preperformance warm-up routines are commonly promoted and are specifically designed to prepare an individual for high-intensity physical activity and reduce the risk of injury (9, 56).The routines typically include cardiovascular work, stretching, and strong muscular contractions (with progressing intensity), which promote increased peripheral blood flow to the working muscle, elevated Cited by: Resistance training (RT) enhances muscle protein synthesis and hypertrophy while increasing strength and power.

The control group directly underwent isokinetic muscle testing without warm-up, while the warm-up group started power walking at a strength of 40–60% of the predicted maximum heart rate, performed light running for 10 minutes, and then underwent isokinetic muscle testing.
The warm-up with stretching group performed light running for 5 minutes Cited by: 4. Further examination of isokinetic testing protocols revealed that the warm-up velocities used in the literature range from 30 to °.s -1, 2,  and in many cases.
Therefore, isokinetic testing offers significant clinical controls, such as: isolate particular muscle groups, determined contraction types and range of motion, and accommodated resistance.

Therefore, including static stretches in a warm-up routine prior to muscular strength testing may be permissible, as long as the total stretch duration is not excessive (four sets of exercises for each muscle group with seconds stretch duration is recommended) and that the exercises are performed consistently during subsequent testing.
Muscle strength imbalances around the knee are often observed in athletes after anterior cruciate ligament (ACL) surgery and hamstring muscle injury. This study examined three hamstrings-to-quadriceps (H:Q) strength ratio types (conventional, functional, and mixed) in thirteen female athletes with a history of hamstring injury, fourteen basketball players following ACL reconstruction and 34 Author: Eleftherios Kellis, Nikiforos Galanis, Nikolaos Kofotolis.

Isokinetic muscle training: background - Exercise is a planned, structured and repetitive physical activity. Exercise not only conditions the body, but it also improves health, maintains fitness and helps rehabilitate injured parts of the body. Exercise includes cardiovascular activities like running or walking as well as weight training.

Comparison between warm-up and cool-down stretching programs on hamstring extensibility gains in primary schoolchildren. Proper training and balanced strengthening are key factors in prevention of musculotendinous injuries as well.
Warm-up and stretching are essential to preventing muscle injuries by increasing the elasticity of muscles and smoothing muscular contractions. Improper or excessive stretching and warming up can, however, predispose to muscle by: Although, isometric testing is shown to be a reliable and valid method [22,23], isokinetic testing is more representative of muscle action during dynamic tasks of daily life.
Despite no actions in real life occur at constant velocity, isokinetic testing provides a more natural movement condition due its dynamic nature, whereby a maximal torque.

Introduction Compared to other physiological parameters our understanding of the age and sex associated changes in strength are relatively limited, but development of equipment, and increased understanding of growth and maturation issues, have provided new insights into paediatric strength development.
