Effects of Explosive Type Strength Training on Selected Physical and Technical Performance Characteristics in Middle Distance Running - a Case Report

Abstract

Introduction. Distance running performance is a simple function of developing high speeds and maintaining this speed as long as possible. Thus a correct running technique becomes an important component of performance. Technique is effective if the competitor can reach a better performance result with the same or lower energy consumption. The purpose of this investigation was to examine a six weeks application explosive type strength training on lower extremities power and maximum speed performance improvement in order to facilitate running technique in sub-elite male middle-distance runner. Material and methods. A sub-elite runner performed twice a week special exercises and running drills. He completed a pre and post-training jumping (SJ, CMJ, standing long jump, standing five jump) and speed (20 m from standing and flying start) field tests. For kinematical analysis, a video (SIMI Motion System) of a 10 m sprint from a 20 m flying start was collected. Results. Improvement occurred in all measurements but strong changes were evident in the 10 m from 20 flying start and in stride frequency from 3.90 to 4.01 Hz, due to decreasing of ground contact time from 160 to 156 ms. No strong evidence in the participant's running technique changes. Conclusion. This proved that six weeks of dynamic type strength program seems to improve neuromuscular characteristics of running speed and explosive power and no changes in running technique.

Relationships Between Sprint, Jumping and Strength Abilities, and 800 M Performance in Male Athletes of National and International Levels

to explain the 800 m performance ( Craig and Morgan, 1998 ; Duffield et al., 2005 ; Hill, 1999 ; Lacour et al., 1990 ; Spencer and Gastin, 2001 ). Actually, very few studies have examined the importance of different neuromuscular variables on middle-distance running performance ( Hudgins et al., 2013 ). In addition, it has been suggested that strength training could lead to enhanced long-term endurance capacity both in well-trained individuals and elite endurance athletes ( Aagaard and Andersen, 2010 ). Thus, the purpose of this investigation was to examine the

Post‐Activation Potentiation Increases Recruitment of Fast Twitch Fibers: A Potential Practical Application in Runners

Abstract

To determine the relationship between fatigue and post-activation potentiation, we examined the effects of sub-maximal continuous running on neuromuscular function tests, as well as on the squat jump and counter movement jump in endurance athletes. The height of the squat jump and counter movement jump and the estimate of the fast twitch fiber recruiting capabilities were assessed in seven male middle distance runners before and after 40 min of continuous running at an intensity corresponding to the individual lactate threshold. The same test was then repeated after three weeks of specific aerobic training. Since the three variables were strongly correlated, only the estimate of the fast twitch fiber was considered for the results. The subjects showed a significant improvement in the fast twitch fiber recruitment percentage after the 40 min run. Our data show that submaximal physical exercise determined a change in fast twitch muscle fiber recruitment patterns observed when subjects performed vertical jumps; however, this recruitment capacity was proportional to the subjects’ individual fast twitch muscle fiber profiles measured before the 40 min run. The results of the jump tests did not change significantly after the three-week training period. These results suggest that pre-fatigue methods, through sub-maximal exercises, could be used to take advantage of explosive capacity in middle-distance runners.

The Relationship Between Tactical Positioning and the Race Outcome in 800-M Running at the 2016 Olympic Games and 2017 IAAF World Championship

semi-finals, possibly demonstrating a will to win each race. Based on this finding, it can be suggested that superior athletes tend to achieve higher finishing positions in both preliminary qualifying rounds and finals showing a will to win each race instead of qualifying as faster losers. In this study, we define a ‘high position’ as being one of the first three finishers. Such a position is required to achieve a podium finish in finals, or typically to achieve a qualification from preliminary heats. The 800-m middle distance running event is complex, partly

The Effect of Foam Rolling on Recovery Between Two Eight Hundred Metre Runs

dynamic joint ROM during a running stride. The present study specifically investigated the influence of FR on middle distance running. The findings may be limited to that activity or individuals conditioned for that intensity and duration of exercise. Another limitation is that the FR protocol used in the present study took approximately 10 min to complete. FR bouts of different durations may alter outcomes. The findings of this investigation may be limited to middle distance running on a treadmill as well. While subjects were provided with a familiarization session
