Breast Injury During Sport Participation

Laura J Smith, Tamara Eichelberger, Elizabeth Miller and Edward J Kane

Article Type: December 26, 2018 | Indexed Archive: Volume 4

A recent study found that almost half (47.9%), of female college athletes participating in basketball, soccer, volleyball and softball (n = 194) suffered a breast injury during their college career with less than 10% reporting their injury to health personnel with only 2.1% receiving treatment. Breast injury in female athletes is under-reported and is lacking a much-needed level of awareness in sport. If there is a void in awareness of breast injuries and in reporting breast injuries, preventive...

Effect of Blood Flow Restriction Training in Combination with a High-Intensity Interval Training on Physical Performance

Alexander Torpel, Marie Brennicke, Maximilian Kuck, Tom Behrendt and Lutz Schega

Article Type: Research Article | Indexed Archive: Volume 4

We aimed to investigate whether a Blood Flow Restriction Training (BFR) prior to a High Intensity Interval Training (HIIT) leads to a higher increase in physical performance than a sole HIIT. 24 male participants (18 to 30 years) were randomly assigned to a BFR+HIIT or HIIT group which performed 3 times per week over 4 weeks a HIIT on bicycle-ergometers. Prior to each training session of the HIIT, both groups carried out 4 sets of deep squats without additional load but the BFR+HIIT group perfor...

Isokinetic Force and Work Capacity after Long-Duration Station «MIR» and Short-Term International Space Station Missions

Yuri A Koryak

Article Type: Research Article | Indexed Archive: Volume 4

The effects of long-duration (~ 210 days) aboard the Orbital Station "MIR" and short-term (~ 10 days) spaceflights aboard the International Space Station on the joint torques of various muscles and work capacity of knee extensors were studied in male cosmonauts. Greater postflight changes in maximal joint torque were observed for back, knee, and ankle extensors compared with flexors, and the difference was especially clearly seen after long-term spaceflights. Muscle work capacity was inferred fr...

Extremely Low HDL Cholesterol and Increased LDL Cholesterol Induced by the use of Anabolic Steroids in a Body Builder: A Case Study

Min Li and Simon W Rabkin

Article Type: Case Report | Indexed Archive: Volume 4

Anabolic steroids are banned substances in competitive sports because they are an exogenous method for performance enhancement in sports that require increased muscle mass or strength. However, these agents are still used by certain athletes who wish to accelerate the increase skeletal muscle mass with exercise. The adverse effect of anabolic steroids on High-Density Lipoprotein Cholesterol (HDL-C) and Low-Density Lipoprotein Cholesterol (LDL-C) has been explored in case control studies comparin...

The Effect of Core Exercise Program on Motoric Skills in Young People

Yildiz Yaprak

Article Type: Research Article | Indexed Archive: Volume 4

The objective of this study was to determine the effects of an 8-week core exercise programme performed on Swiss ball and BOSU ball that on dynamic balance, flexibility, spinal Range of Motion (ROM), back muscle endurance, back muscle strength, abdominal muscle strength, and body composition for healthy young males. The present findings show that there were significant increases between pre and post-training values for back muscle strength, abdominal muscle strength, spinal ROM and dynamic bala...

Within-Day Energy Balance in Mexican Female Soccer (Football) Players - An Exploratory Investigation

Francisco Arroyo, Dan Benardot and Elizabeth Hernandez

Article Type: Research Article | Indexed Archive: Volume 4

To assure optimal performance and reduced risk of illness and injury, athletes require a food and fluid intake that optimally satisfies normal physiological requirements plus the additional demands of physical activity. Both macronutrient (i.e., carbohydrate, fat, and protein) and micronutrient (i.e., vitamins and minerals) intakes are essential for maintaining health, optimal body composition, and the desired athletic performance ....

Physical Activity in the Prevention of Abdominal Obesity: Type, Duration and Intensity

Francisco Jose Gondim Pitanga, Cristiano Penas Seara Pitanga and Carmem Cristina Beck

Article Type: Opinion | Indexed Archive: Volume 4

To suggest the type and dose (duration and intensity) of physical activity more adequate to prevent abdominal fat in adults. The evidences that were presented are part of studies on physical activity and abdominal fat published in the national and international literature. Physical activity (aerobic and resistance exercises), with a prolonged duration of moderate intensity for men and walking or moderate intensity for women, is suggested as the most adequate for the prevention/treatment of abdom...

Effects of an Intense One-Week Skiing Program on Balance Abilities in Pediatric Cancer Patients

Kurpiers N, Vogler T and Flohr S

Article Type: Research Article | Indexed Archive: Volume 4

Beside a number of physical, physiological, psychological, and social impairments, cancer and its treatment can also reduce balance abilities. The aim of the present study was to assess the effect of a one-week winter camp with an intense alpine skiing program on balance ability of pediatric cancer patients in the follow-up care. Eighteen pediatric cancer patients. Most studies on the effects of physical activity on cancer have been conducted on adults. Much less research has been done in pediat...

Proximal Hamstring Injuries: An Unusual Finding

Raj Subbu and Fares Haddad

Article Type: Case Report | Indexed Archive: Volume 4

The proximal hamstring complex is frequently injured in athletes, traditionally occurring in waterskiing, sprinting and hurdles. However, more recently it is increasingly being reported in a variety of different sports. The hip and knee joint are stabilized by the hamstring muscles due to eccentric contractions, which occur when a muscle contracts whilst passively stretched. This happens to the hamstring muscle during hip flexion and knee extension. Injuries are much more common during eccentric...
