The purpose of this article is to give an overview and theoretical framework on the concept of periodized nutrition—with an emphasis on adequate carbohydrate intake to enhance performance.
This review analyzes relevant variables involved in acute interference effects of concurrent training (CT) sessions of aerobic exercise followed by strength exercises. The aerobic exercise intensity, mode, volume, duration of recovery interval between exercises, muscle groups involved, and utilization of ergogenic aids are the variables identified in this review. High-intensity interval aerobic exercises result in more pronounced negative effects on strength-endurance exercise but not in maximal strength. Cycling results in more negative effects on strength endurance performance exercise than running. A 4-hour to 8-hour recovery interval seems to be enough to avoid interference on strength-endurance performance. Reduction in strength-endurance performance is located in muscle groups involved in both exercises. Low aerobic exercise volume (3 km) with; 18 minutes of duration does not diminish strength endurance, whereas higher volumes (5 and 7 km) with ;30 and ;42 minutes of duration, respectively, generate impairments. Caffeine, carbohydrate, and beta-alanine are not able to revert the deleterious effect on strength-endurance performance, whereas creatine and capsaicin analog supplementation are. Thus, these variables must be taken into consideration to prescribe and organize a CT session. This information may help coaches to organize exercise sessions that minimize or avoid the impairment in strength performance after aerobic exercises.
High-intensity strength training paired with explosive, high-velocity movements is suggested to enhance endurance performance. It is recommended that a practical approach be taken when implementing this model of strength training, which would involve a thorough preparatory period.

Scientific research has identified lactate threshold (LT) and maximal exercise performance as being very important contributors to endurance performance. A well-designed endurance training program can lead to improvement in both LT and maximal exercise performance within a single season and from season to season.
This excerpt from NSCA’s Guide to Sport and Exercise Nutrition discusses the research surrounding the timing of hydration and its impact on sport performance for those participating in aerobic endurance exercise.
Knowing when to train and how much time to devote to training each of the three energy systems is an important ingredient of success in endurance sports. This knowledge is also reflected in a well-designed and scientifically-based training plan.
Various aspects of resistance training, such as specific exercises chosen, workout structure, resistance used, volume (repetitions and sets), rest intervals between sets, and training frequency, can be manipulated to mold the strength training program to best meet an endurance athlete’s goals.
When integrating resistance training, endurance athletes must ensure that the sessions or workouts are sequenced in the context of the overall workload. Giving careful thought to these factors when designing the training plan will increase the chances of success.
