Journal for Sports Neuroscience
Purpose: The purpose of this study was to utilize the Ratings of Perceived Exertion (RPE) Clamp Model to examine the effects of joint angle on the composite, inter-, and intra-individual patterns of responses for torque and neuromuscular parameters during fatiguing isometric tasks anchored to RPE of 8 (RPE = 8) at elbow joint angles of 75° (JA75) and 125° (JA125) for men. Methods: Ten men (Mean ± SD: age: 20.7 ± 1.2 yrs; height: 181.6 ± 6.0 cm; body mass: 83.7 ± 14.9 kg) performed 2,3 s forearm flexion maximal voluntary isometric contractions (MVIC) with the dominant arm before and …

Journal for Sports Neuroscience
Purpose: The purpose of this study was to examine the effects of joint angle on MVIC and neuromuscular responses at task failure following sustained, isometric forearm flexion tasks anchored to a rating of perceived exertion (RPE) of 8 (RPE = 8) and anchored to the initial torque that corresponded to RPE = 8 (TRQ). Methods: Ten women (age: 21.0 ± 2.8 yrs; height: 168.5 ± 7.2 cm; body mass: 68.0 ± 7.2 kg) performed 2, 3 s MVICs at joint angles (JA) of 75°, 100°, and 125° (randomized order) before and after sustained, isometric forearm flexion tasks to failure at …

Journal for Sports Neuroscience
Purpose. This study examined the sex-related differences in muscular performance and neuromuscular (electromyographic [EMG] and mechanomyographic [MMG] amplitude [AMP] and mean power frequency [MPF]) responses during fatiguing leg extension repetitions performed at the critical load (CL). Methods. Eleven men and nine women completed one-repetition maximum (1RM) testing, repetitions to failure at 50, 60, 70, and 80% 1RM to determine CL, and repetitions to failure at CL, on separate days. The EMG and MMG, AMP and MPF signals and number of repetitions completed were recorded. Results. There were no sex-dependent responses in the %1RM that corresponded to, the number of repetitions …

Biomechanical Properties Of Land Based And Shallow Water Wait: A Comparative Review Of Literature, Mostafa Yaghoubi, Philip Fink, Wyatt H. Page, Sarah P. Shultz
International Journal of Aquatic Research and Education
Aquatic locomotion exercises are frequently used in rehabilitation and cross-training for land-based athletes. Hydrostatic pressure, thermal conductivity and drag force affect a person's ability to move; therefore, it is important to understand differences of biomechanical gait in water vs land. This review investigated biomechanical differences between shallow water and land-based exercises. PubMed, Google Scholar, SPORTDiscus and Scopus were searched; 33 studies included walking forward (27), backward (6) and running (6). Electromyographic amplitude was similar or less in submaximal intensity during aquatic gait, in comparison to on land. At maximal intensities, however, the amplitude was similar (n=5) or higher (n=4) in …
