The purpose of this study was to use a holistic approach to investigate changes in jumping performance, kinaesthesia, static balance, isometric strength and fast stepping on spot during a 5-day recovery period, following an acute bout of damaging exercise consisted of drop jumps and leg curls, where specific emphasis was given on the hamstring muscles. Eleven young healthy subjects completed a ...

Introduction The hamstring muscles are frequently implicated in posterior thigh pain due to strains. The hamstring muscles are the three most superficial muscles that span the posterior thigh, and consist of the biceps femoris, semitendinosus, and semimembranosus. The long head of biceps femoris originates from the inferiomedial aspect of the ischial tuberosity and inserts into the head of the ...

This study examined the effectiveness of a functional hamstring training exercise, the razor curl on conditioning the hamstring and gluteal musculature. Eight healthy, female intercollegiate athletes participated (mean age 20.8 +/- 3.9 years; mean height, 177.8 +/- 10.9 cm; mean weight, 67.3 +/- 9.9 kg). Electromyographic (EMG) data were collected on the following muscles: medial hamstring (sem...

QUESTION Does eccentric muscle training of hamstring muscles reduce the rate of hamstring injuries in male soccer players? DESIGN Cluster randomised, controlled trial with concealed allocation. SETTING The 5 top men's soccer divisions in Denmark. PARTICIPANTS First team squad soccer players from teams in the top 5 national soccer divisions were included. Players who joined a team after th...

Abstract Objectives This study aimed to examine the effect of knee pain perception on muscle strength and endurance among elite female handball players. Methods included 60 players who participated in training competition from January December 2019. Muscle strength, endurance, hamstring/quadriceps ratio were estimated using Computer Sports Medicine, INC (Cybex, HUMAC, USA). The independent samp...

The patient was a 25-year-old (height: 183 cm, weight: 86 kg) professional rugby league winger. He had suffered a recurrent episode of a left hamstring (biceps femoris) injury at a training drill late in the season (Day 0). This occurred suddenly while changing direction at pace. The player felt the degree of pain when injured to be very similar to his previous episode earlier in the season, wh...

The purpose of this study was to examine intratester reliability of a test designed to measure tightness in the hamstring muscles. The test measures the angle of knee flexion with a pendulum goniometer after active knee extension with the hip stabilized at 90 degrees flexion. The angle of knee flexion represents hamstring tightness. After an instruction session for the subjects, the hamstring m...

In this study, we examined hamstring muscle activation at different running speeds to help better understand the functional characteristics of each hamstring muscle. Eight healthy male track and field athletes (20.1 +/- 1.1 years) performed treadmill running at 50%, 75%, 85%, and 95% of their maximum velocity. Lower extremity kinematics of the hip and knee joint were calculated. The surface ele...
