Keywords: Out-of-school physical activity,  activity trackers,  self-regulation
Background: Children’s physical activity levels continue to decline with age. Wrist worn accelerometers are accessible and worn by
many children; however, research examining the effects of wrist worn accelerometers on children’s physical activity levels has not
been conclusive. Methods: 25 children were given a wrist worn accelerometer for 4 weeks (1 week sealed; 3 weeks unsealed) and
information about physical activity and fi tness to increase their in- and out-of school physical activity. Results: Multivariate analysis
revealed a signifi cant difference for in-school (p=.021) and out-of-school (p=.012) activity between weeks 2 and 3, suggesting reactivity
to the wrist worn accelerometer. Males were signifi cantly more active out of school (p=.017). Additionally, our results indicated
that Asian students [M=7879.6(±481.1)] were getting signifi cantly fewer moves than African American students [M=9439(±367.5)].
Conclusions: This study demonstrated that the use of activity trackers and information alone could not be suffi cient in improving
physical activity levels among 5th graders.

Keywords: Six-intensity zones,  Aerobic,  anaerobic,  physical,  motor capabilities,  athletes
The training according to the six intensity zones the modern training and sports which exceeds the variables and conditions that occur in
in contests, sports competitions as well as its importance in preparing sports, Training intensity zones include (Lactic acid, The maximum
oxygen consumption, Anaerobic threshold, Phosphagen system, Oxygenic threshold, Oxygen compensatio). The research aims to build
a training curriculum for the six intensity zones that suits the capacities the research sample and identify the rates of evolution and the
impact of the training curriculum in physical and motor capacities of the the research sample. The researcher used the experimental
method designed control and experimental groups, so as to suitability and the nature of the research problem. The research sample
selected by the way to improbability manner of the Accidental Sampling and sometimes called (CONVENINCE SAMPLING), For ages
(16-18) years representing sports games (Taekwondo, Weight lifting, Futsal, Swimming, Handball). The duration from (21/2/2016) to
(18/4/2016), It has been identifi ed physical capacities tests which included vertical jump from steadiness to measure the explosive power
of legs, and test of knees bent in a (20) seconds to measure the characteristic speed and strength, and run switchback (25 m × 8) test to
measure the assume (tolerance) speed, and determine the tests of motor capacities w hich included the the core fl exion from standing
for measuring the core fl exibility and barrow test to measure fi tness. The training curriculum was applied for (8) weeks of (5) training
units per week, The researcher concluded outweigh the experimental group that worked on according to the intensity zones in most of
the physical and motor capacities tests, but the fl exibility Capability did not appear any signifi cant difference between the experimental
and control groups, and there was also a clear outweigh in the experimental group in the rates of development for physical and motor
capacities except fl exibility, it was almost equal proportions in which evolution, The effect was tilted in favor of the collective Games, At
the expense of individual Games. The researcher recommended the adoption of the training according to the intensity zones rather than
relying on training in according to aerobic and anaerobic energy systems, Without ignoring the nature of the prevailing energy system
at sports activities, and avoid the training according to six intensity zones for ages under 16 years.

Keywords: Physical measurements,  force distinctive,  speed,  jumpers
The scientific progression in the field of sports has seen a remarkable development in various levels and for most sports, achieving a
quantum leap in establishing great achievements in some sport games. Today we are in dire need for more effort to achieve a bright
future that ensures the sports movement scientific advancement and progression at various levels. Through the revision done by the
researcher of a number of studies and researches which included physical measurements, he noted that each physical activity owned
specific physical measurements qualifying to reach high levels of competition for this activity. The researcher intended to identify the
relationship between the height and the force distinctive with speed among the athletic students, in the fourth grade in the faculty of
physical education and Sport Sciences/University of Baghdad. The study included a sample of the fourth grade students. They were
26 students. The sample was divided into two groups, the first group included students whose heights exceeded (177 cm). The second
group included students whose heights were below (165 cm). For the period from 01/01/2016 to 05/01/2016. The force distinctive
with speed was measured for both legs in the two groups. The results showed no significant correlation (P≥ 0.05) between age and
choosing the vertical jump of fortitude, and between age and choosing medical ball pushing. Results also recorded the existence
of a significant correlation (P≤ 0.05) between the (weight - thigh circumference) and choosing the medical ball pushing. As well as
a significant correlation (P≤ 0.05) between the length of the hummers and choosing broad jump of stability, vertical jump of stability
and pushing the medical ball. The results also recorded the existence of a significant correlation (P≥ 0.05) between the length of the
forearm and the broad jump of stability test and pushing the medical ball. The most important conclusions that have been reached that
there was a significant correlation between height and force distinctive with speed among the jumpers of the broad jump of stability.

The Relation between Achievement Motivation andPerformance of Forehand and Backhand Shooting Skills in Badminton for First Stage Female Students
Saif Abdul-Zahra Hamza
Keywords: Achievement motivation,  performance,  shooting,  skills,  badminton
The game of badminton is one of the individual games that got quick leaps in skill, physical and tactical development, so it became
constantly evolving in line with the progress that has occurred in all various sports. However, the game faced obstacles in preparation
and conditioning of players to get to a higher level and to achieve the desired goals of sports in each game. There is no doubt that
the psychological factor is one of the many and important developmental requirements as this factor has a profound impact on sport
achievements like other (physical, skill and tactical) factors. Sports psychology is one of the important rules in the training process
without which it is difficult to reach the level of integrated achievement because this factor is the content of training and effective on what
is owned by athletes in terms of high capabilities and potential. In addition, achievement motivation is one of the drivers of conduct,
performance, and even a key for sports practice. When it reaches a certain level, it leads to satisfactory results as it works to reduce
space and bring distances to upgrade the performance of students and their better advancement. Thus achievement motivation is
one of the early works that teachers should develop. The research problem is to know achievement motivation and its relationship to
accurate performance of forehand and backhand skills in badminton. The present study aims to identify the achievement motivation for
female students of the first stage in Faculty of Physical Education and Sport Sciences/Baghdad University as well as identification of
measuring performance accuracy of backhand and forehand shooting skills by female students of the first stage in Faculty of Physical
Education and Sport Sciences/Baghdad University. The study sample has been selected of students in the first stage at Faculty of
Physical Education and Sports Science and the number of respondents was (23 female students) for the academic year 2015-2016
and for the period from 06/12/2015 until 28/04/2016. The study used the descriptive method and statistical method including the
arithmetic mean, standard deviation and Pearson correlation coefficient to analyze the results. The results showed that there was
no significant correlation between achievement motivation and measurement of performance accuracy of forehand and backhand
shooting skills in badminton for students of the first stage in Faculty of Physical Education and Sport Sciences/Baghdad University.
Findings of the study conclude that female students do not have the motivation of achievement in forehand shot of badminton while
they have the motivation to achieve the backhand shot in badminton. Hence, the importance of the psychological aspect must be
stressed through psychological and mental tests to see the performance of student through encouragement, rewards and foreign
motivations and develop their motor performance in the field of badminton as well as emphasis on the development of footwork and
physical capabilities in the performance of skill tests for female students and conduct studies of the relationship between achievement
motivation and various other sports.

Zeghdar Moufida • Chiha Fouad • Hamiouda Halima • Benfetima khadija • Rouabah Leila
Keywords: Menstrual cycle disorders,  footballers,  energy deficit,  oestradiol,  injuries
Introduction: Le niveau des compétitions sportives féminines a connu une croissance tellement marquée que la pression est devenue
plus palpable poussant certaines athlètes à se lancer dans des régimes alimentaires déséquilibrés pouvant perturber leurs cycles
menstruels. L’association entre troubles de l’alimentation et cycles menstruels irréguliers finirait par engendrer “ la triade de l’athlète
féminine’’. Objectif: l’objectif est d’évaluer la fréquence des troubles du cycle menstruel et de mettre en évidence ses causes chez
la footballeuse algérienne. Methodologie: 44 footballeuses ont renseigné le questionnaire sur leur cycle ovarien pour l’analyse de la
fréquence des troubles du cycle menstruel. Les sujets ont aussi réalisé des mesures anthropométriques et une enquête alimentaire.
Les blessures subies par les footballeuses ont été recensées. Resultats:12 footballeuses (27,27%) ont présenté des troubles du cycle
dont 5 avec des antécédent d’aménorrhée, 5 avec des cycles irréguliers longs (≥ 35jours) ou courts (≤ 24 jours) et 2 présentant à la
fois des antécédents d’aménorrhée et des cycles irréguliers. Nos résultats ont apporté des valeurs du poids et de taille compatibles
aux normes du football féminin. En comparaison avec les footballeuses normalement réglé (NR), les footballeuses présentant des
troubles de cycles menstruels (TC) présentent un déficit énergétique associé à un IMC plus bas et un taux d’oestradiol réduit. Les
athlètes (TC) présentent une fréquence de blessures plus élevé comparées aux athlètes (NR). Conclusion: La pratique du football a
tendance à perturber le cycle menstruel des footballeuses (27,27%) pouvant suspecter le syndrome de la triade de l’athlète causée
essentiellement par la baisse des apports énergétiques journaliers et confirmée par le pourcentage élevé des blessures subies.
