Exercise Snacks for Upper Body Fitness

This trial aims to determine if short bursts of upper-body exercises, known as "exercise snacks," can enhance strength, endurance, and power. Participants will either perform push-ups and planks at submaximal effort several times a day, at maximal effort once a day, or maintain their normal routine without added exercise. The researchers aim to discover if spreading exercise into smaller sessions is as effective as completing it all at once. Healthy college students not currently engaged in upper-body resistance training are ideal candidates for this trial. This research could lead to more efficient workout strategies for building upper-body strength without requiring significant time or effort. As an unphased trial, this study provides a unique opportunity to contribute to innovative exercise research that could benefit fitness routines.

The trial excludes participants who use medications that may significantly affect muscle performance, fatigue, or neuromuscular function. If you are taking such medications, you may not be eligible to participate.

Research shows that "exercise snacks," short bursts of physical activity, are generally safe. Studies have found that these small exercises can improve fitness without causing harm. For more intense exercise snacks, evidence suggests these quick, vigorous activities benefit heart and lung health.

For less intense, repeated exercise snacks, research supports their safety, with no significant side effects reported. This method involves doing easier activities more often, which can still enhance fitness. Participants have well-tolerated both types of exercise snacks, with no major problems reported.

Researchers are excited about the "Exercise Snacks" trial because it explores new and convenient ways to boost upper body fitness without traditional long workouts. Instead of the usual gym sessions, the trial tests quick bursts of exercises called "exercise snacks." These can be done in short sessions, either as a maximal effort once a day or in submaximal, repeated efforts spread throughout the day. This approach could make staying fit more accessible and less time-consuming, potentially fitting into busy schedules better than conventional exercise routines.

Research shows that short, intense exercise sessions, known as "exercise snacks," can improve upper-body strength, endurance, and power. This trial will compare different types of exercise snacks. Participants in the maximal effort one-time exercise snack (MO_ES) group will perform the maximum number of push-ups and hold a plank position for their maximum time, once per day, three days per week. This approach has increased muscle strength and built lean body mass. Meanwhile, those in the submaximal repeated effort exercise snack (SMR_ES) group will perform approximately 33% of their individual maximum push-ups and plank time, three times per day, three days per week. Even small amounts of repeated, less intense exercises can boost muscle strength and other fitness outcomes. Both methods effectively enhance fitness, offering a flexible way to build strength and endurance.¹³⁶⁷⁸
