Study: Hamstring injury occurrence in elite soccer players after preseason strength training with eccentric overload.

Askling C, Karlsson J, Thorstensson A. Hamstring injury occurrence in elite soccer players after preseason strength training with eccentric overload. Scand J Med Sci Sports. 2003 Aug;13(4):244-50.

Another study focusing on elite soccer players with a preseason eccentric overload strength program for the hamstring muscle group.

30 players from two premier-league division teams in Sweden were divided into 2 groups. Group 1 added a preseason eccentric overload strength program 1-2 times a week for 10 weeks while group 2 did not do eccentric overload exercises.

All hamstring injuries were registered during 10 months. The eccentric overload training group 1 hat 3 hamstring injuries within 10 months, while the group 2 with traditional training had 10 hamstring injuries (+333%). It is truly astonishing that eccentric overload plays such a vital role in preseason training for hamstring injury prevention.

The results showed that the occurrence of hamstring strain injuries was clearly lower in the training group (3/15) than in the control group (10/15). In addition, there were significant increases in strength and speed in the training group.

Eccentric overload training proves again its capabilities for injury prevention and sprint speed increases at already trained professional athletes.

Study: Effects of a 10-week in-season eccentric-overload training program on muscle-injury prevention and performance in junior elite soccer players.

de Hoyo M, Pozzo M, Sañudo B, Carrasco L, Gonzalo-Skok O, Domínguez-Cobo S, Morán-Camacho E. Effects of a 10-week in-season eccentric-overload training program on muscle-injury prevention and performance in junior elite soccer players. Int J Sports Physiol Perform. 2015 Jan;10(1):46-52.

36 young players (U-17 to U-19) divided into 2 groups. One group conducted an additional eccentric overload training program with 1 or 2 sessions/week with 3-6 sets with 6 repetitions for 10 weeks while the other group followed the traditional trainings plan.

The eccentric overload training group had a lower injuries per 1000 hour match play and lower numbers of absence days per injury. The eccentric overload training group had better 10m flying sprint time and 20m sprint times. Countermovement jumps performance increased too in the eccentric overload training group.

Overall a full point win for eccentric overload training for muscle injury prevention as well as for increasing linear sprinting speed and jumping performance of junior elite soccer players.

Study: Effects of In-Season Inertial Resistance Training With Eccentric Overload in a Sports Population at Risk for Patellar Tendinopathy.

Gual G, Fort-Vanmeerhaeghe A, Romero-Rodríguez D, Tesch PA. Effects of In-Season Inertial Resistance Training With Eccentric Overload in a Sports Population at Risk for Patellar Tendinopathy. J Strength Cond Res. 2016 Jul;30(7):1834-42.

Volleyball and basketball players are a risk group for patellar tendinopathy. 38 woman and 43 men of 8 different basketball and volleyball teams were divided into 2 groups. One group performed 1 weekly eccentric overload training session for 24 weeks in addition to their current training schedule, while the other group just follow their current training schedule. The weekly eccentric overload session consisted of 4 sets of 8 repetitions squats.

The results show that the countermovement jumps and lower limb muscle power were both significantly better with the additional eccentric overload training. Additionally eccentric overload training does not trigger any patellar tendon complaints, which makes it a safe and vital tool for professional athletes.

This study takes a look at changes in muscle structures and tendons after eccentric overload training and 3 consecutive running days.

20 heathy runners split in 2 groups. Group 1 conducted an eccentric overload training focusing on squats for 6 weeks followed by a 3 consecutive running days. The control group did not do any eccentric training.

The most important results is that the ultrasound and Doppler imaging showed an improvement of the tissue quality (significant increase in cross-sectional area) of the patellar tendon in the eccentric overload group.

This makes eccentric overload training a suitable tool for injury prevention.

Study: Effects of adding a weekly eccentric-overload training session on strength and athletic performance in team-handball players.

Sabido R, Hernández-Davó JL, Botella J, Navarro A, Tous-Fajardo J. Effects of adding a weekly eccentric-overload training session on strength and athletic performance in team-handball players. Eur J Sport Sci. 2017 Jun;17(5):530-538.

In the study a weekly eccentric overload session were added to the regular training schedule of a handball team for 7 weeks. The eccentric overload group (11 people) added 1 session per week with 4 sets of 8 repetitions with bilateral half-squat and unilateral lunge exercises compared to the control group (7 people).

The eccentric overload group showed an increase in triple hop distance performance. Additionally the eccentric overload group showed higher improvements in eccentric and concentric power of the half-squat (increases between +6.5% and +22%) and lunge exercises (increases between +13.1% and +24.9%)

In summary, important pro-sports related performances like functional jumping performance, power output can be improved with eccentric overload training. Already 1 additional eccentric overload session per week can result in optimizing the professional athlete’s performances and can win key plays and key games for your team.

Study: The effects of eccentric versus concentric resistance training on muscle strength and mass in healthy adults: a systematic review with meta-analysis.

Roig M, O’Brien K, Kirk G, Murray R, McKinnon P, Shadgan B, Reid WD. The effects of eccentric versus concentric resistance training on muscle strength and mass in healthy adults: a systematic review with meta-analysis. Br J Sports Med. 2009 Aug;43(8):556-68.

This study is interesting, because it looks at the results of eccentric training on muscle mass and muscle cross-sectional area. Both parameters heavily define how your body looks and how tight it feels.

This study include 20 randomized controlled trial studies.

First, the results of this meta-analysis show that eccentric exercise at higher intensities increases total and eccentric strength more significantly than standard concentric training.

Second, eccentric training at high intensities is more growing muscles (measured in muscle girth) more effectively.

Third, eccentric training at high intensities show a notably trends towards increasing muscle cross-sectional area (measured with magnetic resonance imaging or computerised tomography), which effect how tight your muscles feels.

Study: Muscular performance after concentric and eccentric exercise in trained men.

Vikne H, Refsnes PE, Ekmark M, Medbø JI, Gundersen V, Gundersen K. Muscular performance after concentric and eccentric exercise in trained men. Med Sci Sports Exerc. 2006 Oct;38(10):1770-81.

This study are about previously resistance-trained men (age 26.9 +/- 3.4 yr). The effects of concentric and eccentric training is compared on performance and structural muscle measures.

The concentric training group (8 people) and the eccentric training group (9 people) performed during 12 week elbow flexors workouts. Measurement criteria were the angular velocity at standard loads and maximum concentric and eccentric strength. Additionally hypertrophy (muscle growth) were measured on muscle cross-sectional areas and single cell cross-sectional areas.

The results for the strength results show that concentric strength increased by +18% for the concentric group and +14% for the eccentric group. Eccentric strength increased by +9% for the concentric group and +26% for the eccentric group. Maximum angular velocity increased similar in both groups.

The results for the muscle mass growth results show that the cross-sectional area of both the elbow flexors did not increase at the concentric group but did increase with +11% on the eccentric group, which is impressive. Additionally the type I and type IIA fibers did not increase in the concentric group but increased in the eccentric group. In addition, the type II fibers of the relative cross-sectional area increase from 64% to 73% in the eccentric training group.

In conclusion, the muscle strength results were in small favor for eccentric training and the muscle mass growth results were in big favor for the eccentric training compared to traditional weight-based concentric training.

Study: Skeletal muscle functional and structural adaptations after eccentric overload flywheel resistance training: A systematic review and meta-analysis

Sergio Maroto Izquierdo, David García-López, Rodrigo Fernandez-Gonzalo, Jose Antonio de Paz. Skeletal muscle functional and structural adaptations after eccentric overload flywheel resistance training: A systematic review and meta-analysis. Journal of Science and Medicine in Sport. 2017 Mar; 20:943-951.

This meta-analysis summarizes the results of eccentric overload training quite accurate: free weights and weight-stack machines are still the most popular resistance training machine, but eccentric overload devices result in greater improvements in muscle power and muscle growth.

Additionally eccentric overload appear to increase vertical jump height and running speed.

The most effective eccentric overload mode is described as high speed workout with low inertia.
