Extended Range Of Motion Does Not Induce Greater Muscle Damage Than Conventional Range Of Motion In The Bench Press Exercise, Patryk Matykiewicz, Michał Krzysztofik, Adam Zając
Baltic Journal of Health and Physical Activity
Introduction: Range of motion (ROM) of resistance exercise affects the muscle damage magnitude and the recovery-time course. Thus, the main aim of this study was to compare conventional and extended ROM in the bench press exercise on neuromuscular fatigue assessed by velocity changes during bench press throw, as well on the exercise-induced muscle damage evaluated by creatine kinase (CK) activity in the blood. Material and Methods: A total of fourteen healthy, well-trained males performed 5 sets of the bench press exercise at 70% of one repetition maximum with either standard (STD) and cambered (CMB) barbell until reaching volitional failure. CK …

The Effects Of Whole-Body Hot Water Immersion After Exercise Induced Muscle Damage On Exercise Performance And Inflammatory Markers, Rogelio A. Realzola
Health, Exercise, and Sports Sciences ETDs
This study examined the effects of hot water immersion (HWI) on exercise performance and inflammatory markers after a resistance exercise-induced muscle damage protocol. Strength trained males (n = 5) and females (n = 5) completed two experimental trials separated by at least 2 weeks in a randomized crossover design; one trial involved HWI, the other temperate water immersion (TWI). For each trial, subjects performed a muscle damaging protocol followed by HWI or TWI for up to 50 minutes. The protocol consisted of 10 sets of 8 repetitions at 70% of 1-repetition maximum with 4s eccentric, 1s concentric lifting …

To examine the contralateral repeated bout effect (CL-RBE) on muscle damage markers and motor unit (MU) control strategies, seventeen healthy adults performed two bouts of 60 eccentric contractions with elbow flexor (EF group; n = 9) or index finger abductor (IA group; n = 8) muscles, separated by 1 week. All participants randomly performed eccentric exercise on either the right or left arm or hand muscles, and muscle damage markers and submaximal trapezoid contraction tests were conducted pre, post, 1- and 2-day post eccentric protocol. One week after the first bout, the same exercise protocol and measurements were performed on …

The Effects Of Cannabidiol Supplementation On Measures Of Performance And Fatigue Following Eccentric Exercise, Brett Crossland, Nicholas A. Levine, Cayla Clark, Kyndall Ramirez, Nicole Varone, Julio Sanchez, Anthony A. Duplanty, Brandon R. Rigby
International Journal of Exercise Science: Conference Proceedings
Following intense exercise, there is a period of time where performance is decreased. This period of reduced performance is characterized by several factors including myofibrillar disruption, reduced range-of-motion, inflammation, and an influx of enzymes and proteins. Cannabidiol (CBD) has been marketed as a recovery supplement capable of reducing markers of fatigue and inflammation following exercise, yet this claim has not been investigated. PURPOSE: The purpose of this study was to determine if CBD supplementation limits fatigue and expedites a return to performance following intense eccentric exercise. METHODS: A double-blind, crossover design with repeated measures was used. Twenty-four NCAA …

Repeated bout effect (RBE) describes a phenomenon that an initial unaccustomed eccentric exercise (ECC) bout can confer a protective effect against muscle damage from the subsequent same exercise. This protection has been observed in the same muscle, as well as the contralateral homologous (CL-RBE) muscle. But it is unknown whether the RBE is evident for non-local unrelated heterogonous muscles. The purpose of this study was to examine whether an initial elbow flexion (EF) muscle-damaging ECC could confer RBE against muscle damage from the subsequent ECC performed in the remote lower limb knee flexor (KF) muscle group. Twenty-seven young individuals were …
An Examination Of Acute Cross-Over Effects Following Unilateral Low Intensity Concentric And Eccentric Exercise, William Miller, Sunggun Jeon, Xin Ye

We compared the effects of low intensity concentric (CON) and eccentric (ECC) exercise on the force and neural responses of the dominant (exercised) elbow flexors (EFs), and studied if these conditions could induce cross-over effects to the contralateral (non-exercised) EFs. Fifteen subjects (8 males) completed all conditions (CON and ECC: 6 sets of low intensity exercise to failure; control: rest) in separate visits with a randomized order. Maximal isometric force and electromyography (EMG) of the dominant and contralateral EFs were assessed at pre, immediate-, 24-, and 48-h-post. Two-factor (condition and time) linear mixed-model analyses were performed to examine the force …
Ubiquitin Proteasome System Activity Is Suppressed By Curcumin Following Exercise-Induced Muscle Damage In Human Skeletal Muscle, Thomas D. Cardaci, Steven B. Machek, Dylan T. Wilburn, Paul S. Hwang, Darryn Willoughby Phd

International Journal of Exercise Science: Conference Proceedings
PURPOSE: Curcumin is a natural polyphenolic compound with antioxidant and anti-inflammatory properties. In vitro and in vivo animal studies have demonstrated that exposure to curcumin leads to dysregulation of the ubiquitin-proteasome system (UPS). However, to date, no study has investigated curcumin’s ability to influence UPS activity in a human model. Therefore, the purpose of this study was to investigate the effects of curcumin supplementation on markers of UPS activity in the presence of elevations in UPS activity due to exercise-induced muscle damage. METHODS: Twenty-three recreationally active male and female participants between the ages of 18-30 were randomized into …
Curcumin And Boswellia Serrata Supplementation Result In Reduced Inflammation Following Eccentric Leg Press Exercise, Asheal A. Davis, Elizabeth A. Tanner, Melody A. Gary, Brian K. Mcfarlin
Curcumin And Boswellia Serrata Supplementation Result In Reduced Inflammation Following Eccentric Leg Press Exercise, Asheal A. Davis, Elizabeth A. Tanner, Melody A. Gary, Brian K. Mcfarlin
International Journal of Exercise Science: Conference Proceedings
Repetitive exercise on consecutive days is a key component of many long-term training plans. This type of exercise results in muscle inflammation and soreness that limits the capacity to sustain exercise at a high effort. Several dietary polyphenols have the capacity to manage inflammation and thus supplementation may be an effective component of a long-term training plan. PURPOSE:The purpose of this study was to investigate the effect of combined oral supplementation with curcumin and boswellia serrata prior to and following three consecutive days of intense interval exercise. METHODS:All protocols were approved by the University IRB committee and participants …

Inflammation-Associated Rna Signaling Is Reduced Following A Half-Marathon Race When Supplemented With Curcumin And A Pomegranate Extract, Elizabeth A. Tanner, Melody A. Gary, Asheal A. Davis, Brian K. Mcfarlin
International Journal of Exercise Science: Conference Proceedings
Prolonged endurance exercise performances provide a unique model for investigating the combined effects of oxidative stress and eccentric muscle contraction on differential gene expression with nutritional interventions known to blunt inflammation. Dietary polyphenols (i.e. curcumin, pomegranate, etc.) have been shown to reduce exercise-induced inflammation associated mRNA and protein expression with fewer side effects than NSAIDs. PURPOSE: To investigate the effect of combined curcumin (500-1000 mg/d; Longvida®) and pomegranate extract (500-1000 mg/d; Pomella®) supplement for 30-days on mRNA expression following a half marathon race. METHODS: All protocols were approved by the University IRB committee and participants gave written informed consent. Participants …

Individuals participating in prolonged exercise sessions and associated training experience regular inflammation and muscle soreness. Natural products with known anti-inflammatory and/or oxidative stress blocking effects represent attractive options to traditional NSAID treatments. PURPOSE: To investigate the effect of combined curcumin (500-1000 mg/d; Longvida®), pomegranate extract (500-1000 mg/d; Pomella®), and Methylsulfonylmethane (500-1000 mg/d; OptiMSM®) supplement for 30-days on protein inflammatory biomarkers, inflammation-associated RNA, and oxidative. METHODS: All protocols were approved by the University IRB committee and participants gave written informed consent. Subjects were supplemented for 30-d prior to the half marathon race. Venous blood samples were collected for serum or RNA …
