Increases in Upper-Body Strength are Dependent on Training Modality and Independent of Initial Strength Level and Fat-Free Mass Index in Women

Monica L Hunter, Jana L Arabas, Liz Jorn, Jerry L Mayhew and William F Brechue

Article Type: Research Article | First Published: 2024/07/07

Strength was determined from one-repetition maximum (1RM) free weight and modality specific upper-body press measured before and after 12 weeks of periodized RT with each modality. From a large cohort (N = 570), the top and bottom 20% were identified for one-repetition maximum bench press with free weights (FW, n = 60), seated horizontal press (SHP, n = 80), and supine vertical press (SVP, n = 87) for low (n = 94) or high (n = 133) FFMI (FFMI = FFM/Ht2) groups. RT also included upper- and lower-...

Comparative Review of Literature for Post-Operative care- Anterior Cruciate Ligament surgical type: Bone-Patellar-Bone and Semitendinosus Autografts

Felicity Davies, Alexander T. McDaniel, Lindsey H. Schroeder, Angila Berni, Daniel Cobble and Carolina Priester

Article Type: Review Article | First Published: 2024/05/19

The two most common autografts for anterior cruciate ligament (ACL) reconstruction (ACLR) are bone-patellar tendon-bone (BPB) and semitendinosus-gracilis (STG). There is currently no consensus on the optimal graft choice. The type of graft chosen for ACLR is often made by the physician with minimal input from the patient. The primary aim of this study was to review the current literature and examine differences in post-operative care, time to discharge, and clinical outcomes between the two proc...

Resistance Exercise Order Does Not Affect Training Intensity in Middle Aged and Older Women

Ágatha Graça, Alex Silva Ribeiro, Wendell Arthur Lopes, Arthur Garcia de Sales, Higor Santos Fonseca, Jerry L. Mayhew and Matheus Amarante do Nascimento

Article Type: Original Article | First Published: 2024/04/27

The aim of this study was to analyze the effects of different resistance exercise orders on training intensity in middle-aged and older women. Twenty-three participants (age 50-78 years) were randomized into two RT groups: One group started training sessions performing multi-joint exercises followed by single-joint exercises (MS, n = 12; 58.92 ± 5.53 years), while the other group performed their session in the opposite order (SM, n = 11; 57.93 ± 11.89 years). Both groups completed RT sessions ...

Enhancing Precision Nutrition: Investigating the Interplay of Breath Acetone and Body Composition in Division I Athletes

Allyn Abadie and José R Fernández

Article Type: Original Research | First Published: 2024/04/29

Precision nutrition requires the discovery and understanding of quantitative biomarkers with sufficient between person variability. In healthy individuals, glucose is used as the preferential energy substrate and is not readily stored. Circumstances such as disease, fasting, or injury, can cause glucose to be unable to be used or not readily available. In these circumstances the body can utilize alternative energy sources such as ketones derived from stored fatty acids....

Exercise Induced Changes in the Appearance of Circulating Microvesicles

Amit Bandyopadhyay and Nabanita Ghosh

Article Type: Review Article | First Published: 2024/02/05

Extracellular vesicles (EV) are small membrane bound vesicles which are capable of delivering biomolecules to neighbouring recipient cells or more distant cells, where they induce various signalling cascades and subsequently alter their metabolism. These EVs may include apoptotic bodies, microvesicles, and exosomes, which have emerged as important mediators of cell to cell communication in normal physiology and pathological status. ...

The Relationship between VO2 max and 1200m Shuttle Run Performance in Elite Academy Football Players

Ronan Kavanagh, Kevin McDaid, David Rhodes, Mark Connor, Rafael Oliveira, Ian Varley and Ryland Morgans

Article Type: Original Article | First Published: 2023/12/08

Seventeen male professional outfield football players completed a laboratory based incremental treadmill test to establish vVO2max and a field based 1200m shuttle test to estimate velocity at MAS. During the pre-season period a linear speed phase consisting of twice weekly PS exposures were conducted and each player’s PS reached during this period was established. Body composition was measured using DEXA....

Impact of the Prophylactic Brace on Knee Kinematics and Stability in Dynamic Situations

Romain Julien, Arfaoui A and William Bertucci

Article Type: Research Article | First Published: 2023/12/07

Prophylactic braces are commonly utilized protective devices in sports to reduce the risk of knee injuries. Despite their widespread use, there exists a divergence of opinions regarding their effectiveness. Several studies have investigated the efficacy of prophylactic brace in athletes, revealing enhancements in biomechanical factors linked to the risk of anterior cruciate ligament injuries, such as knee range of motion, flexion angles, or angular velocity....

Article Type: Case Study | First Published: 2023/11/19

Long COVID has recently been recognized by the World Health Organization as a syndrome occurring two months after infection with Covid-19 with various physical, neurocognitive, and psychiatric symptoms that cannot be explained by another diagnosis. It is estimated that between six and twenty million patients in the United States alone are affected by this condition....

A cross-sectional, quantitative study was conducted with 286 mothers of preschool children aged 2-6 years. Data were collected via a Google Forms questionnaire, distributed through WhatsApp groups and social networks, following a Snowball sampling model. The questionnaire addressed socioeconomic data, daily physical activity (PA), and sedentary behavior (SB), particularly screen time (ST). Statistical analysis was conducted using STATA SE with the t-test for the means of two samples with equal v...

Injury Incidence and Burden in 979 Player Seasons of an Elite Dutch Soccer Academy

Danny Holtus, BSc, Johannes L Tol, MD, PhD, Bastiaan Bruning, PT, Lotte Jagtman, MSc, Vosse de Boode, PT, MSc and Gustaaf Reurink, MD, PhD

Article Type: Original Article | First Published: 2023/04/05

The epidemiology of injuries in youth soccer is ambiguous. Most studies are based on the consensus statement of Fuller, et al. where pediatric-specific injuries are not included. As a result, this type of injury is often neglected or categorized inconsistently. A consequence may be adhering an incorrect focus in injury prevention. This study aimed to describe injury incidence, severity and burden by age group in an elite soccer academy....

Yang Yang, Cao Youxiang, Chen Jiacheng, Hu Guangxuan, Chang Bo and Yi Xuejie

Article Type: Review Article | First Published: 2023/07/19

Previous studies have shown that High-Intensity Interval Training (HIIT) is effective in improving maximal oxygen uptake, blood pressure, and physical health-related indicators in older adults. However, whether HIIT is more effective in improving cardiorespiratory fitness and exercise capacity in older adults compared with Moderate-Intensity Continuous Exercise (MICT) remains controversial. ...
