Tidigare forskning visar på ett positivt samband mellan styrketräning och löpekonomi. I föreliggande studie undersöktes effekten av djupa explosiva knäböjningar på löpekonomin hos långdistanslöpare. I studien deltog elva deltagare varav sex i interventionsgruppen och fem i kontrollgruppen. Styrketräningen skulle vara tidseffektivt, max 20 min och då enbart en övning. Basövningen knäböjning med stången bakom nacken valdes. Huvuddelen av all knäböjsträning under en åtta veckors period, utfördes med en belastning på 60% av 1RM 2-6 rep i 2-6 set och då med fokus hög hastighet i både den excentriska och koncentriska fasen samt ca 1 min vila mellan seten. Efter avslutad träningsperiod sågs signifikant förbättring vad gäller maxstyrka, 1RM och maximal Power. Samtliga deltagare i interventionsgruppen fick en positiv styrkeökning med ett snitt på 14,5%. Studien visar även en tendens till förbättrad löpekonomi hos interventionsgruppen. / Previous research shows a positive link between strength training and running economics. In the present study, the effect of deep power squats on the running economics of long distance runners was investigated. The study included eleven participants, six were in the intervention group and five in the control group. The strength training would be time efficient, max 20 min and then only one exercise. We chose the basic exercise squats with the barbell behind the neck. The majority of all squats exercises during a period eight week with a load of 60% of 1RM 2-6 reps in 2-6 sets and then focused high speed in both the eccentric and concentric phase and about 1 min rest between the sets. At the end of the training period, we could see a significant improvement in maximal 1RM and maximum Power. All participants in the intervention group received a positive increase in strength, with an average of 14.5%. The study also shows a tendency for improved running economics in the intervention group.

The Swedish Wrestling Association are in the process of constructing a new Elite Development Plan which will include the fields: Elite Sports Environment, Coaching Development, Performance Development, Performance Analysis and Research Development. This study will aim to produce knowledge in the field Performance Development. The study analyzes elite wrestlers from the Swedish National Wrestling Team views on how to develop their performance and what factors are most significant. To answer the purpose of the study the Swedish Wrestling Association helped us conduct interviews with eight different wrestlers whom all had different backgrounds. The result showed that there are several important factors that have a significant impact on their performance development, which include training facilities, setting clear short and long-term goals and having support from their surroundings. A short conclusion of the study is that the Swedish wrestlers all have the physical ability to compete on a high international level, however, that they lack in the mental ability which disables them to take the next step in their development. Our hope with this study is that it will lay a foundation for the Swedish Wrestling Association and their future Elite Development Plan.
