The skipping is the movement modeled after sprint running. The purpose of this study was to examine effects of skipping training on physical fitness, sprint ability and sprinting form. Nine non-athlete male university students participated in the training consisted of skipping exercises three days per week for eight weeks. The experiment was performed before and after the training period. The experiment was composed of measuring physical fitness and filming 100 m dash. Variables of analysis were: 1) back strength, vertical jump, stepping effeciency while sitting on a chair, 2) maximum anaerobic power, 3) isokinetic peak torque and isokinetic endurance of knee extension and flexion, and hip flexion, 4) 100m sprint record, and sprint record in each 20m sections, 5) running velocity, step frequency and step length, 6) thigh angle and angular velocity, and knee angle and angular velocity, 7) time for one step, support time and nonsupport time, 8) locus of ankle around trochanter major. Results were as follows: 1. Factors of physical fitness such as back strength, maximum anaerobic power and isokinetic peak torque were significantly improved after training. 2. 100m sprint record was significantly shortened, due to the increase of step frequency. 3. After training, the maximum running velocity was kept up for a longer period, and running velocity in 80 m to 100 m became remarkably faster. 4. After training, time for one step and nonsupport time were significantly shortened. 5. The knee lift during recovery phase became significantly higher. 6. The angular velocity of thigh of recovery leg became significantly faster. It is concluded that the skipping training for eight weeks improves sprint ability, sprinting form and physical fitness related to sprint running.

拇指および指示指で小物体を摘み上げる運動において, 視覚から得られる物体の大きさ情報が摘み力および持ち上げ力の発揮プログラムにおよぼす影響について検討した.(1) 視覚から得られる物体の大きさに応じて, 持ち上げ時に発揮されるGrip ForceおよびLoad Forceはスケールされた.このことは力発揮プログラムの予測的制御変数として物体の大きさ情報が利用されていると推察された.(2) 大きさ情報が遮断されると, いずれの大きさの箱に対しても発揮される力は大きな箱を持ち上げる際に発揮される力の方へ変化した.このことは大きさ情報が, 最も大きな箱に対して発揮される力を基準として, それより小さな箱に対してより小さな力を発揮するように作用した結果と推察された.本研究の一部は, 帝塚山学術研究助成金および文部省科学研究費 (基礎研究 (C) 11680067) により行われた.

Effects of sprint training were examined on the form in sprint running. Six non-athlete male university students aged 19-20 years engaged in the training program consisted of 50 m and 100 m sprint running three times a day, three days per week, for a period of ten weeks. They ran 50m and l00m using a starting block with maximum effort before and after the training period, and their form in sprint running was filmed at 100 frames per second at 40 m (50 m dash) and 85 m (100 m dash)point from the start 1ine. Further, an accomplished male sprinter (21 years of age) ran 50 m dash and his sprint form was filmed at 40 m point. Length of one cycle (length of two steps), duration of one cycle (time needed for two steps), velocity at the point, sprint record and seven kinematic factors were measured. Kinematic factors were 1) Upper leg angle and angular velocity, 2) Lower leg angle and angular velocity, 3) Knee angle and angular velocity, 4) Locus of toe around trochanter major. Results were as follows. 1) Before training, the toe movement around trochanter major in the former half of swing phase of non-athlete was lower than that of the sprinter (50m dash). 2) After training, the toe movement around trochanter major in the former half of swing phase was higher than that measured before the training (50m dash). 3) After training, maximum angular velocity of upper leg during top speed in 50 m and 100m sprint running significantly became faster than those measured before training. Maximum and minimum angular velocity of the knee during top speed in 50m sprint running significantly became faster than those measured before training. 4) Duration of one cycle at 40 m (50 m dash) and 85 m (100 m dash) point during sprint running shortened after the training significantly. Length of one cycle at the same point in some subjects lengthened, while such was not the case in other subjects. Running velocity which was culculated from duration and length of one cycle improved significantly. It is concluded that the short period of sprint training has the effect to improve sprint form and the sprint ability of male adults.
