Investigating Player Selection within UK Academy Soccer: The Application of Objective and Subjective Assessments in Detecting Talent
Full text linkTalent selection and development in academy soccer is highly dependent on coach intuition. Given such reliance upon subjective inputs, a greater understanding towards the utility of coach intuition may prove invaluable. The present study investigated coach agreement, the associations between subjective and objective outcomes and prominent traits highlighted within player (de)selection. Academy players (n = 45, age = 14 ± 2yrs) and coaches (n = 10, age = 31 ± 5yrs) were recruited from a professional soccer academy. Objective assessments included tactical and psychological surveys, physical assessments (linear sprints, change of direction and jumping tasks) and performance analysis (performance assessment for team sports). Coach subjective player gradings were collected using a visual analogue scale aligned to the objective assessments. Lead and assistant coaches demonstrated poor-to-moderate agreements in perceived player skills (ICC = 0.48 to 0.76) and fair to almost perfect agreement in player (de)selection (ICC= 0.23-1.00, P <.001 to .26). However, coach agreement reduced as players aged. Likewise, a maturation related bias was present whereby biologically older players were selected over their lesser mature players. Moreover, coach intuition demonstrated a strong predictive capability to select players, whilst the study was incapable of distinguishing exclusive traits related to selection outcome
The Physiological and Morphological Benefits of Shadowboxing
Full text linkIs shadowboxing an effective form of functional exercise? What physiological and morphological changes result from an exercise program based exclusively on shadowboxing for 3 weeks? To date, no empirical research has focused specifically on addressing these questions. Since mixed martial arts (MMA) is the fastest growing sport in the world, and since boxing and kickboxing fitness classes are among the most popular in gyms and fitness clubs worldwide, the lack of research on shadowboxing and martial arts-based fitness programs in the extant literature is a shortcoming that the present article aims to address. This case study involved a previously sedentary individual engaging in an exercise program based exclusively on shadowboxing for 3 weeks. Body composition and heart rate data were collected before, throughout, and upon completion of the 3-week exercise program to determine the effectiveness of shadowboxing for functional fitness purposes. An original shadowboxing program prepared by an Everlast Master Instructor and NASM Certified Personal Trainer (NASM-CPT) and Performance Enhancement Specialist (NASM-PES) was used for this 3-week period. The original shadowboxing program with goals, techniques, and combinations to work on throughout the 3-week program is included in this article. This case study demonstrates that a 3-week exercise program based exclusively on shadowboxing can increase aerobic capacity, muscle mass, bone mass, basal metabolic rate, and daily calorie intake, and decrease resting heart rate, fat mass, body fat percentage, and visceral fat rating in a previously sedentary individual. The results of this research demonstrate that shadowboxing can be a safe and effective form of exercise leading to morphological and physiological improvements including fat loss and increased aerobic capacity. The results of this research also demonstrate that the Tanita BC-1500 is a reliable tool for individuals to evaluate their own fitness progress over time
The Physiological and Perceived Impact of Wearing a Face Mask During Maximal Exercise
Full text linkThe COVID-19 pandemic prompted the expectation of facemasks in fitness facilities during exercise. However, the physiological and perceptual responses of wearing a facemask during exercise has not been fully investigated. The purpose of this study was to determine the effect of facemasks on selected physiological and subjective variables during exercise. Using a crossover design, males (n =8) and females (n=7) and were randomly assigned to (1) a surgical facemask, (2) a cloth face mask, and (3) no mask and completed Bruce Protocol maximal graded treadmill tests 48 hrs apart. Collected data included heart rate (HR), oxyhemoglobin saturation (SpO2), rating of perceived dyspnea (DYS), perceived rate of exertion (RPE) and time to exhaustion (TTE). No significant (p>0.05) differences were found for HR or SpO2 at any of the treadmill stages. DYS was higher with both masks compared to no mask, but only significant (p < 0.05) between the cloth and no mask conditions in stages 2 and 3. RPE was greater in both mask conditions compared to no masks, but only significantly greater between the cloth mask and no mask conditions in stage 3. No significant differences were found for TTE among the conditions. Wearing face masks during exercise and has little effect on HR, SpO2, or TTE. However, facemasks may negatively influence DYS and RPE contributing to feelings of exhaustion. Participants should be made aware that the discomfort of wearing a mask during exercise will not hamper performance
HIIT and Resistance Training Effects on Learning-related Outcomes in Underserved School Children
Full text linkResearch has demonstrated associations between differing modalities of physical activity (PA) and behavioral and learning outcomes; however, little evidence exists in real world settings. To evaluate the effects of embedding high intensity interval training (HITT) and resistance training (RT) into physical education (PE) curriculum on PA, academic performance, and behavior in youth attending urban schools. Forty boys and 30 girls; ages 8-10 yrs. enrolled in an expanded public school supplemental learning program were assigned into one of three conditions using a pragmatic trial design: standard PE curriculum (n = 23), HITT (n = 25), and RT (n = 22). PA was measured using accelerometers; math achievement scores were conducted at baseline and post-intervention using the Math Knowledge Assessment (MKA); behavior was assessed using the Abbreviated Conners Rating Scale (ACRS) daily. Participation in HITT resulted in 1.86 additional vigorous PA minutes (p=0.04) and 0.76 additional very vigorous PA minutes (P=0.02) per session, but was not associated with increased moderate PA minutes compared to the control group. RT PA outcomes did not differ from regular PE. Participating in HIIT, but not RT, was associated with a 1.82-point improvement in math test scores compared to those in the same grade in the standard PE group (p=0.02). No group assignment was associated with behavioral ratings. Embedding HITT within PE has potential for improving vigorous PA levels and may affect learning outcomes in urban youth. This is consistent with prior studies which show how short bouts of intense exercise can improve cognitive outcomes
Evidencing the Need to Broaden the Position of Trust Legislation to Include Sports Coaches
Full text linkWhen an individual is in a position of trust over another person, the age of consent is raised from 16 to 18 in the United Kingdom. Currently, the definition of a Position of Trust is restricted to professions such as teachers, care workers and youth justice workers. Recent high-profile cases have contributed to a growing consensus amongst key stakeholders of the need to broaden this legislation to include other roles, such as a sports coach. This study represents the first investigation into the number of concerns recorded by local authorities across England and Wales regarding sexual relationships between a person who is in a potential Position of Trust which is not currently covered by the legislation and someone who was aged 16 or 17 years old. Freedom of Information Requests resulted in full responses from 142 out of the 172 local authorities. A total of 653 cases were recorded over a 4-year period. The most prevalent of the identified roles were related to sport, however, roles related to religion, youth work, transport and uniform services were also cited. Regional differences regarding the number of cases recorded are highlighted and the implications of these findings are discussed
Can Physical Fitness Performance be Used to Predict the BMI Status of First-Year Students? A Case Study from a University in Southern Taiwan
Full text linkThis study aims to investigate the relationship between the physical fitness performance of college freshmen and the BMI body weight status (normal/ abnormal). We conducted case studies and obtained data on 7,160 participants aged 18 years from a university in southern Taiwan. All participants completed four physical fitness tests (seated forward bench, standing long jump, sit-ups, and cardiorespiratory endurance) and BMI assessments with the professional assistance of PE teachers. BMI is used to define the normal and abnormal state of body weight. Logistic regression analysis was used in this study. The results show that the four physical fitness tests currently implemented in college physical education can be used to predict whether the weight of the freshmen is normal. Cardiorespiratory endurance seems to be the most important feature for predicting the type of BMI (normal/abnormal), whether male or female. When the "cardiorespiratory endurance" of freshman students increases by a category, the probability of males belonging to the healthy weight category increases by 4.879 times, and the probability of females increases by 2.927 times. This study provides a new perspective for predicting whether the freshman's body weight is normal or not by using different types of college physical fitness test performance
Differences in Temporal Gait Parameters When Walking on Even Surface Walkway, Treadmill, and Pushing a Constant Resistant Sled
Full text linkMotorized treadmills and weighted sleds are employed in clinical settings to improve lower extremity strength, power, and endurance. However, little is known about how the spatio-temporal parameters compare when walking on an even surface walkway, walking on a treadmill, or pushing a sled. This study aimed to examine the variations in spatial and temporal gait parameters when walking on an even surface walkway (EW), on a treadmill (TW), and while pushing a sled (SP). Forty healthy subjects participated in this pilot study. The mean age and BMI of all participants were 24.39 (± 2.86) years and 68.26 (± 13.92) kg/m^2, respectively. Spatio-temporal parameters were gathered using the Mobility Lab ADPM software and six sensors containing accelerometers and gyroscopes. Participants were directed to walk at a normal and comfortable speed for 7 m on an even surface walkway for two trials. Next, the subjects walked on the treadmill for two trials at a speed based on age. For males aged <30 and females 20-40 years of age, the speed was 1.3 m/s. While for males aged 30 or older, the speed was set to 1.4 m/s. Finally, participants were instructed to walk at their normal pace while pushing a 60 lb sled for 9.1 meters (m). Treadmill walking provoked a significant increase in temporal variables, whereas pushing a sled significantly reduced the temporal variables. Treadmill walking resulted in a decrease in double limb support time and an increase in single-limb support time compared with even surface walking. Although cadence was greater when walking on a treadmill versus an even surface walkway, the difference may be attributed to a fixed speed on the treadmill, which was determined by age. Treadmill gait training is recommended for subjects that could benefit from an increase single limb support time to improve dynamic balance such as Parkinson patients. On the other hand, for those participants that dynamic activities are challenging, such as concussion and vestibular patients, pushing the sled will slow down gait parameters allowing gait training with an added resistance benefit. Finally, it has been proposed that further investigation should focus on the differences in lower extremity muscle activation and recruitment patterns under various walking conditions
Advocating for and Providing Quality Adaptive Physical Education
Full text linkIdeally, as put across by the Disability & Human Rights guide, the Convention on the Rights of Persons with Disabilities (CRPD) does not give a detailed description of disability but rather gives a wide range of features that intend describe disability. The truth is, despite being incapacitated in a certain way, people living with disabilities should be given the same opportunities as those without. Our separate literature analysis discovered that different efforts had been put in place to present equal opportunities for people living with disabilities. One of these efforts is adaptive physical education. As its name suggests, adaptive physical education is a physical education that has been adapted to create equal opportunities for persons with disabilities as it is for people without disabilities. To this effect, this paper and its entirety will focus on presenting the different themes observed from the different pieces of literature separately
Effects of a Respiratory Resistance Mask on Forced Expiratory Volume at 1s (FEV1), Forced Vital Capacity (FVC) and the Ratio of FEV1/FVC Lung Function following High Intensity Training (HIT)
Full text linkTraining masks (TMs), marketed as simulated altitude training devices, suggest increased workout capacity, intensity tolerance and recovery. The claim is that the training mask improves respiratory power and breathing mechanics by strengthening the respiratory muscles through breathing resistance provided by the TM. The aim of this study was to compare the effects of a commercially manufactured TM in conjunction with bicycle ergometry, high intensity training (HIT) on selected lung function parameters. Volunteers (N=16) participated in this study and were randomly assigned to an experimental or control group. The experimental group wore the TM with progressive increased respiratory resistance and the control group wore the TM with no respiratory resistance. To determine lung function, pre- and post-test assessments consisted of forced expiratory volume at 1s (FEV1), forced vital capacity (FVC), the ratio of FEV1/FVC. Additionally, to determine the TMs effectiveness of maximal oxygen consumption pre- and post-time to failure during a maximum treadmill test was performed. Training was completed on a cycle ergometer on 3d/wk for 4 wks. Participants exercised at 85% of HRmax with a pedal rate of 100-120 rpm at individually set resistance levels. Training sessions consisted of 10 bouts of 30s exercise followed by 30s of active recovery for a total time of 10 minutes. The respiratory resistance for the experimental group progressively increased over the training period. Repeated measures ANOVAs yielded significant between group difference in FVC (p = 0.02) but not for FEV1 or maximum treadmill time. In conclusion, TMs in combination with HIT failed to improve lung function but created sufficient resistance to strengthen the muscles in respiratory ventilation
Physical Activity in Pregnancy was Favorably Associated with Maternal And Offspring Health Indices
Full text linkRegular physical activity (PA) in pregnancy can benefit the pregnant woman through a shorter birth and a shorter recovery period. The study aimed to investigate the effect of PA in pregnancy, on maternal and offspring health indicators. Population-based data were obtained from a national database that included anthropometric and physical fitness data of almost all Greek children 8 to 9 years. Α random sample of 5,125 dyads of mothers-children was evaluated. Telephone interviews were carried out with the use of a standardized questionnaire for the collection of maternal lifestyle factors. Children born to mothers who participated in the recommended PA levels had lower odds (OR=0.78, 95% CI: 0.69-0.95) to be overweight/obese in childhood. Adequate PA levels in pregnancy were found to be associated with lower odds of preterm birth by 61% (OR = 0.39, 95% CI: 0.17-0.87), and alcohol consumption in pregnancy by 62% (OR = 0.38, 95% CI: 0.27-0.56) as compared to the inadequate level of PA. Also, mothers with adequate PA in pregnancy had decreased odds for excessive GWG and final BMI by almost 40% in comparison to those with inadequate PA levels. PA in pregnancy does seem to be related to offspring health indicators (e.g. obesity at 8 years) and is associated with a more favorable maternal health profile
