“…Quadriceps strength was measured during isometric, concentric, and eccentric contraction at slow (60°/s) and fast (180°/s) velocities. These velocities of contraction during isokinetic testing are associated with functional performance (e.g., hopping, jumping) [ 31 , 32 ]. Quadriceps strength was measured before and after FKJC (immediately, 20, and 40 min after) to examine the change in quadriceps strength over time.…”

Recent evidence suggests an innovative approach to muscle conditioning: focal knee joint cooling (FKJC) appears to improve quadriceps function, including static (isometric) strength. However, there is limited evidence on the effects of FKJC on dynamic (concentric and eccentric) strength. Thus, the purpose of the study was to examine dynamic quadriceps strength following FKJC as well as static strength. Twenty-one college-aged participants volunteered. They randomly underwent 20 min of FKJC and control condition at least 72 h apart. FKJC involves two ice bags, placed on the anterior and posterior surfaces of the knee, whereas the control condition received a plastic ice bag filled with candy corn. We assessed isometric and isokinetic (concentric and eccentric) quadriceps strength at two different velocities (60°/s and 180°/s). Participants performed three maximal voluntary contractions for each mode of muscle contraction, before and after each treatment (immediately, 20, and 40 min after). The outcome variable was maximum knee extension peak torque. FKJC did not change peak torque during any mode of muscle contraction (p > 0.05). The current findings suggest that 20 min of FKJC does not change static (isometric) or dynamic (isokinetic) strength of the quadriceps. FKJC was neither beneficial nor harmful to static or dynamic muscular strength.

“…Several studies have examined the relationship between the ability ff walking sprint and muscle strength (Moirenfeld et al, 2000). From the research results, the relationship between muscle strength and vertical jump performance (CMJ and SJ) was found by different authors (Atabek et al, 2009;Paasuke M, Ereline J, 2001;Tsiokanos et al, 2002). Furthermore, (Tharp et al, 1985) found a significantly strong correlation between isokinetic knee strength and the strength and anaerobic capacity of female runners and female middle-distance runners.…”

Measurement of Body Composition (BC) is carried out for various purposes, such as uniting the growth and development of athletes and determining motor performance, physical activity, changes in body composition, as well as nutritional interventions. This study aimed to determine the relationship between Body Composition (BC) and anaerobic ability of female futsal players aged 17-19 years. Twenty female futsal players participated in this study. Muscle mass, Body Mass Index (BMI), Body Fat Percentage, Water Percentage, Protein Percentage, Basal Metabolism, Visceral Fat, and Bone Mass were measured to determine the fat percentage of bone, air, and muscle in the body. Measurement of body composition was also intended to detect the food intake needed by the body and obtain information relevant to disease prevention and treatment. The Running Based Anaerobic Sprint Test (RAST) was conducted to measure the anaerobic endurance. The research method used was a descriptive correlation with a quantitative approach. The finding showed no correlation between Running Based Anaerobic Sprint and Body Fat Percentage, Water Percentage, Protein Percentage, Basal Metabolism, and Visceral Fat. However, there was a positive relationship between Muscle Mass, Body Mass Index (BMI), Bone Mass of the samples, and their Running Based Anaerobic Sprint (p0.05). It concludes that the score of Muscle mass, Body Mass Index (BMI), and Bone Mass affected the anaerobic capacity of female futsal players aged 17-19 years. The normal status of body composition and body fat percentage can be maintained through maintaining consumption patterns and increasing physical activity.

“…There are even authors whose results show the absence of correlation between PT and CMJ. For example, (Atabek & Sönmez, 2009;Blackburn & Morrissey, 1998;Kovačević, Abazović, Bradić, & Vrcić, 2012), reported statistically insignificant correlation coefficients between these variables.…”

The purpose of this study was to evaluate the relationship between knee extensor and flexor muscles strength and vertical jump in professional female volleyball players. Forty-one female volleyball players participated in this study. Isokinetic PT and was measured at 60°/s, whilst CMJ performance using a force plate. The participants were later divided to WG (weaker group - PT/BW<2) and SG (stronger group - PT/BW>2). Isokinetic concentric knee extension and flexion PT was significantly correlated with CMJ performance. However, higher correlation coefficients were obtained at the non-dominant leg. No significant differences were found but mere trend favoring non-dominant leg muscles in the weaker group. Strong positive correlation exists between isokinetic knee PT and CMJ height in professional female volleyball players. When divided and compared to WG and SG the results indicate weaker players tend to modify their technique individually and towards unilaterality as so they could maximize their performance.
