport Science Summer Program Students, Wollega University, Ethiopia
Edosa Jabesa (2018). Comparison of Recover Heart Rate Status among 4th Year Male Sport Science Summer Program Students, Wollega University, Ethiopia. Journal of Sports Research, 5(1): 18-23. DOI: 10.18488/journal.90.2018.51.18.23
This study aimed to experiment, measure and evaluate the level of recovery heart rate among male sport science students of the summer program and to compare their mean with the standard status of the recover heart rate rating scale. From a total population of 80, the sample consisted of 40 male sports science students. The samples were selected by using a random sampling technique. The subjects were divided into two equal sections on a random basis (section A, and section B) consisting of 20 subjects in each group. Harvard step test was used to measure the recovery heart rate of the students' wich is an index of cardiovascular fitness. To compare the mean differences among the students independent t test was applied with the help of SPSS (version, 20) Software. The level of significance was set at 0.05. The findings of the current study show that the mean value of recovery heart rate for section A was calculated 104.2 with S.D. 3.4 and section B was recorded 106.8 with S.D. 2.24 respectively. The t-value on recovery heart rate is 2.924 which are greater than the required table value (2.021) with 38 df. So there is a statically significant difference in the recovery heart rate variable between section A and section B sport science students. There were statistically significant mean differences in recovery heart rate among the section A and section B male students, also the recovery heart rate level of the subjects was below the standard level of recovery heart rate rating scale.
This study contributes in the existing literature as the first investigation to comparatively examine the level of recovery heart rate among the students and to compare their mean with standard status of recover heart rate rating scale set by YMCA. The paper´s contribution is increasing the participation of subjects in regular physical exercise which is important for preventing themselves from different chronic disease.

Mykal Manswell , Scott P. Barnicle (2018). Athletic Identity and the Transition Out of Sport among Division I Football Players. Journal of Sports Research, 5(1): 12-17. DOI: 10.18488/journal.90.2018.51.12.17
Athletic identity is a key factor in multiple areas in a student-athlete’s career however, athletic identity is both fragile and critical simultaneously, effecting things such as self-confidence, self-identity, and reputation around campus. Through interviews with 10 football players at a Mid-Atlantic American Division 1 University, qualitative data was gathered examining interests outside of the sport, their process of becoming a Division 1 athlete, and preparation for life after football. Primary findings explored common trends among the participants such as shared long-term goals, sport attached identity, and the absences of post athletic-career skills, or even exposure to such skill training at their university. Additional results suggested participant student-athletes have a solid sense of who they are but do not have a stable outlet for who they want to become outside of sport. This study can inform universities that student athletes not only desire innovative methods for career development, but also possess diverse ideas for their future beyond the student-athlete experience.
This study is one of the very few studies which examine the current state of post-athletic career resources available to American Division 1 collegiate athletes. From an athlete-identity framework, this quasi-experiemental study sheds light on the current state of elite Division1 football through the lense of a student-athlete.

Dao Chanh Thuc (2018). The Effect of Physical Activities on Biological Age Parameters of Females from 17 to 18 Years Old. Journal of Sports Research, 5(1): 7-11. DOI: 10.18488/journal.90.2018.51.7.11
The effect of weekly physical activity on biological age (BA) parameters, we have conducted a study 215 females from 17 to 18 years old who were divided into the experimental (EG, n=105) and control (CG, n=110) groups. It was established that if at the end of the experiment the BA parameters of the females CG weren’t a significantly different from the average data (p>0.05), then there was a statistically significant decrease in the BA parameters of the females EG. This was confirmed by statistical probability (p<0.01), which suggests the dependence of biological age parameters on the extent of weekly physical activity.

The purpose of the study was to improve the medical and pedagogical support of the training process of athletes with signs of connective tissue dysplasia by substantiating the early criteria of acute physical overstrain of the cardiovascular system. 132 athletes were examined, 31 of them with signs of systemic involvement of connective tissue in the dysplastic process. Early signs of overstrain of cardiac function during exercise of athletes with signs of connective tissue dysplasia were symptoms of disturbance of myocardial relaxation by the indicators of diastolic function of the heart, therewith the ejection fraction at rest can be maintained at normal levels. The presence of signs of connective tissue dysplasia in athletes with different predicted states requires sports doctors and trainers to conduct in-depth analysis and differential diagnostics of clinical forms in order to prevent complications during training competitive loads.
