Opis:
Platelet-rich plasma (PRP) is being increasingly used in the modern medicine as a material stimulating, regenerating and accelerating tissue healing, including muscle injuries in sports. The aim of the present study was to determine the effect of PRP on strength recovery in exercise induced muscle damage (EIMD). A baseline value was established in six healthy male volunteers during maximal voluntary strength isometric contractions (MVC) of the elbow flexors in both arms. This was followed by MVC performance (80% IRM) concentric-eccentric exercise of both elbow flexors until point of exhaustion, and 24 h later the subjects were injected with PRP in the non-dominant arm (PRP-arm). Maximal isometric strength and muscle soreness was compared before and at 24, 48, 72 and 96 h after delayed onset muscle soreness (DOMS) between the arms. The results indicate that the muscle soreness was significantly decreased in PRP administered arm when compared to control-arm, however, the levels for isometric flexors peak torque (PT) and average strength (AS) significantly declined in the bout arm post exercise induced muscle damage. Administration of PRP had no effect on the muscle strength parameters, however, flexor PT values were higher in PRP administered arm compared to the control arm, but this was only achieved on the second day of post-exercise induced muscle damage.

Opis:
The study assesses the effects of a six-week plyometric training program (PT) on muscle stiffness in the dominant and non-dominant leg in male collegiate volleyball players. The study group comprised 16 volleyball players who had played collegiate volleyball for at least four years. For six consecutive weeks, twice a week, the players undertook a plyometric program of 60-min training sessions, each preceded with a specialist warm-up. The analysis of the anterior muscles of the right and the left lower leg revealed a significant increase in stiffness in the muscles of the right leg and the left leg. No significant differences were found between the anterior muscles of the left lower leg and the right lower leg in particular weeks of the training program. The analysis of the posterior lower leg muscles revealed no significant differences, either in the consecutive weekly training microcycles or between the left leg and the right leg. The measurement of muscle tone and biomechanical properties of muscles can be used as a fast and direct assessment of plyometric training-related muscle fatigue. A similar level of muscle stiffness in both lower legs (symmetry) is a reflection of the appropriate selection of plyometric training loads.

The aim of our 10-week-long experiment was to investigate the impact of training with additional dead space (DS) on spirometry and exercise respiration. Respiratory muscle training is applied to the development exercise capacity. Twenty cyclists were assigned to two groups: the experimental (E) and the control (C). All of them carried on with their initial training programme. During endurance trainings (twice per week) group E used additional DS (1000 cm3). Immediatelly before and after the experiment each participant was submitted to a spirometry and a continuous test. The spirometry test measured peak inspiratory (PIF) and expiratory (PEF) flows, forced expiratory volume in one second (FEV1) and forced vital capacity (FVC). The continuous test measured tidal volume (TV), respiratory frequency (RF), along with inspiration and expiration times. Our experiment demonstrated TV increase and RF decrease in both groups. In addition, the TV value was significantly higher in group E than in C. The PIF value also increased significantly, PEF and FEV1 upward trend was observed in group E only. We concluded the additional respiratory DS used in the experimental group provoked an increase of airflow observed in the spirometry tests at rest and during intensive aerobic exercise.

Opis:
Quantification of eccentric hamstring strength within elite youth sporting populations is a contemporary issue within practice. The aim of the study was to identify the reliability of eccentric strength metrics obtained via isokinetic dynamometry (IKD) and the NordBord in an elite youth football population. Furthermore, relationships between the strength metrics exhibited by the two devices were observed, to ascertain whether level of performance on one device can indicate how athletes will perform on the other. Twenty-one elite academy footballers completed two measures of eccentric hamstring strength on each device (60°·s-1 and 180°·s-1). Test-retest reliability was determined through Pearson correlation analysis. Relationships between strength metrics (IKD: PT, AvT and oPT at 60°·s-1 and 180°·s-1; NordBord: PF, AvF, PT, AvT, Ɵ) obtained on both devices were identified for analysis. Test-retest of both devices identified significant correlations for all eccentric strength metrics (P=≤0.05). Significant unilateral (L) relationships between PT, AvT (IKD 60°·s-1; 180°·s-1), break angle (Ɵ) (NordBord) angle peak torque (oPT) at 60°·s-1 and Ɵ were identified (P=≤0.05). Eccentric hamstring strength analysis on both the IKD and NordBord provide reliable information for practitioners, justifying their inclusion as one factor that may inform readiness to train and injury risk, within elite youth footballers. Although, careful consideration in relation to individual metrics must be given when informing decision making processes. Practitioners require clarity on the objectives of the assessment, what the strength metrics represent and how they provide insight into performance and injury risk.

Aim: To investigate the influence of muscle soreness on the speed of performing a motor reaction speed task in football goalkeepers. Methods: Twenty-four young healthy football goalkeepers, aged 1618 years old (average 16.7 ±0.67 year), with an average body height of 175.6 ±5.4 cm and body weight of 65 ±5 kg, participated in a study conducted during a 6-day training camp. The first day, referred to as day 0, was intended for initial tests and the following 5 days, referred to as days 15, consisted of training. On day 0, before the training period, anthropometric parameters such as weight and height were measured, subjects were questioned to determine the rate of perceived exertion (RPE) and perceived psychophysical readiness (PPR), a speed test with motor reaction choice (ST) was performed using a Smart Speed System and areas with muscle soreness (MS) were recorded by means of a computer tablet with the Navigate Pain application. The goalkeepers participated in two training sessions on each of the following 5 days. Before each training session, the same speed test was performed. Lap times for 5 m and 15 m were recorded. After the second training session each day, the participants drew digital pain maps using a computer tablet, marking separate areas of the body where they felt muscle soreness. These data were consolidated and the total area was analyzed to investigate if, throughout the training, there were any changes to the size of the area that was indicated as having MS. A categorization of body areas was also made to determine areas where muscle soreness was most frequently indicated. Each training session was monitored with heart rate (HR) registration and each goalkeeper determined his fatigue (RPE) and readiness to exercise (PPR) on a 110-point scale. Results: Twenty-three out of twenty-four (98.5%) goalkeepers indicated that they had MS during the study. Day 2 showed the highest incidence rate with 21 participants indicating that they felt MS. The biggest area of MS was also indicated on day 2, yet statistical analysis did not show significant differences in the area of MS between the training days. MS was most often indicated in the upper leg, i.e. the thighs. The average time of the first 5 m was 1.3 [s] (SD = 0.09), ranging from 1.28 [s] to 1.33 [s], while the average time of the following 10 m was 2.07 [s] (SD = 0.18), ranging from 2.04 to 2.1 [s]. The average total speed test time equaled 3.37 [s] (SD = 0.21), ranging from 3.33 to 3.38. Statistical analysis did not show significant differences in any of the results between the training days. Conclusions: Most of the goalkeepers felt muscle soreness as an effect of specific goalkeeper training, measured by indicating painful zones on digital pain drawings. In this study, where muscle soreness was induced by technical-tactical specific goalkeeper training, no significant changes were noticed in the speed of performing a motor speed test with reaction choice or on the area of muscle soreness indicated on digital pain drawings, although almost every goalkeeper had a large area of muscle soreness. Discussion: Many studies show that delayed onset muscle soreness (DOMS) causes a decrease in strength, power, range of motion and speed. However, in many cases, these studies are designed to induce high intensity DOMS and then conduct isolated motor skill tests. In this study the objective was not to induce high intensity DOMS but to investigate the effect of muscle pain, which is present naturally during training processes, and then assess its effect on a speed test which reflects real game situations – with a component of reaction choice and change of movement and direction. Approaching the subject from a different viewpoint allows us to see that the reliable assessment of the psychophysical state of players, made by observing their actions on the pitch or even using photocells to measure motion speed, is difficult without an insight into the parameters of soreness that players experience. These can be monitored, for example, through digital pain mapping software.

Trampoline flight time is a recent addition to Olympic scoring and was sufficient in weight to displace a formed medal winner from a podium placement at the 2012 Olympics. The aim of our study was to examine different warm-up routines on trampoline flight time. We examined ten elite, female trampolinists (mean ± SD: age 19.2 ±5.4 y) who performed six different warm-up routines in a randomised, cross-over, counter-balanced manner: (a) static stretching (STAT, control), (b) STAT+10 trampoline bounces, (c) dynamic stretching (DYN), (d) DYN+10 trampoline bounces, (e) DYN+Drop jumps (DYN+DJ) and (f) DYN+isometric mid-thigh pulls (DYN+IP). Data were analysed using general linear models, Dunnett-HSU post-hoc tests vs. Control/STAT and magnitude based inferences vs. control. Our analysis demonstrated that total flight time following DYN 10 (17.29 ±0.52s, 83% likely beneficial, P < 0.002) was significantly longer versus STAT (16.59 ±0.49 s), with a trend toward significance for DYN (16.97 ±0.20 s; 22% likely beneficial, P = 0.077). The DYN-IP (14.04 ± 0.48 s) and DYN-DJ (14.15 ±0.66 s) produced the shortest vs. all warm-up forms (P < 0.005). To the contrary, the DYN+DJ and DYN+IP conditions were >99% likely to be detrimental to performance. Our results demonstrate a clear improvement in flight times when using a dynamic warm-up coupled with a trampoline specific bouncing task (DYN+10).

Dietary nitrates have hemodynamic and metabolic effects on the body. This study aimed to investigate nitrate intake's effect on quadricep muscle oxygen saturation (StO2) of semi-professional soccer players during a repeated speed test (RSA). In a randomized, crossover design, 10 semi-professional soccer men players (21.3 ± 0.9yrs) performed two conditions: In one they consumed a nitrate-rich concentrated beetroot juice (250 mL/150 mg of NO3−) and in the other a placebo, 2h before a repeated sprint test. StO2 of the right vastus lateralis muscle was measured by near-infrared spectroscopy. A paired samples t-test was used to compute any differences in the subjects’ performance on the StO2 and on RSA test. The level of significance was set at p < 0.05. The supplementation of nitrates limited the decrease in muscle oxygenation during the six sprints of RSA test (p < 0.001) and also, there seemed to be a tendency for limited the decrement of performance on RSA test (t = -1.586, p = 0.157, η2 = 0.218). In conclusion, acute nitrate supplementation reduces the decrement of muscle oxygenation during exercise with repeated sprints and leads to a tendency of fatigue resistance during repeated sprints under controlled situations. Nitrate supplementation may have an ergogenic effect during exercise with repeated sprints via the higher muscle oxygenation.

Opis:
According to cytokine overtraining theory, skeletal muscle injuries are related to systemic inflammatory reaction. In response to inflammation, cells rapidly produce a series of proteins known as heat shock proteins (HSPs).These are considered to be molecular chaperones which play a universal role in maintaining cellular homeostasis. Among the subset of stress-responsive proteins, HSP27 and HSP70 are considered to be a new approach to monitoring exercise training and adaptive mechanisms. The study was designed to demonstrate the effect of sport training on changes in pro-inflammatory cytokines and HSPs, and their relation with muscle damage and body composition. Six elite canoeists (19.8 ±2.9 yr) were observed during preparatory training period (March) at the 1st, the 4th and after 7 days of the conditioning camp, and then after 3 days of recovery. The canoeing training did not induce muscle damage, decreased in IL-1β and HSP27, increased in TNFα and HSP70 concentrations. The highest changes in TNFα and HSP70 were observed 3 days after conditioning camp (during recovery) compared to initial level (the 1st day of conditioning camp). TNFα correlated with HSP27 (r = –0.563; P < 0.01) and HSP70 (r = 0.651; P < 0.001). Any significant changes in body composition were not observed. In conclusion, we could say that typical canoeing training improves cytokines and HSPs release, however, the changes are not related to muscle damage.

Aims and scope: Delayed Onset Muscle Soreness (DOMS) develops after intense physical activity and its mechanisms are due to inflammation. Kinesiology Taping (KT) improves microcirculation, supports myofascial functions and relieves the tissue. The aim of this study was to verify whether KT has an analgesic action in the DOMS and whether somatotype is associated with this action. Materials and Methods: There were 20 healthy subjects aged 27.7 ±6.4 years with moderate or high physical activity included into the study. The training with emphasis on eccentric muscle work was performed. Somatotype of respondents was assessed by Heath-Carter method. While DOMS occurred, KT muscle application on one of the limbs was done. For the next five days subjects filled out questionnaires in which they served intensity of pain on the basis of Visual Analogue Scale (VAS). Results and conclusions: In the limb where KT application was used a significant (p < 0.05) reduction in the intensity of DOMS compared to the limb without application was observed. It was found that the somatotype has no effect on the reduction of DOMS (p > 0.05). Conclusions: KT exhibits analgesic properties in DOMS. Somatotype has no relation to the effectiveness of KT analgesic efficacy in DOMS.

Objective: To assess current literature focused on the influence of functional training with blood flow restriction (BFR) on muscular adaptation in adults below the age of 65 years. Methods: A systematic literature search was performed with the following databases: PubMed, CINAHL Complete EBSCOhost, and ScienceDirect. Two researchers filtered the articles according to the criteria and quality, supported by the Consolidated Standards of Reporting Trials (CONSORT) tool. Studies were limited to those with participants with a mean age between18 and 65 years. Articles were peer-reviewed, available in English, and utilized either multi-joint resistance exercises or functional exercise as the intervention. Results: The search yielded 16 studies on uninjured, older adult, injured and athletic subjects. Regardless of the population, the studies tended to favor BFR training for improvements of strength, but this was highly dependent on cuff pressure and training load. Conclusions: Current literature suggests that BFR with functional and or multi-joint strength training is successful in improving strength, hypertrophy, function and in pain reduction. Favorable results with functional BFR included procedures using relative and well-controlled occlusion pressure. More research is necessary to understand the effect of BFR on self-reported outcomes and hypertrophy in athletic and older adults.

The purpose of this study was to determine if physical activity of different intensity has an effect on reduction of delayed onset muscle soreness. Eighty women divided into two groups participated in the study. Subjects from Group 1 participated in the training of upper libs, whereas subjects from group 2 – in the training of lower limbs. Tests of power of upper limbs – the active overhang on the bar (Gr. 1) and power of lower limbs – the vertical jump test (Gr. 2), visual analog scale of pain (VAS) and the International Physical Activity Questionnaire (IPAQ) were used as investigative tools. The majority of studied women were characterized by the high level of physical activity. Physical activity level had strong positive correlation (r = 0.54; p < 0.001) with the reduction of pain. Taking into account the partition according to the kind of physical activity, there was observed some significant correlation between the diminution of delayed onset muscle soreness and the level of moderate activity and walking (relocating). Physical activity level positively correlated with the reduction of delayed onset muscle soreness. Moderate physical activity and walking proved to be the most beneficial from the reduction of delayed onset muscle soreness point of view.

Opis:
Sprint cycling events require a high level of anaerobic capacity and, therefore, may affect peripheral fatigue throughout exercise-induced muscle damage. In fact, those alterations might decrease power generation. This study was performed on a 23 years old male elite track cyclist taking part in a sprint event. The measurements included power output (W) and cadence (rpm), lactate concentration (La-), heart rate (bpm), Rating of Perceived Exertion scale and viscoelastic properties analysis. The present study has shown a new approach to monitor the muscle properties of the lower extremity after 200 m flying start and repeated sprint races. Therefore, we hypothesized that repeated sprint races might lead to alterations in viscoelastic properties of lower extremity muscles. In track cycling, especially in sprint events, these variations may lead to increased muscle fatigue. Furthermore, training control and monitoring related to the assessment of muscles properties can be a source of counteracting injuries and relieving fatigue.

The low achievement of long jump athletes and the limited virtual-based aquatic plyometric exercises to increase lower extremity muscle strength are the gaps in this study. This study aims to increase lower extremity muscle strength of long jump athletes through virtual-based plyometric aquatic training. This research adopted a mixed methods research. This study involved participants from long jump athletes at the University of Tanjung Pura in Indonesia (n = 20). Participants were divided into two groups, namely an experimental group (n = 10) and control group (n = 10). The quantitative instrument involved a leg dynamometer for measuring lower extremity muscle strength. While, the qualitative instrument used in-depth interview. Quantitative data analysis was carried out through IBM SPSS to calculate descriptive statistics and normality, while the paired sample t-test to test differences in lower extremity muscle strength values in the experimental and control groups. Qualitative analysis was carried out through recording, describing and coding stages, which categorized into three themes. Based on quantitative results, it showed that virtual-based plyometric aquatic training was proven significantly increase lower extremity muscle strength (ps0.05), but there was no significant effect in the control group (p & 0.05). Qualitative results found out that most of the participants gave a positive opinion regarding virtual-based plyometric aquatics. Thus, this study confirms that virtual-based plyometric aquatic training can be used to increase lower extremity muscle strength.

Opis:
Being injured is inherent to participating in football activities; therefore, prevention of injuries is crucial. This requires that the risk factors for injury be established. However, such studies are rarely conducted in women athletes in Africa. The study’s aim was to explore intrinsic risk factors for injury among African women football players using functional and musculoskeletal assessments. Participants (n=40) completed demographic questionnaires; upper and lower limb active range of motion (AROM); muscle endurance and functional movement screening (FMS™) assessed. Median age [Q1; Q3] was 24 [20; 27] years. Participants performed 20.5 [0; 30.5] push-ups and 28 squats [30; 38] in 60s; and held the prone elbow plank for 46.2s [30.6; 64.5]. Median FMS™ score was 12 [10; 13]; most players (n=27, 68%) could not execute a proper deep squat. Most players (70%; n=28), were able to properly perform the in line lunge but scored poorly in the shoulder mobility domain of the FMS™, with 73% (n=29) scoring ≤1. Players with a history of injury had lower FMS™ total (p=0.02). Overall, participants presented with low muscle endurance and movement imbalances, which might predispose them to injury. Hence, strength and conditioning measures should be instituted in this population to prevent injuries.

Opis:
Rationale and objective of the study: In the study of coordination of motor abilities, motor performance tests without examining the internal structure of the movement were used. The objective of this study was to examine the kinesthetic differentiation capacity level and to stimulate muscles during a test among basketball players in intermediate and specialist stages of training. Material and methods: Among ten basketball players from two equal groups at different level of advancement in sport, who play at different positions on the field, kinesthetic differentiation capacity was assessed by the „Basketball shooting with different balls” test. In order to assess the muscle involvement during the test, they were connected to the EMG amplifier. Results: More advanced basketball players obtained better results in the test, by an average of 7.4 point out of 60. Tested muscle bioelectric tension was lower by 21.8% in advanced players and the difference in the non-dominant hand was as high as 34.6%. Conclusions: The research indicates that advanced players obtain better level of kinesthetic differentiation and their average muscle bioelectric tension during throws is lower compared to beginner players. The difference in bio-electrical muscle tension in the time of throwing different balls was smaller in basketball players who are more advanced in training, and in both groups in the dominant hand. Mean values of EMG signal in a selected time interval show greater variability among the more advanced players.
