Kinematic Analysis Of Four Plyometric Push-Up Variations, Laura H. Moore, Michael J. Tankovich Atc, Cscs, Bryan L. Riemann Phd, Atc, George J. Davies Dpt, Atc
International Journal of Exercise Science
International Journal of Exercise Science 5(4) : 334-343, 2012. Plyometric research in the upper extremity is limited, with the effects of open-chain plyometric exercises being studied most. Kinematic and ground reaction force data concerning closed-chain upper extremity plyometrics has yet to be examined. Twenty-one recreationally active male subjects performed four variations of plyometric push-ups in a counterbalanced order. These included box drop push-ups from 3.8 cm, 7.6 cm, 11.4 cm heights, and clap push-ups. Kinematics of the trunk, dominant extremity and both hands were collected to examine peak flight, elbow flexion at ground contact, elbow displacement, and hand separation. Additionally …

Few studies have compared anthropometric characteristics among national class athletes from different resistance training disciplines, such as Olympic Weightlifting (OL), Power Lifting (PL), and Bodybuilding (BB). Objective: The purpose of the current study was to determine if significant differences exist in the relationship between thigh muscle cross-sectional area and back squat strength among national class athletes from the sports of OL, PL, and BB. Methods: Fifteen national class athletes were assessed for back squat strength, mid-thigh circumference, and mid-thigh skinfold from which total thigh cross-sectional was estimated. A series of One-Way ANOVAs and Pearson Product Moment Correlations were used to …

Chronic Changes In Serum Il-6 And Tnf-Α Following 12 Weeks Of Concurrent Resistance And Aerobic Exercise Are Dependent On Exercise Mode And May Affect Adaptation, Brad S. Lambert, Justin P. Dobson, Stephen F. Crouse
Chronic Changes In Serum Il-6 And Tnf-Α Following 12 Weeks Of Concurrent Resistance And Aerobic Exercise Are Dependent On Exercise Mode And May Affect Adaptation, Brad S. Lambert, Justin P. Dobson, Stephen F. Crouse
International Journal of Exercise Science: Conference Proceedings
PURPOSE: To examine physiological responses to concurrent resistance and land treadmill training (RT-LTM) compared to concurrent resistance and aquatic treadmill training (RT-ATM) and the chronic effect of each on serum TNF-α and IL-6 (cytokines associated with chronic inflammation, CVD, and skeletal muscle metabolism). METHODS: Twenty-six untrained subjects (M: n=13, 98.6±17.1kg, 182.2±6.2cm, 34±11yrs, F: n=13, 78.9±14.0kg, 165.1±5.1cm, 38±11yrs) were screened to assess VO2max, body composition (DEXA), and strength (Lifts: leg press, chest press, leg curl, lat pull, leg ext, triceps push-down, biceps curl). Subjects were then randomized into 2 groups: RT-LTM (M=6, F=7), RT-ATM (M=7, F=6). Each performed progressive …
Increase In Muscle Power Induced By Periodized Resistance Training In Elderly Women, Cláudio De Oliveira Assumpção, João Bartholomeu Neto, Christiano Bertoldo Urtado, Maria Imaculada L. Montebelo
Increase In Muscle Power Induced By Periodized Resistance Training In Elderly Women, Cláudio De Oliveira Assumpção, João Bartholomeu Neto, Christiano Bertoldo Urtado, Maria Imaculada L. Montebelo
International Journal of Exercise Science: Conference Proceedings
Resistance training (RT) has been recommended to prevent muscle force and power decrease induced by aging. Neuromuscular tests are important tools to analyze muscle force function. The objective of the present study was to analyze the behavior of lower limb muscle power of elderly women submitted to 12 weeks of periodized RT. 16 women aged 65.5±3.6 years with a minimum of one year of previous experience in strength training were selected, they performed 24 sessions of RT divided in 3 mesocycles (MA, MB and MC), of 8 sessions each, with a session frequency of twice a week. The MA with …
Strength Training And Nandrolone Decanoate Decreased Myostatin Expression, Uliana Sbeguen Stotzer, Rita De Cássia Marqueti, Milena De Moura Paschoal, Heloisa Sobreiro Selistre De Araújo
Strength Training And Nandrolone Decanoate Decreased Myostatin Expression, Uliana Sbeguen Stotzer, Rita De Cássia Marqueti, Milena De Moura Paschoal, Heloisa Sobreiro Selistre De Araújo
International Journal of Exercise Science: Conference Proceedings
Nandrolone decanoate is a androgenic anabolic steroid (AAS) which targets the satellite cells in skeletal muscles. These cells are considered the stem cells of skeletal muscle, and they are essential for muscle growth and repair. Myostatin is a negative regulator of muscle mass that inhibits myoblast proliferation and differentiation. Recognizing the mechanisms related to AAS action in skeletal muscle is critical for a better understand of muscular physiology under AAS use. The aim of this study was to investigate the effects of aquatic plyometric training (APT) with overload associated with AAS on the gastrocnemius muscle of rats. Animals were grouped …
Aquatic Plyometric Training Associated With Androgenic Anabolic Steroids Do Not Increase Muscle Mass In Rats, Uliana Sbeguen Stotzer, Rita De Cássia Marqueti, Milena De Moura Paschoal, Heloisa Sobreiro Selistre De Araújo
Aquatic Plyometric Training Associated With Androgenic Anabolic Steroids Do Not Increase Muscle Mass In Rats, Uliana Sbeguen Stotzer, Rita De Cássia Marqueti, Milena De Moura Paschoal, Heloisa Sobreiro Selistre De Araújo
International Journal of Exercise Science: Conference Proceedings
To improve athletic performance or for aesthetic reasons, athletes and no athletes may use androgenic anabolic steroids (AAS). Numerous studies have reported that aquatic plyometric training (APT) can improve muscular strength and vertical jump; however the effect of these training protocols on muscular mass are poorly investigated. The aim of this study was to investigate the effects of APT associated with AAS in the soleus, gastrocnemius (Gastro), extensor digitorium longus (EDL) and tibialis anterior (TA) skeletal muscles in rats. Animals were grouped into: sedentary (S); S with AAS (AAS); trained (T); and T with AAS (AAST). Exercised groups performed jumps …

Effects Of Carbohydrate-Protein Ingestion Post-Resistance Training In Male Rugby Players, Colin J. Coyle Msc, Bernard Donne, Nick J. Mahony
International Journal of Exercise Science
Evidence suggests that carbohydrate-protein (CHO-PRO) drinks post-exercise are an advantageous nutritional recovery intervention. Resistance trained (n = 14, mean ± SD; age 19 ± 1 yr, mass 95 ± 9 kg, % fat 17 ± 4 % and BMI 28.5 ± 1.8 kg.m-2) male rugby players participated in a study investigating effects of carbohydrate (CHO) and CHO-PRO drinks on subsequent resistance exercise performance. Following an initial resistance training (RT) protocol consisting of 8 circuits of 5 discrete exercises at 10 repetition maximum (RM), participants received 10 mL.kg-1 BM of randomised sports drink (LCHO, HCHO and CHO-PRO) on …

Individuals who are currently sedentary, unfit, or overweight can benefit metabolically from simply taking breaks from sitting. Since avoidance of sedentary behavior appears to have a large impact on glycemic management, all individuals with type 2 diabetes should be encouraged to minimally engage in greater daily movement to better manage their diabetes and body weight. In addition, engaging in physical activity of any intensity (including low-intensity ones) likely positively impacts insulin action and blood glucose control acutely. Moreover, as long as total caloric expenditure during exercise is matched (i.e., total exercise dose), daily exercise may be done every other day …
