Researchers had three groups of professional cyclists cycle for one hour at different levels of intensity. Members of groups A, B, and C cycled at rates that sustained, for an hour, pulses of about 60 percent, 70 percent, and 85 percent, respectively, of the recommended maximum pulse rate for recreational cyclists. Most members of Group A reported being less depressed and angry afterward. Most members of Group B did not report these benefits. Most members of Group C reported feeling worse in these respects than before the exercise.

Summary
Researchers conducted a study where three groups of cyclists cycled for one hour at differing levels of intensity. Group A cycled at 60% of the recommended maximum pulse rate, Group B cycled at 70%, and Group C cycled at 85%. Most of the members of Group A reported feeling less depressed and angry afterward. Most of Group B did not report these benefits. Most of Group C said that they felt more depressed and angry than before the exercise.

Strongly Supported Conclusions
The intensity of an exercise can impact someone’s psychological state

A
The higher the pulse rate attained in sustained exercise, the less psychological benefit the exercise tends to produce.
The stimulus only provides data between 60-85%. It could be that higher pulse rates provide great psychological benefits like a runner’s high. It is too strong to suggest that the higher the pulse rate, the less physiological benefits are provided.
B
The effect that a period of cycling has on the mood of professional cyclists tends to depend at least in part on how intense the cycling is.
The stimulus well supports the idea that the intensity of a workout impacts the mood of professional cyclers. Those whose heart rates were lower (less intense workout) felt much better than those with a higher pulse rate (more intense workout).
C
For professional cyclists, the best exercise from the point of view of improving mood is cycling that pushes the pulse no higher than 60 percent of the maximum pulse rate.
There is no information about what the *best* exercise is for cyclists. You have to assume that feeling less depressed and angry are the only criteria for what makes something the best exercise for professional cyclists.
D
Physical factors, including pulse rate, contribute as much to depression as do psychological factors.
The stimulus does compare physical factors and other psychological factors (much less that they contribute as much).
E
Moderate cycling tends to benefit professional cyclists physically as much or more than intense cycling.
The stimulus does not mention how much physical benefit moderate vs. intense cycling provides.
