Endurance exercise increases the amount of mitochondria (energy powerhouses of muscle cells) per area of muscle, increasing the amount of usable energy - which skeletal muscle fibers with the greatest endurance rely on - according to the Nitric Oxide review.Endurance exercise training increases myoglobin (a protein that carries and stores oxygen in muscle cells) content, likely increasing the oxygen reserve in the muscle, according to the Nitric Oxide review.Endurance training enables your body to use proportionally more fat at a given exercise intensity, sparing muscle glycogen (your muscles' fuel source) and allowing you to exercise longer, according to a December 2015 review in Nutrition & Metabolism.Oxygen supply to the muscles is critical for maintaining endurance, as muscles fatigue very rapidly without sufficient oxygen supply, according to a May 2012 review in Nitric Oxide. Out of the options of Body Size and Composition, Muscle Strength, Muscular Endurance, Power, Speed / Quickness, Agility, Flexibility, Balance and Coordination, and Cardiovascular Endurance, the factors which are considered most important by the readers of this. Endurance training increases the number of capillaries per area of muscle, increasing oxygen supply to the muscle. We have a poll about the component of fitness most important for success in soccer.Endurance training increases the aerobic capacity of type IIa and IIb muscle fibers in particular, resulting in more fibers with fast-contracting, fatigue-resistant properties - enabling you to run longer distances, according to a landmark November 2001 article in the Physical Therapy & Rehabilitation Journal..When building this type of endurance, light loads are used so the player can continue to endure for a significant period of time.
Long-term muscular endurance: Marathoners, rowers, basketball players and other endurance-sport athletes with games or races that last more than a couple of minutes at a time need long-term muscular endurance.With training, short-term endurance lets the players deal with fatigue and lactic acid build-up in the muscles. These sports include sprinting, football and soccer. Short-term muscular endurance: Sports that require short, intense bursts of activity require an athlete to have short-term muscular endurance.With training, power endurance can be converted into explosive power, which helps the athlete resist fatigue during these repetitive efforts. Having power endurance means the athlete can create that necessary power with each movement. Power endurance: Baseball players, sprinters, wrestlers, tennis players and freestyle swimmers all must producer powerful movements and repeat them time and again for success.Future research should investigate how best to implement accentuated eccentric loading and variable resistance training and examine how initial strength affects an athlete's ability to improve their performance following various training methods.
Stronger athletes may begin to emphasize power-type training while maintaining/improving their strength. Weaker athletes should focus on developing strength before emphasizing power-type training. While 2- to 5-min interset rest intervals may produce the greatest strength-power benefits, rest interval length may vary based an athlete's training age, fiber type, and genetics. Multiple sets appear to produce superior training benefits compared to single sets however, an athlete's training status and the dose-response relationship must be considered. Indeed, programming that combines heavy and light loads may improve strength and underpin other strength-power characteristics.
Training to failure may not be necessary to improve maximum muscular strength and is likely not necessary for maximum gains in strength. Bodyweight exercise, isolation exercises, plyometric exercise, unilateral exercise, and kettlebell training may be limited in their potential to improve maximal strength but are still relevant to strength development by challenging time-limited force expression and differentially challenging motor demands. Bilateral training, eccentric training and accentuated eccentric loading, and variable resistance training may produce the greatest comprehensive strength adaptations. Although single- and multi-targeted block periodization models may produce the greatest strength-power benefits, concepts within each model must be considered within the limitations of the sport, athletes, and schedules. Strength is underpinned by a combination of morphological and neural factors including muscle cross-sectional area and architecture, musculotendinous stiffness, motor unit recruitment, rate coding, motor unit synchronization, and neuromuscular inhibition. This review covers underlying physiological characteristics and training considerations that may affect muscular strength including improving maximal force expression and time-limited force expression.
