If the average personal trainer had a dollar for every time a new client identified a history of knee pain during their pre-exercise screening, they’d have a solidly reliable passive income stream.
This hip mobility assessment from Justin Price, creator of The Biomechanics Method®, is a simple activity that can help identify risk of knee pain in new and existing clients. Understanding how the relationship between mobility and strength can cause dysfunction is a key factor for keeping your clients injury-free and primed for optimum performance. Introduction Soccer, one of the most popular team sports worldwide, has an irregular and intermittent activity profile [2, 20].
Publication of this journal is financially supported by the Ministry of Science, Technology and Development Republic of Serbia. As many of the largest, most powerful muscles of the body cross the hip and attach to the leg, any restrictions in these muscles can affect the correct functioning of the hips.

In specific situations, such as the penalty kick, a faster ball could be kicked in such a way that no professional goalkeeper could reach it in time, no matter how skilled and well trained. Focusing on the penalty kick is not only important during the game, but also in player selection and training. Since the introduction of the dramatic penalty shoot-out, penalty kicks have played a decisive role in important championships, determining the winner of the 1994 and 2006 World Cups. Several factors have been considered as key in the penalty shoot-out, such as stress, fatigue, and both the kicker's and the goalkeeper's techniques [1, 13, 17]. Deciding the winner after 90 or 120 min of play can be a very stressful situation, which, added to the high level of fatigue that most player experience towards the end of the match [20, 24], might result in significant impairment of the kicker's performance [13]. Physical fatigue or muscle weakness (or "lack of strength") is a direct term for the inability to exert force with one's muscles to the degree that would be expected given the athletes' general physical fitness.
Fatigue involves the development of less than the expected amount of force as a consequence of muscle activation that is associated with sustained exercise and is reflected in a decline in performance [24]. Besides, fatigue causes biomechanical changes such as the decline in leg power, maximum isometric force alterations and activity of the quadriceps [21], the decline in the vertical jumping ability [26], changes in ground reaction forces and joint kinematics of running [19, 28] and increased lactate production [4]. Developing methods comprehensive enough to investigate all the variables involved is a complex challenge that is receiving growing attention in scientific literature. However, the effect of muscle fatigue on kicking kinetics and kinematics has never been systematically examined. All the trials were subjected to a 3-D mechanical analysis using Simi Motion Program. Figure 1. The penalty kicks testing procedure Fatigue Exercise Protocol The subjects performed a 45 min intermittent exercise protocol, divided into three 15 min intervals, with performance times and heart rate (HR) values monitored throughout. All the four cameras were synchronized while photographs were taken, and a 100c A— 100c calibration box was placed before the cameras (Figure 2). Figure 2.
Commercial SPSS (Statistical Package for the Social Sciences) version 11.0 for Windows was used for the statistical analysis.
Statistical evaluation was performed by One-way analysis of variance (ANOVA), Least Significant Difference (LSD) and Pearson's correlation coefficient. Results The differences between the biomechanical variables for 3 stages of fatigue protocol intensities (75%- 85% - 95%) are shown in Table 1 (a & b).


No difference was observed in all biomechanical variables (F = 3.06) except for Knee Right on X-axis, Toe Right on Z-axis, Heel Right on Z-axis and Kick Accuracy.
We can observe significant differences between the First stage measurements (75% intensity) and the Second stage measurements (85% intensity) in Knee Right on X-axis, Toe Right on Z-axis, and Heel Right on Z-axis for the Second stage measurements (85% intensity), adding significant difference between the First stage measurements (75% intensity) and the Third stage measurements (95% intensity) in Knee Right on X-axis, Toe Right on Z-axis, Heel Right on Z-axis and Kick Accuracy for the Third stage measurements (95% intensity), and significant difference between the Second stage measurements (85% intensity) and the Third stage measurements (95% intensity) in Knee Right on X-axis, Toe Right on Z-axis, and Heel Right on Z-axis for the Third stage measurements (95% intensity). Analysis of variance between measurements of the mechanicals of the three anatomical points, the moment of impact with the ball and the accuracy and strength of correction penalties in the sample Table 1 a & b, which is related to analyzing the difference among biomechanical changes to discover the effect of physical fatigue on the accuracy and strength of shooting penalty kicks, shows that there were no statistical differences among the three measurements for the specific anatomical points, and accuracy and strength of shooting, except for the horizontal displacement move of the point on the right knee on X-axis, and the vertical displacement move of the right toe on Z-axis (foot) and ankle on Z-axis. It also shows that there was a statistical link between accuracy level measurements and so the researcher will specify the differences between the average least significant differences to ensure the reality of results.
Analysis of variance between measurements of the mechanicals of the three anatomical points, the moment of impact with the ball and the accuracy and strength of correction penalties in the sample Table 2 shows that there were statistical differences among the three research measurements of average penalty kicks, after exercising for the first, second, and third interval of 15 minutes. The result of the second measurement was higher than the first one, and that of the third was higher than the second in all variables except the accuracy means. Therefore, the results show that there were statistical differences between the first and the third measurements while there were no statistical differences between the first and the second measurements or between the second and the third measurements.
The differences among the three measurements of the mechanism of the joints at the moment of kicking the ball and the accuracy of the penalty kicks for the sample under investigation Table 3. The correlation between the three measurements for the mechanism of the joints under investigation at the moment of kicking the ball and shooting strongly Table 3 shows the link between the mechanical variables under investigation and the strength of penalty kick shooting, which comprised 48 trails for each of the three measurements in the research used to measure the horizontal and vertical displacement at the moment when the kicking foot hits the ball. The results shown in the table indicate that there are statistical correlation links among the chosen mechanical variables on the one hand, and the strength of shooting on the other hand in the three research measurements, some of which are functional while others are not. Table 4 shows the relationship between the biomechanical variables and the accuracy of the penalty kick. The correlation between the three measurements for the mechanism of the joints under investigation at the moment of kicking the ball and accuracy shooting Figure 3 a, b, c, d.
Average values of biomechanical variables during the protocol Discussion The aim of this study was to investigate the effectiveness of intermittent exercise fatigue on certain biomechanical indicators for accuracy and strength of penalty kicks among soccer players.
We used a protocol that considers the mechanical demands of the intermittent running characteristic of soccer, replicating the short duration of exercise bouts, and subsequently providing a valid frequency of speed change in light of the different intensities. The research attributes this difference to fatigue caused by the nature of shooting in soccer, where the player has to pivot on one foot (the pivot foot) and sway the other foot (the kicking foot). If we consider the basic controls of the links movement, we will find that the displacement moves from the fixed to the flexible joints, and this is a group in a series connected with each other by open joints that do not close. The angular velocity of the thigh continues to increase and reaches its peak value (~516-573 dega€?s-1) just before the knee starts to extend. At this point, the thigh angular velocity equals the shank angular velocity and, thus, the knee joint velocity is zero.
It declines and the shank velocity increases linearly until the ball impact reaches values of 1891 dega€?s-1 [6]. At ball impact, the thigh angular velocity is almost zero while the shank and the foot reach peak angular velocity and zero acceleration.


Hip flexion moments reach maximal value at the end of the backswing whereas maximal knee extension values are observed immediately afterwards, approximately at the end of the leg-cocking phase [22]. In this series, the parts should be mutually pushed until a certain move occurs, and each part of the series is provided with a pushing muscle force that can isolate or fix any joint. The movement of the fixed part is also followed by a movement of the successive parts, and so the last part has the greatest magnitude of movement which resembles a whip movement. The researcher attributes this to physical fatigue related to the differences between the horizontal displacements of the right point on the X corridor between the three measurements. The knee made a complete stretch in non-fatigue conditions, while it made a partial shrink in fatigue, thus causing mistiming. Kicking the ball is affected by several factors, the most important being various elements of technique (kinematical changes) [17].
Besides, during the course of a soccer match, especially towards its end, players suffer from muscle fatigue due to the repeated bursts of intensive game activities.
Even in elite soccer players, the effect of fatigue is noticeable and is reflected in a decline in performance, which demonstrates that leg muscle fatigue increases and strength declines towards the end of a 90-minute soccer-specific intermittent exercise bout. Typically, players find it difficult to retain leg muscle strength during the game due to muscle fatigue. It can be assumed that an induced leg muscle fatigue somehow disturbs maximal kicking performance and also leads to a less coordinated kicking motion [20, 24, 25, 27]. We observed that significant differences between the 3 fatigue protocol intensities affected the accuracy and strength of penalty kicks among soccer players.
In Table 4 there are links between the mechanical variables and shooting strength for 3 stages of fatigue intensities. When the player hits the ball, the resulting force from the foot move represents the outer force for the ball, so the displacement of the back swings in the beginning of the preparatory stage and the returned swing stage to the moment of the kicking foot hitting the ball affects the kicking strength directly. This result is supported by Dorge et al [5] and Nunome et al [23].
As for lower leg angular velocity, lower leg motion during kicking is known to be executed by the controlled application of the resultant joint moment and the moment due to segmental interactions. This contributed to fatigue and physical effort on the muscles as a result of the exercises which players had done before penalty kicks for 45 minuets divided into three 15 - minute intervals. There were no significant correlations between accuracy and physical fatigue for some biomechanical indicators in the first fifteen minutes of the protocol and apparent differences exist between accuracy and biomechanical variables after 30 and 45 minutes of the protocol followed.
