The article discusses research which was conducted to investigate whether a different number of repetitions could be performed on the individual muscle actions of the bench press and squat in men and women. Researchers evaluated 10 resistance trained men and 10 trained women who performed the squat and bench press. They found that there were significant diferences betwen three muscle actions that they investigated across both exercises and sexes, that women performed more eccentric and concentric actions on the bench press and men performed more combined repetitions.

The article reports on research which was conducted to investigate the relationship between physical performance, epinephrine, and melatonin concentrations in the early morning and late afternoon in elite collegiate male track and field athletes. Researchers evaluated several jumpers and sprinters. They found that a preworkout elevation of epinephrine may offset concentrations of melatonin in the morning and help track athletes maintain maximum muscle force and power and that quickness and power were worse in athletes in the morning.

The article discusses a study on the effects of a multinutritional supplement on cytokine responses to resistance exercise and training. The supplement includes amino acids, carbohydrates, and β-hydroxy-β-methylbutyrate which was administered to 17 healthy, college-aged men under a Muscle Armor™ or placebo supplement for 12 weeks. Findings suggest that the supplementation altered the cytokine response to acute resistance exercise.

The article reports on research which investigated the effects fatigue from resistance training had on barbell back squat biomechanics. Researchers evaluated 12 men and 13 women who performed several weight lifting tasks. They found that the technique changes that occur in high repetition sets do not favor optimal strength development and may increase the risk of injury and may also lead to questions about the safety and efficacy of such resistance training programming.

The article reports on research which investigated the effects high intensity short rest resistance exercise had on muscle damage markers in men and women. Researchers evaluated nine male and nine female subjects. They found that women demonstrated a faster inflammatory response with increased acute damage and that men demonstrated a greater prolonged damage response.

The article focuses on research into the effect that prioritising resistance training in National Collegiate Athletic Association Division I Football summer training had on student athletes. It examined three different resistance training programs and measured athlete body mass, one-repetition maximum bench press, back squat, power clean, and countermovement vertical jump height. It comments on the benefit of a performance program with a prioritization on strength and nonlinear model.

The article discusses research which was conducted to investigate changes in the athletic performance of low land young athletes during a week long high altitude alpine ski racing camp. Researchers evaluated 11 youth ski racers. They found that approximately 20% of low land athletes have signs and symptoms of acute mountain sickness and that any negative performance changes seen in the athletes during the week declined as athletes became acclimated to altitude changes.

The article discusses the effects of high-intensity, short rest (HI/SR) resistance exercise protocols on adrenal cortical function in trained male and female athletes. Subjects performed exercises such as back squat, bench press, and deadlift at descending repetitions. The study looked at possible sex differences in metabolic factors such as lactate and cortisol levels, heart rate, and rating of perceived exertion. Also noted is the risk of overtraining in HI/SR exercise.

The article discusses research which was conducted to investigate changes in creatine kinase (CK) and cortisol in national Collegiate Athletic Association division I American football players during a playing season. Researchers evaluated 22 players. They found that no significant changes in CK concentrations were observed over the season and that no changes in serum cortisol concentrations were observed.

The article discusses research investigating effects of resistance training fatigue on joint biomechanics. The authors argue that resistance training performed with short rest can result in substantial fatigue that can have a negative impact on exercise technique. The results of an examination of what residual movement effects may exist after a resistance training workout in 12 men with six months of resistance training experience as a result of fatigue are discussed.

The article reports on the challenges, including overtraining and a need for adequate rest and recovery, which are associated with providing strength training to soldiers in 2012. A discussion of the objectives of military strength training, and of changes in military warfare which have resulted in a need for an updated military fitness training regimens, is presented.
