Effects of hormonal growth promotant (HGP) implantation on liveweight, carcass and meat quality measurements were examined using 80 Angus yearling cattle. After entry to the feedlot, 40 steers and 40 heifers were implanted with Revalor-S (28 mg oestradiol and 140 mg trenbolone acetate) and Revalor-H (20 mg oestradiol, 200 mg trenbolone acetate), respectively. Cattle were slaughtered after 55 and 65 days on feed. Samples from the Mm. longissimus dorsi, biceps femoris (the cap and body portions), gluteus medius (the eye and D portions), infraspinatus and triceps brachii were prepared for sensory testing after aging for 5 and 21 days after slaughter. A total of 854 muscle samples were cooked by grill (601) or roast (253) methods and served to consumers using the Meat Standards Australia taste panel protocols. When adjusted to the same initial liveweight, implantation with Revalor-H and Revalor-S resulted in a 4 and 7% increase in slaughter weight, respectively. Implantation resulted in an increased ossification score in steers (P < 0.05), but not in heifers. There was a significant interaction (P < 0.05) between HGP implantation and days aged for shear force. There was a small effect of HGP implants on compression (P < 0.05), but not on cook loss and intramuscular fat percentage. Muscles differed in their response to HGP implantation (P < 0.05) for tenderness, overall liking and palatability scores. Muscles also differed in their aging rates after slaughter (P < 0.05). The greatest response in sensory scores to HGP implantation was found in those muscles that had the highest aging rates. Possible mechanisms by which muscles differed in their response to HGP implantation are discussed.

Abstract Consumption of β-hydroxy β-methylbutyrate (HMB) alters muscle composition and metabolism leading to strength and agility improvements in human athletes. To determine if HMB affects athletic performance and muscle function in horses, Thoroughbred geldings were fed a control (CON; n = 5) or HMB (n = 6) supplement for 6 wk prior to completing a standardized exercise test (SET). Gluteus medius (GM) muscle biopsies were obtained before the SET for fiber typing. Heart rate, biceps femoris (BF) and semitendinosus (ST) surface electromyograms (EMG), and fore and hind limbs metacarpophalangeal joint angles were captured at the gallop of the SET. Results demonstrate that HMB supplementation increased (P &lt; 0.05) the percentage of type IIA and IIA/X muscle fibers in the GM with a corresponding decrease (P &lt; 0.05) in type IIX fibers. The percentage of type I fibers was unaffected by diet. Supplementation with HMB did not result in any measurable effects on performance or biomechanical properties by comparison to CON. Supplementation with HMB resulted in an increase (P &lt; 0.05) in ST median frequency at speeds of 10 m/s and greater. Increasing treadmill speed resulted in an increase (P &lt; 0.05) in stride length and the maximal proximal forelimb fetlock angle, and a decrease (P &lt; 0.05) in stance phase time of the gait cycle. Integrated EMG (iEMG) increased (P &lt; 0.05) with increasing treadmill speeds for both the BF and ST with the BF exhibiting greater (P &lt; 0.05) iEMG values than the ST. In summary, HMB increased the percentage of type IIA GM fibers, which did not translate into improved performance.

AbstractThe purpose of the study was to compare kinematics and muscle activity between two variations of unilateral squats under different stability conditions. Twelve male volunteers (age: 23±5 years, mass: 80±17 kg, height: 1.81±0.11 m, strength-training experience: 4.3±1.9 years) performed four repetitions with the same external load (≈4RM). Two variations (with the non-stance leg forwards vs. backwards) were performed in a Smith-machine and free-weight condition. The variables were barbell velocity, lifting time and surface electromyography activity of the lower extremity and trunk muscles during the descending and ascending phase. The main findings were 1) peak force was higher when performing the unilateral squats in the Smith machine; 2) peak ascending barbell velocity increased from repetition 3–4 with free weight; and 3) muscle activity from the rectus femoris, vastus lateral, biceps femoris, gluteus medius, and erector spinae increased with repetitions, whereas gluteus, and medial vastus and shank muscles were affected by the conditions. It was concluded that more peak force could be produced because of increased stability. However, peak barbell velocity increased from repetition to repetition in free-weight unilateral squats, which was probably because the participants grew more comfortable. Furthermore, increased instability causes more gluteus and vastus medial activation and foot variations mainly affected the calf muscles.

Crossbred Pigs

Three groups, each consisting of six crossbred pigs weighing approximately 100 kg, were used to determine the effects of three preslaughter stunning methods on certain quality characteristics of the longissimus, semitendinosus and biceps femoris muscles. The three methods of stunning were captive-bolt, electric shock and oral dantrium (dantrolene sodium, a muscle relaxant) followed by captive-bolt. The three muscles were significantly different to each other in some of the quality traits, but the responses to treatments were similar in the three muscles. Without dantrium, captive-bolt stunning resulted in reduced muscle pH at 45 min postmortem and a greater water exudation in muscles at either 1 h or 24 h postmortem compared to electrically stunned pigs. Dantrium treatment followed by captive-bolt stunning eliminated these differences. Key words: Pigs, PSE, stunning, muscle relaxant, dantrolene

Fitness Sport

Running on a road for fitness, sport, or recreation poses unique challenges to the runner, one of which is the camber of the surface. Few studies have examined the effects of camber on running, namely, kinematic studies of the knee and ankle. There is currently no information available regarding muscle response to running on a cambered road surface. The purpose of this study was to investigate the effects of a cambered road on lower extremity muscle activity, as measured by electromyography in recreational runners. In addition, this study examined a true outdoor road surface, as opposed to a treadmill surface. The mean muscle activity of the tibialis anterior, lateral gastrocnemius, vastus medialis oblique, biceps femoris, and gluteus medius were studied. Fifteen runners completed multiple running trials on cambered and level surfaces. During the stance phase, mean activities of tibialis anterior, lateral gastrocnemius, and vastus medialis oblique were greater on the gutter side than the crown side. There were no differences in mean muscle activity during the swing phase. The findings of this study suggest that running on a road camber alters the activity of select lower extremity muscles possibly in response to lower extremity compensations to the cambered condition.

Мета: визначити особливості функціональних порушень кульшових суглобів, що сформувались внаслідок дисплазії у дітей дошкільного віку. Матеріал і методи: у дослідженні, яке проводилося протягом 2014–2019 рр., взяла участь 131 дитина дошкільного віку (середній вік 5,6±0,5 років). Учасників було поділено на дві групи: основну (ОГ, n=68) – діти з односторонньою ДКС за анамнезом (виявлено за результатами аналізу медичних карт) та групу порівняння (ГП, n=63) – діти без порушень з боку кульшових суглобів. Для оцінки результатів використано метод тензодинамометрії (мануальний м’язовий тестер на базі датчика механічного зусилля “EXPANDER”) та метод гоніометрії. Результати:результати дослідження показників електротензодинамометрії м’язів нижніх кінцівок у дітей ОГ свідчать про достовірне зниження сили м’язів-абдукторів стегна (m. gluteus medius, m. gluteus minimus, m. tensor fasciae latae) ушкодженої кінцівки відносно інтактної у кульшовому суглобі (інтактна – 85,8±6,8 та уражена 54,5±4,9 ( ±S), (p ≤0,05)) та гіпертонус м’язів-аддукторів стегна (m. gracilis, m. adductor longus, m. adductor brevis) з боку ураженої кінцівки відносно інтактної кінцівки (інтактна – 68,2±4,4, уражена – 95,8±4,1, ( ±S), (p ≤0,05). Під час вивчення показників тензодинамометрії у дітей з ДКС виявлено сильний прямий кореляційний взаємозв’язок між станом м’язового апарату і розвитком привідної контрактури кульшового суглоба (коефіцієнт кореляції між показниками сили м’язів-абдукторів стегна та амплітудою відведення – r = 0,7 (сильний зв’язок, p < 0,05). Висновки: тензодинамометричне дослідження м’язів дало можливість виявити зниження тонусу м’язів-абдукторів стегна, biceps femoris, m. semitendinosus, m. semimembranosus, m. quadriceps femoris, m. sartorius. Результатом дисбалансу функціональної активності м’язів є формування торсійно-вальгусної деформації кульшового суглоба, яка вимагає поетапного індивідуального проведення реабілітаційно-корекційних втручань. Ключові слова дисплазія кульшових суглобів, дошкільний вік.
