The effect of abdominal strength or endurance exercises on abdominal peak torque and endurance field tests of healthy participants: A randomized controlled trial.

Objective: To compare the effects of muscular endurance and resisted strengthening protocols on abdominal strength and endurance in a sample of young subjects.

Design: Randomized Clinical Trial.

Setting: University fitness laboratory.

Traditional exercises do not have a significant impact on abdominal peak force in healthy young adults.

The abdominals are vital to activities of daily living, for the prevention of lumbar pathologies, and during sport performance. The purpose of this study was to determine if training without external resistance was a sufficient overload to improve abdominal strength as defined by peak force. Seventy-one healthy men and women (age 19-40 years) participated in the 11-week study.

The influence of fitness and body weight on preferred exercise intensity.

Purpose: The purpose of this investigation was to determine the individual and combined effects of aerobic fitness and body weight on physiological responses, perceived exertion, and speed variables during self-selected steady-state treadmill (TM) walking in 60 healthy college-age women.

Methods: The women were placed into one of four categories based on body mass index (BMI) and fitness level, assessed by a graded TM test. Subjects walked continuously on a TM at a self-selected pace for 15 min at a 2.
